William James described (surprisingly accurately) this cognitive
construct in the following quote, "It is the taking of possession by the mind, in clear and vivid form, of one out of what seem several simultaneous objects or trains of thought.It implies withdrawal from some things in order to deal effectively with others." a.

Which of the following is false regarding selective attention?
a. The parietal cortex contributes heavily to selective attention b. Selective attention can enhance responses of neurons in many brain areas c. Selective attention sharpens our sensory machinery d. Neurons in the frontal cortex and superior colliculus discharge more briskly when animals attend to a stimulus. e. Evidence suggests that selective attention has very limited effects on information processing and should not be studied in depth |

effects on information processing and should not be studied in depth |

Why does fMRI have poor temporal resolution compared to EEG?
a). fMRI has relatively low invasiveness and is thus slower in capturing scans. b). fMRI has a high risk of radiation exposure so one must use fmri at very low frequency pulses c). fMRI measures activation from all areas of the brain which makes it slower because it is recording more data. d). Changes in blood flow occur on a longer time scale than neuronal spiking and the former is measured by fMRI and the latter is measured by EEG. e). none of the above are reasons why f MRI has a slower temporal resolution than EEG. |
d). Changes in blood flow occur on a longer time scale than neuronal spiking and the former is measured by fMRI and the latter is measured by EEG.
