Getting off the Wheel

Roderick Chisholm argues that in giving an account of knowledge, we must either begin with an account of what knowledge is, and proceed on that basis to identify the particular things that we know, or else start with instances of knowledge, and proceed on that basis to formulate a definition of knowledge. Either approach begs the question against the other. This is the epistemic wheel. This article responds to Chisholm's challenge. It begins with cases of knowledge attribution and builds its account from there, identifying those features that we take to be present in the cases where we have attributed knowledge and those features that seem important when we want to withhold an attribution of knowledge. The proposal does not beg the question against either particularists or methodists; it takes the best features of each view, without beginning with either, and thereby removes us from the wheel.     

Examining the Process of Responding to Circumplex Scales of Interpersonal Values Items: Should Ideal Point Scoring Methods Be Considered?

The Circumplex Scales of Interpersonal Values (CSIV) is a 64-item self-report measure of goals from each octant of the interpersonal circumplex. We used item response theory methods to compare whether dominance models or ideal point models best described how people respond to CSIV items. Specifically, we fit a polytomous dominance model called the generalized partial credit model and an ideal point model of similar complexity called the generalized graded unfolding model to the responses of 1,893 college students. The results of both graphical comparisons of item characteristic curves and statistical comparisons of model fit suggested that an ideal point model best describes the process of responding to CSIV items. The different models produced different rank orderings of high-scoring respondents, but overall the models did not differ in their prediction of criterion variables (agentic and communal interpersonal traits and implicit motives).     

Gender bias triggers diverging science interests between women and men: The role of activity interest appraisals

Women leave science fields at greater rates than men, and loss of interest is a key motivator for leaving. Although research widely demonstrates effects of gender bias on other motivational processes, whether gender bias directly affects feelings of interest toward science activities is unknown. We used a false feedback paradigm to manipulate whether women (Study 1) and men (Study 2) participants perceived the reason for feedback as due to pro-male bias. Because activity interest also depends on how students approach and perform the activity, effects of biased feedback on interest appraisals were isolated by introducing gender bias only after the science activity was completed. When the feedback was perceived as due to pro-male bias, women (Study 1) reported lower interest and men (Study 2) reported greater interest in the science activity, and interest, in turn, positively predicted subsequent requests for career information in both studies. Implications for understanding diverging science interests between women and men are discussed.     

Monkeys display classic signatures of human symbolic arithmetic

Non-human primates compare quantities in a crude manner, by approximating their values. Less is known about the mental transformations that non-humans can perform over approximate quantities, such as arithmetic transformations. There is evidence that human symbolic arithmetic has a deep psychological connection with the primitive, approximate forms of quantification of non-human animals. Here, we ask whether the subtle performance signatures that humans exhibit during symbolic arithmetic also bear a connection to primitive arithmetic. Specifically, we examined the problem size effect, the tie effect, and the practice effect—effects which are commonly observed in children’s math performance in school. We show that, like humans, monkeys exhibited the problem size and tie effects, indicating commonalities in arithmetic algorithms with humans. Unlike humans, however, monkeys did not exhibit a practice effect. Together, these findings provide new evidence for a cognitive relation between non-symbolic and symbolic arithmetic.     

Entrepreneurship in young adults: Initial findings from the young entrepreneurs study

The scientific study of youth entrepreneurship is truly in its infancy, with research on the development of entrepreneurship constrained by theoretical foundations that rely on static, trait-like approaches that equate entrepreneurship with stable personality characteristics. In this article, we define entrepreneurship as a fluid process that relies on the bidirectional interplay between a developing individual and his or her context. We report initial findings from the Young Entrepreneurs Study that clarify how entrepreneurial intentions and actions manifest in youth. We present quantitative analyses that examined the relations between entrepreneurial strengths and entrepreneurial activities in a sample of 3461 college students, and we describe the results of semi-structured interviews from a 48-person subset of our larger sample that explored how entrepreneurial intentions and actions manifested in our sample. We describe a mixed-method triangulation that integrates these two sets of findings, then discuss implications for future research.     

Adolescent Dating Violence: Application of a U.S. Primary Prevention Program in St. Lucia

The purpose of this study was to examine the Choose Respect dating violence prevention program (Centers for Disease Control and Prevention, 2006b , n.d.‐a) with secondary students in St. Lucia. Multivariate analysis of variance results indicated that the Choose Respect program had a positive influence on participants’ attitudes about control in relationships. Significant gender and school effects were found. Implications of these findings for primary prevention efforts targeting dating violence in St. Lucia and limitations of the study are discussed.
