Audiovisual identity perception from naturally-varying stimuli is driven by visual information

Identity perception often takes place in multimodal settings, where perceivers have access to both visual (face) and auditory (voice) information. Despite this, identity perception is usually studied in unimodal contexts, where face and voice identity perception are modelled independently from one another. In this study, we asked whether and how much auditory and visual information contribute to audiovisual identity perception from naturally-varying stimuli. In a between-subjects design, participants completed an identity sorting task with either dynamic video-only, audio-only or dynamic audiovisual stimuli. In this task, participants were asked to sort multiple, naturally-varying stimuli from three different people by perceived identity. We found that identity perception was more accurate for video-only and audiovisual stimuli compared with audio-only stimuli. Interestingly, there was no difference in accuracy between video-only and audiovisual stimuli. Auditory information nonetheless played a role alongside visual information as audiovisual identity judgements per stimulus could be predicted from both auditory and visual identity judgements, respectively. While the relationship was stronger for visual information and audiovisual information, auditory information still uniquely explained a significant portion of the variance in audiovisual identity judgements. Our findings thus align with previous theoretical and empirical work that proposes that, compared with faces, voices are an important but relatively less salient and a weaker cue to identity perception. We expand on this work to show that, at least in the context of this study, having access to voices in addition to faces does not result in better identity perception accuracy.     

Therapist Self-disclosure and Culturally Competent Care with Mexican–American Court Mandated Clients: A Phenomenological Study

Therapist self-disclosure (TSD) is a skill with numerous potential benefits and risks for the therapeutic alliance. While its effects have been established, little empirical research has examined the impact of TSD in cross-cultural treatment settings with court-mandated clients, a context with unique considerations. In an effort to help fill this gap, results of a phenomenological study examining the effects of TSD on Mexican–American men working with Anglo American therapists in a mandated treatment setting are presented. The results of this study indicate that TSD is a culturally competent intervention with several benefits for mandated clients, including strengthening the therapeutic alliance, normalizing client problems, lessening the therapist-client hierarchy, and modeling the acceptability of self-disclosure. Clinical and marriage and family therapy educational implications are also discussed.     

The role of human body movements in mate selection

It is common scientific knowledge, that most of what we say within a conversation is not only expressed by the words' meaning alone, but also through our gestures, postures, and body movements. This non-verbal mode is possibly rooted firmly in our human evolutionary heritage, and as such, some scientists argue that it serves as a fundamental assessment and expression tool for our inner qualities. Studies of nonverbal communication have established that a universal, culture-free, non-verbal sign system exists, that is available to all individuals for negotiating social encounters. Thus, it is not only the kind of gestures and expressions humans use in social communication, but also the way these movements are performed, as this seems to convey key information about an individual's quality. Dance, for example, is a special form of movement, which can be observed in human courtship displays. Recent research suggests that people are sensitive to the variation in dance movements, and that dance performance provides information about an individual's mate quality in terms of health and strength. This article reviews the role of body movement in human non-verbal communication, and highlights its significance in human mate preferences in order to promote future work in this research area within the evolutionary psychology framework.     

Combined effects of inversion and feature removal on N170 responses elicited by faces and car fronts

The face-sensitive N170 is typically enhanced for inverted compared to upright faces. Itier, Alain, Sedore, and McIntosh (2007) recently suggested that this N170 inversion effect is mainly driven by the eye region which becomes salient when the face configuration is disrupted. Here we tested whether similar effects could be observed with non-face objects that are structurally similar to faces in terms of possessing a homogeneous within-class first-order feature configuration. We presented upright and inverted pictures of intact car fronts, car fronts without lights, and isolated lights, in addition to analogous face conditions. Upright cars elicited substantial N170 responses of similar amplitude to those evoked by upright faces. In strong contrast to face conditions however, the car-elicited N170 was mainly driven by the global shape rather than the presence or absence of lights, and was dramatically reduced for isolated lights. Overall, our data confirm a differential influence of the eye region in upright and inverted faces. Results for car fronts do not suggest similar interactive encoding of eye-like features and configuration for non-face objects, even when these objects possess a similar feature configuration as faces.     

The contributions of encoding,retention, and recall to the Hebb effect

The article reports an experiment testing whether the Hebb repetition effect—the gradual improvement of immediate serial recall when the same list is repeated several times—depends on overt recall of the repeated lists. Previous reports which suggest that recall is critical confound the recall manipulation with retention interval. The present experiment orthogonally varies retention interval (0 or 9 s) and whether the list is to be recalled after the retention interval. Hebb repetition learning is assessed in a final test phase. A repetition effect was obtained in all four experimental conditions; it was larger for recalled than non-recalled lists, whereas retention interval had no effect. The results show that encoding is sufficient to generate cumulative long-term learning, which is strengthened by recall. Rehearsal, if it takes place in the retention interval at all, does not have the same effect on long-term learning as overt recall.     

Social Participation During Transition to Adult Life Among Young Adults With High-Functioning Autism Spectrum Disorders: Experiences From an Exploratory Multiple Case Study

This study aimed to explore the social participation of young adults with high-functioning autism spectrum disorders (HFASD) during their transition to adult life. A multiple case study was conducted using semi-structured interviews with a purposive sample of 10 participants (n = 10) composed of three adults with HFASD, their caregivers, and two representatives of community organizations. Four themes emerged: (1) access to services, (2) orientation to integrated life goals, (3) engagement in meaningful activities, and (4) gap in services before reaching independent living. Properly preparing and orienting the families could help them have a more satisfying social participation.     

Refining Therapeutic Mandates in Couple Therapy Outcome Research: A Feasibility Study

Using a series of 59 cases of couple therapy, we studied the nature, frequency, and pre-treatment correlates of therapeutic mandates. Following intake, therapists coded mandate and couples completed the Dyadic Adjustment Scale and the Relationship Attribution Measure. The distribution of therapeutic mandates showed that 45.8% wished to improve an overtly conflictual relationship, 28.8% consulted to remedy a lack of love and/or desire, and 25.4% aimed to change a specific aspect of an otherwise well-functioning relationship. Over the course of treatment, in 20% of cases, the therapeutic mandate was revised and adjusted. The results of a logistic regression analysis showed that mandate subgroups, men's marital satisfaction, women's responsibility attributions, and women's income are significantly associated with termination status.
