Most theories of attention propose that we maintain attentional templates in visual working memory to control what information is selected. In the present study, directly tested this proposal by measuring contralateral-delay activity (CDA) human event-related potentials during search tasks which target cued on each trial. Here show CDA can be used measure maintenance while processing complex scenes. addition, method allowed us observe shift from long-term representations controlling as...
Theories of attention are compatible with the idea that we can bias to avoid selecting objects have known nontarget features. Although this may underlie several existing phenomena, explicit guidance away from nontargets has yet be demonstrated. Here show observers use feature cues (i.e., color) items during visual search. These negative were used quickly instantiate a template for rejection reliably facilitated search across cue-to-search stimulus onset asynchronies (SOAs), although not as...
Theories of visual attention suggest that working memory representations automatically guide toward memory-matching objects. Some empirical tests this prediction have produced results consistent with guiding attention. However, others shown individuals can strategically control whether Previous studies not independently measured automatic and strategic contributions to the interactions between In study, we used a classic manipulation probability valid, neutral, invalid cues tease apart...
Our sensory environments contain more information than we can process, and successful behaviors require the ability to separate task-relevant from task-irrelevant information. Much research on attention has focused mechanisms that result in selection of desired information, but much less is known about how distracting ignored. Here, describe evidence strategic, learned, passive all contribute better distractor ignoring. The suggests there are multiple ways which ignoring supported, these may...
Biased competition theory proposes that representations in working memory drive visual attention to select similar inputs. However, behavioral tests of this hypothesis have led mixed results. These inconsistent findings could be due the inability measures reliably detect early, automatic effects on attentional deployment exert. Alternatively, executive mechanisms may govern how influence based higher-level goals. In present study, we tested these hypotheses using N2pc component participants'...
Recent behavioural research has provided support for an active attentional suppression of known distractor items. Reaction times are faster when participants informed the colour distractors composing half a search array than being with no information about (Arita, J. T., Carlisle, N. B., & Woodman, G. F. (2012).

Importance Understanding the heterogeneity of neuropsychiatric symptoms (NPSs) and associated brain abnormalities is essential for effective management treatment dementia. Objective To identify dementia subtypes with distinct functional connectivity subsyndromes. Design, Setting, Participants Using data from Open Access Series Imaging Studies-3 (OASIS-3; recruitment began in 2005) Alzheimer Disease Neuroimaging Initiative (ADNI; 2004) databases, this cross-sectional study analyzed...
Foreknowledge of target features biases attention toward those even before search begins, indicating proactive activation the template. However, whether foreknowledge distractor leads to inhibition remains debated, raising questions about and templates operate through similar mechanisms. The current study investigated this by presenting multiple task-irrelevant singleton probes display onset, combined with EEG. either matched color target, or had a neutral color. If feature-specific template...
Abstract Major depressive disorder (MDD) presents a substantial health burden with low treatment response rates. Predicting antidepressant efficacy is challenging due to MDD’s complex and varied neuropathology. Identifying biomarkers for requires thorough analysis of clinical trial data. Multimodal neuroimaging, combined advanced data-driven methods, can enhance our understanding the neurobiological processes influencing outcomes. To address this, we analyzed resting-state fMRI EEG...
Hypothesis-driven research rests on clearly articulated scientific theories. The building blocks for communicating these theories are terms. Obviously, communication – and thus, progress is hampered if the meaning of terms varies idiosyncratically across (sub)fields even individual researchers within same subfield. We have formed an international group experts representing various theoretical stances with goal to homogenize use that most relevant field visual distraction in search. Our...
Medication and other therapies for psychiatric disorders show unsatisfying efficacy, in part due to the significant clinical/ biological heterogeneity within each disorder our over-reliance on categorical clinical diagnoses. Alternatively, dimensional transdiagnostic studies have provided a promising pathway toward realizing personalized medicine improved treatment outcomes. One factor that may influence response treatments is cognitive function, which reflected one's intellectual capacity....
People can quickly learn spatial distributions of targets and direct attention to likely regions targets. These implicitly learned biases have been shown be persistent, transferring other similar visual search tasks. However, a persistent attentional bias is incompatible with frequently changing goals in our typical daily environment. We propose flexible goal-specific probability cueing mechanism address this discrepancy. examined whether participants could utilize target-specific priority...
Negative templates are based on foreknowledge of distractor features and can lead to more efficient visual search at the group level. However, large individual differences exist in size benefits induced by negative cues. The cognitive factors underlying these interindividual remain unknown. Previous research has suggested higher engagement proactive control for compared positive templates. We thus hypothesized that efficiency may explain variability cue benefits. A data set made up from two...
The question whether target selection in visual search can be effectively controlled by simultaneous attentional templates for multiple features is still under dispute. We investigated multiple-color guidance possible when colors remain constant and thus represented long-term memory but not they change frequently have to held working memory. Participants searched one, two, or three that were specified cue displays at the start of each trial. In constant-color blocks, same remained...
