This paper presents six; principles of laboratory organization and design. These six principles are an outgrowth of the past 7 years’ experience in the Mathematical Models Laboratory of the Psychology Department at Indiana University. Each of the six principles is formally stated and then followed by explanation and examples. 相似文献

This article provides a rationale for research on personality as a contributing factor in the development of physical disease. A brief history of major developments from the 1930s to the present is then provided. Special attention is given to shifts in conception regarding whether particular dispositions are related to specific physical disorders or whether these dispositions increase general illness susceptibility. The paper ends with a brief orientation to the other papers and commentaries in this special issue. 相似文献

This study examines the relationships between locus of control expectancies, rated health value, and reported participation in preventive health behaviors among a healthy sample of undergraduate women. The prediction that participation in preventive health behaviors would be a joint function of an internal health-related locus of control belief and holding health in high value was not supported. Instead, individuals who valued their health reported participating in a greater number of health-enhancing behaviors compared to those who valued their health less. Respondents' scores on a health value scale in combination with their rated health status proved to be better predictors of health behaviors than their locus of control beliefs. Limitations of locus of control research with young, healthy individuals are discussed and further investigation into the utility and validity of health value scales is recommended. 相似文献

Following 25 years of landmark progress, health psychology faces even greater change in the foreseeable future. Evolving patterns of health and illness and developments in medicine and related fields will shape the future of health psychology. The articles in this special section discuss these future issues in several areas: the biopsychosocial model, changes in demographics, prevention, clinical health psychology interventions, health care financing, and new technologies. In every case, the future holds a variety of important challenges and opportunities in research, practice, training, and policy. 相似文献

People are inherently driven by the need to form and maintain relationships, and these affiliation goals can influence health behaviors in two ways: (a) indirectly, by increasing a person's attention to others and subsequently leaving them more likely to emulate the health behaviors of others (social contagion); (b) directly, by leading people to be more likely to engage in health behaviors they perceive as helping them to form and maintain relationships with others (self-initiated behavioral engagement). In this review, we discuss the evidence for the catalyzing role of affiliation goals in these two processes for a variety of positive (e.g., exercising, smoking-cessation) and detrimental health behaviors (e.g., binge drinking and eating, needle sharing). Additionally, we discuss individual difference factors that may temporarily or chronically activate affiliation goals and ultimately impact health behaviors. Affiliation goals hold many implications for future work, and for improving interventions. 相似文献

Although the Morris water task has been used in hundreds of studies of place learning, there have been no systematic studies of retention of the place memory. We report that retention, as measured by selective search behavior on a probe trial, is excellent when the retention interval is short (5-10 min). However, performance rapidly deteriorates, so that by approximately 4 h the search is no longer selective. Additional experiments revealed that selective search at longer retention intervals was improved by inserting gaps between blocks of training trials, but this effect was a non-monotonic function of the interval separating trial blocks. Our experiments also revealed that the location of the first block of trials (Room A or Room B) was irrelevant to long-term retention. A memory modulation theoretical framework may provide a useful way to understand these findings. 相似文献

We report that post-training inactivation of basolateral amygdala region (BLA) with muscimol impaired memory for contextual-fear conditioning (as measured by freezing) and intra-BLA norepinephrine enhanced this memory. However, pre-exposure to the context eliminated both of these effects. These findings provide a likely explanation of why an earler study failed to observe that the BLA modulates contextual fear conditioning-they pre-exposed their rats to the context. These results also suggest that the amygdala modulates the storage of the context fear memory and may do so by influencing the storage of the representation of the context in which the shock occurred. 相似文献

We use a variation of contextual fear conditioning, called the context pre-exposure facilitation effect (CPFE) to study the rat's memory for context. In this paradigm, the rat is pre-exposed to a conditioning context and later returned to that context, where it is immediately shocked. The memory context is revealed by the fact that pre-exposure to the conditioning context, but not to a different context, greatly enhances conditioned fear produced by immediate shock. We report that rat's retention of the context memory is a nonmonotonic U-shaped function of the interval separating pre-exposure and immediate shock. Retention performance decays rapidly so that within 2 min of pre-exposure there is no evidence that the rat was pre-exposed to the context. Within a few hours, however, a strong CPFE was observed that persisted for at least 28 d. Two hypotheses are discussed: (1) the descending arm of the U represents a retrieval failure, and (2) the U-shaped function represents two discontinuous memory processes initiated in parallel-short-term synaptic changes that are rapidly initiated, but also decay rapidly, and long-term synaptic processes that take time to generate but can endure for days. 相似文献

Three studies investigated the role of nonmotivated egocentric processes in comparative optimism (and pessimism). According to an egocentric-processes account, when people judge their comparative likelihood of experiencing an event (e.g., "Compared to the average person, how likely are you to become wealthy?"), they consider their own chances of experiencing the event more so than the referent's chances. This should produce higher comparative estimates when an event's absolute frequency is high rather than low-a prediction supported in Study 1, which manipulated event frequency through a novel, time frame manipulation. Study 2 empirically distinguished egocentrism from a related focalism account. In Study 3, comparative estimates were related to the perceived frequency of events, independent of the events' perceived desirability and controllability. Path analyses provided additional support for egocentrism, and systematic cases of comparative pessimism were observed as predicted by the egocentric-processes account. 相似文献
