3b Mental Rotation
1. The results obtained in this experiment confirm that the recognition models predict quite well that familiarity or experience plays a prominent role in the recognition of the 3D blocks. It seems that in the rotation of these images familiarity plays a very important role, since it can be assumed that if familiarity is true, then subjects who are familiar with any object or behavior will find it easier to make a mental rotation.
2.

The results showed the typical effect of mental rotation on response times. There were moments when I could not tell if the shapes were different or the same. As when a rotated object is presented to us, we mentally tend to turn it into its usual position. We first rotate it mentally until it is placed vertically,

    The purpose of this experiment is to determine the response time for dominant and non-dominant hand for visual stimuli, and using only dominant hand to test auditory and tactile response. Also, to test involuntary the response time for the reflex of the knee from calculating the distance. Based on my group hypothesis, we said that visual stimulus dominant hand had a faster response time than non-dominant hand because the dominant hand is use more often thus repetition creates stronger connection. For only dominant we said that auditory response has the fastest reaction time because the auditory stimuli gets process faster compare to tactile and visual that has to travel longer to reach frontal lobe for response decision. For involuntary response,…

    Infants have been shown to have developed depth perception from as young as one week. Bower et al found that infants were able to use retinal disparity. By presenting infants with different information in each eye, making them see something that was 3D, even the youngest of infants at one week old tried o grasp the object, providing evidence that infants have binocular cues and can use retinal disparity as a type of depth cue from a young age. Hofsten et al demonstrated that infants can use the motion parallax using the habituation method. The researchers showed infants a certain display until they had gotten used to it. If the same display was shown again, the infant showed less interest in it. In this study, the infants were shown three rods and were moved about in a chair. One of the rods moved with the infant, creating a motion parallax. The infants were shown three displays that all had a motion parallax involved and preferred the three middle rods because to them it was a new display and was more interesting, thus demonstrating that they had the ability to use motion parallax.…

    Summary: The goal of Gray, Chabris & Braver’s’(2003) study was to determine if individual differences in General Fluid Intelligence (gF) would be more evident in lure trials of the three-back task, both in terms of the performance and neural activation. To accomplish this task Gray, Chabris & Braver (2003) collected a sample of 60 healthy, right-handed, native English-speaking individuals from Washington University and the surrounding community. Gray, Chabris & Braver (2003) first used the Raven’s Advanced Progressive Matrices (APM) to measure the gF of the participants involved in the study, the APM contained 36 questions for the participants to complete. After the gF results were collected Gray, Chabris & Braver (2003) administered the three-back task, in each scanning run participants had to determine if the third face or word in the sequence matched the stimulus three spaces backwards.…

    The experiment tries to show that people can not only create images but also mentally transform them. They present the subjects with two 3D line-drawing of random block shapes. The subjects are asked to decide if the two images are the same object by pressing two different keys on the keyboard. In some cases the two images are the same object with one rotated by some degree. In other cases the two images are mirror images that are similar but not identical. The mirror images are also rotated sometimes. The dependent variable is the reaction time. The independent variables are stimuli that have the same shapes vs. stimuli that have different shapes, and the degree of rotation. The control conditions are the multiple trials and the selection of only correct responses. The hypothesis is that if the reaction time is affected by the degree of rotation of the images, subjects perform the task by mental rotation of the drawings because it takes time to rotate the mental images just like real images. The result shows that the reaction time is indeed affected by the degree of rotation; therefore, it demonstrates the hypothesis that people can mentally rotate images. It takes more time for subjects to react when the degrees of rotation increase. There are some methodology problems in this experiment design. First, the block-shape 3D images are hard to identify even one at a time for some people and the test only takes correct answer into consideration. The repetition of the tests may cause fatigue to some subjects and the correct answers can be generated by random clicking of images. Second, the block-shape objects are not something that we can encounter in the real life so the subjects may have to take extra effort to analyze the images. Finally, the correct answer can be derived by ways other than mental rotation. For example, you can simply just find a starting point of the block-shape images and ‘walk through’ the images to see if the two images have the same ‘route’…

    Reaction time increased as the the letters were rotated away from zero because there is a greater angle the closer you get to 180 degrees, taking longer to mentally roate the images .The decresed reaction time occurs because an object rotated beyond 180 can be flipped the other direction, taking less time to mentally rotate it. Rotating the images mentally takes more time per degree of rotation.…

    fMRI scans done by Kanwisher et al. (1997) showed that the fusiform gyrus in the brain was more active in face recognition than object recognition, this suggests and supports the idea that face recognition involves a separate processing mechanism. This model suggests that we process familiar and unfamiliar faces differently. That we process familiar faces using; structural encoding, FRUs, PINs and Name Generation. However, we use structural encoding, expression analysis, facial speech analysis and direct visual processing to process unfamiliar faces.…

    The study chosen is called Cultural Differences in the Perception of Geometric Illusions. The research specifically focused on the psychological processes of depth perception and visual perspective. The first example is the Muller-Lyer illusion which is an optical illusion consisting of stylized arrows in which viewers tend to perceive one as longer than the other. The second example used is the Sanders Parallelogram in which a diagonal line bisecting the larger, left-hand parallelogram appears to be slightly longer than the diagonal line bisecting the smaller, right-hand parallelogram, but it is in fact the same length. The last example used in the stimulus is the horizontal-vertical illusion, in which observers have the tendency to perceive the vertical as longer than a horizontal line of the same length when the lines are perpendicular. All of these relate to how a subject is able to understand the spatial qualities. The researchers hypothesize that the cultural differences between the people tested affect their perception of the lines.…

    Case (2) is also cognitive, even though it is a physical rotation and not mental rotation like case (1) and (3) it is not fundamentally different. Since with the rotation button, case (2) displays the same sort of computational structure as case (3). The difference between case (2) and (3) is that the computational structure is spread across the person and the computer, case (2) being external while case (3) is internalised within the person. If case (3) is similar to case (1) and the rotating of the shapes is through the neural implant still counts as a cognitive process, then there is no reason of denying that the rotating method in case (2) would also count as a cognitive process, or as part of a cognitive process. As previously stated, the computational structure in case (2) is the same as case (3) and although in case (3) the computational structure is internalised within the person, nothing else of significance seems different according to Clark and…

    The following study does a replication of Cooper and Shepard’s (1973) study on mental rotation using rotated and normal stimulus. The study investigated the effects of degree of rotation of the stimulus on the time taken (RT) for participants to distinguish between inversed stimuli and non-inversed stimuli. In the following study, we used 2 normal stimuli and 2 inversed of the normal stimuli, and applied 19 levels of angular rotations ranging from 0 degree to 180 degree. Fifty-five participants took part in the following study, and everyone was briefed on the purpose of the experiment. The design of the following experiment used a within-subjects design where everyone did the same experiment in the same computer laboratory and received the same set of instructions. The pictorial stimuli ran on experiment software, and participants were required to provide keyboard response. It was revealed that participants so apply mental rotation while working with inversed and rotated stimuli, and that the higher the angular rotation, the higher the RT of participants. This supports Cooper and Shepard’s findings.…

    Face perception is the process by which the brain and mind understand and interpret the human face. The cognitive and neural processes in face recognition differ greatly from those observed for object recognition. Both objects and faces are generally considered to be “viewpoint-dependent” meaning that performance in recognition is better when viewed from a familiar viewpoint. However when considering Biederman’s (1987) recognition-by-components theory he found that objects can be recognised equally as easily from all viewpoints. This is due to his belief that objects are recognised from the individual basic shapes that make the whole object; these are called “geons”. Recognition of an object occurs when the stored representation of an object best fits the geon based information. However according to Bruce and Young (1986) face recognition starts with the visual encoding of the features of a face, meaning that one is able to identify a face viewed from any angle through its features as identified in their model for face recognition. Whilst cognitive and behavioural processes are involved for face and object recognition, and said processes vary greatly between the two, there are also important neural processes involved in face and object recognition. Particularly the role of the Fusiform face area for face recognition and the role of the inferotemporal cortex for object recognition. Other psychologists explain the different recognition processes between face and object recognition through the theory of expertise, whereby face recognition does not have face specific processing but is due to individuals having a greater expertise at individuating faces. Diamond and Carey’s (1986) study aims to support the expertise hypothesis by showing that experts process their objects of expertise in the same way as faces, therefore supporting their hypothesis that it is not due to…

    Experiences we encounter every day would make us believe the accuracy of our sensory perception. At Shoppers Food Warehouse during the holiday season, I saw a man who kept staring at me. He looked familiar but I couldn’t place his face. A while later while we were checking out, he said to me “You don’t remember who I am, do you?” I apologized for not knowing his name, even though I had said hi to him. He then told me his name and after that I remembered him being the brother of a friend of mine. The reason I did not recognize him at first as the fact that he was…
