• A)0.33 eV
• B)0.21 eV
• C)0.42 eV
• D)0.16 eV
• E)0.48 eV

Definitions:

Unwanted Response

A behavior or reaction that is undesired or negative, often leading to adverse outcomes or consequences.

Stimulus Discrimination

The ability to distinguish between different stimuli, often used in behavioral psychology to describe how organisms learn to respond differently to various signals.

Higher-order Conditioning

A form of learning in which a stimulus is paired with a previously conditioned stimulus, creating a new conditioned response.

Conditioned Stimulus

A previously neutral stimulus that, after becoming associated with an unconditioned stimulus, eventually comes to trigger a conditioned response.
