The frequency of positive parent–child interactions is associated with youth adjustment. Yet, little is known about daily parent–child interactions and how day-to-day consistency in positive parent–child interactions may be linked to youth well-being. Using a daily diary approach, this study added to this literature to investigate whether and how day-to-day consistency in positive parent–child interactions was linked to youth depressive symptoms, risky behavior, and physical health. Participants were youth whose parents were employed in the IT division of a Fortune 500 company (N?=?129, youth’s mean age?=?13.39, 55?% female), who participated in an 8?day daily diary study. Analyses revealed that, controlling for cross-day mean levels of positive parent–child interactions, older (but not younger) adolescents who experienced more consistency in positive interactions with parents had fewer depressive and physical health symptoms (e.g., colds, flu). The discussion focuses on the utility of daily diary methods for assessing the correlates of consistency in parenting, possible processes underlying these associations, and intervention implications.  相似文献

Beyond a hedonic model of the good life—approach pleasure and avoid pain—evidence is accumulating across species that well-being depends on potentially painful goal pursuit processes, like effort, engagement, and discovery. We hypothesized that daily challenges may provide a unique opportunity to fulfill such processes and that challenges would be more relevant within the promotion (gain-focused) than prevention (nonloss-focused) motivational system. Accordingly, we predicted that: (1) individuals who tend to be successful versus unsuccessful in achieving promotion-type goals would be better at managing daily challenges; and (2) challenge dysregulation would undermine promotion-related well-being (depressive symptoms) more than prevention-related well-being (anxiety symptoms). Across three studies, we find evidence in support of these hypotheses. Notably, as we find consistent evidence that too many and too few challenges may be damaging to mental health, we conclude that effective challenge regulation—not minimization—is likely to be a necessary component of optimal well-being.  相似文献

To investigate the format of mental images and the penetrability of mental imagery performance to top-down influences in the form of gravity information, children (4-, 6-, 8- and 10-year-olds) and adults (N = 112) performed mental rotation tasks. A linear increase in response time with rotation angle emerged at 6-years, suggesting that spatial properties are represented in children’s mental images. Moreover, 6-, 8-, and 10-year-olds, but not 4-year-olds or adults, took longer to respond to rotated stimuli pairs when gravity information was incongruent with the direction of rotation rather than congruent. Overall, findings suggest that in contrast to adults’, 6- to 10-year-olds’ mental rotation performance was penetrated by top-down information. This research (a) provides insight into the format of young children’s mental images and (b) shows that children’s mental rotation performance is penetrable by top-down influences.  相似文献

In this paper it is argued that the “cognitive revolution” in psychology is not best represented either as a Kuhnian “paradigm shift,” or as a movement from an instrumentalist to a realist conception of psychological theory, or as a continuous evolution out of more “liberalized” forms of behaviorism, or as a return to the form of “structuralist” psychology practiced by Wundt and Titchener. It is suggested that the move from behaviorism to cognitivism is best represented in terms of the replacement of (operationally defined) “intervening variables” by genuine “hypothetical constructs” possessing cognitive “surplus meaning,” and that the “cognitive revolution” of the 1950s continued a cognitive tradition that can be traced back to the 1920s. © 1999 John Wiley & Sons, Inc.  相似文献

What aspects of infants’ prelinguistic communication are most valuable for learning to speak, and why? We test whether early vocalizations and gestures drive the transition to word use because, in addition to indicating motoric readiness, they (a) are early instances of intentional communication and (b) elicit verbal responses from caregivers. In study 1, 11 month olds (N = 134) were observed to coordinate vocalizations and gestures with gaze to their caregiver's face at above chance rates, indicating that they are plausibly intentionally communicative. Study 2 tested whether those infant communicative acts that were gaze‐coordinated best predicted later expressive vocabulary. We report a novel procedure for predicting vocabulary via multi‐model inference over a comprehensive set of infant behaviours produced at 11 and 12 months (n = 58). This makes it possible to establish the relative predictive value of different behaviours that are hierarchically organized by level of granularity. Gaze‐coordinated vocalizations were the most valuable predictors of expressive vocabulary size up to 24 months. Study 3 established that caregivers were more likely to respond to gaze‐coordinated behaviours. Moreover, the dyadic combination of infant gaze‐coordinated vocalization and caregiver response was by far the best predictor of later vocabulary size. We conclude that practice with prelinguistic intentional communication facilitates the leap to symbol use. Learning is optimized when caregivers respond to intentional vocalizations with appropriate language.  相似文献

Low socioeconomic status (SES) is associated with greater risk for symptoms of attention‐deficit/hyperactivity disorder (ADHD). One mechanism through which SES may confer risk for ADHD is by influencing brain structure. Alterations to cortical thickness, surface area and subcortical volume have been associated with low SES and with the presence of ADHD across multiple studies. The current study examined whether cortical thickness, surface area or subcortical volume mediate the associations between SES and ADHD in youth 3–21 years old (N = 874) from the Pediatric Imaging, Neurocognition and Genetics Study. Freesurfer was used to estimate cortical thickness, surface area and subcortical volume from structural magnetic resonance imaging. Parents reported on demographics, family SES, ADHD diagnoses and the presence of child attention problems. Statistical mediation was assessed using a bootstrap resampling procedure. Controlling for parental ADHD, child age, gender, birth weight and scanner, children in low SES families were more likely to be in the ADHD group. Consistent with previous reports in this sample, low SES was associated with reduced surface area across the frontal lobe and reduced subcortical volume in the amygdala, cerebellum, hippocampus and basal ganglia. Of these regions, a significant indirect effect of SES on ADHD status through subcortical volume was observed for the left cerebellum (95% confidence interval: 0.004, 0.022), the right cerebellum (95% confidence interval: 0.006, 0.025), and the right caudate (95% confidence interval: 0.002, 0.022). Environmentally mediated changes in the cerebellum and the caudate may be neurodevelopmental mechanisms explaining elevated risk of ADHD in children in low SES families.  相似文献

Exposure to childhood adversity is common and associated with a host of negative developmental outcomes. The most common approach used to examine the consequences of adversity exposure is a cumulative risk model. Recently, we have proposed a novel approach, the dimensional model of adversity and psychopathology (DMAP), where different dimensions of adversity are hypothesized to impact health and well‐being through different pathways. We expect deprivation to primarily disrupt cognitive processing, whereas we expect threat to primarily alter emotional reactivity and automatic regulation. Recent hypothesis‐driven approaches provide support for these differential associations of deprivation and threat on developmental outcomes. However, it is not clear whether these patterns would emerge using data‐driven approaches. Here we use a network analytic approach to identify clusters of related adversity exposures and outcomes in an initial study (Study 1: N = 277 adolescents aged 16–17 years; 55.1% female) and a replication (Study 2: N = 262 children aged 8–16 years; 45.4% female). We statistically compare our observed clusters with our hypothesized DMAP model and a clustering we hypothesize would be the result of a cumulative stress model. In both samples we observed a network structure consistent with the DMAP model and statistically different than the hypothesized cumulative stress model. Future work seeking to identify in the pathways through which adversity impacts development should consider multiple dimensions of adversity.  相似文献
