Beyond fear: rapid spatial orienting toward positive emotional stimuli

There is much empirical evidence for modulation of attention by negative -- particularly fear-relevant -- emotional stimuli. This modulation is often explained in terms of a fear module. Appraisal theories of emotion posit a more general mechanism, predicting attention capture by stimuli that are relevant for the needs and goals of the organism, regardless of valence. To examine the brain-activation patterns underlying attentional modulation, we recorded event-related potentials from 20 subjects performing a dot-probe task in which the cues were fear-inducing and nurturance-inducing stimuli (i.e., anger faces and baby faces). Highly similar validity modulation was found for the P1 time-locked to target onset, indicating early attentional capture by both positive and negative emotional stimuli. Topographic segmentation analysis and source localization indicate that the same amplification process is involved whether attention orienting is triggered by negative, fear-relevant stimuli or positive, nurturance-relevant stimuli. These results confirm that biological relevance, and not exclusively fear, produces an automatic spatial orienting toward the location of a stimulus.     

Trait expectancies and stereotype expectancies have the same effect on person memory

Two studies examined whether trait expectancies and stereotype expectancies similarly affected memory for expectancy-relevant behaviors. The results of both studies showed that, when activated in identical ways, trait expectancies and stereotype expectancies had similar effects on recall. Better recall was obtained for expectancy-incongruent items when expectancies were activated in relatively overt ways, while better recall for expectancy-congruent items was obtained when expectancies were activated in less overt ways. Additional analyses examining the order of events that emerged in the recall protocols provided little evidence that participants attempted to reconcile the items, as would be predicted by some earlier models of person memory (e.g., Srull, 1981). The implications of these findings for how social expectancies guide social information processing are discussed.     

Risk it? Direct and collateral impacts of peers' verbal expressions about hazard likelihoods*

When people encounter potential hazards, their expectations and behaviours can be shaped by a variety of factors including other people's expressions of verbal likelihood (e.g., unlikely to harm). What is the impact of such expressions when a person also has numeric likelihood estimates from the same source(s)? Two studies used a new task involving an abstract virtual environment in which people learned about and reacted to novel hazards. Verbal expressions attributed to peers influenced participants’ behaviour toward hazards even when numeric estimates were also available. Namely, verbal expressions suggesting that the likelihood of harm from a hazard is low (vs. higher) yielded more risk taking with respect to said hazard. There were also inverse collateral effects, whereby participants’ behaviour and estimates regarding another hazard in the same context were affected in the opposite direction. These effects may be based on directionality and relativity cues inferred from verbal likelihood expressions.     

Postural control in otolith disorders

It was the aim of the present paper to investigate the influence of otolith disorders on human postural control by different methods. The 33 patients of our study had undergone a minor head injury and suffered subsequently from an utricular or sacculo-utricular disorder as evidenced by vestibular evoked myogenic potential recordings and eccentric rotation recordings of the otolith-ocular responses. Postural control was assessed by performing stance/gait tests (standard balance deficit test, SBDT) and by evaluating trunk sway (using angular velocity sensors). Moreover, classical tests of the posterior column of the spinal tract (Romberg/Unterberger) and the dynamic posturography (sensory organization test, SOT) were included. It could be shown that SBDT tasks with reduced proprioceptive and visual cues (e.g. standing on foam, eyes closed) are most sensitive for an otolith disorder. The patients showed an increased trunk sway in the pitch plane (i.e. linear motion as adequate utricular stimulus) and an increase in sway velocities (i.e. tilting movements as adequate saccular stimulus) compared to controls. The SOT was most sensitive for combined (sacculo-utricular) otolith disorders (78%) while vestibulospinal tests are not enough sensitive. In essence, otolith disorders evidently impair human postural control and have been possibly underestimated as a source of posttraumatic postural imbalance as yet.     

A comparison of coping factors in Western and non-Western cultures

This study presents convergent support for the use of three empirically constructed factors, across four samples, from the Ways of Coping Questionnaire. Planning, Positive Reappraisal, and Distancing factors were congruent for comparisons made between U.S. healthcare workers, Chinese healthcare workers, Chinese teachers, and Taiwanese teachers. Additional evidence of congruency was provided on specific factors between specific pairs of groups. The results support the usage of common factors across languages, cultures, and occupational groups but also highlight the importance of not administering a test in a different cultural setting without assessing its dimensionality.     

The effects of gender role orientation on team schema: a multivariate analysis of indicators in a US Federal health care organization

In this empirical study of 649 employees at a federally supported health care facility in the United States, the authors investigated the effects of individual gender role orientation on team schema. The results indicated (a) that nontraditional male and female employees perceived the greatest amount of group cohesion in their team schemas and (b) that both traditional and nontraditional male employees perceived greater problem-solving potential in their team schemas. Meaningful implications for team composition are discussed.     

Self–other differences in multiattribute decision making: Compensatory versus noncompensatory decision strategies

When making decisions where options involve multiple attributes, a person can choose to use a compensatory, utility maximizing strategy, which involves consideration and integration of all available attributes. Alternatively, a person can choose a noncompensatory strategy that extracts only the most important and reliable attributes. The present research examined whether other‐oriented decisions would involve greater reliance on a noncompensatory, lexicographic decision strategy than self‐oriented decisions. In three studies (Mturk workers and college students), the difference in other‐oriented versus self‐oriented decisions in a medical decision context was explained by a subsample of participants that chose the death minimizing operation on all 10 decisions (Study 1) and a subsample of participants who self‐reported that they used a strategy that minimized the chance of death on every decision (i.e., a lexicographic mortality heuristic; Study 2). In Study 2, tests of mediation found that self‐reported use of the mortality heuristic completely accounted for the self–other effect on decisions. In Study 3, participants were more likely to report prospectively that they would adopt the mortality heuristic when making decisions for others than for themselves, suggesting that participants were not mistakenly inferring a lexicographic decision strategy from their past behavior. The results suggest that self–other effects in multiattribute choice involve differential use of compensatory versus noncompensatory decision strategies and that beyond this group difference, individual differences in the use of these strategies also exist within self‐oriented and other‐oriented decisions.     

Dissociating automatic associations: Comparing two implicit measurements of race bias

Weak correspondence across different implicit bias tasks may arise from the contribution of unique forms of automatic and controlled processes to response behavior. Here, we examined the correspondence between estimates of automatic and controlled processing derived from two sequential priming tasks with identical structure and timing designed to separately measure stereotypic (Weapons Identification Task; WIT) and evaluative (Affective Priming Task; APT) associations. Across two studies using predominantly White samples, three consistent patterns emerged in the data: (a) stereotypic bias was stronger for Black targets, whereas evaluative bias was stronger for White targets; (b) overall response accuracy bias correlated modestly across the two tasks; and (c) multinomial processing tree estimates of controlled processing corresponded much more strongly than estimates of automatic processing. These findings support models positing distinct learning and memory systems for different forms of race bias, and suggest that these differing forms contribute to estimates of automatic associations.
