The Conceptualization of Team Flow

Despite the noted potential for team flow to enhance a team's effectiveness, productivity, performance, and capabilities, studies on the construct in the workplace context are scarce. Most research on flow at the group level has been focused on performance in athletics or the arts, and looks at the collective experience. But, the context of work has different parameters, which necessitate a look at individual and team level experiences. In this review, we extend current theories and essay a testable, multilevel model of team flow in the workplace that includes its likely prerequisites, characteristics, and benefits.

Tossing the baby with the (magnetized) bathwater: commentary on jacobson and colleagues

This article critiques two studies conducted by Jacobson and colleagues whose findings indicated that hypnosis hinders encoding and might not be useful in education. While their findings provide important information about hypnosis and its possible uses in teaching and learning, there are several important methodological and interpretive shortcomings that limit the applicability of the study. It is argued that the authors conflated some components of hypnotic phenomenology, as measured by the Phenomenology of Consciousness Inventory, and consequently failed to assess the hypnotic experience properly. This article argues that the encoding deficits produced by hypnosis may have resulted from the way hypnosis was used and other contextual factors, and highlights some additional concerns with the statistical analyses. This article suggests some more effective uses of hypnosis and suggestion in improving the learning process in light of prior research, and offers some ideas for future research.

Factors that contribute to the willingness to try "street hypnosis"

This study takes a context-specific approach to examine people's willingness to try hypnosis under various conditions and the factors that contribute to their willingness. It examined 378 participants, who completed a web-based hypnosis survey. The results showed that people's willingness to try hypnosis varies by context. Specifically, people are more willing to try hypnosis when it is framed as "peak focus" rather than "hypnosis" and when they perceive the environment as being safer. Moreover, factors including participants' demographics, hypnotists' demographics (relative to the subjects'), participants' control bias, and knowledge of hypnosis affect people's degrees of willingness to try hypnosis, depending on the specific context. The results suggest further analysis of hypnosis occurring in public contexts and the effects it may have on attitudes and therapeutic outcomes.

A proposed model for an optimal mentoring environment for medical residents: a literature review

PURPOSE

To develop a model of the optimal mentoring environment for medical residents. The authors propose that such an environment is a function of a relationship that rests upon a set of interactional foundations that allow a protégé to capitalize on the strengths of the mentor, and it facilitates behaviors that will enable the protégé to develop and internalize the requisite knowledge, skills, and attitudes (KSAs) as fully as possible.

METHOD

The authors searched the literature using Web of Science and Google Scholar in 2007-2008 to identify articles addressing the mentoring process and the context in which it occurs (mentoring environment), and the effect both have on KSA development. The authors distilled the attributes of a good mentor that were consistent across the 20 papers that met inclusion criteria and described good mentoring of residents or curricula for training mentors or residents.

RESULTS

The authors identified six interactional foundations that underlie the optimal mentoring relationship: emotional safety, support, protégé-centeredness, informality, responsiveness, and respect. These foundations enable protégés to engage in four key developmental behaviors: exercising independence, reflecting, extrapolating, and synthesizing.

CONCLUSIONS

This model identifies mentoring practices that empower protégés to engage in developmental behaviors that will help them become the best physicians possible. Educators may use this model to develop training tools to teach attendings how to create an optimal mentoring environment. Researchers can use the model to help guide their future investigations of mentoring in medicine.

Amygdala volume associated with alcohol abuse relapse and craving

OBJECTIVE

Amygdala volume has been associated with drug craving in cocaine addicts, and amygdala volume reduction is observed in some alcohol-dependent subjects. This study sought an association in alcohol-dependent subjects between volumes of reward-related brain regions, alcohol craving, and the risk of relapse.

METHOD

Besides alcohol craving, the authors assessed amygdala, hippocampus, and ventral striatum volumes in 51 alcohol-dependent subjects and 52 age- and education-matched healthy comparison subjects after detoxification. After imaging and clinical assessment, patients were followed for 6 months and alcohol intake was recorded.

RESULTS

Alcohol-dependent subjects showed reduced amygdala, hippocampus, and ventral striatum volumes and reported stronger craving in relation to healthy comparison subjects. However, only amygdala volume and craving differentiated between subsequent relapsers and abstainers. A significant decrease of amygdala volume in alcohol-dependent subjects was associated with increased alcohol craving before imaging and an increased alcohol intake during the 6-month follow-up period.

CONCLUSIONS

These findings suggest a relationship between amygdala volume reduction, alcohol craving, and prospective relapse into alcohol consumption.

Heart-rate variability as a quantitative measure of hypnotic depth

The authors investigated whether heart-rate variability can serve as a device for real-time quantitative measurement of hypnotic depth. This study compared the continuous self-rated hypnotic depth (SRHD) of 10 volunteers with heart rate, amplitude, and frequency changes from a time-frequency analysis of heart-rate variability (HRV). The authors found significant linear relationships between SRHD and the high-frequency (HF) component of HRV. Specifically, SRHD was correlated negatively with the frequency of the HF component and positively with the amplitude of the HF component. Unexpectedly, the average temporal trend in SRHD fit well (R(2) = .99) to the step response of a first-order system with a 4-minute time constant. The findings suggest that the reactivity of the parasympathetic branch of the autonomic nervous system reflected in HRV could become part of a real-time, quantitative measure of hypnotic depth.
