Evidential diversity and premise probability in young children's inductive judgment

A familiar adage in the philosophy of science is that general hypotheses are better supported by varied evidence than by uniform evidence. Several studies suggest that young children do not respect this principle, and thus suffer from a defect in their inductive methodology. We argue that the diversity principle does not have the normative status that psychologists attribute to it, and should be replaced by a simple rule of probability. We then report experiments designed to detect conformity to the latter rule in children's inductive judgment. The results suggest that young children in both the United States and Taiwan are sensitive to the constraints imposed by the rule on judgments of probability and evidential strength. We conclude with a suggested reinterpretation of the thesis that children's inductive methodology qualifies them as “little scientists.”     

Using Structured Telephone Follow‐up Assessments to Improve Suicide‐Related Adverse Event Detection

Adverse event (AE) detection and reporting practices were compared during the first phase of the Emergency Department Safety Assessment and Follow‐up Evaluation (ED‐SAFE), a suicide intervention study. Data were collected using a combination of chart reviews and structured telephone follow‐up assessments postenrollment. Beyond chart reviews, structured telephone follow‐up assessments identified 45% of the total AEs in our study. Notably, detection of suicide attempts significantly varied by approach with 53 (18%) detected by chart review, 173 (59%) by structured telephone follow‐up assessments, and 69 (23%) marked as duplicates. Findings provide support for utilizing multiple methods for more robust AE detection in suicide research.     

Innovating “Traditional” Women’s Roles: Byzantine Insights for Orthodox Christian Gender Discourse

Some contemporary hierarchically endorsed statements about gender within Orthodox Christianity appeal to “traditional roles” for women. Byzantine hagiographies about women, however, often confound the stability suggested by such rhetoric, and offer a more open “tradition” of Orthodox Christians celebrating diverse and boundary-breaking forms of women’s sanctity (even if via negation of their womanhood). Although these texts betray an unabashedly historical patriarchal perspective, they also can be read as using gender, via an almost apophatic dialectic, to convey theological values that challenge essentialist associations between specific vocations, authoritative positions, and particular sexes. As hagiography is an influential genre for Orthodox beliefs and practices, the ways hagiographers negotiate and depict gender should inform understandings of gender in Orthodox “tradition.”     

Effects of string length on the organization of rat string-pulling behavior

Post-traumatic stress symptoms and post-traumatic growth in children and adolescents 12 months and 24 months after the earthquake and tsunamis in Chile in 2010: A longitudinal study

On 27 February 2010, Chile experienced one of the strongest earthquakes in recorded history. The study aimed to evaluate post-traumatic stress symptoms (PTSS) and post-traumatic growth (PTG) in children and adolescents 12 months (T1) and 24 months (T2) after the earthquake and tsunamis in Chile in 2010. Three hundred twenty-five children and adolescents (47.4% girls; 52.6% boys) between the ages of 10 and 16 years participated in the study. The instruments included the Revised Post-traumatic Growth Inventory for Children by Kilmer et al., the Childhood PTSD Scale by Foa et al. and the Rumination Scale for Children by Cryder et al., as well as a scale to assess the severity of the event and a sociodemographic questionnaire. The PTSS and PTG scores decreased at T2. In addition, the main predictors of PTSS and PTG were disruptive experiences, losses after the event and intrusive and deliberate rumination during the previous year. These results enhance understanding of factors related to PTG, improve the ability to predict PTSS and PTG in children and adolescents following natural disasters, and inform the design of intervention strategies to promote better mental health in those affected.     

Random word generation reveals spatial encoding of syllabic word length

Existing random number generation studies demonstrate the presence of an embodied attentional bias in spontaneous number production corresponding to the horizontal Mental Number Line: Larger numbers are produced on right-hand turns and smaller numbers on left-hand turns (Loetscher et al.,2008, Curr. Biol., 18, R60). Furthermore, other concepts were also shown to rely on horizontal attentional displacement (Di Bono and Zorzi, 2013, Quart. J. Exp. Psychol., 66, 2348). In two experiments, we used a novel random word generation paradigm combined with two different ways to orient attention in horizontal space: Participants randomly generated words on left and right head turns (Experiment 1) or following left and right key presses (Experiment 2). In both studies, syllabically longer words were generated on right-hand head turns and following right key strokes. Importantly, variables related to semantic magnitude or cardinality (whether the generated words were plural-marked, referred to uncountable concepts, or were associated with largeness) were not affected by lateral manipulations. We discuss our data in terms of the ATOM (Walsh, 2015, The Oxford handbook of numerical cognition, 552) which suggests a general magnitude mechanism shared by different conceptual domains.
