Measurement and mismeasurement of mood: recurrent and emergent issues

The affective explosion in psychology has led to tremendous advances in mood measurement. Mood ratings reflect a hierarchical structure consisting of two broad dimensions-Positive Affect and Negative Affect-and multiple specific states. Brief scales have been developed that reliably assess Positive and Negative Affect across different populations and time frames, in both between- and within-subject data. We examine controversies related to (a) the content of these higher order scales and (b) the independence of Positive and Negative Affect. Regarding the latter, we show that Positive and Negative Affect scales remain largely independent across a wide range of conditions, even after controlling for random and systematic error. Finally, there remains little consensus regarding the lower order structure of affect. This lack of a compelling taxonomy has substantially slowed progress in assessing mood at the specific affect level.     

Process characteristics of worry and obsessive intrusive thoughts

One hundred and twenty-five university students were administered a battery of self-report measures to assess worry disposition and content, frequency of obsessive intrusive thoughts, and 10 conceptually derived appraisal dimensions of worry and obsessional intrusions. Process ratings indicated that the worrisome thoughts were considered more disturbing than the ego-dystonic intrusive thoughts. Worry was also distinguished by a focus on the possible consequences of negative events, whereas concern about the personal meaning of the thought was a unique process dimension for obsessive intrusive thoughts. Both content and process variables are important in differentiating worry and obsessive-like intrusive thoughts in a nonclinical population.     

The Unintended Negative Consequences of Sympathy for the Stigmatized1

Research on attitudes toward the stigmatized indicates that negative feelings and stereotypes toward the stigmatized are often mixed with positive feelings of sympathy and concern. Three studies investigate the hypothesis that positive outcomes for the stigmatized that are motivated by sympathy may have unintended negative consequences for self-esteem, affect, and motivation. Subjects were asked to imagine themselves in the position of a stigmatized person who received a job either because he or she was qualified, or out of sympathy for a stigmatizing condition. Results indicated that subjects reported lower state self-esteem, more negative affect, and lowered work motivation when the job was offered out of sympathy rather than on the basis of qualifications. Study 2 showed that the negative effects of sympathy occur whether the basis for the sympathy is prejudice and discrimination or mobility problems faced by the stigmatized individual. The third experiment showed that sympathy has negative effects when the sympathy is based either on individual or group-based problems imposed by the stigmatizing condition. The findings are discussed in terms of the attributional ambiguity surrounding positive outcomes faced by the stigmatized and applied to the effects of affirmative-action programs.     

The generation effect and the modeling of associations in memory

The search of associative memory (SAM) model of Gillund and Shiffrin (1984) was applied to data of two experiments that examined the generation effect (Slamecka & Graf, 1978). Subjects studied a list of related word pairs, in which they either read both words in the pair or generated the righthand response term using the left-hand stimulus term plus the response word fragment as generation cues. Experiment 1 manipulated encoding condition within subjects and used an incidental learning procedure. Experiment 2 manipulated encoding condition between subjects and used an intentional learning procedure. Memory was tested with recognition, cued recall, and free recall. A higher order association model gave a better and more parsimonious fit to the results than did an item-level association model. The relationship between various versions of SAM and current accounts of the generation effect are discussed, particularly the two-factor theory of Hirshman and Bjork (1988).     

Sacrificing one to save many

Attempts to solve the Trolley Problem by means of a single principle have proved unpersuasive. Nor can the intuition about Transplant be adequately grounded in the hypothetical dissent of rational contractors. It is explained by the initial liability principle, that loss should lie where it falls unless there is sufficient reason to shift it. If we did not think we should accept misfortune in such cases and thought that minimising loss of life was sufficient reason to shift the loss we should not be according others the minimum respect and treatment we feel is their due. The intuition about Trolley is explained by the affinity of that case to the pure case where the choice is between saving many and saving fewer, where minimising misfortune is the only credible option. But these considerations are not yet enough to accommodate the cases that lie between the extremes of Trolley and Transplant. We can handle the intermediate cases by attempting to assimilate them to one or other paradigm and to one another with a sensitivity to morally relevant and irrelevant differences that seeks initially to be faithful to the values reflected by our moral intuitions. Those intuitive judgements are unlikely to survive such an examination wholly unmodified.     

The numbers game: Gender and attention to numerical information

Research suggests that males outperform females on standardized tests of math ability from early adolescence onward. Several explanations for this difference focus on the different experiences of females and males with numerical information. We reasoned that males have more experience with numerical information than females because typical male interests (e.g., sports) are more likely to involve numerical information than typical female interests (e.g., physical appearance). Thus, we predicted that males would attend more to numerical information than would females, at least when the information was presented in a male-related or gender-neutral context. Females were expected to attend more than males when the context was female-related. Results using White/Caucasian subjects provided some support for these predictions. Implications for future research on the relationship between the gender-linkage of math materials and gender differences in math performance are discussed.     

MATERNITY LEAVE AND WOMEN'S MENTAL HEALTH

The Wisconsin Maternity Leave and Health Study addresses an important policy issue, parental leave, by investigating the work status, maternity leave, and mental health of 570 women. In the longitudinal design, the women, all of whom were living with a husband or partner, were interviewed during the fifth month of pregnancy, 1 month postpartum, and 4 months postpartum. At 4 months postpartum, full-time workers, part-time workers, and homemakers did not differ in depression or anger, but full-time workers showed elevated anxiety compared with the other two groups. In multiple regression analyses, length of leave interacted significantly with marital concerns when predicting depression; women who took a short leave (6 weeks or less) and were high on marital concerns had the highest depression scores. Short maternity leave can be conceptualized as a risk factor that, when combined with other risk factors such as marital concerns, places women at greater risk for depression.
