Understanding team adaptation: a conceptual analysis and model

This endeavor provides a multidisciplinary, multilevel, and multiphasic conceptualization of team adaptation with theoretical roots in the cognitive, human factors, and industrial-organizational psychology literature. Team adaptation and the emergent nature of adaptive team performance are defined from a multilevel, theoretical standpoint. An input-throughput-output model is advanced to illustrate a series of phases unfolding over time that constitute the core processes and emergent states underlying adaptive team performance and contributing to team adaptation. The cross-level mixed-determinants model highlights team adaptation in a nomological network of lawful relations. Testable propositions, practical implications, and directions for further research in this area are also advanced.     

The affective underpinnings of job perceptions and attitudes: a meta-analytic review and integration

Using psychometric meta-analysis, the authors present a quantitative and qualitative review (k = 205, total pairwise N = 62,527) of the literature relating trait and state positive affect (PA) and negative affect (NA) to job-related attitudes, including job satisfaction, organizational commitment, turnover intentions, and dimensions of job burnout. Results indicated substantial correlations, ranging in absolute value from -.17 (PA and turnover intentions; NA and personal accomplishment) to.54 (NA and emotional exhaustion). Correlational results largely were consistent across hypothesized and exploratory moderator conditions. Meta-analytic multiple regression results generally supported the unique contribution of each affect to each attitude variable of interest. Implications and suggestions for future research on emotion-related aspects of job attitudes are discussed.     

Tridimensional personality traits of college student marijuana users

The present study examined the possibility that marijuana use among college students might be associated with particular personality traits. College student volunteers (N = 176) were administered the Tridimensional Personality Questionnaire and a drug-use questionnaire. Analysis of variance showed that the mean score on Novelty Seeking was significantly higher and on Persistence significantly lower among lifetime marijuana users than among nonmarijuana using peers. Programs for prevention among college students may be enhanced by approaches tailored to individuals scoring high on Novelty Seeking and low on Persistence.     

Assessing the Experience of Autonomy in New Cultures and Contexts

This research demonstrates the usefulness of the technique of Smallest Space Analysis (SSA) in the construction of indices of the experience of autonomy, a central construct in Ryan and Deci’s self-determination theory of motivation and personality (SDT, 2000) and a construct central to recent controversies on socialization in different cultures. We propose that SSA has two advantages in comparison to correlation tables in the assessment of the experience of autonomy. First, it allows easy identification of items that best capture the various motivations along the relative autonomy continuum postulated by SDT. Second, and more important, it can reveal data patterns that might contribute to theoretical refinement that otherwise might remain unnoticed. These advantages were demonstrated in three Israeli samples: two samples of elementary school children (n = 697 and n = 417), and one sample of high school students (n = 317). Discussion considers ways in which SSA can contribute to the development and refinement of measures and theory pertaining to the experience of autonomy in cultures and contexts not examined so far.

Effect of action video games on the spatial distribution of visuospatial attention

The authors investigated the effect of action gaming on the spatial distribution of attention. The authors used the flanker compatibility effect to separately assess center and peripheral attentional resources in gamers versus nongamers. Gamers exhibited an enhancement in attentional resources compared with nongamers, not only in the periphery but also in central vision. The authors then used a target localization task to unambiguously establish that gaming enhances the spatial distribution of visual attention over a wide field of view. Gamers were more accurate than nongamers at all eccentricities tested, and the advantage held even when a concurrent center task was added, ruling out a trade-off between central and peripheral attention. By establishing the causal role of gaming through training studies, the authors demonstrate that action gaming enhances visuospatial attention throughout the visual field.     

Sooner versus later: factors associated with temporal sequencing of suicide

There are few (if any) population-based prospective studies that provide information on factors associated with temporal sequencing of suicide. In this prospective population-based study, the National Health Interview Survey (NHIS), 1986-1994, was linked to the National Death Index (NDI), 1986-1997, to assess factors that predict recent (within 12 months of interview, termed sooner) suicide versus suicide further in the future (more than 12 months after interview, termed later). Of the 653 completed suicides in the NHIS cohort, 13.4 percent completed suicide within a year of interview, and 86.6 percent did so after a year. Sooner decedents were more likely to be White, less educated, unemployed, and to use firearms than any other method compared with later decedents. Surprisingly, sooner decedents had higher levels of self-rated health at baseline. These results have substantial implications for clinicians and other professionals who interact with people at highest risk of suicide. Unfortunately, it may be unrealistic to expect that health care providers can modify the behavior of individuals at highest risk of suicide.     

The onset of receding motion captures attention: comment on Franconeri and Simons (2003)

Franconeri & Simons (2003) reported that some but not all types of motion capture attention in a visual search task, ostensibly because some types of motion are behaviorally significant. In the present article, we argue that a more parsimonious explanation of their results is that the onset of motion, but not motion per se, captures attention. This conclusion helps to resolve inconsistencies between the Franconeri and Simons findings and earlier reports from other investigators and is consistent with results that we have recently reported (Abrams & Christ, 2003). The Franconeri and Simons interpretation rests largely on their failure to find attentional capture by one type of motion-simulated receding motion. We report here the results of two experiments that demonstrate that the onset of receding motion does indeed capture attention when the motion is produced using stereo depth cues. As we have argued elsewhere, the capture of attention in displays containing motion appears to be dependent on the onset of the motion, rather than on the mere presence of specific types of motion as suggested by Franconeri and Simons. One possible explanation is that the onset of motion captures attention because it serves as a strong cue to animacy--and the detection of nearby animals can have important consequences for survival.
