Selective attention to a talker's mouth in infancy: role of audiovisual temporal synchrony and linguistic experience

Previous studies have found that infants shift their attention from the eyes to the mouth of a talker when they enter the canonical babbling phase after 6 months of age. Here, we investigated whether this increased attentional focus on the mouth is mediated by audio‐visual synchrony and linguistic experience. To do so, we tracked eye gaze in 4‐, 6‐, 8‐, 10‐, and 12‐month‐old infants while they were exposed either to desynchronized native or desynchronized non‐native audiovisual fluent speech. Results indicated that, regardless of language, desynchronization disrupted the usual pattern of relative attention to the eyes and mouth found in response to synchronized speech at 10 months but not at any other age. These findings show that audio‐visual synchrony mediates selective attention to a talker's mouth just prior to the emergence of initial language expertise and that it declines in importance once infants become native‐language experts.     

Reduced adaptability,but no fundamental disruption,of norm‐based face coding following early visual deprivation from congenital cataracts

Faces are adaptively coded relative to visual norms that are updated by experience, and this adaptive coding is linked to face recognition ability. Here we investigated whether adaptive coding of faces is disrupted in individuals (adolescents and adults) who experience face recognition difficulties following visual deprivation from congenital cataracts in infancy. We measured adaptive coding using face identity aftereffects, where smaller aftereffects indicate less adaptive updating of face‐coding mechanisms by experience. We also examined whether the aftereffects increase with adaptor identity strength, consistent with norm‐based coding of identity, as in typical populations, or whether they show a different pattern indicating some more fundamental disruption of face‐coding mechanisms. Cataract‐reversal patients showed significantly smaller face identity aftereffects than did controls (Experiments 1 and 2). However, their aftereffects increased significantly with adaptor strength, consistent with norm‐based coding (Experiment 2). Thus we found reduced adaptability but no fundamental disruption of norm‐based face‐coding mechanisms in cataract‐reversal patients. Our results suggest that early visual experience is important for the normal development of adaptive face‐coding mechanisms.     

Mental Health Disparities,Treatment Engagement,and Attrition Among Racial/Ethnic Minorities with Severe Mental Illness: A Review

Mounting evidence indicates that there are mental health disparities in the United States that disadvantage racial/ethnic minorities in medical and mental health settings. Less is known, however, about how these findings apply to a particularly vulnerable population, individuals with severe mental illness (SMI). The aim of this paper is to (1) provide a critical review of the literature on racial/ethnic disparities in mental health care among individuals with SMI; (2) identify factors which may contribute to the observed disparities; and (3) generate recommendations on how best to address these disparities. Specifically, this article provides an in-depth review of sociocultural factors that may contribute to differences in treatment engagement and rates of attrition from treatment among racial/ethnic minorities with SMI who present at medical and mental health facilities. This review is followed by a discussion of specific strategies that may promote engagement in mental health services and therefore reduce racial/ethnic disparities in SMI.     

Recalling what was where when seeing nothing there

So-called “looks-at-nothing” have previously been used to show that recalling what also elicits the recall of where this was. Here, we present evidence from an eye-tracking study which shows that disrupting looks to “there” does not disrupt recalling what was there, nor do (anticipatory) looks to “there” facilitate recalling what was there. Therefore, our results suggest that recalling where does not recall what.     

Protected or Unprotected Sex: The Conceptions and Attitudes of the Youth in Bolgatanga Municipality,Ghana

The youth in Bolgatanga municipality in Ghana have relatively less knowledge of sexual and reproductive health (SRH) compared to the youth in other parts of Ghana. More fundamental knowledge is needed of the factors that influence young people to have protected and unprotected sex in specific social and cultural contexts, in order to protect them from adverse consequences, such as sexually transmitted diseases (STIs), HIV/AIDS and unintended pregnancies. This study therefore analyzed the conceptions and attitudes of the youth toward protected and unprotected sex, and particularly condom use, in Bolgatanga municipality. Semi-structured and focus group interviews were held with 71 young males and females and 17 adults. The results indicated that many of them lack a comprehensive knowledge of STIs, contraceptives and pregnancy, while a group of them had a negative attitude towards contraceptives. Not all parents, schools and organisations provide young people with a comprehensive education about SRH, and some even discourage such education because they believe it would encourage young people to have sex before marriage. In addition, young people also inform each other about SRH issues, sharing stories and personal experiences with their peers. The information they exchange is not always correct, however; sometimes it merely reflects their own personal preferences. The unequal power in the sexual relationships of young people—related to the traditional value system that gives men, but not women, “sexual freedom, both in and outside marriage”—is another determining factor for unprotected sex.     

The effects of aging on the working memory processes of multimodal information

Normal aging is associated with deficits in working memory processes. However, the majority of research has focused on storage or inhibitory processes using unimodal paradigms, without addressing their relationships using different sensory modalities. Hence, we pursued two objectives. First, was to examine the effects of aging on storage and inhibitory processes. Second, was to evaluate aging effects on multisensory integration of visual and auditory stimuli. To this end, young and older participants performed a multimodal task for visual and auditory pairs of stimuli with increasing memory load at encoding and interference during retention. Our results showed an age-related increased vulnerability to interrupting and distracting interference reflecting inhibitory deficits related to the off-line reactivation and on-line suppression of relevant and irrelevant information, respectively. Storage capacity was impaired with increasing task demands in both age groups. Additionally, older adults showed a deficit in multisensory integration, with poorer performance for new visual compared to new auditory information.     

The psychological coping,learning potential and career preferences profiles of operational force military candidates

The aim of this study was to profile the psychological coping, learning potential and career-related interests of 251 candidates for operational force military selection for the South African National Defence Force (SANDF) – 26 of whom were successful in the selection. Data on their sense of meaning, learning potential and career-related interest were gathered using standardised measures supplemented with open-ended responses. The data were analysed to compare the profiles of the successful candidates against those not selected. The selected group showed significantly higher mean scores on meaningfulness and learning potential, and lower scores for career-related interest in law and medicine. Findings suggest that psychological coping, learning potential and career-related preference information can be used to refine the selection of operational force military candidates.
