Across
1.The natural selection that favors altruistic behavior by enhancing the reproductive success of relatives.
3.The formation at a specific stage in life of a long-lasting behavioral response to a particular individual or object
5.Associative learning in which an arbitrary stimulus becomes related to a particular outcome (dog salivating when bell is rung)
6.One male mating with many females, most common form of polygamous mating
10.Provided by the outside work, something to which a response will be directed (e.g. Konrad Lorenz in his greylag geese experiment)
11.A loss of responsiveness
12.Through learning, an organism changes its behavior based on experiences and its environment
13.An animal aiding a member of the same species who is not closely related
14.Mated individuals remain together for a longer time, forming stronger pair-bonds
18.Mated individuals form no long-lasting relationships or strong pair-bonds
19.The idea that a gene can proliferate itself throughout a population by causing an individual to behave altruistically in helping members of the same species that it is closely related to (who also have that gene) reproduce.
21.The process of knowing represented by awareness, reasoning, recollection, and judgement
23.The process of relating one situation to another.
25.Chemical substances used by animals to communicate. Most often utilized by mammals and insects and usually used for reproduction
26.Behavior consistently observed in a species that is developmentally fixed (instinct)
28.Trial-and-error" learning, in which an animal learns to associate a behavior with a reward or punishment
29.An individual from one sex mates with several of the other
Down
2.A limited developmental phase during which certain behaviors can be learned
4.The mechanistic explanation of “how” a behavior (or other aspect of an organism’s biology) occurs or is modified; that is, how a stimulus elicits a behavior, what physiological mechanisms mediate the response, and how experience influences the response.
7.A sequence of unlearned acts that is essentially unchangeable and, once initiated, usually carried out to completion. Directly linked to simple stimuli.
8.A change in activity or turning rate in response to a stimulus
9.A contest that determines which competitor gains access to a certain resource, often food or a mate
15.rB > C ; r=coefficient of relatedness, the fraction of genes that are shared
16.A representation in the nervous system of the spatial relationships between objects in an animal's surroundings.
17.The evolutionary explanation of “why” a behavior (or other aspect of an organism’s biology) occurs, that is, the benefit to survival and reproduction or the evolutionary significance of the behavioral act.
20.Opposite of polygyny, one female mates with many males
22.An oriented movement toward (positive) or away from (negative) some stimulus.
24.The scientific study of how animals behave, esp. in their natural environments.
27.Ways in which an animal behaves that decreases individual fitness but increases the fitness of the population.
