In this interrupted case, students read about the alarm-calling behavior of a certain type of ground squirrel and then work in groups to develop hypotheses to explain the behavior and describe data that might be used to test their hypotheses. Students are then given real data and asked to interpret the evolutionary relevance of the results.…

The Edward Jones Company recently initiated financial sponsorship of team-based competitions in six undergraduate business core classes at Baylor University.

A vast literature has examined the impact of family income on the health and development outcomes of children. One channel through which increased income may operate is an improvement in a family's ability to provide food, shelter, clothing, books, and other expenditure-related inputs to a child's development. In addition to this channel, many…

Social order is possible only if individuals forgo the narrow pursuit of self-interest for the greater good. For over a century, social scientists have argued that sympathy mitigates self-interest and recent empirical work supports this claim. Much less is known about why actors experience sympathy in the first place, particularly in fleeting…

Although there is growing consensus that parental stress is a risk factor in child development, longitudinal studies of its effects are few. This study tested a sample of 231 mother-child dyads in terms of whether the relations between the global experience of stress in mothers (perceived stress scale) and child temperamental characteristics…

Disagreements exist among textbook authors, curriculum developers, and even among science and mathematics educators/researchers regarding the meanings and roles of several key nature-of-science (NOS) and nature-of-mathematics (NOM) terms such as proof, disproof, hypotheses, predictions, theories, laws, conjectures, axioms, theorems, and…

This study examined a model of international students' educational satisfaction in the U.S. Using Communication Theory of Identity as a framework, the authors proposed that personal-enacted identity gaps and personal-relational identity gaps contribute to international students' educational satisfaction. Furthermore, acculturation and perceived…

Research indicates that the relationship between socioeconomic status (SES) and delinquency is not as strong as suggested by the leading crime theories. This article argues that such theories do not predict that SES in and of itself causes delinquency but rather that the economic problems associated with SES cause delinquency. Such problems…

This study examined the role of Hispanic students' friendships with White non-Hispanics (n-Hs) and African Americans (AAs) in predicting implicit and explicit prejudices toward these groups. Participants (N = 73) completed implicit and explicit attitude measures and a friendship questionnaire. Friendships were associated with implicit attitudes…

The aim of this study was to investigate the nature of tutor and student online communication and collaboration activities in a blended learning course. The hypothesis that these activities are related to student learning performance (exam results) was tested based on the number of messages posted, as well as the nature of these messages (type of…

This study investigated young children's reports of when learning occurred. A total of 96 4-, 5-, and 6-year-olds were recruited from suburban preschools and elementary schools. The children learned an animal fact and a body movement. A week later, children learned another animal fact and another body movement and then answered questions about…

Using data from a random sample of 580 midwestern women, the authors explore the association between lifetime infertility and life satisfaction. Past research shows lower life satisfaction among those seeking help for infertility. The authors find no direct effects of lifetime infertility, regardless of perception of a problem, on life…

When faced with shame, children can either respond in submissive ways to withdraw from their environment or in externalizing ways to oppose their environment. This study tested the hypothesis that fragile-positive views of self predispose children to respond in externalizing ways to shame situations. Narcissism, actual and perceived social…

Historically, accounts of object representation and perceived similarity have focused on intrinsic features. Although more recent accounts have explored how objects, scenes, and situations containing common relational structures come to be perceived as similar, less is known about how the perceived similarity of parts or objects embedded within…

This study examines the mechanisms through which experiences in the home domain influence work performance by bringing together the literature on recovery and the work-family interface. A longitudinal study among 123 employees from different organizations was conducted to investigate whether need for recovery and home-work interference (HWI)…
