Attentional capture by irrelevant emotional distractor faces is contingent on implicit attentional settings

Although expressions of facial emotion hold a special status in attention relative to other complex objects, whether they summon our attention automatically and against our intentions remains a debated issue. Studies supporting the strong view that attentional capture by facial expressions of emotion is entirely automatic reported that a unique (singleton) emotional face distractor interfered with search for a target that was also unique on a different dimension. Participants could therefore search for the odd-one out face to locate the target and attentional capture by irrelevant emotional faces might be contingent on the adoption of an implicit set for singletons. Here, confirming this hypothesis, an irrelevant emotional face captured attention when the target was the unique face with a discrepant orientation, both when this orientation was unpredictable and when it remained constant. By contrast, no such capture was observed when the target could not be found by monitoring displays for a discrepant face and participants had to search for a face with a specific orientation. Our findings show that attentional capture by emotional faces is not purely stimulus driven and thereby resolve the apparent inconsistency that prevails in the literature on the automaticity of attentional capture by emotional faces.     

Asymmetry between encoding and retrieval processes: Evidence from divided attention and a calibration analysis

Two experiments provide further information on the effects of divided attention (DA) on encoding and retrieval processes. The first experiment examined the effects of decision and motor difficulty of a concurrent reaction time task. A calibration analysis was used in the second experiment to test the hypothesis that shifting attentional emphasis away from encoding to the secondary task reduces the level of processing the to-be-remembered items receive. Overall, the results confirm and extend the conclusions of Craik, Govoni, Naveh-Benjamin, and Anderson (1996) and Naveh-Benjamin, Craik, Guez, and Dori (1998), by pointing to clear differences between encoding and retrieval processes: Encoding is affected by simultaneous task demands, especially those associated with "central" resources involved in conscious decision making, whereas retrieval is obligatory in that it is largely immune to the effects of simultaneous demands. The results of the calibration analysis suggest that one reason for the poorer memory performance as a result of DA at encoding is a qualitative shift to less deep, elaborative strategies.     

Humans prefer curved visual objects

People constantly make snap judgments about objects encountered in the environment. Such rapid judgments must be based on the physical properties of the targets, but the nature of these properties is yet unknown. We hypothesized that sharp transitions in contour might convey a sense of threat, and therefore trigger a negative bias. Our results were consistent with this hypothesis. The type of contour a visual object possesses--whether the contour is sharp angled or curved--has a critical influence on people's attitude toward that object.     

Rotting with their rights on: why the criteria for ending commitment or restraint of liberty need not be the same as the criteria for initiating commitment or restraint of liberty, and how the restraint may sometimes justifiably continue after its prerequisites are no longer satisfied

That coerced treatment must end when the criteria for initiating coerced treatment cease to apply appears to be universally accepted by courts and commentators.2 Moreover, the consensus appears to be justified by a steel-trap argument. If coercion is justified only when the patient is mentally ill and incapable, because then the patient lacks autonomous capacities, or lacks practical reasoning abilities that undercut autonomous capacities, then these justifications have no force when the patient either is not mentally ill or is capable. A parallel claim holds for civil commitment. This received wisdom, or in = out thesis, rests upon a conceptual confusion: a failure to distinguish the criteria for initiation of intervention, those for cessation of intervention, and the purpose of the commitment or coerced treatment. If the criteria for commitment were mental illness and dangerousness, and the criteria for release were the same, then the purpose of commitment would be to restore persons to the point where they are either just barely not mentally ill, or just barely not dangerous. That is a silly and self-defeating purpose for that large class of patients who, because of lack of insight, or otherwise, do not become treatment compliant until they are substantially healthier than being barely not mentally ill or barely not dangerous. It sets them up to become revolving-door patients. The purpose of commitment is rather to maximize the patient's mental health, and minimize her dangerousness without unduly burdening her liberty. If society is going to violate a patient's liberty, it should do so in a way that will resolve the problem that justified the restriction on liberty in the first place, so long as the restriction of liberty is not too great in relation to the expected gains from the intervention. The criteria for releasing a patient from commitment are in this way responsive to the purpose of the commitment. For some revolving-door patients, this entails that the criteria for their release from commitment should be stricter than the criteria for initiating commitment in the first place. The criteria for release from commitment for revolving-door patients should be that the criteria for initiation for commitment is not met plus it being more likely than not that the patient will be treatment compliant after release, assuming the additional restriction on liberty is less than the gains from the additional restraint, and the restriction is not unduly burdensome. Spelling this out, the criteria for release should be either not mentally ill, or else not dangerous, or capable, and more likely than not to be treatment compliant after release. For those patients for whom such a test is overly optimistic, we might substitute that there is a reasonable probability of treatment compliance after release, or that the probability of treatment compliance has been enhanced. These criteria are to be thought of as rough and ready rules of thumb, and not as analytically precise tests.     

Very first impressions

First impressions of people's personalities are often formed by using the visual appearance of their faces. Defining how quickly these impressions can be formed has critical implications for understanding social interactions and for determining the visual properties used to shape them. To study impression formation independent of emotional cues, threat judgments were made on faces with a neutral expression. Consequently, participants' judgments pertained to the personality rather than to a certain temporary emotional state (e.g., anger). The results demonstrate that consistent first impressions can be formed very quickly, based on whatever information is available within the first 39 ms. First impressions were less consistent under these conditions when the judgments were about intelligence, suggesting that survival-related traits are judged more quickly. The authors propose that low spatial frequencies mediate this swift formation of threat judgments and provide evidence that supports this hypothesis.     

The effects of divided attention at encoding on item and associative memory

Divided attention at encoding is well known to have adverse effects on episodic memory performance (e.g., Naveh-Benjamin & Greg, 2000). This article attempts to determine whether these effects are a result of the interruption of encoding of associative information among the components of an episode. Five experiments, using different types of episodes and episodes components, were conducted. Participants studied information under either full or divided attention and were then tested on their memory for both the episodes' components and the associations between them. Divided attention did not produce a differential deficit in memory for associative information; memory for the components suffered to the same degree as memory for the associations among the components. The cause of the divided-attention effect at encoding lies somewhere other than in the associative processes that are engaged.     

Adult age differences in episodic memory: further support for an associative-deficit hypothesis

This study further tested an associative-deficit hypothesis (ADH; M. Naveh-Benjamin, 2000), which attributes a substantial part of older adults' deficient episodic memory performance to their difficulty in merging unrelated attributes-units of an episode into a cohesive unit. First, the results of 2 experiments replicate those observed by M. Naveh-Benjamin (2000) showing that older adults are particularly deficient in memory tests requiring associations. Second, the results extend the type of stimuli (pictures) under which older adults show this associative deficit. Third, the results support an ADH in that older adults show less of an associative deficit when the components of the episodes used are already connected in memory, thereby facilitating their encoding and retrieval. Finally, a group of younger adults who encoded the information under divided-attention conditions did not show this associative deficit.     

Developmental prosopagnosia: a review

This article reviews the published literature on developmental prosopagnosia, a condition in which the ability to recognize other persons by facial information alone has never been acquired. Due to the very low incidence of this syndrome, case reports are sparse. We review the available data and suggest assessment strategies for patients suffering from developmental prosopagnosia. It is suggested that developmental prosopagnosia is not a unitary condition but rather consists of different subforms that can be dissociated on the grounds of functional impairments. On the basis of the available evidence, hypotheses about the aetiology of developmental prosopagnosia as well as about the selectivity of deficits related to face recognition are discussed.     

Evaluation of Coworker Turnover Outcomes and Its Impact on the Intention to Leave of the Remaining Employees

The study examined the effect of several personal and situational variables upon stayers' intention to leave, subsequent to the departure of a coworker. These effects were hypothesized to be mediated by the stayers' evaluation of outcomes of the departure. Police officers filled questionnaires prior to and within one month subsequent to turnover of a coworker. The theoretical model was tested via hierarchical multiple regression. Negative and positive evaluations were independent: They were differentially associated with the predictor variables and they varied in their effect upon the criterion measure. The mediation hypothesis was not supported; the negative evaluation of departure outcomes was indeed predicted by the independent variables but it was not associated with the intention to leave subsequent to a coworker's departure. Positive evaluation, on the other hand, was not predicted by the independent variables but was significantly and positively correlated with the criterion measure. Contrary to the hypothesis, stayers who perceive coworkers' departure as more positive show a stronger tendency to leave.
