RESUMO

Working memory (WM) and inhibitory control (IC) play a crucial role in learning during early childhood. The literature suggests a non-linear developmental trajectory of executive functions (EFs) with varied results according to gender, usually attributed to environmental factors. However, there is insufficient and inconclusive data on whether this pattern is reproduced in the Latin American preschool population since most studies have been conducted in English-speaking, European, and Asian environments. Thus, objectively comparing children's executive performance across diverse international geographical contexts becomes challenging. This study aimed to conduct a cross-sectional analysis of the performance in WM and IC of 982 Ecuadorian preschoolers aged between 42 and 65 months (M = 53.71; SD = 5.714) and belonging to medium-high, medium, and low-medium socioeconomic strata. The participants consisted of 496 boys (M = 53.77; SD = 5.598) and 486 girls (M = 53.65; SD = 5.834), representing nine cities in Ecuador. To assess the effect of age and gender on performance in these two domains, the sample was divided into four 6-month age intervals. Two tests were administered to the participants, and a survey was conducted with 799 of their usual caregivers. Viewing the cross-sectional mean scores of the WM and IC tests as a temporal continuum reveals an upward trend in each age interval studied. Girls outperformed boys on the IC test, showing statistically significant differences in the earliest age interval. The gender differences in executive performance reported in the literature emphasize the need to explore the modulating effect of environmental variables on early childhood development. This information could offer valuable insights for adapting and optimizing cognitive and didactic strategies in early childhood tailored to the characteristics and needs of the preschool population.

RESUMO

The Personality Assessment Inventory (PAI; Morey, 1991, 2007) is among the most important personality and psychopathology assessment tools. However, its psychometric properties in the Spanish-speaking prison population have not yet been studied. We aimed to explore the factor structure of the Spanish adaptation of the PAI (Ortiz-Tallo et al., 2011) in an Ecuadorian sample of 811 convicted men using exploratory structural equation modeling, with the further objective of confirming its internal consistency. Hoelzle and Meyer (2009) identified three dimensions that are highly congruent across samples: general distress, elevated mood and dominance, and substance abuse and psychopathy. Taking these findings and the internalizing and externalizing dimensions (Ruiz & Edens, 2008) as a theoretical basis, three- and two-factor models were tested for the 22 scales and 11 clinical scales, respectively. We also tested four- and three-factor models that grouped the scales related to substance abuse as an independent factor, leaving intact the distribution presented by the remaining scales in the previous models. Although the original models showed a good fit, the 4- and 3-factor models obtained significantly better fit indexes. With respect to reliability, the Cronbach's alpha coefficients ranged from .49 to .89. This version shows acceptable psychometric properties in correctional settings.

RESUMO

La investigación actual en el campo de la violencia de pareja es escasa en lo que se refiere al papel del procesamiento emocional de los maltratadores. Sin embargo, ningún estudio ha investigado en la misma muestra la capacidad de reconocer las emociones y la influencia de las emociones en los aspectos atencionales. El objetivo de este estudio es investigar en una muestra de maltratadores la capacidad de reconocer las emociones de fotografías estandarizadas y analizar la interferencia de las palabras con contenido emocional en una tarea atencional. La muestra consistió en 90 hombres condenados por violencia de pareja y 77 hombres condenados por otros delitos. Se evaluaron las características sociodemográficas asociadas a nuestra muestra y el procesamiento emocional de las expresiones faciales con la prueba de Ekman y la Tarea Stroop Emocional, diseñada específicamente para evaluar el procesamiento emocional en situaciones de violencia contra la pareja. Los resultados mostraron un mejor reconocimiento emocional de los maltratadores en las emociones faciales de enfado y sorpresa. Para el procesamiento de palabras con contenido emocional, las diferencias no fueron estadísticamente significativas.

Current research in the field of intimate partner violence has been scarce as regards the role of emotional processing in abusers. Nevertheless, no study has investigated the ability to recognize emotions and the influence of emotions on attention-related aspects among the same sample. The aim of this study is to investigate the ability to recognize emotions in standardized photographs, and to analyze the interference that words with emotional content exert on an attention task in a sample of abusers. The sample consisted of 90 men convicted of intimate partner violence and 77 men convicted of other crimes. Demographic characteristics associated to the sample were evaluated, as were emotional processing of facial expressions with the Ekman Test and the Emotional Stroop task, specifically designed to assess emotional processing in situations of intimate partner violence. The results showed better emotional recognition among abusers in the recognition of facial emotions of anger and surprise. As for the processing of words with emotional content, differences were not statistically significant.
