Abstract

Executive Functions comprise a range of neuropsychological processes related to intentional behavior and cognitive control. There are several theoretical models defining and explaining the concept of Executive Functions. Most of these models consider that the term Executive Functions encompasses cognitive process as working memory, cognitive flexibility, inhibitory control and other complex functions as planning, problem-solving and abstract reasoning. Other models argue that motivational and emotional functions, such as affective decision-making, reside under the concept of Executive Function. Much evidence supports how complex cognitive functions are related to the physiological activity of brain networks, including the frontal cortex and its connections with subcortical structures. Several psychiatric disorders related to impairment in these brain networks (eg., bipolar disorder, schizophrenia, ADHD, obsessive-compulsive disorder, and drug addiction) leading to deficits in Executive Functions. These cognitive deficits affect patients’ everyday functioning, worsening the clinical course of the disease. For example, deficits in Executive Functions are related to suicide behavior in bipolar disorder patients. Furthermore, these deficits also relate to obesity, a lack of adherence to treatment and an underperformance in the workplace and educational settings. The understanding of the role of deficits in Executive Functions, including its neurobiological basis, developmental trajectories, and relationship with clinical outcomes, is fundamental to improve clinical management of psychiatric patients. This research topic includes 13 articles with interdisciplinary contributions related to the understanding of the deficits in Executive Functions and its relationship with clinical manifestations in psychiatric disorders.

Abstract

Executive function refers to the goal-oriented regulation of one’s own thoughts, actions, and emotions. Its importance is attested by its contribution to the development of other cognitive skills (e.g., theory of mind), social abilities (e.g., peer interactions), and academic achievement (e.g., mathematics), and by the consequences of deficits in executive function (which are observed in wide range of developmental disorders, such as attention-deficit hyperactivity disorder and autism). Over the last decade, there have been growing interest in the development of executive function, and an expanding body of research has shown that executive function develops rapidly during the preschool years, with adult-level performance being achieved during adolescence or later. This recent work, together with experimental research showing the effects of interventions targeting executive function, has yielded important insights into the neurocognitive processes underlying executive function. Given the complexity of the construct of executive function, however, and the multiplicity of underlying processes, there are often inconsistencies in the way that executive function is defined and studied. This inconsistency has hampered communication among researchers from various fields. This Research Topic is intended to bridge this gap and provide an opportunity for researchers from different perspectives to discuss recent advances in understanding childhood executive function. Researchers using various methods, including, behavioral experiments, neuroimaging, eye-tracking, computer simulation, observational methods, and questionnaires, are encouraged to contribute original empirical research. In addition to original empirical articles, theoretical reviews and opinions/perspective articles on promising future directions are welcome. We hope that researchers from different areas, such as developmental psychology, educational psychology, experimental psychology, neuropsychology, neuroscience, psychiatry, computational science, etc., will be represented in the Research Topic.
