Goal-directed behavior is a fundamental means by which animals can flexibly solve the challenges posed by variable external and internal conditions. Recently, the processes and brain mechanisms underlying such behavior have been extensively studied from behavioral, neuroscientific and computational perspectives. This research has highlighted the processes underlying goal-directed behavior and a...

Michaela Riediger Research Scientist Center for Lifespan Psychology Max Planck Institute for Human Development Berlin, Germany Every once in a while, we all encounter situations in which we think about what we want to attain, maintain, or avoid in the future. No matter which goals we set ourselves in such situations—to spend more time with friends, learn Spanish, find a better-paid job, lose we...

Abstract Past research has continuously shown that motivation in school declines across adolescence. To counteract potential educational practice, the present study examines motivational development of early and middle adolescent students within one year two distinctive learning environments: a conventional teacher-directed environment an individualized student-directed based on competency matr...

In order to behave adaptively, attention can be directed in space either voluntarily (i.e., endogenously) according to strategic goals, or involuntarily (i.e., exogenously) through reflexive capture by salient or novel events. The emotional or motivational value of stimuli can also strongly influence attentional orienting. However, little is known about how reward-related effects compete or int...

background and purpose: despite the high prevalence of chronic obstructive pulmonary disease, there haven,t been definite curative treatment for the disease and focus of treatment has directed towards pulmonary rehabilitation as an effective non-drug treatments. this study were performed to determine the effect of motivational abdominal breathing device on breathing pattern and dyspnea of chron...

We examined the effect of antisera directed at specific G-protein subtype(s) on dynorphin A (Dyn A)-mediated reduction of calcium currents in rat dorsal root ganglia (DRG) neurons. Whole cell patch-clamp recordings were performed on acutely dissociated neurons. Dyn A (1 microM)-mediated decrease in calcium currents was inhibited > 90% by the preferential kappa-receptor antagonist norbinaltorphi...

Low-order quantum resonances manifested by directed currents have been realized with cold atoms. Here we show that by increasing the strength of an experimentally achievable delta-kicking ratchet potential, quantum resonances of a very high order may naturally emerge and can induce larger ratchet currents than low-order resonances, with the underlying classical limit being fully chaotic. The re...

OBJECTIVE To adapt and pilot test a multicomponent motivational intervention that includes family-based contingency management (CM) for adolescents with poorly controlled type 1 diabetes. METHODS A total of 17 adolescents, age 12-17 years (M = 14.8, SD = 1.5), with type 1 diabetes (duration M = 6.2 years, SD = 4.5) and mean HbA1c of 11.6% (SD = 2.5%) were enrolled. Adolescents and their paren...
