Processing Differences between Feature‐Based Facial Composites and Photos of Real Faces

Computer‐generated faces (composites) constructed by select2ing individual facial features (e.g. eyes, nose, mouth) are poorly recognized because this process contrasts with the natural holistic processing of real faces. This result suggests that there should be differences in the cognitive processing of these composites compared with photos of real faces, which would make these stimuli problematic for theories seeking to explain real face processing. We conducted five experiments to test potential conditions for moving composite processing closer to how real face photos are processed, first taking the perspective of researchers who construct composites with a random selection of available features and then taking a perspective closer to police by creating each composite to match a real face photo. Composites with randomly selected features (but configured like real faces) showed no face inversion effect and recognition memory for these composites benefited from increased encoding time, unlike real face photos. Although composites constructed to match real face photos yielded an inversion effect, they still were remembered differently than the photos. Researchers should not use feature‐based composites as proxies for real face photos. We conclude with a discussion of alternative methods of constructing composites.

The relativity of grief: Differential adaptation reactions of younger and older persons

Abstract

A study was conducted to investigate the differential emotional and coping responses of 41 older (M = 66.5 years) and 48 younger (M = 23.5 years) respondents who had recently lost a close loved one to death. Respondents completed a questionnaire in which they gave an account of the death of their loved one, information about how they coped with this loss, and responses concerning their emotions pertaining to the loss. As predicted, older respondents reported a higher degree of account-making (i.e., story-like constructions) about their losses and confiding in close others than did younger respondents. Further, older respondents showed fewer negative and more positive responses than younger respondents. These results were interpreted to suggest that older respondents were less acutely devastated by their losses and are consistent with the idea that     

Self-Images without Awareness and Projective Methods of Personality Assessment

Ss' responses to tachistoscopic exposures of self-photographs have been suggested as one approach to self-images without awareness. Sixty-three Ss completed a Q sort for themselves and after tachistoscopic exposure of their own and control photographs, for the persons in the photographs. Ss also completed the Structured-Objective Rorschach Test and Rotter Incomplete Sentences Blank. The self was sorted most favorably, the control tachistoscopic exposure significantly less favorably, and the self tachistoscopic exposure significantly less favorably than the control. These differences were found to be related to sex and adjustment measured with the Rotter. The SORT correlated insignificantly with Q sort and Rotter.     

Generalized extensive measurement for lexicographic orders

Theories of extensive measurement usually assume an “Archimedean axiom”, designed to exclude the possibility of infinite or infinitesimal differences among the objects of measurement. The standard theories are therefore not applicable to structures containing lexicographic orders. In this paper, a generalized theory of extensive measurement is developed, which allows infinite and infinitesimal differences. The theory has potential applications in areas such as value and preference research, where lexicographically ordered structures are common. Our result is fully analogous to the standard representation and uniqueness theorem of extensive measurement, and only simple and familiar mathematical concepts are assumed.     

Spatial attention-related modulation of the N170 by backward masked fearful faces

Facial expressions are a basic form of non-verbal communication that convey important social information to others. The relevancy of this information is highlighted by findings that backward masked facial expressions facilitate spatial attention. This attention effect appears to be mediated through a neural network consisting of the amygdala, anterior cingulate, and visual cortex. However, a direct investigation of the neural time course associated with orienting to such stimuli has yet to be performed. In the current investigation, a backward masked fearful face dot-probe task was performed while ERPs were recorded. Reaction time results suggest that spatial attention is captured by backward masked fearful faces and attention is focused at the location of the fear stimulus. Masked right visual field fearful faces enhanced the N170 amplitudes of contralateral occipito-temporal electrodes. The rapid contralateral N170 enhancement was positively correlated with participants’ behavioral index of spatial attention. Thus, backward masked fearful face-elicited spatial attention facilitates behavior and modulates the early stage of facial processing reflected by the N170.     

Externalizing behavior,the UPPS-P Impulsive Behavior scale and Reward and Punishment Sensitivity

The UPPS-P Impulsive Behavior scale is a promising measure of impulsivity facets involved in the etiology of Externalizing behaviors (e.g., substance abuse, antisocial behavior, and aggression). The purpose of this study was to determine whether measures of motivational systems, specifically Reward and Punishment Sensitivity, accounted for variance in Externalizing behaviors beyond the UPPS-P scales. Undergraduates (N = 282; 50% men) completed online self-reports of alcohol and drug use, antisocial behavior, and aggression, as well as the UPPS-P and measures of Reward and Punishment Sensitivity. Principal components analysis was used to create summary Externalizing scores related to Disinhibition and Aggression. Lack of Premeditation, low Perseverance and Sensation Seeking had significant partial relationships with Disinhibition, but Reward Sensitivity accounted for additional variance. Both Reward Sensitivity and (Low) Punishment Sensitivity were related to Aggression, beyond variance explained by UPPS-P Negative Urgency and (lack of) Perseverance. Impulsivity facets appear to have differential relationships with measures of Externalizing and, although the UPPS-P accounts for a significant portion of individual differences, it does not fully account for variance associated with Reward and Punishment Sensitivity.     

Dispositional mindfulness,insomnia, sleep quality and dysfunctional sleep beliefs in post-treatment cancer patients

Dispositional mindfulness, or the tendency to be more mindful in daily life, has been associated with better psychological functioning and reduced overall distress. This study investigated the degree to which dispositional mindfulness was associated with sleep disturbances in cancer patients with insomnia. Further, we examined whether levels of mindfulness moderated the relationship between stress levels, mood disturbance, insomnia severity, sleep quality and dysfunctional sleep beliefs. Participants (N = 111) were adults who had been previously treated for cancer and currently met diagnostic criteria for insomnia. Higher levels of acting with awareness, non-judging and non-reacting were associated with better sleep and psychological outcomes. Despite these significant associations, mindfulness facets did not significantly moderate the relationship between stress, mood and sleep outcomes. This negative finding raises the possibility that increased mindfulness may not act directly to improve psychological outcomes, but rather through a series of other cognitive and affective changes. Our results emphasize the importance of addressing mood symptoms and stress appraisals as predictors of sleep disturbance in cancer patients.     

The effect of viewing distance on empirical discriminability and the confidence–accuracy relationship for eyewitness identification

The distance from which an eyewitness views a perpetrator is a critical factor for eyewitness identification, but has received little research attention. We presented three mock-crime videos to participants, varying distance to three perpetrators (3, 10, or 20 m). Across two experiments, increased distance reduced empirical discriminability in the form of a mirror effect, such that correct identifications decreased while false identifications increased. Moreover, high confidence identifications were associated with high accuracy at 3 m (Experiment 1 and 2) and 10 m (Experiment 2), but not at 20 m. We conclude that eyewitnesses may be less likely to identify a perpetrator viewed at a distance, and also more likely to falsely identify an innocent suspect. Furthermore, there may be certain boundary conditions associated with distance and the impact it has on the confidence–accuracy relationship. More research is needed to elucidate the effect of estimator variable manipulations on the confidence–accuracy relationship.
