We investigated a possible source of contamination of expired-air carbon monoxide (CO) readings on CO monitors from raised expired-air hydrogen (H2) levels, namely lactose intolerance, the norm in certain ethnic groups. A significant correlation between expired-air CO and H2 readings was observed in four non-smoking lactose maldigesters.
The results of two experiments show that pictures, pattern masked to prevent conscious representation, could nevertheless influence the interpretation of supraliminally presented ambiguous pictures. This priming effect was obtained under conditions of dichoptic masking (Expt 1) and under conditions in which the picture primes were presented to one eye and the ambiguous pictures presented to the other eye (Expt 2). In obtaining priming under conditions of pattern masking, the results substantiate recent claims that pattern masking does not prevent perceptual processing. Instead, it appears to prevent the recovery of some of the products of perceptual processing necessary for conscious report. The findings are discussed within the framework of current models of picture processing.
