Diving Physiology<br />

Information recall from long term memory is dependent on the complexity (or detail)<br />

of the information content. Thus, while divers could recall most (85%) of the basic<br />

information observed at 40 msw after 2 hours, they were able to recall less than half<br />

(49%) of the detailed information such as alpha-numeric data. As different ordinance<br />

can have a similar designs of which there are several variations, the more detailed<br />

information collected by the diver may be crucial to proper identification.<br />

The absence of significant interactions between the three factors suggests that the<br />

effects of pressure, elapsed time and level of detail are additive in nature rather than<br />

synergistic. Results indicated that there was no significant interaction effect between<br />

pressure and the level of detail reported by the diver (for all time conditions). An<br />

interaction would not necessarily be expected since divers were exposed to the effects<br />

of narcosis only during the immediate recall condition. For immediate recall, there<br />

was a trend for more complex information to show a greater decrement at pressure<br />

(when narcosis was present). Hence, further investigation of the effect of narcosis on<br />

different levels of information detail is warranted. Although the interaction between<br />

elapsed time and level of detail was not significant at the p
