Psychology

The following are some papers and studies that I wrote as part of a course requirement.

Aggressive and Prosocial Events on Children’s Television Shows
March 27th, 2007
Abnormal Child Psychology (PSYO 3091)

This study had a few restrictions on it that the others didn’t have. An abstract wasn’t required and I think there was a word limit of 1200 words.

Organizing Objects Based on Physical Characteristics and Origin:
Can 3-year-olds do it?

Mere-Exposure Effect on Judging Mirror vs. Actual Images
December 4th, 2006
Experimental Social Psychology (PSYO 3082)

Abstract
It has been found that people prefer their mirror image over their actual image due to the mere-exposure effect (Mita, Dermer & Knight, 1977). Zajonc (1968) theorized that people prefer things that they are exposed to more often. The present study has 30 participants that chose between a mirror image or an actual image of themselves and of a randomly selected partner. The results confirm a null hypothesis for choosing the mirror image of the self over the actual image (p-value = 0.6293) but reject the null hypothesis of choosing among the images of others (p-value = 0.0314), as two thirds of the participants chose the actual image of the partner. Future studies could take into account confounds of the control of the setting in the present experiment and also introduce the idea of choosing between images in motion instead of still images.

Visual Cues, Landmarks and Time and How They Aid Object Permanence

Cognitive Psychology (PSYO 3390)

The purpose of this paper was to design a study based off of a previous one.

Attractiveness and Trustworthiness: Is there a Connection?
November 20th, 2006
Experimental Social Psychology (PSYO 3082)

Abstract
Much effort is put into enhancing the features of attraction, as being attractive is beneficial in many aspects of everyday life. The present study compared ratings for smiling and neutral photos of 15 women under attractiveness and trustworthiness conditions. The results showed that there was a significant correlation between attractiveness and perceived trustworthiness (r = 0.41) among all of the faces for the two conditions. It was concluded that, since ratings under both conditions were higher for smiling faces than neutral faces, that smiling is a positive factor toward appearing both attractive and trustworthy. Future studies could use photos of unfamiliar faces to determine whether the results would support the present data.

Magnitude Estimation of Length, Area and Brightness
October 5th, 2006
Cognitive Psychology (PSYO 3130)

Abstract
Estimating a change in the property of an object involves the use of the short-term memory in a process studied by Hartley (1977). The present experiment compared a standard in three conditions of length, area and brightness to twenty trials at the beginning of each condition. The results showed the highest accuracy for magnitude estimation for line length while not showing as high estimation for both area and brightness. Due to the standard being presented just once at the beginning of each condition, it was clear that the short-term memory did not store the standard for a long period of time but that it compared each trial to its predecessor.
