Final answer:
Preference assessments typically use Trial Based Methods and Single Stimulus. These are strategies used in psychology to identify reinforcers that can be used to encourage specific behaviors through preference selection.
Step-by-step explanation:
The methods typically used for conducting preference assessments are Trial Based Methods and Single Stimulus. These methods are part of the broader category of assessing what an individual prefers, which can be used for reinforcing desired behaviors. In psychology, especially within the realm of applied behavior analysis, preference assessments help determine stimuli that the person or animal might find reinforcing. During a trial-based method, the individual is presented with different choices across multiple trials, and their selections help determine their preferences. The single-stimulus, also known as the 'successive choice' method, involves presenting one item at a time to determine if the individual approaches or interacts with the stimulus, indicating preference.
When discussing reinforcement schedules like partial reinforcement or intermittent reinforcement, these strategies involve not reinforcing a behavior every time it occurs, as opposed to continuous reinforcement where the behavior is reinforced every time. This can lead to more resistant behavior patterns when the reinforcement is later reduced or removed.
