Improving Predictive Accuracy with a Combination of Human Intuition and Mechanical Decision Aids

This study examines the intuitive combination of human judgment and mechanical prediction under varied information conditions. As expected, mechanical prediction outperformed human intuition when based on the same information, but a combined approach was best when judges had access to relevant information not captured by the model (information asymmetry). The model was useful for differentiating between the event outcomes (improved slope), while eliminating the bias caused by base-rate neglect. Human intuition was useful for incorporating relevant information outside the scope of the model, resulting in improved slope and reduced judgment scatter. The addition of irrelevant information was detrimental to judgment accuracy, causing an increase in bias and a reduction in slope. These results provide insight intohowandwhencombining mechanical prediction and human intuition is likely to result in improved accuracy.     

Gender Differences in Spatial Task Performance as a Function of Speed or Accuracy Orientation

Performance differences in spatial abilities as a function of gender may be modified by practice and relevant background experiences, as well as by directions given in laboratory situations. We examined whether a focus on speed or accuracy influenced performance in various spatial domains, using several different scoring techniques. Men and women from a small, predominantly White private college completed tasks of spatial perception, spatial visualization, and mental rotation under one of three conditions: speed-emphasis, accuracy-emphasis, or control. Participants also provided information concerning experiences pertinent to spatial ability. Results revealed relative parity between men and women on tasks of spatial visualization and spatial perception; speed/accuracy orientation did not alter these findings. Men outperformed women on mental rotation, but only when scored in a strict manner and when explicitly told to focus on accuracy, but not when directional emphasis was absent or geared toward speed. Self-reported background in math, sports, and the arts was unrelated to performance. The results are discussed in terms of women's efficacy beliefs about performing tasks explicitly designated as spatial in nature.     

Studies of instrumental behavior with sexual reinforcement in male rats (Rattus norvegicus): I. Control by brief visual stimuli paired with a receptive female

We describe a novel procedure for measuring instrumental sexual behavior in the male rat by using a second-order schedule of presentation of sexual reinforcement, an estrous female. Experimental assessment and validation of the paradigm have been achieved by examining (a) the importance of the conditioned stimulus in maintaining instrumental responding by measuring the effects of its omission during a test session, (b) the effects and motivational specificity on instrumental behavior of the postejaculatory refractory period (a period of sexual unarousability) and of satiety for food by measuring the impact of each manipulation on animals working for food and for a female, (c) the effects of replacing an estrous female with an anestrous one as the earned reward, and (d) the correlations between conditioned and unconditioned measures of sexual behavior. We conclude that the second-order paradigm provides a means of distinguishing between the effects of neuroendocrine manipulations on incentive motivational and performance variables underlying the expression of sexual behavior.     

Dominance: Another Facet of Type A1

Aggression, but not dominance, is typically used as a criterion for the assessment of Type A behavior. This study proposed and demonstrated that nonaggressive dominance, defined as interpersonal resistance or persistence in efforts to control a competitive situation, is associated with Type A behavior for both males and females. Forty males and 35 females typed with the Jenkins Activity Survey participated in a revised version of the classic Deutsch and Krauss (1960) competition paradigm. Both A males and females were more dominant than their respective Type B counterparts. Type A males were not different from Type A females in persistence, nor were Type B males different from Type B females. Female Type A's were more resistant to their competitor's efforts at controlling the situation than were their Type B counterparts. Male Type A's did not differ from their Type B counterparts in resistance. The implications of these results in further elucidating the mechanisms underlying the relationship between Type A and pathophysiologic health hazards are discussed.     

Work and Family Commitment and Decision-Making Status Among Emerging Adults

This study was designed to investigate work–family attitudes among emerging adults. Participants were 46 male and 49 female college juniors and seniors. Men and women had similar levels of work and family commitment. For women there was a negative correlation between work and family commitment. Exploratory analyses indicated different relationships between work decision-making status and commitment and family decision-making status and commitment. In addition, whereas men were more likely than women not yet to have thought about family roles, women were more likely than men to have decided about family roles. Implications of these findings for our understanding of the processes and meanings of emerging adult men's and women's decisions about entry into and commitment toward work and family roles are discussed. Although earlier literature employs the term “young adults” to refer to individuals in the emerging adult stage of development, for the sake of consistency we use the term “emerging adults” throughout this article.     

“I’m Not a Pimp,but I Play One on TV”: The Moral Career and Identity Negotiations of Third Parties in the Sex Industry

Goffman described the moral career of stigmatized persons as a process by which an individual acquires a stigmatized identity. His analysis, which assumes that individuals recognize and adopt the normative framing of their behavior, glosses over individual identity negotiations. Drawing on 50 interviews with sex industry third parties, this article examines stereotype consciousness—defined as the interactional processes that lead individuals to recognize that they have a discreditable identity. We explore how participants negotiate their identities in response to the social and legal constructions of pimps, procurers, and traffickers, and examine their resistance to the stigmatizing stereotypes that characterize their work.     

Relationship Contexts as Sources of Socialization: An Exploration of Intimate Partner Violence Experiences of Economically Disadvantaged African American Adolescents

Intimate partner violence (IPV) among African Americans is a serious public health concern. Research suggest that African Americans adolescents, particularly those from economically disadvantaged communities, are at heightened risk for experiencing and perpetrating dating violence compared to youth from other racial and ethnic groups. In the present study, we examined different relationship contexts that are sources of IPV socialization. Semi-structured interviews were conducted with 22 economically disadvantaged African American adolescents. Content analysis yielded five relationship contexts through which the participants witnessed, experienced, and perpetrated IPV: (a) adolescents’ own dating relationships (64%), (b) siblings and extended family members (e.g., cousins, aunts, uncles) (59%), (c) parent-partners (27%), (d) friends (23%), and (e) neighbors (18%). Adolescents also frequently described IPV in their own dating relationships and in parent-partner relationships as mutual. Moreover, they appeared to minimize the experience of IPV in their own relationships. Efforts to reduce rates of IPV among economically disadvantaged African American adolescents should consider these relational contexts through which adolescents are socialized with regards to IPV and adolescents’ beliefs about mutual violence in relationships. Results highlight the importance of culturally relevant prevention and intervention programs that consider these relationship contexts.     

The association of antidepressant and statin use with death and incident cardiovascular disease varies by depression severity

Depression has been reported to be associated with a greater risk of death and cardiovascular disease (CVD); however, the impact of antidepressants (ADM) on CVD risk remains controversial. Statin use is known to decrease CVD risk. Whether the use of these medications together affects CVD risk has not been studied. Patients (N = 26,828) completing the patient health questionnaire (PHQ-9), ≥40 years of age, without prior CVD, and no prior ADM use were studied. Depressive severity was categorized as none-mild (PHQ-9 score ≤14, n = 21,517) and moderate-severe (PHQ-9 score ≥15, n = 5311). Cox hazard regression was used to evaluate the association of no ADM/no statin use (n = 23,104 [86.1%]), ADM/no statin use (n = 877 [3.3%]), no ADM/statin use (n = 2627 [9.8%]), and ADM/statin use (n = 220 [.8%]) with major adverse cardiovascular events (MACE: death, CAD, stroke). Patients averaged 56 ± 12 years; 61% female. There were 1182 (4.4%) 3 year MACE events. The association of ADM and statin use with MACE varied by depressive symptom severity, with statin therapy associated with a decreased risk in the none-mild group (HR = .78, p = .007) and ADM in the moderate-high group (HR = 0.58, p = 0.02). Concomitant use of ADMs and statins did not appear to provide additive benefit.     

Helpful Only in the Abstract?

ABSTRACT— This study tested the hypothesis that empathizing with out-group members is beneficial outside of, but not within, intergroup-contact situations. We predicted that in the context of intergroup interaction, the potential for evaluation would lead individuals' perspective-taking efforts to take on an egocentric and counterproductive flavor. As predicted, when empathy was instantiated during an intergroup exchange, it failed to exert its usual positive effect on intergroup attitudes and led higher-prejudice individuals to derogate an out-group member who was an interaction partner; empathy also blocked the prejudice-reducing influence of intergroup contact. Mediation analyses indicated that activation of negative metastereotypes regarding the out-group's view of the in-group accounted for these effects. The findings, which demonstrate ironic effects of empathy in intergroup interaction, indicate that interventions based on studies of individuals' reactions to out-group members in the abstract might have dramatically different consequences when put into practice in real exchanges between members of different groups.
