Abstract:

The effect of presentation rate on a mans ability to determine which of two mutually exclusive random sequential events has occurred more frequently was investigated using rates of one, two, four and eight events per second. Two specific studies were carried out using the same relative differential frequencies between the events but varying the absolute number of events in the total series. The results indicate that the accuracy of perceiving the more frequent event decreases as the presentation rate of the events increases. The effect of rate also acted differently for a short and long series of events as presentation rate increased, a short series of events showed a significantly steeper decline in accuracy than a long series of events.
