Attention for Speaking: Prestimulus Motor-cortical Alpha Power Predicts Picture Naming Latencies
There is a range of variability in the speed with which a single speaker will produce the same word from one instance to another. Individual differences studies have shown that the speed of production and the ability to maintain attention are related. ...
Frequency-based Dissociation of Symbolic and Nonsymbolic Numerical Processing during Numerical Comparison
Recent evidence suggests that during numerical calculation, symbolic and nonsymbolic processing are functionally distinct operations. Nevertheless, both roughly recruit the same brain areas (spatially overlapping networks in the parietal cortex) and ...
Neural Signatures of Learning Novel Object–Scene Associations
Objects are perceived within rich visual contexts, and statistical associations may be exploited to facilitate their rapid recognition. Recent work using natural scene–object associations suggests that scenes can prime the visual form of associated ...
Effects of Dopaminergic Drugs on Cognitive Control Processes Vary by Genotype
Dopamine (DA) has been implicated in modulating multiple cognitive control processes, including the robust maintenance of task sets and memoranda in the face of distractors (cognitive stability) and, conversely, the ability to switch task sets or update ...
Tracking Syntactic Conflict between Languages over the Course of L2 Acquisition: A Cross-sectional Event-related Potential Study
One challenge of learning a foreign language (L2) in adulthood is the mastery of syntactic structures that are implemented differently in L2 and one's native language (L1). Here, we asked how L2 speakers learn to process syntactic constructions that are ...
Large-scale Functional Integration, Rather than Functional Dissociation along Dorsal and Ventral Streams, Underlies Visual Perception and Action
Visual dual-stream theory posits that two distinct neural pathways of specific functional significance originate from primary visual areas and reach the inferior temporal (ventral) and posterior parietal areas (dorsal). However, there are several ...
Anodal High-definition Transcranial Direct Current Stimulation over the Posterior Parietal Cortex Modulates Approximate Mental Arithmetic
The representation and processing of numerosity is a crucial cognitive capacity. Converging evidence points to the posterior parietal cortex (PPC) as primary “number” region. However, the exact role of the left and right PPC for different types of ...
Tracking the Effects of Top–Down Attention on Word Discrimination Using Frequency-tagged Neuromagnetic Responses

Discrimination of words from nonspeech sounds is essential in communication. Still, how selective attention can influence this early step of speech processing remains elusive. To answer that question, brain activity was recorded with ...
Search for Face Identity or Expression: Set Size Effects in Developmental Prosopagnosia

The set size effect during visual search indexes the effects of processing load and thus the efficiency of perceptual mechanisms. Our goal was to investigate whether individuals with developmental prosopagnosia show increased set size effects when ...
Valence-dependent Disruption in Processing of Facial Expressions of Emotion in Early Visual Cortex—A Transcranial Magnetic Stimulation Study
Our visual inputs are often entangled with affective meanings in natural vision, implying the existence of extensive interaction between visual and emotional processing. However, little is known about the neural mechanism underlying such interaction. This ...
The Neural Consequences of Attentional Prioritization of Internal Representations in Visual Working Memory
Although humans can hold multiple items in mind simultaneously, the contents of working memory (WM) can be selectively prioritized to guide future behavior. We explored whether the “same-object” benefits in visual processing may also be observed in visual ...
Unraveling the Relation between EEG Correlates of Attentional Orienting and Sound Localization Performance: A Diffusion Model Approach

Understanding the contribution of cognitive processes and their underlying neurophysiological signals to behavioral phenomena has been a key objective in recent neuroscience research. Using a diffusion model framework, we investigated to what extent well-...
Affective Bias without Hemispheric Competition: Evidence for Independent Processing Resources in Each Cortical Hemisphere
We assessed the extent of neural competition for attentional processing resources in early visual cortex between foveally presented task stimuli and peripheral emotional distracter images. Task-relevant and distracting stimuli were shown in rapid serial ...
Neural Control of Emotional Actions in Response to Affective Vocalizations
Social–emotional cues, such as affective vocalizations and emotional faces, automatically elicit emotional action tendencies. Adaptive social–emotional behavior depends on the ability to control these automatic action tendencies. It remains unknown ...
Neural Mechanisms of Strategic Adaptation in Attentional Flexibility
Individuals are able to adjust their readiness to shift spatial attention, referred to as “attentional flexibility,” according to the changing demands of the environment, but the neural mechanisms underlying learned adjustments in flexibility are unknown. ...
