Developmental Origins of Biological Explanations: The case of infants’ internal property bias

People’s explanations about the biological world are heavily biased toward internal, non-obvious properties. Adults and children as young as 5 years of age find internal properties more causally central than external features for explaining general biological processes and category membership. In this paper, we describe how this ‘internal property bias’ may be grounded in two different developmental precursors observed in studies with infants: (1) an early understanding of biological agency that is apparent in infants’ reasoning about animals, and (2) the acquisition of kind-based representations that distinguish between essential and accidental properties, spanning from animals to artifacts. We argue that these precursors may support the progressive construction of the notion of biological kinds and explanations during childhood. Shortly after their first year of life, infants seem to represent the internal properties of animates as more central and identity-determining that external properties. Over time, this skeletal notion of biological kinds is integrated into diverse explanations about kind membership and biological processes, with an increasingly better understanding of the causal role of internal properties.     

Self-Disclosure and Spiritual Well-Being in Pastors Seeking Professional Psychological Help

Pastoral mental health is a topic that has only rarely been researched empirically in the psychological literature, yet a pastor’s mental health can have a significant impact on churches, communities, and even nations (Royal and Thompson, Journal of Psychology and Christianity, 31(3), 195–204, 2012). One of the thoughts prompting this research is that evangelical pastors might be expected to resist the findings of psychological research and lack understanding of specific mental illnesses they are potentially facing. Combined with historical and cultural dynamics that could influence resistance to professional psychological help, evangelical pastors have personal, internal factors that could also strengthen resistance, including the researched issues of self-disclosure flexibility and spiritual well-being. A correlational research design with multivariate regression was used to determine potentially significant or predictive relationships between the relevant factors. Among evangelical seminary students (N = 251) preparing for parish-based pastoral ministry, this research determined that no significant relationship, predictive or otherwise, existed between self-disclosure flexibility, spiritual well-being, and attitudes toward seeking professional psychological help. Implications include a shift in focus toward external factors influencing pastors’ help-seeking attitudes, such as the need for the mental health community to develop connections with evangelical pastors and the development of more support for Christian mental health professionals in the larger evangelical community.     

Testing probability matching and episodic retrieval accounts of response repetition effects in task switching

This study takes inventory of available evidence on response repetition (RR) effects in task switching, in particular the evidence for RR cost when the task switches. The review reveals that relatively few task-switching studies in which RR effects were addressed have shown statistical support for RR cost, and that almost all are affected by 1 of 2 potential artifacts, either a response bias caused by disallowing stimulus repetitions or the effect of including stimulus repetitions in data analysis. New results with these factors controlled support an episodic retrieval model in which features of the retrieved trace, including the stimulus but also the task, task cue, and response, facilitate or interfere with performance depending on whether they match or mismatch the current processing context.     

The Ways of Criticism

This paper attempts to systematically characterize critical reactions in argumentative discourse, such as objections, critical questions, rebuttals, refutations, counterarguments, and fallacy charges, in order to contribute to the dialogical approach to argumentation. We shall make use of four parameters to characterize distinct types of critical reaction. First, a critical reaction has a focus, for example on the standpoint, or on another part of an argument. Second, critical reactions appeal to some kind of norm, argumentative or other. Third, they each have a particular illocutionary force, which may include that of giving strategic advice to the other. Fourth, a critical reaction occurs at a particular level of dialogue (the ground level or some meta-level). The concepts here developed shall be applied to discussions of critical reactions by Aristotle and by some contemporary authors.     

Nonclinical use of online social networking sites: new and old challenges to medical professionalism

The AMA Council on Ethical and Judicial Affairs (CEJA) has written a position paper on how social medical use challenges medical professionalism. The report offers persuasive ethical and practical guidelines for nonclinical internet use, specifically for social networking. This commentary provides a framework from which to apply these guidelines, but adds that there may be important situations in which physicians are not able to act in accordance. The guidelines call for professional reporting of questionable online portrayals or behaviors, but this commentary argues that this may be not only cumbersome to implement, but may violate aspects of constitutional rights. While online social networking may in many ways be a new application of old challenges, there may be other aspects that require novel approaches to medical professionalism.     

Toddlers with Autism Spectrum Disorder are more successful at visual search than typically developing toddlers

Plaisted, O'Riordan and colleagues (Plaisted, O'Riordan & Baron-Cohen, 1998; O'Riordan, 2004) showed that school-age children and adults with Autism Spectrum Disorder (ASD) are faster at finding targets in certain types of visual search tasks than typical controls. Currently though, there is very little known about the visual search skills of very young children (1-3-year-olds) - either typically developing or with ASD. We used an eye-tracker to measure looking behavior, providing fine-grained measures of visual search in 2.5-year-old toddlers with and without ASD (this representing the age by which many children may first receive a diagnosis of ASD). Importantly, our paradigm required no verbal instructions or feedback, making the task appropriate for toddlers who are pre- or nonverbal. We found that toddlers with ASD were more successful at finding the target than typically developing, age-matched controls. Further, our paradigm allowed us to estimate the number of items scrutinized per trial, revealing that for large set size conjunctive search, toddlers with ASD scrutinized as many as twice the number of items as typically developing toddlers, in the same amount of time.
