Document Summary
An elicited behaviour is one that can be automatically drawn out by a certain stimulus. Re ex- a relatively simple, automatic response to a stimulus. Startle response- a defensive reaction to a sudden, unexpected stimulus; involves the tightening of skeletal muscles as well as hormonal and visceral changes. Orienting response- automatically positioning ourselves to facilitate attending a stimulus; involves major body movement such that we automatically turn in response to an unfamiliar noise. Re ex arc- a neural structure that underlies ,amy re exes and consists of a sensory neuron, interneuron, and a motor neuron. We begin withdrawing our hand from a ame before feeling any pain. The exion response uses the spinal corde so we can react much quicker than if the message had to travel up to the brain and then back down to our limbs. Xed action patterns (instincts)- a xed sequence of responses elicited by a speci c stimulus (sign stimulus/ releaser)
