The Creation of Ideals: A Question of the Energy-Distribution in the Personality Field

Semantic contrast occurs when Ss' ratings of the meaning of a word shift as a function of the context in which that word occurs. The current set of studies, using male and female undergraduates as Ss, was designed to determine the conditions necessary to produce semantic contrast. In Experiment 1 (N = 50), words referring to physical beauty and temperature were scaled and used to construct stimuli for subsequent experiments. In Experiment 2 (N = 72), contrast occurred with the temperature expressions with both a limited and extended response mode. However, no contrast effects occurred with either response mode for the expressions of beauty in Experiment 3 (N = 72). These findings suggest that the elaboration of information in semantic memory varies. To the extent that there is an elaborate representation, items will be resistant to contextual effects, while the meaning of less-elaborated items will be affected by the context in which they are experienced.     

Walker on the voluntariness of judgment 1

In his paper ‘The Voluntariness of Judgment’ Mark Thomas Walker claims that judgments are voluntary acts. According to Walker, theoretical reasoning can be seen as an instance of practical reasoning, and the outcomes of practical reasoning are actions. There are two reasons why Walker's argument does not establish this conclusion: (i) There are non‐reflective judgments which cannot reasonably be described as instances of practical reasoning; Walker's argument does not apply to these judgments, (ii) If one judges that p as a result of deliberation, one has had no choice sincerely to judge as well that non‐p instead of p, that is, one cannot judge contrary to one's evidence. Therefore, reflective judgments are not voluntary actions. Walker cannot show that reflective judgments are voluntary, because he fails to give a clear notion of a voluntary action and the role of choice.     

Extending the Validity of the Personality Assessment Inventory's (PAI) Level of Care Index (LOCI) in Multiple Psychiatric Settings

The purpose of this study was to extend the validity and clinical application of the Level of Care Index (LOCI) from the Personality Assessment Inventory (PAI) in 2 independent psychiatric samples. In Study 1 (N = 201), the LOCI effectively differentiated level of care (inpatients from outpatients), and was also meaningfully associated with risk factors for psychiatric admission (e.g., suicidal ideation, self-harming behavior, previous psychiatric admission, etc.), even after controlling for other demographic variables (range of Cohen's ds = 0.57–1.00). Likewise, the LOCI also incremented other risk indicators (suicide and violence history) and relevant PAI indexes (i.e., Mean Clinical Elevation, and Suicide and Violence Potential) in predicting level of care, and explained an additional 6% to 12% of variance in the target variable. Diagnostic efficiency analyses indicated LOCI scores in the range of 15 to 18 optimize positive and negative predictive power, and classification rate. In Study 2 (N = 96), the LOCI was found to be significantly higher in those with a recent psychiatric admission within the past 6 months (d = 0.64), as compared to those without an admission. Similarly, those who were admitted for suicide risk had significantly higher mean LOCI scores as compared to those who did not (d = 0.70). The clinical implications of these findings and potential application of the LOCI are discussed.     

Can we really reduce ethnic prejudice outside the lab? A meta‐analysis of direct and indirect contact interventions

The present meta‐analysis tested the effectiveness of contact‐based interventions for the reduction of ethnic prejudice. Up to now, a meta‐analysis summarizing the results of real‐world interventions that rest on the intergroup contact theory has been missing. We included evaluations of programs realizing direct (i.e., face‐to‐face) and/or indirect (i.e., extended or virtual) contact in real‐world settings outside the lab. The interventions' effectiveness was tested shortly after their end (k = 123 comparisons, N = 11 371 participants) and with a delay of at least 1 month (k = 25, N = 1650). Our data show that contact interventions improve ethnic attitudes. Importantly, changes persist over time. Furthermore, not only direct but also indirect contact interventions are successful. In addition, contact programs are effective even in the context of a serious societal conflict (e.g., in the Middle East). Although changes are typically larger for ethnic majorities, there is an impact on minorities, too. Finally, contact interventions not only improve attitudes toward individuals involved in the program, their effects also generalize to outgroups as a whole. In sum, social psychology provides an intervention for prejudice reduction that can be successfully implemented in the practical field. Copyright © 2015 John Wiley & Sons, Ltd.     

Independent priming of location and color in identification of briefly presented letters

Attention shifts are facilitated if the items to be attended remain the same across trials. Some researchers argue that this priming effect is perceptual, whereas others propose that priming is postperceptual, involving facilitated response selection. The experimental findings have not been consistent regarding the roles of variables such as task difficulty, response repetition, expectancies, and decision-making. Position priming, when repetition of a target position facilitates responses on a subsequent trial, is another source of disagreement among researchers. Experimental results have likewise been inconsistent as to whether position priming is dependent on the repetition of target features or has an independent effect on attention shifts. We attempted to isolate the perceptual components of priming by presenting brief (10–180 ms) search arrays to eight healthy observers. The task was to identify a color-singleton letter among distractors. All stimulus presentation contingencies were randomized, and responses were unspeeded, to avoid effects of observer expectation and postperceptual effects. Repeating target color and/or position strongly improved performance. The effects of color and position repetition were independent of one another and were stable across participants. The results argue for a strong perceptual component in priming, which biases selection toward recent target features and positions, showing that perceptual mechanisms are sufficient to produce priming in visual search and that such effects can be elicited with limited sensory evidence. The results are the first to demonstrate independent priming of color and position in the identification of briefly presented, postmasked stimuli.     

Association between brain activation (fMRI), cognition and school performance in extremely preterm and term born children

The purpose of the study was to investigate a possible association between brain activation in functional magnetic resonance imaging scans, cognition and school performance in extremely preterm children and term born controls. Twenty eight preterm and 28 term born children were scanned while performing a working memory/selective attention task, and school results from national standardized tests were collected. Brain activation maps reflected difference in cognitive skills but not in school performance. Differences in brain activation were found between children born preterm and at term, and between high and low performers in cognitive tests. However, the differences were located in different brain areas. The implication may be that lack of cognitive skills does not alone explain low performance due to prematurity.     

Culture and empowerment in the Deaf community: An analysis of internet weblogs

Although deafness is traditionally conceptualized as a medical problem or disability, about 500 000 deaf people in the United States identify as members of an ethno‐linguistic minority that takes pride in being Deaf. This study examined 416 Internet weblog posts authored by nine Deaf bloggers to describe aspects of Deaf culture and individual and community level empowerment strategies expressed in weblogs. Results highlight aspects of American Deaf culture, such as the value placed on American Sign Language and equal treatment of D/deaf and hearing people. Findings also provide evidence of expressions of Deaf culture such as the use of humour and supporting the community that have been less emphasized in previous literature. Community level empowerment strategies evident in posts included disseminating information, rallying the involvement of members and advocating for social justice. Overlap between expressions of Deaf culture and empowerment strategies were also found. Present results inform a growing literature on empowerment strategies that occur without intervention by professionals. Implications of the study for community research and action are discussed.

Episodic retrieval and feature facilitation in intertrial priming of visual search

Huang, Holcombe, and Pashler (Memory & Cognition, 32, 12-20, 2004) found that priming from repetition of different features of a target in a visual search task resulted in significant response time (RT) reductions when both target brightness and size were repeated. But when only one feature was repeated and the other changed, RTs were longer than when neither feature was repeated. From this, they argued that priming in visual search reflected episodic retrieval of memory traces, rather than facilitation of repeated features. We tested different variations of the search task introduced by Huang et al., with the aim of uncovering when priming is episodic and when feature based. We found that varying the signal strength of target against distractors had a strong effect on the priming pattern. In difficult search with low signal-to-noise ratios of target against distractors, the priming patterns were episodic. When feature contrasts between target and distractors were increased, priming of different features was independent and additive. Our results suggest that, during inefficient search,priming can be episodic but that, for more efficient search, priming from different features occurs independently. The results support two-stage (or multistage) accounts of priming in visual search.
