Abstract:

With respect to press duration, t, and interresponse time, i, rats under FR5 and VR5 schedules and subsequent extinction behaved similarly. During acquisition days, mean t and mean i decreased, and mean response rate increased. Compared with acquisition, in extinction a the relative frequency of short ts decreased, b either the relative frequency of short is decreased or the relative frequencies of both short and long is increased. Variations in several central tendency and variability measures of t and i within the first extinction day were greater than variations within the last acquisition day. Median duration of the first press or of the first interresponse time following water-dipper operation was relatively long postreinforcement pause. Thereafter, both median t and median i, as function of ordinal number following dipper operation, tended to remain relatively constant. Within an FR5 or VR5 cycle, response rate changed abruptly from zero to a constant rate. During extinction, periods of responding at a normal or slightly subnormal rate alternated with periods of little or no responding. Author
