Article Abstract:
An additive factors method experiment shows that hypoxia produces an additive rather than an interactive effect on mental rotation and does not slow stimulus identification. The slowing produced by hypoxia is limited to a few early stages of visual processing only. The study proves that the multiple loci hypothesis is incorrect. The investigation involves eight highly trained individuals who perform mental rotation tasks, with blood oxygen saturation maintained at 64%.

Article Abstract:
The effect of training on comprehension and retention of safety pictorials was investigated. A set of safety pictorials was categorized as either easy or difficult to understand. A training procedure was then initiated to enhance comprehension and retention. Comprehension tests were given at numerous intervals to monitor training effectiveness. Brief training with an associated verbal label was found to increase comprehension of difficult pictorials.

Article Abstract:
A study exploring the effects of interference between switched tasks was conducted on 96 female psychology students. An experiment measured these effects using a time-sharing situation in the processing of two tasks. Results indicate that interruption of an initial task is deliterious to the processing time of the second and increases error rate. Ommisions, confusions and intrusions occured more frequently in the second task.
