Human newborns can propel themselves to their mother's breast when positioned skin to skin on her abdomen just after birth. For decades, researchers have considered this primitive crawling behavior a spinal reflex, immune to supra spinal control. However, recent research suggests that neonatal crawling is already responsive to visual and olfactory stimuli processed at a supra spinal level. Here we report that a few hours post birth, French newborns can also modulate their crawling in response to their native language – a source of information that is processed supra-spinally. The crawling patterns of 23 French-born newborns were recorded on video and via an infrared motion capture system during two randomly ordered 2-min trials. The newborns were secured on a mini skateboard to facilitate arm and leg movements during their crawling propulsion. They heard a repetitive sequence of the same sentences either in French, their native language, or in English, a rhythmically different and hence discriminable unfamiliar language, on each trial. In French, compared to English, crawling was enhanced, with significantly more arm and leg steps and significantly more and larger trunk rotations in the cephalo-caudal axis. Moreover, newborns rotated their heads and trunk toward the appropriate loud speaker when hearing French but not English. These preliminary findings suggest that newborn crawling is not a simple stereotyped reflex under spinal control, but a complex pattern that can be modulated in response to higher-order, supra-spinally processed stimuli. The findings open fascinating questions about the range of stimuli to which newborn crawling is responsive. 相似文献

The present article reviews recent work with the Sentence Completion Method (SCM) and examines the method's effectiveness as an assessment instrument. Studies in which the SCM was employed in testing hypotheses concerning personality and its development, as well as reports that deal with maladaptive functioning and psychopathology are covered. Also reviewed is some work that investigates the nature of the method itself. The overall conclusion is that the SCM is flexible, readily adaptable in various research and clinical settings, and to be recommended for continuing use and application. 相似文献

Social network as a moderator between trauma exposure and post-trauma symptomatology was studied. Two samples--relief workers and UN soldiers--were assessed on trauma exposure, social network and three dependent measures related to post-trauma reactions. Regression analysis and interaction plots were used to determine the presence of interaction effects between trauma exposure and social network. All four network variables moderated the relationship between trauma exposure and post-trauma reactions among relief workers, while among UN soldiers only two such buffer effects were found. Furthermore, among UN soldiers one of these interaction effects was reversed, indicating social support to be important for those low on trauma exposure, while among relief workers support was important in the high-exposure condition. The results indicate a difference with respect to the importance of social network as a moderator between groups exposed to different kinds of war trauma. Differences in motivational systems may also exist. However, further research will have to establish this. 相似文献
