1 Mar 2016 Depth of response (the maximum percentage decrease from baseline in the sum of diameters of target lesions) was also assessed as a post We continued baseline for at least five sessions and until the following stability criteria were met in each context: (a) the standard deviation of the response rates during baseline was no more than 50% of the mean rate of responding; (b) the experimenters determined responding to be steady via visual inspection, or the trend was opposite that of the treatment goal (i.e., an upward trend); and (c) no more than 20% of the baseline data points were in the range targeted for treatment during FCT. Proportion of baseline response rates in the rich component was greater than proportion of baseline response rates in the lean component both during extinction and renewal. The majority of subjects showed a higher proportion of baseline response rates in the first three sessions of extinction (4/7, 5/7 and 5/7, in sessions 1, Her baseline rates of requesting attention averaged 0.36 responses per minute (SD = 0.09). Implementation of the DRL schedule reduced responding to a mean of 0.04 responses per minute (SD = 0.02), and she never exceeded the specified limit of responses (0.1 per minute). Baseline response rates affect resistance to change. The effect of response rates on resistance to change, measured as resistance to extinction, was examined in two experiments. In Experiment 1, responding in transition from a variable-ratio schedule and its yoked-interval counterpart to extinction was compared with pigeons.

Neural adaptation or sensory adaptation is a gradual decrease over time in the responsiveness Also, in neural adaptation there is a sense of returning to baseline from a stimulated response.

Rate of reinforcement and session duration as determinants of within-session patterns of responding FRANCESK.McSWEENEY Washington State University, Pullman, Washington Rats pressed levers for Noyes pellets or keys for sweetened condensed milk reinforcers deliv ered by multiple schedules. Session length and baseline rates of reinforcement were Session length and baseline rates of reinforcement were varied in two experiments. Rates of responding increased during the early part of the session and then decreased for both responses and reinforcers, as well as for all subjects and values of the independent variables. Changes in response rates across the session sometimes exceeded 500%. Horizonntal dotted line represents baseline rate of responding. Three features of the data in Fig. 1 are noteworthy. First, there was no systematic effect of reinforcement rate on the long-term persistence of Ext-key response rates. Response rates decreased faster on the Ext schedule concurrent with the VI 180 s schedule for Pigeon 970 and Baseline data has two purposes (1) to show function and (2) to determine if an improvement has been made. Basically baseline data is going to tell you what road to take and it will also make sure you are continuously on the right track. No baseline data = no map. Accuracy of discrimination, rate of responding, and resistance to change Article (PDF Available) in Journal of the Experimental Analysis of Behavior 79(3):307-21 · June 2003 with 65 Reads The first task in a reversal design is to measure the baseline rate of behavior, which describes the behavior in a normal situation before the intervention. The baseline period (referred to as phase A) is continued until the rate of the response becomes stable. 307 journal of the experimental analysis of behavior 2003, 79, 307–321 number 3(may) accuracy of discrimination, rate of responding, and resistance to change john a. nevin,jessica milo,amy l
