This study examined the role of the level and variability of happiness, anger, anxiety, and sadness in the development of
adolescent-reported anxiety disorder symptoms, depressive symptoms, and aggressive behavior in 452 adolescents (250 male)
followed from age 13 to 14. Level and between-day variability of emotions were assessed through adolescent report at 3-month
intervals across a 1 year period. Level and variability of the four emotions contributed to changes in anxiety disorder and
depressive symptoms more consistently than to changes in aggressive behavior. All four emotions were predictive of changes
in internalizing problems, while anger played the most prominent role in the development of aggressive behavior. Variability
of emotions contributed to changes in anxiety disorder symptoms, while heightened levels of negative emotions and diminished
happiness contributed to changes in depression. Results suggested somewhat stronger effects of negative affect on aggressive
behavior for females than for males. Results underscore the role of emotion dysregulation in the development of psychopathology. 相似文献
Decay theory posits that memory traces gradually fade away over the passage of time unless they are actively rehearsed. Much recent work exploring verbal short-term memory has challenged this theory, but there does appear to be evidence for trace decay in nonverbal auditory short-term memory. Numerous discrimination studies have reported a performance decline as the interval separating two tones is increased, consistent with a decay process. However, most of this tone comparison research can be explained in other ways, without reference to decay, and these alternative accounts were tested in the present study. In Experiment 1, signals were employed toward the end of extended retention intervals to ensure that listeners were alert to the presence and frequency content of the memoranda. In Experiment 2, a mask stimulus was employed in an attempt to distinguish between a highly detailed sensory trace and a longer-lasting short-term memory, and the distinctiveness of the stimuli was varied. Despite these precautions, slow-acting trace decay was observed. It therefore appears that the mere passage of time can lead to forgetting in some forms of short-term memory. 相似文献
It has become increasingly common for young children to be taken care of by multiple caregivers in China after the socio-economic reforms. Complex migration patterns and high female labour force participation have led to children receiving care from various individuals in different contexts. However, little is known about how childcare arrangements are associated with child health well-being. This study examines various early childhood caregivers and their influences on children’s physical health in China. Using data from the China Health and Nutrition Survey (CHNS 1991–2011) with 3,470 children aged 2 to 6, we first identified different types of childcare arrangements in and outside of the household based on who provides the care, where they provide the care, and the intensity of the care. Then we examined the relationship between various childcare arrangements and health outcomes for children. Overall, household members undertook early childhood care tasks in China, with an increase in grandparents as primary caregivers between 1991 and 2011. The proportion of children receiving formal childcare fluctuated around 20% during this period. The findings suggest that: 1) primary caregiver in the household other than parents is not associated with undesirable physical health outcomes; 2) formal childcare outside the household is associated with higher height and lower BMI scores; 3) primary caregivers in the household, particular grandparents, moderate the association between childcare arrangements outside the household and children’s health outcomes. It yields an implication that early childhood care policies incorporating multiple caregivers would benefit children’s well-being in China.
This article examines the multiple relations between the rationalist tradition of French philosophy of science exemplified by the work of Gaston Bachelard, and the rethinking of the relation between science and ideology undertaken by Louis Althusser and a young Alain Badiou in the 1960s. Both Bachelard and Althusser are interrogated for the philosophy of language that underpins their respective visions of scientificity; in turn, the problem of the subject is posed, in part through an investigation of Althusser's inheritance and transformation of Lacanian psychoanalysis. 相似文献
Researchers have investigated visual search behavior for almost a century. During that time, few studies have examined the cognitive processes involved in hiding items rather than finding them. To investigate this, we developed a paradigm that allowed participants to indicate where they would hide (or find) an item that was to be found (or hidden) by a friend or a foe. We found that (i) for friends more than foes, participants selected the pop-out item in the display, and (ii) when the display was homogeneous, they selected nearby and corner items. These behaviors held for both hiding and finding, although hide and find behaviors were not identical. For pop-out displays, decision times were unusually long when hiding an item from a foe. These data converge on the conclusion that the principles of search and concealment are similar, but not the same. They also suggest that this paradigm will provide researchers a powerful method for investigating theory of mind in adults. 相似文献
Increasing numbers of counsellors practise using social constructionist (e.g. narrative, collaborative language systems and solution-focused) approaches. Social constructionist theory holds that matters such as 'understanding' are constructed and upheld in human interaction though counselling approaches derived from this theory offer little insight on how this might occur. The present study adopts a theoretically compatible research approach (ethnomethodology and conversation analysis) to empirically examine how understandings were purportedly constructed in counselling interviews. Understanding is depicted in conversational interaction terms, in how speakers make evident to each other that their shared talk is adequate for 'moving forward'. Counsellor and client perceptions of their participation in researcher-selected passages of 'understanding' supplement the analyses. This preliminary study sheds light on some pragmatic considerations useful in practising constructionist forms of counselling. 相似文献
