The internal working models concept: What do we really know about the self in relation to others?

The internal working models concept is the foundation for understanding how attachment processes operate in adult relationships, yet many questions exist about the precise nature and structure of working models. To clarify the working models concept, the authors evaluate the empirical evidence relevant to the content, structure, operation, and stability of working models in adult relationships. They also identify 4 theoretical issues that are critical for clarifying the properties of working models. These issues focus on the central role of affect and goals in working models, the degree to which working models are individual difference or relational variables, and the definition of attachment relationships and felt security in adulthood.

Designing a safer workplace: Importance of job autonomy, communication quality, and supportive supervisors.

The direct and indirect effects of work characteristics on self-reported safe working were investigated in a longitudinal study of frontline manufacturing employees (N?=?161). The work characteristics included job autonomy, role overload, role conflict, supportive supervision, training adequacy, job security, and communication quality. Job autonomy and communication quality were positively associated with safe working after prior levels of these variables were controlled for, and supportive supervision had a lagged positive effect on safe working 18 months later. Additional analyses showed that organizational commitment fully mediated the effect of job autonomy on safe working and partially mediated the effect of communication quality on safe working. The study suggests that work characteristics are important antecedents of safe working. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Countertransference, attachment, and the working alliance: The therapist's contribution.

This study examined the relationship among therapist attachment styles, countertransference behaviors, and working alliance. Fifty therapists in training and their supervisors participated in the study. Therapists completed a self-rated measure of attachment style and a measure of working alliance with 1 of their clients. Supervisors completed measures of working alliance and countertransference behaviors about their supervisee's relationship with the same client. Results indicate that therapist attachment style did not correlate with either countertransference behaviors or working alliance. However, negative countertransference was associated with poorer working alliances, and positive countertransference was related to a weak bond within the working alliance. Additional analyses indicate that disagreement among supervisors and therapists about the bond component was predictive of countertransference behaviors.

Divergent trajectories in the aging mind: Changes in working memory for affective versus visual information with age.

Working memory mediates the short-term maintenance of information. Virtually all empirical research on working memory involves investigations of working memory for verbal and visual information. Whereas aging is typically associated with a deficit in working memory for these types of information, recent findings suggestive of relatively well-preserved long-term memory for emotional information in older adults raise questions about working memory for emotional material. This study examined age differences in working memory for emotional versus visual information. Findings demonstrate that, despite an age-related deficit for the latter, working memory for emotion was unimpaired. Further, older adults exhibited superior performance on positive relative to negative emotion trials, whereas their younger counterparts exhibited the opposite pattern.

Do the contents of visual working memory automatically influence attentional selection during visual search?

In many theories of cognition, researchers propose that working memory and perception operate interactively. For example, in previous studies researchers have suggested that sensory inputs matching the contents of working memory will have an automatic advantage in the competition for processing resources. The authors tested this hypothesis by requiring observers to perform a visual search task while concurrently maintaining object representations in visual working memory. The hypothesis that working memory activation produces a simple but uncontrollable bias signal leads to the prediction that items matching the contents of working memory will automatically capture attention. However, no evidence for automatic attentional capture was obtained; instead, the participants avoided attending to these items. Thus, the contents of working memory can be used in a flexible manner for facilitation or inhibition of processing. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
