Differential Automatic Processing Deficits in Early Stage Alzheimer's Disease

This experiment sought further support for the view that early stage Alzheimer's disease (AD) disrupts cognitive structures that cast experience into a temporal framework. Forty participants, evenly divided between normal elderly (NE) and persons diagnosed with mild AD, viewed 19 lists of 14 pictures each. Following the presentation of each list participants were asked to identify the most recently experienced picture (target) from 3 pictures. A second stimulus was a picture never previously seen; the third picture was a distracting item that had appeared in the list on either one or three occasions. The results show that whereas choice accuracy of the NE group remained largely unimpaired regardless of the delay between the target and the judgment task or the frequency of the distractor, the AD participants exhibited large and profound deficits in temporal judgments, especially when distractor frequency was greater than the more recent event. In effect, the AD group relied on how often an event occurred rather than the time of its occurrence. This finding is consistent with previous research that found AD patients deficient in forming a temporal representation of their experience.     

The applied value of collaborative memory research in aging: Behavioral and neural considerations

Our aim in this paper is to bring attention to the applied value of collaborative memory research in aging. At this time, much collaborative memory research focuses on the negative effects of collaboration in younger adults, and is primarily basic in nature. Here, we highlight the positive effects of collaboration that have received less attention, with a particular emphasis on the applied value of these effects in older adults. We first review studies to show that recalling in a group improves later individual recall and reduces memory errors in older adults. We then outline a four-step approach towards bridging laboratory and applied collaborative memory research, which involves: (1) complementing traditional paradigms with more ecologically valid paradigms, (2) evaluating these paradigms in applied settings, (3) adapting these paradigms for use with cognitively intact and cognitively impaired populations, and (4) modifying these paradigms to examine the neural systems that operate during collaborative recall.     

Development as a dynamic system

Development is about creating something more from something less, for example, a walking and talking toddler from a helpless infant. One current theoretical framework views the developmental process as a change within a complex dynamic system. Development is seen as the emergent product of many decentralized and local interactions that occur in real time. We examine how studying the multicausality of real-time processes could be the key to understanding change over developmental time. We specifically consider recent research and theory on perseverative reaching by infants as a case study that demonstrates this approach.     

Toward Better Prevention: Constructions of Trust in the Sexual Relationships of Young Women

Research on HIV/AIDS interventions indicates that many heterosexual women implement the construct of trust when deciding if preventive measures are necessary. The personal construct model evaluated in this experiment proposes that young women's choice to resist changing from a trust to a nontrust position can be understood in terms of the relationship between their constructs and the hierarchical organization of their construct subsystems. Findings suggest that women with well-defined networks of implications on their nonpreferred pole of the trust/mistrust construct resist HIV-preventive messages that require them to mistrust their partner because the proposed change will involve successive use of subordinate constructs that are incompatible with each other.     

Does the Public Intellectual Have Intellectual Integrity?

This article is concerned with the devaluation of the work of public intellectuals within the academic community. The principal reason given for this devaluation is that the work of the public intellectual does not have intellectual integrity as independent thought and original scholarship. I develop three models of public intellectual work: the permanent–critic model, the popularizer model, and the public–theorist model. I then consider each model in relation to the concern with intellectual integrity and conclude that both independent thought and original scholarship are possible within work that is engaged with nonacademic publics.     

Ambivalent Sexism and the Dumb Blonde: Men's and Women's Reactions to Sexist Jokes

This article examines the relationship between gender, hostile sexism, benevolent sexism and reactions to a seemingly innocuous genre of sexist humor, the dumb blonde joke. After hearing an audiotaped conversation in which two students swapped dumb blonde jokes, participants high in hostile sexism rated the jokes as more amusing and less offensive than those low in hostile sexism. Among individuals low in hostile sexism, however, benevolent sexism interacted with gender. Specifically, men high in benevolent sexism found the jokes significantly more amusing and less offensive than either women in the same group or men low in both hostile and benevolent sexism. This study replicates and extends previous research examining the relationship between hostile sexism and the enjoyment of sexist humor, and underscores the possibility that benevolent sexism may represent qualitatively distinct attitudes for men and women.     

Psychological Adjustment to Breast Cancer

Breast cancer remains a highly prevalent and extraordinarily stressful experience for hundreds of thousands of women each year in the United States and around the world. Psychological research has provided a picture of the emotional and social impact of breast cancer on patients' lives, and of factors associated with better versus worse adjustment. Psychosocial interventions have been beneficial in decreasing patients' distress and enhancing their quality of life. Recent research also suggests that psychological factors may be related to potentially important biological disease-related processes. In addition to providing an understanding of the psychological factors in breast cancer, research in this area has provided a framework for research on adaptation to health-related stress in general.

The effects of three stimulus‐equivalence testing conditions on emergent US geography relations of children diagnosed with autism

Two children with autism were trained in US geography using a match to sample procedure. Different testing procedures commonly used in stimulus equivalence research were compared, including some conditions with reinforcement for responding to enhance motivation. Both children were able to master the trained geography relations and emergent stimulus relations were also noted. All three testing procedures produced similar effects, suggesting that incorporation of procedures to enhance motivation to respond does not invalidate testing in a stimulus equivalence preparation.

The Search for the Source of Epistemic Good

Knowledge has almost always been treated as good, better than mere true belief, but it is remarkably difficult to explain what it is about knowledge that makes it better. I call this "the value problem." I have previously argued that most forms of reliabilism cannot handle the value problem. In this article I argue that the value problem is more general than a problem for reliabilism, infecting a host of different theories, including some that are internalist. An additional problem is that not all instances of true belief seem to be good on balance, so even if a given instance of knowing p is better than merely truly believing p , not all instances of knowing will be good enough to explain why knowledge has received so much attention in the history of philosophy. The article aims to answer two questions: (1) What makes knowing p better than merely truly believing p ? The answer involves an exploration of the connection between believing and the agency of the knower. Knowing is an act in which the knower gets credit for achieving truth. (2) What makes some instances of knowing good enough to make the investigation of knowledge worthy of so much attention? The answer involves the connection between the good of believing truths of certain kinds and a good life. In the best kinds of knowing, the knower not only gets credit for getting the truth but also gets credit for getting a desirable truth. The kind of value that makes knowledge a fitting object of extensive philosophical inquiry is not independent of moral value and the wider values of a good life.
