The relationship between menopausal status, phase of menstrual cycle, and replacement estrogen on cognition in healthy women without dementia

The authors examined the effect of menopausal status on several aspects of cognition in 4 groups of women (young premenopausal women, middle-aged premenopausal women, naturally postmenopausal women not using hormone therapy, and postmenopausal women using hormone replacement therapy). Participants (N = 48) completed questionnaires designed to assess psychological and physical health. The authors administered a test battery consisting of 10 neuropsychological tests to assess cognitive functioning. Using multivariate analyses of covariance with age as the covariate, the authors found a significant main effect of menopausal status on attention and complex processing abilities. Postmenopausal women using hormone replacement therapy significantly outperformed postmenopausal women not using hormone therapy on the Trail Making Test, Part B of the Halstead-Reitan (R. M. Reitan, 1958). This effect was significant even when the authors controlled for the effects of age, vocabulary levels, and education. Results are consistent with previous findings and may provide further evidence for an ameliorative effect of estrogen replacement therapy on specific cognitive functions.     

Exemplary efforts in psychology to recruit and retain graduate students of color

Many psychology departments are striving for a greater representation of students of color within their graduate preparation programs with the aim of producing a more diverse pool of psychological service providers, scientists, and educators. To help improve the minority pipeline in psychology, the authors identify and describe recruitment and retention strategies used at 11 departments and programs considered to be making exemplary efforts to attract and retain minority students of color. The strategies most consistently used included engaging current minority faculty and students in recruitment activities, offering attractive financial aid packages, having faculty members make personal contacts with prospective students, creating linkages with historical institutions of color, having (or approached having) a critical mass of faculty and students of color, offering a diversity issues course, and engaging students in diversity issues research. Despite the similarities, the programs and departments were each distinctive and innovative in their overall approaches to student recruitment and retention. Highlighting the strategies used at successful institutions may help others develop plans for improving the minority pipeline within their own departments and programs.     

Response to commentary on the multimodal treatment study of ADHD (MTA): mining the meaning of the MTA

In the December 2000 issue of the Journal of Abnormal Child Psychology, we published a set of papers presenting secondary analyses of the Multimodal Treatment Study of ADHD (MTA), and R. A. Barkley (2000) provided a commentary. A critique of the design of the study (MTA Cooperative Group, 1999) was presented based on a theoretical perspective of a behavioral inhibition deficit that has been hypothesized as the core deficit of ADHD (R. A. Barkley, 1997). The commentary questioned the design and analysis of the MTA in terms of (1) the empirical criteria for selection of components of behavioral (Beh) intervention, (2) the effectiveness of the Beh intervention, (3) the methods for analyses at the group and individual level, (4) implications of the MTA findings for clinical practice, (5) the role of genetics in response to treatment, and (6) the lack of a nontreatment control group. In this response, we relate the content of the papers to the commentary, (1) by reviewing the selection criteria for the Beh treatment, as outlined by K. C. Wells, W. E. Pelham, et al. (2000), (2) by addressing the myth that the MTA Beh treatment was ineffective (Pelham, 1999), (3) by describing the use of analyses at the level of the individual participant, as presented by J. S. March et al. (2000) and W. E. Pelham et al. (2000) as well as elsewhere by J. M. Swanson et al. (2001) and C. K. Conners et al. (2001), (4) by relating some of the suggestions from the secondary analyses about clinically relevant factors such as comorbidity (as presented by J. S. March et al., 2000) and family and parental characteristics (as presented by B. Hoza et al., 2000, S. P. Hinshaw et al., 2000, and K. C. Wells, J. N. Epstein, et al., 2000), (5) by discussing the statistical concept of heritability and the lack of a significant difference in the presence of ADHD symptoms in parents of the MTA families compared to parents in the classmate-control families (as presented by J. N. Epstein, et al., 2000), and (6) by acknowledging that an ethically necessary weakness of the MTA design is that it did not include a no-treatment control group. We discuss the use of secondary analyses to suggest how, when, and for what subgroups effectiveness of the Beh treatment may have been manifested. Finally, we invite others to use the large and rich data set that will soon be available in the public domain, to perform secondary analyses to mine the meaning of the MTA and to evaluate theories of ADHD and response to treatments.     

Deeper processing at target selection increases the magnitude of negative priming

Do deeper levels of processing produce equivalent priming effects at all stages of task performance? In Experiment 1, we varied the level of processing factorially across two task stages—target selection and response selection. Each stage required perceptual (e.g., color) or conceptual (e.g., friendliness) processing of stimulus items (i.e., animal names). Negative priming was substantially greater when deeper processing was required at thetarget selection stage, but it was unaffected by the level of processing at the response selection stage. In contrast, positive priming was greater when deeper processing was required at theresponse selection stage, but it was unaffected by processing at the target selection stage. In Experiment 2, we generalized this finding using a task in which numeric targets were selected on the basis of their parity. As in Experiment 1, the deeper level of processing at the target selection stage produced a larger negative priming effect. These results illuminate the role of target selection demands in modulating the strength of negative priming.     

College women's career and motherhood expectations: New options,old dilemmas

Gender differences in spatial ability in old age were examined longitudinally and the effectiveness of cognitive training in reducing these differences was assessed. The mental rotation ability of older participants (N=229; M age=72.8 years) from the Seattle Longitudinal Study was examined over a 14-year period (1970–1984) from late middle age into old age. Both men and women exhibited normative age-related decline in spatial ability performance across the 14-year period; the magnitude of the gender difference remained constant across this period of decline. A significantly greater proportion of the age-related decline was associated with a drop in speed of problem solving for men than for women. Following training on mental rotation ability, there was no significant gender difference in spatial ability performance. Women exhibited significantly greater pretest-posttest gains, on average, than did men. A greater proportion of training improvement for women compared to men was attributable to increased accuracy. Training was particularly effective for older women who had experienced prior age-related decline.The research reported in this article was supported by grant no.

Acute alcohol intoxication paired with aversive reinforcement: ethanol odor as a conditioned reinforcer in rat pups

Previous research has suggested that infant rats process ethanol sensory properties during acute alcohol intoxication. The present study was designed in order to examine if alcohol odor could act as an aversive conditioned stimulus after the organism experiences the state of intoxication paired with nociceptive stimulation (footshock). In a first experiment 11-day-old pups received intragastric alcohol administration (1.5 g/kg). At different postabsorptive intervals footshock was presented (0-30, 30-60, 60-90, or 90-120 min). An explicitly unpaired control group which experienced footshock prior to the state of intoxication was also employed. All animals were subsequently tested in terms of alcohol intake and ethanol locational odor preferences. Both assessments indicated that pups which were exposed to the unconditioned peripheral stimulus 30-60 min after receiving ethanol expressed strong alcohol aversions. In a second experiment pups were exposed to footshock during this postabsorptive interval. Twenty four hours later, pups experienced ambient ethanol odor paired with soft or rough texture surfaces. Differential texture aversions were registered in experimental animals when compared with controls which suffered the state of intoxication explicitly unpaired with footshock, or unpaired presentations of ethanol odor and the tactile stimuli under consideration. These results appear to support the hypothesis concerning orosensory processing during an acute state of intoxication. Additionally it seems that the hedonic value of sensory attributes of this drug varies as a function of associative processes occurring during such a state.     

Perfectionism,Components of Stress Reactivity,and Depressive Symptoms

The current study examined the associations among dimensions of perfectionism, facets of stress reactivity, and self-reported depressive symptoms in 191 university students. Participants completed the Multidimensional Perfectionism Scale, the Perfectionism Cognitions Inventory, the Perceived Stress Reactivity Scale (PSRS), and a measure of depressive symptoms. The PSRS is a relatively new instrument that measures several distinguishable facets of stress reactivity including prolonged stress reactivity, reactivity to failure, and reactivity to social evaluation. Analyses confirmed that most of the perfectionism measures were associated with stress reactivity to failure experiences. Socially prescribed perfectionism and perfectionistic automatic thoughts were also associated with prolonged stress reactivity and reactivity to social evaluation. Moreover, all facets of stress reactivity were correlated with depressive symptoms. Finally, prolonged stress reactivity and reactivity to social evaluation mediated the links between perfectionism dimensions and depressive symptoms. The current findings provide general support for models of perfectionism and stress, and suggest that perfectionists have heightened sensitivities to stressors related to their self-definitions that are activated when threatening stressors involving these themes are experienced.     

Meaning gained versus meaning lost: The effects of meaning salience on anxiety and depression during the coronavirus pandemic

People who have meaningful lives generally experience less anxiety and depression. Meaning salience, or the awareness of the meaning in one's life, is believed to partially explain this relationship. However, in times of isolation, what might be most salient to people are the meaningful aspects of their lives that have disappeared. This study seeks to understand how making gained versus lost meaning salient affects anxiety and depression. Participants either wrote for 5 minutes about how their life gained meaning (n = 29) or lost meaning (n = 30) due to the coronavirus restrictions, or about music (i.e., the control condition; n = 32). Those who wrote about gained meaning experienced less momentary anxiety than those who wrote about lost meaning. In addition, meaning salience moderated the relationship between meaning and both anxiety and depression. Those who wrote about gained meaning appeared to exhibit a positive relationship between meaning in life (MIL) and both anxiety and depression, while those who wrote about lost meaning exhibited negative relationships. In all, this suggests that meaning salience is not always positive and that researchers and practitioners should consider how making positive meaning salient may be more beneficial than a general focus on MIL.
