The putative association between fear-related behaviors and peripheral sympathetic and neuroendocrine reactivity has not been replicated consistently. This inconsistency was addressed in a reexamination of the characterization of children with extreme fearful reactions by focusing on the match between distress behaviors and the eliciting context.…

The authors offer a framework for conceptualizing collective identity that aims to clarify and make distinctions among dimensions of identification that have not always been clearly articulated. Elements of collective identification included in this framework are self-categorization, evaluation, importance, attachment and sense of interdependence,…

In everyday tasks, selecting actions in the proper sequence requires a continuously updated representation of temporal context. Previous models have addressed this problem by positing a hierarchy of processing units, mirroring the roughly hierarchical structure of naturalistic tasks themselves. The present study considers an alternative framework,…

This research utilizes longitudinal data from newly married couples to investigate change in perceptions of role-taking accuracy over time. It is suggested that when individuals feel they can understand their spouse's perspective, they will be more likely to be aware of how their behavior will affect the spouse; as a result, they will be more…

Early theoretical work on social exchange focused on how exchange relations generate social structural outcomes. Specifically, gift giving was said to evoke status structures. No experimental evidence exists to verify or refute the notion that gift giving during exchange processes generates status hierarchies. We present experimental results…

Offers the view that learning in organizations is mainly a social activity because work is most often done by people in the context of communicating with others. Briefly assesses how learning can be managed in organizations.

What role does contextual information play in children's early word comprehension? Using an inter-modal preferential looking task, we investigated how different background contexts influence children's looking times before and after an image has been named. Prior to the experiment, early comprehension of words was assessed using parental…

Two experiments examined the effect of age and cognitive demands on children's choice strategies. Children aged 8-9 and 12-13 years were asked to choose among either two or four products that differed in several attributes of varying importance to them. Choice tasks were designed to differentiate between the lexicographic and the equal-weighting…

Theorists suggest that gender differences in moral reasoning are due to differences in the self-concept, with women feeling connected to others and using a care approach, whereas men feel separate from others and adopt a justice approach. Using a self-categorization analysis, the current research suggests that the nature of the self-other…

Long-term memory formation is regulated by many distinct molecular mechanisms that control gene expression. An emerging model for effecting a stable, coordinated pattern of gene transcription involves epigenetic tagging through modifications of histones or DNA. In this study, we investigated the regulation of histone phosphorylation in the…

Using pharmacological techniques, it has been demonstrated that both consolidation and extinction of Pavlovian fear conditioning are dependent to some extent upon L-type voltage-gated calcium channels (LVGCCs). Although these studies have successfully implicated LVGCCs in Pavlovian fear conditioning, they do not provide information about the…

We report that post-training inactivation of basolateral amygdala region (BLA) with muscimol impaired memory for contextual-fear conditioning (as measured by freezing) and intra-BLA norepinephrine enhanced this memory. However, pre-exposure to the context eliminated both of these effects. These findings provide a likely explanation of why an…

The editors give each of the theorists a chance to respond to questions posed about the context of the situation in relation to their own experience in the field, exploring how the exercise had an impact on their evaluation designs.

Meaning activation was estimated during (standard naming) and after (delayed naming) target presentation to chart the time course of priming effects during reading comprehension. Using sentences biasing homographs toward their dominant and subordinate meanings, two experiments evaluated context effects across three naming-cue delays: immediate,…

In 3 experiments, 3-month-old infants were trained to move an overhead mobile by kicking 1 of their feet in the presence of a distinctive visual (crib bumpers) and auditory (music) context. In Experiment 1A, 5-day but not 1-day retention was disrupted if either or both elements of the context present during the retention test were novel. In…
