Final answer:
Behaviors are distinct from thoughts and emotions; they can be directly observed and measured, whereas thoughts and emotions are internal and cannot be observed.
Step-by-step explanation:
Behaviors differ from thoughts and emotions in that they are observable and measurable. Observable means that behaviors can be witnessed or seen by others, while measurable means that behaviors can be quantified or objectively assessed. For example, if a person is smiling, that behavior can be observed and measured in terms of the duration or intensity of the smile.
This means that behaviors are responses to stimuli that can be directly seen and quantified. In comparison to thoughts and emotions, which are internal processes that cannot be directly observed, behaviors can be witnessed and studied by others. For example, innate behaviors such as mating rituals and communicative actions are instinctual responses visible to an observer, while learned behaviors like imprinting or conditioning change based on experiences and can be measured through changes in an organism's actions.
