Animal Behavior 9 Flashcards

Terms Definitions
Recognition
Informational signaling
Play communication
Intention signaling
cnidaria
jellyfish and hydra
Lions
Only truly social cat.
learned behavior
has to be taught
habituation
suppression of normal/regular stimuli that becomes useless in purpose…spontaneous recovery occurs when the stimulus is no longer applied or modification of stimulus
Konrad Lorenz
discovered the principle of imprinting. Studied instinctive behavior in birds
Feedback loops
All hypothalamic releases are regulated by _______. (most are negative)
estivation
state of reduced metabolism in conditions of extreme heat (ex. desert animals)
Relatedness
Probability that two individuals share allele through common descent - actual genes not shared (all humans share ALL genes)
B. F. Skinner
behaviorism; pioneer in operant conditioning; behavior is based on an organism's reinforcement history; worked with pigeons
Steroid Hormones
Lipid soluble, slow acting, diffuses straight through membrane and impacts multiple systems because it acts on DNA.
ultimate causation
The evolutionary explanation for a behavioral, physiological, or morphological response, in contrast to proximate causation; the immediate mechanisms that underlie a response.
Animal Behavior
-Important for an organism's survival and for the sucessful reproduction of offspring-may enable one animal to oucompete others of its own species-ethology (the study of....and its evolutionary origins)
instinctive behavior
instinct- complex pattern of behavior that has several parts
negitive reinforcement
stimuluting brain pleasure centers for the LACK of a certain behavior, (reward for not doing),
kin selection
The idea that evolution has selected altruism toward one's close relatives to enhance the survival of mutually shared genes
Activational effect
Specific levels of a steroid to activate adult patterns of sexual behavior, transient effects, not permanent.
Occam's razor
states that explanations should be no more complicated then necessary
courtship behavior
behavior males and females carry out before mating
conditioning
the establishment of a new reflex by adding neutral to unconditioned stimulus
Blood donation
Example of altruism in humans we benefit from donating blood not because we may benefit from blood donations, but because we feel better about ourselves when we do good deeds.
classical conditioning
a type of learning in which an organism comes to associate stimuli. A neutral stimulus that signals an unconditioned stimulus (US) begins to produce a response that anticipates and prepares for the unconditioned stimulus. Also called Pavlovian or respondent conditioning.
Cooperation
-enables a behavior to be done as a group more successfully than each can do alone-ex: hunting in packs
simple reflexes
controlled at the spinal cord which is a connector between a afferent(rcptr) and efferent(mtr) neuron….very useful for simple animals
what is habituation?
a loss of responsiveness to stimuli that convey little or no new information. (i.e. getting used to stimuli)
conditioned stimulus…conditioned response
tuning fork was used to make dog think that food is coming
what are the 4 questions that behavioral ecologists try to answer?
1. what stimulus elicits the behavior2. how does the animal's experience during growth and development influence the response3. how does the behavior aid survival and reproduction4. what is the behavior's evolutionary history?
