The psychosocial impact of Hurricane Katrina: contextual differences in psychological symptoms, social support, and discrimination

This study tested a contextual model of disaster reaction by examining regional differences in the psychosocial impact of Hurricane Katrina. A total of 386 individuals participated in this study. All were recruited in the primary areas affected by Hurricane Katrina and included residents of metropolitan New Orleans (Orleans Parish, Louisiana), Greater New Orleans (i.e., Metairie, Kenner, Gretna), and the Mississippi Gulf Coast (i.e., cities along the coast from Waveland to Ocean Springs, Mississippi). Participants were assessed for posttraumatic stress disorder (PTSD) symptoms, other psychological symptoms, perceptions of discrimination, perceptions of social support, evacuation distance, and the extent to which they experienced hurricane-related stressful events. Results were consistent with previous research on the impact of disasters on mental health symptoms. Findings extended research on individual differences in the response to trauma and indicated that regional context predicted unique variance in the experience of discrimination, social support, and emotional symptoms consistent with the theoretical model presented.     

Effect of preconditioning unconditioned stimulus experience on learned taste aversions.

One taste-aversion study using male Long-Evans rats in which ethanol was the unconditioned stimulus (UCS) and six studies in which lithium chloride (LiCl) was the UCS demonstrate that (a) exposure to the UCS prior to conditioning retards subsequent acquisition of learned taste aversions; (b) a single preconditioning UCS exposure is sufficient to attenuate conditioning; (c) the preconditioning UCS exposure must occur within a limited period prior to conditioning to attenuate learning; (d) repeated conditioning trials will override the effect of prior exposure to the UCS; (e) tolerance to the UCS is not a necessary condition for the attenuation effect to occur; (f) pairing the preconditioning UCS with a novel flavor other than the CS does not remove the preexposure effect, although it may reduce its magnitude; and (g) the degree of disruption is a positive function of preconditioning UCS dosage and an inverse function of conditioning UCS dosage.     

Preschoolers' magnitude comparisons are mediated by a preverbal analog mechanism

We report a study of 3- to 5-year-olds who performed a magnitude-comparison task. Stimuli were a series of pairs of arrays that sometimes differed in numerosity, and the children were asked to point to the more numerous array in each pair. The proportion of accurate responses was above chance for all age groups. However, error patterns were consistent with analog models of magnitude representation. Errors varied systematically with the ratio of stimulus pairs. Items with a 2:3 ratio were harder than items with a 1:2 ratio. Performance on posttests of verbal counting ability was variable, but did not predict performance on the numerical discrimination task. We argue that neither verbal counting nor nonnumerical perceptual strategies can explain these results. This study supports the hypothesis that adults and children share preverbal, analog representations of magnitude.     

Mentoring in the Academic Medical Setting: The Gender Gap

Mentoring is an essential part of success in the academic medical center. The provision of effective mentoring is key to the success of the increasing numbers of women entering medicine. However, the gender distribution within the hierarchy of medicine has not changed in that the power still resides with men in the system. Currently, men are attempting to mentor women, and so as the proportion of women in medicine continues to grow, they will become more influential in this setting and will become increasingly responsible for providing mentoring to men. In either case, effective communication across gender lines is an essential aspect of the mentoring process. Psychologists in academic medical settings can provide guidance to faculty and staff on the critical aspects of social development and communication, which may affect how women and men are mentored and the success of this mentoring process, whether across or within gender lines.     

Cardiac response as an index of the effect of aversion therapy

Recent research shows that aversion conditioning produces conditioned aversions to target stimuli. Conditioned aversions are manifest in the following posttreatment changes in Ss' responses to target stimuli: increased negative evaluations, decreased contact or consumption, and increased phasic heart-rate responses (HRRs). Research on aversion therapy for additive disorders reveals that HRR is a particularly important index of therapeutic change as it is predictive of latency to relapse to drug use. We speculate that aversion conditioning increases Ss' fear and repugnance of target stimuli, that HRRs accurately reflect such defensive responses and that magnitude of defensive response is positively related to latency to relapse. In addition to defensive responding, we believe that HRRs may reflect coping-response or active-avoidance information processing.     

The PHQ-9 as a brief assessment of lifetime major depression

The Patient Health Questionnaire-9 (PHQ-9; R. L. Spitzer, K. Kroenke, J. B. W. Williams, & The Patient Health Questionnaire Primary Care Study Group, 1999), modified to ask about the worst period of depression lifetime, was validated against lifetime mood disorder diagnoses established by the Structured Clinical Interview for DSM-IV (SCID; M. B. First, R. L. Spitzer, M. Gibbon, & J. B. W. Williams, 2001) in 526 participants. PHQ-9 dichotomous scores corresponded highly with major depressive episode (MDE) Criterion A, MDE, and major depressive disorder (MDD), odds ratios >or= 9.5, and area under the receiver operating characteristic curve (AUC) >or= 0.84. The continuous scale score was higher in participants who did (M=17.14, SD=7.36) than in those who did not (M=6.05, SD=6.29) meet MDE Criterion A, t(524)=18.09, p<.001; was correlated with number of MDE Criterion A symptoms, r(525)=.67, p<.001; and detected MDE Criterion A (AUC=0.88). The PHQ-9 as a lifetime measure may be used to complement or replace more costly interview assessments.     

Birth Weight and Childhood Psychopathology in the ABCD Cohort: Association is Strongest for Attention Problems and is Moderated by Sex

Research on Child and Adolescent Psychopathology - Many studies have shown low birth weight is associated with psychopathology later in life, particularly attention-deficit/hyperactivity disorder...     

Key Accounts and Team Selling: A Review,Framework, and Research Agenda

As sales organizations increase their reliance on sales teams, they must learn how organizational and interpersonal relationships influence sales teams, how sales teams play a learning role for organizations, and what makes sales teams effective. Presenting a model of interrelationships among members of the selling firm and between the selling and buying firms, we identify five key team selling relationships between (1) members of the same team, (2) members of different teams within the firm, (3) the selling team and the buying center, (4) the selling team and other groups in the selling firm, and (5) the selling team and the firm’s strategy. This model leads to a conceptual framework highlighting relationship drivers, factors, and outcomes instrumental to team selling success. After presenting propositions for future research, theoretical and methodological suggestions are included to facilitate research in this area. We conclude with perspectives on the future of research and practice in key accounts and team selling.
