The perception of a familiar face is no more than the sum of its parts

Why do faces become easier to recognize with repeated exposure? Previous research has suggested that familiarity may induce a qualitative shift in visual processing from an independent analysis of individual facial features to analysis that includes information about the relationships among features (Farah, Wilson, Drain, & Tanaka Psychological Review, 105, 482–498, 1998; Maurer, Grand, & Mondloch Trends in Cognitive Science, 6, 255–260, 2002). We tested this idea by using a “summation-at-threshold” technique (Gold, Mundy, & Tjan Psychological Science, 23, 427–434, 2012; Nandy & Tjan Journal of Vision, 8, 3.1–20, 2008), in which an observer’s ability to recognize each individual facial feature shown independently is used to predict their ability to recognize all of the features shown in combination. We find that, although people are better overall at recognizing familiar as opposed to unfamiliar faces, their ability to integrate information across features is similar for unfamiliar and highly familiar faces and is well predicted by their ability to recognize each of the facial features shown in isolation. These results are consistent with the idea that familiarity has a quantitative effect on the efficiency with which information is extracted from individual features, rather than a qualitative effect on the process by which features are combined.     

The religious person revisited: cross-cultural evidence from the HEXACO model of personality structure

The relationship of religiousness with the HEXACO (Honesty-Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, Openness) model of personality was studied in Iran and the United States. Correlations of personality factors and religiousness were generally similar across the two societies. In both countries, religiousness was associated with higher scores on Honesty-Humility, Extraversion, Agreeableness, and Conscientiousness. The Honesty-Humility factor was one of the strongest correlates of religiousness in both countries. These findings support Saroglou's observation that the main personality characteristics of religiousness are consistent across different religious contexts and personality measures and models.     

Moderators of the association between exercise identity and obligatory exercise among participants of an athletic event

Previous research has connected exercise identity with obligatory exercise, yet to date no empirical studies have identified moderator variables of this association. The current study included participants of an athletic event (full marathon, n = 582; half marathon, n = 1,106; shorter distance, n = 733) who completed questionnaires about exercise behaviors, obligatory exercise, and internalization of both the thin-ideal and athletic-ideal body shapes. General linear model analyses were conducted to examine the exercise identity–obligatory exercise relationship; moderator variables included gender, internalization of the thin-ideal body shape, and internalization of the athletic-ideal body shape. After controlling for the effects of body mass index, age, and distance group, the three-way interaction of exercise identity, gender, and internalization of the athletic-ideal body shape predicted obligatory exercise. Findings suggest that women who report high identification with exercise and high value on having an athletic physique may be vulnerable to obligatory exercise.     

Inhibition of return is at the midpoint of simultaneous cues

When multiple cues are presented simultaneously, Klein, Christie, and Morris (Psychonomic Bulletin & Review 12:295–300, 2005) found a gradient of inhibition (of return, IOR), with the slowest simple manual detection responses occurring to targets in the direction of the center of gravity of the cues. Here, we explored the possibility of extending this finding to the saccade response modality, using methods of data analysis that allowed us to consider the relative contributions of the distance from the target to the center of gravity of the array of cues and the nearest element in the cue array. We discovered that the bulk of the IOR effect with multiple cues, in both the previous and present studies, can be explained by the distance between the target and the center of gravity of the cue array. The present results are consistent with the proposal advanced by Klein et al., (2005) suggesting that this IOR effect is due to population coding in the oculomotor pathways (e.g., the superior colliculus) driving the eye movement system toward the center of gravity of the cued array.     

The Assessment and Diagnosis of Attention Deficit Hyperactivity Disorder in Adult Forensic Psychiatric Outpatients

The primary purpose of the present study was to examine the validity of commonly utilized ADHD rating scales within an adult forensic population. Participants were 120 patients assessed for dysfunctional anger and impulsive aggression at a hospital-based clinic. Two psychiatrists made independent diagnoses about the presence or absence of ADHD among individuals presenting with symptoms consistent with this disorder. Following the diagnoses, participants were assessed with multiple ADHD measures, including measures based on self-report, observer-report, or a computerized neuropsychological measure (IVA + Plus). With the exception of the IVA + Plus, the ADHD measures significantly differentiated individuals diagnosed with ADHD from individuals who were not so diagnosed. These measures also demonstrated good diagnostic utility via test specific parameters (sensitivity, specificity, positive predictive power, and negative predictive power). A sub-set of measures demonstrated particularly good classification accuracy, with high sensitivity (91 %) and good specificity (81 %). Implications of these findings for the effective assessment and diagnosis of ADHD in adult outpatient psychiatric settings are discussed.     

The Shedler–Westen Assessment Procedure (SWAP): Making Personality Diagnosis Clinically Meaningful

A group of 38 severe anxiety patients and a group of 36 acute schizophrenic patients produced series of afterimages (AIs) of a simple, red stimulus. It was predicted that projective tendencies in these patients would be revealed by lack of stable congruence between AI color and stimulus. Symptoms of sensitivity together with results from the MCT (Meta-Contrast Technique) served as criteria in the anxiety group and symptoms of paranoia in the schizophrenic group. The hypothesis was affirmed: despite the unicolored stimulation, sensitive and paranoid subjects tended to report variegated A1s or A1s shifting from one color to another. It was concluded that, in case this plastic type of perception remains more or less permanent, it would serve as a fruitful breeding-ground for projective defenses.     

The Holtzman Inkblot Technique as a Measure of Perceptual Development in Mental Retardation

To investigate the relationships between mental age and scores from the Holtzman Inkblot Technique (HIT), 96 mentally retarded and normal Ss comprising four criterion IQ-groups ranging in IQ from 34 to 106 were tested. Each group was matched for sex and chronological age. Results revealed consistent monotonic changes with IQ level for six HIT variables, including four that previously had proved to be reliable and meaningful indices of perceptual development. These results provide strong support for these HIT variables as indices of perceptual development and confirm the nature and direction of this development.     

The solace of radicalism: Self-uncertainty and group identification in the face of threat

From uncertainty–identity theory, it was hypothesized that where people feel their self-relevant values and practices are under threat, self-uncertainty strengthens identification with “radical” groups, and either has no effect on or weakens identification with “moderate” groups. Since this hypothesis was tested on Australian students, who prefer to identify with moderate groups, the context-specific expectation was for that preference to disappear under uncertainty. This prediction was confirmed by a laboratory experiment in which self-uncertainty and group radicalism were manipulated in a 2 × 2 design (N = 82); the preference to identify with a moderate over a radical group disappeared under uncertainty because uncertainty strengthened identification with the radical group. This effect was directly mirrored in people's intentions to engage in specific group behaviors, and behavioral intentions were mediated by identification. The research is framed by a discussion of the relationship between uncertainty and social extremism, and implications for future research are noted.
