Toward an objective evaluation procedure of the Kinetic Family Drawings (KFD).

The feasibility of employing a quantitative scoring procedure for evaluating the Kinetic Family Drawings (KFD) was examined. A quantitative scoring procedure was developed from the clinical hypotheses Burns and Kaufman (1970, 1972) to score 21 measurable KFD styles, actions, and characteristics. The scoring procedure was employed to evaluate 116 KFDs obtained from four groups of boys to determine the effectiveness of the procedure to differentiate among two levels of emotional adjustment and the two levels of age. The results indicated that four of seven sets of extracted component scores significantly differed between the emotionally well-adjusted and the emotionally disturbed groups. One set of component scores significantly differed between the younger and the older groups, while two sets of component scores did not differ among any of the four groups. The KFD total score was found to differ significantly only between the young emotionally disturbed and the young emotionally well-adjusted groups. It was concluded that a quantitative scoring procedure for the KFD is feasible.     

Polarizing effects of social comparison

Does exposure to others' judgments merely elicit conformity to what is observed? Two experiments are reported in which people who were merely exposed to others' responses tended not to conform to the average observed response but to exceed it in the socially preferred direction. These experiments complement social psychology's historic emphasis on conformity by suggesting that not only do people avoid being markedly deviant from others; they also act to differentiate themselves from others toward the extreme that reflects the group ideal.     

Conditioned fear extinction and reinstatement in a human fear-potentiated startle paradigm

The purpose of this study was to analyze fear extinction and reinstatement in humans using fear-potentiated startle. Participants were fear conditioned using a simple discrimination procedure with colored lights as the conditioned stimuli (CSs) and an airblast to the throat as the unconditioned stimulus (US). Participants were extinguished 24 h after fear conditioning. Upon presentation of unsignaled USs after extinction, participants displayed significant fear reinstatement. In summary, these procedures produced robust fear-potentiated startle, significant CS+/CS- discrimination, within-session extinction, and significant reinstatement. This is the first demonstration of fear extinction and reinstatement in humans using startle measures.     

A study of grouphate in a course on small group communication

This study explored the relationship between grouphate and cohesion, consensus, relational satisfaction, affective learning, and cognitive learning. Participants were 83 undergraduate students enrolled in an introductory course on small group communication. Participants completed the Grouphate scale, the Classroom Cohesion scale, the Consensus scale, the Relational Satisfaction scale, three subscales of the Instructional Affect Assessment Instrument, and the Cognitive Learning Loss measure. Mean grouphate significantly increased during the semester, and negative correlations were found between scores for grouphate and cohesion (-.50), consensus (-.45), relational satisfaction (-.58), attitude toward the behaviors recommended in the course (-.23), the likelihood of developing an appreciation for the course content (-.33), and cognitive learning (-.32). Results may imply that students' grouphate is not associated with prosocial outcomes of the group work in this course.     

Short-term recognition memory of tones

Four Os participated in a recognition memory experiment for a period of 5 weeks. The task required O to judge whether two temporally sequenced tones (ISI = 0.5, 2.0, or 8.0 sec) were the “same” or “different ” Latencies and confidence ratings were obtained for each judgment. TSD analyses applied to individual O’s data indicated consistent and rapidly decreasing d’s as a function of ISI. ROC functions generated from the latencies and ratings produced comparable results, indicating the feasibility of using latency measures along with the type of judgments made to obtain sensitivity measures. Response bias, as indicated by the differences in the latencies between “same” and “different” judgments, did not produce consistent trends.     

Perceptual capacity of the isolated visual cortex in the cat

The split-brain approach was utilized in 6 cats to test the degree of functional autonomy in the visual system. The central visual cortex of one hemisphere was isolated by the removal of most of the extravisual neocortex of the same hemisphere. Visual inflow was restricted to the isolated side in four cases by sectioning the crossed optic fibres at the chiasma and masking one eye and in two cases by section of the contralateral optic tract. The isolation produced severe deficits in visual performance, although all cases retained some ability to learn and to recall simple pattern discriminations. The results of two- and three-stage removals of the non-visual cortex, and of terminal section of the callosum, as well as histology of the lateral geniculate nucleus indicated that geniculo-striate damage was not the limiting factor. Removal of fronto-parietal cortex produced as much or more decrement in visual discrimination than did removal of temporal cortex.
