Visible embodiment: Gestures as simulated action

Spontaneous gestures that accompany speech are related to both verbal and spatial processes. We argue that gestures emerge from perceptual and motor simulations that underlie embodied language and mental imagery. We first review current thinking about embodied cognition, embodied language, and embodied mental imagery. We then provide evidence that gestures stem from spatial representations and mental images. We then propose the gestures-as-simulated-action framework to explain how gestures might arise from an embodied cognitive system. Finally, we compare this framework with other current models of gesture production, and we briefly outline predictions that derive from the framework.     

Development and factor analysis of the Coaching and Athletic Training Questionnaire

To explore athletes' perceptions related to coaching and athletic training care, the Coaching and Athletic Training Questionnaire was developed. A 10-item version was administered to 708 varsity athletes from three Division I universities in the National Collegiate Athletic Association. 341 women and 344 men completed questionnaires. Data from half of the sample of 685 were used for an exploratory factor analysis using principal components analysis with oblique rotation and the second half for a confirmatory factor analysis. Analyses yielded three interpretable factors, accounting for 68% of the variance, which were labeled Comfort with Athletic Trainer or Coach, Sex Influence on Quality of Care, and Athletic Trainer Preference. Multivariate analysis of variance indicated that factor scores of women and men differed significantly, and at followup women and men differed significantly on Comfort with Athletic Trainer or Coach, but the small effect size minimizes its meaningfulness. No significant difference was noted for the other two factors. It appears coaches should be sensitive and available in case of injury or other need. Athletes' perceived quality of care by athletic trainers does not appear related to sex of athlete or trainer.     

Moving Beyond Self‐Report: Implicit Associations about Death/Life Prospectively Predict Suicidal Behavior among Veterans

Reliance on self‐report limits clinicians' ability to accurately predict suicidal behavior. In this study the predictive validity of an objective measure, the death/suicide Implicit Association Test (d/sIAT), was tested among psychiatrically hospitalized veterans. Following acute stabilization, 176 participants completed the d/sIAT and traditional suicide risk assessments. Participants had similar d/sIAT scores regardless of whether they had recently attempted suicide. However, d/sIAT scores significantly predicted suicide attempts during the 6‐month follow‐up above and beyond other known risk factors for suicidal behavior (OR = 1.89; 95% CI: 1.15–3.12; based on 1SD increase). The d/sIAT may augment the accuracy of suicide risk assessment.     

Learning From Gesture and Action: An Investigation of Memory for Where Objects Went and How They Got There

Speakers often use gesture to demonstrate how to perform actions—for example, they might show how to open the top of a jar by making a twisting motion above the jar. Yet it is unclear whether listeners learn as much from seeing such gestures as they learn from seeing actions that physically change the position of objects (i.e., actually opening the jar). Here, we examined participants' implicit and explicit understanding about a series of movements that demonstrated how to move a set of objects. The movements were either shown with actions that physically relocated each object or with gestures that represented the relocation without touching the objects. Further, the end location that was indicated for each object covaried with whether the object was grasped with one or two hands. We found that memory for the end location of each object was better after seeing the physical relocation of the objects, that is, after seeing action, than after seeing gesture, regardless of whether speech was absent (Experiment 1) or present (Experiment 2). However, gesture and action built similar implicit understanding of how a particular handgrasp corresponded with a particular end location. Although gestures miss the benefit of showing the end state of objects that have been acted upon, the data show that gestures are as good as action in building knowledge of how to perform an action.     

Veteran Participation in Intensive Suicide Research Protocols: No Evidence of Iatrogenic Effects

Suicide research remains fraught with ethical and methodological issues, including researchers’ reservations about conducting intensive suicide research protocols due to potential iatrogenic effects and liability concerns. Such issues significantly impede scientific inquiry related to suicide. To date, no research has explored potential iatrogenic effects of intensive, nontreatment suicide research among Veterans. This study aimed to fill this gap. It was hypothesized that participation in suicide‐specific protocols would not significantly increase risk among Veterans. Veterans completed self‐reports, structured interviews, and rigorous suicide‐specific tasks (Study A, N = 34; Study B, N = 18; Study C, N = 119). Findings indicated there were no significant differences in pre‐ and postassessment suicide risk variables (all ps > .05). Estimated mean change for “urge to harm self” was ?0.24 (95% confidence interval [CI]: ?0.60, 0.13), ?0.28 (CI: ?0.56, 0.01), and ?0.01 (CI: ?0.09, 0.07) and “intent to harm self” was ?0.18 (95% CI: ?0.45, 0.10), 0 (CI: ?0.17, 0.17), and 0.01 (CI: ?0.04, 0.06) for Studies A, B, and C, respectively. Results indicated the respective protocols did not produce iatrogenic effects. The current findings are discussed with attention to safety‐monitoring techniques that may reduce iatrogenic effects and considerations for future researchers.
