Alcohol and elaborative schemas for sentences.

Three experiments were conducted to determine whether alcohol-induced impairments of memory would be reduced by providing subjects with elaborative schemas. Anomalous sentences were presented to sober or intoxicated subjects either alone or with context words to facilitate comprehension. Memory was tested immediately with a yes-no recognition task. The results consistently showed that context words did not increase the number of hits in either sober or intoxicated subjects, and sober subjects made reliably more hits whether or not context words had been provided. The accuracy of recognition of distractors, however, was consistently improved by the presentation of context words, and was much more improved for intoxicated than for sober subjects. The results indicate that alcohol intoxication disrupted the production of elaborative schemas for understanding, but that intoxicated subjects were quite successful at utilizing such schemas as long as the schemas had been provided for them.

Fact and fantasy: the roles of accuracy and variability in confusing imaginations with perceptual experiences.

In Experiment 1, pictures were presented to subjects two, five, or eight times, and subjects were asked to imagine each pciture two, five, or eight times. Subsequently, subjects estimated the number of times each picture had been presented. Their estimates of the frequency of these external events were influenced by imagination trials; this effect was greater for good imagers than for poor imagers. Experiment 2 involved a similar design in which subjects were asked either to imagine the same referent for a word or to imagine a different referent for a word on successive imagination trials. Consistency (same referent) did not increase the influence of imaginations on immediate judgments of external frequency. Thus, the results of Experiment 1 were attributed to the greater accuracy (as opposed to greater consistency) of good imagers' internal generations of the stimuli. Furthermore, variation (imagining different referents), like greater accuracy, increased the effects of imagination trials on immediate but not on delayed judgments of frequency. Possible mechanisms underlying these effects are discussed. In general, the two studies show that qualitative characteristics of completely covert generations influence their impact on estimates of the frequency of external events.

Cardio-respiratory changes during pneumoencephalography.

Carbon-respiratory changes associated with changes in posture and injection of intrathecal oxygen were studied in fifeen patients undergoing pneumoencephalography in a Phillips isocentric chair, while breathing spontaneously and anaesthetised with halothane in oxygen. Haemodynamic changes associated with changes in posture were of a minor nature. A rise in PaCO2 occurred in the prone position in two obese patients. There were significant rises in blood pressure following injection of more than 5 ml of oxygen as a bolus into the subarachnoid space.
