Working memory, response inhibition, and within-subject variability in children with attention-deficit/hyperactivity disorder or reading disorder

Behavioral inhibition in children with learning disabilities

“…Tasks measuring behavioral inhibition, always implicate also other executive functions (e.g., working memory) or other lower cognitive processes (van der Sluis, de Jong, & van der Leij, 2007). These results underline the need to control for this task impurity (e.g., Van De Voorde et al, 2010), as was done in our study by choosing for a task with only one go and one no-go stimulus.…”

“…However, other studies found no differences between both groups (e.g., Reiter, Tucha, & Lange, 2005;Schmid et al, 2011). For instance, Van De Voorde, Roeyers, Verte, and Wiersema (2010) found no behavioral inhibition problems, as measured by a Go/no-go task, in RD when a baseline measure of functioning was taken into account.…”

“…The concept of a Go/no-go task with three different modalities was based on Van De Voorde et al (2010). The task was programmed in Affect 4.0 (Hermans, Clarysse, Baeyens, & Spruyt, 2005).…”

“…In that way, the influence of other cognitive processes was minimized (Van De Voorde et al, 2010). Each condition consisted of 45 go trials (the picture of a bird in the first modality, letter 'a' in the second and number '1' in the third) and 15 no-go trials (a butterfly, 'm' and '6', respectively).…”

“…Commission errors were considered as measure of behavioral inhibition, while MRT mainly measures response speed (Van De Voorde et al, 2010). Commission errors are those errors where the child pushed the spacebar during a no-go trial.…”
