“…A quick and efficient method of finding point thresholds is titration, introduced by Bkesy (1947) and Oldfield -(1949). Titration procedures have been used widely with animals since the pioneering work of Blough (1955Blough ( , 1958; see review by Rosenberger (1970). The procedure has been applied to preference in four connections: escape performance Laties, 1958, 1970; however, their results were connected with perception of pain rather than preference), punishment (Rachlin, 1972), intracranial self-stimulation (Stein and Ray, 1959), and determining the maximum cost of switching between two schedules (Verhave, 1963).…”

Pigeons were tested in a computer-controlled two-key chamber. A standard (nonchanging) schedule of reinforcement was in force on one key, and an adjusting schedule on the other. The schedules were available concurrently after each reinforcement, but after the first peck on either key (the choice peck), the schedule on the other key was made inoperative. The parameter of the adjusting schedule was decreased when the standard schedule was chosen and increased when the adjusting schedule was chosen. The standard schedule was changed only between sessions. Fixed intervals and fixed ratios were used as standard schedules, and intervals and ratios were used as adjusting schedules. When standard and adjusting schedules were of the same type, median parameters on the adjusting key equalled those of the standard schedules, at four values of each standard schedule. For four of five birds, and for the group median, similar curves could be plotted through the indifference points obtained from a standard ratio with an adjusting interval, and from a standard interval with an adjusting ratio. These points showed consistent individual differences, but they could be predicted by assuming that the median time from the choice peck to reinforcement should be the same on both keys. This is equivalent to treating the schedule as a concurrent chain and assuming that Herrnstein's quantitative law of effect applies.

“…Arrangements going under the name of adjusting, tracking, titration, or up-down schedules have proven useful in determining such psychophysical properties as absolute thresholds (Rosenberger, 1970;Stebbins, 1970;Bekesy, 1947) and points of subjective equality (Church, Getty, & Lerner, 1976). A psychophysical orientation leads to the view that the present titration procedure provided information about the DRO value serving as the indifference point between the DRO and RI schedules, where the indifference point is the mean DRO.…”

Responses and Pauses: Discrimination and a Choice Catastrophe

Pigeons produced a stimulus change either by responding or by not responding for a specified time period (by pausing). They then had to choose between two responses to obtain food. One choice was correct if the first component had been completed by a response; the other was correct if the component had been completed by a pause. The pigeons usually chose correctly, thereby indicating that they used their own prior behavior as a discriminative stimulus. Fixed pause requirements did not produce equal first component completions by a response and by a pause. To obtain equality, the pause requirement was titrated as a function of current performance. Titration resulted in equal completions and also produced accurate discrimination. In addition to showing that pigeons discriminated whether they had responded or paused, the data displayed and discontinuous functions predicted by catastrophe theory. Another procedure used forced choice rather than titration to produce equal completions by pausing and responding and also showed accurate discrimination of behavior.

“…A tracking procedure was used during rabbit testing (Martin, Lonsbury-Martin, & Kimm, 1980; Rosenberger, 1970). The 50% correct level was targeted in a one-up, one-down paradigm (Levitt, 1971) to study performance at the lowest possible tone level without extinguishing the CR.…”

Studies of binaural detection in the rabbit (Oryctolagus cuniculus) with Pavlovian conditioning.

A Pavlovian conditioned eyeblink response in rabbits (Oryctolagus cuniculus) was used to study psychoacoustical phenomena previously demonstrated in human listeners and other animals. This article contains the results of a tone-in-noise detection study to examine 2 psychoacoustical phenomena in rabbit and in human listeners: (a) the binaural masking level difference (BMLD) and (b) differential performance across reproducible noise masker waveforms. The rabbits demonstrated a BMLD comparable in size to other species. Significant differences in performance across reproducible noise masker waveforms were seen in the rabbits. This performance was compared with the performance of human listeners using the same set of waveforms.
