ReviewMultilevel modeling: current and future applications in personality research.
Traditional statistical analyses can be compromised when data are collected from groups or multiple observations are collected from individuals. We present an introduction to multilevel models designed to address dependency in data. We review current use of multilevel modeling in 3 personality journals showing use concentrated in the 2 areas of experience sampling and longitudinal growth. ⋯ We consider issues that may arise in estimation, model comparison, model evaluation, and data evaluation (outliers), highlighting similarities to and differences from standard regression approaches. Finally, we consider newer developments, including 3-level models, cross-classified models, nonstandard (limited) dependent variables, multilevel structural equation modeling, and nonlinear growth. Multilevel approaches both address traditional problems of dependency in data and provide personality researchers with the opportunity to ask new questions of their data.

ReviewSelf-regulation and personality: how interventions increase regulatory success, and how depletion moderates the effects of traits on behavior.
Self-regulation is a highly adaptive, distinctively human trait that enables people to override and alter their responses, including changing themselves so as to live up to social and other standards. Recent evidence indicates that self-regulation often consumes a limited resource, akin to energy or strength, thereby creating a temporary state of ego depletion. This article summarizes recent evidence indicating that regular exercises in self-regulation can produce broad improvements in self-regulation (like strengthening a muscle), making people less vulnerable to ego depletion. Furthermore, it shows that ego depletion moderates the effects of many traits on behavior, particularly such that wide differences in socially disapproved motivations produce greater differences in behavior when ego depletion weakens the customary inner restraints.

ReviewCoping through emotional approach: a new look at emotion, coping, and health-related outcomes.
Researchers studying stress and coping processes have attempted to identify which coping strategies are most adaptive in stressful encounters. A generally accepted conclusion has been that emotion-focused coping processes are associated with dysfunctional outcomes. Studies from our and other research teams challenge the "bad reputation" of emotion-focused coping by demonstrating that items measuring emotion-focused strategies in published coping questionnaires are confounded with distress and self-deprecation. ⋯ Longitudinal and experimental studies using these new scales have documented the adaptive potential of emotional-approach coping in the context of several types of stressors, including infertility, breast cancer, and chronic pain. However, characteristics of the environmental context, stressful experience, and individual are important moderators of the relations of emotional-approach coping and health-related outcomes. Potential mediators and moderators of coping through emotional approach, clinical relevance of the construct, and directions for research are discussed.

ReviewBiological bases of extraversion: psychophysiological evidence.
There is a good deal of evidence, particularly from electrodermal and electrocortical recording procedures, that introverts exhibit greater reactivity to sensory stimulation than extraverts. There is little evidence that introverts and extraverts differ in base level of arousal in neutral conditions, and there is no clear evidence that their differences in sensitivity to stimulation are determined by differences in attentional state. Faster auditory brainstem evoked response latencies observed for introverts implicate differences in peripheral sensory processes that are not determined by mechanisms in the reticular system as proposed in the arousal hypothesis. There is also evidence that individual differences in the expression of motor activity between introverts and extraverts involve differences in motoneuronal excitability.
