The Importance Of Learning More About Linear Regression, We Have Replicated Shepard And Metzler's Original Mental Rotation Experiment

The experiment took place in room 337, the experimental psychology lab room in the science building of Queens College, CUNY.

In experiment 1, participants were instructed to press a key to determine if the stimulus was red, blue, yellow, or green. On the second half of the experiment, the stimulus appeared in grey with only one colored letter which was positioned randomly. Error rates for the experiment were below 2.5% for each condition, which is quite low. Experiment 2 was the same as experiment 1 except that there were 114 data collections instead of 288 and there were 36 practice trials instead of 72. According to experiment 1 and 2 it is suggested that the effect of

The equipment used consisted of a 60 Hz monitor on a 19 – inch computer screen. The program for the test ran on a viglen Pentium 4.30 GHZ. To present the stimuli’s four

The trials for each of the six conditions were presented in a random order. The experimenter controlled for differences among participants by having them set their own equiluminant point for the cue stimuli and eliminated luminance differences by embedding the stimuli in a random luminance noise. The experimenter also controlled for outliers by eliminating response

This study was a seminal replication on attention blink similar to the one done by Raymond et al, in a rapid serial visual presentation (RSVP) task. This study predicted that there would be a higher accuracy for identifying the first target, T1 and lower accuracy for the second target, T2 depending on the lag, given that T1 was accurately reported. 193 students participated in the experiment. This experiment was a part of the course requirement. There was a stream of 19 letters, each lasting for 100 ms. The target letters, T1 and/or T2, to be identified were either a ‘J’ or a ‘K’ or both from the stream of 19 letters presented. In this study, a total of 60 trials were conducted for each participant. For T1, there were 30 ‘J’ and 30 ‘K’ targets. T2 comprised of 24 J, 24 K and 12 null targets. The participants were asked to decide whether they saw the letters J, K, both or neither following the RSVP stream. They were asked to do so by using a button click mechanism. At the end of all the trials, the participants were presented with a summary of their performance report. It was observed that the percentage of T1 reported does not vary significantly as a function of lag. Also, the percentage of T2 reported varied as a function of lag. At greater lag positions, it was seen that the percentage of T2 reported goes above that of T1.

The experiment consisted of 6 trials that contained words such as: sleep, bed, tired etc. The participants were asked to look at the rectangle on the screen before starting the trials. In the first trial, the participants were asked to press the “start trial” button because a fixation dot would appear in the middle of the screen. The participants were asked to stare at the computer until a sequence of words appeared, with each word was presented for one second. After a full sequence was presented, a set of buttons were shown, each labeled with a word. Some the words were on the list, and some were not. The participant’s task was to click or tap on the buttons to indicate which words were in the sequence. The sequence of words consisted of the actual words shown or related or unrelated words. For example, some trials consisted of all sleep related content to see if the participant would select items that were related or select items that were not in the sequence. After identifying the words that were shown in the sequence, they would receive feedback on the accuracy of their memory. After the participants were done

The results found from this study show that there was a significant difference in performance based on whether the task was done in the binocular or monocular condition. Participants performed significantly faster in the binocular condition compared to the monocular condition. Similarly, participants had significantly less errors in binocular condition in contrast to the monocular condition. This result is in accordance with previous research that found participants performed better with binocular viewing in a multitude of tasks (Read et al, 2013). This result also supported the theory that performance would be better with binocular viewing rather than monocular viewing.

The VideoToolbox and PsychToolbox extension of the application MATLAB were used to produce the stimuli using an Apple Mac Mini (OS X) computer, while A 17-in. Viglen VL905T CRT monitor with a resolution of 1,024 x 786 pixels and a refresh rate of 100 Hz, was used to display the stimuli. Results in the form of accuracy and reaction time were gathered using a standard QWERTY keyboard, while the experiment itself took place in a consistently darkened room, while the participants sat in an adjustable chair at a distance of 60 cm away from the screen.

Similarly, both theories are supported by research. Lawson and Humphreys (1996), for example, showed that recognition is affected more by tilt of major axis (foreshortening) than any other rotation, which endorses Marr’s and Nishihara prediction that establishing a central axis is crucial to the process of recognition. Warrington and Taylor (1978) reported that brain damaged patients could recognize objects presented in a typical view only. These patients found difficult to say if two photographs presented simultaneously were the same object when one image was a typical view and the other an unusual view. Although this could be explained as the patient’s inability to transform a 2D version of the atypical view into a 3D model, it could also be due to difficulty in establishing the central axis or due to some features of the object being hidden. In a later study, Humphreys and Riddoch (1984) used images where either the axis had been foreshortened through rotation or a critical feature was hidden. They found that patients had more problems recognizing the images with a foreshortened axis than the ones where a critical feature was hidden. Their

The experiment consisted of three tasks. The first task differed based on the condition, where participant was asked to either passively look at the pictures, rate how the pictures are related to a similar set of pictures presented alongside the trial image, or to locate an action within the picture. In all cases, the participant viewed emotional images. The second task, a distracting task, consisted of calculating two simple math sums (e.g. 8-3) and deciding which one is larger. The last task was a recall of all trial pictures seen
