Final answer:
According to B.F. Skinner, behavior involves observable actions influenced by operant conditioning. Out of the scenarios presented, 'lying very still' would be considered behavior as it is an action that can be externally observed and influenced through reinforcements or punishments.
Step-by-step explanation:
According to B.F. Skinner, behavior is the range of actions and mannerisms made by organisms, systems, or artificial entities in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the physical environment. Among the options provided:
- Your iPhone falling out of a hole in your pocket is not considered behavior as it is an accidental event, not an action performed by an organism.
- Snot dripping out of your nose is an involuntary physiological process, not a behavior in the Skinnerian sense.
- While thinking about scratching your arm is a cognitive process, Skinner's behaviorism primarily focuses on observable actions, not internal thoughts.
- Lying very still can be considered behavior, as it is an observable action that an organism can perform and can be affected by operant conditioning.
In the context of operant conditioning, lying very still is the option that best fits the definition of behavior according to B.F. Skinner's theory. This is because it is an action that can be influenced by reinforcements and punishments and can be measured and observed.
