Emergent equivalence relations between interoceptive (drug) and exteroceptive (visual) stimuli. 下载免费PDF全文
R J DeGrandpre W K Bickel S T Higgins 《Journal of the experimental analysis of behavior》1992,58(1):9-18
Conditional "if-then" relations between drug (interoceptive) stimuli and visual (exteroceptive) stimuli were taught to 4 normal humans. Interoceptive stimuli were the effects produced by 0.32 mg/70 kg triazolam (a prototypical benzodiazepine) and placebo (lactose-filled capsules); exteroceptive stimuli were black symbols on white flash cards. Following the training of the prerequisite conditional relations, tests of emergent relations were conducted between exteroceptive stimuli and between interoceptive and exteroceptive stimuli. Equivalence relations emerged immediately without explicit training for all 4 subjects. Accuracy of responding during the interoceptive-exteroceptive equivalence tests and subjects' self-reports showed consistent discrimination between the drug effects of triazolam and placebo. Finally, a generalization test assessed whether a novel visual stimulus presented in the context of the placebo (i.e., no drug) would generalize to visual stimuli belonging to the placebo stimulus class. All 3 subjects who completed this test reliably chose the visual stimuli belonging to the placebo class and not the visual stimuli belonging to the triazolam stimulus class. The development of equivalence relations between interoceptive and exteroceptive stimuli demonstrates that private and public stimulus events can emerge as members of the same equivalence class. Theoretical and clinical implications are discussed. 相似文献

Adolescent and older mothers reported the size and quality of social networks and perceptions of family support at 1, 6, and 12 months postpartum. Maternal behavior, general life satisfaction, and parental satisfaction were assessed at 12 months. No significant differences were found in the size of social networks and quality of interactions within those networks, though older mothers had significantly higher scores on perceived family support than did adolescent mothers. Perceived family support and quality of interactions within the social network generally were associated positively with maternal behavior, life satisfaction, and parental satisfaction. This was true in more cases for the adolescent than for older mothers. 相似文献

The effects of diazepam and triazolam on repeated acquisition and performance of response sequences with an observing response. 下载免费PDF全文
W K Bickel S T Higgins J R Hughes 《Journal of the experimental analysis of behavior》1991,56(2):217-237
Drugs often disrupt the acquisition of new response sequences at doses that fail to disrupt the performance of a previously acquired response sequence. This selective drug effect may result from differences in the control exerted by the stimuli presented after each response in the acquisition and performance sequences. To examine the function of these stimuli, an observing procedure was incorporated into a multiple schedule of repeated acquisition and performance of response sequences, in which stimulus presentations were contingent upon an observing response. Three experiments were conducted with humans. Experiment 1 compared responding with and without the observing contingency. No difference was found in the overall percentage of errors across the two conditions. Within the observing condition, observing behaviour was maintained in the acquisition component as long as errors occurred, but was not maintained in the performance component. Experiment 2 examined whether a contingency that increased errors also would increase observing in both the acquisition and performance components. Specifically, reinforcer delivery in each component was contingent upon emitting 10 correct responses and one, two, or four errors. Observing responses increased in the acquisition component as the error requirement increased, whereas observing responses in the performance component increased only when the error requirement was four. Experiment 3 assessed the effects of diazepam (0, 7.5, 15, and 30 mg/70 kg, p.o.) and triazolam (0, 0.375, and 0.75 mg/70 kg, p.o.) on repeated acquisition and performance baselines with the observing contingency. Selective drug effects were obtained in this modified procedure; that is, the percentage of errors in the acquisition component increased at doses that failed to affect the percentage of errors in the performance components. Importantly, drug effects were selective, even though observing responses were not emitted in the performance component and, hence, the stimulus presentations did not occur in that component. These findings suggest that alternative explanations for these differential effects are needed; in that regard, a response-unit account of the selective drug effects is discussed. 相似文献

Memory errors occur when the context standard that is used when judging target behaviors is different from the category norm standard that is available later when the behaviors are recalled. Is insufficient awareness the reason for this change-of-standard effect? Two kinds of awareness were maximized in each of two studies: (a) awareness of the relation between the judgment and the context - telling subjects to be sure to use the non-target persons for comparison when judging the target person (salience); and (b) awareness at recall of the earlier judgmental context - asking subjects to recall the non-target persons before recalling the target person (reinstatement). Context reinstatement reduced memory errors. But when context reinstatement and salience were combined, the memory errors reappeared. In Study 2, an attempt at debiasing failed. The change-of-standard effect is explained in terms of a "natural" tendency to use the current categorical meaning of a judgment to reconstruct the referent of its past contextualized meaning. 相似文献

A behavioral economic analysis of concurrently available money and cigarettes. 总被引:1,自引:1,他引:0 下载免费PDF全文

In economic terms, consumption of a reinforcer is determined by its price and the availability and price of other reinforcers. This study examined the effects of response-requirement (i.e., price) manipulations on the self-administration of two concurrently available reinforcers. Six cigarette smokers participated in 4-hr sessions in which money and puffs on a cigarette were concurrently available according to fixed-ratio schedules of reinforcement. Once stable responding was obtained with both reinforcers available at Fixed Ratio 100, the response requirement for one reinforcer was systematically varied (Fixed Ratio 1,000 and 2,500), while the other reinforcer remained scheduled at Fixed Ratio 100. Increasing the fixed-ratio size for a reinforcer decreased its consumption, with a greater decrease occurring for monetary reinforcement. This finding was quantified in economic terms as own-price elasticity, with elasticity coefficients greater for money than cigarettes. The effects of fixed-ratio size on response output also differed across the two reinforcers. Although greater responding occurred for money at Fixed Ratio 100, increases in fixed-ratio size (for money) decreased responding for money, whereas the same increase in fixed-ratio size (for puffs) increased responding for puffs. Finally, increasing the fixed-ratio size for one reinforcer had little effect on consumption of the other concurrently available reinforcer. This finding was quantified as cross-price elasticity, with elasticity coefficients near 0.0 for most subjects, indicating little or no reinforcer interaction. The results indicate that the reinforcing effects of cigarettes and money in the setting studied here differed, and that the effects produced by changing the price of one reinforcer did not interact with the consumption of the other concurrently available reinforcer. 相似文献

For almost forty years gun ownership and the motivational underpinnings of why guns are valued has received little attention in psychology. Using motivation science tools that explain value creation (regulatory focus and regulatory fit), we tested for fit between the prevention orientation and gun ownership. Our field experiments demonstrate fit between gun ownership and prevention. Our research is agnostic regarding the legal and moral components of the gun rights debate. Instead, we examine the malleability of gun value as a function of regulatory focus and regulatory fit, and provide evidence for fit effects with distinct motivational environments. 相似文献

People are often motivated to reach self-serving conclusions during judgment. This article examines how such self-serving judgment outcomes are influenced by preferences for different judgment strategies. Two studies tested how preferences for eager (promotion-oriented) versus vigilant (prevention-oriented) judgment strategies affected self-serving explanations for success or failure. Regardless of their performance, those preferring vigilant strategies selectively endorsed a few explanations above others, whereas those preferring eager strategies more evenly endorsed multiple explanations. Furthermore, although the explanations selected by those preferring vigilant strategies were indeed self-serving (emphasizing personal responsibility for success and external circumstances for failure), the more balanced endorsement of multiple explanations by those preferring eager strategies was associated with attenuated self-serving tendencies. Finally, those preferring eager strategies were also less self-serving in their generalization from explanations of current performance to predictions of future performance. The larger implications of these findings for the role of strategic preferences in judgment are discussed. 相似文献

What is the relation between culture and personality? I argue that to address this question, it is necessary to meet five criteria: (1) to identify universal principles of human functioning that underlie both culture and personality; (2) to treat those principles at different levels of analysis for culture and personality; (3) to define culture and personality in terms of those principles in a manner that maintains the integrity of these concepts; (4) to select specific psychological factors that, because of their survival value, are present in every culture and individual, although to varying degrees; and (5) to postulate how different cultures and personalities emerge from variability in the predominance of those specific psychological factors. I then propose that these criteria can be met by identifying specific human motives that are both universal and vary across individuals, situations, and groups. I propose a five‐step model that describes how cultures influence the personalities that emerge among its members, with particular emphasis on the human‐defining period of development between 3 and 6 years of age, and how those personalities in turn influence the culture (from effects of regulatory fit). As initial support for the model, evidence is reviewed for commonality among cultures in the existence of promotion, prevention, locomotion, and assessment motives; for variability across cultures in the predominance of these motives as modal personalities; and for universality in the relations between each motive and Big Five and self‐esteem trait characteristics. Combining the latter universal relations with the cultural variability in modal personalities yields cultural differences in manners of goal pursuit. 相似文献

We examined the effect of competition on briefly thinking of just-seen items. In Experiment 1, participants saw a set of either
three related or three unrelated words and then read one of the words again (repeat) or thought briefly of one of the words
(refresh). Participants read the set a second time, after which they either refreshed a second word from the set or read a
new word. In comparison with reading a new word, response times were slower for refreshing the second item when participants
had just refreshed than when they had just repeated the first item. This increase was larger for related words than for unrelated
words and for older adults than for younger adults. In Experiment 2, a negative impact of refreshing was observed when participants
repeated a different word from the set. The pattern of findings suggests that the negative impact of refreshing comes from
increased competition from the refreshed item, rather than from inhibition of the nonrefreshed items. 相似文献
