Schedule-induced polydipsia as a function of fixed interval length.
Rats were trained to bar-press for Noyes pellets on an FI schedule which was increased serially through several values from 2 sec to as high as 300 sec. Concurrently, water was freely available. As FI length was increased, the degree of polydipsia increased linearly to a maximum value.
متن کاملTolerance to effects of cocaine on behavior under a response-initiated fixed-interval schedule.
Tolerance to effects of cocaine can be modulated by schedules of reinforcement. With multiple ratio schedules, research has shown an inverse relationship between ratio requirement and amount of tolerance that resulted from daily administration of the drug. In contrast, tolerance to the effects of cocaine on behavior under multiple interval schedules generally has developed regardless of interva...
متن کاملConcurrent drinking by pigeons on fixed-interval reinforcement schedules.
Three experienced pigeons were exposed to at least ten consecutive 100-min sessions on each of three food-reinforced fixed-interval (FI) schedules: FI 50-sec, FI 100-sec and FI 200-sec. Water was freely available. Drinking was largely confined to the first third of each fixed interval, and the mean sessional water intake was directly related to the food-reinforcement rate for each animal. The a...
متن کاملImpulsivity, intelligence, and discriminating reinforcement contingencies in a fixed-ratio 3 schedule.
Research conducted in academic contexts suggests a moderating effect of impulsive behavior on the relationship between aptitude and achievement. According to these studies, intelligence scores being equal, higher levels of impulsivity have an adverse effect on achievement (Helmers, Young, & Pihl, 1995; Vigil-Colet & Morales-Vives, 2005; Zeidner, 1995). The present study aims to contrast the afo...
متن کاملFixed-time schedule effects in combination with response-dependent schedules.
We evaluated the effects of fixed-interval (FI), fixed-time (FT), and conjoint (combined) FI FT reinforcement schedules on the responding of 3 adults who had been diagnosed with schizophrenia. Responding on vocational tasks decreased for 2 of 3 participants under FT alone relative to FI alone. Responding under FI FT resulted in response persistence for 2 of 3 participants. Results have implicat...
