The effects of variable-interval and fixed-interval signal presentation schedules on the auditory evoked response.
Averaged auditory evoked responses to 1000-Hz 20-msec tone bursts were obtained from normal-hearing adults under two different intersignal interval schedules: (1) a fixed-interval schedule with 2-sec intersignal intervals, and (2) a variable-interval schedule of intersignal intervals ranging randomly from 1.0 sec to 4.5 sec with a mean of 2 see. Peak-to-peak amplitudes (N1P~) as well as latenci...
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...
متن کاملPreference between variable-ratio and fixed-ratio schedules: local and extended relations.
Although it has repeatedly been demonstrated that pigeons, as well as other species, will often choose a variable schedule of reinforcement over an equivalent (or even richer) fixed schedule, the exact nature of that controlling relation has yet to be fully assessed. In this study pigeons were given repeated choices between concurrently available fixed-ratio and variable-ratio schedules. The fi...
متن کاملVariable-ratio schedules as variable-interval schedules with linear feedback loops.
The mathematical theory of linear systems has been used successfully to describe responding on variable-interval (VI) schedules. In the simplest extension of the theory to the variable-ratio (VR) case, VR schedules are treated as if they were VI schedules with linear feedback loops. The assumption entailed by this approach, namely, that VR and VI-plus-linear-feedback schedules are equivalent, w...
متن کاملEvaluation and comparison of job stress among security workers with fixed and shift work schedules in Municipality of Tehran
Municipality of Tehran with huge number of employees and with the aim to reduce stress and promote the work efficiency, seriously wants to achieve suitable and utilizable studies. Osipow's job stress test is one of the best tools to reach this aim. Data population includes securities building of municipality of Tehran (88 persons from region 18 and 72 persons from region 20), who were randomly ...
