Cognitive control describes the ability to use internal goals to strategically guide how we process and respond to our environment. Changes in the environment lead to adaptation in control strategies. This type of control learning can be observed in performance adjustments in response to varying proportions of easy to hard trials over blocks of…

Existing approaches in the literature on cognitive control in conflict tasks almost exclusively target the outcome of control (by comparing mean congruency effects) and not the processes that shape control. These approaches are limited in addressing a current theoretical issue--what contribution does learning make to adjustments in cognitive…

Objective: Little is known about cognition's effect on jump-landing movement patterns. Design: Participants completed three baseline cognitive tasks. Then, participants performed three jump-landing trials per condition (dual-task trials (DT)): Stroop Color Word test (SCWT), Symbol Digits Modalities test (SDMT), Brooks Visuospatial task (BVT), and…

Purpose: When speakers retrieve words, they do so extremely quickly and accurately--both speed and accuracy of word retrieval are compromised in persons with aphasia (PWA). This study examined the contribution of two domain-general mechanisms: processing speed and cognitive control on word retrieval in PWA. Method: Three groups of participants,…

It has been suggested that the Stroop task gives rise to 2 conflicts: the information conflict (color vs. word meaning) and the task conflict (name the color vs. read the word). However, behavioral indications for task conflict (reaction time [RT] congruent condition longer than RT neutral condition) appear under very restricted conditions. We…

Purpose: The pupil dilation response is sensitive not only to auditory task demand but also to cognitive conflict. Conflict is induced by incompatible trials in auditory Stroop tasks in which participants have to identify the presentation location (left or right ear) of the words "left" or "right." Previous studies demonstrated…

Cognitive flexibility (switching) and control (inhibition) are among widely accepted cognitive advantages of bilingualism. Switch Cost (SC), i.e., the time difference to complete a switch versus non-switch task, is a construct for measuring the switching ability. The need to control the interference and switching between one's languages leads to…

The study assessed the relationship among the factors of inhibition control, working memory, and cognitive flexibility in relation to cognitive development of children. A total of 30 children (17 male and 13 female) age group 6-7 years old (Mean=6.5; SD = 0.34) participated in the study. In this study, the authors have used Stroop Task, Saccadic…

Purpose: Speech recognition relies upon a listener's successful pairing of the acoustic--phonetic details from the bottom-up input with top-down linguistic processing of the incoming speech stream. When the speech is spectrally degraded, such as through a cochlear implant (CI), this role of top-down processing is poorly understood. This study…

Although many researchers theorize that primitive numerosity processing abilities may lay the foundation for whole number concepts, other classes of numbers, like fractions, are sometimes assumed to be inaccessible to primitive architectures. This research presents evidence that the automatic processing of nonsymbolic magnitudes affects processing…

Purpose: The aim of this study was to determine the impact of cognitive load imposed by a speech production task on the speech motor performance of healthy older and younger adults. Response inhibition, selective attention, and working memory were the primary cognitive processes of interest. Method: Twelve healthy older and 12 healthy younger…

The article is devoted to the issue of learning from the cognitive perspective. As life-long learning is an integral part of our modern life, the authors were attracted by the phenomenon when even young people demonstrate cognitive "resistance" to learning. This particular study is focused on cognitive destructions as challenges to…

The present behavioral study aimed to examine the impact of language control expertise on two domain-general control processes, i.e. active inhibition of competing representations and overcoming of inhibition. We compared how Simultaneous Interpreters (SI) and Highly Proficient Bilinguals--two groups assumed to differ in language control…

This study explored the relationship between schizotypy, hypomania, and indicators of creativity in 152 adult undergraduate students. We were interested in exploring a possible inverted U-shaped relationship between mental illness and creativity where moderate (vs. high or low) amounts of pathology are associated with facilitating creative…

Background: Assessment of intelligence and executive function (EF) is common in complex neuropsychiatric practice. Although previous studies have shown that EF and intelligence are related, it is unknown whether these constructs relate to one another in a similar manner across different ability groups (mild intellectual disability, borderline…
