Sentence examples for omission response from inspiring English sources
However, when button presses only generated sounds on 50% of the trials, no omission response was elicited.
The omission response was indistinguishable from the ERP response elicited by the tones until up to 50 ms after the omission.
(1976) suggested that this omission response could in part reflect anticipatory events activated by an internal representation of the temporal rhythm of stimulus presentation.
The omission response should be an exact copy of the sensory prediction, and thus resemble an evoked sensory response to the predicted stimulus.
Congruent and incongruent trials and errors of commission (response within 3 seconds) and omission (response after 3 seconds) errors were modeled as separate regressors in first-level multiple regression analysis.
For both modalities, when a stimulus was omitted, they found a negative potential whose onset was virtually synchronous with the missing stimulus and peaked at around 275 (visual) or 230 (auditory) ms. The topography of the negative omission response was dependent on the modality, showing some sensory specificity.
They were able to record omission responses peaking at 100 ms from electrodes that were also responsive to tones.
If we consider that omission responses uncover the underlying predictions, this second level prediction would also be responsible for larger omission responses in the same time window in xxxxy blocks, as this prediction would only be present in these blocks, increasing the magnitude of prediction-related activity.
Three different manipulations of task uncertainty – reward omission, response-requirement uncertainty and active-lever location uncertainty – each resulted in increased observing behaviour, possibly as a result of reduced ability to discriminate active from inactive levers, when no external signals guided lever choice, and under conditions of increased uncertainty.
(2013a), the initial N1-like omission responses were followed by an N2 and a P3 response.
Therefore, if a sequence is interrupted early, clear omission responses can be found.
