Evocative and function-altering effects of contingency-specifiying stimuli
Insights
Contingency-specifying stimuli (CSSs) influenced 4-year-olds' compliance. Immediate consequences and deadlines were most effective when response opportunities were immediate, while immediate consequences alone worked best for delayed opportunities.
Area of Science:
- Behavioral Psychology
- Child Development
Background:
- Contingency-specifying stimuli (CSSs) are crucial in shaping behavior.
- Understanding the distinct functions (evocative vs. function-altering) of CSSs is important for behavioral analysis.
Purpose of the Study:
- To investigate how different forms of CSSs affect compliance in 4-year-old children.
- To differentiate the evocative and function-altering roles of CSSs in this age group.
Main Methods:
- Children received daily CSSs varying in deadline (immediate/delayed) and consequence type (immediate/delayed).
- The study manipulated the presence and timing of deadlines and consequences.
Main Results:
- Immediate deadlines and consequences reliably controlled behavior when response opportunities were immediate.
- Deadlines alone influenced behavior, even without specified consequences.
- When response opportunities were delayed, CSSs were less effective, with immediate consequences and no deadline being most impactful.
Conclusions:
- CSSs function as both evocative and function-altering stimuli.
- Deadlines may act as learned aversive conditions, influencing compliance.
- The timing of response opportunities significantly moderates the effectiveness of CSSs.
Abstract:
This study examined the effects of various forms of contingency-specifying stimuli (CSSs) on the compliance of 4-year-old children, and attempted to separate the evocative vs. function-altering functions of the CSSs. Each child was presented with a series of CSSs (one per day) that differed with respect to the deadline specified (immediate or delayed) and the consequence specified for performing the task. In the second part of the experiment, the CSSs either specified a delayed deadline or did not specify a deadline. Also, the consequences that were specified were either immediate or delayed. The results showed that under conditions where the opportunity to respond was immediately available, (a) CSSs that specified deadlines and immediate consequences exerted reliable control over behavior, and (b) deadlines, whether delayed or immediate exerted some control over the behavior, even when CSSs specified no consequences for task completion. Under conditions where the opportunity to respond was delayed, (a) CSSs of any kind were less likely to exert reliable control, and (b) children were most likely to respond when CSSs specified immediate consequences and made no mention of a deadline. Results are interpreted in terms of the role of CSSs as evocative and/or function-altering and in terms of deadlines as learned aversive conditions.
