Purpose: The current project aimed to examine the effects of two experimental cognitive-linguistic paradigms, the Stroop task and a primed Stroop task, on speech kinematics and perioral muscle activation. Method: Acoustic, kinematic, and surface electromyographic data were collected from the verbal responses of 30 young adult healthy control…

The current study investigated the long-term effects of institutionalization on the inhibitory control of young adults raised in orphanages using the color-word Stroop task. We examined whether young adults raised in institutions (IC group; n = 24; M = 22.17 years, SD = 6.7) would demonstrate poorer behavioral performance and atypical neural…

Response control or inhibition is one of the cornerstones of modern cognitive psychology, featuring prominently in theories of executive functioning and impulsive behavior. However, repeated failures to observe correlations between commonly applied tasks have led some theorists to question whether common response conflict processes even exist. A…

According to the executive framework of prospective memory (PM), age-related differences in PM performance are mediated by age-related differences in executive functioning (EF). The present study further explored this framework by examining which specific components of EF are associated with PM differences between and within three age groups. A…

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…

In 2 variants of the color-word Stroop task, we compared 5 types of color-neutral distractors--real words (e.g., "HAT"), pseudowords (e.g., "HIX"), consonant strings (e.g., "HDK"), symbol strings (e.g., #$%), and a row of Xs (e.g., "XXX")--as well as incongruent color words (e.g., "GREEN" displayed…

Executive functioning deficits found in college students with ASD may have debilitating effects on their everyday activities. Although laboratory studies tend to report unimpaired inhibition in autism, studies of resistance to distractor inhibition reveal difficulties. In two studies, we compared a Virtual Classroom task with paper-and-pencil and…

Inhibition is often conceptualized as a unitary construct reflecting the ability to ignore and suppress irrelevant information. At the same time, it has been subdivided into inhibition of prepotent responses (i.e., the ability to stop dominant responses) and resistance to distracter interference (i.e., the ability to ignore distracting…

Event-based prospective memory (PM) is the ability to remember to perform an intention in response to an environmental cue. Recent microstructure models postulate four distinguishable stages of successful event-based PM fulfillment. That is, (a) the event must be noticed, (b) the intention must be retrieved, (c) the context must be verified, and…

Reading fluency is often predicted by rapid automatized naming (RAN) speed, which as the name implies, measures the automaticity with which familiar stimuli (e.g., letters) can be retrieved and named. Readers with dyslexia are considered to have less "automatized" access to lexical information, reflected in longer RAN times compared with…

Sequential relationships between Stroop color-word stimuli were explored in a random discrete-trials manual response design. Posttrial availability of an interfering response was indicated by a subsequent reduction of reaction time when that response became appropriate. Previous evidence for suppression of competing responses is probably…
