A new model of sensorimotor coupling in the development of speech

We present a computational model that learns a coupling between motor parameters and their sensory consequences in vocal production during a babbling phase. Based on the coupling, preferred motor parameters and prototypically perceived sounds develop concurrently. Exposure to an ambient language modifies perception to coincide with the sounds from the language. The model develops motor mirror neurons that are active when an external sound is perceived. An extension to visual mirror neurons for oral gestures is suggested.     

Treatment of children with ADHD: psychopedagogical program at school versus psychostimulant medication

This study examined the impact of medication management compared to a psycho-educational program on parent and teacher ratings of children with combined type ADHD. The study lasted 14 weeks and included 50 children. 17 children took medication, 17 received psycho-educational intervention, and 16 children were assigned to the control group. The measures used were the IOWA Conners Scale, the School Problem Inventory, the Abbreviated Conners, and the DSM-IV Inattention-Disorganization and Hyperactivity-Impulsivity rating scales. Regarding teacher ratings, improvements were observed on: a) inattention and school problems in the medication group versus the control group; and b) hyperactivity symptoms in the psycho-pedagogical group versus the control and medication groups. Regarding to parent ratings, improvements were observed on: a)inattention in the psycho-pedagogical group versus the control and medication groups; and b) hyperactivity symptoms in the psycho-pedagogical group versus the control and the medication groups.     

Role of cholinergic system on the construction of memories: taste memory encoding

There is a large body of evidence suggesting that cholinergic activity is involved in memory processes. It seems that cholinergic activity is essential to learn several tasks and recent works suggest that acetylcholine plays an important role during the early stages of memory formation. In this review, we will discuss the results related to taste memory formation, focusing particularly on the conditioned taste aversion paradigm. We will first give evidence that nucleus basalis magnocellularis is involved in taste memory formation, due to its cholinergic projections. We then show that the cholinergic activity of the insular (gustatory) cortex is related to the taste novelty, and that the cholinergic signals initiated by novelty are crucial for taste memory formation. Then we present recent data indicating that cortical activation of muscarinic receptors is necessary for taste trace encoding, and also for its consolidation under certain circumstances. Finally, interactions between the cholinergic and other neuromodulatory systems inducing intracellular mechanisms related to plastic changes will be proposed as important processes underlying gustatory memory trace storage.     

Incarcerated adolescent girls: personality, social competence, and delinquency

The aim of this study was to gain greater insight into the relationship of delinquency to personality and social competence in incarcerated girls. It was hypothesized that agreeableness and conscientiousness would correlate negatively with delinquency, and that the sensation-seeking aspect of extroversion would correlate positively. Two theoretical views were used to predict the relationship between social competence and delinquency: (a) delinquency as an expression of lack of social competence (i.e., social deficit), and (b) delinquency as socially competent and rationally analyzed behavior. The first view implies a negative correlation between delinquency and social competence, while the second indicates a positive one. The participants were thirty-three 12- to 18-year-old incarcerated girls. An adaptation of the Self-Reported Delinquency Scale was used for measuring delinquency; personality was measured using the Five-Factor Personality Inventory; and the Scale for Interpersonal Behavior was used to measure social competence. Agreeableness was not found to correlate with the overall delinquency score or with any specific type of delinquency or crime. The more crimes the girls reported, the less conscientious they were, and the more neurotic and open they were. The correlation between delinquency and extroversion was not statistically significant. A higher level of delinquency was accompanied by higher social competence when negative self-assertion was required (i.e., a low level of tension was felt in expressing negative feelings that were appropriate to the situation). In other social situations, however, the girls reported more situation-inappropriate feelings of tension. It was concluded that some personality factors and aspects of social competence can predict delinquency.     

COVID-19 Vaccination Acceptance: A Case of Interplay Between Political and Health Dimensions

Vaccines are essential for the eradication of diseases. Yet for many reasons, individuals do not embrace them completely. In the COVID-19 pandemic and with the possibility of the Brazilian population's immunization against the disease, both political and health-related dimensions might have had a role in individual COVID-19 vaccination acceptance. In two studies (n = 974), we tested the hypothesis that participants' vaccination acceptance is related to their past vote in the 2018 Brazilian presidential election (being or not being a Jair Bolsonaro voter) and their different levels of perceived vulnerability to disease (PVD). We further tested whether Bolsonaro's opposition or ambiguous messages towards vaccination (vs. control) increased vaccination rejection among those who have (vs. have not) voted for him and who are low (vs. high) in PVD. Results show that Bolsonaro (vs. non-Bolsonaro) voters accepted less vaccination, with higher rejection rates when participants expressed low (vs. high) PVD. Also, when primed either with Bolsonaro's opposed or ambiguous messages towards COVID-19 vaccination, such participants accepted less vaccines (vs. participants primed with neutral information). These findings are the first to show that the COVID-19 vaccine acceptance is related to their past vote and leadership influence but also different levels of perceived vulnerability to disease.     

In defense of strategic therapy

The practice of strategic therapy has raised a number of critical issues and has stimulated criticism of various sorts. Among the criticisms leveled at strategic therapy are that it involves the taking of too many risks, that it is deceptive, that it is controlling and manipulative, that it is disrespectful, and that it is superficial and narrow. Each of these five major areas of concern is discussed and addressed with case examples to illustrate a rationale and justification for the use of these less conventional methods.     

Gender differences in attributions about microcomputer learning in elementary school

To investigate whether girls' attributions about computer use were more likely to follow a pattern of learned helplessness, boys' and girls' attributions about a computerized drill-and-practice task and a tutorial program were assessed. Factor analysis of responses on an attribution questionnaire revealed three factors that differed across gender and across task. Multiple regression, using exposure time, group size, attributions, and interactions to predict posttest scores, showed different patterns for boys and girls and between tasks. For the drill-and-practice task, girls benefited from increased exposure time, and attributions to ease of task and ability predicted performance for both boys and girls. For the tutorial task, increased exposure time did not benefit either sex. Girls, however, benefitted from working in larger groups, while boys benefitted from working in smaller groups. Attributions to luck, as well as perceptions of ability and ease of task, predicted posttest scores. However, for girls, attributions to luck predicted higher scores, while for boys, attributions to luck were negatively correlated with performance. Implications for including appropriate feedback to encourage a mastery approach in computer learning, as well as optimal group size and group composition for positive attributional style and academic success, are discussed.This research was supported by Concordia University and the Fonds Pour la Formation des Chercheurs et l'Aide a la Recherche (Grant EQ-2951), Government of Quebec, Canada.The authors wish to thank Ms. Patricia Peters for assistance with the statistical analysis, and Dr. Philip Abrami, for his contribution to the project.     

The CODE: A revised battery for coping and defense and its relations to subjective health

A condensed test battery (the CODE) based on the Utrecht Coping List (UCL) and part of the Defense Mechanisms Inventory (DMI) has been developed to assess coping and defense in large population studies. It was tested for reliability and validity in students and back pain patients. Principal components factor analysis of the subscales of the UCL and DMI in the student sample revealed two coping clusters: “Instrumental mastery-oriented coping” and “Emotion-focused coping” and two defensive clusters: “Cognitive defense” and “Defensive hostility”. “Instrumental mastery-oriented coping” was negatively related to subjective health complaints measured with Ursins Health Inventory (UHI). The back pain patients were clearly different from the students, using less coping and more defensive strategies. They had more subjective health complaints that showed negative correlations with “Instrumental mastery-oriented coping”. The CODE is a comprehensive battery that may be valid for large population studies of psychological determinants of muscle pain and other subjective health problems.
