Attentional control as an ability to regulate information processing during goal-directed behavior is critical many theories of human cognition and thought predict a large range everyday behaviors. However, in recent years, failures reliably assess individual differences attentional have sparked debate concerning whether control, currently conceptualized assessed, can be regarded valid psychometric construct. In this consensus paper, we summarize the current from theoretical, methodological,...
Abstract How cognitive control is recruited and implemented has become a major focus of researchers in psychology neuroscience. Current theories posit that operates at the level general rules—for example, Stroop task, “attend to color stimulus.” Here we report behavioral evidence suggesting much more locally, operating specific stimuli appearing task block. In addition, neural many regions implicated on including anterior cingulate cortex dorsolateral prefrontal cortex, operate local level.
Recent work on cognitive control focuses the conflict-monitoring hypothesis, which posits that a performance monitoring mechanism recruits regions in dorsolateral prefrontal cortex to ensure goal-directed behavior is optimal. Critical this theory single explains large number of behavioral effects including sequential congruency effect (SCE) and error-related slowing (ERS) effect. This leads prediction size these should correlate across tasks. To end, we conducted three large-scale individual...
Behaviour that is assumed to be guided by strategy can, in fact, based on the implicit learning of regularities environment. We demonstrate this point context a Stroop experiment. It has been shown previously performance measure cognitive control varies as function relative proportions congruent and incongruent trials block. Here we provide evidence modulation largely implicit, rather than explicit, knowledge these proportions. This result important implications for our understanding control.
The prioritized encoding and retrieval of valuable information is an essential aspect human memory. We used electroencephalography (EEG) to determine which two hypothesized processes underlies the influence reward value on episodic One hypothesis that engages prefrontal executive control processes, so stimuli engage elaborative rehearsal strategy benefits A second acts through reward-related midbrain dopamine system modulate synaptic plasticity in hippocampal cortical efferents, thereby...
The Gratton effect, the observation that size of Stroop effect is smaller following an incongruent trial compared to a congruent trial, one pivotal in support conflict-monitoring hypothesis. Previous reports have demonstrated non-conflict components, such as feature binding, also contribute this effect. Critically, Schmidt and De Houwer (2011) report flanker task button-press suggesting there no conflict adaptation effect; it entirely caused by binding. current investigation attempts...
Socioeconomic status (SES) has been linked to differences in the degree which people are attuned others. Those who lower SES also tend be more interpersonally attuned. However, date, this work not demonstrated using neural measures. In present electroencephalogram study, we found evidence that was stronger Mu-suppression during action observation. This finding adds growing literature on factors affect and suggests mirror neuron system may influenced by one's social class.
Translation accounts have argued that the presence of a Stroop effect in context nonvocal untranslated response is caused by verbal mediation. In its simplest form, color-labeled buttons are translated into code interferes with color responses. On this logic, reverse task (identify word; ignore color), responses made via word-labeled should also be verbally mediated. Thus, no (RSE) seen. The authors tested mediation hypothesis 4 experiments. An RSE was observed across results Experiments 3...
In everyday life, mental fatigue can be detrimental across many domains including driving, learning, and working. Given the importance of understanding accounting for deleterious effects on behavior, a growing body literature has studied role motivational executive control processes in fatigue. typical laboratory paradigms, participants complete task that places demand these self-control are later given subsequent task. Generally speaking, decrements to performance taken as evidence initial...
Proportion compatible manipulations are often used to index strategic processes in selective attention tasks. Here, a subtle confound proportion is considered. Specifically, as the of trials increases, ratio complete repetitions and alternations partial increases on but decreases incompatible trials. This demonstrated lead an overestimation magnitude effect context both Stroop Simon task. Implications for previous research directions future using discussed.
Multiplexed deep neural networks (DNN) have engendered high-performance predictive models gaining popularity for decoding brain waves, extensively collected in the form of electroencephalogram (EEG) signals. In this paper, to best our knowledge, we introduce a first-ever DNN-based generalized approach estimate reaction time (RT) using periodogram representation single-trial EEG visual stimulus-response experiment with 48 participants. We designed Fully Connected Neural Network (FCNN) and...
Abstract. Recent work in attentional control has suggested that conflict effects measured across different tasks are not reliable and by extension unrelated. The lack of correlation between these is juxtaposition only to theoretical predictions a domain-general mechanism but also large body individual differences research used show evidence for an construct its relatedness other psychological constructs. In effort address this, we fit hierarchical models each task modeled trial-to-trial...
Purpose: The Parent–Enhanced Moved by Reading to Accelerate Comprehension in English (Parent EMBRACE) program offers a bilingual parent-training literacy intervention for Latino families. Within the context of shared book reading, application leverages both home language and technology increase parent question-asking during reading. Research goals were (a) examine potential Parent EMBRACE tutoring system at teaching parents quantity variety their (b) changes parents' reading attitudes or...
Abstract. A central feature of many formal accounts reading aloud, and Coltheart colleagues dual-route cascaded model in particular, is that activation across various modules cascaded. Evidence reviewed this assumption problematic a particular context, along with solution involves thresholding the output letter level to nonlexical routine. Consideration known effects repetition leads prediction three-way interaction between stimulus quality, repetition, lexicality which quality interact when...
The proportion congruency effect refers to the observation that magnitude of Stroop increases as congruent trials in a block increases. Contemporary work shows effects can be driven by both context and individual items, are referred context-specific (CSPC) item-specific (ISPC) effects, respectively. conflict-modulated Hebbian learning account posits these manifest from same mechanism, while parallel episodic processing model ISPC occur simple associative learning. Our prior showed neural...
Decisions to trust help form the basis of relationships and society yet little is known about their neurophysiology. We told participants they were playing a coin toss game with trustworthy an untrustworthy person measured neural activity EEG as decided whether those fictitious interaction partners. Target people ostensibly correctly reported outcome on 66% trials. Behaviorally, probability matched chose flips from each profile equally by end 100 Electrophysiologically, there reliable...
Empathy has been a key focus of social, developmental, and affective neuroscience for some time. However, research using neural measures to study empathy in response social victimization is sparse, particularly young children. In the present study, 58 children's (White, non-Hispanic; five nine years old) mu suppression was measured electroencephalogram methods (EEG) as they viewed video scenarios depicting injustices toward White Black We found evidence increased victimization; however,...
Proportion congruency effects are the observation that magnitude of Stroop effect increases as proportion congruent trials in a block increases. Contemporary work shows can be specific to particular context. For example, Simon task which items appearing above fixation mostly and below incongruent, is larger for at top. There disagreement whether these context-specific result from simple associative learning or, instead, type conflict-mediated learning. Here, we address this question an ERP...
