The Reinforcer Pathology theory proposes conditions under which drugs emerge as excessively preferred reinforcers compared to other available reinforcers among drug users. The theory highlights 2 key variables as important determinants of drug preference: (a) excessive preference for immediate rewards (high discounting of future rewards); and (b) excessive valuation for addictive reinforcers (e.g., drugs). Two iterations of the Reinforcer Pathology theory exist with the latest iteration (i.e., Reinforcer Pathology 2.0) specifying that the temporal window of reinforcer integration (measured by delay discounting) is a determinant of reinforcer value. The 2 iterations of the Reinforcer Pathology theory are described. A novel insight and understanding of abstinence and relapse from a Reinforcer Pathology perspective, limitations, and future directions are discussed. The Reinforcer Pathology theory continues the long-standing efforts to scientifically understand and better define novel concepts and methods to further translational research and improve treatment outcomes. Exploring the complementary relation between the Reinforcer Pathology perspective and other current approaches could have a valuable effect. 相似文献

An age-related decline in memory has been reported in male rats; however, there are few studies that have addressed these changes in aged female rats. In young female rats, hormonal cycles influence behavior. By the age of 22 months most female rats have not had regular hormonal cycles for at least 9 months. In the current study we examined how the hormonal status (persistent estrus and pseudo-pregnant) of the aged (22-24 months) female rat (Long Evans) influenced performance on a spatial version of the Morris water maze and compared this to aged male rats. Aged females in persistent estrus showed better performance on the water maze than both aged females that were pseudopregnant and aged males. Thus, postestropausal hormonal status may influence the course of aging in females. 相似文献

Reading can at times engage one emotionally and entail inner psychological experiences in ways akin to those in clinical psychoanalysis. In that light, after a general introduction regarding the import of reading, attention is turned to Proust, Freud's literary complement, as an exemplary instance to illustrate those similarities. Ideas of Proust on reading are followed by thoughts on reading Proust, with the ending of Proust's masterpiece used to illustrate a parallel to termination in clinical psychoanalytic experience. 相似文献
