Coming to terms: quantifying the benefits of linguistic coordination

Sharing a public language facilitates particularly efficient forms of joint perception and action by giving interlocutors refined tools for directing attention and aligning conceptual models and action. We hypothesized that interlocutors who flexibly align their linguistic practices and converge on a shared language will improve their cooperative performance on joint tasks. To test this prediction, we employed a novel experimental design, in which pairs of participants cooperated linguistically to solve a perceptual task. We found that dyad members generally showed a high propensity to adapt to each other's linguistic practices. However, although general linguistic alignment did not have a positive effect on performance, the alignment of particular task-relevant vocabularies strongly correlated with collective performance. In other words, the more dyad members selectively aligned linguistic tools fit for the task, the better they performed. Our work thus uncovers the interplay between social dynamics and sensitivity to task affordances in successful cooperation.     

Eye movements and the perceptual span in silent and oral reading

Previous research has examined parafoveal processing during silent reading, but little is known about the role of these processes in oral reading. Given that masking parafoveal information slows down silent reading, we asked whether a similar effect also occurs in oral reading. To investigate the role of parafoveal processing in silent and oral reading, we manipulated the parafoveal information available to readers by changing the size of a gaze-contingent moving window. Participants read silently and orally in a one-word window and a three-word window condition as we monitored their eye movements. The lack of parafoveal information slowed reading speed in both oral and silent reading. However, the effects of parafoveal information were larger in silent reading than in oral reading, because of different effects of preview information on both when the eyes move and how often. Parafoveal information benefitted silent reading for faster readers more than for slower readers.     

Salesperson Motivation to Perform and Job Satisfaction: A Sales Contest Participant Perspective

Salespeople's perceptions of a program of sales contests offered by several organizations over time are empirically assessed, and related to both sales performance and job satisfaction. The results suggest variability in attitudes toward contest benefits, goals, rewards, budget, themes, timing and frequency, and outcomes. Conclusions and managerial implications are discussed.

Suicide Exposure in the Population: Perceptions of Impact and Closeness

Recent studies of people exposed to suicide point to a continuum of effects moderated by a perception of closeness to the deceased. We investigated the importance of perception of impact of the death on mental health outcomes of those exposed to suicide. Female sex, younger age, and multiple exposures to suicide were associated with greater risk for poorer outcomes. Suicide exposed with high impact was more likely to have depression, anxiety, posttraumatic stress disorder, prolonged grief, and suicide ideation. Findings can help focus postvention resources for suicide‐exposed individuals.     

Relations between symptom severity,illness perceptions,visceral sensitivity,coping strategies and well-being in irritable bowel syndrome guided by the common sense model of illness

Irritable Bowel Syndrome (IBS) is a common condition affecting around 10–20% of the population and associated with poorer psychological well-being and quality of life. The aim of the current study was to explore the efficacy of the Common Sense Model (CSM) using Structural Equation Modelling (SEM) in an IBS cohort. One hundred and thirty-one IBS patients (29 males, 102 females, mean age 38 years) participating in the IBSclinic.org.au pre-intervention assessment were included. Measures included IBS severity (Irritable Bowel Syndrome Severity Scoring System), coping patterns (Carver Brief COPE), visceral sensitivity (Visceral Sensitivity Index), illness perceptions (Brief Illness Perceptions Questionnaire), psychological distress (Depression, Anxiety and Stress Scale), and quality of life (IBS Quality of Life scale; IBS-QoL). Using SEM, a final model with an excellent fit was identified (χ² (8) = 11.91, p = .16, χ²/N = 1.49, CFI > .98, TLI > .96, SRMR < .05). Consistent with the CSM, Illness perceptions were significantly and directly influenced by IBS severity (β = .90, p < .001). Illness perceptions in turn directly influenced maladaptive coping (β = .40, p < .001) and visceral sensitivity (β = .70, p < .001). Maladaptive coping and visceral sensitivity were significantly associated with psychological distress (β = .55, p < .001; β = .22, p < .01) and IBS-QoL (β = –.28, p < .001; β = –.62, p < .001). Based on these findings, we argue that to augment the adverse impact of IBS severity on IBS-QoL and psychological distress, psychological interventions will be best to target the mediating psychological processes including illness beliefs, visceral sensitivity and maladaptive coping.     

The Efficacy of the General Aptitude Test Battery in Allocating Prisoners to Work and Trade Training Courses

Ninety trainees at Deerbolt Borstal, County Durham, were randomly assigned to four groups for placement on trade training courses and work. The first group was assigned on the basis of the General Aptitude Test Battery and a brief interview about their interests; the second group on the basis of the General Aptitude Test Battery; the third group on the interview about their interests; whilst the fourth group was assigned randomly to existing vacancies. A 16-week follow-up showed significant differences across the groups in terms of successfully completing placements, the General Aptitude Test Battery being the crucial factor in allocating individuals successfully. Ratings of trainee performance from supervisors taken after two weeks did not, however, show significant differences across the groups.     

Observations on Long-Term Group Therapy with Suicidal and Depressed Persons

ABSTRACT: A long-term, open-ended group for depressed and suicidal individuals who had made suicide attempts is described. Two hundred persons participated in the sample groups over a 46-month period, with only 10 suicide attempts and 1 suicide occurring in this high risk group during the period of the study. Our observations corroborated some findings and differed with others reported of experiences with groups of individuals who have manifested suicidal behavior. The paper includes recommendations for starting groups of suicidal persons and emphasizes that this method of therapy appears to be an effective mode of suicide prevention.     

How obstructing is an obstacle? The influence of starting posture on obstacle avoidance

The introduction of non-target objects into a workspace leads to temporal and spatial adjustments of reaching trajectories towards a target. Currently, there are two different explanations for this phenomenon: the non-target objects are considered as either physical obstacles to which we maintain a preferred distance (see Tresilian, 1998) or as distractors that interfere with movement planning (see Tipper, Howard, & Jackson, 1997). These components are difficult to disentangle, however. Our aim was to determine the unique contribution of the avoidance of a physical obstacle to the adjustments of reaching trajectories. In this study, we manipulate the degree of physical obstruction by non-target objects while keeping the a priori visual layout of the workspace more or less constant. This is achieved by placing participants in different starting postures with respect to the orientation of their limb segments. Participants reach towards and grasp target objects with non-targets present in the workspace in a frontal and a lateral starting posture. In the frontal conditions participants showed larger movements away from the non-target on the ipsilateral side of the workspace than in the lateral conditions. The results provide evidence for the interpretation that non-targets influence the movement trajectory partly because they are 'obstructing'.
