Multimodal access to verbal name codes

Congruent information conveyed over different sensory modalities often facilitates a variety of cognitive processes, including speech perception (Sumby & Pollack, 1954). Since auditory processing is substantially faster than visual processing, auditory-visual integration can occur over a surprisingly wide temporal window (Stein, 1998). We investigated the processing architecture mediating the integration of acoustic digit names with corresponding symbolic visual forms. The digits "1" or "2" were presented in auditory, visual, or bimodal format at several stimulus onset asynchronies (SOAs; 0, 75, 150, and 225 msec). The reaction times (RTs) for echoing unimodal auditory stimuli were approximately 100 msec faster than the RTs for naming their visual forms. Correspondingly, bimodal facilitation violated race model predictions, but only at SOA values greater than 75 msec. These results indicate that the acoustic and visual information are pooled prior to verbal response programming. However, full expression of this bimodal summation is dependent on the central coincidence of the visual and auditory inputs. These results are considered in the context of studies demonstrating multimodal activation of regions involved in speech production.     

The social psychological power of photography: can the image‐freezing machine make something of nothing?

Sontag ( 1990 ) proposed that taking a photograph imparts social significance to the moment being captured. Two experiments were conducted to examine how the experience of being photographed affects the social relations of those who are photographed. In Experiment 1 (N=92), unacquainted members of dyads who were photographed together and then saw the resulting image displayed greater social self‐categorization and greater affinity for each other than did dyads who were not photographed (p<0.05). In Experiment 2 (N=282), pairs of photographed strangers also displayed greater social self‐categorization and mutual affinity than pairs of nonphotographed strangers (p<0.05). This effect occurred whether pair members were explicitly framed together in photographs or not. This result was unaffected by whether the photographed strangers were shown or were not shown their photograph. Merely opening and closing the shutter of a camera was sufficient for the development of a photo‐bonding effect. Results are discussed in terms of how the experience of being photographed can affect interpersonal perception and relationship formation. The significance of being photographed (Milgram, 1977 ; Sontag, 1990 ) apparently is so strong that it promotes social self‐categorization (Turner, Hogg, Oakes, Reicher, & Wetherell, 1987 ) both when people are photographed simultaneously and sequentially.

Emotional,Cognitive, Behavioral,and Temperament Characteristics of High-Empathy Children

Recent research has suggested that individual differences in young children's capacity for empathy and altruism has heritable components and may be related to early temperament. These individual differences, like other human capacities such as intelligence, may be distributed normally. Thus, high-empathy children may exhibit cognitive, emotional, and behavioral precocity in empathic and altruistic responding, and begin expressing these capacities early in life. Twenty-seven 2- to 8-year-old (M = 53 months), primarily Euro-American high-empathy children (10 male) were identified by childcare center staff. Ethnographically oriented interviews of their mothers provided detailed accounts of the children's empathic and altruistic responding in everyday interactions at home and school. As a group, the children were described as emotionally positive, especially sociable individuals whose empathic and altruistic responses were highly spontaneous, occurred more frequently, and differed from peers in depth, intensity, and persistence. Parallels were drawn between these capacities and temperamental dispositions for self-regulation and emotional reactivity. Limitations of the methodology and directions of future research are discussed.     

Time Costs for Genetic Counseling in Preconception Carrier Screening with Genome Sequencing

Advances in technology and the promise of personalized health care are driving greater use of genome sequencing (GS) for a variety of clinical scenarios. As health systems consider adopting GS, they need to understand the impact of GS on the organization and cost of care. While research has documented a dramatic decrease in the cost of sequencing and interpreting GS, few studies have examined how GS impacts genetic counseling workloads. This study examined the time needed to provide genetic counseling for GS in the context of preconception carrier screening. Genetic counselors prospectively reported on the time spent in the results disclosure process with 107 study participants who were part of the NextGen study. We found that the median time for results disclosure was 64 min (ranged from 5 to 229 min). Preparation work was the most time-consuming activity. Qualitative data from journal entries, debrief interviews with genetic counselors, and detailed case conference notes provided information on factors influencing time for results disclosure and implications for practice. Results suggest that expanded carrier screening could require significant increases in genetic counseling time, unless we are able to generate new resources to reduce preparation work or develop other strategies such as the creation of new models to deliver this type of service.     

Relationship of Mindfulness to Distress and Cortisol Response in Adolescent Girls At-Risk for Type 2 Diabetes

Altered stress response theoretically contributes to the etiology of cardiometabolic disease. Mindfulness may be a protective buffer against the effects of stress on health outcomes by altering how individuals evaluate and respond to stress. We engaged adolescent girls at risk for developing Type 2 diabetes in a cold-pressor test in order to determine the relationship of dispositional mindfulness to cortisol response and subjective stress, including perceived pain and unpleasantness during the stressor, and negative affect following the stressor. We also evaluated mindfulness as a moderator of psychological distress (depressive/anxiety symptoms) and stress response. Participants were 119 girls age 12–17 years with overweight/obesity, family history of diabetes, and mild-to-moderate depressive symptoms. Greater mindfulness was associated with less perceived pain and negative affect, but was unrelated to cortisol response to the stressor. Regardless of mindfulness, greater depressive/anxiety symptoms related to a more blunted cortisol response. Mindfulness might promote better distress tolerance in adolescents at risk for diabetes by altering how youth perceive and relate to acute stress, rather than through altering the physiological stress response. At all levels of mindfulness, depressive/anxiety symptoms relate to greater blunting of cortisol response. Findings contribute to emerging literature on the role of mindfulness in promoting the mental and physical health and well-being of individuals at risk for Type 2 diabetes.
