Inhibition of the LH Surge by Restraint Stress in Cyclic Rats: Studies on the Role of GABAA and GABAB Receptors

There is evidence that stress can alter the activity in the brain of gamma-aminobutyricacid (GABA), a neurotransmitter that has been implicated in the regulation of LH secretion. In the present study the role of GABA in the restraint stress-induced inhibition of the LH surge was investigated in the intact cyclic rat. Intracerebroventricular (icv) administration of the GABAA receptor agonist muscimol (0.1, 0.5 or 1 μg) 5 min before the presumed onset of the pro-oestrous LH surge (at 0900 h) caused a dose dependent suppression of the surge. A single dose of the GABAB receptor agonist baclofen (1 μg; icv) injected at 0855 h postponed the onset of the LH surge, and repeated injections at 0855 and 1130 h suppressed the surge. These data indicate that GABA-ergic activity in the brain can inhibit the LH surge in the cyclic rat via GABAA and GABAB receptors. Pro-oestrous rats were subjected to 5 hrs of restraint starting at 0855 h. Pretreatment with the GABAA receptor antagonist bicuculine (1 μg; icv) at 0840, 0940 and 1040 h or pretreatment with the GABAB receptor antagonist phaclofen (10 μg; icv) at 0840 h were ineffective in preventing the restraint-induced inhibition of the LH surge. The results suggest that GABAA and GABAB receptors are not involved in the inhibitory effect of restraint stress on the LH surge.     

Intimacy,communication, and aggressive behaviors: Variations by phases of romantic relationship development

This study examined how phases of romantic relationship development (honeymoon, defining, and established) were related to positive and negative relationship qualities. Participants (N = 136) completed self‐report measures. Results found significant differences between phases of romantic relationship development for all three positive relationship qualities, but each had a unique pattern of variation: (a) levels of intimacy had a linear increase across phases, (b) constructive communication strategies were higher in the established phase as compared with the earlier phases, and (c) negotiation was higher in both the defining and established phases as compared to the honeymoon phase. Results for negative relationships qualities found an inverted U‐shaped pattern for both destructive communication strategies and psychological aggression.     

Features of Families with Major Affective Disorders

This article reports the authors' observations on 22 families in which a young adult member has been diagnosed as manic-depressive, and on 11 families in which a member has been diagnosed as suffering from major schizoaffective disorder. All families could be described as extremely rigid and bound-up systems. Many of them were characterized by a "restrictive parental complementarity" and reciprocal delegation, and they shared certain cognitive features and assumptions. "Manic-depressive" families showed similarities as well as differences when compared with families in which there were schizophrenic and serious psychosomatic disorders.     

Professional Politics and the Concepts of Family Therapy, Family Consultation, and Systems Consultation

At a time when an increasing number of professionals are calling themselves "family therapists," many teachers and theorists in this field are troubled that the term "family therapy" no longer adequately characterizes the concepts or activities of the field. Recently, clinical, political, and economic circumstances have emerged that suggest the need for alternatives to the role of "family therapist." By adding the roles of family consultant and systems consultant, we can open up new options for ourselves and our clients. During initial contacts with families, agencies, and other professionals, we can heighten our therapeutic potential by proceeding with consultative stocktaking, not starting with therapy. Family consultation also can assist in redirecting therapy when a new problem or an impasse develops, in focusing on competency rather than on pathology, and in engaging constructively with families that have a physically or mentally ill member.     

Empirical support for the gender‐as‐culture hypothesis.

This investigation provided a test of the gender‐as‐culture, or ‘two cultures’, hypothesis proposed by Maltz and Borker (1982) to explain male/female differences in language use. Analysis of previous empirical investigations located 16 language features that had consistently been shown to indicate communicator gender and these were tested within the framework of the four dimensions of intercultural style proposed by Gudykunst and Ting‐Toomey (1998): direct versus indirect, succinct versus elaborate, personal versus contextual and instrumental versus affective. Study 1 provided preliminary evidence supporting the hypothesized language‐feature‐by‐dimension relationships (e.g., male directives were rated more direct and female uncertainty verbs more indirect). In Study 2, respondents rated multiple exemplars of the 16 language features, as well as 16 contrasting foil sentences, on all four dimensions, finding that nearly all of the variables fell on the hypothesized intercultural dimensions. In Study 3, respondents rated four sets of naturally occurring target sentences and matching foil sentences, representing all language variables, on their appropriate intercultural dimensions in order to establish dimensional polarity. Results across the three studies supported the hypothesized language feature‐by‐stylistic dimension relationship for 15 of the 16 variables: The 6 male language features were rated as more direct, succinct, personal, and instrumental, whereas 9 of the 10 female features were perceived as more indirect, elaborate, and affective. The findings demonstrate that gender preferences for language use function in ways that are consistent with stylistic preferences that distinguish national cultures.     

Anticipatory Processing and Post‐Event Processing in Social Anxiety Disorder: An Update on the Literature

Two repetitive thinking processes that have been proposed in prominent maintenance models of social anxiety disorder (SAD) are anticipatory processing and post‐event processing. Research into these two processes has steadily increased over the last 20 years. This review highlights the main lines of existing research on anticipatory processing and post‐event processing, including studies on the nature of these processes, their association with social anxiety, the predictors, and consequences of these processes, as well as how these processes respond to treatments for SAD. The review also highlights some of the conceptual and methodological issues that have prevented the literature on anticipatory processing and post‐event processing from being more integrated and focused. Finally, the review draws together some new directions in terms of theory and research to further advance the field.
