Social Motives,Emotional Feelings,and Smiling

Previous research has established that the facial displays of those who listen to stories are influenced by the social context in which this happens. H owever, experienced affect was not measured in these studies, and the story stimuli were not systematically manipulated. We report a study in which participants listened to stories that varied in rated funniness, and that were told by either a friend or a stranger via one of the following channels: Tape recorder, telephone, or face-to-face. D ependent measures included facial activity, subjective feelings, and social motives. We anticipated that facial displays would be influenced by story type and by social context, and that the former effects would be mediated by experienced affect, whereas the latter effects would be mediated by social motives. The funnier story elicited more smiling, but this was not mediated by experienced affect. Social context also influenced smiling, and this effect appeared to be mediated by social motives.     

TRANSFORMING LESBIAN SEXUALITY

Women are objectified and sexualized by the media and the economy, so that they live in a culture of sex. Lesbians are excluded from the mainstream sexual and appearance norms for women, yet are affected by these norms, including the association of sex and violence against women. The word sexuality has been used to connote both sexual orientation and sexual activity, and it is argued that this dual meaning illustrates the dominance of patriarchal definitions of women's sexuality. This article discusses methodologic issues in understanding who is a lesbian and presents various models or dimensions for understanding who is included in research about lesbians. It asks the question "What is sex?" and reviews the implications of this question for lesbian sexual activity. This question has implications for a collorary question: "What is a lesbian relationship?", and the article discusses the implications of this question on various forms of sexual and nonsexual relationships among lesbians.     

Apes' and children's understanding of cooperative and competitive motives in a communicative situation

Chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) (Study 1) and 18- and 24-month-old human children (Study 2) participated in a novel communicative task. A human experimenter (E) hid food or a toy in one of two opaque containers before gesturing towards the reward's location in one of two ways. In the Informing condition, she attempted to help the subject find the hidden object by simply pointing to the correct container. In the Prohibiting condition, E held out her arm toward the correct container (palm out) and told the subject firmly 'Don't take this one.' As in previous studies, the apes were at chance in the Informing condition. However, they were above chance in the new Prohibiting condition. Human 18-month-olds showed this same pattern of results, whereas 24-month-olds showed the opposite pattern: they were better in the Informing condition than in the Prohibiting condition. In our interpretation, success in the Prohibiting condition requires subjects to understand E's goal toward them and their behavior, and then to make an inference (she would only prohibit if there were something good in there). Success in the Informing condition requires subjects to understand a cooperative communicative motive - which apparently apes and young infants find difficult.     

Effects of slow-release caffeine and a nap on driving simulator performance after partial sleep deprivation

A driving simulator was used to evaluate the effectiveness of a 30-min. nap and 300-mg slow-release caffeine as countermeasures to drivers' sleepiness induced by partial sleep deprivation. 12 participants were allowed 45 hr. time in bed at the laboratory. Driving performance then was measured twice--at 9 a.m. and at 1 p.m.--by a 45-min. driving task on a simulator. Subjective sleepiness/alertness and mood were assessed four times on the Stanford Sleepiness Scale and the Profile of Mood States. Driving performance was assessed as Lane Drifting, Speed Deviation, and Accident Liability. A 30-min. nap opportunity and 300 mg of slow-release caffeine both were successful in counteracting drivers' sleepiness. The remedial effect of slow-release caffeine lasted longer than that of the nap, that is, it was also effective in the afternoon session. This suggests that slow-release caffeine represents a valuable countermeasure that, in the case of partial sleep deprivation, is preferred to a nap when sleepiness has to be counteracted for a longer time.     

Adrenocortical reactivity and social competence in seven year-olds

We examined temporal changes in salivary cortisol in response to a peer self-presentation task in a group of seven year-olds, some of whom scored high, average, and low on the Harter, 1983 Perceived Social Competence Scale. Salivary cortisol was measured pre-task, and 20 and 35 min post-task. We found a significant relation between individual differences in perceived social competence and salivary cortisol reactivity in response to the task. Children who perceived themselves as socially competent exhibited a significantly greater decrease in salivary cortisol from 20 to 35 min following the task compared with children who self-reported a relatively lower degree of social competence. We speculate on the meaning of salivary cortisol changes in childrens socio-emotional development.     

A computer-graphic technique for the study of body size perception and body types

We present a novel approach for measuring body size estimation in normal and eating-disordered women and men. Clinical categories of body types were used as prototypes. By comparing the subjective appearance of a person’s body with prototypes, we can understand how different attributes of his or her body shape contribute to perception of body size. After lifelike random distortions have been applied to parts of their body image, individuals adjust their body shapes until they converge on their perceived veridical appearance. Exaggeration and minimization of particular body areas measured with respect to their true shape and with different prototypes can be expressed as numerical deviations. In this way, perceived body size and body attractiveness can be appraised during the course of diagnosis and treatment of eating disorders.     

Otto Rank's Conception of the Will

Rank is the only psychoanalyst to introduce the concept of will as central to an understanding of human psychology. The function of willing and the clear uniqueness of each individual challenge the causal, deterministic thinking of Freudian psychoanalysis and thereby the predictability of behavior. Thus, for the individual will means choice, and therefore moral responsibility for one's own acts. It also means the opportunity to create the new. The very formation of the individual self as it separates and differentiates itself from the maternal matrix is a creative act—one which inevitably precipitates a certain, but normally manageable, amount of guilt because of empathic feelings for the one who has been left—originally the mother. Beyond the creation of self, the will, through its creative role, helps to allay the inevitable human fear of the final separation, namely death by producing those manifestations of civilization—art, literature, music, and science—which in their generative capacity insure immortality.     

Correlates of Satisfaction with a Peer Evaluation System: Investigation of Performance Levels and Individual Differences

The present research examined the effects of performance level and individual differences on participants' satisfaction with a peer evaluation system. One hundred and fifty-three individuals working in groups completed a questionnaire assessing self-monitoring, self-esteem, and individualism. A peer evaluation system was used at the end of the project. Subjects indicated their satisfaction with and reaction to the peer evaluation system. The findings demonstrated that performance level, individualism, self-esteem, and self-monitoring helped to understand and to predict group members' reactions to the peer evaluation system. Implications for future research and implementation of peer rating systems are discussed.     

THREE-MONTH-OLD INFANTS CAN LEARN TASK-SPECIFIC PATTERNS OF INTERLIMB COORDINATION

Three-month-old infants cannot yet coordinate and control their limbs for functional tasks like reaching or locomoting This study demonstrates that given an appropriate, novel task, infants can transform their seemingly spontaneous kicking movements into new and efficient patterns of interlimb coordination even at this early age Three-month-old infants were allowed to control the movement of an overhead mobile by means of a string attached to their left ankles In addition, some groups had their two legs yoked together at the ankle with a soft elastic The elastic permitted kicks to be coordinated in any pattern—alternating, single, or simultaneous—but simultaneous kicks provided the most vigorous activation of the mobile All infants kicked more and faster when their kicks were reinforced by mobile movement than when their kicks did not activate the mobile However, only the yoked infants increasingly moved their legs in a simultaneous, or in-phase, pattern The study suggests that learning processes are in place at 3 months for infants to discover a match between their interlimb coordination patterns and a specific task, and that these learning processes, rather than autonomous brain "maturation," may underlie the acquisition of motor skills
