Mixed emotions: holistic and analytic perception of facial expressions

In the face literature, it is debated whether the identification of facial expressions requires holistic (i.e., whole face) or analytic (i.e., parts-based) information. In this study, happy and angry composite expressions were created in which the top and bottom face halves formed either an incongruent (e.g., angry top + happy bottom) or congruent composite expression (e.g., happy top + happy bottom). Participants reported the expression in the target top or bottom half of the face. In Experiment 1, the target half in the incongruent condition was identified less accurately and more slowly relative to the baseline isolated expression or neutral face conditions. In contrast, no differences were found between congruent and the baseline conditions. In Experiment 2, the effects of exposure duration were tested by presenting faces for 20, 60, 100 and 120 ms. Interference effects for the incongruent faces appeared at the earliest 20 ms interval and persisted for the 60, 100 and 120 ms intervals. In contrast, no differences were found between the congruent and baseline face conditions at any exposure interval. In Experiment 3, it was found that spatial alignment impaired the recognition of incongruent expressions, but had no effect on congruent expressions. These results are discussed in terms of holistic and analytic processing of facial expressions.     

Implicit transfer of spatial structure in visuomotor sequence learning

Implicit learning and transfer in sequence learning are essential in daily life. Here, we investigated the implicit transfer of visuomotor sequences following a spatial transformation. In the two experiments, participants used trial and error to learn a sequence consisting of several button presses, known as the m × n task (Hikosaka et al., 1995). After this learning session, participants learned another sequence in which the button configuration was spatially transformed in one of the following ways: mirrored, rotated, and random arrangement. Our results showed that even when participants were unaware of the transformation rules, accuracy of transfer session in the mirrored and rotated groups was higher than that in the random group (i.e., implicit transfer occurred). Both those who noticed the transformation rules and those who did not (i.e., explicit and implicit transfer instances, respectively) showed faster performance in the mirrored sequences than in the rotated sequences. Taken together, the present results suggest that people can use their implicit visuomotor knowledge to spatially transform sequences and that implicit transfers are modulated by a transformation cost, similar to that in explicit transfer.     

Losing face: impaired discrimination of featural and configural information in the mouth region of an inverted face

Given that all faces share the same set of features—two eyes, a nose, and a mouth—that are arranged in similar configuration, recognition of a specific face must depend on our ability to discern subtle differences in its featural and configural properties. An enduring question in the face-processing literature is whether featural or configural information plays a larger role in the recognition process. To address this question, the face dimensions task was designed, in which the featural and configural properties in the upper (eye) and lower (mouth) regions of a face were parametrically and independently manipulated. In a same–different task, two faces were sequentially presented and tested in their upright or in their inverted orientation. Inversion disrupted the perception of featural size (Exp. 1), featural shape (Exp. 2), and configural changes in the mouth region, but it had relatively little effect on the discrimination of featural size and shape and configural differences in the eye region. Inversion had little effect on the perception of information in the top and bottom halves of houses (Exp. 3), suggesting that the lower-half impairment was specific to faces. Spatial cueing to the mouth region eliminated the inversion effect (Exp. 4), suggesting that participants have a bias to attend to the eye region of an inverted face. The collective findings from these experiments suggest that inversion does not differentially impair featural or configural face perceptions, but rather impairs the perception of information in the mouth region of the face.     

Repetition priming of access to biographical information from faces

Two experiments examined repetition priming on tasks that require access to semantic (or biographical) information from faces. In the second stage of each experiment, participants made either a nationality or an occupation decision to faces of celebrities, and, in the first stage, they made either the same or a different decision to faces (in Experiment 1) or the same or a different decision to printed names (in Experiment 2). All combinations of priming and test tasks produced clear repetition effects, which occurred irrespective of whether the decisions made were positive or negative. Same-domain (face-to-face) repetition priming was larger than cross-domain (name-to-face) priming, and priming was larger when the two tasks were the same. It is discussed how these findings are more readily accommodated by the Burton, Bruce, and Johnston () model of face recognition than by episode-based accounts of repetition priming.     

Pulsed electrodeposition of soft magnetic CoNiFe films under centrifugal forces

A new technique, pulsed electrodeposition under a centrifugal force, is introduced for the preparation of soft magnetic CoNiFe films. The films have enhanced properties such as a high B _s (magnetic saturation) and a low H _c (coercivity), which are desirable for soft magnetic materials. They are also smoother than films deposited under non-pulsed conditions. It is suggested that the technique could be used to prepare various other materials with desirable properties.     

Stress,coping, and depressive symptomatology in Latina and Anglo aids caregivers

In a survey of 432 AIDS caregivers, we examined differences in the stress and coping process and predictors of depressive symptomatology by ethnicity and gender. Our sample included 192 Anglo gay and bisexual male partners, 86 Anglo women, and 154 Latina family caregivers. We examined differences in primary and secondary stressors as predictors of depression; differences in sociodemographic and background factors, and differences in the predictive value and mediating influences of factors that may attenuate the relationship between stress and depression. Results indicate substantial differences in predictors and mediators of depression across groups. While all groups evidenced moderate levels of depression, background factors influenced depression mostly for Latinas. Depression in gay and bisexual partners was more influenced by primary objective stressors such as assisting with activities of daily living (ADLs). Service acquisition appears to be shaped by access, knowledge, and cultural acceptance. Based on our findings, we suggest that service provision for caregivers must also vary and be attuned to cultural and gender differences that may influence perception of stress and depression for caregivers.     

Cross-sectional and Longitudinal associations in coping strategies and physical health outcomes among HIV-Positive youth

This study assessed whether coping styles had an influence on physical health outcomes either concurrently or longitudinally in a sample of HIV-positive youth. Coping styles were characterized as positive, passive, depressive withdrawal, and escapist. A cross-sectional latent variable analysis (N = 279) assessed associations among environmental stress, self-esteem, social support, coping styles, AIDS symptoms, and CD4 count. A more restricted longitudinal analysis (N = 174) tested associations among earlier environmental stress, self-esteem, coping styles, and AIDS symptoms at follow-up. CD4 count was not associated with coping styles in the cross-sectional analysis. Concurrent AIDS symptoms were significantly predicted by depressive withdrawal and environmental stress. A passive coping style modestly predicted more AIDS symptoms longitudinally. Correlates of perceived health and well-being of persons with HIV/AIDS are important to investigate in addition to more objective measures such as CD4 count that may not be amenable to change through coping style interventions alone.     

Perceptual expertise and the plasticity of other-race face recognition

In this paper, we argue that our ability to recognize own-race faces can be treated as a form of perceptual expertise. Similar to object experts (e.g., birdwatchers), people differentiate own-race faces at the subordinate level of categorization. In contrast, like novices, we tend to classify other-race faces at the basic level of race. We demonstrate that, as a form of perceptual expertise, other-race face recognition can be systematically taught in the lab through subordinate-level training. When participants learn to quickly and accurately differentiate other-race faces at the subordinate level of the individual, the individuating training transfers to improved recognition of untrained other-race faces, produces changes in event-related brain components, and reduces implicit racial bias. Subsequent work has shown that other-race learning can be optimized by directing participants to the diagnostic features of a racial group. The benefits of other-race training are fairly long-lived and are evident even 2 weeks after training. Collectively, the training studies demonstrate the plasticity of other-race face recognition. Rather than a process that is fixed by early developmental events, other-race face recognition is malleable and dynamic, continually being reshaped by the perceptual experiences of the observer.     

Major Psychological Factors Determining Public Acceptance of the Siting of Nuclear Facilities

The purpose of this study was to examine the hypothesis that factors that determine public acceptance of nuclear facilities in a general situation are different from factors that determine public acceptance of nuclear facilities in a siting situation by using a causal model. A survey was conducted in Japan with 1,000 randomly selected adult participants. The results were that in a general situation, both perceived risk and perceived benefit are important for public acceptance of nuclear facilities. In addition, in a siting situation, perceived risk is very important for public acceptance of nuclear facilities, whereas perceived benefit has little importance for public acceptance. Thus, for discussions concerning public acceptance of a facility associated with risk, it is important to clarify whether the viewpoint of a general situation or the viewpoint of a siting situation should be adopted.
