Recent arguments in the social sciences exhort a turn to affect and, either explicitly or by implication, a move away from or beyond the earlier turn to language. This conveys a presumption that the site and logic of discursive investigation must inevitably be different to the site and logic of affective investigation. Instead, this article suggests that a nonreductive psychosocial understanding of both discourse and affect needs a way of dissolving the dualism which inhabits and motivates much current debate around discursive and affective “fields.” This article illustrates a route towards dismantling the apparent segregation of discourse and affect in the call to an affective turn. The data come from a project exploring women’s talk of success and failure. Analysis here focuses on affective-discursive practices in discussion of “failed attempts to control body weight” set within the context of contemporary western neoliberal ideology. Discourse and affect are both approached as semiotic, relational practice. As such, affect is made accessible to analysis via concepts already familiar in studies of discursive practice in social psychology, including the reproduction and negotiation of ideologies and the management of trouble. This analytic focus on practical deployments in interaction enables epistemological and ontological psychosocial arguments to be grounded in practical discursive-affective accomplishments.  相似文献

Common-sense folk psychology and mainstream philosophy of action agree about decisions: these are under an agent's direct control, and are thus intentional actions for which agents can be held responsible. I begin this paper by presenting a problem for this view. In short, since the content of the motivational attitudes that drive deliberation and decision remains open-ended until the moment of decision, it is unclear how agents can be thought to exercise control over what they decide at the moment of deciding. I note that this problem might motivate a non-actional view of deciding—a view that decisions are not actions, but are instead passive events of intention acquisition. For without an understanding of how an agent might exercise control over what is decided at the moment of deciding, we lack a good reason for maintaining commitment to an actional view of deciding. However, I then offer the required account of how agents exercise control over decisions at the moment of deciding. Crucial to this account is an understanding of the relation of practical deliberation to deciding, an understanding of skilled deliberative activity, and the role of attention in the mental action of deciding.  相似文献

In today's Anthropocene, the reality of our growing global population, with its requirement of and strain upon the natural world, and our grave projected ecological outlook pose new challenges for Christian ethicists. How can both people and the earth flourish? Discussed within the context of theological and secular reflections on natural law, this article proposes one answer to such a question through a recasting of the human right to nature by way of a deep and wide understanding of vocation. Using Luther as a prototype who demonstrates the innate value of all life forms and offers an innovative working concept of vocation, it is here shown how an emphasis on vocation, when extended ecologically, can promote the option of life for all.  相似文献

This study examines the relationships between the index of coordination (IdC) and active drag (D) assuming that at constant average speed, average drag equals average propulsion. The relationship between IdC and propulsive efficiency (ep) was also investigated at maximal speed. Twenty national swimmers completed two incremental speed tests swimming front crawl with arms only in free condition and using a measurement of active drag system. Each test was composed of eight 25-m bouts from 60% to 100% of maximal intensity whereby each lap was swum at constant speed. Different regression models were tested to analyse IdC–D relationship. Correlation between IdC and ep was calculated. IdC was linked to D by linear regression (IdC = 0.246 · D  27.06; R2 = 0.88, P < .05); swimmers switched from catch-up to superposition coordination mode at a speed of ∼1.55 m s−1 where average D is ∼110 N. No correlation between IdC and ep at maximal speed was found. The intra-individual analysis revealed that coordination plays an important role in scaling propulsive forces with higher speed levels such that these are adapted to aquatic resistance. Inter-individual analysis showed that high IdC did not relate to a high ep suggesting an individual optimization of force and power generation is at play to reach high speeds.  相似文献

The aim of this study was to evaluate stride-to-stride variability of the lower extremity during walking in individuals with and without chronic ankle instability (CAI) using a nonlinear analysis. Twenty-five participants with self-reported CAI and 27 healthy control participants volunteered for this study. Participants walked on a motor-driven treadmill for 3 min at their selected speed. Lower extremity kinematics in the sagittal and frontal planes were recorded using a passive retroreflective marker motion capture system. The temporal structure of walking variability was analyzed with sample entropy (SampEn). The CAI group produced lower SampEn values in frontal-plane ankle kinematics compared to the control group (P = .04). No significant group differences were observed for SampEn values of other kinematics (P > .05). Participants with CAI demonstrated less stride-to-stride variability of the frontal plane ankle kinematics compared to healthy controls. Decreased variability of walking patterns demonstrated by participants with CAI indicates that the presence of CAI may be associated with a less adaptable sensorimotor system to environmental changes. The altered sensorimotor function associated with CAI may be targets for clinical interventions, and it is critical to explore how interventions protocols affect sensorimotor system function.  相似文献

An experiment that utilized a 16-element movement sequence was designed to determine the impact of eye movements on sequence learning. The participants were randomly assigned to two experimental groups: a group that was permitted to use eye movements (FREE) and a second group (FIX) that was instructed to fixate on a marker during acquisition (ACQ). A retention test (RET) was designed to provide a measure of learning, and two transfer tests were designed to determine the extent to which eye movements influenced sequence learning. The results demonstrated that both groups decreased the response time to produce the sequence, but the participants in the FREE group performed the sequence more quickly than participants of the FIX group during the ACQ, RET and the two transfer tests. Furthermore, continuous visual control of response execution was reduced over the course of learning. The results of the transfer tests indicated that oculomotor information regarding the sequence can be stored in memory and enhances response production.  相似文献
