Configural Approaches to Temperament Assessment: Implications for Predicting Risk of Unintentional Injury in Children

ABSTRACT This study used two configural approaches to understand how temperament factors (surgency/extraversion, negative affect, and effortful control) might predict child injury risk. In the first approach, clustering procedures were applied to trait dimensions to identify discrete personality prototypes. In the second approach, two- and three-way trait interactions were considered dimensionally in regression models predicting injury outcomes. Injury risk was assessed through four measures: lifetime prevalence of injuries requiring professional medical attention, scores on the Injury Behavior Checklist, and frequency and severity of injuries reported in a 2-week injury diary. In the prototype analysis, three temperament clusters were obtained, which resembled resilient, overcontrolled, and undercontrolled types found in previous research. Undercontrolled children had greater risk of injury than children in the other groups. In the dimensional interaction analyses, an interaction between surgency/extraversion and negative affect tended to predict injury, especially when children lacked capacity for effortful control.     

Different patterns of contingent stimulation differentially affect attention span in prelinguistic infants

The ability to sustain attention influences different domains including cognitive, motor, and communicative behavior. Previous research has demonstrated how an infant's parent can influence sustained attention. The purpose of our study was to expose infants systematically to both sensitive and redirective patterns of behavior to examine how unfamiliar individuals could influence attention. Results revealed infants changed their patterns of looking with the unfamiliar individuals. Infants had longer durations of sustained attention when interacting with a sensitive unfamiliar individual who followed into their attentional focus as opposed to an intrusive person who led their attentional focus. This study demonstrates that infants discriminate patterns of contingency to persons seen for only a short period of time broadening the range of potential mentors for learning.     

ROMANTIC PARTNERS' COPING STRATEGIES AND PATTERNS OF CORTISOL REACTIVITY AND RECOVERY IN RESPONSE TO RELATIONSHIP CONFLICT

Stress in close relationships can have significant negative consequences for mental health, physical health, and long-term relationship functioning. Dysregulated physiological responses to stress are potential pathways through which relationship stress may lead to these kinds of outcomes, and the ways in which individuals attempt to cope with relationship stress are likely to impact their physiological responses. However, our understanding of the specific coping strategies that predict physiological reactivity and recovery in these contexts is rather limited. This study explored relations between young adult college students' self-reported methods of coping with stress in their romantic relationships and their physiological reactivity to and recovery from negotiating conflict with their romantic partners. Partners' coping styles were also examined as predictors of physiological stress responses. One hundred and ninety opposite-sex couples (N = 380; modal length of relationship = 1-2 years) participated in an experimental conflict discussion task. Physiological stress reactivity to the task was assessed using salivary cortisol, a primary hormonal product of the hypothalamic-pituitary-adrenocortical (HPA) axis. Growth modeling of the cortisol levels before, during, and after the conflict task indicated that men who typically coped with relationship stress by seeking social support showed greater physiological reactivity to the conflict task. Partners' need for social support predicted stronger stress responses for both men and women, as well. While seeking social support is generally thought to be an adaptive coping strategy for couples, the results suggest that within the context of conflict negotiation in which receiving and providing support may be more difficult, seeking support from a partner is associated with greater phyisological stress.     

The Moderating Effect of Personality on Employees’ Reactions to Procedural Fairness and Outcome Favorability

Purpose  

The purpose of this study was to examine how personality moderates the interactive effect of procedural fairness perceptions and outcome favorability on employees’ job attitudes.     

Remembering words not presented in lists: Can we avoid creating false memories?

Can subjects avoid creating false memories as outlined in Roediger and McDermott’s (1995) false recognition paradigm if they are forewarned about this memory illusion? We presented subjects with semantically related word lists, followed by a recognition test. The test was composed of studied words, semantically related nonstudied words (critical lures), and unrelated nonstudied words. One group of subjects was uninformed about the false recognition effect, a second group was urged to minimize all false alarms, and a third group was forewarned about falsely recognizing critical lures. Compared with the uninformed and cautious subjects, the forewarned subjects reduced their false alarm rate for critical lures, and they made remember and know judgments equally often for recognized studied words and critical lures. But forewarning did not eliminate the false recognition effect, as these subjects and those in the other groups made numerous false recognitions in this task.     

Implicit synthesis

In this reply to Neal and Hesketh and to the commentators, we argue that implicit knowledge is partly abstract and can be usefully defined by the criteria of both metaknowledge and intentional control. We suggest that the pattern of dissociations supports a claim of separate implicit and explicit learning modes. According to our characterization, implicit learning leads to knowledge that is not automatically represented as knowledge by the learning process; instead, the presence of knowledge has to be inferred by the subject (partial explicitation) if metaknowledge is gained at all. During explicit learning, knowledge is automatically labeled as knowledge by the learning process, so that metaknowledge comes immediately and to the fullest extent. Finally, we suggest that implicit knowledge may to some degree apply regardless of intention.     

Detection of random responding on the MMPI-A

We examined random responding on the MMPI-A in 106 adolescents from the general population. Participants were asked to report on the frequency, location, and reasons for any random responses occurring during a standard administration of the MMPI-A. Relationships between self-reported random responding and validity indices (F1, F2, F, and Variable Response Inconsistency [VRIN] scale) were examined. In addition, each participant was randomly assigned to 1 of 5 groups, with each group completing an assigned portion (0, 25%, 50%, 75%, or 100%) of an MMPI-A answer sheet without access to the test booklet, and the utility of the validity scales in discriminating standard protocols from all or partially random protocols was investigated. Most adolescents acknowledged one or more random responses correlated significantly with F but not VRIN. Validity scales were sensitive to all or partially random protocols, and produced high classification rates when discriminating among groups.
