Differences in decision-making development between expert and novice invasion game players

This cross-sectional study investigated the differences between young expert soccer players' (n = 55) and novice players' (n = 74) decision-making ability during performance of invasion games (ages: 7-8, 9-10, 11-12, and 13-14 years). Decision-making ability was assessed in invasion games that were appropriately modified for age and expertise. Games were modified to meet the developmental needs and previous learning of the participants, so interference between motor execution and decision making was minimized. Game performance was videotaped, and measures of cognitive components were developed from observational analysis. Decision making was measured at two levels: (a) decision making restricted to the selection of the technical-tactical skills (passing, moving with the ball, getting free, marking, tackling, double teaming, and interception) and (b) decision making in the adaptation to the tactical context of the game. Expert players remained superior in decision-making ability when variation in skill execution was controlled. Decision-making differences between levels of expertise decreased with age with regard to the first level (skill selection) and increased with age in relation to the second level (tactical-context adaptation). Findings are discussed in terms of implications for instructional focus and task design.     

The Affect in Play Scale: confirmatory factor analysis in elementary school children

The aim of this paper was to study the construct validity of the Affect in Play Scale, an empirically based measure of pretend play, in a group of 519 Italian children ages 6 to 10 years. In confirmatory factor analysis, a correlated two-factor structure with a cognitive and an affective factor was identified. Possible differences in factor scores by sex and age were investigated but no significant differences were found.     

General cognitive functioning and psycholinguistic abilities in children with Smith-Magenis Syndrome

This study is a neuropsycholinguistic research of a rare genetic syndrome with microdeletion that co-occurs with intellectual disabilities and relatively good language abilities, the Smith-Magenis Syndrome (SMS). Nevertheless, there are no cognitive and psycholinguistic profile analyses performed with Spanish population. In this sense, we characterized the cognitive and psycholinguistic profile of a sample with 9 participants with SMS (7 to 11 years of age). The cognitive and psychological profile was assessed with diverse standardized tests: Wechsler Intelligence Scale for Children - IV version, Illinois Test of Psycholinguistic Abilities and Peabody Picture Vocabulary Test. Results suggest a specific cognitive and psychological profile characterized by a low IQ and relative good abilities in integrating information, whereas attention problems and hyperactive behaviors were displayed when interacting with the child during the assessment. This work is the first evidence of the cognitive and psycholinguistic profile characterization in patients with SMS in Spain, and will help to guide a more accurate diagnosis and differential intervention in rare genetic diseases with similar cognitive and psycholinguistic profiles.     

Do adolescents who use stimulants have a different personality?

Stimulant consumption is especially important in our context because its use has greatly increased in recent years. The aim of the present study is to analyze the differences between stimulant users and nonusers (under 18 years old) in personality characteristics assessed with the MACI. The sample comprises 398 youths between 14 and 17 years old who were selected through random sampling in their homes or in recreational night spots. Results show important differences in personality features between stimulant users and nonusers. Stimulant users are characterized by having unruly, forceful, oppositional and borderline-tendency personality prototypes.     

Prevalence and differentiating aspects related to gender with regard to the bullying phenomenon in poor countries

There is a large body of scientific knowledge about school violence and bullying in Europe and some other regions of the so-called developed world. However, improvement is scarce in poor and developing regions, as in the case of Latin America and, in particular, Nicaragua. The goal of this work was to determine the prevalence of the bullying phenomenon in Nicaraguan primary schools, to analyze the eventual relationships between the different forms of violence used by the students and to explore, in relation to these aspects, the similarities and differences between boys and girls. For this purpose, we surveyed 3042 pupils of primary school (50.3% girls) using the "Cuestionario sobre Convivencia, Violencia y Experiencias de Riesgo" (COVER, in English, Questionnaire about Living Together, Violence and Risk Experiences). We found that the level of involvement in bullying is significantly higher than in developed countries, that boys are more involved than girls in verbal, physical and psychological bullying, and that there are no differences with regard to social exclusion. The results are discussed, comparing them with studies conducted in different countries but with similar methodologies.     

Factor structure analysis of the Preschool and Kindergarten Behavior Scale scores in Spanish population

Social competence and antisocial behavior in children are interesting variables for researchers and educators. Nonetheless, there are few assessment instruments capable of measuring the two constructs in small children. The aim of this study is to verify the structural validity of the Preschool and Kindergarten Behavior Scale for Teachers and Caregivers (PKBS-2), in order to determine the theoretical model that best fits the data from a Spanish sample. 1509 children from preschool education (741 males and 768 females) from 3 to 6 years old (M= 3.78; SD= 0.815) participated in the study. Data was analyzed using the Statistical Package for the Social Sciences (SPSS-15.0) and the Structural Equations Program (EQS 6.1). The resulting models of social skills and behavioral problems show adequate fit indexes, statistically significant loadings, and a high internal consistency index (Cronbach's alpha). Lastly, the structural model confirms a two-factor structure: a first factor of Social Skills, comprising three variables (social cooperation, social interaction, and social independence), and a second factor of Behavior Problems, comprising two variables (externalization and internalization of problems).     

Are indigenous personality dimensions culture specific? Philippine inventories and the five-factor model.

The authors addressed the culture specificity of indigenous personality constructs, the generalizability of the 5-factor model (FFM), and the incremental validity of indigenous measures in a collectivistic culture. Filipino college students (N = 508) completed 3 indigenous inventories and the Filipino version of the Revised NEO Personality Inventory (NEO-PI-R). On the basis of the factor and regression analyses, they concluded that (a) most Philippine dimensions are well encompassed by the FFM and thus may not be very culture specific: (b) a few indigenous constructs are less well accounted for by the FFM: these constructs are not unknown in Western cultures, but they may be particularly salient or composed somewhat differently in the Philippines; (c) the structure of the NEO-PI-R FFM replicates well in the Philippines: and (d) Philippine inventories add modest incremental validity beyond the FFM in predicting selected culture-relevant criteria.     

Do type and token effects reflect different mechanisms? Connectionist modeling of Dutch past-tense formation and final devoicing

In this paper, we show that both token and type-based effects in lexical processing can result from a single, token-based, system, and therefore, do not necessarily reflect different levels of processing. We report three Simple Recurrent Networks modeling Dutch past-tense formation. These networks show token-based frequency effects and type-based analogical effects closely matching the behavior of human participants when producing past-tense forms for both existing verbs and pseudo-verbs. The third network covers the full vocabulary of Dutch, without imposing predefined linguistic structure on the input or output words.
