In human infants, the ability to share attention with others is facilitated by increases in attentional selectivity and focus. Differences in early attention have been associated with socio‐cognitive outcomes including language, yet the social mechanisms of attention organization in early infancy have only recently been considered. Here, we examined how social coordination between 5‐month‐old infants and caregivers relate to differences in infant attention, including looking preferences, span, and reactivity to caregivers’ social cues. Using a naturalistic play paradigm, we found that 5‐month‐olds who received a high ratio of sensitive (jointly focused) contingent responses showed strong preferences for objects with which their caregivers were manually engaged. In contrast, infants whose caregivers exhibited high ratios of redirection (attempts to shift focus) showed no preferences for caregivers’ held objects. Such differences have implications for recent models of cognitive development, which rely on early looking preferences for adults’ manually engaged objects as a pathway toward joint attention and word learning. Further, sensitivity and redirectiveness predicted infant attention even in reaction to caregiver responses that were non‐referential (neither sensitive nor redirective). In response to non‐referentials, infants of highly sensitive caregivers oriented less frequently than infants of highly redirective caregivers, who showed increased distractibility. Our results suggest that specific dyadic exchanges predict infant attention differences toward broader social cues, which may have consequences for social‐cognitive outcomes. 相似文献

Objective: Unwanted consensual sex (UCS)—freely consenting to sex that is neither wanted nor desired—is largely excluded from campus programming and the literature on sexual behavior. The present study expands on previous research to examine the relation between childhood victimization experiences and UCS.
Methods: Data were gathered using an online survey of college students.
Results: In the past year, 43% percent of 587 college students who engaged in sexual activity also engaged in UCS at least once. Childhood victimization was modestly related to frequency of UCS. The relation between childhood victimization and UCS was mediated by disconnection/rejection schemas (e.g., beliefs that one’s needs will not be met by others).
Conclusions: Results suggest that altering cognitive schemas through evidence-based psychotherapy may interrupt the relation between childhood victimization and engagement in UCS. 相似文献

Acceptable reliability of normalisation contractions in electromyography (EMG) is paramount for testing conducted over a number of days or if normal laboratory strength testing equipment is unavailable. This study examined the reliability of maximal voluntary isometric contractions (MVIC) and sub-maximal (60%) isometric contractions for use in neck muscle EMG studies. Surface EMG was recorded bilaterally from eight sites around the neck at C4/5 level from five healthy male subjects. Subjects performed MVIC and sub-maximal normalisation contractions using an isokinetic dynamometer (ID) and a portable cable dynamometer with attached strain gauge (PCD) in addition to a MVIC against a manual resistance (MR). Subjects were tested in flexion, extension, left and right lateral bending and were retested by the same tester within a two-week period. Intra class correlation co-efficients (ICC) were calculated for each testing method and contraction direction and a mean ICC was calculated across all contraction directions. All normalisation methods produced excellent within-day reliability (mean ICC >0.80) but only the MVICs using the ID and PCD had acceptable reliability when assessed between-days. This study confirmed the validity of using MVICs elicited using the ID and PCD as reliable reference contractions for the normalisation of neck EMG. 相似文献

There is a glaring lack of data to inform culturally appropriate HIV prevention interventions targeting environments such as bathhouses where men who have sex with men (MSM) practice sexual risk behaviors. This study compares sexual behavioral patterns across two bathhouse sites in order to identify important themes to address when tailoring HIV prevention interventions to bathhouse environments. We analyzed semi-structured interviews with workers and patrons at two bathhouses to explore similarities and differences. A coding scheme was established and data were organized according to conceptual themes. We found that differences between the two sites emerged in six key areas: bathhouse clientele, attraction to particular sites, sexual practices and condom use, communication about sex and HIV status, bathhouse rules, and substance use. Implications for HIV prevention intervention policy are discussed. 相似文献

The goals of this study were to test the relationship between dating violence victimization (i.e., verbal, emotional, and physical abuse) and psychological well-being (i.e., depressive symptomatology, self-esteem, and body image) among 522 African American girls, and to determine whether social support acted as a buffer of negative effects (moderator) or as an intervening factor (mediator) in the relationship between dating violence victimization and psychological well-being. Results from structural equation modeling indicated that dating violence victimization was associated with negative psychological outcomes. Although social support did not moderate this relationship, it served as a mediator of the relationship between dating violence victimization and psychological well-being. Dating violence programs for African American girls should consider how to incorporate family, church, and other networks in the community to foster support, and allow adolescent girls to discuss their abusive experiences in a nonblaming environment. If programs are able to buoy girls who experience dating violence, then they may be able to ameliorate the associated negative psychological sequelae. 相似文献
