The effects of a model's success or failure on subsequent aggressive behavior

It was of interest in the present study to examine the influence of both aggressive and nonaggressive models who are successful or nonsuccessful in reducing aggression from an aggressive opponent. Male and female subjects viewed a same-sexed model interact with an aggressive opponent in a reaction time task. Half the subjects observed an aggressive model while the remaining subjects observed a nonaggressive model. For half the subjects the model was successful in reducing the aggressiveness of the opponent. Results indicated that both the model's behavior and the consequences to the model (success/nonsuccess) were important determinants of subsequent aggression by the subject. Results are discussed in terms of current research and theory in aggression control.     

Hope of success and fear of failure components of Mehrabian's scales of resultant achievement motivation

This report is concerned with the factor structure and psychometric properties of the nonprojective Male and Female scales of Resultant Achievement Motivation (RAM) developed by Mehrabian (Educational and Psychological Measurement, 1968, 28, 493–503). The 26-item self-report scales along with Mandler and Sarason's (Journal of Abnormal and Social Psychology, 1952, 47, 166–173) Test Anxiety Questionnaire (TAQ) were administered to 237 males and 225 females in Experiment 1. Unrestricted maximum likelihood factor analyses of the RAM scales revealed four primary factors for each version. Since the first two factors from both analyses resembled measures of Hope of Success and Fear of Failure, two strategies for improving the scales were adopted, both of which eliminated the items loading on factors III and IV. One strategy involved adding the indexes of Hope of Success and Fear of Failure, while the other involved finding their difference. Construct validity coefficients were computed for the 26-item full scales, and the RAM measures formed using the above strategies with student grade point average and TAQ scores as the criterion variables. In Experiment 2, the appropriate RAM scale and the TAQ were administered to 30 males and 38 females. Construct validity coefficients were computed in this cross validation sample with the three RAM measures as predictors and with TAQ scores and student achievement in a course in Social/Personality Psychology as the criterion variables. The three RAM measures were used to predict the performance of 16 males who worked at a common laboratory task (anagrams) in Experiment 3. The results of all three experiments indicate the Hope of Success minus Fear of Failure measure to be the best measure of RAM from a theoretical, psychometric, and pragmatic point of view.     

Assessment of children's social skills

Various methods of social skills assessment with children were reviewed. Based upon an extensive review of the literature, it was found that behavioral observations, sociometrics, and teacher ratings have been the most often used methods of assessing children's social skill deficits. Advantages and disadvantages of each assessment technique were discussed within a psychometric and social validation context. Conclusions were that school psychologists should utilized all three measures to secure a comprehensive picture of children's social behavior and to obtain some measure of social validation.     

Effects of age,stimuli, and category recognition factors in children's inquiry behavior

One hundred twenty-eight children of average intellectual ability from grades K, 1, 2, and 5 (ages 6, 7, 8, and 11, respectively) were administered a 20-questions task involving the presentation of 24 stimulus pictures and a forced-choice post-test. The four-factor design included four grade levels, two stimulus conditions (basic-level and superordinate), and two instruction conditions (cueing and non-cueing) for boys and girls. Results indicated older children generated more efficient questions, all children in the Cued-instruction condition asked more constraint-seeking questions in the Basic-level condition than in the Superordinate condition on the 20-questions task, and all children in the Basic-level condition selected more efficient questions in the post-test forced-choice task than in Superordinate condition. It was concluded that even younger school-age children will generate efficient constraint-seeking questions when Basic-level stimuli are used and when children are cued.     

Qualitative aspects of pantomime recognition defect in aphasia

This study investigated the performance pattern of aphasic patients on a pantomime recognition test in which one of the four response alternatives was an object semantically related to the correct choice. Aphasics with defective pantomime recognition made 71% of their total errors on the semantic foils, and for the majority of such patients, semantic errors represented 80 to 100% of total errors. Only aphasies with objective evidence of confusion failed to make highly frequent semantic errors. The findings suggest that most aphasies who fail pantomime recognition are impaired because of semantically vague understanding of the pantomimes' intended meaning rather than complete lack of understanding of the pantomime.     

Hemispheric asymmetry in memory search for four-letter names and human faces

Two memory search experiments were conducted using vertically oriented four-letter names and human faces as stimuli. Subjects were required to indicate as quickly and as accurately as possible whether or not a single probe stimulus (presented for 150 msec to either the left or right visual field) was contained in a set of 2, 3, 4, or 5 items being held in short-term memory. The probe stimuli were presented alone (clear condition) or centrally embedded in a matrix of dots (degraded condition). In Experiment 1 (involving names), a right visual field/left hemisphere advantage was obtained and pinpointed at the encoding stage rather than at the memory comparison stage of the information-processing system. For Experiment 2 (involving human faces), no hemispheric advantage was readily observed. In each experiment, both the left hemisphere and the right hemisphere employed an abstract memory comparison operation from which the effects of probe degradation have been removed. These results are discussed in terms of their implications for various models of hemispheric asymmetry.
