Within-subject reliability, occasion specificity, and validity of fluctuations of the Stroop and Go/No-Go tasks in ecological momentary assessment

Published: Sept. 18, 2023

Following the (revised) latent state-trait theory present study investigates within-subject reliability, occasion specificity, common consistency, and construct validity of cognitive control measures in an intensive longitudinal design. These indices were calculated applying dynamic structural equation modelling while accounting for autoregressive effects trait change. In two studies, participants completed tasks (Stroop Go/No-Go) answered questions about goal-pursuit, self-control, executive functions, situational aspects, multiple times per day. The sample (aged 18–30 years both studies) consisted 21 (14 females) Pilot Study 70 (48 female) Main Study. Findings indicate poor reliability Stroop task error rate reaction time difference between congruent incongruent trials moderate to good Go/No-Go time. Occasion specificity – systematic variance accounted by state residuals was on a modest level (between 1.4% 11.1%) difference, 16.1% 37.2% time) studies. Common consistency variables high all investigated scores. Indicative validity, rates correlated positively with each other within- between-subject level. Within-subject correlations scores subjective self-control very small mostly not significant.

On the (un)reliability of common behavioral and electrophysiological measures from the stop signal task: Measures of inhibition lack stability over time.

Published: Sept. 24, 2023

Response inhibition, the intentional stopping of planned or initiated actions, is often considered a key facet control, impulsivity, and self-regulation. The stop signal task argued to be purest inhibition we have, it thus central much work investigating role in areas like development psychopathology. Most this quantifies behavior by calculating reaction time as measure individual latency. Individual difference studies aiming investigate why how latencies differ between people do under assumption that indexes stable, dispositional trait. However, empirical support for lacking, common measures control tend show low test-retest reliability appear unstable over time. reasons could methodological, where stability driven measurement noise, substantive, larger influence state-like situational factors. To this, characterized split-half range behavioral electrophysiological derived from task. Across three independent studies, different modalities, systematic review literature, found pattern temporal higher manifest non-inhibitory processing. This not explained noise internal consistency. Consequently, response appears have mostly determinants, there little validity conceptualizing reflecting stable traits.
