Relationships among team ability composition, team mental models, and team performance

This study examined the relationship between the similarity and accuracy of team mental models and compared the extent to which each predicted team performance. The relationship between team ability composition and team mental models was also investigated. Eighty-three dyadic teams worked on a complex skill task in a 2-week training protocol. Results indicated that although similarity and accuracy of team mental models were significantly related, accuracy was a stronger predictor of team performance. In addition, team ability was more strongly related to the accuracy than to the similarity of team mental models and accuracy partially mediated the relationship between team ability and team performance, but similarity did not.     

Surface location and enclosure

This research addressed the issue of whether impressions of enclosure were more strongly influenced by amount of view covered by vertical boundaries (H1) or the presence of a boundary overhead (H2). There were three studies with totals of 48 stimuli and 142 respondents. Stimuli were balconies, swamps, and space stations. Effect sizes were reported for variables of boundaries below, in front of, and at the observers' sides, as well as amount of view covered by any boundary regardless of location with respect to the observer. Judged enclosure correlated at r =.80 for amount of view covered by vertical boundaries and r =.42 with the presence or absence of boundaries overhead, indicating that enclosure is more strongly related to vertical rather than overhead boundaries (alpha< .001).     

HISTORICAL ASPECTS OF MINDFULNESS AND SELF-ACCEPTANCE IN PSYCHOTHERAPY

We describe some of the historical conditions that made possible Kabat-Zinn’s [(1990). Full catastrophe living: Using the wisdom of your body and mind to face stress, pain, and illness. New York: Delacorte] very successful use of mindfulness in his stress management program. The ground had been prepared by the nonjudgmental acceptance of people and symptoms by Humanistic psychotherapists, and by the increasing assimilation of Buddhist ideas into Western psychology and psychotherapy. In addition the word “mindfulness,” as the translation of the Pali sati, came to refer to both the manualized practice that provides the evidence for its efficacy in the hands of Kabat-Zinn and others, and the more complex process of clear comprehension and recollection that is described in his more discursive writings, and is similar to Ellen Langer’s use of “mindfulness” in her book of that name.

Visual search for real world targets under conditions of high target-background similarity: Exploring training and transfer in younger and older adults

Real world visual search tasks often require observers to locate a target that blends in with its surrounding environment. However, studies of the effect of target-background similarity on search processes have been relatively rare and have ignored potential age-related differences. We trained younger and older adults to search displays comprised of real world objects on either homogenous backgrounds or backgrounds that camouflaged the target. Training was followed by a transfer session in which participants searched for novel camouflaged objects. Although older adults were slower to locate the target compared to younger adults, all participants improved substantially with training. Surprisingly, camouflage-trained younger and older adults showed no performance decrements when transferred to novel camouflage displays, suggesting that observers learned age-invariant, generalizable skills relevant for searching under conditions of high target-background similarity. Camouflage training benefits at transfer for older adults appeared to be related to improvements in attentional guidance and target recognition rather than a more efficient search strategy.     

The functions of nonsuicidal self-injury: support for cognitive-affective regulation and opponent processes from a novel psychophysiological paradigm

Although research on the reasons for engaging in nonsuicidal self-injury (NSSI) has increased dramatically in the last few years, there are still many aspects of this pernicious behavior that are not well understood. The purpose of this study was to address these gaps in the literature, with a particular focus on investigating whether NSSI (a) regulates affective valence in addition to affective arousal and (b) serves a cognitive regulation function in addition to an affect regulation function. To elucidate these issues, the present study utilized a sample of 112 participants (33 controls, 39 no pain controls, 16 NSSI individuals, and 24 controls matching the affect dysregulation levels of the NSSI group), employed psychophysiological measures of affective valence (startle-alone reactivity) and quality of information processing (prepulse inhibition), and used experimental methods involving an NSSI-proxy to model the NSSI process. Results largely were consistent with predictions, supporting the hypotheses that NSSI serves to regulate cognitive processing and affective valence. On this latter point, however, the control groups also showed a decrease in negative affective valence after the NSSI-proxy. This unexpected finding is consistent with the hypothesis that opponent processes may contribute to the development of self-injurious behaviors (Joiner, 2005). Overall, the present study represents an important extension of previous laboratory NSSI studies and provides a fertile foundation for future studies aimed at understanding why people engage in NSSI.     

Diagnosing Organizational Innovation: Measuring the Capacity for Innovation

Organizational innovation involves reconciling many contradictions or paradoxes. Dividing the process of innovation into phases ranging from Activation to Validation and examining each phase in terms of the six Ps of creativity offers a framework for making sense of these contradictions. The Innovation Phase Assessment Instrument (IPAI) was designed to assess organizations according to such an approach. The scale was administered to 454 student volunteers and an analysis of their responses indicated that the IPAI is highly reliable and has substantial construct validity. At a practical level, it can be used for assessing the strengths/weaknesses of organizations in a differentiated way and for making recommendations for improving their capacity for innovation. It is also a source of research questions for examining creativity and innovation in an organizational context.
