Is there reason to be concerned about what has been seen as an increasing trend for discourse on complex issues to be confined to an “echo chamber” of like-minded individuals? To investigate how thinking regarding an issue changes in form following concentrated discourse with like-minded peers, we undertook a qualitative examination of changes in the reasoning that 34 older adults used to justify their positions prior to and following such discourse. They showed a divergence of patterns. A minority abandoned mention of previously expressed ideas at odds with their own positions or otherwise narrowed the reasoning used to justify their positions. Consistent with findings from previous studies, only a minority showed increased certainty and/or extremity (polarisation) on quantitative scales. Countering this minority were a larger proportion whose thinking appeared to benefit from such engagement in several respects that we describe. A follow-up study compares results for a sample of young adults. 相似文献

ABSTRACTThis chapter examines the intersection of power, ritual, and the sacred through the lens of performing drag as a tool to subvert dominant notions of theological discourse. Grounded in Cheng’s assertion that queer theology is transgressive (Radical Love) and Althaus-Reid’s Indecent Theology, the foundational text which introduces the concept of theology as destabilizing and grounded in subversion, particularly in the realm of sexuality, we critique the forces of power operating within Catholicism. We ask: Whose bodies are allowed to play a powerful role in Catholicism? How has ritual performance perpetuated the colonization of the mind/spirit and how can it be used to undo that same colonization? In discussing a public drag performance using George Michael’s “Father Figure,” we suggest the possibility of liberation that exists in bringing theology into queer spaces, extending theology beyond the realm of religious institutions or the academy. 相似文献

The current studies utilized drift diffusion modeling (DDM) to examine how reinforcement and stimulant medication affect cognitive task performance in children with ADHD. In Study 1, children with (n = 25; 88 % male) and without ADHD (n = 33; 82 % male) completed a 2-choice discrimination task at baseline (100 trials) and again a week later under alternating reinforcement and no-reinforcement contingencies (400 trials total). In Study 2, participants with ADHD (n = 29; 72 % male) completed a double-blind, placebo-controlled trial of 0.3 and 0.6 mg/kg methylphenidate and completed the same task utilized in Study 1 at baseline (100 trials). Children with ADHD accumulated information at a much slower rate than controls, as evidenced by a lower drift rate. Groups were similar in nondecision time and boundary separation. Both reinforcement and stimulant medication markedly improved drift rate in children with ADHD (ds = 0.70 and 0.95 for reinforcement and methylphenidate, respectively); both treatments also reduced boundary separation (ds = 0.70 and 0.39). Reinforcement, which emphasized speeded accuracy, reduced nondecision time (d = 0.37), whereas stimulant medication increased nondecision time (d = 0.38). These studies provide initial evidence that frontline treatments for ADHD primarily impact cognitive performance in youth with ADHD by improving the speed/efficiency of information accumulation. Treatment effects on other DDM parameters may vary between treatments or interact with task parameters (number of trials, task difficulty). DDM, in conjunction with other approaches, may be helpful in clarifying the specific cognitive processes that are disrupted in ADHD, as well as the basic mechanisms that underlie the efficacy of ADHD treatments. 相似文献

The Visual World Paradigm (VWP) presents listeners with a challenging problem: They must integrate two disparate signals, the spoken language and the visual context, in support of action (e.g., complex movements of the eyes across a scene). We present Impulse Processing, a dynamical systems approach to incremental eye movements in the visual world that suggests a framework for integrating language, vision, and action generally. Our approach assumes that impulses driven by the language and the visual context impinge minutely on a dynamical landscape of attractors corresponding to the potential eye-movement behaviors of the system. We test three unique predictions of our approach in an empirical study in the VWP, and describe an implementation in an artificial neural network. We discuss the Impulse Processing framework in relation to other models of the VWP. 相似文献

The current study provides convergent, discriminant, and incremental validity data for a new measure of schizotypy from the perspective of the five-factor model (FFM) of general personality structure. Nine schizotypy scales were constructed as maladaptive variants of respective facets of the FFM (e.g., Aberrant Ideas as a maladaptive variant of FFM Openness to Ideas). On the basis of data from 143 undergraduates, the convergent validity of these nine scales was tested with respect to seven established measures of schizotypy and the respective facets of the FFM. Discriminant validity was tested with respect to facets from other FFM domains and components of schizotypy. Incremental validity was tested with respect to the ability of the FFM schizotypy scales to account for variance in two established measures of schizotypy, after variance accounted for by respective FFM facets and other established measures of schizotypy were first removed. The findings support the validity of these new scales as measures of schizotypal traits and as maladaptive variants of the FFM. 相似文献

Crowding, the inability to recognize objects in clutter, sets a fundamental limit on conscious visual perception and object recognition throughout most of the visual field. Despite how widespread and essential it is to object recognition, reading and visually guided action, a solid operational definition of what crowding is has only recently become clear. The goal of this review is to provide a broad-based synthesis of the most recent findings in this area, to define what crowding is and is not, and to set the stage for future work that will extend our understanding of crowding well beyond low-level vision. Here we define six diagnostic criteria for what counts as crowding, and further describe factors that both escape and break crowding. All of these lead to the conclusion that crowding occurs at multiple stages in the visual hierarchy. 相似文献

Short acquisition-extinction intervals (immediate extinction) can lead to either more or less spontaneous recovery than long acquisition-extinction intervals (delayed extinction). Using rat subjects, we observed less spontaneous recovery following immediate than delayed extinction (Experiment 1). However, this was the case only if a relatively long extinction-test interval was used; a relatively short extinction-test interval yielded the opposite result (Experiment 2). Previous data appear consistent with this observation suggesting that, although delayed extinction appears more beneficial in the short term, immediate extinction may have more favorable long-term effects. These observations may have important implications for attenuation of relapse in clinical situations. 相似文献

There has been increasing interest in the question of how the brain encodes the order of letters in a written word. This problem is of practical and theoretical interest, so it is important to distinguish between competing computational models. This article compares the SERIOL and SOLAR theories on their biological plausibility and ability to explain experimental results at the orthographic and lexical levels. 相似文献

To reduce employee counterproductive work behaviors (CWBs), organizations may choose to utilize a financial history (FH) instrument during the selection process. To date, no published empirical research has attempted to determine the validity of such a practice. Consequently, the purpose of this study was to determine if employees with FH concerns, which were identified during the selection process and their 5‐year subsequent reinvestigation, were more likely to engage in CWBs, which were objectively measured through an examination of misconduct cases. Results from a random sample of 2519 employees indicated that those with FH concerns were significantly more likely to engage in CWBs than those without FH concerns. Implications to research and practice are discussed. 相似文献
