Taxis vs. Kinesis
Kinesis:
simple change in behavior in response to
stimuli
Movement without direction/random
Animals move fast when unhappy and slow when happyTaxis: an automatic movement from or to a stimuliChemotaxis – movement towards a chemicalPhototaxis – movement towards light Slide4
Animal Behavior
Behavior is either INNATE or LEARNED
Innate
: developmentally fixed. In the genes. Nature.
Learned
: modified by experience. Nurture.All animals are selfish (exception is the rare altruistic behavior). They will do whatever helps them to survive and reproduce.Slide5
Classical Conditioning
C
lassical
conditioning shows automatic and involuntary behavior that results from placing neutral signals before a reflex
.Slide6
Operant Conditioning
Operant conditioning includes reinforcement or punishment after a behavior which leads to strengthening or weakening of voluntary behavior.
Classical: uses neutral stimulus to modify behavior
Operant: uses positive and negative stimulus to modify a behavior Slide7
Stimulus-Response Experiment
Basically, we see if an external stimulus issues a modification in behavior (response) Slide8

Keep in mind
Simple is not bad. Remember, you are only testing ONE variable. You must control for everything else.
I can get you crickets and
fruit flies
. You can pick any animal you want.
Rollie pollies popular too.Make sure you can start and finish your experiment within the first 45 minutes of class. Next time you will come in and:
