The co-occurrence of internalizing and externalizing disorders suggests that they may have common underlying vulnerability factors. Research has shown that negative affect is moderately positively correlated with both internalizing and externalizing disorders in children. The present study is the first to provide an examination of negative affect in relation to a wide spectrum of childhood internalizing and externalizing problems using a biometric model. This study extends prior findings of more narrowly focused associations by using a factor approach including multiple disorders. The sample for this study included families of 691 same-sex 7- to 13-year old twin pairs. A multifactorial independent pathway model was used to examine the genetic and environmental influences underlying the covariation of parent-reported negative affect, internalizing symptoms, and externalizing symptoms. Results of the current study suggest that negative affect shares genetic and environmental influences with both internalizing and externalizing disorders in childhood. These common influences may partially explain their comorbidity. Understanding that negative affect is at least one contributor to the covariation among these disorders may highlight avenues for early risk assessment, intervention, and perhaps prevention. 相似文献
Abstract Envy and resentment are generally thought to be unpleasant and unethical emotions which ought to be condemned. I argue that both envy and resentment, in some important forms, are moral emotions connected with concern for justice, understood in terms of desert and entitlement. They enable us to recognise injustice, work as a spur to acting against it and connect us to others. Thus, we should accept these emotions as part of the ethical life. 相似文献
Using date from a pilot study into pupil work experience pre-16, it is argued that work experience has expanded rapidly on the basis of little evidence and many claims about what it can achieve. As experience-based learning, it relies heavily upon debriefing to maximise its learning potential. If work experience is to be more than a work transition exercise, then debriefing becomes central to its success. Although difficult to accomplish and surrounded by muddled definitions, this approach deserves greater attention in view of the contribution it can make to pupils' ability to manage their own learning and the foundation it can provide for continuous learning throughout life. 相似文献
As a test of Wagner's (1981) theory of habituation, three experiments examined the effects of stimulus preexposure on electrodermal responding to the absence of a stimulus and on omission-produced dishabituation. The general procedure for all experiments consisted of a preexposure phase in which one stimulus (S1) was presented 20 times, followed by a pairing phase in which S1 was followed by a second event, S2. After a number of S1-S2 pairings, S2 was omitted for one trial and was then represented following S1 on the next trial. Electrodermal activity was measured in all experiments, and in Experiments 2 and 3, a measure of expectancy of S2 in the presence of S1 was also obtained to provide a putative index of S2 priming by S1. Experiments 1 (N=48) and 2 (N=72) employed 15 S1-S2 pairings prior to S2 omission. Significant omission responding and dishabituation to S2 were obtained in both experiments. However, omission effects were not influenced by preexposure presentations of S1. Experiment 3, on the other hand, demonstrated that omission responding and dishabituation were attenuated by 20 preexposures of S1 when only 4 S1-S2 pairings were employed. In addition, Experiments 2 and 3 revealed that although expectation of S2 developed as a function of S1-S2 pairings, it too was reduced by preexposure to S1. Only Experiment 3 provided preexposure effects that are consistent with Wagner's (1981) theory. 相似文献
Although interest development is often conceptualized as a process that occurs within an individual, interest can be developed through various social mechanisms. Messages that suggest that one is or is not welcome within a context may serve to bolster or attenuate interest in those contexts. In a sample of first semester freshmen undergraduate science students, we tested whether or not talking with close others about one’s interests, and receiving social recognition during those conversations, was related to having a greater science career interest over time. Our findings suggest that the way in which students perceive others’ reactions to their scientific interests (social recognition) during these conversations may have the greatest impact on students that face greater external barriers to persisting. We found that positive social recognition appraisals that convey that a listener understands and encourages one’s interest in science predicted a greater science career interest over time for women, but not men. The impact of positive social recognition appraisals on interest in a science career was greatest among women with relatively low or average science identities, but not for women with a relatively high science identity. The implications for the development of students’ interest and for broadening participation in science are discussed.
Executive function is a broad construct that encompasses various processes involved in goal‐directed behaviour in non‐routine situations (Banich, 2009). The present study uses a sample of 560 5‐ to 16‐year‐old twin pairs (M = 11.14, SD = 2.53): 219 monozygotic twin pairs (114 female; 105 male) and 341 dizygotic twin pairs (136 female, 107 male; 98 opposite sex) to extend prior literature by providing information about the factor structure and the genetic and environmental architecture of the Behavior Rating Inventory of Executive Function (BRIEF; Gioia et al., 2000, Child Neuropsychol., 6, 235; Gioia et al., 2000, Behavior rating inventory of executive function, Lutz, FL: Psychological Assessment Resources), a multifaceted rating scale of everyday executive functions. Phenotypic results revealed a 9‐scale, 3‐factor model best represents the BRIEF structure within the current sample. Results of the genetically sensitive analyses indicated the presence of rater bias/contrast effects for the Initiate, Working Memory, and Task‐Monitor scales. Additive genetic and non‐shared environmental influences were present for the Initiate, Plan/Organize, Organization of Materials, Shift, and Monitor and Self‐Monitor scales. Influences on Emotional Control were solely environmental. Interestingly, the aetiological architecture observed was similar to that of performance‐based measures of executive function. This observed similarity provided additional evidence for the usefulness of the BRIEF as a measure of ‘everyday’ executive function. 相似文献
There are well documented links between close relationships and physical health, such that those who have supportive close relationships have lower rates of morbidity and mortality compared to those who do not. Inflammation is one mechanism that may help to explain this link. Chronically high levels of inflammation predict disease. Across the lifespan, people who have supportive close relationships have lower levels of systemic inflammation compared to people who have cold, unsupportive, conflict-ridden relationships. Not only are current relationships associated with inflammation, but past relationships are as well. In this article, we will first review the literature linking current close relationships across the lifespan to inflammation. We will then explore recent work showing troubled past relationships also have lasting consequence on people's inflammatory levels. Finally, we will explore developmental pathways that may explain these findings. 相似文献
