Directional uncertainty in chase and escape dynamics.

Intercepting and avoiding collisions with moving targets are crucial skills for survival. However, little is known about how these behaviors are implemented when the trajectory of the moving target introduces variability and ambiguity into the perceptual-motor system. We developed a simple visuomotor task in which participants used a joystick to interact with a computer-controlled dot that moved along two-dimensional trajectories.

Therapeutic Approaches for ADHD by Developmental Stage and Clinical Presentation.

Attention Deficit Hyperactivity Disorder is a neurodevelopmental disorder with three presentations: inattentive, hyperactive/impulsive and combined. These may represent an independent disease entity. Therefore, the therapeutic approach must be focused on their neurobiological, psychological and social characteristics.

Clustering of neuropsychological traits of preschoolers.

Neuropsychological tests (targeting cognitive, linguistic, motor, and executive abilities) are grouped in neuropsychological domains that are thought to be stable through adulthood. However, this assumption does not always hold true, particularly during young children's early developmental phase. Here, we explored how the neuropsychological profile of typical Spanish-speaking preschoolers varied and consolidated with age.

Effects of the Age, Sex, and Maternal Education of Monolingual Spanish-Speaking Preschool Children on Oral Narrative Production.

Purpose The aim of the present cross-sectional study was to determine the effects of age, sex, and maternal education of monolingual Spanish-speaking preschoolers on both macrostructural (oral narrative quality) and microstructural measures (number of different words, communication units, mean length of utterance in both words and morphemes, and number of conjunctions) of their oral narrative production. Method A total of 277 monolingual Spanish-speaking Mexican children aged 2;06-5;11 (years;months) and divided into four age groups (ages 2, 3, 4, and 5 years) were asked to retell a fictional story from the oral narrative ability task of the . Results Appropriate internal consistency and interrater reliability were demonstrated.

Development of early numerical abilities of Spanish-speaking Mexican preschoolers: A new assessment tool.

This article presents a tool for assessing the early numerical abilities of Spanish-speaking Mexican preschoolers. The Numerical Abilities Test, from the Evaluación Neuropsicológica Infantil-Preescolar (ENI-P), evaluates four core abilities of number development: magnitude comparison, counting, subitizing, and basic calculation. We evaluated 307 Spanish-speaking Mexican children aged 2 years 6 months to 4 years 11 months.

Effect of chronic iron deficiency on neuropsychological domains in infants.

The aim of this study was to assess the effects of chronic iron deficiency on neuropsychological traits in infants. We established the nutritional iron status and assessed the neuropsychological characteristics of 58 Mexican 14- to 18-month-old infants. The Bayley Scales of Infant Development, preschool language scales and an environmental sound perception task designed expressly for the study, were used.
