Assaultive behavior resulting from marital conflict

Recent evidence shows that dangerous acts, especially serious ones, are highly likely to be directed against family members. This fact calls for interpersonal assessment of dangerous behavior. The present authors have undertaken preliminary study of fighting behavior (verbal and physical) between married couples. A semistructured interview procedure has been devised to establish the methods used by both partners in carrying on their disputes. The authors propose that there are three broad types of fighting patterns to be found:constant high—sustained level of balanced antagonism;unpredictable volatile—low level of overt antagonism with occasional difficult-to-predict highly violent episodes;steady escalation—increasing levels of violence over time. Data from one couple representing each pattern are presented to demonstrate different parts of the interview schedule.     

Gender Role of Male Therapists in Both Professional and Personal Life

This study's purpose was to extend the distantresearch on gender roles. The specific objective was tobetter understand the gender role of male psychologists.It was hypothesized that male psychologists would exhibit an androgynous gender role.Gender role styles in professional work and in thepersonal realm were assessed. Questionnaire packets weremailed to 300 male clinical psychologists affiliated with the American Psychological Associationacross six regions within the United States. Sixty ofthe 61 participants reported being Caucasian and 1reported being Native American. Being that the sample was that of practicing psychologists, all withdoctorate degrees, the social class is presumed to be atleast upper middle class. The packets contained ademographics questionnaire and two Personal Attributes Questionnaires. Results suggest that malepsychologists do exhibit an androgynous gender role inboth professional and personal realms. A great deal ofthe prior literature indicates that androgynoustherapists have more adaptive communication skills and arebetter at assessing and treating their clients. Thisresult is therefore advantageous to therapeuticoutcomes.     

Use of carbon monoxide breath validation in assessing exposure to cigarette smoke in a worksite population

Assessed the usefulness of carbon monoxide (CO) breath validation of self-reported smoking status in a large worksite population (N = 4,647). CO assessment was performed as part of a baseline survey procedure. CO levels differed substantially in relation to self-reported smoking status and amount smoked. Correcting for ambient exposure (estimated by mean CO levels among never smokers) produced more satisfactory results than uncorrected CO levels. Striking company differences were observed in mean CO exposures among self-reported never smokers. An unexpected finding was that 17.1% of current smokers reported smoking less than daily. Although the CO measure was excellent in detecting moderate and heavy smokers, it was inadequate in detecting occasional and light smokers. If detection of occasional or lighter smoking is critical to the purposes of the study, the more expensive (but more accurate) cotinine measure is preferred.     

Analysis of memory codes and cumulative rehearsal in observational learning

The present study examined the influence of memory codes varying in meaningfulness and retrievability and cumulative rehearsal on retention of observationally learned responses over increasing temporal intervals. Symbolic codes combining meaningfulness with retrievability produced superior memory performances, but responses were poorly retained in symbolic representations containing only one of these properties. Individual response analysis further confirmed that the more meaningful the codes incorporating retrieval guides the better are modeled responses learned and retained. Cumulative rehearsal had differential effects on memory performances depending upon the serial input position of the responses and the form into which the modeled behavior was encoded. Code rehearsals facilitated retention of early and intermediate responses which were repeated more than later ones, but this was true mainly for codes vulnerable to loss. The overall findings provide further corroborative evidence that memory performances are governed more by information coding than by associative strengthening processes.
