The capacity to attribute meaning to personal experiences may rest on a specialized cognitive system enabling this form of causal reasoning. Close examination of these attributional tendencies suggests that this system may be distinct from those underlying other forms of causal reasoning such as a “theory of mind” system in the behavioral domain, a folk physics system in the physical domain, and a folk biology system in the biological domain. A fourth, existential domain, an abstract ontological frame within which the subjective, narrative self is envisioned to be contained, may have driven the construction of an intuitive capacity in humans that encourages them to search for the underlying purpose or reason for having had certain life experiences. This system likely has specific, definable operational rules that are responsible for activating such explanatory searches. In addition, it appears anchored to a general intentionality system that promotes the attribution of teleological purpose and higher-order mental states to an abstract agency that is envisioned to cause events and personal experiences. Identifying the component parts of this specialized cognitive system through empirical investigations can help researchers to reconstruct both its evolutionary phylogeny and to track its developmental emergence.  相似文献

Many drugs of abuse produce changes in impulsive choice, that is, choice for a smaller—sooner reinforcer over a larger—later reinforcer. Because the alternatives differ in both delay and amount, it is not clear whether these drug effects are due to the differences in reinforcer delay or amount. To isolate the effects of delay, we used a titrating delay procedure. In phase 1, 9 rats made discrete choices between variable delays (1 or 19 s, equal probability of each) and a delay to a single food pellet. The computer titrated the delay to a single food pellet until the rats were indifferent between the two options. This indifference delay was used as the starting value for the titrating delay for all future sessions. We next evaluated the acute effects of nicotine (subcutaneous 1.0, 0.3, 0.1, and 0.03 mg/kg) on choice. If nicotine increases delay discounting, it should have increased preference for the variable delay. Instead, nicotine had very little effect on choice. In a second phase, the titrated delay alternative produced three food pellets instead of one, which was again produced by the variable delay (1 s or 19 s) alternative. Under this procedure, nicotine increased preference for the one pellet alternative. Nicotine‐induced changes in impulsive choice are therefore likely due to differences in reinforcer amount rather than differences in reinforcer delay. In addition, it may be necessary to include an amount sensitivity parameter in any mathematical model of choice when the alternatives differ in reinforcer amount.  相似文献

This study examines the prevalence of endorsing the twelve step approach and the use of prayer, meditation, and holistic techniques in a national sample of 139 substance abuse treatment centers. Ninety one percent of the programs endorsed a twelve step orientation. Twenty six percent of the programs actively used prayer and 58% used meditation as a component of treatment. Thirty three percent of the programs used some form of a self-designated holistic technique. There was a divergent range of techniques that were used by programs, falling into four broad categories: (1) nutrition, exercise, relaxation and physical health; (2) recreation and adventure-based activities; (3) religious and spiritual practices; and (4) the use of specific therapy modalities.  相似文献

In this paper, we will present a case history of a disabled network which includes a multiproblem family and the social service agencies serving it. We will describe a five-step model for effective intervention into the entire system. Social service agents frequently become overwhelmed and therefore impotent in their attempts to help multiproblem families. In such cases, agents reflect the family's dysfunction by becoming dysfunctional themselves and their actions serve to increase the family's alienation from its community by reinforcing its stigmatized self-image. Our model focuses on building boundaries and creating hierarchies which encourage individuation within the family and empowers the network to effectively meet family needs.  相似文献

To date, marriage and family therapy does not have formal socialization programs at the undergraduate level. Socialization activities may include career classes, advising, providing internships, or actively recruiting the most talented and qualified students. These socialization activities may also aid in the recruitment of minority students. A survey of the accredited programs revealed that most programs do not have formal opportunities for the faculty to interact and discuss therapy as a career option. While most programs have at least one faculty member who teaches undergraduates, this contact alone is not very good in terms of socializing students into choosing therapy as a career option. While there are some valid concerns about undergraduates, marriage and family therapy as a distinct discipline may benefit from actively recruiting the best students.  相似文献

Children ages 3-9 years were informed that an invisible agent (Princess Alice) would help them play a forced-choice game by "telling them, somehow, when they chose the wrong box," whereas a matched control group of children were not given this supernatural prime. On 2 unexpected event trials, an experimenter triggered a simulated unexpected event (i.e., a light turning on/off; a picture falling), and children's behavioral response to these events (i.e., moving their hand to the opposite box) was coded. Results showed a significant Age GroupxExperimental Condition interaction; the only children to reliably alter their behavior in response to the unexpected events were the oldest children (M=7 years 4 months), who were primed with the invisible agent concept. For children's posttest verbal explanations, also, only these children saw the unexpected events as being referential and declarative (e.g., "Princess Alice did it because I chose the wrong box"). Together, these data suggest that children may not regularly begin to see communicative signs as embedded in unexpected events until they are around 7 years of age.  相似文献

The prawn-in-a-tube procedure (J. B. Messenger, 1973a) has been used almost exclusively to study associative learning in cuttlefish. In two experiments, the authors sought to determine whether the decline in attack responses observed in this procedure was best accounted for by habituation or associative learning. Results of Experiment 1 revealed an asymmetrical stimulus-specificity effect that could be interpreted as either an instance of habituation or of associative learning. Results of Experiment 2 demonstrated that the response decline could not be reversed following the presentation of a dishabituatory stimulus. The combined results of these experiments support the conclusion that the response decline is best viewed as a resulting of associative processes. The authors considered whether the response decline represents extinction or passive avoidance.  相似文献

Atherosclerotic disease accounts for approximately 25% of ischemic strokes. Atherosclerotic stroke is caused mainly by embolic events from the carotid artery bifurcation or the aortic arch, although intracranial thrombosis can occur, more often in African Americans, Asians, and diabetes patients. Primary prevention of stroke is critical for patients with risk factors for atherosclerosis, including hypertension, diabetes, smoking and hypercholesterolemia. Stroke can be prevented in patients with established atherosclerotic disease by identification and management of patients with carotid artery stenosis by non-invasive testing. Particular attention must be paid to patients with transient symptoms of brain ischemia.  相似文献

Recent scholarship has conceptualized morality in terms of multidimensional, intuitive traits that influence what people regard as right or wrong. Ample literature shows that religious factors are closely related to moral traits. However, little research has explored links between religious upbringing and adult moral outcomes. This study uses longitudinal data from the National Study of Youth and Religion to examine how diverse forms of religious socialization in adolescence are related to two well-validated social-scientific conceptions of morality in young adulthood: Haidt's moral foundations and Schwartz’ values typology. Using regression analyses and Lindeman, Merenda, and Gold (LMG) decomposition methods, I show that different aspects of religious upbringing are linked to the development of both moral foundations and values. Religious factors play a stronger role than either sociodemographics or parent political ideology in predicting young adult moral characteristics. Results highlight the centrality of religious upbringing to the state and trajectory of the population-level moral structure.  相似文献
