• Behavior – the way an organism reacts to change • Stimulus – change in the organisms environment (can be inside or outside the organism’s body) • Response – reaction to the change • Usually involves multiple body systems interacting and working together • Innate – behaviors an organism is born with •Ex: a spider weaving a web • Learned – behaviors acquired due to an organism’s experiences (not born with these behaviors) • Habituation • Classical Conditioning • Operant Conditioning • Insight Learning • DO NOT WRITE THIS SLIDE IN YOUR NOTES!!! • Habituation – response is slowed or stopped due to being exposed to the stimulus a number of times •Simplest form of learning •Ex: Ragworms will retreat to their burrows when a shadow passes over them. They will eventually stop retreating to their burrows when shadows continually pass over them. • Classical Conditioning – mental connection is made between a stimulus and an event •Ex: Pavlov’s dog • Every time Pavlov fed his dog he would ring a bell. Eventually the dog would salivate every time it heard the bell (even if food was not present). • Operant Conditioning – behavior is learned through rewards and punishments •Ex: Training a dog • Most dogs are trained by giving it a reward (treat, toy, affection) when it does the desired behavior (sit, stay, etc.). Dog will not receive the reward if it does not do the behavior. • Insight Learning – applies prior knowledge to a new situation •Most complex form of learning •Performed mostly by humans •Ex: Chimpanzee experiment • Bananas were placed out of reach for a chimp. The chimp stacked boxes on top of one another to climb up and reach the bananas. • Imprinting •Newborn ducks have an innate behavior to follow the first object they see (usually their parent) •They do not know what the object will look like when they are born •They must learn which object(s) to follow and not to follow • Many animals respond to periodic changes in their environment (daily or seasonal cycles of behavior) •Ex: dormancy/hibernation, migration, circadian rhythm (daily pattern) • Behaviors help animals to reproduce •Ex: courtship – behavior that helps animals choose the healthiest mate • Social Behavior – how animals interact with their own species • Some behaviors protect territories •Ex: aggression, competition • Communication • Use of visual signs • Ex: movement, color • Pheromones – chemicals emitted that affects an animal’s behavior • Ex: animals “marking” their territory • Vocal communication • Ex: birds chirping, humans speaking • Language – combines sounds, signals, and gestures • Most complex form of communication • Known to be only used by humans
