In the first few months of life, infants display spontaneous kicking which has been implicated as an important precursor to the development of later voluntary motor control. In the present study, the development of both intralimb and interlimb coordination in fullterm and low-risk preterm infants was examined by recording spontaneous kicking at 4 weekly intervals from 4 to 24 weeks of age. The relationship between the joint angles over this period was examined by measuring pairwise cross-correlation functions for the angular displacement curves of the hip, knee and ankle joints. In contrast to previous studies, intralimb coordination for both right and left legs was examined, and it was found that the legs produced different patterns of development. These patterns varied depending on which joint pair was investigated, and there was also evidence that leg asymmetries may be different for preterm and fullterm infants. This has possible implications for later hand and leg preferences. Interlimb coordination was also examined, and it appears that different patterns of development emerge for interlimb and intralimb coordination.PsycINFO classification: 2330; 2800  相似文献

Recent theories on the evolution of language (e.g. Corballis, 2009) emphazise the interest of early manifestations of manual laterality and manual specialization in human infants. In the present study, left- and right-hand movements towards a midline object were observed in 24 infants aged 4 months in a constrained condition, in which the hands were maintained closed, and in a free condition. A left-hand dominance for approach movements without contact with the object, and a right-hand dominance for reaching movements with object contact was observed in the free condition. In the constrained condition reaching movements of the right hand decreased dramatically. These results are interpreted as strong evidence of manual specialization in 4-month olds, with approach movements having a localization role and reaching movements announcing future right-hand dominance for prehension and object manipulation.  相似文献

Preterm infants avert their gaze more often and for longer periods in early social interactions compared to full term infants. In previous studies this finding is interpreted as being a function of the higher degree of parental stimulation that is often found in parents of preterm children. The current study explores an additional hypothesis. Since the development of general visual attention abilities is found to be less optimal in preterm children, it is possible that less optimal maturation of attention abilities partially explains the elevated gaze aversion in a social context. Therefore, the current study investigated the association between gaze aversion in a social context and the ability to disengage and shift visual attention in a non-social context in 20 preterm and 42 full term infants aged 4 and 6 months. Results confirm that preterm infants are slower to shift their attention in a non-social context and that they avert their gaze more often in a social context compared to full term children. Furthermore, more frequent gaze aversion during social interaction at 6 months was related to longer disengagement and the shifting of attention at 4 and 6 months, but only within the preterm group. The results suggest that attention maturation is less optimal in preterm children; this can be observed in a non-social as well as a social context. Less attention maturation in preterm children can negatively influence the amount of time they can stay actively involved in social interaction.  相似文献

Aim

To systematically review the efficacy of parenting interventions in improving the quality of the relationship between mothers and preterm infants.

Method

Randomized or quasi-randomized controlled trials (RCT) of parenting interventions for mothers of preterm infants where mother–infant relationship quality outcomes were reported. Databases searched: The Cochrane Library, PubMed, CINAHL, PsycINFO and Web of Science.

Results

Seventeen studies met the inclusion criteria, 14 with strong methodological quality. Eight parenting interventions were found to improve the quality of the mother–preterm infant relationship.

Conclusions

Heterogeneity of the interventions calls for an integrated new parenting program focusing on cue-based, responsive care from the mother to her preterm infant to improve the quality of the relationship for these mother–preterm infant dyads.  相似文献

Aim of the study was to evaluate the clinical characteristics and the treatment outcome of underweight patients with eating disorder (ED) not otherwise specified without amenorrhea (EDNOS-WA), compared with classical anorexia nervosa (AN) cases. Seventy-three consecutive female patients (57 AN, and 16 EDNOS-WA) were evaluated before and after a 20-week cognitive behaviour inpatient treatment (CBT-I). Assessment included anthropometry, the Eating Disorder Examination (EDE), the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory (STAI), and the Temperament and Character Inventory (TCI). At logistic regression analysis, amenorrhea was only predicted by baseline BMI and intense exercise, not by psychopathological variables. Response to CBT-I was good and similar between groups, without differences in the dropout rate or time-to-dropout. Our data lend support to the hypothesis that the criterion “amenorrhea” is of no clinical utility in the diagnosis and treatment of AN and could be removed in the forthcoming DSM-V proposal.  相似文献

The fear-avoidance (FA) model has gained widespread acceptance as a conceptual framework for investigating psychological factors such as FA beliefs and avoidance behavior, which contribute to chronic back pain and reduced functioning. Depressive symptoms are supposed to be related to FA beliefs and to foster avoidance behavior. This study aims to investigate the multivariate assumptions of the FA model with a focus on the role of depressive symptoms. A total of N = 360 patients with chronic nonspecific low back pain at admission of inpatient orthopedic rehabilitation participated in the survey. Measures included a numeric pain rating scale, Fear-Avoidance Beliefs Questionnaire, Pain Anxiety Symptoms Scale, Hannover Functional Ability Questionnaire and Patient Health Questionnaire. Using structural equation modeling (SEM), we construed a basic FA model and subsequently extended it by adding symptoms of depression as a covariate. The results of SEM indicated a good model fit for a basic FA model (χ²(263) = 431.069, p < .001, RMSEA = .042, CFI = .964, WRMR = .986). They confirmed the hypothesized relations and supported single mediations of the relationship between pain and functioning by FA beliefs and avoidance behavior. A second model including symptoms of depression as additional covariate (χ²(511) = 722.761, p < .001, RMSEA = .034, CFI = .956, WRMR = .949) showed a high impact of depressive symptoms on all FA model variables leading to a decrease of the FA mediations. The findings provide empirical support for the multivariate FA model and underline the importance of considering depressive symptoms in a multiple-target approach to understand the mechanisms of chronic pain.  相似文献

Using detailed clinical vignettes, the author argues that, despite the current idealization of the concept of forgiveness, the term has no place in psychoanalytic work, and there are some hazards to giving it one. Clinically, the concept of forgiveness is seductive, implying that there should be a common outcome to a variety of injuries, stemming from different situations and calling for different solutions. Every instance of what we call forgiveness can be seen to serve a different defensive function. While the conscious experience of what is called forgiveness is sometimes confused with the unconscious process of reparation, the two can only be described at different levels of psychic life. Despite the fact that in ‘the unconscious’ there is no such thing as forgiveness, the term has an adhesive quality in our thinking that also blunts the analyst'’s appreciation of the aggressive components in the work. In a final vignette, the author illustrates an analytic outcome that has the appearance of forgiveness, but is best understood as the complex result of the everyday work of analysis.  相似文献

I define humility as a virtue that includes both proper self‐assessment and a self‐lowering other‐centeredness. I then argue that humility, so understood, is a virtue in the context of sport, for several reasons. Humility is a component of sportspersonship, deters egoism in sport, fuels athletic aspiration and risk‐taking, fosters athletic forms of self‐knowledge, decreases the likelihood of an athlete seeking to strongly humiliate her opponents or be weakly humiliated by them, and can motivate an athlete to achieve greater levels of excellence in her sport. In the context of team sports, humility can contribute to an athlete being a better teammate, foster unity amidst diversity within a team, and contribute to the overall moral and athletic excellence of a team. I also argue that an individual who is truly the world's greatest athlete can know and communicate this truth, while remaining humble.  相似文献

The achievement of mastery in playing a composition by means of a musical instrument typically requires numerous repetitions and corrections according to the keys and notations of the music piece. Nevertheless, differences in the interpretation of the same music piece by highly skilled musicians seem to be recognizable. The present study investigated differences within and between skilled flute players in their finger and body movements playing the same piece several times on the same and on different days. Six semiprofessional and four professional musicians played an excerpt of Mozart’s Flute Concerto No. 2 several times on three different days. Finger and body movements were recorded by 3D motion capture and analyzed by linear and nonlinear classification approaches. The findings showed that the discrete and continuous movement timing data correctly identified individuals up to 100% by means of their finger movements and up to 94% by means of their body movements. These robust examples of identifying individual movement patterns contradict the prevailing models of small, economic finger movements that are favored in the didactic literature for woodwind players and question traditional recommendations for teaching the learning of motor skills.  相似文献

The present paper selectively reviews the literature which compares full-term and preterm infants' communication with their mothers in the first year of life. The review is focused not only on what differences are found between full-term and preterm infants, but also why such differences exist. Particular emphasis is placed on the importance of interpreting the findings in the light of the developmental phase of the infants, the heterogeneity of the preterm population and the situation in which communication is studied. Most studies were not designed to consider these issues in any detail. Differences with respect to these factors can be found between studies, however, which may have contributed to the often contradictory findings. Consequently, comparisons between these studies provide clues about the effects of these factors on communicative development. The ultimate goal of this review is to point to important directions for future research on early communication in preterm infants.  相似文献

Do Ss compare multidigit numbers digit by digit (symbolic model) or do they compute the whole magnitude of the numbers before comparing them (holistic model)? In 4 experiments of timed 2-digit number comparisons with a fixed standard, the findings of Hinrichs, Yurko, and Hu (1981) were extended with French Ss. Reaction times (RTs) decreased with target-standard distance, with discontinuities at the boundaries of the standard's decade appearing only with standards 55 and 66 but not with 65. The data are compatible with the holistic model. A symbolic interference model that posits the simultaneous comparison of decades and units can also account for the results. To separate the 2 models, the decades and units digits of target numbers were presented asynchronously in Experiment 4. Contrary to the prediction of the interference model, presenting the units before the decades did not change the influence of units on RTs. Pros and cons of the holistic model are discussed.  相似文献

Sehnsucht, the longing or yearning for ideal yet seemingly unreachable states of life, is a salient topic in German culture and has proven useful for understanding self-regulation across adulthood in a German sample (e.g., Scheibe, Freund, & Baltes, 2007). The current study tested whether findings for German samples could be generalized to the more individualistic and agentic U.S. American culture. Four samples of U.S. American and German participants (total N = 1,276) age 18 to 81 years reported and rated their 2 most important life longings and completed measures of subjective well-being and health. Measurement equivalence was established at the level of factor loadings for central life longing characteristics. German and U.S. American participants did not differ in self-reported ease of identifying personal life longings or their intensity. In comparison to Germans, however, U.S. Americans associated life longings less with utopian, unattainable states and reported less salience of the concept in everyday life. Associations with measures of adaptation suggest that life longings can be both functional and dysfunctional for development in both cultures.  相似文献

The delay discounting paradigm was used to examine its utility in understanding motivational factors among socially anxious individuals. Participants (n=88) who reported high and low levels of social anxiety were randomly assigned to either a social threat or non-threat condition and their subsequent rates of discounting were examined. A significant difference in rates of discounting was found between the high and low social anxiety groups within the non-threat condition, with high social anxiety participants showing increased discounting. This study suggests that a modified version of the delay discounting paradigm may be useful in understanding motivational factors in social anxiety.  相似文献

Eight-year-old British children were found to be less accurate at rejecting pseudohomophones than ordinary nonwords in a lexical decision task, but 8-year-old New Zealand children did not show this effect. A subsequent homophone decision task showed that this difference was not due to the New Zealand children being unable to distinguish pseudohomophones from other nonwords. The New Zealand children, however, were less accurate than the British children in pronouncing the pseudohomophones they had identified. It was argued that the British children tended to sound out the items before making a choice in the lexical decision task, which gave salience to phonological rather than visual information, resulting in increased errors to the pseudohomophones. It was concluded that where the British children showed this dependency on use of phonological information it was a product of the teaching approach they had experienced.  相似文献
