Using frequency tagging to quantify attentional deployment in a visual divided attention task.
Frequency tagging is an EEG method based on the quantification of the steady state visual evoked potential (SSVEP) elicited from stimuli which flicker with a distinctive frequency. Because the amplitude of the SSVEP is modulated by attention such that attended stimuli elicit higher SSVEP amplitudes than do ignored stimuli, the method has been used to investigate the neural mechanisms of spatial...
متن کاملMeasuring auditory selective attention using frequency tagging
Frequency tagging of sensory inputs (presenting stimuli that fluctuate periodically at rates to which the cortex can phase lock) has been used to study attentional modulation of neural responses to inputs in different sensory modalities. For visual inputs, the visual steady-state response (VSSR) at the frequency modulating an attended object is enhanced, while the VSSR to a distracting object i...
متن کاملFrequency discrimination vs frequency estimation: adult age differences and the effect of divided attention.
In this experiment we explored age differences in frequency judgment. Young and older adults studied words occurring from one to six times under divided or focused attention and then completed either a frequency discrimination or a frequency estimation test for these items. Divided attention led to poorer performance on both frequency judgment tests, suggesting that distraction during the encod...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Divided attention in music
Two models have been advanced to account for the apparent ease with which attention can be divided in music: a `̀ divided attention’ ’ model postulates that listeners effectively manage to follow two or more melodic lines played simultaneously. According to a `̀ ® gure-ground model,’’ the harmonic coherence of Western polyphonies allows a listener to focus on one melody while staying aware of the...
