In this paper, it is argued that single function dual process theory is a more credible psychological account of non-monotonicity in human conditional reasoning than recent attempts to apply logic programming (LP) approaches in artificial intelligence to these data. LP is introduced and among other critiques, it is argued that it is psychologically unrealistic in a similar way to hash coding in the classicism vs. connectionism debate. Second, it is argued that causal Bayes nets provide a framework for modelling probabilistic conditional inference in System 2 that can deal with patterns of inference LP cannot. Third, we offer some speculations on how the cognitive system may avoid problems for System 1 identified by Fodor in 1983. We conclude that while many problems remain, the probabilistic single function dual processing theory is to be preferred over LP as an account of the non-monotonicity of human reasoning.  相似文献

John Leslie presents a thought experiment to show that chances are sometimes observer-relative in a paradoxical way. The pivotal assumption in his argument – a version of the weak anthropic principle – is the same as the one used to get the disturbing Doomsday argument off the ground. I show that Leslie's thought experiment trades on the sense/reference ambiguity and is fallacious. I then describe a related case where chances are observer-relative in an interesting way. But not in a paradoxical way. The result can be generalized: At least for a very wide range of cases, the weak anthropic principle does not giverise to paradoxical observer-relative chances. This finding could be taken to give new indirect support to the doomsday argument.  相似文献

What's aesthetically interesting or significant about electronic dance music? The first answer I consider here is that dancing is significant. Using literature on groove, dance and expression, I sketch an account of club dancing as expressive activity. I next consider the aesthetic achievements of DJs, introducing two conceptions of what they do. These thoughts lead to discussions of dance music's ontology. I suggest that the fundamental work of dance music is the mix and that mixes require their own ontology, distinct from ontologies of recordings or improvisations. Finally, I explore two aspects of dance music's aesthetics: its connection with repetition and repetitiveness and its use of electronic sounds and technologies. I conclude with some speculative thoughts about the unique relation dance music bears to repetition and electronics. This article is Part II of two; in Part I, I consider the problem of defining dance music, via the framing question of authenticity. I explore history, genre, scenes and subcultures, and blackness.  相似文献

Identifying with a group can contribute to a sense of well‐being. The mechanisms involved are diverse: social identification with a group can impact individuals' beliefs about issues such as their connections with others, the availability of social support, the meaningfulness of existence, and the continuity of their identity. Yet, there seems to be a common theme to these mechanisms: identification with a group encourages the belief that one can cope with the stressors one faces (which is associated with better well‐being). Our research investigated the relationship between identification, beliefs about coping, and well‐being in a survey (N = 792) administered in rural North India. Using structural equation modelling, we found that social identification as a Hindu had positive and indirect associations with three measures of well‐being through the belief that one can cope with everyday stressors. We also found residual associations between participants' social identification as a Hindu and two measures of well‐being in which higher identification was associated with poorer well‐being. We discuss these findings and their implication for understanding the relationship between social identification (especially with large‐scale group memberships) and well‐being. We also discuss the application of social psychological theory developed in the urban West to rural north India. © 2014 The Authors.

We surveyed 280 students (61% girls; M = 15.3 years) and, in the context of goal setting theory and self‐regulation, tested a cross‐sectional model in which goal orientation (learning, performance–prove, performance–avoid) was viewed as an antecedent to self‐efficacy and outcome expectations, self‐efficacy and outcome expectations were tested as antecedents to goal setting, and goal setting tested as an antecedent to career‐striving behaviors (exploration, planning). After controlling for educational achievement, learning orientation was directly, positively, associated with self‐efficacy and outcome expectations, and indirectly associated with career aspirations, career exploration, and planning; and performance–avoid orientation was negatively associated with self‐efficacy. The study demonstrated that goal orientation is an important variable to consider when examining career development in adolescents.  相似文献

Driving toward a goal (DTAG) is a compliance technique derived from observed persuasion practice (e.g., telethons) wherein the persuader utilizes a goal pitch (e.g., “Help us raise $500”) and progress toward a goal (e.g., a tote board) to encourage compliance. It was postulated that DTAG would be more effective than legitimizing a paltry contribution (LPC) at increasing compliance rate, size, and stability. In Study 1, a fundraising field experiment (N = 840 donations) found that LPC garnered significantly more donations and DTAG garnered significantly larger donations. In Study 2, a lab experiment (N = 992 participants) found that LPC garnered more donations at Time 1, DTAG garnered more donations over time (eventually matching LPC), and LPC yielded smaller donations over time.  相似文献
