DETERMINANTS OF R AND D COMPENSATION STRATEGIES IN THE HIGH TECH INDUSTRY

This study indicates that sales volume, stage in the product life cycle, profitability and turnover are all important predictors of the method and magnitude of financial rewards provided by high tech firms to R and D employees. The most favorable situational factors for R and D incentive compensation are a low sales volume high tech company, operating in the growth stage of the product life cycle, with high turnover rates, and capable of linking profitability to incentive rewards such as bonuses.     

Reduced looming sensitivity in primary school children with Developmental Co-ordination Disorder

Almost all locomotor animals are sensitive to optical expansion (visual looming) and for most animals this sensitivity is evident very early in their development. In humans there is evidence that responses to looming stimuli begin in the first 6 weeks of life, but here we demonstrate that as children become independent their perceptual acuity needs to be 50 to 100 times better than has been demonstrated in infants in order to be skilful at collision avoidance at a roadside. We have recently established that sensitivity to the detection of visual looming in 6- to 11-year-old children is significantly below that of adults (Wann, Poulter & Purcell, 2011). Here, using comparable methods, we explore looming detection sensitivity in children with Developmental Co-ordination Disorder (DCD), who show broad patterns of impairment in visuo-motor control. We presented visual simulations of approaching vehicles, scaled to represent different approach rates, to children with DCD aged between 6 and 11 years (n = 11) and typically developing age and gender matched controls (n = 11). Looming detection thresholds were measured under foveal and perifoveal viewing conditions, for isotropic expansion and isotropic expansion with simulated viewpoint motion. Our results show that there are situations in which children with DCD may fail to detect vehicles approaching at speeds in excess of 22 km/h, suggesting a developmental immaturity in looming sensitivity. This provides one of the first clear demonstrations of low-level motion processing deficits in children with DCD. The decrement observed may give rise to potential errors in the road crossing behaviour of these children, whereby approaching vehicles could be perceived as stationary. These findings further contribute towards understanding the adverse statistic that children under 9 years of age are four times more likely than adults to be involved in a road accident as a pedestrian.     

Toward a Better Understanding of Psychological Well‐Being in Dementia Caregivers: The Link Between Marital Communication and Depression

To read this article's abstract in both Spanish and Mandarin Chinese, please visit the article's full‐text page on Wiley InterScience ( http://interscience.wiley.com/journal/famp ). Dementia research has frequently documented high rates of caregiver depression and distress in spouses providing care for a partner suffering from dementia. However, the role of marital communication in understanding caregiver distress has not been examined sufficiently. Studies with healthy couples demonstrated an association between marital communication and the partners' psychological well‐being, depressiveness, respectively (e.g., Heene, Buysee, & Van Oost, 2005 ). The current study investigates the relationship between caregiver depression and communication in 37 couples in which the wives care for their partners with dementia. Nonsequential and sequential analyses revealed significant correlations between caregiver depression and marital communication quality. Caregivers whose husbands used more positive communication reported less depression and distress. Additionally, caregiver depression was negatively correlated with rates of positive reciprocal communication indicating dependence between the couples' interaction patterns. This study is one of the first to illustrate the relevance of spousal communication in understanding caregiver distress and depression.     

The Effect of Disguise on Novice and Expert Tennis Players’ Anticipation Ability

Skilled performers interpret cues in the preparatory movements of their opponents to anticipate future events in many sports. Little work has tested whether these cues can be disguised. Using a temporal occlusion paradigm, this paper examines the effect of disguise on an Australian sample of expert (16 male, 2 female, age M = 24.67, SD = 9.47 years) and novice players’ (24 male, 38 female, age M = 22.26, SD = 5.24 years) anticipation of tennis ground strokes. Analysis of variance (ANOVA) showed that expert anticipation was more accurate than novice overall (p < .001), and disguise reduced accuracy (p = .001). The disguise effect differed by expertise across occlusion points (p = .027). The experts’ anticipatory advantage was removed by disguise at 40 ms before contact. Novice performance was significantly below chance for disguise shots occluded at contact. These results indicate that disguise is an important topic for research and practice.
