Luther,learning, and the liberal arts

The learning goals of a well‐designed course in the liberal arts include not only the imparting of knowledge but also the development of critical thinking and disciplinary expertise. A class on Luther can help students acquire those intellectual skills associated with the discipline of history and the liberal arts more generally as they consider broader questions about institutional religion, spirituality, moral choices, and human agency. Current scholarship on how people learn highlights the importance of adequate mental frameworks for the acquisition, retention, and retrieval of new ideas and information. This scholarship underlies the choice of specific strategies used to teach about Luther and the Reformation. Assignments provide “scaffolding,” which begins with modeling and then moves from simpler to more complex assignments. Students practice the specific intellectual skills of critical reading and textual analysis over the course of the semester.     

What triggers prosocial effort? A positive feedback loop between positive activities,kindness, and well-being

Across two studies, we found evidence supporting a positive feedback loop between positive activities, kindness and well-being. In Study 1, participants were randomly assigned to one of four distinct positive activities (versus a neutral writing activity) before spending three weeks engaging in kind acts. We found that the positive activities served as triggers – that is, they predicted greater prosocial effort, which in turn predicted greater well-being immediately following the intervention and at a two-week follow-up. In Study 2, we explored the specific effects of a gratitude trigger, and extended the intervention period to six weeks. Although, we did not replicate the direct effect of the gratitude trigger on prosocial effort, people who wrote gratitude letters (versus writing about their week) reported relatively greater elevation, which predicted greater prosocial effort during the six weeks. In turn, replicating Study 1, greater effort predicted higher well-being immediately following the study.     

Caring for the Caregiver: Identifying the Needs of Those Called to Care Through Partnerships with Congregations

As the older adult population continues to grow, the prevalence of chronic diseases is also increasing, leading to the need for novel ways of managing this large population of patients. One solution is to focus on informal caregivers. These informal caregivers already make a substantial contribution to our nation’s healthcare finances and patient health outcomes. Caregivers also derive benefits from caring for their family member or friend; however, it is not uncommon for these individuals to experience negative health consequences, or what is often called “burden of care.” Those called to care are not without their own burdens, and they must frequently make significant lifestyle adjustments that impact their own health. Therefore, for caregivers to be effective, caring for the caregivers must be a focus of medicine in the twenty-first century.     

High maternal aggression in dwarf hamsters (Phodopus campbelli and P. sungorus)

The defense of offspring, termed maternal aggression, is a highly conserved behavior in mammals, including rodents. This study examined relative levels of maternal aggression in two closely related dwarf hamster species, Phodopus campbelli and P. sungorus, that normally inhabit high latitude, boreal environments. When tested with first litters and with the breeder male remaining with the female (for P. campbelli the male is necessary for successful rearing of offspring), both species exhibited high levels of maternal aggression with average duration of aggressive behavior>80 sec for a 10 min test. For P. sungorus, males are not required to rear offspring. P. sungorus females with either one or multiple litters (singly housed after impregnation) exhibited significantly higher levels of aggression (>300 sec) relative to females co‐housed with the sires. In terms of species differences in attack style, P. campbelli exhibited a boxing or clawing strategy for ～50% of total attack time, but for P. sungorus, this form of attack occurred<5% of the time. For P. sungorus, attacks to the vulnerable belly and flank constituted>90% of all attacks, but these regions were attacked ～50% of the time for P. campbelli. A survey of levels of maternal aggression of rodents in other genera suggests that maternal aggression in Phodopus is at the high end of the spectrum. Results of this study suggest that the presence of the breeder male may actually suppress aggression in P. sungorus. This fact, as well as its high level of aggression and its distant relationship to mice and rats, suggest P. sungorus as a possible model for future studies on the neurobiological basis of maternal aggression. The relationship between the high rates of maternal aggression and life history strategy in Phodopus is discussed. Aggr. Behav. 00:000–000, 2005. © 2005 Wiley‐Liss, Inc.     

Building Collaborative Mental Health Teams in Schools Through MFT School Certification: Initial Findings

Building collaborative multidisciplinary mental health teams to boost student achievement has been a growing initiative in American schools since the 1970s. Marriage and Family Therapists (MFTs)joined those teams in 2008, when Connecticut became the first state to certify MFTs for schoolbased practice. This article chronicles the history of that collaboration and reports initial research into MFT school-based participation on those teams.     

How to measure working memory capacity in the change detection paradigm

Although the measurement of working memory capacity is crucial to understanding working memory and its interaction with other cognitive faculties, there are inconsistencies in the literature on how to measure capacity. We address the measurement in the change detection paradigm, popularized by Luck and Vogel (Nature, 390, 279-281, 1997). Two measures for this task-from Pashler (Perception & Psychophysics, 44, 369-378, 1988) and Cowan (The Behavioral and Brain Sciences, 24, 87-114, 2001), respectively-have been used interchangeably, even though they may yield qualitatively different conclusions. We show that the choice between these two measures is not arbitrary. Although they are motivated by the same underlying discrete-slots working memory model, each is applicable only to a specific task; the two are never interchangeable. In the course of deriving these measures, we discuss subtle but consequential flaws in the underlying discrete-slots model. These flaws motivate revision in the modal model and capacity measures.
