Boundary regulation in family and personal systems: Perceptions of late adolescents

Examination of boundary regulation can provide family therapists with a framework to describe both the functioning of family systems and personal systems (i.e., the intrapsychic functioning of individual family members). In the present study, late adolescents' perceptions of boundary regulation within their family systems (i.e., ratings of family health, communication, leadership, expressiveness, cohesion, and family conflict) were related to regulation of their personal boundaries (i.e., self-reported personal competence, distress, and patterns of defense mechanism use). In addition, personal system variables reliably discriminated between adolescents who described their families as psychologically healthy versus psychologically unhealthy.     

Are attentional dwell times inconsistent with serial visual search?

Duncan, Ward, and Shapiro (1994) estimated that attention must remain focused on an object for several hundred milliseconds before being shifted to another object, and they referred to this period as theattentional dwell time. An important implication of these long estimates of the dwell time for models of visual search is that the search process must not involve an item-by-item serial scanning mechanism. If it did, then searching through an array of items would require enormous amounts of time, which—based on data from visual search experiments—it does not. The present report, however, provides evidence that the long estimates of attentional dwell time were caused, at least in part, by the use of masked targets. Implications of these variable estimates of the attentional dwell time for models of visual search are discussed.     

Validation of the Children's Assertive Behavior Scale

Relationships between sociometric indices and scores of 160 elementary-school children on the Children's Assertive Behavior Scale (CABS) were examined to determine whether this instrument differentiates children of varying levels of social competence. Children who obtained either high or low scores on peer nominations of friendship and admiration were identified and compared on CABS passive, aggressive, and assertive scores. Children who scored high on positive peer nominations responded in a significantly less aggressive manner than children who received low scores on such nominations. These effects were observed for the CABS format that consisted of stimulus situations involving adults but not for the form involving peers. With regard to responses toward peers, a significant interaction between sex and sociometric status emerged. These findings suggest the importance of incorporating subject variables such as race and sex as well as assessments of behavior toward both adults and children in isolating and training components of social skill.The authors wish to express their appreciation to Jean Birbilis, Gail Hammersly, Marieta Knopf, and Donna Wadley for their assistance in data collection and analysis.     

Depth of processing: When the principle of congruity fails

Two factors, level of processing (Craik & Lockhart, 1972) and congruity (Schulman, 1974), known to have large effects on the recall of experimenter-provided responses to questions, were examined in a series of five incidental learning experiments using subject-generated responses. The data show that manipulation of level of processing has the same effect on recall of subjectgenerated responses as it does on experimenter-provided responses. However, the effect of congruity is reversed for subject-generated responses. The data suggest that the difficulty of generating unrelated responses (“incongruous“ items) may account, at least in part, for the failure of the “principle of congruity“ with subject-generated responses.     

The effect of couples training and partner co-operativeness in the behavioral treatment of obesity

To evaluate the influence of spouse co-operativeness and couples training in the treatment of obesity, 29 obese men and women were assigned to three experimental conditions: (1) Co-operative spouse-couples training: subjects attended all meetings with spouses. Spouses were trained in modeling, monitoring, and reinforcement techniques; (2) Co-operative spouse-subject alone: subjects attended meetings alone even though their partners had agreed to become involved in treatment; (3) Non-cooperative spouse: subjects had spouses refusing to participate in the program, and attended sessions alone. At the 3-month and 6-month maintenance assessments. subjects in the spouse training condition lost significantly more weight than subjects in the other two conditions. Weight losses compared favorably to those of any controlled study with subjects in the couples training group averaging nearly 30 lbs lost after 8$\text{1}\text{2}$ months of treatment. In the absence of spouse training, subjects with co-operative spouses did no better than subjects with non-co-operative spouses. The findings suggest that spouse training may have a potent facilitative effect in weight reduction, and that this effect may promote long-term maintenance of weight loss.     

Feedback modalities as a consideration in biofeedback applications

Effects associated with specific feedback modalities are neither clear nor well explored. The present paper provides an overview of feedback modalities typically used for the presentation of information from major physiological systems. Some consideration of feedback modality in relation to theory is provided with a discussion of trends in past applications.     

A system for the assessment of human performance in concurrent verbal and manual control tasks

A multipurpose laboratory system incorporating a voice interactive terminal and graphic display system is described. The facility is designed to investigate some aspects of human performance on concurrent verbal and tracking tasks. The results of a pilot study showing decrements in dual-task performance are reported.     

Learned helplessness and the schedule-shift hypotheses

The critique of learned helplessness research and theory and the alternative schedule-shift discrimination hypothesis offered by McReynolds (Journal of Research and Personality, 1980,14, 139–157) are considered. Each point made by McReynolds is discussed and a variety of recent experimental evidence is reviewed. It is concluded that McReynolds' critique is without substance and that the schedule-shift discrimination explanation of the learned helplessness effect is contradicted by existing data.
