The nature of Elicited Behaviour
The Reflex
A specific relation between a stimulus and a corresponding
response that is a consequence of the organization of the nervous
Sensory neuron:
Motor neuron: carry signals away
Afferent: arrival
Efferent: exiting
Supernormal stimulus: ex. Wearing red lipstick, plastic sugery
Not necessarily found in nature
Consummatory behaviour: taking a nut, putting it in your mouth
Building a nest: appetitive
Fertilizing: consummatory
Beating his tail to show off: appetitive
Swimming in a zig-zag pattern: appetitive
Effects of repeated stimulation
- decar was wrong, you don’t always see the same response
habituation is stimulus specific. When you experiment with a lemon the first
10 times, you become immune to it. The 11th time there was a booming
response to the lime, the sudden change
Effects of repeated stimulation
- the new face shown to the Caucasian infants was 70% made up of the old
face and 30% made up of an alternate race
- Caucasian notice more differences in own race, Asians notice differences in
peoples faces of their own race
sensory adaptation: ex. When someone takes a picture of you with flash and
you cant see anything

rules out fatigue: lemon lime salivation experiment. The response was
specific to the lemon because results picked up when lime was used
1) habituation helps you to attend to stimuli around you that may be
important: false but can be true???
2) studies of sensitization need to rule out fatigue as a possible explanation
for the change in behaviour to a stimulus over time: false
3) a decrease in responsiveness over time could happen because of sensor
4) a control for sensory adaptation is showing that habituation is stimulus
specific: true
The dual-process theory
1) the habituation process is the pbservable…: false
2) the sum of the habituation and sensitization processes will be a
habituation or sensitization effect: true
3) false
4) false
5) the habituation process occurs in the S-R system: true
6) false
