“…The rates, patterns, and stability of responding maintained in the present experiment under the FI schedule are comparable to those obtained in previous experiments in which Fl schedules of electric shock presentation were introduced following prior exposure to schedules of food presentation (Kelleher and Morse, 1968), shock avoidance (e.g., Kelleher and Morse, 1969;McKearney, 1968McKearney, , 1969Malagodi et al, 1973), or escape from shock (Mc-Kearney, 1974a). Similarly, the characteristics of responding maintained under the FT schedule in the present experiment are comparable to those previously obtained in experiments in which FT sclhedules of electric shock presentation were introduced following a history of escape from shock (McKearney, 1974a) or introduced with no prior experimental history (Hutchinson, 1977;Hutchinson and Emley, 1972;Hutchinson et al, 1971).…”

“…Morse, 1966;Morse andKelleher, 1970, 1977;Zeiler, 1977). Additional support for this view may be found in the results of previous experiments with response-dependent schedules of electric shock presentation which have shown: (a) characteristic rates and patterns of responding under VI (McKearney, 1972a(McKearney, , 1974bMalagodi et al, 1973), concurrent VI VI (Malagodi et al, 1973), multiple fixedinterval fixed-ratio (McKearney, 1970), and second-order (Byrd, 1972) schedules of electric shock presentation; (b) an inverse relationship between response rate and parameter value of Fl schedules (McKearney, 1969;Malagodi et al, 1973); (c) a decrease in response rate following introduction of a brief delay between the effective response and shock presentation (Byrd, 1972); and (d) cessation of responding under extinction with subsequent recovery of performance following reintroduction of the Fl schedule (Kelleher and Morse, 1968;Mc-Kearney, 1969).…”

“…In the present experiment, Monkeys SM-43 and SM-44 had been exposed to 45 and 59 sessions, respectively, under Fl 6-min before being exposed to the multiple schedule. They had also served in a previous experiment during which responding had been maintained for several hundred sessions under Fl shedules of electric shock presentation (Malagodi et al, 1973). It is also possible that induction (e.g., Reynolds, 1961) between components prevented the emergence of differential response rates.…”

“…Three adult male squirrel monkeys (Saimiri sciurea) served. Two monkeys (SM-43 and SM-44) had previous histories under schedules of shock postponement and shock presentation (Malagodi et al, 1973). The third monkey, SM-37, was experimentally naive.…”

“…Within the past decade, a number of experiments have demonstrated the maintenance of lever pressing under conditions in which presentation of noxious electric shock is intermittently scheduled as the only consequence of responding (Byrd, 1969(Byrd, , 1972Morse, 1968, 1969;McKearney, 1968McKearney, , 1969McKearney, , 1970McKearney, , 1972aMcKearney, , 1974aMcKearney, , 1974bMalagodi, DeWeese, Webbe, and Palermo, 1973;Morse, Mead, and Kelleher, 1967;Stretch, Orloff, and Dalrymple, 1968;Stretch, Orloff, and Gerber, 1970). In most of these experiments, responding has been maintained on fixed-interval (FI) schedules, under which the first lever press after a fixed period of time produces a brief electric shock.…”

Following initial histories under a schedule of electric shock postponement, lever pressing in squirrel monkeys was maintained under fixed-interval and fixed-time schedules of electric shock presentation. No difference in either rate or pattern of responding was obtained when these schedules were presented as components of a multiple schedule. When they were presented singly for long periods of time, the fixed-interval schedule consistently maintained a higher response rate than the fixed-time schedule. The pattern of responding under both schedules was similar, typically consisting of a pause at the beginning of each interval followed by either a steady or a positively accelerating rate of responding. The results suggest that the response-shock dependency is of critical importance in the maintenance of high rates of responding under schedules of electric shock presentation, and support the general view that such responding may be conceptualized as operant behavior under control of many of the same variables that control responding under comparable schedules of food or water reinforcement.
