This study tested the effects of optimized neonatal mother–infant transactions on joint attention performance at 12 months. Surviving infants <2000 g from a geographically defined area were randomly assigned to a preterm intervention (n = 71) or preterm control group (n = 69). Comparisons were made between preterm groups, secondary with a term group (n = 75). Joint attention was measured using the Early Social Communication Scales. Preterm intervention infants scored significantly higher than preterm control infants on elements Initiating Joint Attention (p < 0.05), Initiating Object Requests (p < 0.05), and Responding to Social Interaction (p < 0.0005). Intervention was not associated with performance on elements Responding to Joint Attention, or on Responding to Requests. ELBW infants scored significantly lower than VLBW and LBW infants on imperative functions. Girls outperformed boys on all communication elements. An intervention implemented during the neonatal period can be of advantage for certain aspects of joint attention performance in preterm infants. 相似文献

Several studies have indicated a clear correspondence in the durations of active versus mentally simulated actions. The present study examined whether this would also be found when a new and unfamiliar task (the pedalo) was given to 15 sports students aged 21 to 27 years, and the range of mental simulation was extended to cover two different modalities. Despite several modifications of experimental procedure, results always showed high correlations between actual and mental durations similar to those reported for walking by Decety, Jeannerod, and Prablanc in 1989. There were also higher scores on absolute error. However, there were no significant differences between mental simulations with open versus closed eyes. It is concluded that the timing of the execution and mental simulation of closed and cyclical movements is interrelated and based on common mechanisms. 相似文献

The relationship between defensive strategies as measured by the Meta-Contrast Technique (MCT) and self-reported trait anxiety, trait aggression and defensiveness, as measured by the Karolinska Scales of Personality (KSP), was investigated in 83 healthy men. Further aims of the study were to describe and document how a healthy and demographically well defined group of subjects responded to the MCT, and to investigate whether age, personality traits and cognitive abilities influenced the reports of picture recognition thresholds in the MCT. The results indicated no agreement between the conceptualization of anxiety as measured by the MCT and anxiety as measured by the KSP inventory. Nor was there any agreement between defensive strategies in the MCT and trait defensiveness as defined with the KSP. However, age, personality traits, and cognitive abilities all contributed to explain the variations in the threshold values of recognition of stimuli pictures, all of which are of central importance in the scoring of MCT protocols. 相似文献

Twelve sleep-deprived and 13 non-deprived Navy cadets were tested with the dichotic listening procedure for effects of sleep deprivation on hemispheric asymmetry and sustained attention. Consonant-vowel syllables were presented to the subjects in three different conditions, a divided (non-forced) attention condition, a forced right ear and a forced left ear attention condition. In the two forced attention conditions the subjects were instructed to focus attention only on the right or left ear stimulus. The results showed an expected right ear advantage for both groups during the non-forced and forced right attention conditions, indicating superior left hemisphere processing. During the forced left attention condition, the sleep-deprived subjects showed no ear advantage at all, while the non-deprived subjects showed an expected left ear advantage. The results are discussed within a theoretical framework of a dual process model, where sleep deprivation disrupts the ability to sustain attention, caused by a temporary failure of the right hemisphere's top-down (instruction-driven) processing to override the left hemisphere's bottom-up (stimulus-driven) processing. 相似文献

Four experiments investigated the memory distortions for the location of a dot in relation to two horizontally aligned landmarks. In Experiment 1, participants reproduced from memory a dot location with respect to the two landmarks. Their performance showed a systematic pattern of distortion that was consistent across individual participants. The three subsequent experiments investigated the time course of spatial memory distortions. Using a visual discrimination task, we were able to map the emergence of spatial distortions within the first 800 msec of the retention interval. After retention intervals as brief as 50 msec, a distortion was already present. In all but one experiment, the distortion increased with longer retention intervals. This early onset of spatial memory distortions might reflect the almost immediate decay of detailed spatial information and the early influence of an enduring spatial memory representation, which encodes spatial information in terms of the perceived structure of space. 相似文献

The objective of this article is to investigate ethical aspects of technology through the moral term “paternalism”. The field
of investigation is medicine. The reason for this is twofold. Firstly, “paternalism” has gained moral relevance through modern
medicine, where physicians have been accused of behaving paternalistic and threatening patients’ autonomy. Secondly, medicine
is a brilliant area to scrutinise the evaluative aspects of technology. It is argued that paternalism is a morally relevant
term for the ethics of technology, but that its traditional conception is not adequate to address the challenges of modern
technology. A modification towards a “technological paternalism” is necessary. That is, “technological paternalism” is a fruitful
term in the ethics of technology. Moreover, it is suited to point out the deficiencies of the traditional concept of paternalism
and to reform and vitalise the conception of paternalism in ethics in order to handle the challenges of technology. 相似文献

A partially-controlled intervention study was performed. Female patients with rheumatoid arthritis (RA) were allocated to three groups: the network intervention group (n = 104), the attention control group (n = 85), and the no-treatment control group (n = 75). The network intervention consisted of an assessment session and a network meeting. Patients were assessed at baseline and approximately 10 and 18 months after the intervention. The network intervention group reported an increase in network size. Daily emotional support increased for the intervention patients compared with patients in the attention control group. The degree of social dysfunction was reduced for patients in the intervention group compared to patients in the no-treatment control group. Furthermore, for single patients, the intervention significantly increased the social network size and improved both social functioning, and perceived overall health, compared to both control groups. The results suggest that the social needs of single patients should be given special attention in clinical settings. 相似文献

Housing design and people with severe mental illness: An observational approach to the investigation of supported housing facilities 下载免费PDF全文
Elizabeth Marcheschi Maria Johansson Thorbjörn Laike David Brunt 《Scandinavian journal of psychology》2016,57(1):12-21
An observational approach was employed to investigate the role played by architectural characteristics of supported housing facilities (SHF) in sustaining interactional behavior among people with severe mental illness (SMI) (N = 29) and staff (N = 27). The observations were carried out in dining areas, corridors and outdoor environments of SHF (N = 4). In order to test differences in the observed behaviors two SHFs with high physical‐environment quality (HQ) and two with low physical‐environment quality (LQ) according to the perception of people with SMI were chosen. Results showed that the dining areas of HQ better support social interactions between SHF users. No differences between the housing facilities were found concerning corridors areas, while housing facilities that provided proximity and accessibility to outdoor environments, such as those with HQ, were significantly more supportive for social interactional behavior than LQ housing. These results corroborate previous findings from this project and suggest that the characteristics of the housing design have a significant impact on the use of the environment and on the behavior patterns in the setting. 相似文献
