The present investigation examined the functioning of inhibitory mechanisms in younger and older bilinguals using a bilingual version of the Stroop test. The study predicted different patterns of age related decline in inhibitory mechanisms (inter- and intralingual interference) in bilinguals depending on their level of proficiency. Consistent with expectations, older bilinguals were slower when they responded in their non-dominant language. Furthermore, older unbalanced bilinguals showed greater interlingual interference when they responded with their second language to visual stimuli written in their dominant language. Balanced bilinguals showed equivalent interference effects between all conditions. These findings suggest that manipulating two languages may enhance the efficiency of inhibitory mechanisms. 相似文献

Prior research linking occupational sex composition (the proportion of women in an occupation) to housework has yielded conflicting results and relies exclusively on cross-sectional data. The present article extends scholarship on the gendered division of household labor by using longitudinal data from the Panel Study of Income Dynamics (PSID) 1981–2013 to assess how changes in occupational sex composition alter heterosexual married couples’ housework performance over time. I find that either spouse’s gender-atypical employment (e.g., husband’s employment in a predominately female job) is associated with gender-atypical housework performance by both spouses (e.g., higher housework hours for the husband and fewer hours for the wife). The association of women’s occupational sex composition with housework is driven by changes in individual women’s occupations and both spouses’ housework over time. In contrast, the association of men’s occupational sex composition with housework is driven by differences between different couples, not by within-couple change over time. Thus, fundamentally different causal mechanisms link women’s and men’s occupational sex composition to couples’ housework performance, and only for women are longitudinal changes in occupational sex composition associated with changes in housework. These findings have important implications for understanding occupation and housework as domains of gender performance. 相似文献

Dogs' capacity to 'catch' human yawns has recently attracted the attention of researchers in the field of animal cognition. Following recent studies suggesting that contagion yawning in humans, and some other primates, is empathy-related, some authors have considered the possibility that the same mechanism may underlie contagious yawning in dogs. To date, however, no positive evidence has been found, and more parsimonious hypotheses have been put forward. The present study explored the 'contagion-only' hypothesis by testing whether the mere sound of a human yawn can be sufficient to elicit yawning in dogs, in a way that is unaffected by social-emotional factors. Unexpectedly, results showed an interesting interplay between contagion and social effects. Not only were dogs found to catch human yawns, but they were also found to yawn more at familiar than unfamiliar yawns. Although not allowing for conclusive inferences about the mechanisms underlying contagious yawning in dogs, this study provides first data that renders plausible empathy-based, emotionally connected, contagious yawning in these animals. 相似文献

Most studies regarding the role of teacher-child relationships for children's early school adjustment use only teacher ratings of relationship quality. The current study examines (a) the agreement between teacher and observer ratings, (b) whether similar patterns of relations with behavioral engagement are obtained across informants, and (c) which informant matters the most in the prediction of engagement. Teacher and observer ratings of teacher-child closeness, conflict, and dependency were gathered for a sample of 148 kindergartners and their teachers at three measurement occasions. Teacher and observer reports converged to a moderate degree but only when considering multiple occasions and ruling out occasion-specific variance. Although some relations with behavioral engagement were similar, only teacher ratings had unique, added value in this prediction. 相似文献

Research on early signs of autism in social interactions often focuses on infants’ motor behaviors; few studies have focused on speech characteristics. This study examines infant‐directed speech of mothers of infants later diagnosed with autism (LDA; n = 12) or of typically developing infants (TD; n = 11) as well as infants’ productions (13 LDA, 13 TD). Since LDA infants appear to behave differently in the first months of life, it can affect the functioning of dyadic interactions, especially the first vocal productions, sensitive to expressiveness and emotions sharing. We assumed that in the first 6 months of life, prosodic characteristics (mean duration, mean pitch, and intonative contour types) will be different in dyads with autism. We extracted infants’ and mothers’ vocal productions from family home movies and analyzed the mean duration and pitch as well as the pitch contours in interactive episodes. Results show that mothers of LDA infants use relatively shorter productions as compared to mothers talking to TD infants. LDA infants’ productions are not different in duration or pitch, but they use less complex modulated productions (i.e., those with more than two melodic modulations) than do TD. Further studies should focus on developmental profiles in the first year, analyzing prosody monthly. 相似文献

We assessed whether certain life events contributed to the communication about cancer risk within families who have undergone BRCA1/2 testing. We also explored what type of resources participants would have valued to help in supporting family communication about genetic information. Two hundred and forty-six individuals (218 women, 28 men) who received a BRCA1/2 genetic test result 3 to 10 years earlier (mean of 6.4 years) participated in a telephone interview. Participants were asked about the occurrence of a number of life events (cancer diagnosis, death, uptake of prophylactic surgery, and providing care to a family member with cancer) in their family since their BRCA1/2 test result disclosure and, for each occurrence, whether it fostered family communication about cancer risk. A total of 182 participants (74 %) reported that they or one of their relatives received a cancer diagnosis, 176 (72 %) reported that someone died in their family, and 73 (30 %) stated that they or one of their relatives undertook a prophylactic surgery. During this period, 109 participants (44 %) also provided care for a family member who had cancer. Among participants who reported these life events, family communication was fostered by these events in proportions varying from 50 % (death) to 69 % (cancer diagnosis). Our results indicate that life events may contribute to family communication about cancer risk. Further research is needed to determine whether these events provide a “window of opportunity” to reach family members, address their needs and concerns about cancer, update family cancer history, and introduce genetic counseling and risk assessment. 相似文献
