The effects of selective attention on chromatic processing; pattern-onset VEP responses
… visual areas show robust effects with attentional modulations. Recording from lower visual areas such as V1 has not shown consistent attentional effects. Chromatic pattern-onset VEPs are thought to be low-level visual responses recorded over the primary occipital area. They have not …

Pattern Reversal Chromatic VEPs like Onsets, are unaffected by Attentional Demand
… the chromatic onset VEP appears to be robust to attentional shifts. Functional magnetic resonance imaging (fMRI) responses to both chromatic and achromatic reversing patterns are also affected by attention. Resolution and comparison of these results is problematic due to differences in …

Learned Attention in Younger and Older Adults
… experiment suggest that older adults can learn attentional shifts in order to guide associative learning and reduce errors in causal judgments. These data prove to be a problem for many models of associative learning (e.g., Mackintosh, 1975; Rescorla & Wagner, 1972; Van Hamme & Wasserman, 1994), …

Follow the signal: models of attention, reason, and belief
… and linguistic signals that reflect aspects of attentional shifts, expressions of reasoning, and evolving belief states, and investigate how machine learning can be used to detect and interpret them as they arise in everyday settings. First, I focus on moments of inward attention, identifying …

Stress and selective attention : the impact of a stressful challenge on mood, cortisol, and the processing of emotional information
… an aversive stressful experience, and that the attentional response to stress would mediate mood and HPA reactivity. Stress induction was achieved by means of a competitive Stroop task with monetary rewards where participants either repeatedly lost (negative stressor) or won (positive stressor) …

Chronic Stress Effects on Prefrontal Cortical Structure and Function
… for this observation remain poorly understood. Attentional impairments symptomatic of depression are associated with structural and functional abnormalities in the prefrontal cortex. In three parallel rodent and human neuroimaging studies, this project assessed the effects of chronic stress on …

Interactions between numbers and space : neurobehavioural evidence from children and adults
… may be driven by a network subserving attentional shifts and saccadic eye movements, which might also be involved in calculation. Numerical cognition and calculation might therefore be conceived as operations on a mental number line akin to physical movements along a physical …

Age-related differences in visuomotor integration as measured by object affordance effects - a combined behavioural and neurophysiological investigation
… hypothesis (according to which attentional shifts are responsible for the generation of automatic response codes, rather than the affects arising from afforded actions), by using a novel stimulus set in which such attentional differences can be ruled out. Results provided strong …

Der Zusammenhang von objektivem und subjektivem Blickort als Indikator für die visuelle Aufmerksamkeitsausrichtung
Normalerweise stimmen die Ausrichtung der Augen und die der visuellen Aufmerksamkeit überein. Frühere Arbeiten, vor allem im Kontext so genannter ‚Fixieren-Springen’ Paradigmen, haben gezeigt, dass zum Zeitpunkt der Programmierung einer neuen Sakkade die Aufmerksamkeit bereits zum Sakkadenziel …
