Part one: Sensory Evidence
At first the change is harder to see, but as you keeping looking at the picture, it’s evident that the reflection in the water changes from flick to flick.
It is obviously easier as the only part that changes or stands out is the moving part, which happens to be the only alteration.
It took me a while to notice the change in the image. The flashing black and white dots draw your attention, which distracts you from the flashing tree in the background.
Change blindness to a very slow change
It was almost impossible to notice at the beginning, as it was blatantly slow. In order for me to realize the color change of the bottom of the carousal, I had to compare the very first moments of film to the very last moment.
Change is easy to see if it is part of the ‘’center of interest’’
The change in this image is evident, as the center of attention is the part that changes, making it very hard not to notice.
Change blindness in a film sequence
The changes in this short film were actually quite large factors, however I failed to notice all but one. The only one I managed to notice was the item laying next the dead man, that happened be an attention catcher for me.
The Crater Illusion
Out of the six columns of dots, the two on either side appear raised, as they are lighter on top and darker on the bottom, whilst the two middle columns appear recessed, as they are lighter on the bottom and darker on top.
Motion After Effect Illusion
Rocks appear to climb upward after you stare at a waterfall because the neurons in the motion areas of the brain are what experience the fatigue, and when you focus constantly on just the waterfall for example, your neurons get use to focusing on what Is going downward, rather than still or upward.
All of the identical lines point in different directions and the widths and lengths are different, which means, when you focus directly into the middle of the picture, the outside parts, seem to move, similar to that of the waterfall.
Image 1: With the flicker the change is harder to see
On the first image the change was actually very easy to see. Even though the flicker is a little disturbing, the reflection of the barn on the water is very clear and since the color of the barn is very strong orange, the change in the reflection of the barn on the image was easy to see.
Image 2: Without flicker the change is easy to see
On the second image the change is much easier to see, since just one part of the image is changing as the entire rest of the image stays the same. The change is easy to see because it is a very drastic and the color of the barn is strong, so the change is obvious.
Image 3: A mudsplash also can make a big change
On the third image it took me longer to see the change than on the first two images because I stayed more focused on the musplashes than on the rest of the image when I first tried to see the changes, and only then I started ignoring the mudsplashes and trying to find the actual changes in the images. Then I saw that there was a tree on the background that every time the mudsplash appeared the tree also appeared.
Image 4: Change blindness to a very slow change
On the video it was actually not hard to see the change on the ground of the carrousel. I saw that on the beginning of the video the floor was had a very clear orange tone, and I was able to notice when it started to change slowly into purple as the entire image started to become a little darker.
Image 5: The change is easy to see if is part of the “Center of Interest”
On the fifth image the change is extremely easy to see. Even though there is a flicker on the image, since I was only paying attention to the humans that were on the boat because they seemed to be the most important part of the picture, it was very easy to see when they moved a little to the right after the flicker.
Image 6: Change Blindness in a film sequence
On the film it was actually really hard to notice the changes because all the time I was only paying attention to the inspector that was talking and I was only able to notice the replacement of the bear for a knight and of the person who had been killed. All the other changes were really surprising and I could’ve never have imagined 21 changes in that scene.
The Crater Illusion
In the crater illusion shown, the ten dots in the middle appear to be going back and the other ten dots at each side appear to be coming out. Since our brain assumes that light sources are overhead, if the dots are clearer on the top, it means that they are coming out since the bottom part is not being illuminated and the top part is, because a concave object would not have its bottom part illuminated if the light source is overhead. So, the dots on the middle are going back because the part on the bottom is being illuminated and the part on the top is not, because concave object would not have its top illuminated if the light sources are overhead.
Image 1 – Barn Reflection (with flicker): The flicker, or the white flash in the image used to distract the viewer, didn’t affect my ability to spot the distortion in the reflection on the water. Maybe because of its proximity to the object that mostly stands out in the image.
Image 2 – Barn Reflection (without flicker): Because I had already examined the same picture with a flicker, identifying the difference was nowhere next to challenging.
Image 3 – Egyptian Ruins Tree (mud splashes): The “mud splashes,” while distracting at first, ended up helping me find the disappearing tree, as some of the mud splashes are close to the disappearing tree. What surprised me was the pattern the tree had of disappearing for only one slide, instead of disappearing only when there were no mud splashes.
Image 4 – Carrousel floor (Slow change in the color of the floor): This one was the one that took me the longest to find, but wasn’t hard at the same time. It did take me a couple of tries to notice the color of the floor changing, but mostly because, like the image with the tree, I was expecting a background change.
Image 5 – Beach Boat (Center of Interest): This image was the first one I looked at, and maybe for that reason I stayed a little more apprehensive on the changes on the other images. The boat’s central position in the center of the image automatically calls the attention of the viewer, making the boat’s motion to the right extremely apparent, even with the flicker.
Image 6 – “Whodunnit” Video (Awareness Test): The video really sweeps any attentive viewer with the extremely subtle changes to the background objects, such as the paintings, the objects the suspects were holding, the clock beside the victim, the table with flowers next to the inspector, the chairs around the room, the animal’s head behind the police officer and the bear statue being replaced with a medieval suit of armor, all with the clever use of obstructing the viewer’s view of certain angles of the room so the crew could sneak in and change the scenery.
Image 7 – Crater Illusion: An optical illusion instead of a GIF image and a distraction between the changes, this image has three columns with 2X5 circles each. The two outermost columns appear to have raised circles, while the center column has recessed circles. In both columns, one of the sides is white and the color starts darkening to a dark grey, in order to represent the way in which the sun is hitting which side of the picture. By placing the white side on top, the circle appears to be raised, with the shade being formed in the bottom. By placing the dark grey side on top, the circle appears to be recessed, with the light from the sun hitting only one side.
I understand it is late; but, better late than never, I guess.
Assignment b) Motion After Effect Illusion (The Waterfall Effect) – As the paper didn’t ask for any task as we watched the video, I will simply detail my experiences with it. When I first began staring at a simple point of the waterfall, I could feel a certain discomfort in the back of my eyes, as if I were getting drowsy. Then, as I stared at my wallpaper, nothing happened. Still today, I can’t say whether this illusion affects only a portion of the population, whether the design of my wall is inappropriate for this type of illusion or whether I am a special form of invertebrate. What also amazed me is that the man in the video suggested for any viewer in nature to examine a tree so that they could notice the Waterfall Effect. I sure hope that, when he discovers a type of tree with wireless reception, he lets the rest of the scientific community know. I already look forward to my new garden.
Assignment c) Perceived Motion - Maybe some of the reasons as to why the outermost divisions of the picture are the lack of trust one can have with their peripheral vision, which manipulates the dimensions of solid objects not directly stared at, such as the hand (try at your own amusement). Or maybe the small “jumps” the retina takes every 0.2 seconds so it can form, in conjunction with the brain, the colorful and complete image we constantly see.
Great job, thanks.
Image 1 - I had no difficulties to see the change in the images between flicks. The change in the reflection in the water is easily observed; probably due to the very distinct colors of the water and the house, having the brighter color of the house catch my attention. This way, when the flick occurs and the image is changed, i'm concentrated on looking at that part of the image and observing the change becomes an immediate response.
Image 2 - Again the change was easily observed. As well as having the detail of the color of the house and the water(mentioned in the previous answer) I had already seen the same images with the same change.
Image 3 - This time observing the change was much more difficult and only by the third or fourth flicker was I able to see it. I believe that this delay was caused because the change in the image happens in the background of the image, somewhere where I really wasn't paying enough attention. The mud splashes served as a distraction and only after a while was I able to analyze the whole image and identify the change.
Image 4 - I had a lot of trouble identifying this change. The first time I watched the video I couldn't see anything different, but, as I watched it again, and the final image in the end of the video was fresh in my mind and I quickly restarted, it was clear that the color of the floor had changed. I think that because the change happens so slowly and there are many other elements in the image that we focus on, the change is unnoticeable to me.
Image 5 - Different from the previous image, this one had a change that was very easily observed. The boat and the men are immediately identified due to their size and position in the image. They stand out as a main element and were what most caught my attention.
Image 6 - It was very hard for me to identify the 21 changes. The inspector, the corpses and the suspects were caught the main attention and I only focused on them, therefore, the only change I noticed was the dead body.
b) Motion After Effect Illusion
The reason why the rocks appear to climb upward after you stare at a waterfall is because the neurons and cells in our eyes that are sensitive to motion are so fatigued from the continuous downward motion that when you look at something with a pattern that remains still, it will seem that the object is moving upwards.
Nice start. Keep up the good work.
a) Change Blindness Demos
With flicker the change is hard to see
When I first looked at the image I noticed the change in the reflection of the house on the water. Since the house is a big part of the image and there is a contrast in color between the orange house and the blue water, it is really perceptible when its reflection is distorted to the right after the flicker.
Without flicker the change is easy to see
Although I noticed the distortion in the house’s reflection on the water right away in the image with flicker, it was obviously much easier and clearer to see without it.
A mudsplash also can mask a big change
Again, it was really easy to identify the change in the picture: the tree at the right disappears. Although it is not a big part of the image, the contrast of colors between the green tree and the rest of the yellowish picture makes it easy to identify the change.
Change blindness to a very slow change (1.4 Mb .avi)
The change in color of the base of carousel was very difficult to notice. It was so slow that I didn’t see it changing throughout the video when I first watched it, only when I watched for the second time.
The change is easy to see if it is part of the “Center of Interest”
The change in the image is extremely noticeable when you look to it right away: after the flicker, the boat with the people moves to the right. When I look to the picture, the boat with the people is the part that captures my attention, which makes it easy to identify any change.
Change Blindness in a film sequence
I didn’t notice absolutely any change while watching the video, before the changes were revealed. My attention was always I was astonished when so many changes were shown.
The Crater Ilusion
The two columns of dots at the left and the two columns of dots at the right look raised, while the two middle columns look recessed. As stated, our brain assumes that light sources are overhead, so when we see the light coming from the bottom we think it is a hole, like a cave, since there isn’t light overhead.
b) Motion After Effect Illusion
As the assignment sheet already answered, neurons in the motion area of our brain seem to experience fatigue when we look for a while at a continuous downward motion, that’s why rocks appear to climb upward after you stare at a waterfall.
c) Perceived Motion
I do not actually know what might be happening to cause the eye to perceive motion, but I guess it is for a similar reason as the reason why rocks appear to climb upward after we stare at the waterfall, in the previous question: the motion area of our brain might be affected, but I don’t know how, making the image seem it is moving.
Nice work Gabriel.
The Implicit Association Test
I did the IAT Age test, which resulted in a strong automatic preference for young rather than old. I didn’t exactly expect that because I’m neutral in relation to age and that sort of thing. According to the results, such a result was interpreted as I responded faster when young faces and good words appeared, instead of old faces and bad words. This could as a matter of fact be true, but I wasn’t necessarily conscious of it. I don’t think this reflects hidden emotions or anything like that. The fact that the test kept switching where the words were and what they were grouped with was slightly confusing and it was blatantly easier to distinguish and relate the good to the young and the bad to the old, instead of vice versa.
Interesting observation, thanks.
a.) Change Blindness Demos
The change was very easy to spot, despite the flicker that was there. The barn is the main point of focus of the picture and it also has the brightest colors so your eye is immediately drawn to it. Also, the change between flickers is so great that your eye can easily see the movement of the two reflections. Lastly, the color of the lake is bright blue and draws attention that you can see the change of the reflection of the barn.
Without the flicker, there is no distraction so your eye is immediately drawn to the motion in the reflection of the lake. The reflection moves from one spot to the other very obviously. Also, the rest of the picture stays exactly the same, so you can easily spot the motion.
Although the mud-splashes were a big distraction, the tree disappearing was easily noticeable. The tree was not near any of the flickering splashes in the picture which made the changing tree easier to spot. Also, the green tree stood out against the grey sky, so the contrast also makes the change stand out.
This video was difficult to see any change. I watched it twice through without spotting anything. Then I paused the video at the beginning and jumped to the end and was surprised at how obvious the change was. I could definitely tell the color of the carousel changed from an orange color to purple. It was hard to spot watching the video in its entirety because the change was so small and also because the color change was very slight over time.
The change that occurred was movement between the placement of the people and the canoe. Because the canoe and the people are the main object of the photo it is easy to tell where and when they move despite the flicker. Also if you look at the canoe in relation to the other stationary objects in the photo you can see the motion without difficulty.
The small changes to the room were hard to see especially as the scene was playing out. The decoration of the room had no relevance to the crime so I didn't notice or attempt to pay attention to what the color of the carpet was. However after seeing the playback I was surprised I didn't notice the obvious changes such as the switching of the clock or the different man on the rug. I was too focused on trying to figure out who killed the man.
The Crater Illusion:
On the right side and left side of the picture, the dots look raised up above the surface of the picture. However, in the middle set of dots, they look recessed. I realized something strange though: if you flip the picture upside down then the middle dots look raised and the outer dots look recessed. This is because now the dark side of the dot is now on the opposite side making it appear like the light is coming from the opposite angle. The shading of the circle and whether the dark side is on the top of the circle or the bottom causes the circle to look either raised or recessed. If the dark side is on the top, the circles shade from dark to light making the circle look like it caves in. If the shading goes from light to dark then the circle looks raised.
b) Motion After Effect Illusion
The first time I did this experiment I couldn't see the illusion. I stared at the waterfall in the video but because of the motion, my eyes couldn't focus on one spot. I tried it again looking at the moving water on a lake but the water wasn't moving fast enough. I watched the video again and this time I trained my eyes to stay in one spot and fought the resistance to follow the water down. This created the optical illusion so that when I looked at the rock the rocked looked like it was moving upward. Naturally, your eye wants to follow the motion of the water down, but fighting the natural instinct and training your eye to stay in one spot causes your eyes to become tired. Therefore, when you look at the stationary rock, the rock looks like it is floating upward because your eyes still want to follow the motion of the waterfall. Its the neurons in our brains that become tired and continue to perceive motion when they look at a stationary object after staring at motion for a long time.
c.) Perceived Motion
The eye perceives motion because the lines switch directions and head in opposite ways making it look like they are moving away from each other. Also the opposite moving lines are emphasized by the surrounding grey lines. As the black and white lines get closer together and turn towards grey the image looks 3D. The eye perceives more motion because now the eye follows the opposite lines in both directions and looks into the center of the image because it looks like it keeps going forever. These two effects occurring at the same time cause the eye to perceive motion.
Part One: Sensory Evidence
A). The animations observed suffered deliberate changes which are not easily noticed by human beings. The effects present in the animations (flicker and mudsplash) are able to hidden the differences present in the images before and after their occurrence because they are able to deviate the attention of the observer from the sudden changes towards the splendor of the actual effects. Therefore, what is being failed to be noticed by humans are the details that ones are not actually looking for as they take a first glance at an object or an image. In the first gif, the flicker effect is used in order to make the observer fail to recall the position of the house in its reflection on the pond, thereby making the discrete change in the barn’s reflection imperceptible by most individuals. In the obelisk picture frame, the change is regarding the existence of a tree in the horizon. After the mudsplash effect takes place and the attention of the observer is focused in the points in which the stains appear, the tree that was once present in the right of the landscape vanishes. If ones were looking at two pictures, one containing a tree and the other not, they would be definitely be able to comprehend that there has been a change. However, considering that the mudsplash effect would deviate the attention of the observer from the actual details in the image, they, such as most of the humans, will not be able to see what they are not looking for. In the beach image, the flicker effect is once again used to disable the spectator’s attention to the position of an object in the scene, in this case the canoe. Thus, the canoe moves but the audience is not able to see. In the “Who Dunnit?” scene there are 21 changes to the scenery and to the actor’s clothes. Still, ones are not able to acknowledge the changes that occur. This happens due to the reason that what is trying to be seen by ones as they watch the movie is not the changes to the scenery, but the detection of the assassin in the scene, ratifying the thesis that people are blind to what they do not want to see or look for.
The Crater Illusion demonstrates how the vices among human thought affect how ones see an image. People have always assumed that light sources are overhead, since the main source of light of planet Earth, the sun, shines from above one’s head. Therefore, as ones observe an image such as the Crater Illusion, which includes both the presence of light on the bottom as well as on the top of the dots present, they see the dots with the light on top as raised bubbles while the dots with their bottoms lightened are seen as recessed.
Part I - Sensory Evidence - Motion After Illusion
The Waterfall Effect can be explained as a response of the body to the fatigue caused to the neurons that detect downward motion. Since the waterfall’s movement is simply downward, only the brain cells that are related to the observation of downward motion are used, thus, if ones stare for prolonged periods of time to a point in a waterfall these brain cells will be less responsive. As a consequence, when ones look at a stationary object the brain cells that capture upward movement would be preponderant over the ones with the ability to analyze downward motion, thereby making the stationary objects slightly move.
Part I - Sensory Evidence - Percieved Motion
The optical illusion of perceived motion is one of the most famous artifices of the field of illusions. Even though there is no motion in the illusion, the human brain is able to detect a slight spiral movement within the image. This occurs because of the white and black spiral pattern that appears in the picture. The brain probably assembles that the pattern is continuous and thus makes the human perception have a correspondent motion to the spiral pattern, thus creating this sense of spiral movement.
Part I - Sensory Evidence - McGurk's Effect
The human understanding of a message spoken by another person does not depend on hearing and vision in an isolated manner. Instead, humans are able to comprehend what is being said by the interaction of these two senses. The McGurk Effect is a clear proof of the interaction between human speech, hearing and vision in order to acquire the correct information that is being emitted by another person. The McGurk Effect exposes to the observer his incapability of understanding what is being said if hearing and vision are not connected. In order to expose the importance of the interconnection of these senses, the McGurk Effect creates a disturbance in the human brain’s superior temporal sulcus (STS), region of the temporal lobe that is responsible for the visual and auditory connection. This disturbance occurs for the reason that there is a video record which contains non-matching audio and images. The human brain, therefore, is not able to associate what is the connection between the two fragments of video and audio, making the observer hear an alternative sound. This alternative sound will neither be the sound emitted by the audio, nor the message suggested by the visual stimuli. Instead it will be a disordered compilation of the syllables presented by each of the senses.
With flicker: Originally looking at the picture I was sort of confused on the change occurring. As I looked closer and for a longer period of time I began to see the change in the reflection from each flick
Without flicker: For this new picture there is much less time between the changes and our eyes during each blink can notice the change quite easily unlike the previous one which took some time.
Mudsplash: This change took even longer to notice because there was no definite pattern. Even when the dots seemed to disappear it still did not change the picture. Only on the second rotation does the tree move making it much more difficult.
Change blindness to a very slow change: The video moved so slowly that it bored me. I hardly noticed any change and the only way it seemed to notice it was to pause at the first second and last second and see the difference to notice the change in the floor color.
Change is easy to see if it is part of the ‘’center of interest’’: The change in this picture is much easier to notice. The change here, unlike previous pictures, happens in the center making it easier for the eye to catch.
Change blindness in a film sequence: The film moved from side to side and up and down. It was difficult to focus on any one object even if you knew something was going to happen. I tried to look at the left side of the room but the camera kept shifting so I never noticed the change when it came back.
The Crater Illusion
There are 6 columns of dots. 2 sets on each side seem to be raised while the middle 2 seem to be lowered. I think it is due to excellent shading exemplifying how light would be reflected off of an object that is raised versus and object that is lowered.
Motion after Effect Illusion
After looking at the waterfall for more than 30 seconds my eyes began to feel heavy. As I looked constantly the water that was initially at my point had fallen down and new water now arrived. This happened over and over again and felt like something was weighing down on my eyes. After looking at a different object I imagined it was moving upwardjust like the water fall as the pattern was also shaped upward.
It seems that as you look closer to the center the rectangles get much smaller. Normally when you look at something in the distance the area encompassing it seems to be much smaller than the area around you. This same feeling comes when looking at this picture. On top of that the patterns are placed in a spiral formation making it look like you are looking into a hole that is spinning.
The Implicit Association Test
I did the test of differentiating between European Americans and Asian Americans and how much each is considered American. I thought that I would come out as neutral as I am of Asian descent myself and be fair in terms of which I thought were American. It turns out that I mainly associated the European Americans to be the true Americans. I think this is the thinking in my sub-conscious but I don’t really know about it. It makes a lot of sense especially because of this country’s past racism and interferences from entertainment media.
In the image with flicker it takes longer for your brains to realize that something in the picture was changed, because there is a flicker in between the changed images that takes away our attention from the picture.
The brain notices faster the image has been changed because it is the only thing that is altered, therefore the only thing the brain has to focus on.
Even though my brain processed the fact that something was missing from the picture, it took a while for me to realize what was that was missing.
When you stare to something that is moving for a period of time and then move your eyes, things seem to be moving to the opposite direction for a short time.
Center of Interest:
When the center of the image changes, even if there is a flicker the brain is able to notice the change.
The optical effect on the first image in which the flicker is used is pretty easy to identify. The reflection of the barn over the water is easily recognized while it changes its position on the water because the “warm”, reddish barn highly contrasts with blue/greenish tones, also considered in the arts area as the “cold colors”, present in the rest of the scenario. The flicker actually helps the person who observes the image because with the flick or pause between the changes in the position of the reflection, its displacement becomes more evident to the naked eye.
Without the flicker, I would say that the change in the position of the reflection of the barn over the water is less easier to identify because there is no pause between the changes of position that make it clearer to the observer that the change has, indeed, occurred. On the other hand, because the image is the same as the previous one, it is also easy to recognize the change because the red barn highly contrasts to the colors of the scenario and also, our eyes are already trained to identify the change in reflection because we had already observed a similar change before.
The change is hard to identify, unlike the 2 previous images, because the change occurs every second time, therefore, when you observe the image only after one mudsplash it does not change and so you automatically believe that nothing will happen on the second mudsplash because it didn’t in the first. Also, although the tree that disappears and appears is green and the rest of the scenario is kind of yellowish, they do not contrast much because there are other green trees on the side of the tree that disappears, which also make it harder to see.
Change Blindness to Very Slow Change
It is apparently impossible to identify the change in the picture. After three attempts of watching the gradual change, I failed in identifying it. I could only identify the change in the picture (the bottom of the carrousel going from red to lilac) due to posts on the TOK blog, in which they described the change. However, when I came back to the video already knowing that the change relied on the bottom of the carrousel, I could still observe that its color very slowly changes from red to lilac.
Center of Interest
The change in the image is very easy to identify because as the effect itself is entitled, the change is “part of the center of the image”. Also, because there is a pause between the image changes, the eyes are automatically prepared to recognize a change in the image.
Change Blindness in a film sequence
Surprisingly, I failed to notice all of the 21 changes in the film sequence. As the video already suggests after the scene is acted out, that it is hard identify changes in things we are not looking for. Therefore, I could only identify the changes, which are actually pretty significant changes (don’t know how I couldn’t get one of them) after the video was shown from a different perspective in which the staff that makes the modifications is shown.
The Crater Illusion
This optical illusion is specifically interesting because depending on which perspective the person who observes it has, the circles will look either raised or recess. If the person who is observing the circles looks them as they are, then the 4 outer columns seem to have their circles raised whereas the 2 middle ones seem to be recessed. However, if the person stares at them with the paper lying upside down, than they would see the opposite- the 2 middle columns raised and the 2 outer ones recessed. This happens because the color of the top and bottom of the circles is what causes us to be considered either raised or recessed. When the darkest part of the circles is the top, then they appear to be recessed while the darker they look on the bottom, the more they look rose.
Motion After Effect Illusion
The reason why the rocks seem climb upward is because our eyes are already fixed at a point of downward motion. Therefore, they become fatigued from the excessively downward pattern and consequently, the neurons of motion in the areas of the brain associate the rocks with upward motion. It is a specifically hard effect to be observed because we can actually feel the fatigue in our eyes, as it doesn’t remain in theory since our eyes hurt when they’ve observed the waterfall for over 15 sec.
What might be causing the eye to perceive motion are the same neurons of motion that become fatigued from staring mostly at the center of the image ((as in my case). After we look too much ate the center of the image, which is the part we automatically stare the most at because it is position right on the middle of the image, the outer parts start moving due to the same brain activity that makes us feel like the rocks are moving upward in the previous optical illusion. Also, the difference i
What might be causing the eye to perceive motion are the same neurons of motion that become fatigued from staring mostly at the center of the image ((as in my case). After we look too much ate the center of the image, which is the part we automatically stare the most at because it is position right on the middle of the image, the outer parts start moving due to the same brain activity that makes us feel like the rocks are moving upward in the previous optical illusion. Also, the difference in sizes and colors in the image plays major role is our eyes in order for motion to be perceived since each circle, subdivided by grey lines, contain one black and one white part composing the circular form rather than being one color plainly.
The McGurk effect demonstrates the interaction of hearing, speaking, and viewing as it tests the 3 different senses individually and together to prove their efficiencies. In the first attempt, in which we only exercise the ears, we hear it as “ha ha ha”. However, when there is no sound, we think that the lady is actually pronouncing “da da da”. Only in the last attempt, in which all 3 senses are tested, it appears that she says “ha ha ha”. This leads us to the conclusion that the McGurk effect is an auditory illusion, a great way to show that the accurate perception of information involves the participation of more than one sense. Therefore, the perception is more accurate in the last trial, in the example, because all 3 senses are combined.
Implicit Association Test or Should it Be Called the Typing Ability Test?
I tried the age test (young versus adult) and for my surprise, it didn’t turn out as I would have predicted, for before taking the test, I held the conviction that I thought of young and old people similarly, but in the end, though, the data suggested a slight automatic preference for young compared to old. However, I don’t consider this test as an indicator of the ultimate reality, for I believe other factors rather than the unconscious led to such results. I am left-handed; therefore, my ability to type with the left hand is greater than that of the right, which means that not necessarily I associated pictures of old people to “bad”, as it is classified in the test, but because I couldn’t type as fast as I could with the other hand. Thus, I don’t believe that the test judges our hidden attitudes, yet your typing skills, which gives a controversial spectrum to the Implicit Association Test.
