The effect of early visual deprivation on the development of face processing

We evaluated the importance of early visual input for the later development of expertise in face processing by studying 17 patients, aged 10 to 38 years, treated for bilateral congenital cataracts that deprived them of patterned visual input for the first 7 weeks or more after birth. We administered five computerized tasks that required matching faces on the basis of identity (with changed facial expression or head orientation), facial expression, gaze direction and lip reading. Compared to an age–matched control group, patients’ recognition of facial identity was impaired significantly when there was a change in head orientation (e.g. from frontal to tilted up), and tended to be impaired when there was a change in facial expression (e.g. from happy to surprised). Patients performed normally when matching facial expression and direction of gaze (e.g. looking left or right), and in reading lips (e.g. pronouncing ‘u’ or ‘a’). The results indicate that visual input during early infancy is necessary for the normal development of some aspects of face processing, and are consistent with theories postulating the importance of early visual experience (de Schonen & Mathivet, 1989; Johnson & Morton, 1991) and separate neural mediation of different components of face processing (Bruce & Young, 1986).     

Testing the measurement equivalence of personality adjective items across cultures

Although previous research has examined cross-cultural differences in personality, many of these studies neglected to first establish that the measures being used were equivalent in meaning across cultures. Using samples of Chinese, Greek, and American respondents, the measurement equivalence of the Big Five Mini-Markers [Saucier, G. (1994). Mini-markers: A brief version of Goldberg’s unipolar Big-Five markers. Journal of Personality assessment, 63, 506–516] was assessed using confirmatory factor analysis. The results indicate that all of the scales demonstrate configural invariance, but fail to show metric or scalar invariance. Several adjectives from these scales were found to exhibit bias at the item-level. The practical implications of these results are discussed and future research is suggested.     

Screening for motor coordination challenges in children using teacher ratings of physical ability and activity

We examined the effectiveness of a teacher-based rating scale called the teacher estimation of activity form (TEAF) to screen for developmental coordination disorder (DCD) in children. A random selection of 15 of 75 schools from the District School Board of Niagara in Ontario, Canada was chosen for this study. Every consented child in Grade 4 (n=502) was evaluated for probable DCD (pDCD) in school using the short form Bruininks-Oseretsky test of motor proficiency (BOTMP-SF). Each student also completed the children's self perceptions of adequacy in and predilection toward physical activity (CSAPPA) scale, participation questionnaire, and Léger 20-meter shuttle run, and had their height and weight measured. The 27 children (5.1%) who scored below the 5th percentile on BOTMP-SF were designated as pDCD cases and the 475 children who scored above the 5th percentile served as controls. Results showed that mean TEAF scores were significantly lower for pDCD children than controls (p<.001). Total TEAF scores ranging from 28 to 32 were preferred in maintaining good sensitivity (.74, 95% CI=.55-.87 to .85, 95% CI=.68-.94). The area under the ROC curve was .77 (95% CI, .68-.86) for the TEAF total score, and some individual items performed approximately as well as the full scale. The TEAF was positively correlated with measures of physical activity and fitness. The TEAF appears to be an effective tool in screening for DCD, particularly in a population setting. Considering the brevity of the TEAF and the discriminative power of individual items, this instrument would be effective in an abbreviated version.     

I know how you feel: Task-irrelevant facial expressions are spontaneously processed at a semantic level

Previous studies have demonstrated that emotions are automatically processed. Even with subliminal presentations, subjects involuntarily mimic specific facial expressions, are influenced by the valence of a preceding emotion during judgments, and exhibit slowed responses to personally meaningful emotions; these effects are due to reflexive mimicry, unconscious carryover of valence, and attentional capture, respectively. However, perception-action effects indicate that rapid processing should involve deep, semantic-level representations of emotion (e.g., “fear”), even in the absence of a clinical emotion disorder. To test this hypothesis, we developed an emotional Stroop task (Emostroop) in which subjects responded nonverbally to emotion words superimposed over task-irrelevant images of faces displaying congruent or incongruent emotional expressions. Subjects reliably responded more slowly to incongruent than to congruent stimuli, and this interference was related to trait measures of emotionality. Rapid processing of facial emotions spontaneously activates semantic, content-rich representations at the level of the specific emotion.     

Taking Relationship Seriously in Psychotherapy: Radical Relationality

Psychologists who have historically focused on relationships have tended to underestimate the radical nature of human relationship. A “serious” or an ontological relationality would change the nature of psychotherapy. We describe this change in a discussion of two approaches to relationship, weak and strong relationality. We argue that weak relationality, the general conception of relationship in mainstream psychology, does not ultimately take even the therapeutic relationship seriously. We then discuss and illustrate ten practical implications that a strong relationality would have for psychotherapy.

Action Understanding in the Superior Temporal Sulcus Region

ABSTRACT— The posterior superior temporal sulcus (STS) region plays an important role in the perception of social acts, although its full role has not been completely clarified. This functional magnetic resonance imaging experiment examined activity in the STS region as participants viewed actions that were congruent or incongruent with intentions established by a previous emotional context. Participants viewed an actress express either a positive or a negative emotion toward one of two objects and then subsequently pick up one of them. If the object that was picked up had received positive regard, or if the object that was not picked up had received negative regard, the action was congruent; otherwise, the action was incongruent. Activity in the right posterior STS region was sensitive to the congruency between the action and the actress's emotional expression (i.e., STS activity was greater on incongruent than on congruent trials). These findings suggest that the posterior STS represents not only biological motion, but also how another person's motion is related to his or her intentions.     

(Un)touchability: Disclosure and the Ethics of Loss

In this lyrical essay, I attempt to unravel the complexity behind new modes of HIV prevention and the rise of segregation among people of different antibody status in queer communities. In particular, I question the ease with which disclosure of HIV status is equated with safe sex. Because disclosure often reproduces the power dynamics of confession, I try to imagine an ethics of reciprocity in bearing witness. The essay is perforated by poetic fragments, the way all bodies are perforated, infected or not.
