A visual Simon task was used to study the influence of aging on visuospatial attention and inhibitory control processes. Responses were much slower for elderly than young participants. The delay in trials which stimulus response side did not correspond as compared when they (the effect) larger older people, even after correcting general slowing due aging. responses reflected a internal processing, indicated by progressively delays peak latencies N1, posterior contralateral negativity (PCN),...

Observers often miss the 2nd of 2 visual targets (first target [TI] and second [T2]) when these are presented closely in time; attentional blink (AB).The authors hypothesized that AB occurs because response to T2 is delayed by T1 processing, causing lose a competition for attention item follows it.The investigated this hypothesis determining whether attenuated precued.The results from 4 experiments showed duration magnitude were substantially reduced was observed improvement report did not...

In general, both consciously and unconsciously perceived stimuli facilitate responses to following similar stimuli.However, masked arrows delay arrows.This inverse priming has been ascribed inhibition of premature motor activation, more recently even special processing nonconsciously material.Here, depended on particular masks, was insensitive contextual requirements for increased inhibition, constant across response speeds.Putative signs in the electroencephalogram may as well reflect...

Briefly presented information, even if unidentifiable, may speed or delay required responses to following events. It has been assumed that this priming of the motor system occur without affecting attention and stimuli. In contrast notion, present study reports such unidentified stimuli have effects on a physiological indicator attentional system. A lateral posterior electroencephalogram component was evoked by laterally relevant shapes, reflecting shifts those shapes. This absent, however,...

Results of several neuroimaging studies support the functional equivalence model, which states that motor imagery (MI) and execution (ME) involve same processes, except for final component. In contrast, motor-cognitive model implies MI additionally involves frontal executive control processes. However, according to some authors may actually be more comparable preparation (MP). current electroencephalographic study, a version discrete sequence production paradigm was employed in human...

Abstract The influence of strategy was examined for a simple response task, choice-by-location and the Simon task by varying time pressure. Besides reaction (RT) accuracy, we measured force derived two measures from event-related EEG potential to form an index attentional orienting (posterior contralateral negativity: PCN) start motor activation (the lateralized readiness potential: LRP). For effects pressure were found on response-locked LRP, but not onset PCN stimulus-locked LRP. Thus,...

Viewing static photographs of objects in motion evokes higher fMRI activation the human medial temporal complex (MT+) than looking at similar without this implied motion. As MT+ is traditionally thought to be involved perception (and not form perception), finding suggests feedback from object-recognition areas onto MT+. To investigate hypothesis, we recorded extracranial potentials evoked by sight biological agents with and The difference potential between responses pictures was maximal 260...

Learning movement sequences is thought to develop from an initial controlled attentive phase a more automatic inattentive phase. Furthermore, execution of becomes faster with practice, which may result changes at general motor processing level rather than effector specific level. In the current study, we examined whether these are already present during preparation. Fixed series six keypresses, either familiar or unfamiliar, had be prepared and executed/withheld after go/nogo signal....

Research has shown that retrieval of learned information is better when the original learning context reinstated during testing than this changed. Recently, such contextual dependencies have also been found for perceptual-motor behavior. The current study investigated nature context-dependent in discrete sequence production task, and addition examined whether amount practice affects extent to which sequences are sensitive alterations. It was changing cues-but not removal cues-had a...

Motor imagery (MI) refers to the process of imagining execution a specific motor action without actually producing an overt movement. Two forms MI have been distinguished: visual and kinesthetic MI. To distinguish between these we employed event related potential (ERP) study measure interference effects induced by hand orientation manipulations in laterality judgement task. We hypothesized that this manipulation should only affect but not The ERPs elicited rotated stimuli contained classic...

Purpose The purpose of this paper is to assess whether or not electroencephalography (EEG) provides a valuable and substantial contribution the prediction consumer behaviour their preferences during product consumption. In study, authors especially focus on individual wine tasting experience. Design/methodology/approach A neuroscience experiment was carried out with 26 participants that evaluated different red wines while brain activity recorded EEG. within-subjects design employed in two...

Abstract The late part of the Contingent Negative Variation (CNV) is assumed to be a composite potential, reflecting both movement preparation and several other processes. To assess contribution hand-motor overall CNV, three S1-S2 experiments were performed. Replicating earlier results that have been interpreted as demonstrating preparation, experiment 1 showed CNV gets larger centro-parietally under speed instruction. Experiments 2 3 compared for hand responses (key-press) ocular (saccades)...
