Direct injection of noise to the visual cortex decreases accuracy but increases decision confidence.
The relationship between accuracy and confidence in psychophysical tasks traditionally has been assumed to be mainly positive, i.e., the two typically increase or decrease together. However, recent studies have reported examples of exceptions, where confidence and accuracy dissociate from each other. Explanations for such dissociations often involve dual-channel models, in which a cortical chan...

متن کاملNoise and Equivalent Circuit of Double Injection
.Measurements o~ the high-frequ~ncy noi:e of a silicon double-injection diode result in (i'l)=a• 4kT ( 1/r) ~if With a= 1.04 and m agreement With the literature. A new interpretation demands Nyquist noise with a 121 in these devices at high frequencies. This is in accord with an equivalent circuit derived for the doubleinjection process. Speculations are made on the general validity of Nyquist ...
متن کاملNot so fast: the (not-quite-complete) dissociation between accuracy and confidence in thin-slice impressions.
After decades of research highlighting the fallibility of first impressions, recent years have featured reports of valid impressions based on surprisingly limited information, such as photos and short videos.Yet beneath mean levels of accuracy lies tremendous variance-some snap judgments are well-founded, others wrongheaded. An essential question for perceivers, therefore, is whether and when t...
متن کاملDissociation Between Memory Accuracy and Memory Confidence Following Bilateral Parietal Lesions
Numerous functional neuroimaging studies have observed lateral parietal lobe activation during memory tasks: a surprise to clinicians who have traditionally associated the parietal lobe with spatial attention rather than memory. Recent neuropsychological studies examining episodic recollection after parietal lobe lesions have reported differing results. Performance was preserved in unilateral l...
