Knowing when to persevere with a plan and knowing when to ditch it and change strategy is highly adaptive and breaks down in several frontal and striatal disorders. Cognitive flexibility is also susceptible to tonic influences of neuromodulators (such as dopamine) and so may be influenced by everyday fluctuations in processes known to depend upon them (such as motivation). The current study employed an attentional shifting paradigm to examine the influence of changes in food-related motivational state in healthy volunteers. Hunger was induced through fasting (physiological manipulation) or through the presentation of appetitive food cues prior to testing (desire manipulation). The desire manipulation produced a stronger effect than fasting by inducing errors when participants were attempting to shift. The results suggest that everyday fluctuations in appetite and desire can produce a significant impact on cognition, highlighting implications for our understanding of excessive motivational control including maladaptive eating behaviour. 相似文献

HOW INVESTMENT IN GENDER IDEALS AFFECTS WELL-BEING: THE ROLE OF EXTERNAL CONTINGENCIES OF SELF-WORTH
The present study examined the relationship between investment in gender ideals and well-being and the role of external contingencies of self-worth in a longitudinal survey of 677 college freshmen. We propose a model of how investment in gender ideals affects external contingencies and the consequences for self-esteem, depression, and symptoms of disordered eating. Specifically, we find that the negative relationship between investment in gender ideals and well-being is mediated through externally contingent self-worth. The model showed a good fit for the overall sample. Comparative model testing revealed a good fit for men and women as well as White Americans, Asian Americans, and African Americans. 相似文献

This study compares the motivation and the quality of criticism responses of 697 undergraduates who were divided into three
levels of situation legitimacy (high, moderate, and low) and two levels (top versus bottom 40 percent) of anxiety related
to previous generalized assertiveness behaviours. The impact of gender was also studied. The results showed the legitimacy
of the situation for a critical response (preassessed with peer hold-out groups) significantly affected participants' motivation
to criticize as well as the quality of their critical responses, notwithstanding the poor quality of all criticism responses.
Anxiety related to previous global assertiveness was related to high motivation but not to quality of criticism responses.
There were no gender effects. Results are interpreted within an avoidance learning paradigm wherein the connotative meaning
of criticism is incongruent with harmonious long-term relationships so that it is suppressed until virtually forced by the
specifics of highly legitimate situations. 相似文献
