Interocular suppression in normal and amblyopic subjects: The effect of unilateral attenuation with neutral density filters

In normal subjects, binocular rivalry suppression takes time to build up (Wolfe, 1986a). The time courses of interocular suppression are different and heterogeneous in amblyopic subjects (de Belsunce & Sireteanu, 1991). In the present study, we found that, in normal observers, progressive reduction of one eye’s stimulus luminance with neutral density filters produces time courses similar to those of amblyopic subjects. Conversely, in amblyopes, attenuation of the dominant eye’s stimulus produces time courses similar to those of normal observers. Under conditions of balancing of the two eyes, amblyopes experience alternating suppression, similarly to binocular rivalry of normals.     

Interactive effects of social network centrality and social identification on stress

The present study aimed to integrate the social identity approach to health and well-being with social network analysis. Previous research on the effects of social network centrality on stress has yielded mixed results. Building on the social identity approach, we argued that these mixed results can be explained, in part, by taking into account the degree to which individuals identify with the social network. We hence hypothesized that the effects of social network centrality on stress are moderated by social identification. Using a full roster method, we assessed the social network of first-year psychology students right after the start of their study programme and three months later. The effects of network centrality (betweenness, closeness, eigenvector centrality) and social identification on stress were examined using structural equation models. As predicted, our results revealed a significant interaction between network centrality and social identification on stress: For weakly or moderately identified students, network centrality was positively related to stress. By contrast, for strongly identified students, network centrality was unrelated to stress. In conclusion, our results point to the perils of being well-connected yet not feeling like one belongs to a group.     

Assessing Facets of Mindfulness in the Context of Work: The Mindfulness@Work Scale as a Work-Specific,Multidimensional Measure of Mindfulness

The mindfulness at work literature lacks a multi-faceted measure of mindfulness that is applicable in the work context. Building on predominantly clinically oriented, multi-faceted mindfulness measures, we aimed to develop and validate such a measure and to provide first insights into differential validities of mindfulness subfacets for work outcomes. Data from seven work samples (overall n = 4,977) provided support that (a) a 4-factor structure representing the subfacets of Describing, Nonreactivity, Nonjudging, and Act with Awareness replicates across samples; (b) subfacets and overall scale have good internal consistency and retest reliability; (c) the measure demonstrates convergent and discriminant validity; (d) it demonstrates criterion-related validity for well-being, motivational, and interpersonal work outcomes; (e) the Mindfulness@Work Scale explains variance in outcome variables above a unidimensional measures of mindfulness supporting its incremental validity. Furthermore, relative weights and incremental validity analyses revealed differential validities of subfacets of the Mindfulness@Work Scale in relation to positive psychological states versus psychological distress. Overall, findings suggest that the Mindfulness@Work Scale has good psychometric properties and that a differentiation of subfacets provides novel insights into the role of mindfulness for work outcomes.     

Aging and conditional probability judgments: a global matching approach

Age differences in bias in conditional probability judgments were investigated based on predictions derived from the Minerva-Decision Making model (M. R. P. Dougherty, C. F. Gettys, & E. E. Ogden, 1999), a global matching model of likelihood judgment. In this study, 248 younger and older adults completed frequency judgment and conditional probability judgment tasks. Age differences in the frequency judgment task are interpreted as an age-related deficit in memory encoding. Older adults' stronger biases in the probability judgment task point to age differences in criterion setting. Age-related biases were eliminated when age groups were equated on memory encoding by means of study time manipulation. The authors conclude that older adults' stronger judgment biases are a function of memory impairment.     

Prospective memory in young and older adults: the effects of ongoing-task load

Prospective memory involves remembering to perform intended actions in the future. Previous work with the multinomial model of event-based prospective memory indicated that adult age-related differences in prospective-memory performance were due to the prospective (not the retrospective) component of the task (Smith & Bayen, 2006 , Journal of Experimental Psychology: Learning, Memory, and Cognition, 32, 623). However, ongoing-task performance was also lower in older adults in that study. In the current study with young and older adults, the difficulty of the ongoing task was manipulated by varying the number of colors per trial to create easier and harder versions of the ongoing task for each age group. The easier version included 2 colors per trial for older adults and 4 colors for young adults. The harder version included 4 colors for older adults and 6 colors for young adults. By adjusting the ongoing-task difficulty, older adults were able to perform the ongoing task as well or better than the young adults. Analyses with the multinomial model revealed that making the ongoing task easier for older adults (or more difficult for young adults) did not eliminate age-related differences in prospective-memory performance and the underlying prospective component.     

Committing to implementation intentions: Attention and memory effects for selected situational cues

Two studies tested whether forming implementation intentions (Gollwitzer, Am Psychol 54:493?C503 in 1999) results in a heightened activation of specified situational cues. Going beyond prior studies, participants of the present studies specified these opportunities on their own (i.e., the action cues were not assigned by the experimenter), and activation level was assessed by attraction of attention and recall performance rather than lexical decisions. In Study 1, situational cues associated with the where and when to act on an everyday life goal attracted more attention than non-specified cues when presented to the non-attended channel in a dichotic listening task. In Study 2, the recall of specified cues was better than that of non-specified cues both 15?min after forming implementation intentions and after a delay of 2?days. Importantly, goal commitment and implementation intention commitment moderated this effect.
