Monolingual children sometimes resist learning second labels for familiar objects. One explanation is that they are guided by word learning constraints that lead to the assumption that objects have only one name. It is less clear whether bilingual children observe this constraint. In the current study, we test the hypothesis that bilingual…

We now understand that human intelligence, once thought to be determined almost solely by heredity, is malleable. In developed countries, average intelligence test scores have increased substantially since the tests began to be administered 100 years ago. In school settings, however, intelligence is often still treated as a fixed attribute that…

As we witness a push toward studying spatial reasoning as a principal component of mathematical competency and instruction in the twenty first century, we argue that enactivism, with its strong and explicit foci on the coupling of organism and environment, action as cognition, and sensory motor coordination provides an inclusive, expansive, apt,…

Humans and many other species selectively attend to stimuli or stimulus dimensions--but why should an animal constrain information input in this way? To investigate the adaptive functions of attention, we used a genetic algorithm to evolve simple connectionist networks that had to make categorization decisions in a variety of environmental…

Spatial categorization has a long history in the research of infant cognition and perception. Many conclusions are drawn from the approach wherein infants are habituated to examples of a spatial category X and then display an attention recovery (i.e., dishabituation) to a contrasting category Y. However, the distinction infants make between X and…

Two experiments investigated how preschoolers judge whether learning has occurred. Experiment 1 showed that 3- and 4-year-olds used an individual's ability to demonstrate knowledge to judge whether he/she had learned something, regardless of that individual's claim about whether he/she had learned. Experiment 2 considered whether children…

Recently, MDS has been utilized to identify and evaluate cognitive ability latent profiles in a population. However, dimension coordinates do not carry any statistical properties. To cope with statistical incompetence of MDS, we investigated the common aspects of various studies utilizing bootstrapping, and provided an R function for its…

A new probability-based standard setting technique, the Objective Borderline Method (OBM), was introduced recently. This was based on a mathematical model of how test scores relate to student ability. The present study refined the model and tested it using 2500 simulated data-sets. The OBM was feasible to use. On average, the OBM performed well…

Amartya Sen's capability approach characterizes an individual's well-being in terms of what they are able to be, and what they are able to do. This framework for thinking has many commonalities with the core ideas in career guidance. Sen's approach is abstract and not in itself a complete or explanatory theory, but a case can be…

Cognitive assessment in natural group settings facilitates data collection but poses threats to the validity. In this study, tablet-based working memory (WM) tasks, the counting span, and reading span were used in predicting 12-year-old children's (N = 837) scholastic skills and fluid intelligence in a classroom with environmental noise. WM tasks…

The purpose of this study was to investigate the contributions of general cognitive skills (working memory, inhibition, and reasoning) and metalinguistic awareness to young children's character reading. One hundred eighty-nine Chinese children, aged from 60 to 78 months, were administered with measures of character recognition, language,…

High rates of attention deficit/hyperactivity disorder (ADHD) comorbidity have been described in autism spectrum disorder (ASD). This study searched for predictors at toddlerhood of the severity of ADHD symptoms at adolescence. The study included 65 participants, (mean age = 13:8 year), diagnosed with ASD at toddlerhood. Participants underwent a…

This study aims to assess the perception that 9th year students have about some key concepts related to the "science of risk" and to evaluate their ability to identify and classify the natural and mixed risks with a greater probability of occurrence, both at national level and in the Metropolitan Area of Porto (MAP). A questionnaire was…

Regarding research on inclusive education, it is unknown whether differences in classroom composition provide unequal opportunities for educational outcomes of students with special educational needs (SEN). We investigated effects of student characteristics and classroom composition on reading achievement and social participation of SEN students.…

In the current study, we investigated the ways in which the acquisition and transfer of spatial knowledge were affected by (a) the type of spatial relations predominately experienced during learning (routes determined by walkways vs. straight-line paths between locations); (b) environmental complexity; and (c) the availability of rotational…
