The effects of dopaminergic drugs on morphine state-dependent memory of passive avoidance task were examined in mice. Pre-training administration of morphine (5mg/kg) led to state-dependent learning with impaired memory retrieval on the test day which was reversed by pre-test administration of the same dose of the opiate. The pre-test intracerebroventricular (i.c.v.) administration of the dopamine D1 receptor agonist (SKF38393), dopamine D2 receptor agonist (quinpirole) and dopamine D2 receptor antagonist (sulpiride) not only reversed the effect of pre-training morphine treatment, but also increased this action of the drug. Furthermore, the pre-test i.c.v. administration of dopamine D1 receptor antagonist (SCH23390) prevented the restoration of memory by morphine. In conclusion, the morphine-induced recovery of memory, on the test day, seems to be induced, at least in part, through dopamine receptors. 相似文献

There is growing evidence that Internet-mediated psychological tests can have satisfactory psychometric properties and can
measure the same constructs as traditional versions. However, equivalence cannot be taken for granted. The prospective memory
questionnaire (PMQ; Hannon, Adams, Harrington, Fries-Dias, & Gibson, 1995) was used in an on-line study exploring links between
drug use and memory (Rodgers et al., 2003). The PMQ has four factor-analytically derived subscales. In a large (N763) sample
tested via the Internet, only two factors could be recovered; the other two subscales were essentially meaningless. This demonstration
of nonequivalence underlines the importance of on-line test validation. Without examination of its psychometric properties,
one cannot be sure that a test administered via the Internet actually measures the intended construct. 相似文献

Since Kahneman and Tversky [(1979). Prospect theory: An analysis of decision under risk. Econometrica, 47, 263-291], it has been generally recognized that decision makers overweight low probabilities. Of the several weighting functions that have been proposed, that of Prelec [(1998). The probability weighting function. Econometrica, 60, 497-528] has the attractions that it is parsimonious, consistent with much of the available empirical evidence and has an axiomatic foundation. Luce [(2001). Reduction invariance and Prelec's weighting functions. Journal of Mathematical Psychology, 45, 167-179] provided a simpler derivation based on reduction invariance, rather than compound invariance of Prelec [(1998). The probability weighting function. Econometrica, 60, 497-528]. This note introduces a behavioral assumption that we call power invariance and provides a simple derivation of Prelec's function. Thus, we have three a priori different behavioral assumptions all leading to Prelec's function. 相似文献

In “Compassionate Phenomenal Conservatism” (2007), “Phenomenal Conservatism and the Internalist Intuition” (2006), and Skepticism and the Veil of Perception (2001), Michael Huemer endorses the principle of phenomenal conservatism, according to which appearances or seemings constitute a fundamental source of (defeasible) justification for belief. He claims that those who deny phenomenal conservatism, including classical foundationalists, are in a self-defeating position, for their views cannot be both true and justified; that classical foundationalists have difficulty accommodating false introspective beliefs; and that phenomenal conservatism is most faithful to the central internalist intuition. I argue that Huemer’s self-defeat argument fails, that classical foundationalism is able to accommodate fallible introspective beliefs, and that classical foundationalism has no difficulty accommodating a relatively clear internalist intuition. I also show that the motivation for phenomenal conservatism is less than clear. 相似文献

Partai Keadilan Sejahtera (PKS, The Justice and Prosperity Party) is the largest Islamist political party in Indonesia. It has roots in the religious and political and religious teachings of the Muslim Brotherhood and promotes what Oliver Roy calls "deculturized religion." The party can be understood as the political component of a larger social movement that seeks to transform Indonesian society and culture in ways that would establish Shari'ah as social, if not political, reality. It is also committed to the electoral process and to working inside the Indonesian political system in a more general sense. Until recently, the PKS has dismissed local modes of Muslim practice and much of Indonesian culture as "un-Islamic." The extent of the party's transformative agenda is unclear for three reasons: it shares the Muslim Brotherhood's gradualist approach, it is less than transparent about its goals, and it is divided into purist or "Justice" and pragmatic or "Prosperity" factions. The leadership of the Prosperity faction is currently ascendant and is attempting to reach beyond its Islamist base by sponsoring musical and dramatic performances it hopes will appeal to Muslims devoted to Javanese and other Indonesian cultural traditions. Ethnographic and web-based research indicate that these efforts are greeted with considerable suspicion. 相似文献

Object substitution masking (OSM) occurs when an initial display of a target and mask continues with the mask alone, creating a mismatch between the reentrant hypothesis, triggered by the initial display, and the ongoing low-level activity. We tested the proposition that the critical factor in OSM is not whether the mask remains in view after target offset, but whether the representation of the mask is sufficiently stronger than that of the target when the reentrant signal arrives. In Experiment 1, a variable interstimulus interval (ISI) was inserted between the initial display and the mask alone. The trailing mask was presumed to selectively boost the strength of the mask representation relative to that of the target. As predicted, OSM occurred at intermediate ISIs, at which the mask was presented before the arrival of the reentrant signal, creating a mismatch, but not at long ISIs, at which a comparison between the reentrant signal and the low-level activity had already been made. Experiment 2, conducted in dark-adapted viewing, ruled out the possibility that low-level inhibitory contour interactions (metacontrast masking) had played a significant role in Experiment 1. Metacontrast masking was further ruled out in Experiment 3, in which the masking contours were reduced to four small dots. We concluded that OSM does not depend on extended presentation of the mask alone, but on a mismatch between the reentrant signals and the ongoing activity at the lower level. The present results place constraints on estimates of the timing of reentrant signals involved in OSM. 相似文献

Report of a second target (T2) is impaired when presented within 500 ms of the first (T1). This attentional blink (AB) is known to cause a delay in T2 processing during which T2 must be stored in a labile memory buffer. We explored the buffer's characteristics using different types of masks after T2. These characteristics were inferred by determining what attributes of T2 are hindered by a given form of masking. In Experiments 1-3, trailing metacontrast and four-dot masks produced ABs of equal magnitudes, implicating the onset-transient triggered by the mask as the mechanism underlying the AB and strongly suggesting a locus in early vision. In Experiment 4, metacontrast and four-dot masks were presented in a common-onset masking (COM) paradigm in which a brief, combined display of T2 and the mask was followed by a longer display of the mask alone. COM is thought to occur late in the sequence of processing events. No AB occurred with COM, confirming the critical role of the mask's onset transients and ruling out a high-level locus for the labile memory buffer. 相似文献

The purpose of this study was to examine sexual self-esteem and perfectionism among Iranian women with and without overweight based on the role of age and education; and to investigate the relationships of sexual self-esteem, perfectionism, and body mass index in a sample of adult women. Participants were 200 women with and without overweight who were selected following a purposive sampling method from Shiraz City, Iran. A demographic questionnaire, Sexual Self-Esteem Inventory for Women (SSEI-W), and Perfectionism Inventory (PI) were used. Resulting data showed that women without overweight had higher total scores of sexual self-esteem and on the WWEI-W subscale of attractiveness compared with women who are overweight. Also, women who are overweight had higher total scores of perfectionism, as well as higher scores on subscales of interpersonal sensitivity and high standards for others compared to women without overweight. There was no significant effect for age and educational level on sexual self-esteem and perfectionism. The results demonstrated significantly negative relationships between overall sexual self-esteem, attractiveness subscale of sexual self-esteem, and body mass index. Also, the overall perfectionism and interpersonal sensitivity, striving for excellence, organization, and standards for others subscales of perfectionism had a significant positive relationship to the body mass index. 相似文献
