Auditory attention to frequency and time: an analogy to visual local-global stimuli.
Two priming experiments demonstrated exogenous attentional persistence to the fundamental auditory dimensions of frequency (Experiment 1) and time (Experiment 2). In a divided-attention task, participants responded to an independent dimension, the identification of three-tone sequence patterns, for both prime and probe stimuli. The stimuli were specifically designed to parallel the local-global...
متن کاملAn fMRI study of human visual cortex in response to spatiotemporal properties of visual stimuli
ABSTRACT Background: The brain response to temporal frequencies (TF) has been already reported, but with no study reported for different TF with respect to various spatial frequencies (SF). Materials and Methods: fMRI was performed by 1.5T GE-system in 14 volunteers during checkerboard, with TFs of 4, 6, 8 and 10Hz in low and high SFs of 0.5 and 8cpd. Results: Average percentage BOLD signa...
متن کاملAttention to motion enhances processing of both visual and auditory stimuli: an event-related potential study.
The present event-related potential (ERP) study investigated whether attending to a particular direction of motion similarly enhances the processing of auditory and visual stimuli. ERPs were recorded while participants perceived horizontally moving visual and auditory stimuli. Attention was manipulated by asking participants to detect an infrequent target stimulus that was of a specified modali...
متن کاملVisual and auditory cues to attention : The effect of visual attentional focus on frequency selectivity
An experiment was carried out to determine whether visual cues to attention could affect frequency selectivity. The 19 participants each completed baseline thresholds for auditory and visual stimulus discrimination. Visual thresholds were defined by contrast while auditory thresholds were defined by sound to noise ratio. Participants then had their accuracy tested in both auditory and visual di...
متن کاملModification of sudden onset auditory ERP by involuntary attention to visual stimuli.
To investigate the cross-modal nature of the exogenous attention system, we studied how involuntary attention in the visual modality affects ERPs elicited by sudden onset of events in the auditory modality. Relatively loud auditory white noise bursts were presented to subjects with random and long inter-trial intervals. The noise bursts were either presented alone, or paired with a visual stimu...
