In the debate concerning the effects of day care on infant development, insufficient attention has been paid to the potential relationship between pre‐existing emotional differences among mothers and the type of care they choose for their infants. To shed light on this issue, this study examines the attachment representations of mothers who choose day‐care centres as opposed to mothers who choose to remain at home with their infants. Participants were 76 primiparous mothers. Mothers' attachment classifications were assessed by the Adult Attachment Interview [AAI; Main M, Kaplan N, Cassidy J. 1985. Security in infancy, childhood, and adulthood: a move to the level of representation. In Growing Points of Attachment Theory and Research. Monograph of the Society for Research in Child Development, 50, (1–2, serial no. 209), Bretherton I, Waters E (eds); 66–104]. Results indicate that more Day‐care than Home‐Care mothers are classified as insecurely attached. These results highlight the contribution of maternal emotional characteristics to the effects of diverse child care arrangements on infant development.

Associations between parental play styles and sibling interaction were investigated in 30 same‐sex preschool‐ and school‐aged sibling dyads (first‐borns were 4–9 years, M=6.6 years; second‐borns were 2–7 years, M=4.2 years), divided into older and younger sibling groups. Participants completed puzzles under three conditions: (a) siblings alone, (b) together with mother, and (c) together with father. Prosocial and agonistic sibling‐directed behaviors and positive and negative parent–child behaviors were coded. Siblings engaged in both more prosocial and agonistic interactions when alone than with either parent; there were no differences in sibling interactions in the mother versus father episodes. Paternal negative behavior was associated with sibling agonistic behavior when the children were alone, indicating second‐order effects, however, mother–child and sibling interactions were not significantly associated. Nevertheless, reciprocity in positive and negative behaviors directed by children to parents and vice versa was evident, demonstrating synchrony in patterns of exchanges. The findings underscore the necessity of studying both parents in order to understand more fully the dynamics involved in family relationships.

A task that requires subjects to determine whether two forms of the same shape, but in different orientations, are mirror images or identical except for orientation is called a handedness recognition task. Subjects' reaction times (RT) on this task are consistently related to the angular disparity (termed alpha) between the two presented forms. This pattern of data has been interpreted to indicate that subjects solve the task by imagining that one of the forms rotates into the orientation of the other (termed mental rotation). The speed with which one imagines one of the forms rotating has been widely considered a fixed capability of the individual, and thus immune to the effect of contingencies. We present an experiment that assesses the effects of temporal contingencies in a handedness recognition task on the slope of the function RT = f(alpha). The data indicate that the slope of this function can come under the control of temporal contingencies.  相似文献

A substantial amount of data has accumulated demonstrating that emotionally disordered subjects are prone to bias their attention toward threatening, emotionally relevant stimuli. Little attention has been reserved for the study of cognitive processes involved in anger arousal. In the present study, we investigated whether mood-congruent attentional biases could be demonstrated in subjects of varying levels of trait anger using a visual search task. This task also assessed whether mood-congruent biases diminished with repeated exposure to specific emotion stimuli. To investigate state-trait interaction effects, a naturalistic, anger-inducing insult was administered to half the subjects. There was a positive relation between participants' level of trait anger and their degree of mood-congruent attentional bias toward anger-related cues only after an insult. As predicted, this effect diminished across blocks of trials. Aggr. Behav. 24:399–409, 1998. © 1998 Wiley-Liss, Inc.  相似文献

I contrast two solutions to the lottery paradox concerning knowledge: contextualism and subject-sensitive invariantism. I defend contextualism against an objection that it cannot explain how 'knows' and its cognates function inside propositional attitude reports. I then argue that subject-sensitive invariantism fails to provide a satisfactory resolution of the paradox.  相似文献

Taking a cue from recent discoveries of directional bias in microsaccades during visual fixation, we investigated directional bias in tremor during manual pointing. Subjects memorized and then performed patterns of alternating postures and voluntary movements. The directions of the tiny movements occurring during periods of intended stillness were predictive of subsequent target-directed movements such that in the horizontal axis, relative to baseline, the frequency of tremor decreased and the amplitude of tremor increased before horizontal movements, but not before vertical movements. This effect was less pronounced in the finger than in the arm, forearm, and hand. Possible explanations of the effect are based on eye-limb coupling, decreasing stiffness in the axis of forthcoming movement, and release of inhibition. The discovery of directionally specific preparatory activity suggests that the simple task of holding still before moving may provide a new window into the processes that allow for the translation of intentions into actions.  相似文献

Evaluating a youth program whose goals are to provide instruction in Cambodian dance, increase awareness and pride in Cambodian culture, promote healthy behaviors, and create linkages within the community has been a challenge. A primary source of conflict was incorporating evaluation methods that were required of all funded programs with our own specifically tailored measures. One of our concerns was that the required tools were not culturally appropriate for our participants. Our experiences reinforce the importance of forming partnerships that embrace principles of respect, equity, and empowerment among all involved before establishing a research agenda. The choices we made and did not make contributed to our struggles and frustration and also to the insight that was gained. Our analysis examines the importance of clear communication, cultural awareness, tailoring evaluation, and meaningful participation. We believe that the lessons we learned will help facilitate the conduct of culturally sensitive community-based research.  相似文献

Brain imaging studies reliably localize a region of visual cortex that is especially responsive to visual words. This brain specialization is essential to rapid reading ability because it enhances perception of words by becoming specifically tuned to recurring properties of a writing system. The origin of this specialization poses a challenge for evolutionary accounts involving innate mechanisms for functional brain organization. We propose an alternative account, based on studies of other forms of visual expertise (i.e. bird and car experts) that lead to functional reorganization. We argue that the interplay between the unique demands of word reading and the structural constraints of the visual system lead to the emergence of the Visual Word Form Area.  相似文献
