| Question | Answer |
|---|---|
| What is an animal's behavior? | It's what it does and how it does it, usually in response to stimuli in its environment. |
| Behavior ecology is | the study of behavior in natural environments from an evolutionary perspective |
| Innate behavior is | inborn behavior referred to as instinct |
| Learned behavior is | behavior that's been modified in response to environmental experience |
| Behavior depends on | physiological readiness. |
| Many behavior patterns depend on | motor programs (muscle actions). |
| An animal habituates (learns) to | irrelevant stimuli. |
| Imprinting occurs during an | early critical period. |
| Imprinting is | a type of social learning based on early experience. |
| In classical conditioning a reflex becomes | associated with a new stimulus (can opener gets dogs attention at dinnertime). |
| In operant conditioning (i.e. rat presses down on bar to get pellet of food), | spontaneous behavior is reinforced. |
| Insight learning uses recalled events to | solve new problems. |
| The reasons animals play may be to | practice behavior. |
| Biological rhythms | affect behavior. |
| Migration involves interaction among | biological rhythms, physiology, and envioronment. |
| What is necessary for social behavior? | Communication |
| Do some animals communicate by scent? | Yes |
| Dominance hierarchies are | social rankings. |
| Many animal defend | a territory. |
| Some species that engage in social behavior | form societies. |
| Society | An actively cooperating group of individuals belonging to the same species and often closely related. |
| Social insects form | elaborate societies. |
| Vertebrate societies tend to be | relatively flexible. |
| Culture | Behavior common to a population, learned from other members of the group |
| What does sociobiology explain? | Human social behavior in terms of adaptation. |
| What type of mates de animals seek? | Quality mates. |
| What do courtship rituals ensure? | That the male is a male and a member of the same species. And allows the female to check out the male. |
| Sexual selection favors | polygnous matings systems. |
| Some animals | care for their young. |
| Cooperative behavior | Also called mutualism (like group hunting where each animal in the group benefits). |
| Reciprocal behavior | a type of cooperative behavior (when one animal helps out another with no immediate benefit -- animal repays debt later). |
| Altruistic behavior can be explained by | inclusive fitness. |
| Altruistic behavior | when one behaves in a way that seems to benefit others rather than itself, with no potential payoff. |
| Cooperative behavior may have | alternative explanations. |
