Neurobehavioral functioning in children with fetal alcohol spectrum disorder.

Neurobehavioral functioning of 50 Canadian children diagnosed with Fetal Alcohol Spectrum Disorder (FASD) was evaluated. The aims of this study were to identify specific areas of weakness in neurobehavioral functioning, to examine whether neurobehavioral functioning was related to various predictor variables, and to determine which measures differentiated between children given a brain score of 2 (possible dysfunction) and 3 (probable dysfunction). Participants displayed difficulties with many aspects of intelligence, memory, executive functioning, and attention. Measures of Full scale and Verbal IQ, as well as memory for faces and numbers differentiated between children with a brain 2 and 3 ranking. An interesting pattern of strengths and weaknesses emerged as well as significant differences related to ethnic background, gender, and age. Aboriginal children and Caucasian children with FASD do not appear to show the same pattern of strengths and weaknesses in neurobehavioral functioning.     

The rhythm aftereffect: support for time sensitive neurons with broad overlapping tuning curves

Ivry [Ivry, R. B. (1996). The representation of temporal information in perception and motor control. Current Opinion in Neurobiology, 6, 851-857.] proposed that explicit coding of brief time intervals is accomplished by neurons that are tuned to a preferred temporal interval and have broad overlapping tuning curves. This proposal is analogous to the orientation selective cells in visual area V1. To test this proposal, we used a temporal analog to the visual tilt aftereffect. After adapting to a fast auditory rhythm, a moderately fast test rhythm (400 ms between beats) seemed slow and vice versa. If the speed of the adapting rhythm was made too disparate from speed of the test rhythm the effect was diminished. The effect occurred whether the adapting and test stimuli were presented to the same or different ears, but did not occur when an auditory adapting rhythm was followed by a visual test rhythm. Results support the proposition that explicit time information is coded by neural units tuned to specific temporal intervals with broad overlapping tuning curves. In addition, it appears that there is a single timing mechanism for each incoming sensory mode, but distinct timers for different modes.     

From a necessary being to god

Not a lot of work on theistic arguments has been devoted to drawing connections between a necessary being and theistic properties. In this paper, I identify novel paths from a necessary being to certain theistic properties: volition, infinite power, infinite knowledge, and infinite goodness. The steps in those paths are an outline for future work on what William Rowe (The Cosmological Argument, 1975, p. 6) has called “stage II” of the cosmological argument.     

Revised Craig Lipreading Inventory.

The two purposes of this study were to shorten the Craig Lipreading Inventory without affecting its reliability and validity and to establish normative data on the revised version. The full inventory was administered to 75 children. By item analysis, half of the items were selected to comprise the brief version; both versions were administered to another group of 75 children. Scores on the two versions correlated (.91 and .92, respectively, for Word Forms A and B and .97 and .95, respectively, for Sentence Forms A and B), thereby substantiating the construct validity of the briefer version. There was significantly high intertest reliability for the Word Forms (.80) and Sentence Forms (.82) of the briefer inventory. Normative data were computed for each age group. This briefer version is a temporally efficient tool for evaluating lipreading ability of children.     

An Ounce of Prevention: A Model for Working with Couples At-Risk for Battering

Literature on preventing spousal battering before it starts is virtually non-existent. This article describes a prevention of abuse program that targets couples at-risk for battering. At-risk couples and the process of engaging them in couples counseling are described. The prevention model is based on a Bowenian approach that focuses on partner differentiation and reducing emotionality and promoting rational thinking. It is assumed that increasing differentiation decreases the risk of spousal battering. The various techniques used to facilitate differentiation are presented as well as a case example illustrating a successful prevention of abuse experience.     

Correlation between Changes in Stress-Induced Corticosterone Secretion and GR mRNA Levels

The current study was conducted to determine the potential relationship between stress-induced corticosterone secretion and corticosteroid receptor mRNA levels after 5 days of intermittent stress. In particular, we were interested in the rate at which animals terminate a stress response, and how this termination may be altered by repeated stress. Adult male Sprague-Dawley rats were subjected to either 5 days of restraint stress or 5 days of an unpredictable stress paradigm. Restraint-stress induced corticosterone secretion was measured on Days 1 and 5 in both groups, and animals were killed on Day 6. Glucocorticoid receptor (GR), and mineralocorticoid (MR) mRNA levels were determined using in-situ hybridization techniques. Five days of restraint stress caused an habituation of the plasma corticosterone response to stress measured 60 and 90 min post-stress initiation; this pattern of corticosterone secretion was not observed in the animals subjected to unpredictable stress. Five days of either stress paradigm did not alter MR mRNA levels measured within the hippocampus or GR mRNA levels within the hippocampus or the medial parvocellular division of the paraventricular nucleus of the hypothalamus (mpPVN). However, an individual's GR mRNA levels measured within the CA1/2 region of the hippocampus and the mpPVN were significantly correlated with the degree of habituation of the corticosterone response to stress measured on Day 5. This suggests that an increase in the rate of termination of the stress response and levels of GR within the hippocampus and mpPVN may be functionally related.     

Action and emotion in everyday life

This study of naturally occurring behaviour employed a "beeper technique" to investigate the actions carried out by 152 subjects in eight different groups, viz. adult students, employed students who were also parents, unemployed, art students, doctoral students, alcoholics, retired people and a control group. Actions were sampled for seven subsequent days, five times per day between 8 a.m. and 10 p.m. at randomly selected occasions. Each action was rated on a number of variables, shortly after it was sampled (median delay approximately 10 min). Some of the findings were: Time allocation corresponded well with national estimates. Being under situational control was highly aversive. Instrumental and consummatory orientations correlated positively. The background variables were, on the whole, only rather weakly related to action ratings, but it was found that women and retired persons tended to report a higher level of well-being.     

Parametric and bootstrap approaches to repeated measures designs

Recently, a nonparametric technique called bootstrapping has been recommended over the more well-known analysis of variance (ANOVA) for analyzing repeated measures data. Advocates cite as bootstrap’s advantages over ANOVA the fact that the former uses distributional information and is free of normal theory assumptions. The present study used a computer simulation to compare the two techniques calculated using data sampled from normal and nonnormal distributions. The parametric test had adequate control of Type I error rates; the nonparametric test had overly liberal Type I error rates and therefore is not recommended.     

Predicting Deliberate Self‐Harm in Adolescents: A Six Month Prospective Study

Few studies have investigated the extent to which psychosocial/psychological factors are associated with the prediction of deliberate self‐harm (DSH) among adolescents. In this study, 737 pupils aged 15–16 years completed a lifestyle and coping survey at time one and 500 were followed up six months later. Six point two percent of the respondents (n = 31) reported an act of DSH between Time 1 and Time 2. In multivariate analyses, worries about sexual orientation, history of sexual abuse, family DSH, anxiety, and self‐esteem were associated with repeat DSH during the course of the study, but history of sexual abuse was the only factor predictive of first‐time DSH. The findings suggest that school‐based programs focused on how young people cope with psychosocial stressors may offer promise.
