Effects of BIM-22015, an analog of ACTH4-10, on functional recovery after frontal cortex injury.

Male rats, 90-100 days old, with frontal cortex lesions were given either subcutaneous sterile water (SW) as a vehicle control or 1, 10, or 100 micrograms of BIM-22015 every other day for 20 days. Brain-injured subjects tested in the Morris water maze with either 10 micrograms BIM-22015 or SW took significantly more trials than sham-operated rats to locate a submerged platform eight consecutive times within 60 s. The animals given 1 or 100 micrograms BIM-22015 took significantly fewer trials to reach criterion than brain-injured animals in the other drug treatment groups. On a percentage of savings, measured 8 days after reaching criterion, the brain-injured subjects given 1, 10, or 100 micrograms BIM-22015 did not differ from sham-operated rats. In contrast, the brain-injured animals given SW took longer to find the submerged platform than they did during the initial training. To assess long-term effects of the ACTH analog treatment, rats were trained on a delayed spatial alternation task 30 days after receiving the last injection. On this task, brain-injured rats treated with the 10-micrograms dose performed significantly better than those given sterile water. Acetylcholinesterase (AChE)-labeled neurons counted in the nucleus basalis magnocellularis indicated that rats with frontal cortex damage given the 10-micrograms treatment did not differ from the sham controls and had significantly more AChE-positive neurons than injured counterparts treated with SW or 100 micrograms.     

A Self-report Family Data Form for family therapy

Family therapies which aim to begin treatment in the first session leave the practitioner at a disadvantage regarding the collection of demographic, historical, and genealogical data that may be useful as treatment proceeds. Not wanting to disrupt interactional reciprocity and flow, the therapist cannot perform methodical anamnesis. The Self-report Family Data Form is presented for collecting useful biographical data from families in treatment without interfering with the clinical interaction.     

Identifying emergent leaders from verbal and nonverbal communications.

Subject/observers were accurate in identifying emergent leadership hierarchies on four leadership dimensions when provided records of target groups' meetings containing only verbal communications, only nonverbal communications, or both types of behavior. With knowledge of participation rates controlled by covariance, the subject/observers' accuracy scores retained significance in three of the information conditions demonstrating the presence of verbal and nonverbal leadership cues independent of participation rates. The value of verbal and nonverbal communications to identifying leaders varied with the type of leadership hierarchy being identified. The findings are presumed to hold for leader selection as well. The author proposes that the question of why a group member has emerged to fulfill a leadership role in a group be studied from the point of view of group members' selecting leaders or permitting emergence rather than leaders emitting behaviors.     

Decisions of timing in experimental probabilistic duels

The paradigm of the 2-person, zerosum, infinite game as a model of bipolarized conflicts in real time is extended to the probabilistic duel, where a player does not know with certainty whether or not this opponent is armed, but only knows the probability of such armament. Twenty dyads participated in a computer-controlled probabilistic duel experiment, ten of them playing a noisy version (where all bullets fired are public knowledge) and ten playing a silent version (where unsuccessful fire is unknown to the opponent). Several game-theoretic implications were tested, some of which demonstrate the efficacy of the theory of games of timing as an explicatory mechanism for decision behavior in experimental duels.     

Attitudes toward women among female college students

Female college students' attitudes toward women were investigated to determine the effects of housing, class status, and general field of study, and to provide standardization and reliability data for the AWS scale. Spence and Helmreich's Attitudes Toward Women Scale was administered to a large sample of female college students in a coed, moderately sized, private, Eastern secular college. Results indicated that seniors tend to hold more liberal attitudes toward women than underclasswomen and students in Business and Education tend to hold more conservative attitudes toward women. Interaction effects were observed and reported. Type of housing was not related to attitudes toward women. The split-half reliability technique revealed a strong internal reliability of .92 for the AWS.
