The Prediction of Achievement Motivation Using Performance and Attributional Variables

This study was designed to predict achievement motivation with attributions and performance in English course work among 346 ninth-grade boys and girls. Multiple regression analysis indicated that attribution of success to ability was the best predictor of achievement motivation. This finding diverges from previous work that supports the hypothesis that attribution of success to effort is a better predictor. The use of performance as an indicator variable showed that nonfailing students had higher levels of achievement motivation than did failing students.     

They're digging up the road again: The processing cost of Institutional They

It is commonplace to use the pronoun they to refer to agents in certain situations without ever providing a referent, as in On the train, they served really bad coffee. Such an example we call “Institutional They”, because such defaults typically represent the actions of some agent tied stereotypically to a situation. These cases represent an important subset of unheralded pronouns (Gerrig, 1986), pronouns without any explicit antecedent. While in many situations, the occurrence of referential pronouns without explicit antecedents entails a processing cost, an eye-tracking experiment revealed no reliable detectable costs associated with Institutional They. However, there were for singular pronouns without antecedents in the same situations. We argue that Institutional They cases result from properties of plural pronouns (they and them). These will accept underspecified type-referents, while singular pronouns require specified token-referents. Failure to identify token-referents results in disruption of processing in the case of singulars, but not in the case of the plurals.     

Matters Olympic and Paralympic

Over the past several years, I have been arguing that nature sports such as surfing, backcountry skiing, and mountaineering are best described as sports in which athletes interact dynamically with natural features rather than compete with other humans. This article is part of a larger attempt to trace the implications of that view. Specifically, I consider the relationship between nature sports and competition. To this purpose, I address three separate, but related topics: First, I reply to Leslie Howe’s article, ‘On Competing Against Oneself, Or, I Need to Get a Different Voice in My Head’, in which she argues that there is a version of self-competition that is central to nature sports. Second, I argue that adapting nature sports to fit into formal competitive frameworks is problematic because, when we do so, the focus shifts from athletes interacting with natural features to athletes using natural features to outdo other athletes. And third, I argue that nature sports may seem competitive because the interaction between humans and natural features produces a type of intensity that is very similar to the intensity produced in competition. I argue further that because nature sports can produce this intensity in an environment that is not based on competition, they present an important alternative to traditional sports.     

Hemispheric Processing Deficits in Patients with Paranoid Schizophrenia

The purpose of the present study was to investigate hemispheric deficits in individuals with paranoid schizophrenia on four kinds of tasks: dichoptic viewing tasks involving verbal and nonverbal visual stimuli, and dichotic listening tasks involving verbal and nonverbal auditory stimuli. As dependent measures, both accuracy and speed of (correct) responding were measured. The sample recruited for this study consisted of 18 patients with paranoid schizophrenia, 15 outpatients with anxiety disorders, and 20 controls with no history of psychiatric disorders. Results indicated that, relative to the controls, the paranoid schizophrenic patients were less accurate and less efficient on auditory-verbal tasks requiring right hemisphere processing. Unlike the controls, the paranoid schizophrenic patients manifested a lateralized left hemisphere advantage.     

Another view of “we”: Majority and minority group perspectives on a common ingroup identity

Drawing on the evidence of the role of social categorisation and identity in the development and maintenance of intergroup biases, research on the Common Ingroup Identity Model (Gaertner & Dovidio, 2000 Gaertner, S. L. and Dovidio, J. F. 2000. Reducing intergroup bias: The Common Ingroup Identity Model, Philadelphia, PA: The Psychology Press.  [Google Scholar]) has investigated how modifying the ways that the self and others are categorised can reduce prejudice and discrimination. In this article, we review more recent research that extends our initial formulation of the model by considering more fully alternative forms of recategorisation (a dual identity as well as a one-group representation), the different preferences of majority and minority groups for these different forms of recategorised representations, and the potential implications of these different preferences on the content of intergroup interaction and on the possibilities for social change towards equality.     

Strange Affinities in the Search for Personalized Health: New Age Practices and Genetic Testing

A prominent focus of New Age beliefs and practices has always been health and healing—including the use of holistic healing, power crystals, homeopathy, and complementary and alternative medicine. Given its association with modern science and medicine, genetic testing would seem to run counter to New Age alternative medical practices. On the other hand, the use of at-home genetic health tests and the use of such New Age alternative medical practices could both be motivated by a desire for personalized healthcare. Using data generated from a survey fielded on a probability sample of U.S. adults, we examine associations between individuals’ use of at-home genetic health tests and their use of power crystals and acupuncture or other homeopathic medicine. Logistic regression models find that those who use power crystals or homeopathic medicine have significantly greater odds of having used an at-home genetic health test. We discuss the implications of these findings for our understanding of the direct-to-consumer genetic testing market and the relationship between science, religion, and spirituality more broadly.     

视觉表象扫描加工中的认知控制

通过建构一个反向扫描任务而形成任务冲突,在3个实验中考察了视觉表象扫描中认知控制与冲突解决机制。结果发现:(1)视觉表象扫描中出现了任务冲突效应;(2)外源性认知控制增强降低了任务冲突效应,但不影响扫描效率;(3)内源性认知控制增强既降低了任务冲突效应,也提高了反向扫描任务扫描效率。这些结果证实视觉表象扫描中存在一个认知控制机制,并发展了现有冲突解决理论。     

A model of resurgence based on behavioral momentum theory

Resurgence is the reappearance of an extinguished behavior when an alternative behavior reinforced during extinction is subsequently placed on extinction. Resurgence is of particular interest because it may be a source of relapse to problem behavior following treatments involving alternative reinforcement. In this article we develop a quantitative model of resurgence based on the augmented model of extinction provided by behavioral momentum theory. The model suggests that alternative reinforcement during extinction of a target response acts as both an additional source of disruption during extinction and as a source of reinforcement in the context that increases the future strength of the target response. The model does a good job accounting for existing data in the resurgence literature and makes novel and testable predictions. Thus, the model appears to provide a framework for understanding resurgence and serves to integrate the phenomenon into the existing theoretical account of persistence provided by behavioral momentum theory. In addition, we discuss some potential implications of the model for further development of behavioral momentum theory.     

中美医疗损害责任制度改革之比较研究

医疗损害责任已成为现代社会普遍的医疗法律问题。中美两国医疗损害责任制度改革正朝着相反的方向发展。诉讼机制在美国医疗损害责任中的作用由强变弱,医疗诉讼起诉由易变难,医疗损害赔偿由不限制到相对限制,行政管理式的医疗过错责任制度由无到逐渐提议。我国医疗损害责任制度改革恰恰相反,即诉讼制度的作用由弱变强、医疗损害起诉由难到易,医疗损害赔偿由相对限制到不限制、行政管理式的医疗过错责任制度从有到无。我国医疗损害责任制度的改革趋势值得反思。建议借鉴美国医疗损害责任制度改革的经验。
