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)

study the effects of hand preference on mental rotation. We did so by conducting an experiment where half of the participants were asked to use their dominant hand to respond to images rotating at one of four degrees or to use their non-dominant hand. I hypothesize a main effect for angle and hand dominance as well as interaction between the two variables in effecting the response time as well as the accuracy rate. In an experiment on the mental rotation of three dimensional objects conducted

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, as

when making a judgment about the nature of mental representation of an image; they were also unique in their abilities in that each participant was capable of completing a different number of trials. Reaction time also varied among individuals in both same-data (figure 3) and mirror-date (figure 4). The data from the experiment provided supporting evidence for our hypothesis, which states that reaction time would increase as a function of the angle of rotation for which the three-dimensional

Prep for Mental Health Rotation: Multiple Personality Disorder Multiple Personality Disorder (MPD) is a severe condition in which a person has two or more distinct identities or personality states. This disorder can take control of an individual. MPD is a disorder characterized by identity fragmentation rather than a development of separate personalities. The disturbance is not due to the direct psychological effects of a substance or of a general medical condition (Dissociative Identity Disorder)

performance on angle of rotation and shape in mental rotation tests, as tested and discussed in past studies such as Masters (1998). Mental rotation tests were first introduced by Shepard & Metzler (1971). Visual imagery and mental rotation have great relation. According to Shepard & Metzler (1971) mental rotation is when humans visually image two dimensional stimuli and are able to rotate them in their mind. According to the mental rotation section in CogLab On A CD, everyone has mental imagery. Moreover

The time to respond an object while imagining it in rotation: The subject is instructed to imagine an object being rotated in certain direction. During this process of mental rotation subject is presented with a test object and the subject has to tell whether the object is standard or reflected. Cooper and Shepard conducted an experiment where a character was represented in 6 different orientations according to the auditory command. When the object was represented in same orientation as to the auditory

THE INFLUENCE OF GENDER ON THE NUMBER OF CORRECT ANSWERS ON THE MENTAL ROTATION TASK Introduction Gender is known to be one of many variables, which has been discovered to influence cognitive performance. Cognitive gender differences are defined as average differences in performance between females and males on tests of academic achievement and cognitive abilities (Miller & Halpern, 2014). Additionally, different cognitive tasks are recognised to favour different gender. While males typically

different images (whether one can be turned into the other by a rotation). The participant clicks a button to specify whether the images are the same or different. RESULTS The results of this experiment are the mean reaction times that it took the participant to decide whether the example they where presented with was the same or different object. The means of both of the sets of data clearly shows that as the angle of the rotation of the object increases the reaction time of the participant
