When someone encounters an explanation perceived as weak, this may lead to a feeling of deprivation or tension that can be resolved by engaging in additional learning. This study examined to what extent children respond to weak explanations by seeking additional learning opportunities. Seven‐ to ten‐year‐olds (N = 81) explored questions and explanations (circular or mechanistic) about 12 animals using a novel Android tablet application. After rating the quality of an initial explanation, children could request and receive additional information or return to the main menu to choose a new animal to explore. Consistent with past research, there were both developmental and IQ‐related differences in how children evaluated explanation quality. But across development, children were more likely to request additional information in response to circular explanations than mechanistic explanations. Importantly, children were also more likely to request additional information in direct response to explanations that they themselves had assigned low ratings, regardless of explanation type. In addition, there was significant variability in both children's explanation evaluation and their exploration, suggesting important directions for future research. The findings support the deprivation theory of curiosity and offer implications for education.  相似文献

The detrimental effects of parental break-up on children's mental health are well-documented. However, research has also shown that children living in joint physical custody (JPC) arrangements often fare better than children living in sole physical custody (SPC) arrangements. Thus, the question arises: What are the differences between JPC and SPC that account for those results? Drawing on data from the Family Models in Germany (FAMOD) study conducted in 2019, structural equation models (SEM) were estimated to deduct the mediating role of coparenting support in children's mental health in 465 JPC and 652 SPC families with children aged 2–14. The findings suggest that the better mental health observed among children in JPC families than among children in SPC families was fully mediated by coparenting support. However, this held true only for internalizing and externalizing behavior, but not for prosocial behavior as no differences between JPC and SPC were found for this dimension. The findings affirm the importance of supportive coparenting for children's well-being after family dissolution in both SPC and JPC arrangements. After breaking up, parents should be supported in their parental engagement through coparenting counseling or psychoeducation classes.  相似文献

Numbsense is a phenomenon, wherein patients can correctly respond to somatosensory stimuli at a higher rate than expected by chance, but cannot perceive the same stimuli consciously. Previously, numbsense has been reported in tactile localization of stimuli on the patient’s own body. Here, we describe a patient with numbsense that involved touched objects. The patient could not recognize the majority of somatosensory stimuli after left parietal infarction, but could correctly select shape, texture, and object stimuli more frequently than expected by chance.  相似文献

We examined factors that account for quality of life among parents of clinically referred children. Families (N = 201) of children (ages 3-14) referred for oppositional, aggressive, and antisocial behavior participated. Parent and family contextual factors and child psychosocial functioning (symptoms and impairment) were predicted to influence parents' quality of life. As predicted, socioeconomic disadvantage, parent stress and psychopathology, poor interpersonal relations, and limited social support were related to lower levels of quality of life. Once these factors were controlled, child psychosocial functioning also contributed positively to quality of life. Further research on quality of life in the family can have important implications for understanding the context of both child and parent functioning.  相似文献

This paper presents a structural model of the determinants of harsh parenting among Mexican mothers. One hundred five mothers (46 from the community; 59 referred to agencies for child maltreatment) were recruited from Sonora (Northern) Mexico and interviewed. In this model the use of physical punishment was explained by (1) authoritarian parenting style (mothers' beliefs concerning the effective use of physical punishment and mothers' lack of disciplinary skills) and (2) family dysfunction (a latent variable constructed from reports of interspousal violence and the parents' use of alcohol and drugs). In addition, the indirect effects of demographic and historical variables on harsh parenting was included. The findings show that the most important factor influencing the use of physical punishment in these families was authoritarian parenting style, exerting a significant direct effect on the mothers' reports of their use of harsh punishment. Family dysfunction had an indirect effect through parenting style. Some sociodemographic variables also indirectly influenced the use of beliefs maternal punishment It is concluded that cultural beliefs play a major role in parenting within the framework of Mexican family relations.  相似文献

Debate about infant care tends to focus on still unresolved questions about whether or not day care is harmful, while research studies often confine care options to an unrealistic axis of choice between group care and mother care. Research that delineates constituents of day care quality in relation to measurable outcomes for different groups of children is urgently needed and should be based on a broader view of infant care options. A postal opinion survey sought the confidential views of members of an international organization of infant mental health professionals as to the kinds of care they considered likely to be best for infants from birth to 36 months, assuming that all types of care were of equally high quality and availability. Surprisingly lengthy periods of care by mothers were consistently endorsed; fathers were almost entirely disregarded as principal or joint caregivers; all forms of family care were endorsed over all forms of purchased care, but all forms of individual care were preferred to full-day group care for all age groups and to half-day group care up to the age of 2. The patterns of care judged by these respondents as likely to be best for infants are very different from those which most infants experience now, and from those which policy- and opinion-makers, practitioners and parents aspire, publicly at least, to provide for infants in the future. ©1997 John Wiley & Sons, Ltd.  相似文献

This review integrates and critically evaluates what is known about family characteristics associated with childhood Attention-Deficit/Hyperactivity Disorder (ADHD). Evidence suggests that the presence of ADHD in children is associated to varying degrees with disturbances in family and marital functioning, disrupted parent–child relationships, specific patterns of parental cognitions about child behavior and reduced parenting self-efficacy, and increased levels of parenting stress and parental psychopathology, particularly when ADHD is comorbid with conduct problems. However, the review reveals that little is known about the developmental mechanisms that underlie these associations, or the pathways through which child and family characteristics transact to exert their influences over time. In addition, the influence of factors such as gender, culture, and ADHD subtype on the association between ADHD and family factors remains largely unknown. We conclude with recommendations regarding the necessity for research that will inform a developmental psychopathology perspective of ADHD.  相似文献

Novelty seeking and sensation seeking are constructs useful in predicting human risk-taking behaviors. This predictive relation purportedly reflects some rewarding aspect of experiencing novelty. Research has confirmed this assumption. Rats display an increase in preference for an environment that has been differentially paired with novel stimuli. The physiological mechanisms mediating this rewarding effect of novelty involve the neurotransmitter dopamine, whereas those controlling novelty seeking do not. The mechanisms involved in drug seeking and reward show parallel dissociations. This concordance between novelty and drug-abuse research suggests that novelty and drug stimuli may interact in biologically and behaviorally meaningful ways. Indeed, preliminary research examining cocaine and novelty and published work with amphetamines support this suggestion. There is clear need for further systematic research on novelty reward and related processes at all levels of analysis: genetic, biological, behavioral, and social.  相似文献

The present study assessed how attorneys questioned children in cases of child sexual abuse in the United States tried between 2005 and 2015. Trial testimonies (N = 134) of 5- to 17-year-olds (M = 12 years old) were coded for the linguistic form of attorneys' questions and children's subsequent responses. Three fourths of all questions were closed ended. Both declarative (statement question; e.g., “And he hit you?”; 21% of questions) and indirect yes/no questions (beginning with an indirect speech act; e.g., “Do you remember X?”; 11% of questions) were common, and produced potentially problematic responses, in comparison with forced-choice and yes/no questions. Declarative questions elicited the highest rates of unelaborative responses whereas indirect yes/no questions elicited the highest rate of nonsubstantive responses. The findings highlight the importance for researchers to better assess children's responses to declarative questions and for prosecuting attorneys to cautiously use declarative and indirect yes/no questions when questioning children.  相似文献
