Brain‐Mind And Structure‐Function Relationships: A Methodological Response To Coltheart, Adina L. Roskies
Brain‐Mind And Structure‐Function Relationships: A Methodological Response To Coltheart, Adina L. Roskies
Dartmouth Scholarship
In some recent papers, Max Coltheart has questioned the ability of neuroimaging techniques to tell us anything interesting about the mind and has thrown down the gauntlet before neuroimagers, challenging them to prove he is mistaken. Here I analyze Coltheart’s challenge, show that as posed its terms are unfair, and reconstruct it so that it is addressable. I argue that, so modified, Coltheart’s challenge is able to be met and indeed has been met. In an effort to delineate the extent of neuroimaging’s ability to address Coltheart’s concerns, I explore how different brain structure‐function relationships would constrain the ability of …
Microsaccade Rate Varies With Subjective Visibility During Motion-Induced Blindness, Po-Jang Hsieh, Peter U. Tse
Microsaccade Rate Varies With Subjective Visibility During Motion-Induced Blindness, Po-Jang Hsieh, Peter U. Tse
Dartmouth Scholarship
Motion-induced blindness (MIB) occurs when a dot embedded in a motion field subjectively vanishes. Here we report the first psychophysical data concerning effects of microsaccade/eyeblink rate upon perceptual switches during MIB. We find that the rate of microsaccades/eyeblink rises before and after perceptual transitions from not seeing to seeing the dot, and decreases before perceptual transitions from seeing it to not seeing it. In addition, event-related fMRI data reveal that, when a dot subjectively reappears during MIB, the blood oxygen-level dependent (BOLD) signal increases in V1v and V2v and decreases in contralateral hMT+. These BOLD signal changes observed upon perceptual …
Memory And Musical Expectation For Tones In Cultural Context, Meagan E. Curtis, Jamshed J. Bharucha
Memory And Musical Expectation For Tones In Cultural Context, Meagan E. Curtis, Jamshed J. Bharucha
Dartmouth Scholarship
WE EXPLORED HOW MUSICAL CULTURE SHAPES ONE'S listening experience.Western participants heard a series of tones drawn from either the Western major mode (culturally familiar) or the Indian thaat Bhairav (culturally unfamiliar) and then heard a test tone. They made a speeded judgment about whether the test tone was present in the prior series of tones. Interactions between mode (Western or Indian) and test tone type (congruous or incongruous) reflect the utilization of Western modal knowledge to make judgments about the test tones. False alarm rates were higher for test tones congruent with the major mode than for test tones congruent …
