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

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

acid-catalyzed hydrolysis reaction. For the purpose of this lab‚ it is quite useful to fully understand the following terms: optical rotation and carbohydrate. Optical rotation is measured by a polarimeter‚ which measures the polarization of light and the rotation of polarized light (influenced by enzymes). It is dependent on the concentration of sample‚ temperature‚ length of the tube and the observed rotation. The +/- degrees of the optical rotation determines the presence of d- and l- enantiomers.

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

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

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

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

What new knowledge and/or skills did you learn during this rotation? In what ways has this learning changed your perspective on this particular field/career? I learned how to diagnose a patient‚ different exercises‚ and ways to see how long their treatment will last. I learned what muscles work together and how to tell which one is lacking strength. I learned a lot more about how the body parts work together and why treatment is necessary for people. I thought that Physical Therapists just were

Prepared by Dan MacLeod and Eric Kennedy 1993 Introduction There are many reasons for implementing a job rotation system including the potential for increased product quality‚ employee satisfaction and lower cumulative trauma disorder rates. However‚ the difficulties of changing the organizational structure of an entire facility can prove difficult. It is important that the program start slowly at first so that the program can
