Abstract

During binocular rivalry, visual perception switches between a stimulus viewed by one eye and a different stimulus viewed by the other. We studied rivalry in split-brain observers to test two explanations. Rivalry could reflect switching of activity between the cerebral hemispheres, or switching by a structure in the right frontoparietal cortex. From these two theories, we predict no rivalry when stimuli are presented to a split-brain observer's left hemisphere. Yet we found similar rivalry from the left and right hemispheres of the split-brain observers, consistent with switchings being mediated by low-level processes within each hemisphere.

The timing of brain events: reply to the "Special Section" in this journal of September 2004, edited by Susan Pockett.

In this "Reply" paper, the arguments and experimental findings by Pockett, Pollen, and Haggard et al. are analyzed. It had been shown () that a 0.5s duration of repetitive activations of sensory cortex is required to produce a threshold of sensation. The view that this is due to a facilitatory buildup in excitatory state to finally elicit neuronal firing is shown to be incompatible with several lines of evidence. Objections to the phenomenon of subjective referral backwards in time (for the delayed sensation) are also untenable. report that a self-initiated act can, under hypnotic suggestion, appear to the subject to be "involuntary." The act under hypnosis is better viewed as one initiated unconsciously, not as an act of conscious will.

Nonconscious semantic processing of emotional words modulates conscious access.

Whether masked words can be processed at a semantic level remains a controversial issue in cognitive psychology. Although recent behavioral studies have demonstrated masked semantic priming for number words, attempts to generalize this finding to other categories of words have failed. Here, as an alternative to subliminal priming, we introduce a sensitive behavioral method to detect nonconscious semantic processing of words. The logic of this method consists of presenting words close to the threshold for conscious perception and examining whether their semantic content modulates performance in objective and subjective tasks. Our results disclose two independent sources of modulation of the threshold for access to consciousness. First, prior conscious perception of words increases the detection rate of the same words when they are subsequently presented with stronger masking. Second, the threshold for conscious access is lower for emotional words than for neutral ones, even for words that have not been previously consciously perceived, thus implying that written words can receive nonconscious semantic processing.

A review of the literature on orientation as an indicator of level of consciousness.

PURPOSE: To review and compare the concepts of orientation and level of consciousness. METHODS: Literature review, including studies of orientation as an indicator of level of consciousness, in the domains of nursing, medicine, and neuropsychology. FINDINGS: Orientation to time, place, and person as a measure of level of consciousness is poorly understood. The nursing practice of assessing orientation is common in many practice settings, yet little research has been done to validate whether it is meaningful. CONCLUSIONS: This review lays important groundwork for future evidence-based research into the use of orientation as an indicator of level of consciousness.
