Reliability and Validity of Behavior Problem Checklists as Measures of Stable Traits in Low Birth Weight, Premature Preschoolers

Mothers, teachers, and assistant teachers completed the Richman Behavior Checklist (BCL) at ages 2 and 3 years and the Achenbach Child Behavior Checklist for Ages 2-3 (CBCL 2-3) at 3 years for a large sample of low birth weight, premature children. Interinstrument correlations for total scores were moderate, higher for teachers and assistant teachers than for mothers, with moderate temporal stability for BCL scores. Interrater agreement for either total scores or classifications of clinically significant scores was moderately high between teachers and assistant teachers only, and children identified as disturbed by mothers versus teachers represent almost nonoverlapping groups. Furthermore, many more children were identified as disturbed using the BCL. The most powerful predictors of mothers' total CBCL 2-3 scores were HOME Inventory scores and self-reported depression. The use of these scales in clinical and research contexts is discussed.     

Maturation of cognitive processes from late childhood to adulthood

To characterize cognitive maturation through adolescence, processing speed, voluntary response suppression, and spatial working memory were measured in 8- to 30-year-old (N = 245) healthy participants using oculomotor tasks. Development progressed with a steep initial improvement in performance followed by stabilization in adolescence. Adult-level mature performance began at approximately 15, 14, and 19 years of age for processing speed, response inhibition, and working memory, respectively. Although processes developed independently, processing speed influenced the development of working memory whereas the development of response suppression and working memory were interdependent. These results indicate that processing speed, voluntary response suppression, and working memory mature through late childhood and into adolescence. How brain maturation specific to adolescence may support cognitive maturation is discussed.     

Restricted processing of simultaneously presented brightness and pattern stimuli in pigeons

Performance during simultaneous matching-to-sample was assessed in pigeons presented with element and compound visual samples. In Experiment 1, pigeons were trained with a symbolic matching procedure, in which different pairs of colored comparison cues presented on side keys were mapped onto a bright or dim houselight as one pair of sample stimuli and onto vertical and horizontal lines on the center key as a second pair of sample stimuli. They were then tested with houselight-line compound samples. It was found that matching accuracy for lines was significantly diminished with compound samples relative to element samples. Conversely, house-light intensities were matched as well with compound samples as with element samples. In Experiment 2, a similar effect was found with pigeons that had been trained to match only line samples. In Experiment 3, it was discovered that sample duration had no influence on the matching deficit found with lines following compound samples in birds either trained or not trained to match houselight intensities. These results, taken in combination with recent findings from experiments with auditory-visual compounds, suggest a restricted processing account of pigeon processing of simultaneously presented stimuli from different sources.     

Moderate level alcohol during pregnancy, prenatal stress, or both and limbic-hypothalamic-pituitary-adrenocortical axis response to stress in rhesus monkeys

This study examined the relationship between moderate-level prenatal alcohol exposure, prenatal stress, and postnatal response to a challenging event in 6-month-old rhesus monkeys. Forty-one rhesus monkey (Macaca mulatta) infants were exposed prenatally to moderate level alcohol, maternal stress, or both. Offspring plasma cortisol and adrenocorticotrophic hormone (ACTH) were determined from blood samples before maternal separation and after separation. Behavioral observations were made repeatedly across separation. Moderate-level prenatal alcohol exposure was associated with significantly higher plasma ACTH response to maternal separation. Offspring exposed to prenatal alcohol, prenatal stress, and prenatal alcohol and stress showed reduced behavioral adaptation to stress compared with controls. Baseline, 2-hr, and 26-hr plasma ACTH levels were intercorrelated and predicted behavior during separation.     

Fostering complex problem solving for diverse learners: engaging an ethos of intentionality toward equitable access

Complex problem solving is an effective means to engage students in disciplinary content while also furnishing critical non-cognitive and life skills. Despite increased adoption of complex problem-solving methods in K-12 classrooms today (e.g., case-, project-, or problem-based learning), we know little about how to make these approaches accessible to linguistically and culturally diverse (LCD) students. In this paper, we promote a conceptual framework, based on an ethos of intentionality, that supports culturally responsive teaching (CRT). We provide specific questions to guide teachers’ implementation of an ethos of intentionality, through critical reflection and meaningful action, and discuss a framework for culturally relevant practice that operationalizes key central tenets (e.g., high expectations, cultural competence, and critical consciousness). Finally, we include strategies that can help teachers and designers translate the principles of the CRT framework into action with a specific focus on complex problem solving in classrooms.

     

The Role of Epistemic Emotions in Personal Epistemology and Self-Regulated Learning

The purpose of this article is to delineate the role of epistemic emotions in personal epistemology and self-regulated learning (SRL). We first review important tenets of personal epistemology and SRL and then present a model of SRL that situates personal epistemology within that model. We then define epistemic emotions, describe under what conditions epistemic emotions arise, and delineate how these emotions may facilitate or constrain learning processes and learning outcomes. Specifically, we present five antecedents to epistemic emotions and five consequences of those emotions during learning. The five antecedents are control, value, novelty, complexity, and achievement or impasses of epistemic aims. The five consequences are effects on planning and goal setting, motivation, cognitive and metacognitive strategies, learning outcomes, and revisions to antecedents. We end with a discussion of educational implications and future directions for research.     

Achieving Cultural Competency: Assessment of US-Based Counselor Educators Instructing Internationally

This article presents the outcomes of a qualitative investigation addressing the global exchange of counselor education. Findings delineate key traits and behaviors applied by counselor educators and counseling psychologists in cross-cultural exchanges. Personal traits noted by educators as essential for international exchanges included flexibility, respect, openness to learning, and passion for the experiences provided by international travel. Factors that increased cultural competency were cited as communication skills, increased comprehension of the context, and understanding of the counseling profession within the culture.     

Epistemic profiles and self-regulated learning: Examining relations in the context of mathematics problem solving

Relations were examined between epistemic profiles, regulation of cognition, and mathematics problem solving. Two hundred sixty-eight students were sampled from undergraduate mathematics and statistics courses. Students completed inventories reflecting their epistemic profiles and learning strategies, and were profiled as rational, empirical, or both. Based on their profiles, 24 students participated in two problem-solving sessions. Episodes were coded for planning, monitoring, control, use of empirical and rational argumentation, and justification for solutions. For both self-reported metacognitive self-regulation and regulation of cognition during problem solving, students profiled as rational had the highest self-reported mean and actual frequency of regulation of cognition compared to students profiled as predominantly empirical. Moreover, students profiled as predominantly rational correctly solved more problems than the other two groups. Finally, students’ approaches to problem solving were consistent with their epistemic profiles. Relations are discussed in the context of various theoretical frameworks.     

Vocabulary and text comprehension levels: what should be considered in assessments?

Abstract

Text comprehension comprises processes that work interactively to create a situation model of a text. Three hundred and one students from 12 Estonian schools were assessed to examine the relations between vocabulary and different text comprehension levels and to detect students’ individual profiles in these skills. Both variable- and person-oriented approaches were used to analyse overall patterns in the data as well as to make inferences regarding students’ individual differences. Vocabulary was found to have the strongest influence on inferential and literal comprehension, whereas evaluative comprehension was slightly less related to vocabulary. Person-oriented approaches revealed different patterns in students’ vocabulary and comprehension skills. Individual differences in vocabulary and comprehension levels emphasise the need to assess students’ comprehension with multidimensional tests aimed at determining the shortcomings in comprehension components and tracking students’ developmental changes.     

Effects of resistance training on expression of IGF-I splice variants in younger and older men

Insulin-like growth factor-I (IGF-I) and its splice variants Insulin-like growth factor-I isoform Ea (IGF-IEa) and mechano growth factor (MGF) may play an important role in muscular adaptations to resistance training (RT) that may be modulated by ageing. It has been suggested that IGF-I induces cellular responses via AKT8 virus oncogene cellular homolog (Akt) and Extracellular signal-regulated kinase (Erk) signalling pathways. Therefore, resistance exercise-induced changes in skeletal muscle IGF-IEa and MGF messenger ribonucleic acid (mRNA), and MGF, Erk1/2, Akt and p70S6K protein expression were investigated before and after 21 weeks of RT in younger (YM, 20–34 yrs., n?=?7) and older men (OM, 51–71 yrs., n?=?10). Experimental resistance exercises (RE) of 5?×?10 repetition maximum leg presses were performed pre- and post-RT. Muscle biopsies were obtained before and 48?h after REs, to study the late response to muscle loading. The muscle proteins or mRNAs of interest were not systematically influenced by the REs or RT, except for MGF mRNA expression which was increased (p?相似文献
