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.     

DIMENSION ANALYSIS OF THE PERCEPTION OF INSTRUMENTAL TIMBRE

W edin L. & G oude G. Dimension analysis of the perception of instrumental timbre. Scand. J. Psychol ., 1972, 1 3 , 228–240.—The dimensionality of the perception of instrumental timbre for single tones was investigated through multidimensional scaling according to Ekman's vector model of similarity. Three factors were extracted and they were identified with certain characteristics of the spectrum envelopes. It was found that initial transients were important for the identifiability of instrumental tones but their presence or absence did not influence the dimensional structure. The "perceptual structure" was found to be different from the "cognitive structure" (= knowledge about the classification of the instruments), and the results are general for both trained and naive listeners.     

APPROACH AND WITHDRAWAL IN YOUNG OF TILAPIA MOSSAMBICA (CICHLIDAE, PISCES) AS A FUNCTION OF AGE AND SOCIAL EXPERIENCE

G oude G., E dlund B., E ngqvist -E dlund U. & A nderson M. Approach and withdrawal in young of Tilapia mossambica (Cichlidae, Pisces) as a function of age and Social experience. Scand. J. Psychol ., 1972, 13 , 89–97.—In an experiment with eight groups of young of Tilapia mossambica , approach and withdrawal behavior was registered during brief (5 min) periods of stimulation with a moving dummy; the experiment lasted twelwe days (towards the end and immediately after the sensitive period). Four of the groups comprised young which had been isolated from each other until the first stimulation period; in the other four groups the young had been kept together in the experimental tanks. The age of the young when first stimulated was varied experimentally. Changes in approach and withdrawal behavior over time were studied along with e.g. changes in group strength. Age at first stimulation was found to be of some consequence but no clear differences were obtained between groups with different environmental experiences.
