Comparison of blocking strategies informed by precursor assessment to decrease pica

Pica is dangerous behavior and often maintained by automatic reinforcement. We conducted a latency functional analysis (FA) using safe consumption items to verify that pica was maintained in part by automatic reinforcement and exclude participants for whom pica was likely maintained solely by attention. Next, we identified precursors to pica through a probability analysis and conducted a brief blocking assessment for participants' whose pica occurred in the alone and attention conditions of the FA. Finally, we compared blocking precursors with pica, touching an inedible item and the pica itself. Results showed that five of the six participants' pica was likely maintained by automatic reinforcement, and pica decreased during the brief blocking assessment for three of four participants. Results of the blocking comparison showed that blocking behaviors earlier in the response hierarchy was as effective as only blocking pica attempts for two participants and more effective for one participant.     

State of Innovation in Suicide Intervention Research with Military Populations

A systematic search was performed to identify active, externally funded randomized controlled trials (RCTs) that target suicidal ideation or behavior as a primary or secondary outcome among U.S. military service members, guard–reservists, and veterans. Twenty‐three studies were identified, most funded by the U.S. Department of Defense or U.S. Department of Veterans Affairs. Several innovations were identified based on departures from or modernizations of usual practices and included the targeting of suicide deaths or attempts as primary outcome, delivery of interventions through technology and/or outside clinical settings, and examinations of rarely studied treatments.     

Advancing Developmental Science via Unmoderated Remote Research with Children

ABSTRACT

This article introduces an accessible approach to implementing unmoderated remote research in developmental science – research in which children and families participate in studies remotely and independently, without directly interacting with researchers. Unmoderated remote research has the potential to strengthen developmental science by: (1) facilitating the implementation of studies that are easily replicable, (2) allowing for new approaches to longitudinal studies and studies of parent-child interaction, and (3) including families from more diverse backgrounds and children growing up in more diverse environments in research. We describe an approach we have used to design and implement unmoderated remote research that is accessible to researchers with limited programming expertise, and we describe the resources we have made available on a new website (discoveriesonline.org) to help researchers get started with implementing this approach. We discuss the potential of this method for developmental science and highlight some challenges still to be overcome to harness the power of unmoderated remote research for advancing the field.     

Causation in the Phaedo

Abstract: In the Phaedo Socrates says that as a young man he thought it a great thing to know the causes of things; but finding existing accounts unsatisfying, he fell back on a method of his own, hypothesizing that Forms are causes. I argue that part of what this hypothesis says is that certain phenomena – the ones for which it postulates Forms as causes – are the result of processes whose object was to produce them. I then use this conclusion to explain how Socrates’ discussion of causality in the Phaedo might be supposed to contribute to his final argument for immortality.     

Two Theologies of Death: Anthropological Gleanings

Theologies of death by Karl Rahner and Eberhard Jungel are closely analyzed to test the hypothesis that the coherence of Christian theological anthropology depends on holding in dialectical balance the implications of three distinct ways in which God relates to humankind (as creator, as redeemer and as eschatological consummator) held in dialectical equipoise. Connections are shown between Rahner's focus on creation/consummation (subordinating the redemption-relation) and his unintended undercutting of sola gratia ; and between Jungel's focus on creation/redemption (subordinating consummation) and his evacuating the ontological status of the creature. Four positive morals are drawn for doing anthropology.     

Developmental Changes in Strategies for Gathering Evidence About Biological Kinds

How do people gather samples of evidence to learn about the world? Adults often prefer to sample evidence from diverse sources—for example, choosing to test a robin and a turkey to find out if something is true of birds in general. Children below age 9, however, often do not consider sample diversity, instead treating non-diverse samples (e.g., two robins) and diverse samples as equivalently informative. The current study (N = 247) found that this discontinuity stems from developmental changes in standards for evaluating evidence—younger children chose to learn from samples that best approximate idealized views of what category members are supposed to be like (e.g., the fastest cheetahs), with a gradual shift across age toward samples that cover more within-category variation (e.g., cheetahs of varying speeds). These findings have implications for the relation between conceptual structure and inductive reasoning, and for the mechanisms underlying inductive reasoning more generally.
