The Role of the Face and Body in Unfamiliar Person Identification

Information useful for identifying a person can be found both in the face and body. Previous studies indicate that when an entire person is visible, we rely strongly on the face for identification, even if the body can be useful. We measured the utility of the face versus body for identification, by using images of unfamiliar people that varied in the quality of identity information in the face. Face quality was varied using similarity scores generated by state‐of‐the‐art face recognition algorithms from an international competition. These algorithms estimated the similarity of faces in a large set (>1 000 000) of image pairs that showed ‘people’, including the face and the top half of the body. By using these similarity scores, image pairs were stratified into three groups representing good, moderate, and poor performance for the face recognition algorithm. Participants matched identity in image pairs sampled from the three groups, by using versions of the stimuli edited digitally to show only the face or body. Consistent with the algorithm stratifications, performance with the face declined across the three conditions. The face supported more accurate identification than the body in the good and moderate conditions. In the poor condition, performance from the face and body was comparable. Using data from a previous study, we compared the face‐only and body‐only identity judgments with judgments based on the original image. The original unedited image supported the best overall performance in the good and moderate conditions. Notably, performance in the poor condition was equivalent for the face, body, and original images. The results indicate that in poor viewing conditions, identification decisions from the body may be as accurate as those made from the face or the entire person.

On the Variability of Anger Cross-Culturally: An Assessment of General Strain Theory's Primary Mediator

This article assesses general strain theory's (GST) primary mediator, anger, as a process that exhibits important variability across cultures. It presents data from structured interviews and fieldwork in India and the United States that suggest variations in the understanding and experience of anger across three samples: Americans, lay Tibetans, and Tibetan Buddhist clergy. Findings suggest cultural differences in normative social approval of anger, perceived effects for self of becoming angry, reaction tendencies, and emotional memory. Future research should test and map variations in anger across and within populations and explore implications for macro-level GST in explaining cross-cultural differences in crime.     

Using potential performance theory to test five hypotheses about meta-attribution

Based on I. Kant's (1991) distinction between perfect and imperfect duties and the attribution literature pertaining to that distinction, the authors proposed and tested 5 hypotheses about meta-attribution. More specifically, violations of perfect duties have been shown to arouse both more negative affect and stronger correspondent inferences than do violations of imperfect duties (e.g., D. Trafimow, I. K. Bromgard, K. A. Finlay, & T. Ketelaar, 2005). But when it comes to making meta-attributions-that is, guessing the attributions others would make-is the affect differential an advantage or a disadvantage? In addition to the null hypothesis of no effect, the authors proposed and tested additional hypotheses about how negative affect might increase or decrease the effectiveness of people's meta-attribution strategies and how even if there is no effect on strategy effectiveness, negative affect could increase or decrease the consistencies with which these strategies could be used.     

Effects of response bias and judgment framing on operator use of an automated aid in a target detection task

Automated diagnostic aids prone to false alarms often produce poorer human performance in signal detection tasks than equally reliable miss-prone aids. However, it is not yet clear whether this is attributable to differences in the perceptual salience of the automated aids' misses and false alarms or is the result of inherent differences in operators' cognitive responses to different forms of automation error. The present experiments therefore examined the effects of automation false alarms and misses on human performance under conditions in which the different forms of error were matched in their perceptual characteristics. Young adult participants performed a simulated baggage x-ray screening task while assisted by an automated diagnostic aid. Judgments from the aid were rendered as text messages presented at the onset of each trial, and every trial was followed by a second text message providing response feedback. Thus, misses and false alarms from the aid were matched for their perceptual salience. Experiment 1 found that even under these conditions, false alarms from the aid produced poorer human performance and engendered lower automation use than misses from the aid. Experiment 2, however, found that the asymmetry between misses and false alarms was reduced when the aid's false alarms were framed as neutral messages rather than explicit misjudgments. Results suggest that automation false alarms and misses differ in their inherent cognitive salience and imply that changes in diagnosis framing may allow designers to encourage better use of imperfectly reliable automated aids.     

High technology alliances in uncertain times: The case of bluetooth

Research into strategic alliances has traditionally focused on motivation and performance. More recently, network dynamics and alliances as complex and evolving arrangements are emerging areas for investigation. Thus far, little research has been undertaken that integrates these emerging themes in the context of the impact of deteriorating exogenous environments on network alliances. The ICT industry provides such a context, with the rapid deterioration of fortunes in the industry as a result of equity market moves since early 2000. This research looks at the Bluetooth consortium, a loosely framed network of firms involved in the development and commercialization of wireless technical applications for information technology based products. It finds that matters related to intellectual property ownership and inter-firm coordination in complex product development have been problematic, with the deterioration of environmental munificence driving a slowing of network investment and product development success.     

The Animal = Male Hypothesis: Children's and Adults' Beliefs About the Sex of Non–Sex-Specific Stuffed Animals

The Animal = Male Hypothesis, a variation of Silveira's People = Male Hypothesis (Silveira, 1980), was examined. In Study 1, children ages 3–10 years and adults told stories about a gender-neutral stuffed animal, in Study 2 children ages 5–6 years told stories about 3 neutral and 3 feminine animals, and in Study 3 children ages 5–7 years told stories about 2 neutral animals, observed an adult model use feminine pronouns to refer to an animal, then told stories about 2 more animals. Dependent variables were the pronouns participants used to refer to the animals and what sex they believed the animals were. Results showed strong evidence for an animal = male bias in all 3 studies among children and adults of both sexes on both dependent measures. There were few sex-related differences. The modeling intervention was not successful in reducing the bias.     

Perfectionism and Obsessive-Compulsive Symptoms

This study was designed to determine whether perfectionism, as assessed by the revised almost perfect scale (APS-R; R. B. Slaney, M. Mobley, J. Trippi, J. S. Ashby, & D. G. Johnson, 1996), was a significant predictor of obsessive-compulsive (OC) symptoms in a non-clinical sample of 308 university students. Perfectionistic discrepancy emerged as a general predictor of obsessive thought difficulties and compulsive checking behavior. Excessive concerns about making mistakes also emerged as a significant specific predictor of obsessive cognitive but not behavioral symptoms after other dimensions of perfectionism were controlled. An interaction effect indicated that students with high discrepancy but low standards were more likely to experience OC-related washing symptoms than other students. The general effects of perfectionism on OC symptoms, the specific effects of certain perfectionism dimensions over others, and other perfectionism research results, implicate APS-R discrepancy as a core dimension of maladaptive perfectionism and APS-R high standards as either benign or protective in the associations with OC symptoms.     

Perfectionism,Shame, and Depressive Symptoms

The authors examined the relationship between depression, maladaptive perfectionism, and shame. Regression analyses were used to replicate a model in which maladaptive perfectionism was negatively associated with self‐esteem and positively associated with symptoms of depression, with self‐esteem mediating the effects of maladaptive perfectionism on depressive symptoms. Additional models showed that the path from maladaptive perfectionism to depression was partially mediated by shame, although these paths differed for men and women.
