Abstract in brief

This text discusses the concept of blindsight, where individuals can respond to visual stimuli without conscious awareness, often resulting from damage to the primary visual cortex (V1) or induced temporarily through transcranial Magnetic Stimulation (TMS).
It explains that some scientists believe that apparent unconscious visual responses might actually be due to measurement biases, especially when using yes-no response tasks, and that more accurate, bias-free measures like d (a psychophysical measure) are necessary to determine true unconscious vision.
The experiments described show that when proper measures are used, normal subjects under TMS do not exhibit genuine blindsight, implying that previous evidence of unconscious vision may be influenced by how responses are measured rather than actual unconscious perception.]

Understanding Blindsight: Unconscious Vision or Response Bias?

Blindsight involves responses to visual stimuli without conscious awareness, often from visual cortex damage or TMS. Proper measurement methods suggest that unconscious vision may be due to response biases rather than…
