Spatial asymmetries are an intriguing feature of directed attention. Recent observations indicate an influence of temperament upon the direction of these asymmetries. It is unknown whether this influence generalises to visual orienting behaviour. The aim of the current study was therefore to explore the relationship between temperament and measures of spatial orienting as a function of target hemifield. An exogenous cueing task was administered to 92 healthy participants. Temperament was assessed using Carver and White's (1994) Behavioural Inhibition System and Behavioural Activation System (BIS/BAS) scales. Individuals with high sensitivity to punishment and low sensitivity to reward showed a leftward asymmetry of directed attention when there was no informative spatial cue provided. This asymmetry was not present when targets were preceded by spatial cues that were either valid or invalid. The findings support the notion that individual variations in temperament influence spatial asymmetries in visual orienting, but only when lateral targets are preceded by a non-directional (neutral) cue. The results are discussed in terms of hemispheric asymmetries and dopamine activity. 相似文献

Globally, promoting mental wellbeing among adolescents is of great public health and social significance. However, less is known about advances in measures of mental wellbeing, relevant for use in mental health interventions, which are age-appropriate and acceptable for use among adolescents. Comprehensive assessment includes multiple aspects of mental wellbeing, as well as positive indicators of feeling and functioning. This review used systematic review methods, guided by PRISMA, to identify and assess comprehensive instruments in terms of their content, conceptual relevance for youth, and responsiveness to change. Ryan and Deci’s framework for mental wellbeing, grounded in hedonic and eudaimonic perspectives, was applied to assess the preponderance of feeling and functioning items for each instrument. The review identified 11 instruments that fit specified inclusion criteria. Only four of the scales were developed for adolescents. Though the scales varied in their preponderance of items, all scales encompassed at least one indicator of both feeling and functioning. Findings emphasize the importance of validating adult-developed instruments for youth and ensuring the instrument’s cultural and conceptual relevance within groups of adolescents. As promoting mental wellbeing becomes critical to the field of practice, practitioners need access to relevant and acceptable measures. 相似文献

The construct of perfectionistic cognitions is defined as a state-like construct resulting from a perfectionistic self-schema and activated by specific situational demands. Only a few studies have investigated whether and how perfectionistic cognitions change across different situations and whether they reflect stable between-person differences or also within-person variations over time. We conducted 2 studies to investigate the variability and stability of 3 dimensions of perfectionistic cognitions while situational demands changed (Study 1) and on a daily level during a highly demanding period of time (Study 2). The results of both studies revealed that stable between-person differences accounted for the largest proportion of variance in the dimensions of perfectionistic cognitions and that these differences were validly associated with between-person differences in affect. The frequency of perfectionistic cognitions increased during students' first semester at university, and these average within-person changes were different for the 3 dimensions of perfectionistic cognitions (Study 1). In addition, there were between-person differences in the within-person changes that were validly associated with concurrent changes in closely related constructs (unpleasant mood and tense arousal). Within-person variations in perfectionistic cognitions were also validly associated with variations in unpleasant mood and tense arousal from day to day (Study 2). 相似文献

We report a fascinating phenomenon that emerges when a surface is viewed through a tube held close to one eye, with the other eye open. The disk-shaped area seen through the tube looks strikingly brighter and, when viewed on a textured background, also of higher spatial contrast than the same surface area viewed without a tube. The effect is reminiscent of a spotlight illuminating the area under consideration. We call this the 'tube effect'. The tube effect is one of the strongest contrast illusions known to us. It requires a matching luminance that is twice as high as the reference luminance seen through the tube. Brightness ratings increase linearly with the log of the background luminance. The effect (i) produces a dark afterimage, (ii) reverses in polarity with low ambient illumination, (iii) assumes the complementary colour of the illuminant, and (iv) persists with fully dilated pupils. Potential explanations include simultaneous contrast (due to the penumbra and dark inner walls of the tube) and veiling of the surround (due to local adaptation and a lower gain factor). 相似文献

Research data should be made readily available. A robust data-sharing plan, led by the principal investigator of the research
project, requires considerable administrative and operational resources. Because external support for data sharing is minimal,
principal investigators should consider engaging existing institutional information experts, such as librarians and information
systems personnel, to participate in data-sharing efforts. 相似文献

This study compared marital satisfaction among three age groups and examined how negative interaction patterns and religiosity relate to marital satisfaction at each age using a sample of Protestants (N = 45,387) diverse in denominations, location, geography, and size. We performed a 1-way ANOVA to compare marital satisfaction among three age groups (younger than 40, 40–59, and 60 and older) and found a U-shape curve with marital satisfaction highest among the youngest group, lowest among middle-age couples, and high among older couples. ANCOVA analysis found negative interaction, age, religiosity, age*negative interaction, and age*religiosity to be predictors of marital satisfaction. 相似文献

Affordances have recently been proposed as a guiding principle in perception–action research in sport (Fajen, Riley, & Turvey, 2009). In the present study, perception of the ’passability’ affordance of a gap between two approaching defenders in rugby is explored. A simplified rugby gap closure scenario was created using immersive, interactive virtual reality technology where 14 novice participants (attacker) judged the passability of the gap between two virtual defenders via a perceptual judgment (button press) task. The scenario was modeled according to tau theory (Lee, 1976) and a psychophysical function was fitted to the response data. Results revealed that a tau-based informational quantity could account for 82% of the variance in the data. Findings suggest that the passability affordance in this case, is defined by this variable and participants were able to use it in order to inform prospective judgments as to passability. These findings contribute to our understanding of affordances and how they may be defined in this particular sporting scenario; however, some limitations regarding methodology, such as decoupling perception and action are also acknowledged. 相似文献
