Unit 2 Course Outcomes

• Students should define key vocabulary related to behavioral contexts.
• Students should be able to identify examples of behavioral responses and response classes.
• Students should be able to identify examples of environmental stimuli and stimulus classes.

Unit 2 Readings

• Read Chapter 2 in Cooper et al. (2020)
• Review key terms and concepts PDF file
• 3 articles focusing on response prompting, stimulus control and setting events.

Unit 2 Weekly Assignments

• Discussion Board: Identify antecedent stimuli, influence of stimulus classes on responses, functional and structural responses, and environmental modifications. Use at least two sources. Respond to at least two peers over two days.
• CBA Learning Modules: Complete Modules B-1 & B-2. Include a screenshot of log and 8-10 sentences.
• Pass/Fail Assignment: Explore stimulus-response relations and the three-term contingency.

Lecture - What is Behavior

• Behavior is defined as everything people do.
• ABC's of behavior (Antecedent, Behavior, Consequence) are explored.
• The Antecedent is what happens before a behavior.
• The Behavior is what is happening using detailed, objective language.
• The Consequence is what happens after a behavior.
• Examples of behaviors and contexts are discussed.

Stimulus and Responses

• Stimulus is defined as an energy change that affects an organism through receptor cells.

• Humans have receptor systems that detect stimulus changes outside and inside the body.

  • Examples of stimulus include: visual, auditory, tactile, gustatory, olfactory.

• Examples of stimulus classification are presented - Formal (physical characteristics) - Temporal (when it occurs relative to a behavior) - Functional (effect on behavior)

• Responses refer to single occurrences of behaviors.

  • Structural: Describing the behavior physically
  • Functional: Describing the effect of the behavior on the environment

• A change in the environment (stimulus) elicits a reaction from the organism (response).

Reinforcement

• Reinforcement increases the future frequency of a behavior in similar conditions.
  • Positive: Behavior followed by the presentation of a stimulus that increases its future occurrence. (Examples: activities, toys, food, money)
  • Negative: Behavior followed by the removal of a stimulus that increases its future occurrence (Examples: demands, social settings, tasks, homework).

Punishment

• Punishment decreases the future frequency of a behavior in similar conditions.
  • Positive: Behavior followed by the presentation of a stimulus that decreases its future occurrence (Examples: scolding, lecturing, reprimanding, corporal punishment).
  • Negative: Behavior followed by the removal of a stimulus that decreases its future occurrence (Examples: time-out, response cost, removal of desired item).

Quick Questions

• Examples of antecedents, behaviors, and consequences are presented in various scenarios.
• Discussion is focused on identifying common stimulus-response patterns in experiences, and distinguishing between reinforcement and punishment.
