practice questions Flashcards
parametric analysis
seeks to discover the differential effects of a range of values of the independent variable. example: assess the effects of different reinforcer magnitudes, (20 sec, 60 seconds, or 300 seconds of access), effect of the varied degree of the same IV is compared
Behavioral contrast effects
the phenomenon in which a change in one component of a multiple schedule that increases or decreases the rate of responding on that component is accompanied by a change in the response rate in the opposite direction on the other, unaltered component of the schedule. example: grandma scolds child for eating cookie for dinner, eating cookie at higher rate when grandma is not present and lower rate when she is.
Independent group contingency
arrangement in which contingency is presented to all members of a group but reinforcement is delivered only to those group members who meet the criterion outlined in contingency
Dependent group contingency
Criterion stated for one individual or small group, the reward for the whole group is dependent on the performance of an individual student or small group.
Interdependent group contingencies
all members of a group must meet the criterion of the contingency (individually and as a group) before any member earns the reward.
total count IOA
smaller count x larger count divided by 100= total count IOA
mean count per interval IOA
INT 1 IOA + INT 2 IOA + INT N IOA n intervals divided by 100 = mean count per interval IOA
exact count per interval IOA
number of intervals of 100% IOA x n intervals x 100 = exact court per interval IOA %
trial by trial IOA
number of trials agreement/total number of trials x 100 = trial by trial IOA %
total duration IOA
shorter duration/longer duration x 100 = total duration IOA
mean duration per occurrence IOA
dur IOA R1 + Dur IOA R2 + Dur IOA rn/ n responses with dur IOA
interval by interval IOA
number of intervals agreed/number of intervals agreed + number of intervals disagreed x 100= interval by interval IOA
scored interval IOA
calculated using only those intervals in which either observer recorded the occurrence of the behavior.
unscored-interval IOA
is calculated using only those intervals in which either observer recorded the nonoccurrence of the behavior
noncontingent reinforcement
an antecedent intervention in which stimuli with known reinforcing properties are delivered on a fixed-time or variable timer schedule independent of the learner’s behavior. 3 procedures-
- positive reinforcement
- negative reinforcement
- automatic reinforcement
