It has long been argued that ownership depends upon social groups' establishing and adhering to rights such as the right to use and to exclude others from using one's own property. The authors consider the application of such rights in the interactions of young peers and siblings, and the extent to which parents support their children in establishing and maintaining the entitlement of owners. They show that children, but not their parents, give priority to ownership in settling property disputes, and argue that diverging models of children's relationships account for these differing perspectives of children and parents. 相似文献

Four studies examined dyadic collaboration on quantitative estimation tasks. In accord with the tenets of "na?ve realism," dyad members failed to give due weight to a partner's estimates, especially those greatly divergent from their own. The requirement to reach joint estimates through discussion increased accuracy more than reaching agreement through a mere exchange of numerical "bids." However, even the latter procedure increased accuracy, relative to that of individual estimates (Study 1). Accuracy feedback neither increased weight given to partner's subsequent estimates nor produced improved accuracy (Study 2). Long-term dance partners, who shared a positive estimation bias, failed to improve accuracy when estimating their performance scores (Study 3). Having dyad members ask questions about the bases of partner's estimates produced greater yielding and accuracy increases than having them explain their own estimates (Study 4). The latter two studies provided additional direct and indirect evidence for the role of na?ve realism. 相似文献

Two studies investigated the capacity of a self-affirmation intervention to lower a psychological barrier to conflict resolution. Study 1 used a role-play scenario in which a student negotiated with a professor for greater rewards for work on a collaborative project. A self-affirmation manipulation, in which participants focused on an important personal value, significantly reduced their tendency to derogate a concession offered by the professor relative to one that had not been offered. Study 2 replicated this effect and showed that the phenomenon did not depend on the self-affirmed participant's experience of a heightened sense of deservingness or a tendency to make positive attributions about the professor. Distraction and explicit mood enhancement were also ruled out as mediators of the self-affirmation effect, which appears to stem from motivational rather than explicit cognitive processes. 相似文献

Motor timing is essential for performing self-initiated movement sequences. Here, we investigated how sequence rhythm, or the timing for co-ordinating movements within a sequence, contributes to action preparation, compared with other processes occurring during sequence planning. First, we recorded the readiness potential (RP) in a condition of complex sequence rhythm and in condition of high demand on the timing for sequence initiation. We found that sequence rhythm and sequence initiation are independent processes, with sequence initiation contributing to early RP. Second, we compared the RP recorded in a condition of complex sequence rhythm and in a condition of complex sequence order, in which a complex combination of finger sub-movements had to be correctly ordered within a sequence. We found that sequence rhythm and sequence order share common processes occurring late RP. We suggest that the preparation for movement involves independent processes devoted to different aspects of motor timing and sequencing. 相似文献

Probability matching is a suboptimal behavior that often plagues human decision-making in simple repeated choice tasks. Despite decades of research, recent studies cannot find agreement on what choice strategies lead to probability matching. We propose a solution, showing that two distinct local choice strategies—which make different demands on executive resources—both result in probability-matching behavior on a global level. By placing participants in a simple binary prediction task under dual- versus single-task conditions, we find that individuals with compromised executive resources are driven away from a one-trial-back strategy (utilized by participants with intact executive resources) and towards a strategy that integrates a longer window of past outcomes into the current prediction. Crucially, both groups of participants exhibited probability-matching behavior to the same extent at a global level of analysis. We suggest that these two forms of probability matching are byproducts of the operation of explicit versus implicit systems. 相似文献

Time to task failure of trunk extensor muscles during seated submaximal isometric exertions was assessed in 18 healthy participants using 2 different load types. One required supporting an inertial load (position-matching task) whereas the 2nd required maintaining an equivalent torque against a rigid restraint (force-matching task). Time to task failure was significantly longer for position-matching tasks compared to the force-matching tasks. This finding is opposite to that reported for the appendicular muscles. A subset of 4 individuals completed a 2nd experiment to test the time to task failure of the elbow flexors in the position- and force-matching tasks. Time to task failure of the elbow flexors was significantly longer for the force-matching tasks compared to position matching. Thus, the same population shows that the effects of load type on time to task failure are opposite for the appendicular and axial muscles. This could be an important issue in understanding the mechanisms of task failure, and the endurance capacity of the trunk extensor muscles. 相似文献

To suggest that Daniel Dennett is a deist is to invite ridicule. Dennett is both an avowed atheist and defender of naturalism in philosophy. Yet if we pay heed to the entirety of Dennett’s claims a curious picture emerges. My suggestion is that Hegel and Marx represent the rival responses to what we might call the modern predicament: what is the nature of existence in a world which seems a mechanism? Dennett’s response to this question is Hegelian, and involves a commitment to a religiosity which might surprise those otherwise receptive to his arguments. 相似文献

One of the most dominant approaches to semantics for relevant (and many paraconsistent) logics is the Routley?CMeyer semantics involving a ternary relation on points. To some (many?), this ternary relation has seemed like a technical trick devoid of an intuitively appealing philosophical story that connects it up with conditionality in general. In this paper, we respond to this worry by providing three different philosophical accounts of the ternary relation that correspond to three conceptions of conditionality. We close by briefly discussing a general conception of conditionality that may unify the three given conceptions. 相似文献
