Perceptual latency priming by masked and unmasked stimuli: evidence for an attentional interpretation

Four experiments investigated the influence of a metacontrast-masked prime on temporal order judgments. The main results were (1) that a masked prime reduced the latency of the mask's conscious perception (perceptual latency priming), (2) that this effect was independent of whether the prime suffered strong or weak masking, (3) that it was unaffected by the degree of visual similarity between the prime and the mask, and that (4) there was no difference between congruent and incongruent primes. Finding (1) suggests that location cueing affects not only response times but also the latency of conscious perception. (2) The finding that priming was unaffected by the prime's detectability argues against a response bias interpretation of this effect. (3) Since visual similarity had no effect on the prime's efficiency, it is unlikely that sensory priming was involved. (4) The lack of a divergence between the effects of congruent and incongruent primes implies a functional difference between the judgments in the temporal order judgment task and speeded responses that have demonstrated differential effects of congruent and incongruent primes (e.g., Klotz & Neumann, 1999). These results can best be interpreted by assuming that the prime affects perceptual latency by initiating a shift of attention, as suggested by the Asynchronous Updating Model (AUM; Neumann 1978, 1982).     

More efficient rejection of happy than of angry face distractors in visual search

In the present study, we examined whether the detection advantage for negative-face targets in crowds of positive-face distractors over positive-face targets in crowds of negative faces can be explained by differentially efficient distractor rejection. Search Condition A demonstrated more efficient distractor rejection with negative-face targets in positive-face crowds than vice versa. Search Condition B showed that target identity alone is not sufficient to account for this effect, because there was no difference in processing efficiency for positive- and negative-face targets within neutral crowds. Search Condition C showed differentially efficient processing with neutral-face targets among positive- or negative-face distractors. These results were obtained with both a within-participants (Experiment 1) and a between-participants (Experiment 2) design. The pattern of results is consistent with the assumption that efficient rejection of positive (more homogenous) distractors is an important determinant of performance in search among (face) distractors.     

Bayesian decision theory in sensorimotor control

Action selection is a fundamental decision process for us, and depends on the state of both our body and the environment. Because signals in our sensory and motor systems are corrupted by variability or noise, the nervous system needs to estimate these states. To select an optimal action these state estimates need to be combined with knowledge of the potential costs or rewards of different action outcomes. We review recent studies that have investigated the mechanisms used by the nervous system to solve such estimation and decision problems, which show that human behaviour is close to that predicted by Bayesian Decision Theory. This theory defines optimal behaviour in a world characterized by uncertainty, and provides a coherent way of describing sensorimotor processes.     

Facial attractiveness is appraised in a glance

Those who are physically attractive reap many benefits--from higher average wages to a wider variety of mate choices. Recent studies have investigated what constitutes beauty and how beauty affects explicit social judgments, but little is known about the perceptual or cognitive processing that is affected by aesthetic judgments of faces and why beauty affects our behavior. In this study, the authors show that beauty is perceived when information is minimized by masking or rapid presentation. Perceiving and processing beauty appear to require little attention and to bias subsequent cognitive processes. These facts may make beauty difficult to ignore, possibly leading to its importance in social evaluations.     

Team Climate Inventory with a merged organization

The present study examines the team climate for innovation in work teams within a newly merged organization. Four teams working at a regional head office of a Social Insurance organization answered the Team Climate Inventory. The results were compared to those of a study by Agrell and Gustafson of more stable teams. The comparison showed that participative safety and support for innovation were rated lower and that vision was rated higher in the newly merged teams. The 38-item original inventory was used and based on the results, a 1999 proposed shortened version of 14 items by Kivim?ki and Elovainio was compared with the original one. Analysis indicated that the short version can be a valid alternative to the original version but that further testing of the short version is needed.     

Religion,Inclusive Individualism,and Volunteering in Europe

A well supported finding in social science is that religiosity is associated with pro-social behaviours such as volunteering, but the religious decline in Europe characterising the latter part of the twentieth century has not been accompanied by decline in voluntary participation. This period is also associated with a sharp increase in the moral emphasis on individual autonomy and inclusiveness over social norms and traditions. In this analysis of the European Values Study (2008–2010), I examine the relationship between religion and volunteering, taking both individual values and aggregate norms into account. Religious attendance is found to be associated with volunteering at the individual level. However, the average citizen’s likelihood of volunteering is lower in more religious countries. This could be due in part to secular countries’ high levels of inclusive individualism (autonomy values and generalised trust) which are positively associated with volunteering among both religious and non-religious respondents.     

A Comparison of Paper and Computer Administered Strengths and Difficulties Questionnaire

The Strengths and Difficulties Questionnaire (SDQ) is one of the most widely used measures of young people’s mental health difficulties in research and clinical decision-making. Although the SDQ is available in both paper and computer survey formats, cross-format equivalences have yet to be established. The current study aimed to assess the measure’s equivalence across paper- and computer-based survey formats in a community-based school setting. The study examined self-reported measures completed by a matched sample of 11–14 year olds in secondary schools in England (589 completed paper version; 589 online version). Analyses demonstrate that the factor structure, although did not vary by survey format, resulted in poorly fitting models limiting the use of model based invariance testing. Results indicate that the measure does not operate similarly across different formats, with scale-level mean differences observed for the hyperactivity scale, which also affects the total difficulties score, with higher scores seen in the paper version. Responses to the impact supplement were also influenced by survey format, with higher impact in specific domains disclosed on the computer-based measure. Item-level differential item functioning was observed for four items in the measure; two from the prosocial scale where the DIF is large enough to affect the scale (DTF, ν² = 0.14). The inconsistency across survey formats highlights the need for more assessment of influences of different survey formats on young people, their perceived privacy and their mental health disclosures via different media. The findings also highlight the potential confounding effect of format when different methods of data collection are used, with a potentially substantive impact on cross-sample comparisons and within child clinical review.     

Knowledge is power: How conceptual knowledge transforms visual cognition

In this review, we synthesize the existing literature demonstrating the dynamic interplay between conceptual knowledge and visual perceptual processing. We consider two theoretical frameworks that demonstrate interactions between processes and brain areas traditionally considered perceptual or conceptual. Specifically, we discuss categorical perception, in which visual objects are represented according to category membership, and highlight studies showing that category knowledge can penetrate early stages of visual analysis. We next discuss the embodied account of conceptual knowledge, which holds that concepts are instantiated in the same neural regions required for specific types of perception and action, and discuss the limitations of this framework. We additionally consider studies showing that gaining abstract semantic knowledge about objects and faces leads to behavioral and electrophysiological changes that are indicative of more efficient stimulus processing. Finally, we consider the role that perceiver goals and motivation may play in shaping the interaction between conceptual and perceptual processing. We hope to demonstrate how pervasive such interactions between motivation, conceptual knowledge, and perceptual processing are in our understanding of the visual environment, and to demonstrate the need for future research aimed at understanding how such interactions arise in the brain.     

Work Experiences of Foreign‐Born Asian Women Counseling and Psychology Faculty

Eleven foreign‐born and ‐raised Asian women faculty in counseling and psychology programs in the United States were interviewed about their work experiences. Analysis using consensual qualitative research revealed 7 sources of stressors, 6 emotional reactions associated with stressors, 5 coping strategies, and 4 types of intrinsic rewards gained from encountering challenges. The results of the study provide information about the unique experiences of this understudied group and have implications for the U.S. higher education system.
