“…The frontal enhancement in the hemispheric regions signifies the increased attention required for the centrally positioned stimuli. Corresponding with Doallo et al's (2005) findings, it is postulated that this central cueing was validated at an expected target's presentation, evoking the larger response to this imperative. However, as these topographic effects have not been reported previously, it is difficult to relate these findings to previous studies, particularly as a second N1 component was identified.…”

Clarifying the sequential processes involved in a cued continuous performance test

We aimed to clarify sequential processes for cue and imperative stimuli (targets/nontargets) in a continuous performance test (CPT), and how the preparatory contingent negative variation (CNV) affects physiological and behavioral responses. Single-trial event-related potentials (ERPs) obtained from 70 participants during a cued CPT were baselined to the cue (BtC) to include the CNV, or to the imperatives (BtI) to remove the CNV. Principal components analysis obtained cue and imperative ERP components, and congruence coefficients (rc ) evaluated similarities. The cue and imperative components were comparable, more so for the BtI- than BtC-imperative components (rc = .85). N1, PN, P2, N2c, and SW components were similar, but not the N2b and P3s. Imperative ERPs were largely unaffected by the resolving CNV. Similar cue and imperative components suggest similar sequential processes, while preparatory CNV activity enhanced physiological and behavioral responses.

“…Similar to previous studies (Mangun and Hillyard, 1991;Hopfinger and Ries, 2005), we found evidence for early sensory processing for validly cued compared with invalidly cued locations (indicated by a larger P1 component on valid trials). However, this difference was largely unaffected by cue predictability (Doallo et al, 2005). This dissociation between higher frequency responses in the gammaband range and the low-frequency responses in ERPs suggest that high-and low-frequency EEG activity reflect different neural mechanisms.…”

“…Voluntary and involuntary attention effects have seldom been directly compared under equal stimulus conditions within the same ERP study. Studies that attempted this comparison revealed no marked differences in the amplitudes of either P1 or N1 (Doallo et al, 2005).…”

Previous studies have shown that EEG activity in the gamma range can be modulated by attention. Here, we compared this activity for voluntary and involuntary spatial attention in a spatial-cueing paradigm with faces as targets. The stimuli and trial timing were kept constant across attention conditions with only the predictive value of the cue changing. Gamma-band response was linked to voluntary shifts of attention, but not to the involuntary capture of attention. The presence of increased gamma responses for the voluntary allocation of attention, and its absence in cases of involuntary capture suggests that the neural mechanisms governing these two types of attention are different. Moreover, these data allow a description of the temporal dynamics contributing to the dissociation between voluntary and involuntary attention. The distribution of this correlate of voluntary attention is consistent with a top-down process involving contralateral anterior and posterior regions.

“…Behavioral studies show that stimuli presented at the cued location (valid trials) are detected and discriminated faster and more accurate than that stimuli appearing at unprecued locations (invalid trials). These attentional effects occur in absence of eye movements (covert orienting of attention) (Jonides 1981;Müller and Rabbitt 1989;Posner 1980;Posner, Nissen and Ogden 1978;Doallo, Lorenzo-Lopez, Vizoso, Holguin, Amenedo, Bara and Cadaveira 2005).…”

EEG reveals brain electrical activities with high temporal resolution. Yet, multiple implicit variables may be involved in limited event related potential (ERP) measures. Special computation techniques are needed to recover these parameters. In the study of involuntary visual spatial attention, we may obtain the ERP in valid cued (V), invalid cued (I) and neutral cued (N) conditions. Usually, the effect of involuntary attention is computed by the subtraction model with the assumption that V/I and N are independent. Yet, they should be related. Treating V/I as a function of N, a linear model V(I) = W + GN is assumed, where W and G are implicit in the ERP measures. G is the gain control on the neutral function. Provided G and W are constant over a local brain region, we may use the Total Least Square (TLS) algorithm to compute their values. The values of W and G computed from an involuntary attention experiment data show that multiple implicit variables are involved in obtained ERPs. Here G acts as a "top-down" sensory modulator on the neutral ERPs and W is related to possible newly involved neural activities. The parameters derived from the new linear model also suggest that there are different mechanisms involved in involuntary attention and voluntary allocation of attention.
