Ample research has demonstrated the benefits of basic autonomy supportive practices (e.g., perspective-taking, choice, minimizing-control) for adolescents’ psychosocial functioning. Herein, we posit that there is one additional autonomy supportive practice with specific importance for adolescents’ development: Reflective Authentic Inner Compass facilitation. This practice is posited to contribute to the formation of an Authentic Inner-Compass: An action-guiding schema, informing youth on what they truly value, need, and want, and consisting of two parts: (1) A foundation including authentic values, interests, and life-aspirations, and (2) Autonomous commitment to future-oriented goals and decisions, based on the foundation. A longitudinal study of 18–19 year-old Israeli adolescents showed that perceived Reflective Authentic Inner Compass Facilitation by instructors uniquely predicted (beyond Basic Autonomy Support) adolescents’ experience of having an authentic inner-compass in the military domain, which then predicted autonomous engagement in plan-promoting activities. A cross-sectional study with 16?18 year-old Belgian adolescents showed that perceived Reflective Authentic Inner Compass Facilitation by parents uniquely predicted (beyond Basic Autonomy Support) the experience of having an authentic inner-compass, which then related positively to well-being. Implications of the notion of the authentic inner compass for the conceptualization of autonomy support and the experience of autonomy are discussed.
Accumulated evidence from electrophysiology and neuroimaging suggests that face perception involves extrastriate visual mechanisms specialized in processing physiognomic features and building a perceptual representation that is categorically distinct and can be identified by face-recognition units. In the present experiment, we recorded event-related brain potentials in order to explore possible contextual influences on the activity of this perceptual mechanism. Subjects were first exposed to pairs of small shapes, which did not elicit any face-specific brain activity. The same stimuli, however, elicited face-specific brain activity after subjects saw them embedded in schematic faces, which probably primed the subjects to interpret the shapes as schematic eyes. No face-specific activity was observed when objects rather than faces were used to form the context. We conclude that the activity of face-specific extrastriate perceptual mechanisms can be modulated by contextual constraints that determine the significance of the visual input. 相似文献
The authors sought to gain further knowledge about activation of target muscles during imagery engagement in a motor task. Six hemiparetic patients and 9 healthy participants performed 3 real rises on tiptoes and then, after pausing, 3 imagery rises on tiptoes. Metronome beats guided the rate of rises and descents. Electromyographic (EMG) activity from the medial gastrocnemius and the rectus femoris muscles were monitored bilaterally throughout the performance of both tasks. In 3 healthy participants and 3 individuals with hemiparesis, EMG activity was related to the imagery task in at least 1 of the target muscles. Conversely, in the other participants, motor imagery practice was not accompanied by task-related EMG activity in the monitored muscles. In all cases, the increment in activation level during motor imagery practice was very low in comparison with that of real performance. The findings were not unequivocal; therefore, EMG activity may sometimes, but not always, be recorded during motor imagery practice both in healthy individuals and in poststroke hemiparetic participants. Further research is needed to align motor imagery practice with the objectives of motor rehabilitation. 相似文献
The present study examined the role of alerting in modulating attentional bias to salient events. In a global/local processing task, participants were presented with a large arrow (global level) comprised of smaller arrows (local level) pointing in the same or opposite directions and had to indicate the direction of the large or small arrows in different blocks. Saliency of the global and local levels was manipulated, creating global-salient and local-salient conditions. Alerting signals were presented in half of the trials prior to the target. Results revealed a double dissociation in the effects of alerting on global/local interference effects. In a global salient condition, alerting increased global interference and decreased local interference. In a local salient condition, alerting reduced global interference and increased local interference. We demonstrate that within a single task, alerting can increase and reduce conflict based on perceptual saliency. These findings help to better understand disorders like hemispatial neglect in which both arousal and attention to salient events are impaired. These results also challenge previous theories suggesting that alerting acts to increase conflict interference. We argue that alerting is an adaptive mechanism that diverts attention to salient events, but comes at a cost when selective attention to less salient details is required. 相似文献
