This study, conducted on a sample of 403 adult subjects, set out to explore the relationships between measures of digit span (forward and reversed), motor and spatial span, and their dependence on a broad range of measures of cognitive function. The results revealed that measures of digit span are closely related, as are measures of motor and spatial span, but these pairs of memory span measures are relatively independent of each other. Furthermore, reverse digit span, motor span, and spatial span appear to rely on what might be regarded as intellectual or executive cognitive functions. As such, the results provide little support for accounts of serial recall, which suggest that order and/or item information are more adequately modelled in a modality-independent form. 相似文献

A lack of consensus persists as to whom exactly the dialogues of Wittgenstein's Philosophical Investigations are between: Wittgenstein and an interlocutor? Or perhaps a variety of interlocutors, none of whom can be identified with Wittgenstein himself? I argue here that this lack of consensus is possibly due to an ambiguity in the ordinary concept of “talking to oneself,” and that a new concept of “talking to oneself” appropriate to Wittgenstein's dialogues is needed to properly understand them. Wittgenstein is talking to himself—but he is doing so in the way we talk to other people. 相似文献

Neonates were assessed at delivery and again at 1 month by examiners and by their depressed or nondepressed mothers. Examiner assessments were conducted using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Maternal assessments were conducted by mothers using a simplified version of the NBAS, the Mother's Assessment of the Behavior of her Infant (MABI). Examiners rated neonates of depressed mothers lower than infants of nondepressed mothers on state organization. At delivery, newborn infants of depressed mothers were given lower state regulation scores by their mothers than by the examiners and, 1 month later, examiners’ state regulation ratings were as negative as those of the depressed mothers. Conversely, infants of nondepressed mothers were given higher social interaction scores by their mothers than by the examiners, and 1 month later, examiner ratings of social interaction were as positive as those of the nondepressed mothers. These findings suggest that infants of depressed mothers may be placed at risk by prenatal influences and by risks associated with maternal perceptions. Perceptions of infants appear to be colored by maternal depression status as early as the immediate postpartum period and, though “subjective,” these perceptions are predictive of infant outcomes. 相似文献

To determine whether mildly and moderately dysphoric adolescent mothers display infantized facial and vocal behaviors, 21 nondysphoric mothers and 32 dysphoric (16 mildly and 16 moderately/severely dysphoric) mothers were videotaped during face-to-face interactions with their 4-month-old infants. Mildly dysphoric mothers showed less positive facial expressions and less animated/exaggerated vocal expressions. The moderately/severely dysphoric mothers, however, did not differ from nondysphoric mothers in their display of facial and vocal behaviors. These mothers with higher Beck Depression Inventory (BDI) scores may have become concerned about their many symptoms affecting their interactions and tried to compensate for this during their interactions. A second study was conducted to determine whether completing the BDI before interactions positively affected the moderately/severely dysphoric mothers' behavior. Moderately/severely dysphoric mothers (N=24) and mildly dysphoric mothers (N=24) were given the Beck Depression Inventory either before or after their face-to-face interactions with their 4-month-old infants. Moderately/severely dysphoric mothers who were given the BDI before their interactions showed more positive behavior than mothers given the BDI after their interactions. © 1997 Michigan Association for Infant Mental Health 相似文献

The present study assessed fathers' and mothers' relative involvement in infant caregiving tasks in 34 low-income African–American and Hispanic–American families. Analysis showed that involvement in childcare differed as a function of the gender of the parent. Fathers spent one half the time mothers did in caregiving. However, fathers' and mothers' participation in caregiving did not vary as a function of ethnic group. African–American parents reported to have received more family support than Hispanic–American parents. Although relationships were noted between age, income, education, length of marriage, social support, and involvement in infant caregiving, these sociodemographic variables did not predict parents' participation in childcare. The results are discussed in relation to the preconceived notion that low-income, minority fathers are ‘uninvolved’. ©1997 John Wiley & Sons, Ltd. 相似文献

Interaction behaviours of 88 adolescent mothers with depressive symptoms and their 3-month-old infants were videotaped and coded for different types of touch. The ‘depressed’ mothers were classified as intrusive, withdrawm or good by one observer and another observer coded rough tickling, poking, tugging and pulling as negative touch behaviours and gentle stroking and rubbing as positive touch behaviours. The mothers with depressive symptoms were more likely to touch their infants in a negative way and more likely to be classified as intrusive. 相似文献

Twenty‐four newborns (M age = 12 days) of depressed and nondepressed mothers were assessed for oral perception of a nubby and smooth texture. Both groups of newborns discriminated between these textures and showed a sucking preference for the smooth texture. However, the newborns of depressed mothers spent 50% less time orally exploring the stimuli, one‐third less time exploring the more novel nubby texture, and 59% less time mouthing the smooth texture. Newborns of depressed mothers may have biological differences that affect their emotional arousal and emotional regulation (e.g., capacity for self‐soothing). © 2000 Michigan Association for Infant Mental Health. 相似文献

Three pigeons chose between random-interval (RI) and tandem, continuous-reinforcement, fixed-interval (crf-FI) reinforcement schedules by pecking either of two keys. As long as a pigeon pecked on the RI key, both keys remained available. If a pigeon pecked on the crf-FI key, then the RI key became unavailable and the crf-FI timer began to time out. With this procedure, once the RI key was initially pecked, the prospective value of both alternatives remained constant regardless of time spent pecking on the RI key without reinforcement (RI waiting time). Despite this constancy, the rate at which pigeons switched from the RI to the crf-FI decreased sharply as RI waiting time increased. That is, prior choices influenced current choice-an exercise effect. It is argued that such influence (independent of reinforcement contingencies) may serve as a sunk-cost commitment device in self-control situations. In a second experiment, extinction was programmed if RI waiting time exceeded a certain value. Rate of switching to the crf-FI first decreased and then increased as the extinction point approached, showing sensitivity to both prior choices and reinforcement contingencies. In a third experiment, crf-FI availability was limited to a brief window during the RI waiting time. When constrained in this way, switching occurred at a high rate regardless of when, during the RI waiting time, the crf-FI became available. 相似文献
