The event rate context in vigilance: Relation to signal probability and expectancy
Abstract The influence of the conditional probability of signals encountered during an adapting phase of a visual vigilance task on postadaptation performance was examined within the context of different background event rates (frequencies of presentation of repetitive neutral events).

| 520 | |a Abstract The influence of the conditional probability of signals encountered during an adapting phase of a visual vigilance task on postadaptation performance was examined within the context of different background event rates (frequencies of presentation of repetitive neutral events). Slow (6 events/min) and fast (30 events/min) event rates were used. Within each event rate, four groups of subjects experienced either a low (.025) or a high (.125) conditional probability of signals for 20 min (adaptation phase) and then experienced either the same or the alternate probability for an additional 40 min (postadaptation phase). The overall frequency of correct detections was inversely related to event rate. With the fast event rate, subjects who were initially exposed to a high signal probability detected more signals during the post-adaptation phase than those who received early exposure to a low signal probability. By contrast, the effects of signal probability were negligible within the context of a slow event rate. These results suggest some limits to the applicability of an expectancy theory of vigilance. | ||

The event rate context in vigilance: Relation to signal probability and expectancy |
| abstract |
Abstract The influence of the conditional probability of signals encountered during an adapting phase of a visual vigilance task on postadaptation performance was examined within the context of different background event rates (frequencies of presentation of repetitive neutral events). Slow (6 events/min) and fast (30 events/min) event rates were used. Within each event rate, four groups of subjects experienced either a low (.025) or a high (.125) conditional probability of signals for 20 min (adaptation phase) and then experienced either the same or the alternate probability for an additional 40 min (postadaptation phase). The overall frequency of correct detections was inversely related to event rate. With the fast event rate, subjects who were initially exposed to a high signal probability detected more signals during the post-adaptation phase than those who received early exposure to a low signal probability. By contrast, the effects of signal probability were negligible within the context of a slow event rate. These results suggest some limits to the applicability of an expectancy theory of vigilance. © The Psychonomic Society, Inc. 1977 |

Abstract The influence of the conditional probability of signals encountered during an adapting phase of a visual vigilance task on postadaptation performance was examined within the context of different background event rates (frequencies of presentation of repetitive neutral events). Slow (6 events/min) and fast (30 events/min) event rates were used. Within each event rate, four groups of subjects experienced either a low (.025) or a high (.125) conditional probability of signals for 20 min (adaptation phase) and then experienced either the same or the alternate probability for an additional 40 min (postadaptation phase). The overall frequency of correct detections was inversely related to event rate. With the fast event rate, subjects who were initially exposed to a high signal probability detected more signals during the post-adaptation phase than those who received early exposure to a low signal probability. By contrast, the effects of signal probability were negligible within the context of a slow event rate. These results suggest some limits to the applicability of an expectancy theory of vigilance. © The Psychonomic Society, Inc. 1977 |
