This experiment reports an investigation of the development of selective processing strategies as subjects become increasingly more practised at a serial self-paced RT task. It demonstrates the effect a preceding stimulus can have on the analysis of a current signal and the development of active analytic strategies in favour of passive wholistic processing, with practice. The stimuli used were letters with irrelevant visual noise dot patterns superimposed on them. The letter, or the dot pattern, or both, could be repeated on successive trials. Early in practice repetition of both stimulus components simultaneously produced short reponse latencies relative to repetition of the letter alone. The number of noise dots markedly affected RT. Late in practice, however, letter repetition RTs were small, irrespective of whether or not the noise dot pattern was repeated. Furthermore, the number of noise dots no longer had an effect on the RT to these stimulus transitions. The results suggest that subjects appear to be able to select relevant information to process as they become progressively more practised, even though there is evidence that they compare the current stimulus with an iconic representation of the immediately preceding one. 相似文献

Supported by a network of researchers and practitioners, the goal programming (GP) model is alive today more than ever and is continually fed with theoretical developments and new applications with resounding success. The standard formulation of the GP model was introduced in the earliest of 1960s, and since then, important extensions and numerous applications have been proposed. One of these variants is the stochastic GP model that deals with the uncertainty of some decision‐making situations by using stochastic calculus. In such a situation, the decision maker is not able to assess with certainty the different parameters. However, he or she can provide some information regarding the likelihood of occurrence of the decision‐making parameter values. The aim of this paper is to highlight the main methodological developments of the stochastic GP model and to present an overview of its applications in several domains.

Those who care about and engage in politics frequently fall victim to cognitive bias. Concerns that such bias impacts scholarship recently have prompted debates – notably, in philosophy and psychology – on the proper relationship between research and politics. One proposal emerging from these debates is that researchers studying politics have a professional duty to avoid political activism because it risks biasing their work. While sympathetic to the motivations behind this proposal, I suggest several reasons to reject a blanket duty to avoid activism: (1) even if it reduced bias, this duty would make unreasonable demands on researchers; (2) this duty could hinder research by limiting viewpoint diversity; (3) this duty wrongly implies that academia offers a relative haven from bias compared to politics; and (4) not all forms of political activism pose an equal risk of bias. None of these points suggest that researchers should ignore the risk of bias. Rather, researchers should focus on stronger evidence-based strategies for reducing bias than a blanket recommendation to avoid politics. 相似文献

The purpose of this study was to identify maternal, child, and family factors related to the employment status and employment history of single mothers of low-birth-weight (LBW) and full-term preschoolers. A sample of 121 female-headed, single-parent families with 3-, 4-, and 5-year-old LBW and full-term children was recruited through admission records to three Level III neonatal intensive care units (NICUs) and birth records of two normal newborn nurseries. Results show that the birth of an LBW infant was not related to employment status, number of hours employed per week, or employment history for single mothers. Employed mothers had significantly more education and more positive attitudes toward employment. Controlling for other factors, never being married, and having more children, more federal income, and less positive employment attitudes were predictive of nonemployment. Both employed and nonemployed women expressed preference for employment. 相似文献

In a series of publications I have claimed that by contrast to standard formal languages, quantifiers in natural language combine with a general term to form a quantified argument, in which the general term's role is to determine the domain or plurality over which the quantifier ranges. In a recent paper Zoltán Gendler Szabó tried to provide a counterexample to this analysis and derived from it various conclusions concerning quantification in natural language, claiming it is often ‘bare’. I show that Szabó's example fails, and that even if it were successful his conclusions would not be supported by it. 相似文献

We assessed dysphoric and clinically distressed individuals' ability to ignore the emotional aspects of facial expressions using the Garner speeded‐classification task. Garner's paradigm tests the ability to selectively focus on a single relevant dimension while ignoring variations on other, irrelevant, ones. In the present task, the stimuli were faces of men and women expressing happy, angry, and neutral emotions. In Experiments 1 and 2, dysphoric and nondysphoric participants performed the Garner task, focusing on gender and ignoring emotion (Experiment 1) and focusing on emotion and ignoring gender (Experiment 2). Results suggest that dysphoric individuals exhibited more difficulty ignoring the emotional dimension of social stimuli even under specific instructions to do so than nondysphoric individuals. In Experiments 3 and 4, we replicated these results in clinically distressed and nondistressed individuals. The results of Experiment 3 further suggested that depression was more closely associated with the inability to selectively ignore emotion than was social anxiety. Experiment 4 confirmed that this failure of selective attention was specific to processing emotional, and not gender features. The implications of these findings for cognitive and interpersonal theories of depression are discussed. 相似文献
