Positive and negative affect produce opposing task-irrelevant stimulus preexposure effects

In three experiments, groups were exposed to either positive or negative affect video clips, after which they were presented with a series of task-irrelevant stimuli. In the subsequent test task, subjects were required to learn an association between the previously irrelevant stimulus and a consequence, and between a new stimulus and a consequence. Induced positive affect produced a latent inhibition effect (poorer evidence of learning with the previously irrelevant stimulus than with the novel stimulus). In opposition to this, induced negative affect resulted in better evidence of learning with a previously irrelevant stimulus than with a novel stimulus. In general, the opposing effects also were present in participants scoring high on self-report questionnaires of depression (Experiments 2 and 3). These unique findings were predicted and accounted for on the basis of two principles: (a) positive affect broadens the attentional field and negative affect contracts it; and (b) task-irrelevant stimuli are processed in two successive stages, the first encodes stimulus properties, and the second encodes stimulus relationships. The opposing influences of negative and positive mood on the processing of irrelevant stimuli have implications for the role of emotion in general theories of cognition, and possibly for resolving some of the inconsistent findings in research with schizophrenia patients.     

Mother's attachment representations of their premature infant at 6 and 18 months after birth

The effects of premature birth on attachment have generally been examined from the infant's perspective. There is a lack of data concerning parental attachment representations toward a premature child. Because of the psychological stress engendered in parents confronted with a premature birth, we hypothesized that their attachment representations would be altered during the first months after the hospital discharge. Fifty families with a premature infant (25–33 gestation weeks) and a control group of 30 families with a full‐term infant participated to the study. Perinatal risks were evaluated during hospitalization. To assess mothers' representations of their infant, the Working Model of the Child Interview (WMCI, Zeanah & Benoit, 1995 & Benoit, Zeanah, Parker, Nicholson, & Coolbear, 1997) were administered when their children were 6 and 18 months old. The severity of the perinatal risks was found to have an impact on the mothers' attachment representations. At six months, only 20% of the mothers of a prematurely born infant (30% at 18 months) had secure attachment representations, vs. 53% for the control group (57% at 18 months). Furthermore, mothers of low‐risk premature infants more often had disengaged representations, whereas distorted representations were more frequent in the high‐risk group of premature children. These findings suggest that the parental response to a premature birth is linked to the severity of postnatal risks. The fact that secure attachment representations are affected in mothers of low‐risk infants just as much as they are in mothers of high‐risk infants points to the need to conduct further studies aimed at evaluating whether preventive intervention for both low‐risk and high‐risk premature will be helpful.     

The experience of tedium in three generations of professional women

Tedium, defined as the experience of emotional, physical, and mental exhaustion, was studied in three generations of professional women, who were questioned extensively about their lifestyles, life stresses, and life attitudes. Results indicated that in spite of the differences in life features and pressures among the three groups, the similarities in their experiences, attitudes, and overall life satisfaction are rather impressive. The differences among the generations tended to cluster around the more stressful environment of college for the young preprofessional women, who experienced most tedium and were most overextended and conflicted, and around the more traditional attitudes toward women and women's issues expressed by the older postprofessional generation, who also had the least tedium. The midcareer professional women were characterized by more positive life attitudes, more satisfaction from their work, and by liberal feministic attitudes toward working women's issues. Three focal variables were hypothesized and documented to be important tedium correlates for all professional women. Of the three, role conflict rather than number of roles was found to be a positive tedium correlate. Sense of control and especially having social support systems emerged as significant negative tedium correlates.An earlier version of this article was presented as a paper at the Annual Convention of the American Psychological Association, San Francisco, August 26–30, 1977.

Antecedents, correlates, and consequences of sexual jealousy

The paper presents a social-psychological approach to the empirical study of sexual jealousy, after surveying the philosophical, sociological, anthropological, psychoanalytic, and nonscientific literature on the subject. The social-psychological approach focuses on the environmental and situational factors that cause people to act in a jealous manner. One hundred and three men and women varying in age, length of relationship, and relationship style responded to a specially designed sexual jealousy inventory. Results indicated that jealousy is a negative physiological, emotional, and mental state, experienced at least at some point of their lives by all the subjects in the study. Numerous antecedents, correlates, and consequences of jealousy were investigated and discussed. Fifty-four percent of the subjects described themselves as “a jealous person” even when they had good situational reasons to feel less secure in the relationship and to experience jealousy, and even though this dispositional self-attribution has negative consequences for coping.     

Sex and Gender As Raw Political Material: Local Women Negotiate Globalization

In Mexico and around the world women face globalization processes and changing economies that they have little power to refuse. Yet, like other groups on the margins, women confront globalization and make local uses of it. Sex and gender are deeply implicated in globalization and are the raw political material in struggles for and against parity for women.In this introduction to the special volume of Sex Roles on Maya women's negotiating globalization, I discuss local ways that women draw on sex and gender to encounter economic transformations, to expand parity in the public and the domestic spheres,and to create a we solidarity across class and ethnic differences.     

Biology Precedes, Culture Transcends: An Evolutionist's View of Human Nature

I will, first, outline what we currently know about the last 4 million years of human evolutionary history, from bipedal but small-brained Australopithecus to modern Homo sapiens, our species, through the prolific toolmaker Homo habilis and the continent wanderer Homo erectus. I shall then identify anatomical traits that distinguish us from other animals and point out our two kinds of heredity, the biological and the cultural.
Biological inheritance is based on the transmission of genetic information, in humans very much the same as in other sexually reproducing organisms. But cultural inheritance is distinctively human, based on transmission of information by a teaching and learning process that is in principle independent of biological parentage. Cultural inheritance makes possible the cumulative transmission of experience from generation to generation. Cultural heredity is a swifter and more effective (because it can be designed) mode of adaptation to the environment than the biological mode. The advent of cultural heredity ushered in cultural evolution, which transcends biological evolution.
I will, finally, explore ethical behavior as a model case of a distinctive human trait, and seek to ascertain the causal connections between human ethics and human biology. My conclusions are that (1) moral reasoning—that is, the proclivity to make ethical judgments by evaluating actions as either good or evil—is rooted in our biological nature; it is a necessary outcome of our exalted intelligence, but (2) the moral codes that guide our decisions as to which actions are good and which ones are evil are products of culture, including social and religious traditions. This second conclusion contradicts those evolutionists and sociobiologists who claim that the morally good is simply that which is promoted by the process of biological evolution.     

Increase in arab women's perceived power in the second half of life

An increase in perceived power in midlife was demonstrated among 60 middle-class Arab women in Israel. 20 of the women were young (age 20–40) 20 were middle aged (45–55) and 20 were older (60–80). Perceived power was studied using card 4 of the Thematic Apperception Test (TAT). The TAT stories were rated on three dimensions of perceived power: security, inner strength, and interpersonal influence. Results indicate that the young Arab women ranked lowest in security and inner strength. There was a bigger difference between the young women and the two other groups than between the middle-aged and older women. In addition, all three groups, while describing men as having more interpersonal power and security, still described women as having more inner strength.The authors wish to thank Latifa Manzur and Anat Zohar-Aizen, students at Tel-Aviv University, for their help in the data collection.
