Answer:
Both Pigeon A and B
Explanation:
Peak shift is a term that describes the conditions in which the peak of the generalization gradient moves away from the position of S+ in the direction away from the S-. This implies that, peak shift can be determined if the S+ and S - tigger the existing factors during different training in a graded manner.
Thus, if both S+ and - has mutual characteristics, then a major part of those characteristics will be triggered by both stimuli, thus, the stimulating experience of S+ will override or revoke the experience or training of S-.
Hence, since both pigeon A and B, had the S+ 800Hz tone training initially, with elemental theories, it is determined that, both will produce most peak shift phenomenon.
Note:
S+ is a stimulus showing availability of reinforcement
S- is a stimulus showing lack of reinforcement.
Answer:
Type of support surface
Nutritional supplementation
Explanation:
Variable
This is simply an element, feature, or factor that is prone to change or be altered. There is the independent and the dependent variable.
An Independent variable
This is simply refered to as a variable that is deliberately altered or changed to observe its effect on the dependent variable. It is that variable that a researcher or a scientist alters or changes and you have control over. They are the factor being tested in an experiment.
An example is the liquid used to water each plant in an experimental studies.
