Emotional arousal and memory: a test of the poststimulus processing hypothesis

Emotional arousal is believed to enhance memory for details central to an episode but impair memory for peripheral details. However, new research suggests that arousal induced thematically (i.e., through involvement with an unfolding event) produces only memory enhancements. This article examines whether consciously controlled elaborative processing in the aftermath of an arousing experience is responsible. A dual task manipulation was used to prevent participants from ruminating over a video that depicted an abduction and attack. Several indices of recall showed greater memory for emotional event details than for details from a neutral control video, which remained the case when the opportunity for post-stimulus elaboration was prevented. Thus, superior retention of the content of emotional experiences may arise from the way in which arousal is induced rather than through immediate postevent cognitions.     

Temperament and Psychopathy: A Dual-Pathway Model

ABSTRACT— The concept of psychopathy refers to a pattern of chronic antisocial behavior and personality features, such as emotional detachment, lovelessness, and guiltlessness, attributable in part to a temperament deficit. Historically, that deficit has been seen as a low reactivity to fear, but recent research has documented a second temperament deficit in adults that involves poor emotional and behavioral control. Both pathways are found in the child psychopathology literature, pointing to multifactorial developmental pathways from childhood to adult psychopathy.     

Effects of menstrual cycle phase on aggression measured in the laboratory

This study investigated the effects of menstrual cycle phase on aggression in two groups of women, which differed in the severity of their self-reported perimenstrual symptoms. A low- and a high-symptom group were recruited using the Menstrual Distress Questionnaire (MDQ) to define the groups. Twenty-two subjects (11 low and 11 high symptom) participated across one menstrual cycle: during the premenstrual, menstrual, midfollicular, and ovulatory phases. The Point Subtraction Aggression Paradigm was used to assess aggression on each day of participation. There were three main findings; a) rates of aggressive responding did not vary across phases of the menstrual cycle; b) the high-symptom group emitted higher rates of aggressive responding across the menstrual cycle than did the low-symptom group; and c) rates of aggressive responding correlated with the MDQ's behavioral and psychological scales and not the somatic scales. These findings indicate that the menstrual cycle phase does not differentially affect this laboratory measure of aggression. The differences found between the two symptom groups parallel a few reports indicating that women who differ in retrospectively reported mood and behavioral changes related to their menstrual cycle also differ on a number of other psychometric measures.

The survival and developmental outcome of extremely low birthweight infants

The purpose of this retrospective study is to compare the factors affecting the survival and developmental outcome of extremely low birthweight infants (ELBW; < 1,001 gms.). One hundred and forty of two hundred and twenty-three ELBW neonates (63%) from two Level III NICUs born between 1986 and 1988 survived until discharge. Lower birthweight, 5-minute Apgar ≤ 3, and no administration of surfactant were the best predictors of infant mortality as assessed via logistic regression (correct classification = 78%). The functioning of 34 of these infants was assessed at approximately 18 months of age with the Bayley Scales of Infant Development. Mean performance on the Mental Development Index (MDI) was 88.65 ± 21.75, with 35.3% and 20.6% of infants scoring, respectively, I (< 85) and 2 (< 70) standard deviations below the mean. Given survival, intraventricular hemorrhage (IVH, Grade III or IV) was the best predictor of MDI performance as assessed via stepwise multiple regression (adjusted R²=.23). Cerebral palsy affected one fifth of the sample and was also best predicted by IVH. Discussion focuses on the conceptual and practical implications of the finding that infant survival and infant developmental status were associated with different factors.     

Self‐reference and group membership: evidence for a group‐reference effect

Two experiments were designed to explore whether encoding information in reference to a group would facilitate the later recall of that information to the same extent as encoding with reference to the self. In both experiments, participants encoded adjectives with reference to the self, semantic properties, or a group and were subsequently given a surprise‐free recall test. In Experiment 1 (N = 37), the participants' university served as the reference group. In Experiment 2 (N=41), the participants' family served as the reference group. In both experiments, self‐reference resulted in better recall than semantic processing, replicating the typical self‐reference effect (SRE). More importantly, strong evidence for a group‐reference effect (GRE) was found in that group‐reference resulted in better recall than semantic processing and in fact facilitated recall to the same extent as self‐referencing. The existing explanations (schemas, organization, elaboration, mental cueing, and evaluation) for the SRE were compared with regard to their viability in accounting for the GRE patterns. We discuss additional features that may be important in the explanation of the SRE and suggest future directions for research on group‐referencing. Copyright © 2002 John Wiley & Sons, Ltd.     

Is the DOSPERT gender invariant? A psychometric test of measurement invariance

It is well established in the risk literature that men tend to take more risks than women. This gender difference, however, is often qualified by its domain specificity. Considering recent research on the domain generality of risk taking as a disposition, there is a need to examine the degree to which men take more risks than women, in general. In order to make substantive conclusions about the gender differences in risk‐taking propensity, one must first establish measurement invariance, which is required for the meaningful interpretation of observed group differences. In this paper, we examined the measurement invariance of the Domain‐Specific Risk‐Taking scale (DOSPERT)—one of the most popular measures of individual differences in risk taking. We found that the DOSPERT violated configural invariance in a bifactor model, indicating that the underlying factor structure of the DOSPERT differs between men and women. Even after removing the social risk dimension, DOSPERT still failed to reach scalar invariance. Taken together, these findings suggest that score differences in the DOSPERT may be due to response artifacts rather than true differences in the latent construct. Therefore, gender differences in the DOSPERT must be interpreted with caution. Implications for the measurement of risk taking are discussed.     

Telling stories to communicate the value of the pre‐employment structured job interview

In an effort to bridge the scientist–practitioner gap in the employee selection, some researchers have advocated telling stories to better communicate the value of evidence‐based hiring practices to human resource (HR) professionals. In this paper, we conducted two experiments that examine the efficacy of storytelling for overcoming managers’ resistance to use structured job interviews. In two experiments, we found that participants who read a story regarding the effectiveness of structured interviews, as opposed to receiving evidence‐based advice, reported more favorable attitudes toward structured job interviews. Serial mediation analysis revealed that the observed attitude change was mediated by an increase in narrative transportation and reduction in counterarguing. Implications for using stories in communicating the value of evidence‐based HR practices are discussed.     

Emotional Support from Parents and In-Laws: the Roles of Gender and Contact

After the birth of a child, new mothers and fathers commonly have a substantial amount of contact with their parents and in-laws. However, this contact may not always result in emotional support. We tested if contact, rather than geographical distance, influenced emotional support received from parents and in-laws and whether there were gender differences in these associations. Online questionnaire data were collected in 2008 from a community sample of U.S. first-time mothers (n?=?93) and fathers (n?=?93) who were in a heterosexual relationship and living together. Results indicated that for new mothers, greater contact with own parents and in-laws was related to receiving more emotional support. However, for mothers, greater contact with parents also was related to less emotional support from in-laws. For new fathers, contact was not related to emotional support from either parents or in-laws. These findings suggest that receiving support as a result of contact with family members may be gendered, particularly for new mothers’ and fathers’ relationships with their in-laws. The current study highlights the importance of reducing stigmas about men and their emotional needs and of encouraging new fathers to seek and receive support from family during the transition to parenthood.     

Attachment avoidance to God exacerbates the negative effect of tangible resource loss on psychological resource loss

The present study examined the impact of losing tangible resources on psychological resources in a sample of college students (n?=?160) affected by Hurricane Katrina. The data was collected approximately five months after the storm. Based on conservation of resources theory, we tested whether the loss of tangible resources (e.g., food, water) would be positively related to the loss of psychological resources (e.g., optimism, hope), and whether this association would be exacerbated by having an insecure (anxious or avoidant) attachment to God. As predicted, loss of tangible resources was related to the loss of psychological resources, and this relationship was amplified in participants who had an avoidant attachment to God. We conclude by discussing implications of the present study and areas for future research.
