A normative perspective on motivation 总被引:6,自引:0,他引:6
Understanding the effects of motivation on instrumental action selection, and specifically on its two main forms, goal-directed and habitual control, is fundamental to the study of decision making. Motivational states have been shown to 'direct' goal-directed behavior rather straightforwardly towards more valuable outcomes. However, how motivational states can influence outcome-insensitive habitual behavior is more mysterious. We adopt a normative perspective, assuming that animals seek to maximize the utilities they achieve, and viewing motivation as a mapping from outcomes to utilities. We suggest that habitual action selection can direct responding properly only in motivational states which pertained during behavioral training. However, in novel states, we propose that outcome-independent, global effects of the utilities can 'energize' habitual actions. 相似文献

C. R. Gallistel and J. Gibbon (2000) presented quantitative data on the speed with which animals acquire behavioral responses during autoshaping, together with a statistical model of learning intended to account for them. Although this model captures the form of the dependencies among critical variables, its detailed predictions are substantially at variance with the data. In the present article, further key data on the speed of acquisition are used to motivate an alternative model of learning, in which animals can be interpreted as paying different amounts of attention to stimuli according to estimates of their differential reliabilities as predictors. 相似文献

In an era of global threats, understanding the implications of disasters on young people's life course is of central importance. A particular emphasis should be placed on non-Western economically developing societies that are considered as vulnerable and are less studied, and on social groups within these societies that are underrepresented. The present study focuses on young Sri Lankan women who experienced the 2004 Indian Ocean tsunami as children. Thirteen young women generated their life stories in semi-structured interviews, 12 years after the disaster had elapsed. Holistic narrative analysis revealed new variations and in-depth meanings in disaster response trajectories and presented the intertwining courses of the responses to the Potentially Traumatic Event (PTE) with ecological aspects throughout development, as in Trajectories intertwining with Life (TiL). This study provides empirical, methodological, conceptual and practical innovations to the study of human development throughout the life course, within the interdisciplinary fields of trauma and disasters.
Highlights
- This research is interested in how childhood disaster response trajectories among an understudied population are understood through an ecological-developmental perspective.
- Life stories uncover Trajectories intertwining with Life (TiL) among Sri Lankan women who were children during the Indian Ocean tsunami.
- The TiL unique outcomes, integrating trauma responses as inseparable from ecological and developmental aspects, offer various theoretical and applied implications.
