In this study, we focus on the conditions which permit people to assert a conditional statement of the form 'if p then q' with conversational relevance. In a broadly decision-theoretic approach, also drawing on hypothetical thinking theory [Evans, J. St. B. T. (2007). Hypothetical thinking: Dual processes in reasoning and judgement. Hove, UK: Psychology Press.], we predicted that conditional tips and promises would appear more useful and persuasive and be more likely to encourage an action p when (a) the conditional link from p to q was stronger, (b) the cost of the action p was lower and (c) the benefit of the consequence q was higher. Similarly, we predicted that conditional warnings and threats would be seen as more useful and persuasive and more likely to discourage an action p when (a) the conditional link from p to q was stronger, (b) the benefit of the action p was lower and (c) the cost of the consequence q was higher. All predictions were strongly confirmed, suggesting that such conditionals may best be asserted when they are of high relevance to the goals of the listener. 相似文献

Participants were trained and tested to select stimuli of differing physical quantities in the presence of 2 color contextual cues for more than and less than. Following more than and less than relational training, participants allocated the majority of their responses to the slot machine that shared formal properties of color with the contextual cue for more than, despite the identical payout probabilities of the slot machines. 相似文献

This study examines how traditionality influences the relationships between job stressors and health. A sample of 496 Chinese employees provided longitudinal questionnaire data, and their health was assessed by collecting blood samples and monitoring blood pressure. The results indicated that the positive relationship between job control and health was stronger among the less traditional workers, whereas the positive relationship between distributive justice and health was stronger among the more traditional workers. Furthermore, traditionality moderated the interactive effects of job demands and perceived control/justice on health. Perceiving higher control mitigated the effects of job demands on upper respiratory infections among low traditionalists, but it exacerbated the effects among the high traditionalists. Perceptions of higher justice mitigated the effects of job demands on emotional exhaustion and immunoglobulin A for high traditionalists but not for low traditionalists. These results suggest that, in the relationship between job demands and psychological and physiological health, concern for equity is an important moderator for individuals with more traditional values, whereas perceived personal control is salutary for health primarily among people with less traditional values. 相似文献

It has been suggested that the central and peripheral neural processes (CPNP) are affected by gravitational changes. Based on the previous experiments during parabolic flights, central and peripheral changes may not only be due to the changed gravitational forces but also due to neuroendocrine reactions related to the psycho-physiological consequences of gravitational changes. The present study focuses on the interaction of neuroendocrine changes and the physical and mental states after acceleration to three-time terrestrial gravity (3Gz). Eleven participants (29.4+/-5.1 [SD] years (male (n=8): 30+/-5.1 years; female (n=3): 27.7+/-2.1 years) underwent a 15 min acceleration to 3Gz in a human centrifuge. Before and after the acceleration to 3Gz circulating stress hormone concentrations (cortisol, adrenocorticotropic hormone (ACTH), prolactin, epinephrine, norepinephrine) and perceived physical and mental states were recorded. A second control group of 11 participants underwent the same testing procedure in a laboratory session. Serum cortisol concentration during exposure to the centrifugal acceleration increased by 70%, plasma concentration of ACTH increased threefold, prolactin twofold, epinephrine by 70% and norepinephrine by 45%, whereas the perceived physical well-being decreased. These findings demonstrate that psycho-physiological changes have to be regarded as a relevant factor for the changes in CPNP during phases of hypergravity exposure. 相似文献

Hierarchical (or multilevel) statistical models have become increasingly popular in psychology in the last few years. In this article, we consider the application of multilevel modeling to the ex-Gaussian, a popular model of response times. We compare single-level and hierarchical methods for estimation of the parameters of ex-Gaussian distributions. In addition, for each approach, we compare maximum likelihood estimation with Bayesian estimation. A set of simulations and analyses of parameter recovery show that although all methods perform adequately well, hierarchical methods are better able to recover the parameters of the ex-Gaussian, by reducing variability in the recovered parameters. At each level, little overall difference was observed between the maximum likelihood and Bayesian methods. 相似文献

Cocaine addiction is associated with long-term cognitive alterations including deficits on tests of declarative/spatial learning and memory. To determine the extent to which cocaine exposure plays a causative role in these deficits, adult male Long-Evans rats were given daily injections of cocaine (30 mg/kg/day x 14 days) or saline vehicle. Three months later, rats were trained for 6 sessions on a Morris water maze protocol adapted from Gallagher, Burwell, and Burchinal [Gallagher, M., Burwell, R., & Burchinal, M. (1993). Severity of spatial learning impairment in aging: development of a learning index for performance in the Morris water maze. Behavioral Neuroscience, 107, 618-626]. Rats given prior cocaine exposure performed similarly to controls on training trials, but searched farther from the platform location on probe trials interpolated throughout the training sessions and showed increased thigmotaxis. The results demonstrate that a regimen of cocaine exposure can impair Morris water maze performance as long as 3 months after exposure. Although the impairments were not consistent with major deficits in spatial learning and memory, they may have resulted from cocaine-induced increases in stress responsiveness and/or anxiety. Increased stress and anxiety would be expected to increase thigmotaxis as well as cause impairments in searching for the platform location, possibly through actions on ventral striatal dopamine signaling. 相似文献

A common view of the relation between oughts and reasons is that you ought to do something if and only if that is what you
have most reason to do. One challenge to this comes from what Jonathan Dancy calls ‘enticing reasons.’ Dancy argues that enticing
reasons never contribute to oughts and that it is false that if the only reasons in play are enticing reasons then you ought
to do what you have most reason to do. After explaining how enticing reasons supposedly work and why accepting them may appear
attractive, I firstly show why we are not committed to accepting them into our conceptual framework and then argue that no
reasons work in the way enticing reasons are claimed to. Thus we should reject the category of enticing reasons entirely.

John Perry has argued that language, thought and experience often contain unarticulated constituents. I argue that this idea
holds the key to explaining away the intuitive appeal of the A-theory of time and the endurance theory of persistence. The
A-theory has seemed intuitively appealing because the nature of temporal experience makes it natural for us to use one-place
predicates like past to deal with what are really two-place relations, one of whose constituents is unarticulated. The endurance view can be treated
in a similar way; the temporal boundaries of temporal parts of objects are unarticulated in experience and this makes it seem
that the very same entity exists at different times. 相似文献

This paper responds to Susan Hurley's attempt to undermine the adequacy of the distinction at the heart of the internalism-externalism debate about reasons for action. The paper shows that Hurley's argument fails and then, more positively, indicates a neat way to characterize the distinction. 相似文献

In a non-clinical sample (N = 751), we investigated relations among two subscales (self-reported intrusiveness of unwanted thoughts and thought suppression) of the White Bear Suppression Inventory (WBSI), metacognitive beliefs, and proneness to auditory verbal hallucinations (AVHs). Both subscales of the WBSI were found to be related to AVH-proneness and strongly positively related to metacognitive beliefs about the uncontrollability and danger of thoughts. Regression analyses were used to test models of the relations among AVH-proneness and a range of metacognitive beliefs. When the WBSI subscale relating to the self-reported intrusiveness of unwanted thoughts was controlled for, the metacognitive style that was the strongest predictor of AVH-proneness was cognitive self-consciousness. Cognitive confidence and beliefs about the uncontrollability of thoughts were also significant predictors of AVH-proneness. These findings are used to revise existing models of the relations between metacognitive beliefs and AVHs. Implications for the management of AVHs are discussed. 相似文献
