The attentional blink (AB) is thought to help the visual system parse and categorize rapidly changing information by segmenting it into temporal chunks, and is elicited using Rapid Serial Visual Presentation. It is reflected in a decrease in accuracy at detecting the second of two targets presented within 200–500 ms of the first, and its development appears to be protracted on tasks that require set‐shifting. Here, younger (M = 8.5 years) and older (M = 12.8 years) children and adults (M = 19.13 years) completed a simple AB task with no set‐shift requirement in which participants detected two letters in a stream of numbers presented at a rate of 135 ms/item. In addition to assessing the developmental course of the AB on this simple task, we also assessed temporal order errors, or swaps. The AB and its associated characteristics are present in both groups but developmental differences were noted in the depth of the AB, and the presence or absence of lag‐1 sparing. These developmental changes were explained by changes in a single parameter, inhibition, using the eTST model, which suggests that the AB is an adaptive function of the visual system. 相似文献

Are U.S. consumers using MyPlate and restaurant menu labels and does their use equate with dietary and exercise behavior?

The U.S. government provided a website, entitled MyPlate, and required menu labels to state calories to help the population make healthy dietary and exercise choices. The purpose of this study is to assess the awareness and use of nutrition information provided by MyPlate and by restaurant menu labels with dietary and exercise behavior for U.S. adults considering race/ethnicity and gender. This study uses data from the National Health and Nutrition Examination Survey 2013–2014 for adults, aged 20 years and older, from 3 racial/ethnic groups N = 4924: 1,275 Hispanics, 1,177 non‐Hispanic Blacks (NHB); 2,472 non‐Hispanic Whites to assess awareness and who reported seeing nutrition information at fast‐food/pizza places and waitstaff restaurants and answered affirmatively to hearing about MyPlate (N = 749). Dietary behaviors for controlling or losing weight, reducing fat, and increasing exercise was significantly higher for those who tried MyPlate as compared with those who stated they did not try MyPlate. Over half the individuals who reported that they tried MyPlate stated that they would often use nutrition information for fast‐food/pizza places and waitstaff restaurants as compared with less than one‐third of individuals who declared that they have not tried MyPlate. Males, Hispanics, NHB, individuals with a lower education level, current smokers, and older adults had higher percent of not hearing about MyPlate. NHB, males, and older adults had a lower percent of using menu nutrition information. Increasing use of MyPlate and menu calorie labeling may serve to encourage vulnerable groups to make healthy dietary and exercise choices. 相似文献

Recent interest has emerged in understanding the neural mechanisms by which deficits in emotion regulation (ER) early in development may relate to later depression. Corticolimbic alterations reported in emotion dysregulation and depression may be one possible link. We examined the relationships between emotion dysregulation in school age, corticolimbic resting-state functional connectivity (rs-FC) in preadolescence, and depressive symptoms in adolescence. Participants were 143 children from a longitudinal preschool onset depression study who completed the Children Sadness Management Scale (CSMS; measuring ER), Child Depression Inventory (CDI-C; measuring depressive symptoms), and two resting-state MRI scans. Rs-FC between four primary regions of interest (ROIs; bilateral dorsolateral prefrontal cortex [dlPFC] and amygdala) and six target ROIs thought to contribute to ER were examined. Findings showed that ER in school age did not predict depressive symptoms in adolescence, but did predict preadolescent increases in dlPFC-insula and dlPFC-ventromedial PFC rs-FC across diagnosis, as well as increased dlPFC-dorsal anterior cingulate cortex (dACC) rs-FC in children with a history of depression. Of these profiles, only dlPFC-dACC rs-FC in preadolescence predicted depressive symptoms in adolescence. However, dlPFC-dACC connectivity did not mediate the relationship between ER in school age and depressive symptoms in adolescence. Despite the absence of a direct relationship between ER and depressive symptoms and no significant rs-FC mediation, the rs-FC profiles predicted by ER are consistent with the hypothesis that emotion dysregulation is associated with abnormalities in top-down control functions. The extent to which these relationships might confer greater risk for later depression, however, remains unclear. 相似文献

The purpose of the current study was to examine the relative contributions of weight status, race/ethnicity, sex, and age on body dissatisfaction in a large group of diverse children. Participants were 4th–6th graders (N = 1212) in ten inner-city schools who participated in an obesity prevention study previously published. Children completed the body dissatisfaction subscale of the Eating Disorder Inventory-2 (EDI-2), and weight status was assessed by measured weights and heights. Multiple regression analyses were conducted. Relative weight status was the strongest predictor of body dissatisfaction, followed by race/ethnicity, and sex. Body dissatisfaction was greatest in obese, Asian, and female children. Overall, results indicated that children's body dissatisfaction varies based on relative weight status, as well as race/ethnicity and sex among urban children. Results highlight the strong need for additional research so that more definitive conclusions may be drawn regarding the development of body image among diverse groups of children. 相似文献

With a sample of Italians selected from 71 Italian counties (N = 1,868), we performed two multilevel analyses aimed at predicting the perceived risk of crime at local (i.e., in the participants' county of residence) and at societal (i.e., in the context of Italian society) levels. A significant proportion of the variation in local risk perception was at the county level. The following individual variables predicted higher levels of this variable: indirect victimization, the perception of social and physical disorder, being a woman, being poorly educated, and being an older person. Among the ecological predictors, the crime rate and unemployment rate predicted higher levels of local crime risk perception, while the immigrant rate did not. Perceived risk of crime at the societal level did not show significant variation at the county level. Education, being a man, trusting people, and adhesion to post‐materialistic values predicted lower levels of societal crime risk perception, while number of sons/daughters and exposure to television news increased it. The limitations and possible development of this study are discussed. 相似文献

The effects of communal motivation on reactions to relationship partners' expressed anger were examined. In Study 1, married couples reported on the communal strength of their marriage, their expressions of anger to their spouse, and relationship satisfaction. In Study 2, college students reported on the communal strength of their best friendships, those friends' expressions of anger, and their evaluations of and provision of support to those friends. In Study 3, communal motivation toward a stranger who expressed mild anger was manipulated and evaluation of that stranger was measured. In all three studies, low communal motivation was associated with more negative evaluations of angry partners, lower relationship satisfaction, and, in Study 2, lower support provision. In contrast, when communal motivation was high, these decreases either did not occur (Studies 1 and 3) or were diminished (Study 2), and in Study 2, partners' anger was associated with increased provision of social support. 相似文献

Infant sitting postural sway provides a window into motor development at an early age. The approximate entropy, a measure of randomness, in the postural sway was used to assess developmental delay, as occurs in cerebral palsy. Parameters used for the calculation of approximate entropy were investigated, and approximate entropy of postural sway in early sitting was found to be lower for infants with developmental delay in the anterior-posterior axis, but not in the medial-lateral axis. Spectral analysis showed higher frequency features in the postural sway of early sitting of infants with typical development, suggesting a faster control mechanism is active in infants with typical development as compared to infants with delayed development, perhaps activated by near-fall events. 相似文献
