Homosexual and heterosexual sex-role orientation on six sex-role scales

A comparison was made of the sex roles of homosexual and heterosexual men and women on the Bem Sex Role Inventory, Personality Attributes Questionnaire, Personality Research Form Androgyny Scale, Adjective Checklist Masculinity and Femininity Scales, Extended Personality Attributes Questionnaire and Undesirable Characteristics Scale. The results indicated that homosexuals and heterosexuals differ in their response to different aspects of sex roles. The most consistent difference was the greater femininity of male homosexuals in respect to male heterosexuals. Other differences were scale-specific and the low interscale comparability indicated such scales should not be used interchangeably. Differences between results of studies comparing sex roles of the homosexuals and heterosexuals appear attributable to sample heterogeneity and distinctions between sex-role scales.     

Behaviorism: Are reports of its death exaggerated?

Despite reports that behaviorism is dead or dying, examination of the data indicates otherwise. The opinions of psychology historians, the number of professional associations devoted to behaviorism, and the increasing number of behavioral publications all support the conclusion that behaviorism is vital and growing.     

A developmental exploration of the fear of success phenomenon as cultural stereotype

Given prior research suggesting that fear of success may be a function of cultural expectations rather than an intrapsychic motive held by women, this cultural phenomenon was placed in juxtaposition with reactions to women and men failing. It was expected that women would not be rated negatively for failure. It was also expected that in a sample of third, sixth, ninth, and twelfth graders, younger children would be more dogmatic than older children in applying cultural stereotypes to these situations. The children responded on semantic differential scales to the cue of Anne (John) succeeding (failing) in medical school. The children rated a successful person much happier than one who failed, and the sex of the person succeeding or failing was entirely irrelevant. However, the results were as predicted for niceness: A woman was somewhat less nice than a man when they both succeeded, but a man was much less nice when they both failed. In addition, there were no interactions with the age or sex of the respondents. Thus, sex-role expectations are relevant to some attributes of individuals but not others, and these expectations are well established and easily applied as early as third grade.The authors gratefully acknowledge the assistance of the students, staff, and parents of the DeForest, Wisconsin, school district.

The effects of metabolic stress and vagotomy on emotional learning in an animal model of anxiety

The aim of the present study is to evaluate the role of the blood glucose (BG) level in emotional learning in the elevated plus maze (EPM), an animal model of anxiety. In Experiment 1, male Wistar rats were submitted to different EPM trial lengths (1- or 5-min). Blood samples were withdrawn before and after the maze exploration, through a polyethylene cannula chronically implanted into the jugular vein. In Experiment 2, the animals received either saline or 2-deoxy-D-glucose, a glucoprivic drug (2-DG, 250 or 500 mg kg(-1)) by i.p. route, 30 min before a 5-min EPM exposure and were retested in the maze (Trial1/Trial2 EPM procedure) 24 h later. In an independent group of rats, blood samples were withdrawn 0, 5, 15, and 30 min after 2-DG administration, through the jugular vein, to determine BG. In Experiment 3, the animals underwent a vagotomy and were tested in a Trial1/Trial2 EPM procedure four weeks later. The results showed that rats exploring the EPM for 5 min displayed increased fear and higher hyperglycemia than those exploring the EPM for 1 min. In addition, rats submitted to 5-min EPM Trial1 length displayed higher level of fear on Trial2, as well as higher percentage of shortening of the %Open arm entries and %Open arm time from Trial1 to Trial2, which characterizes the occurrence of emotional learning. In contrast, rats previously vagotomized or treated with 2-DG (500 mg kg(-1)) showed the same level of fear on both EPM trials and a low percentage of shortening, from Trial1 to Trial2, of the %Open arm entries and %Open arm time, indicating poor emotional learning. The data is discussed regarding the role of glycaemia in emotional learning in the EPM.     

Linking Substance Use and Problem Behavior Across Three Generations

This study examined patterns of between-generation continuity in substance use from generation 1 (G1) parents to generation 2 (G2) adolescents and from G2 adult substance use and G1 substance use to generation 3 (G3) problem behavior in childhood. Structural equation modeling of prospective, longitudinal data from 808 participants, their parents, and their children showed low levels of G1 to G2 cross-generational continuity in the general tendency to use drugs. This effect was fully mediated by G2 early adolescent behavior problems. Drug-specific residual effects were observed across generations for cigarette smoking. Once established in adolescence, substance use in G2 showed stability over time. G2 substance use at age 27 significantly predicted G3 problem behavior. G1 substance use also was related to G3 problem behavior indirectly. These findings highlight the importance of interrupting intergenerational cycles of substance use and problem behavior.     

Self-monitoring and close relationships

Three types of close relationships have received attention from theorists and researchers interested in self-monitoring: friendships, romantic relationships, and marriage. Our review of this literature was organized around three phases of relationships: initiation, maintenance, and dissolution. Across the three types of relationships, consistent differences between high self-monitors and low self-monitors emerged concerning the structure of their social relationships (segmented vs. integrated), the basis for choosing friends and romantic partners (activity-based vs. person-based), and the orientation taken to romantic and marital partners (uncommitted vs. committed). Across all three types of relationships, however, little is known about the processes and consequences involved in the dissolution of close relationships for high self-monitors and low self-monitors. Relatively little is also known about the processes used by high self-monitors and low self-monitors to maintain their friendships and marriages. In addition to addressing these deficiencies in the literature, theorists and researchers interested in self-monitoring and close relationships need to develop sophisticated, causal models that can account for (a) interaction exchanges in the relationships, (b) dyadic as well as individual levels of analysis, and (c) temporal and situational changes in the course of close relationships.     

Genetic associations of alcohol dehydrogenase with alcohol use disorders and endophenotypes in white college students

Associations of alcohol dehydrogenase (ADH) gene polymorphisms (ADH1B*2 and ADH1C*1) with a lifetime alcohol use disorder (AUD) were examined in White college students. Alcohol-related endophenotypes likely to be influenced by elevations in acetaldehyde were also assessed. Individuals with an ADH1B*2 allele had lower rates of AUDs, consumed a lower maximum number of drinks in a 24-hr period, reported a greater level of response to alcohol, were more likely to have experienced alcohol-induced headaches following 1 or 2 drinks, and reported more severe hangovers than those lacking this allele. These findings are consistent with the hypothesis that enhanced sensitivity to alcohol and lower levels of alcohol use reflect the mechanism by which ADH1B*2 protects against developing an AUD.     

Parallel processing in complex visual discrimination

In a “same-different” reaction time (RT) task pairs of stimuli varying along one or more dimensions are presented and S is required to indicate, as rapidly as possible, whether the stimuli are physically identical or different. This task was employed in three experiments investigating the processes by which multidimensional stimuli are discriminated. The results indicated that stimulus dimensions are compared in parallel; that the time required to interrogate a dimension varies randomly across trials and is dependent upon the time required to interrogate other dimensions present in test stimuli, and that comparisons terminate upon the detection of information sufficient for a correct response.
