Cigarette smoking and oral contraceptive use influence women's lipid, lipoprotein, and cardiovascular responses during stress

Investigated the effects of behavioral stress and smoking cigarettes on the lipid, lipoprotein, neuroendocrine, and cardiovascular responses of female smokers who either used or did not use oral contraceptives (OC). Thirty-five healthy female smokers (20 of whom used OC) relaxed, smoked, or sham smoked and then prepared, delivered, and reviewed a speech presented in front of a video camera. Results show that behavioral stress increased total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol, triglyceride, and free fatty acid levels, with significant increases in cholesterol, LDL-C, and free fatty acids apparent only among women who smoked during the session. In addition, OC users exhibited larger increases in triglyceride and blood pressure responses during stress than did nonusers whether or not they smoked during the protocol. Possible physiological mechanisms for each of the effects, as well as implications of the findings for understanding epidemiological associations among OC use, smoking, and coronary heart disease in women are discussed.     

‘Why should we talk to you? You'll only tell the Court!’ On being an informer and a family therapist

The family therapy literature recognizes the constraints imposed on a therapist's freedom and impartiality in a statutory agency. This paper shows that clinical settings that are apparently independent are not free of such constraints. The wider professional welfare system has confused expectations of a clinical agency that it should provide simultaneously both therapy and a measure of social control. An account is given of one hospital-based family therapy team's struggles to find manoeuvrability in child-focused statutory cases, so as to be helpful both to families and referrers. One method of working is illustrated with a case example.

Current and vestigial effects of overweight among women: Fear of fat,attitudinal body image,and eating behaviors

College females completed multiple, standardized measures of their fear of fat, attitudinal body image, and binge eating and dieting. Situational weigh-in measures were taken, including latency to get on the scale and anxiety while being weighed. Based on current weight and a structured weight history questionnaire, three groups were constructed: normal-weight subjects without an overweight history (NW; n=24), normal-weight subjects who were formerly overweight (FOW; n=16), and those currently overweight (OW; n=24). Group comparisons revealed, as expected, that OW females, relative to their NW peers, had more weight-related anxieties, more negative body experiences, and more frequent past-year dieting. Consistent with Stunkard's original proposition, the FOW group regarded their bodies as fatter and less affectively satisfying and expressed more weigh-in anxiety than NW participants. Currently normal-weight FOW subjects seldom differed from the currently OW individuals. Clinical and research implications are considered, particularly with regard to the psychological sequelae of weight loss.     

Sex-differentiated behaviors in nonsexist picture books

Charges of behavioral and sex-role stereotyping in preschool picture books have led to the publication of books that purportedly avoid or challenge traditional sex stereotypes (i.e., positive image or nonsexist picture books). This study sought to identify behaviors (as distinguished from sex-typed activities or social roles) exhibited by female and male characters in nonsexist books, and to compare these portrayals with those presented in more conventional picture books (Caldecott award-winners and contemporary best-sellers). A reliable coding system (interrater reliability exceeding 90%), permitting the identification of 15 target behaviors in the text and illustrations of picture books was developed and employed in the content analysis of 50 nonsexist and 46 conventional picture books. Stepwise discriminant function and chi-square analyses revealed highly independent females and nurturant and nonaggressive males in nonsexist books—portrayals that represent a clear departure from traditional sex stereotypes in this society. On the other hand, females in nonsexist books were more nurturant, emotional, and less physically active than males in either nonsexist or conventional books. Finally, with the single exception of aggressive behavior (males exceeding females), there was no indication of behavioral sex-typing in the conventional books. Implications are discussed.The author wishes to express his deep appreciation to Carol Quarton for her invaluable assistance in the development of the coding system used in this study. The author also wishes to think Mary Neal and Leslie Schindler for their careful and discriminating content analyses of the books, and Drs. George Milliken and Frank Saal for their statistical consultation. Finally, special thanks to Lorraine Nesmith, the former Children's Librarian at the Manhattan Public Library, Manhattan, Kansas, for her generous support and counsel throughout this project.     

On the ability to inhibit simple and choice reaction time responses: a model and a method

This article reports four experiments on the ability to inhibit responses in simple and choice reaction time (RT) tasks. Subjects responding to visually presented letters were occasionally presented with a stop signal (a tone) that told them not to respond on that trial. The major dependent variables were (a) the probability of inhibiting a response when the signal occurred, (b) mean and standard deviation (SD) of RT on no-signal trials, (c) mean RT on trials on which the signal occurred but subjects failed to inhibit, and (d) estimated RT to the stop signal. A model was proposed to estimated RT to the stop signal and to account for the relations among the variables. Its main assumption is that the RT process and the stopping process race, and response inhibition depends on which process finishes first. The model allows us to account for differences in response inhibition between tasks in terms of transformations of stop-signal delay that represent the relative finishing times of the RT process and the stopping process. The transformations specified by the model were successful in group data and in data from individual subjects, regardless of how delays were selected. The experiments also compared different methods of selecting stop-signal delays to equate the probability of inhibition in the two tasks.     

The effect of context during word perception in schizophrenic patients

Hospitalized chronic and acute schizophrenics were compared with age- and social-status-matched controls on word perception tests to measure the effect of context on recognition thresholds. In Experiment 1 the method of J. Morton (1964, British Journal of Psychology, 55, 165-180) was adopted to see how related and unrelated contexts influenced word recognition thresholds when both context and stimulus word were presented visually. Experiment 2 was an auditory analog of Experiment 1 and in addition the chronic schizophrenics were selected on the basis of a presence or absence of auditory hallucinations. The influence of context on perceptual thresholds was quite normal in all schizophrenics. However, analysis of the incorrect responses elicited showed that some schizophrenic subjects do produce bizarre or irrelevant responses or perseveration to a greater extent than their controls. These results are explained in terms of automatic and strategic modes of information processing. The automatic processes responsible for the adjustment of perceptual thresholds operate normally in schizophrenics but response production which demands strategic selection and editing of responses is prone to malfunction which results in the observed deviations in the normal use of language.
