This theory was originally proposed in order to explain discriminated avoidance learning, in which an organism learns to avoid an aversive stimulus by escaping from a signal for that stimulus. Two processes are involved: classical conditioning of the signal followed by operant conditioning of the escape response: a) Classical conditioning of fear.
The controlling effects of stimuli are seen in quite diverse situations and in many aspects of behavior. For example, a stimulus presented at one time may control responses emitted immediately or at a later time; two stimuli may control the same behavior; a single stimulus may trigger behavior A at one time and behavior B at another; a stimulus may control behavior only in the presence of ...
If the stimulus does not warrant a strong enough response, it is said to not reach absolute threshold, and the body does not react. However, if the stimulus is strong enough to create an action potential in neurons away from the photoreceptor, the body will integrate the information and react appropriately.

When the extinction of a response has occurred, the discriminative stimulus is then known as an extinction stimulus (SΔ or S-delta). When an S-delta is present, the reinforcing consequence which characteristically follows a behavior does not occur. This is the opposite of a discriminative stimulus, which is a signal that reinforcement will occur.
The minuscule signals, which result from the stimuli, enter the cells must be amplified and turned into an sufficient signal that will be sent to the brain. [1] A sensory receptor's adequate stimulus is determined by the signal transduction mechanisms and ion channels incorporated in the sensory receptor's plasma membrane.
For example, if one has adapted to something (like an odor or perfume), one can not consciously force themselves to smell that thing. Neural adaptation is tied very closely to stimulus intensity; as the intensity of a light increases, one's senses will adapt more strongly to it. [21] In comparison, habituation can vary depending on the stimulus.
[1] [5] [6] General PIT occurs when a CS is paired with one reward and it enhances an operant response that is directed toward a different rewarding stimulus. [1] [5] [6] Neurobiological state factors (e.g., appetite and satiety states, stress level, drug states such as intoxication and withdrawal, etc.), and particularly the motivational state ...
