Configurational cues are based on the configuration of the stimuli, while compound cues are the combination of two or more aspects of a cue. An example of a configuration cue would be the discrimination of the words men or women on restroom doors, where the length and shape of the word is used for discrimination rather than identification of individual letters or recognition of the word in other contexts. Children with intellectual impairments may use a problem-solving approach based on configurations and context as part of their functional cues. Remember that cues may be different for each individual. This creates uncertainty in performance of actions.
Uncertainty influences preparation for a task or activity.
Cues which are given, then are not followed by completion of the task have an adverse effect upon the student's performance. Reaction time, movement time, and response time can all be affected by uncertainty. Uncertainty appears to reduce task preparation and adversely affect reaction time, motor time and response time. If you have entered a new school and are not sure where the office is, your uncertainty makes your walk slower and your movement less efficient. If you reach your destination without distraction, the next time you will move more quickly and efficiently.
