Implicit theories moderate the relation of positive future fantasies to academic outcomes

We hypothesized and observed that the degree to which students endorsed entity theories - the view that intelligence is fixed rather than malleable - attenuated the affective benefits and exacerbated the achievement drawbacks of positive fantasies in the academic domain. Positive fantasies only predicted low anger and anxiety for schoolchildren who did not strongly endorse entity theories (Study 1), and positive fantasies only predicted poor final school grades for vocational students who did strongly endorse entity theories (Study 2). An experiment indicated that for university students with stronger entity theories, positive fantasies demanded relatively little attention (Study 3), suggesting that positive fantasies obscure the opportunity for the preemptive self-regulation which promotes successful performance.     

Public Trust in Genomic Risk Assessment for Type 2 Diabetes Mellitus

Patient trust in personal medical information is critical to increasing adherence to physician recommendations and medications. One of the anticipated benefits of learning of one’s genomic risk for common diseases is the increased adoption of screening, preventive care and lifestyle changes. However, the equivocal results thus far reported of the positive impact of knowledge of genomic risk on behavior change may be due to lack of patients’ trust in the results. As part of a clinical study to compare two methods of communication of genomic risk results for Type 2 diabetes mellitus (T2DM), we assessed patients’ trust and preferred methods of delivery of genomic risk information. A total of 300 participants recruited from the general public in Durham, NC were randomized to receive their genomic risk for T2DM in-person from a genetic counselor or online through the testing company’s web-site. Participants completed a baseline survey and three follow-up surveys after receiving results. Overall, participants reported high levels of trust in the test results. Participants who received their results in-person from the genetic counselor were significantly more likely to trust their results than those who reviewed their results on-line (p?=?0.005). There was not a statistically significant difference in levels of trust among participants with increased genetic risk, as compared to other those with decreased or same as population risk (p?=?0.1154). In the event they undergo genomic risk testing again, 55 % of participants overall indicated they would prefer to receive their results online compared to 28 % that would prefer to receive future results in-person. Of those participants preferring to receive results online, 77 % indicated they would prefer to have the option to speak to someone if they had questions with the online results (compared to accessing results online without the option of professional consultation). This is the first study to assess satisfaction with genomic risk testing by the method of delivery of the test result. The higher rate of trust in results delivered in-person suggests that online access reports may not result in serious consideration of results and lack of adoption of recommended preventive recommendations.     

Promoting spiritual well-being: a quasi-experimental test of an element of Hay and Nye’s theory of children’s spirituality

This study is one of the first tests of key implicit claims of Hay and Nye’s theory of children’s spirituality and spiritual development. Two quasi-experimental studies tested two claims: that exposure to six conditions posited as fostering relational consciousness in a programme of spiritual formation promotes spiritual well-being; that the effect of the conditions continues after exposure ends. The results for Study One revealed that length of exposure to any of the six conditions was not a significant predictor of spiritual well-being, F(3, 179)?=?1.49, p = 0.22. Study Two results indicated that as the length of time since exposure increased so did spiritual well-being, r(38)?=?0.39, p = 0.01 at the bivariate level, and F(4, 35)?=?2.4, p = 0.06 in the regression. These results reveal a possible relationship between exposure to the six conditions and spiritual well-being.     

Ethics,Changing Populations,and the Dental Profession

This review emphasizes the worldwide and U.S. evolving population demographics and the need for the dental profession to exercise its professional and ethical duty to expand its traditional patient base to provide needed services.     

Language and life history: a new perspective on the development and evolution of human language

It has long been claimed that Homo sapiens is the only species that has language, but only recently has it been recognized that humans also have an unusual pattern of growth and development. Social mammals have two stages of pre-adult development: infancy and juvenility. Humans have two additional prolonged and pronounced life history stages: childhood, an interval of four years extending between infancy and the juvenile period that follows, and adolescence, a stage of about eight years that stretches from juvenility to adulthood. We begin by reviewing the primary biological and linguistic changes occurring in each of the four pre-adult ontogenetic stages in human life history. Then we attempt to trace the evolution of childhood and juvenility in our hominin ancestors. We propose that several different forms of selection applied in infancy and childhood; and that, in adolescence, elaborated vocal behaviors played a role in courtship and intrasexual competition, enhancing fitness and ultimately integrating performative and pragmatic skills with linguistic knowledge in a broad faculty of language. A theoretical consequence of our proposal is that fossil evidence of the uniquely human stages may be used, with other findings, to date the emergence of language. If important aspects of language cannot appear until sexual maturity, as we propose, then a second consequence is that the development of language requires the whole of modern human ontogeny. Our life history model thus offers new ways of investigating, and thinking about, the evolution, development, and ultimately the nature of human language.     

Personality characteristics associated with susceptibility to false memories

This study examined whether certain personality characteristics are associated with susceptibility to false memories. Participants first answered questions from the Myers-Briggs Type Indicator in order to measure various personality characteristics. They then watched a video excerpt, the simulated eyewitness event. They were next encouraged to lie about the videotaped event during an interview. A week later, some participants recognized confabulated events as being from the video. Two personality characteristics in particular--the introversion-extroversion and thinking-feeling dimensions--were associated with susceptibility to false memories.
