Reformers urge that representation no longer earns its explanatory keep in cognitive science, and that it is time to discard
this troublesome concept. In contrast, we hold that without representation cognitive science is utterly bereft of tools for
explaining natural intelligence. In order to defend the latter position, we focus on the explanatory role of representation
in computation. We examine how the methods of digital and analog computation are used to model a relatively simple target
system, and show that representation plays an in-eliminable explanatory role in both cases. We conclude that, to the extent
that biologic systems engage in computation, representation is destined to play an explanatory role in cognitive science.

Emotion regulation may influence psychological responses to exercise. We examined whether the emotion regulation strategies, cognitive reappraisal and distraction, influenced psychological state and prefrontal cortex oxygenation during endurance exercise. Twenty-four endurance runners ran for 90 min at 75–85% maximum heart rate in three separate sessions with no instruction or with instructions to use cognitive reappraisal or distraction. Participants rated their emotional arousal, emotional valence, and perceived exertion before, every 30 min during, and after exercise. Functional near-infrared spectroscopy quantified changes in prefrontal cortex oxygenation. Participants felt lower emotional arousal and physical exertion when instructed to utilize cognitive reappraisal than when given no emotion regulation instruction. Such responses to distraction did not differ from the other conditions. Emotion regulation strategies did not influence emotional valence or prefrontal cortex oxygenation. Participants’ analytical interpretation of the cognitive reappraisal instruction could contribute to small effect sizes and limited effects. Further research should determine contexts under which emotion regulation strategies most benefit endurance exercise experience. 相似文献

Researchers have identified difficulties associated with the use of traditional Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) validity scales with survivors of traumatic events. A new scale, the Infrequency-Posttraumatic Stress Disorder scale (Fptsd), was created from MMPI-2 items that were infrequently endorsed by 940 male combat veterans presenting for treatment at the posttraumatic stress disorder (PTSD) clinics of 2 Veterans Affairs Medical Centers. A variety of statistical methods were implemented that preliminarily established Fptsd's validity with a validation sample of 323 additional PTSD-diagnosed combat veterans. Results indicate that, relative to previously established validity and overreporting scales (F, Fb, and Fp), Fptsd was significantly less related to psychopathology and distress and better at discriminating simulated from genuinely reported PTSD. Clinical implications are discussed concerning the use of Fptsd to assess disability-seeking veterans suspected of overreporting PTSD symptoms. 相似文献

Relatively little research has been conducted on the relationship between alcohol misuse and suicidal behavior among the elderly. The current study's aim was to examine whether quantity and frequency of alcohol use and the interaction between these variables are related to current suicidal ideation, previous suicidal ideation/intent, and past suicide attempts in a community sample of 1,010 Australian adults over age 60. Results partially supported our hypotheses. The interaction between quantity and frequency of alcohol use was significant, suggesting that those who use alcohol less frequently but in greater quantities (i.e., binge drinking) are more likely to have a history of suicide attempts. 相似文献
