Easterbrook's Hypothesis And Eyewitness Cue Utilization, Mark R. Hill
Easterbrook's Hypothesis And Eyewitness Cue Utilization, Mark R. Hill
Master's Theses
Although well-supported and historically-important, the Yerkes-Dodson research cannot incorporate current findings on the relationship of arousal and selective attention. Easterbrook's hypothesis suggests that arousal produces a narrowing of attention which selects among available stimuli. Whether information is processed depends on the level of arousal and the nature of the task. As arousal increases, Easterbrook predicts more attention directed to central tasks, while superfluous stimuli are progressively removed. The present investigation studied the predictions of Easterbrook' s hypothesis on.incidental memory in a simulated eyewitness case. College students were aroused to either resting, 50, 65, or 85 percent maximum heartrate by their …

The Effects Of Positive And Negative Mental Rehearsal Upon Adolescent Boy's Performance On Mirror Drawing, Jeffrey Alan Betman
Master's Theses
Forty-five adolescent males were divided into three groups of imagery ability based on Marks' Vividness of Visual Imagery Questionnaire. Within the groups of low, medium, and high ability each subject was randomly assigned to one of three mental rehearsal conditions: positive mental rehearsal, negative mental rehearsal or neutral mental rehearsal. Subjects were given the appropriate mental rehearsal instructions and then completed a mirror drawing task. A 3 x 3 (ability level x type of instructions) analysis of variance was performed on the number of errors and elapsed time for the mirror drawing task. Although specific hypotheses had been predicted no …
Locus Of Control And Attribution As Predictors Of Learned Helplessness In Children, Anne Marie Albano
Locus Of Control And Attribution As Predictors Of Learned Helplessness In Children, Anne Marie Albano
Master's Theses
The present study investigated the predictive value of locus of control and internal-external attribution as they relate to learned helplessness in children. Forty four females and twenty seven males enrolled in the fifth and sixth grades of a private elementary school served as subjects. Subjects were group administered the Nowicki Strickland Locus of Control Scale for Children and the KASTAN Attribution Rating Scale. They were then exposed to a guessing task designed to induce helplessness, and subsequently tested on a persistence task. It was expected that subjects would differ in persistence time based upon their internal-external locus of control orientation, …
