Pigeon and human subjects were given repeated choices between variable and adjusting delays to token reinforcement that titrated in relation to a subject's recent choice patterns. Indifference curves were generated under two different procedures: immediate exchange, in which a token earned during each trial was exchanged immediately for access to the terminal reinforcer (food for pigeons, video clips for humans), and delayed exchange, in which tokens accumulated and were exchanged after 11 trials. The former was designed as an analogue of procedures typically used with nonhuman subjects, the latter as an analogue to procedures typically used with human participants. Under both procedure types, different variable‐delay schedules were manipulated systematically across conditions in ways that altered the reinforcer immediacy of the risky option. Under immediate‐exchange conditions, both humans and pigeons consistently preferred the variable delay, and indifference points were generally ordered in relation to relative reinforcer immediacies. Such risk sensitivity was greatly reduced under delayed‐exchange conditions. Choice and trial‐initiation response latencies varied directly with indifference points, suggesting that local analyses may provide useful ancillary measures of reinforcer value. On the whole, the results indicate that modifying procedural features brings choices of pigeons and humans into better accord, and that human—nonhuman differences on risky choice procedures reported in the literature may be at least partly a product of procedural differences.  相似文献

This paper is based on interviews with users of a drop‐in centre run by a voluntary group. Using a grounded theory approach the paper argues that individuals' use of the drop‐in is linked to the discursive strategies that they have developed to cope with stigma. Tajfel's Social Identity Theory is employed as a framework to examine how users manage the threat to their identity posed by the diagnosis and experience of mental illness. The implications of this research are examined within the context of the empowerment paradigm of mental health. Copyright © 2001 John Wiley & Sons, Ltd.  相似文献

Do professional ethicists behave any morally better than other professors do? Do they show any greater consistency between their normative attitudes and their behavior? In response to a survey question, a large majority of professors (83 percent of ethicists, 83 percent of nonethicist philosophers, and 85 percent of nonphilosophers) expressed the view that “not consistently responding to student e‐mails” is morally bad. A similarly large majority of professors claimed to respond to at least 95 percent of student e‐mails. These professors, and others, were sent three e‐mails designed to look like queries from students. Ethicists’ e‐mail response rates were not significantly different from the other two groups’. Expressed normative view correlated with self‐estimated rate of e‐mail responsiveness, especially among the ethicists. Empirically measured e‐mail responsiveness, however, was at best weakly correlated with self‐estimated e‐mail responsiveness; and professors’ expressed normative attitude was not significantly correlated with empirically measured e‐mail responsiveness for any of the three groups.  相似文献

Eastern religions, such as Hinduism and Buddhism, have traditionally held to the view that in order for an individual to fully benefit from their practice it was important to lessen or eliminate one's individual desires. Such practice was sometimes referred to as the “death of the ego” in order to emphasize its importance. However, the relatively recent popularity of East‐meets‐West spirituality in Western consumer cultures tends to emphasize the acceptance and transformation of one's ego rather than its death. This essay discusses sociological changes that have shaped and contributed to the popularity of East‐meets‐West spirituality in Western culture that in turn have brought about a modification of the principle of ego death. The views of six Western authors and practitioners of East‐meets‐West spirituality on the importance of the principle of ego death are compared and contrasted. Theories related to the management of self‐identity in consumer society can partly explain the modification of traditional Eastern religious practices, such as ego death, in order that they become relevant and appealing to a society that increasingly reifies the concept of the self. The implication is that the excision of the concept of ego death from the practice of East‐meets‐West spirituality may affect its efficacy.  相似文献

The present study used within‐session transitions between two concurrent schedules to evaluate choice in transition. Eight female Long‐Evans rats were trained to respond under concurrent schedules of reinforcement during experimental sessions that lasted 22 hr. The generalized matching equation was used to model steady‐state behavior at the end of each session, while transitional behavior that emerged following the change in reinforcement schedules was modeled using a logistic equation. The generalized matching and logistic equations were appropriate models for behavior generated during single‐session transitions. A local analysis of behavior on the two response alternatives during acquisition was used to determine the source of preference as revealed in response ratios. The number of “low‐response” visits, those containing three to five responses, remained stable. Preference ratios largely reflected a sharp increase in the number of visits with long response bouts on the rich alternative and a decrease in the number of such visits to the leaner alternative.  相似文献

In three studies, we examine the mental accounting rules that govern how gift cards are used. We predicted that their identity as gift cards would shift consumption from utilitarian to hedonic goods even in contexts where both types of goods are available and the consumer's needs are unchanged. In Study 1a, participants were asked to imagine that they had both a gift card and a specified amount of cash and needed to purchase both a hedonic item and a utilitarian item. When asked which currency they would use to buy which item, respondents were significantly more likely to say they would use the gift card to buy the hedonic item. Study 1b replicated this result and found that it was tied to participants' beliefs how different types of money should be used. In Study 2, we found that participants who were required to spend a certain amount of their compensation in a laboratory store spent more on hedonic goods if their payment was in the form of a gift card. In Study 3, we analyzed transactions at a campus bookstore and found that shoppers tended to spend disproportionately on hedonic goods when using their gift cards than when making credit card purchases. Taken together, these studies indicate that people tend to assign the monetary value of a gift card to a hedonic mental account and spend it accordingly.

We examined self‐ and cross‐citations in the Journal of Applied Behavior Analysis (JABA) and the Journal of the Experimental Analysis of Behavior (JEAB) from 2004 through 2018. Mean annual levels of self‐citations for JABA and JEAB were 40.1% and 28.7%, respectively. Overall, 5.1% of JABA citations were JEAB articles, and 2.3% of JEAB citations were JABA articles. Although overall cross‐citation levels were relatively low, 28.7% of the JABA articles reviewed had at least one JEAB citation, and 27.5% of the JEAB articles reviewed had at least one JABA citation. Authors in both journals cited articles addressing the topics of matching and motivating operations. The extent to which the basic and applied sectors of behavior analysis interact depends on how the interaction is measured. Nonetheless, the degree of interaction is growing, which is a good thing for the discipline.  相似文献

Fixed‐time (FT) schedules of reinforcement have been used to decrease destructive behavior. However, the effects of FT schedules on acquisition and maintenance of appropriate behavior remain unclear. In this study, we present a case in which an FT schedule produced an increase in adaptive behavior and resulted in a significant decrease in destructive behavior.  相似文献

In Creation and the World of Science (1979) scientist‐theologian Arthur Peacocke asks what the role of humanity might be in relation to creation if conceived within the scientific perspective that favors the theological paradigm of the panentheistic God‐world relationship. Deeming roles such as dominion and steward as liable to distortion toward a hierarchical understanding of humanity's relation to the rest of creation, Peacocke proposes seven other roles to express the proper relationship of humanity to the cosmos in panentheistic relation to its Creator. Although each of these models has merit within a panentheistic paradigm, Peacocke and the paradigm itself suggest that the panentheistic model of God in relation to an evolving cosmos may be most effectively imaged through a model of female procreativity. In keeping with this proposal, I develop the understanding of humanity's ecologically ethical role in relation to the evolving cosmos in terms of the midwife to the process of procreation. I evaluate the efficacy of the midwife as a paradigm for ecological ethics by means of several criteria, including the propositions of the Earth Charter, “a declaration of fundamental principles for building a just, sustainable, and peaceful global society in the 21st century” (Earth Initiative 2000).  相似文献

The present research investigates how incidental confidence influences self‐interested behaviors. It is well established that being in a psychological state of lower confidence causes people to experience psychological aversion that they are motivated to reduce. We study the transfer effect of confidence; people strive to compensate for lower confidence in one domain by obtaining higher status in other unrelated domains. Prior research has linked money with status and suggested that money can increase confidence. Building on this research, we proposed and showed in four experiments that lower incidental confidence increased self‐interested behaviors that brought financial gains. Drawing on research on competitive altruism, we also predicted and found that when altruism, rather than money, was seen as the primary source of status, the effect of incidental confidence reversed such that lower incidental confidence decreased self‐interested behaviors. Data ruled out alternative explanations and provided consistent evidence for the proposed compensatory mechanism. We also discussed theoretical and practical implications of the present research.

We may understand natural science as part of the attempt by human beings to understand themselves and their place in the world in which they find themselves. In this sense, as Karl Rahner has suggested, natural science flows naturally into anthropology. Consciously or unconsciously, science is always part of the drive to self‐understanding. In an age of religious pluralism like ours, Christian faith in Asia is also brought face to face with the living reality of other religions, and that, too, cannot but affect how we understand our shared humanity.  相似文献

The in‐group preference and self‐concepts of urban Aboriginal‐Australian and Anglo‐Australian children have never been compared, nor their relationships to teachers' evaluations of academic performance. In this study, 60 Aboriginal (primarily local Nyoongah) and 60 Anglo children aged 6–12 years were tested on in‐group preference; children aged 8+ were tested on self‐concept. Also, their teachers evaluated them on their general academic performance. Results indicated that Anglo children showed greater in‐group preference and scored higher on teacher evaluations than Aboriginal children, although there was no difference on self‐concept. No correlation existed between in‐group preference and self‐concept. It was concluded that the problems faced by Aboriginal children are only likely to be alleviated by a great deal of structural change. Copyright © 2000 John Wiley & Sons, Ltd.  相似文献

Few studies have explored the effects of fixed‐time (FT) reinforcement on escape‐maintained behavior of students in a classroom setting. We measured the effects of an FT schedule on the disruptive and appropriate academic behaviors of 2 junior high students in a public school setting. Results demonstrated that FT escape from tasks resulted in a substantial decrease in disruptive behavior and an increase in time engaged in tasks for both participants.  相似文献

While there is evidence from the self‐determination perspective for the mediation of basic needs satisfaction in the materialism–well‐being link, no research to date has attempted to examine the relative contribution of the three needs to the mediating effect. Given that the predictive value of psychological needs on well‐being depends upon the match between the need and life domains, in two studies we investigate the differential mediating role of all three needs in the negative relationship between materialism and well‐being. In study 1, 231 adult participants self‐reported their materialistic attitudes, basic needs satisfaction and well‐being. In study 2 (N = 82 undergraduates), we experimentally activated materialistic thoughts and examined their effects on need satisfaction and state well‐being as compared to a neutral control condition. Study 1 furnished cross‐sectional evidence that materialism diminishes well‐being through lower satisfaction of the psychological need for autonomy only. Study 2 showed that experimental activation of materialism via short‐term exposure to pictorial consumer‐cues leads to lower satisfaction of the need for autonomy, which in turn produces higher negative affect among participants. The findings point towards the importance of considering the specific role of the psychological need for autonomy in the materialism–well‐being link.  相似文献

In the United States, the demand for child mental health services is increasing, while the supply is limited by workforce shortages. These shortages are unlikely to be corrected without significant structural changes in how mental health services are provided. One strategy for bridging this gap is task‐shifting, defined as a process by which services that are typically delivered by professionals are moved to individuals with less extensive qualifications or training. Although task‐shifting can increase the size of the workforce, there are challenges related to training new workers. In this paper, we propose Just‐In‐Time Training (JITT) as one strategy for improving task‐shifting efforts. We define JITT as on‐demand training experiences that only include what is necessary, when it is necessary, to promote competent service delivery. We offer a proof of concept from our own work shifting counseling and academic support tasks from school mental health professionals to pre‐baccalaureate mentors, citing lessons learned during our iterative process of JITT development. We conclude with a series of key considerations for scaling up the pairing of task‐shifting and JITT, including expanding the science of JITT and anticipating how task‐shifting and JITT would work within the context of dynamic mental health service systems.  相似文献

The use of differential reinforcement of other behavior (DRO) has decreased, at least partially due to the development of less effortful alternative behavioral interventions (e.g., noncontingent reinforcement; Vollmer, Iwata, Zarcone, Smith, & Mazaleski, 1993). The effort associated with DRO contingencies may be lessened by incorporating self‐monitoring components in which clients are responsible for the delivery of reinforcers for their own behavior. The current study evaluates the effectiveness of DRO in the treatment of self‐injury when implemented first by the therapist and subsequently by the client.  相似文献

Identification With All Humanity (IWAH) relates to higher levels of concern and supportive behavior toward the disadvantaged, stronger endorsement of human rights, and stronger responses in favor of global harmony. So far, IWAH has been conceptualized as a one‐dimensional construct describing the degree with which one identifies with all humans as a superordinate ingroup. However, recent group identification models suggest a multi‐dimensional model to provide a more differentiated approach toward the understanding of the highest level of social identification. Using principal axis (Study 1) and confirmatory (Study 2) factor analyses, we suggest that IWAH sub‐divides into two dimensions—global self‐definition and global self‐investment. Study 2 revealed that global self‐investment was a stronger predictor for both convergent measures (e.g., social dominance orientation and authoritarianism) and behavioral intentions than global self‐definition. Finally, in Study 3, we manipulated IWAH to test its causal effect on donation behavior. Participants in the experimental condition, compared with the control condition, showed higher global self‐investment, which in turn predicted greater giving to global charity. These findings suggest that two dimensions with different behavioral outcomes underlie IWAH.  相似文献
