Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired social interaction, verbal and nonverbal communication, and behaviors or interests. Besides behavioral, psychopharmacological and biomedical interventions there is increasing evidence of non-invasive treatments like neurofeedback (NFB) that can improve brain…

Executive functions (EFs) are a set of high-level cognitive processes that enable children to perform a goal-directed behaviour. During the preschool years, EFs undergo significant developmental changes. Therefore, it is crucial to have reliable measures that accurately evaluate preschoolers' EFs in preschool-aged children. The present study aimed…

The present study examined the way in which behavioural difficulties in cool and hot EFs relate to measures of cognitive and affective ToM in preschoolers. A total of 144 children between 35 and 71 months were assessed with a first-order false-belief task (measuring cognitive ToM), the Test of Emotion Comprehension (measuring affective ToM) and a…

Executive functions (EF), either conceptualized as skills involved in regulation of cognition and emotion in service of goal-oriented behavior, or reductively as working memory, flexibility and inhibitory control, are commonly invoked constructs in developmental science. Two main traditions on EFs measurement prevail, one consisting of ratings…

Process-Overlap Theory (POT) suggests that measures of cognitive abilities sample from sets of independent cognitive processes. These cognitive processes can be separated into domain-general executive processes, sampled by the majority of cognitive ability measures, and domain-specific processes, sampled only by measures within a certain domain.…

The current paper investigates the structural validity of the Children's Concentration and Empathy Scale (CCES), which was designed based on Montessori's developmental theory to assess, using teacher ratings, the coherence of attention-related characteristics (concentration, empathy, and normalization) in children from 1.5 to 12 years old. The…

We explored whether and how cognitive measures of executive function (EF) can be used to help classify academic performance in Kindergarten and first grade using nonparametric cluster analysis. We found that EF measures were useful in classifying low-reading performance in both grades, but mathematics performance could be grouped into low,…

The Head Start Family and Child Experiences Survey (FACES) and the American Indian and Alaska Native Head Start Family and Child Experiences Survey (AIAN FACES) are separate studies done successively over time. One goal for these studies is to provide a national picture of children's readiness for school. In this research brief, the authors use…

Since Miyake and his colleagues (2000) published their seminal paper on the use of confirmatory factor analysis (CFA) to parse executive function (EF), CFA methods have become ubiquitous in EF research. In their interesting and thoughtful Focus article, "Executive Function: Formative Versus Reflective Measurement," Willoughby and…

Higher-order factor analysis is a widely used approach for analyzing the structure of a multidimensional test. Whenever first-order factors are correlated researchers are tempted to apply a higher-order factor model. But is this reasonable? What do the higher-order factors measure? What is their meaning? Willoughby, Holochwost, Blanton, and Blair…

The authors of the Focus article pose important questions regarding whether or not performance-based tasks related to executive functioning are best viewed as reflective or formative indicators. Miyake and Friedman (2012) define executive functioning (EF) as "a set of general-purpose control mechanisms, often linked to the prefrontal cortex…

The primary objective of this article was to critically evaluate the routine use of confirmatory factor analysis (CFA) for representing an individual's performance across a battery of executive function tasks. A conceptual review and statistical reanalysis of N = 10 studies that used CFA methods of EF tasks was undertaken. Despite evidence of…

The focus article (Willoughby et al., 2014) (1) introduced the distinction between formative and reflective measurement and (2) proposed that performance-based executive function tasks may be better conceptualized from the perspective of formative rather than reflective measurement. This proposal stands in sharp contrast to conventional…

The current national implementation of response-to-intervention frameworks has intensified the debate regarding underlying causes of student deficits and how to best assess and intervene for them. If cognitive measures are useful to intervention planning, then experimental research should be able to demonstrate that use of cognitively focused…

Purpose: Random item generation (RIG) involves central executive functioning. Measuring aspects of random sequences can therefore provide a simple method to complement other tools for cognitive assessment. We examine the extent to which RIG relates to specific measures of cognitive function, and whether those measures can be estimated using RIG…
