Just noticeable difference is a constant proportion of the intensity of an initial stimulus is this weber's law?
difference threshold
What do you call the tendency to respond to a stimulus that is similar but not identical to a conditioned stimulus?
Stimulus Generalization
What response is caused by a neutral stimulus?
The neutral stimulus does not cause any response. It is paired with the Unconditioned Stimulus until it is turned into the Conditioned Stimulus.
How does a neutral stimulus become a conditioned stimulus?
How are the strongest associations between the conditioned stimulus and the unconditioned stimulus formed?
The strongest association is formed when we present the conditioned stimulus about half a second before the unconditioned stimulus.
In positive feedback the initial stimulus produces a response that the stimulus?
exagerrates the stimulus
When the initial stimulus produces a response that reinforces the stimulus the mechanism is called?
positive feedback
What term is defined as the visual impression that remains after the initial stimulus is removed?
afterimage
What kind of feedback mechanism is it when it causes the initial stimulus to decline?
negative feedback
When an initial stimulus produces a response that exaggerates stimulus called what mechanism?
Exaggerating the stimulus is also seen as amplifying the stimulus. This is seen in outer ear hair cells.The mechanism you refer to is probably a positive feedback mechanism: more of the stimulus causes more of the stimulus. This is in contrast to a negative feedback mechanism, whereby more stimulus results in processes that strive to attenuate (lessen) that stimulus.
Do negative feedback systems operate in such a way that the initial stimulus is shut off or reduced?
Yes
Just noticeable difference is a constant proportion of the intensity of an initial stimulus is this weber's law?
difference threshold
In a negative feedback loop the effector organ produces changes that are?
opposite in direction to the change produced by the initial stimulus
What were Mr baker initial experience?
He was brave and strong with all he can be in the army.
Where is SAN located on the heart?
The sinoatrial node (SAN) is located within the walls of the right atrium. It is from here the initial stimulus for contraction of the atria originates.

1) Free will. 2) Time (the situation has changed). 3) Experience (you get used to it).
Signal to which an organism responds?
stimulus
