David Hume's Reductionist Epistemology of Testimony

David Hume advances a reductionist epistemology of testimony: testimonial beliefs are justified on the basis of beliefs formed from other sources. This reduction, however, has been misunderstood. Testimonial beliefs are not justified in a manner identical to ordinary empirical beliefs; it is true, they are justified by observation of the conjunction between testimony and its truth, but the nature of the conjunctions has been misunderstood. The observation of these conjunctions provides us with our knowledge of human nature and it is this knowledge which justifies our testimonial beliefs. Hume gives a naturalistic rather than a sceptical account of testimony.     

Production and identification repetition priming in amnestic mild cognitive impairment

The experiment reported here examined implicit memory function, as measured through repetition priming, in amnestic mild cognitive impairment (MCI) to examine whether impairments exist in this aspect of memory function. Young adults, healthy older controls, Alzheimer's disease patients, and MCI participants were asked to perform two types of implicit memory tests (word stem completion and threshold identification repetition priming tasks), as well as a recognition test for studied items. As expected, young adults performed better than the other participants on the recognition test and the word stem completion task; there was equivalent priming across groups on the word identification task. While both the older control and MCI participants showed lower levels of priming on the word stem completion task relative to the young adults, the magnitude of priming was equivalent for these two groups, and reliably greater than that of the dementia participants. These results suggest that not all aspects of memory function are impaired in MCI relative to healthy aging.     

Identity Change Among Ethno-Religious Border Crossers: The Case of the Former Amish

The present study explores identity among the former Amish. While sociologists of religion have long been interested in religious identity, there has been less attention to religious identities among those who cross religious borders. Much of the literature suggests that individuals abandon former religious identities, including ethno-religious ones, when they join a new religious denomination (e.g., Sandomirsky and Wilson in Soc Forces 68:1211–1229, 1990; Sherkat and Wilson in Soc Forces 73:993–1026, 1995). While scholarship on the Jewish case challenges this assumption (e.g., Phillips and Kelner in Soc Relig 67:507–524, 2006; Sharot in Contemp Jew 18:25–43, 1997), research on other religious groups has largely overlooked these insights. This study extend insights from the Jewish case by examining holdover identities among the former Amish and comparing them with the former Ultra-Orthodox Jewish case, making use of Davidman’s (Becoming un-orthodox: stories of ex-Hasidic Jews, Oxford University Press, New York, 2014) research. Analysis of in-depth interviews with 59 former Amish adults reveals that, while those who have left the Amish no longer define themselves as religiously Amish, they do not abandon their Amish identities entirely. Instead, they reconstruct the meanings of their Amishness in varied ways in their non-Amish contexts. Comparison of these patterns with former Ultra-Orthodox Jews illuminates contextual factors, including the Amish practice of adult baptism and differing normative conceptions of Amish and Jewish identities, that contribute to variation in holdover identities across these cases. Altogether, these results suggest that ethno-religious identities are not mutually exclusive of other denominational identities and support the conceptualization of religious identities as complex, multilayered, and constructed in particular contexts in interaction with existing notions about religious groups.     

Meaning construction and integration in children with hydrocephalus

Text comprehension processes were investigated in children with hydrocephalus, a neurodevelopmental disorder associated with good word decoding, but deficient reading comprehension. In Experiment 1, hydrocephalus and control groups were similar in processes related to activating word meanings and using context to enhance meaning. The hydrocephalus group was poorer at suppressing contextually irrelevant meanings. In Experiment 2, the hydrocephalus group had difficulty integrating information from an earlier read sentence to understand a new sentence as textual distance between the two propositions increased, suggesting difficulty in reactivation processes related to comprehension. Results are discussed in relation to cognitive and neurocognitive models of comprehension.     

Giving the Benefit of the Doubt

Abstract

Faced with evidence that what a person said is false, we can nevertheless trust them and so believe what they say – choosing to give them the benefit of the doubt. This is particularly notable when the person is a friend, or someone we are close to. Towards such persons, we demonstrate a remarkable epistemic partiality. We can trust, and so believe, our friends even when the balance of the evidence suggests that what they tell us is false. And insofar as belief is possible, it is also possible to acquire testimonial knowledge on those occasions when the friends know what they tell us. This paper seeks to explain these psychological and epistemological possibilities.     

A Therapeutic Recreation Camp for Children with Congenital Heart Disease: Examining Impact on the Psychosocial Well-Being of Parents

Therapeutic recreation camps have been considered to be an effective context for improving the psychosocial functioning of children with congenital heart disease (CHD). However, there is limited research regarding their impact on parents. Nine parents participated in two semi-structured interviews before and after their children attended a camp for children with CHD. Parents described their perceptions of their children’s camp experiences and identified the psychosocial utility of camp for themselves. Camp enabled parents to let their children grow and be independent, and helped reduce parents’ restricting and overprotective behaviours. Camp also provided parents with respite care, which alleviated their need to be ‘cardiac’ parents. These findings strengthen the case for therapeutic recreation camps and underscore the importance of expanding camp access to more families affected by CHD.     

Children's patterns of reasoning about reading and addition concepts

Children's reasoning was examined within two educational contexts (word reading and addition) so as to understand the factors that contribute to relational reasoning in the two domains. Sixty‐seven 5‐ to 7‐year‐olds were given a series of related words to read or single‐digit addition items to solve (interspersed with unrelated items). The frequency, accuracy, and response times of children's self‐reports on the conceptually related items provided a measure of relational reasoning, while performance on the unrelated addition and reading items provided a measure of procedural skill. The results indicated that the children's ability to use conceptual relations to solve both reading and addition problems enhanced speed and accuracy levels, increased with age, and was related to procedural skill. However, regression analyses revealed that domain‐specific competencies can best explain the use of conceptual relations in both reading and addition. Moreover, a cluster analysis revealed that children differ according to the academic domain in which they first apply conceptual relations and these differences are related to individual variation in their procedural skills within these particular domains. These results highlight the developmental significance of relational reasoning in the context of reading and addition and underscore the importance of concept‐procedure links in explaining children's literacy and arithmetical development.     

A qualitative examination of body image threats using Social Self-Preservation Theory

This study sought to identify and describe comfortable and uncomfortable body-related situations of young women, as well as describe their responses to such situations and strategies they used to cope with body-related threats, using Social Self-Preservation Theory (SSPT) as a guiding framework. Interviews were conducted with college women (N = 23). A theoretical thematic analysis approach was taken to identify, code, and report themes. In general, participants found it difficult to identify specific comfortable situations and responses in those situations. Comfortable situations were characterized by the presence of supportive others and feelings of general calmness and lowered body awareness or self-presentational concerns. Findings regarding uncomfortable body-related situations indicated that the context (e.g., presence of others, body exposure), responses (e.g., embarrassment, inadequacy, awareness of others’ evaluations, faster heart rate), and coping strategies (e.g., avoidance, concealing behaviors) described by participants were consistent with SSPT.     

The Scarlet Letter Study: Five Days of Social Ostracism

Abstract

Over the course of 5 consecutive days, each author agreed to be ostracized for a day at work by the other four coauthors. All coauthors’ offices were in close proximity and were located solely on a single floor and wing of their academic building. Each morning, the name of that day's ostracized individual was drawn, and a scarlet letter “O” was placed above that individual's office door. Ostracizers were instructed to ignore the “Os” by not looking at them, speaking to them, or responding to anything they said. Open-ended individual event-contingent diaries were kept to record participants’ thoughts, feelings, and behaviors each time they were reminded of the ostracism. Despite foreknowledge and consent, attributional confusion surfaced and strong aversive reactions were reported. Findings are framed in terms of Williams's (1997) model of ostracism
