    Effects of degree of rotation 012687 University of Nottingham Malaysia Campus Abstract 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

    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

    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

    Mental Rotation Lab Report: PSY 405 – Spring 2012 Deng Jichun Introduction The purpose of this experiment was to confirm the theory that we create picturelike representation of perceived visual stimuli‚ and we can also mentally rotate the representation to a known “upright” position. The reaction time increases linearly according to the angle of the rotation‚ regardless of their complexity (Cooper‚ 1975). In some circumstances‚ we snap the perceived visual stimuli and create

    Abstract The idea of mental imagery has always been a controversial subject in the field of psychology. Many psychologists have argued that such a concept is impossible to measure because it can not be directly observed. Though they are right about this‚ it is not impossible to measure how quickly mental rotations of images are processed in our brains. Subjects in this experiment were presented two shapes simultaneously‚ via computer screen‚ and asked to make judgement‚ as quickly as possible

    Gender Differences in Mental Rotation Abstract The general research topic for this were the sex differences in mental rotation. Twenty- five female students and five male students were assigned to different treatment conditions and were tested on their response time and accuracy in the different mental rotation conditions. It was hypothesized that lateralization between genders would effect the results based on stimulus type. Males were expected to perform better‚ both in accuracy and speed

    figures. One way in which spatial ability can be operationalised is in the form of mental rotation test. A mental rotation test requires participants to identify rotated versions of a target stimulus. Mental rotation usually takes place in the right cerebral hemisphere‚ in the areas where perception also occurs. Mental rotation can be separated into the following cognitive stages (Johnson 1990): 1) Create a mental image of an object 2) Rotate the object mentally until a comparison can be made 3)
