Development of temporal patterning and vocal hesitations in spontaneous narratives

Narratives were told aloud by 12 boys and 12 girls at each of seven age levels in response to nine cartoon pictures. Speech rate increased with age, due to corresponding decreases in both legnth and frequency of unfilled pauses (UPs), although the two measures were themselves uncorrelated. Parenthetical remarks (PRs) increased with age, while repeats (Rs) decreased. Location of UPs (81% before function words) was stable over age levels. Comparisons with other experiments are made. Interrelationships of speaking and thinking are discussed in terms of the cognitive and linguistic functions of length and frequency of UPs, respectively. Theories that neglect multiple psychological determinants of speech behavior and/or concentrate on only one level or unit of encoding are rejected as inadequate.     

The War Between Faith and Fact

Is there a war going on between science and religion or not? The Center for Theology and the Natural Sciences and many other bridge-building advocates deny that a war must be fought between genuine science and authentic faith. Yet, a new book, Faith vs. Fact, by Jerry Coyne, launches a new attack against those with faith in God. This essay asks whether such an attack comes from genuine science or from scientism—a materialist ideology that claims rational science as its ally.     

Francis Collins,the Skeptics,and Evidence for God

Skeptical Inquirer magazine has published an attempted refutation of Francis Collins' book, The Language of God. The refutation argues that Collins lacks scientific evidence for God and that Collins actually appeals not to evidence, but to personal belief. In refutation of this refutation, Ted Peters argues that Collins plays completely within the rules of scientific discourse while providing rational evidence—though not conclusive proof—for the existence of God as creator and moral lawgiver.     

The Use of the Devereux Scales of Mental Disorders in the Assessment of Attention-Deficit/Hyperactivity Disorder and Conduct Disorder

The present study was designed to gather validity data on the Devereux Scales of Mental Disorders (DSMD) for distinguishing among children and adolescents with Attention-Deficit/Hyperactivity Disorder (ADHD; N = 32), Conduct Disorder (CD; N = 34), or no clinical diagnosis (NC; N = 65). Three types of indicators were compared: (a) DSMD scale, composite, and total scores, (b) the number of ADHD or CD-related items endorsed, and (c) diagnostic efficiency statistics (e.g., sensitivity, positive and negative predictive power). The clinical groups did not differ significantly from each other, but both were significantly higher than the NC group on all DSMD scales. Moreover, there were significant differences between the ADHD and the CD groups on the number of respective ADHD and CD-related items endorsed. A cut-off of seven to eight items yielded the best discrimination between the two diagnostic groups. Diagnostic efficiency statistics indicate that the DSMD may be effective at differentiating between similar disruptive behavior disorders.     

Flashing the Yellow Traffic Light: Choices Forced Upon Us by Gene Editing Technologies

The 2018 birth of two designer babies in China has sparked an immediate global controversy over the ethics of gene editing. For the longer range future, however, we must assess how CRISPR/Cas9, like so many other new bio-technologies, is forcing choice—moral choice—on a large scale. Gene editing for purposes of medical therapy, human enhancement, engineering of future children, and even creating a posthuman species, confront our society with the inescapable necessity of making moral choices. The task for churches in partnership with universities is not to decide in advance what is right or wrong. Rather, it is to prepare our people to make responsible choices.     

Amygdala–orbitofrontal connectivity predicts alcohol use two years later: a longitudinal neuroimaging study on alcohol use in adolescence

This study tested the relation between cortical–subcortical functional connectivity and alcohol consumption in adolescents using an accelerated longitudinal design, as well as normative developmental patterns for these measures. Participants between ages 8 and 27 completed resting‐state neuroimaging scans at two time points separated by two years (N = 274 at T1, N = 231 at T2). In addition, participants between ages 12 and 27 reported on recent and lifetime alcohol use (N = 193 at T1, N = 244 at T2). Resting‐state connectivity analyses focused on amygdala–orbitofrontal connectivity given prior research linking reduced coupling between these regions to alcohol use. Mixed model analyses revealed that age had a cubic relationship with alcohol use, with little to no use in childhood, steep increases in adolescence and leveling off in adulthood. No age effects were found for amygdala–OFC connectivity. Prediction analyses showed that left amygdala–orbitofrontal connectivity at the first time point predicted recent and lifetime alcohol use two years later. There was no evidence for the reversed relation, suggesting that brain connectivity measures precede explorative risk‐taking behavior in adolescence, possibly because decreased subcortical–frontal connectivity biases towards more explorative or risky behavior.
