Extramarital sex: An examination of the literature

Extramarital sex in the marital system often provides difficult dilemmas for marital therapists in regard to treatment approaches. The authors examine various motivational and perceptual aspects among spouses for engaging in sexual activity outside the marriage. Implications for both research and treatment are discussed.     

Philosophy and the morality of abortion

ABSTRACT Abortion is a philosophically interesting issue because both sides seem so certain of their conclusions, yet the issue is at the same time clearly a derivative one. It is also highly political, and needs to be seen within the context of the growth of the women's movement. A philosophical overview of the issue in section 1 construes the central claims of the pro-choice and anti-abortion positions as moral and conceptual constructions, which extend everyday moral thinking into the area of abortion. It notes the interesting relation between such constructions and other arguments about abortion, and how this is responsible for their social and historical specificity. Section 2 defends the pro-choice position as a victory of moral sensitivity over linguistic guile. Section 3 situates the argument within the politics of feminism, and recognises the limited contribution which philosophy is able to make.     

Parents' behavioral norms as predictors of adolescent sexual activity and contraceptive use

The influence of parental factors on adolescent sexual behavior and contraceptive use has been examined previously, and findings have been contradictory. Previous studies, which found little relationship between parental norms and adolescent sexual activity, have been limited by their failure to recognize developmental differences in the relative weight of parent and peer influences between younger and older teens and by use of selected samples, resulting in a restriction of range. The current study differs in that it utilizes a clustered sample household survey of 329 males and females, aged 14 to 17, and 470 of their parents. Using multiple regression analysis, it was found that parents' reported behavioral norms account for 5% of the variance in whether adolescents have had intercourse, and for 33% of the variance in use of contraception at last intercourse. The study suggests that while parents' normative beliefs have limited effect in the decision to become sexually active, they have considerable impact on later contraceptive use.     

Processing of visual syntax in a globally aphasic patient

A globally aphasic patient was trained on a computerized visual communication system. His ability to comprehend reversible locative prepositional phrases after training was studied and compared with the performance of Broca's aphasics on a similar task. This patient's ability to generalize symbols for actions was also investigated. The results demonstrate our patient's capacity to master a formal visual syntax in the absence of natural language and illustrate how this capacity may be used successfully in a visual communication system. A problem in generalizing symbols for actions is demonstrated, suggesting that certain heuristic and cueing capabilities in the approach may be helpful.     

Visual and phonological components of working memory in children

Previous studies have shown that young children's immediate memory for a short series of drawings of objects is mediated by a visual component of working memory, whereas older children rely chiefly upon a phonological component. Three experiments investigated the hypothesis that older children rely also, but to a lesser extent, on visual working memory. Experiment 1 confirmed previous evidence that 11-year-olds' memory is disrupted by phonemic similarity of object names, but is unaffected by visual similarity of the objects themselves. However, when articulatory suppression was used to prevent phonological coding, levels of recall were sensitive to visual rather than phonemic similarity. Experiment 2 compared the effects of interpolating an auditory-verbal or a visual postlist task on memory for drawings viewed either with or without suppression. The visual task had a clear disruptive effect only in the suppression condition, where it interfered selectively with recall of the most recent item. Experiment 3 compared the effects of interpolating an auditory-verbal or a mixed-modality (visual-auditory) postlist task when subjects were not required to suppress. There was greater interference from the mixed-modality task, and this effect was confined to the last item presented. These experiments are taken as confirming the presence of a small but reliable contribution from visual memory in 11-year-old children's recall. As in younger children, visual working memory in 11-year-olds is sensitive to visual similarity and is responsible for a final-item visual recency effect. The results also show that older children's use of visual working memory is usually masked by the more pervasive phonological component of recall. Some implications for the structure of working memory and its development are discussed.     

Rehearsal of faces and details in action events

The relationship between mental rehearsal and facial identification accuracy was explored in two experiments involving either a staged classroom event or a video scenario. The results suggest that when subjects rehearsed immediately following an event, compared to subjects in non-rehearsal conditions, identification accuracy was increased when the target face was unchanged in appearance but was reduced when the face was changed slightly in appearance from viewing to test. However, when rehearsal of the event was delayed 10 minutes, identification accuracy was improved even when the face had changed in appearance. Immediate rehearsal, in contrast, led to a reduction in identification performance. In short, in some circumstances the gains in specific memory brought about by mental rehearsal serve to reduce than improve identification accuracy. The relevance of these findings to memory theory and everyday eyewitness testimony is discussed.     

Relation between self-reported affect and drug urges and cravings in continuing and withdrawing smokers.

In 2 experiments we investigated the effects of withdrawal and stress on the affective correlates of urges to smoke. In both, habitual cigarette smokers were divided into continuing and withdrawing smoker groups. In the 1st study, 44 adults reported current mood, urge, and expectations over a 24-hr period. In the 2nd, a controlled laboratory study, urge, affect, and physiological data were obtained from continuing and withdrawing groups (N = 64) exposed to high- or low-stress conditions. Urges among withdrawing smokers were positively associated with negative affect and negatively associated with positive affect; continuing smokers reported urges that were directly associated with positive affect and unrelated to negative affect. Stress and withdrawal produced urge self-reports that were related to negative affect. Moreover, subjects who smoked after exposure to withdrawal and stress reported greater pleasure and arousal than did other subjects.
