The problem of weakness of the will is often thought to arise because ofan assumption that freely, deliberately and intentionally doing something must correspondto the agent's positive evaluation of doing that thing. In contemporary philosophy, a verycommon response to the problem of weakness has been to adopt the view that free, deliberateaction does not need to correspond to any positive evaluation at all. Much of thesupport for this view has come from the difficulties the denial of it has been thought togive rise to, both with respect to giving an account of weakness, as well as explaining thefuture-directed nature of intentions. In this paper I argue that most of these difficulties onlyarise for one particular version of the view that free, deliberate action must correspond toa positive evaluation, a version associated with Donald Davidson's account of weakness.However, another version of this view is possible, and I argue that it escapes the standardobjections to the Davidsonian account. 相似文献
Dementia is among the most terrible diseases humans can have. Of all of the things that careproviders could do to enhance the quality of life that persons with dementia have, which ones should they do? 相似文献
Can we perceive others' mental states? Wittgenstein is often claimed to hold, like some phenomenologists, that we can. The view thus attributed to Wittgenstein is a view about the correct explanation of mindreading: He is taken to be answering a question about the kind of process mindreading involves. But although Wittgenstein claims we see others' emotions, he denies that he is thereby making any claim about that underlying process and, moreover, denies that any underlying process could have the significance it is claimed to have for this debate. For Wittgenstein, the question is not “Is this perception?” but “What do we mean by ‘perception' here?” and that question is answered by investigating the grammar of the relevant concepts. That investigation, however, reveals similarities and differences between what we call “perception” here and elsewhere. Hence, Wittgenstein's answer to the question “Can we perceive others' mental states?” is yes and no: Both responses can be justified by appeal to different concepts of perception. Wittgenstein, then, has much to contribute to our understanding of mindreading, but what he has to contribute is nothing like the view typically attributed to him here. 相似文献
Advance information about the location of a stimulus (attentional cueing) does not affect the Simon effect (a shortening of manual response times whenever the position of a stimulus that is irrelevant for the task corresponds to the side of the response). However, advance information about the side of a response (intentional cueing) enhances the Simon effect. At first sight, these well-established results contradict two important assumptions about the origin of the Simon effect: (a) the effect originates at least in part in a covert shift of visual attention that forces the preparation of a response towards the location of the attentional shift and (b) interference between stimulus location and response side takes place within a response selection stage. We replicated the behavioral finding in a study that measured event-related potentials (ERPs) of the EEG. ERPs indicated that the mechanisms causing the Simon effect remain widely unaffected by advance information. Clear evidence for both response preparation and attentional shifts in the cue-target interval was found. Additionally, ERPs suggested that the increment of the Simon effect by intentional cueing might be due to perceptual factors rather than to an alteration in the mechanisms involved in the generation of a regular Simon effect. The implications of these data for the role of attention and of response selection in Simon tasks are discussed. 相似文献
College students were trained on problems similar to the water jar problems developed by Luchins (1942). Some students were instructed that a particular rule would solve all the problems, others had the same problems but were not instructed about the rule, and a third set of students had a series of novel problems in which no single rule operated throughout. In two experiments students in the instructed rule group not only performed best in training but also performed best when transferred to a condition in which a single novel rule was appropriate. Although results from the set of conditions most similar to those of Luchins suggested that students sometimes inappropriately persisted in rule usage, the overall results suggest that rigidity is not a necessary outcome of instructed problem solving. Indeed, many of the results were consistent with the notion that instructed problem solving is flexible problem solving. 相似文献
Emotional Lability (EL) is a source of impairment in multiple mental disorders of children, including attention-deficit/hyperactivity disorder (ADHD). It has been proposed that the overlap between EL and ADHD symptoms is the result of common neuropsychological deficits. The aim of the present study was to test this hypothesis by using a multi-method approach. In a mixed sample of 61 children (49 community sample and 12 children with an ADHD diagnosis) aged between 8 and 12 years, we examined the relationship between parental reports of ADHD and EL, real-time children’s emotional expressions in an experimental context, children’s performance on neuropsychological tasks and parental ratings of neuropsychological functioning. Parental EL ratings were significantly predicted by task-based reaction time variability and by questionnaire measures of Self-Direction & Organization and Arousal Regulation. Parental EL ratings were also significantly related to both ADHD symptom dimensions. After controlling for shared neuropsychological factors, ADHD symptoms no longer predicted parental EL ratings. Neuropsychological task performance was not significantly related to real time emotional expressions. However, positive emotional expressions were significantly predicted by higher parental ratings of Cognition and negative emotional expressions by parental ratings of low Effort engagement – accounting for some of the correlation with ADHD symptoms. The current results highlight the plausible role of cognitive energetic processes in explaining the EL and ADHD symptom association.
