ANSI 3623 Exam 1 UPDATED Exam
Questions and CORRECT Answers
animal behavior - Correct Answer- a response to changes in the internal/external environment
basic principle #1: behavior responses - Correct Answer- behavior responses occur as a result
of changes in the internal and/or external environment of the animal i.e. a dog bark arouses a
flock of sheep and elicits escape behavior, orienting sheep away from the dog
stimulus - Correct Answer- a thing or event that causes a reaction; may cause certain behavior
patters that stem from internal (hormonal) changes or external changes (stimuli perceived
through visual, auditory, olfactory, or tactile cues)
frequency - Correct Answer- determined by the type of change
basic principle #2: stimuli response - Correct Answer- not all stimuli will elicit a response in
an organism; an animal is capable of perceiving only a limited portion of its external
environment
how animals sense and perceive their environment - Correct Answer- use sense organs; sight,
hearing, taste, small, and touch
sense capabilities - Correct Answer- certain senses have limitations or are overly sensitive
across species; may filter out potential stimuli or have poor capabilities to take in all
components of stimuli
olfactory in humans vs. pigs - Correct Answer- humans perceive only a fraction of the
olfactory chemicals of stimuli compared to pigs
limitations in stimulus processing - Correct Answer- some stimuli perceived by an animal
may not have functional significance; i.e. herbivores can sense and small a piece of meat, but
it may have little or no significance to the animal
,cause of unresponsiveness to certain stimuli - Correct Answer- may occur as a consequence
of learning/habituation to certian stimuli (response of dairy calves when milk bottle trailer
drives by);
may occur until a stimulus takes on a certain significance through experience or learning
(calves turned out to pen or pastures- unresponsive to fencing until they run into it)
basic principle #3: predictability of behavioral responses - Correct Answer- behavioral
responses are not always predictable; animals often respond differently to stimuli at different
times and under different circumstances i.e. seasonally breeding species will exhibit sexual
and aggressive behaviors that change across seasons
agonistic behaviors - Correct Answer- aggression; may depend on the presence or absence of
other animals
between animal variation - Correct Answer- inter-animal; different animals respond different
ways
within animal variation - Correct Answer- intra-animal; one animal responds differently at
different times of the day or year
goal of behavior research - Correct Answer- determine the probability that a certain
behavioral response occurs from a stimulus under specific circumstances, rather than
predicting what will happen
scala naturae - Correct Answer- scientific concept proposed by Aristotle (most common for a
long time); living beings were classified on an ideal pyramid that represented non-living and
the simplest animals on the lower levels with complexity increasing progressively toward the
top, occupied by human beings
Jean-Baptiste Lamarck - Correct Answer- first biologist to describe a complex theory of
evolution and behavior
Lamarck's theory - Correct Answer- inheritance of acquired characteristics; animal's organs
and behavior can change according to the way they are used; influenced Charles Darwin
, main concern of early animal behaviorists - Correct Answer- evolution of behavior and
understanding of behavior in terms of natural selection
Darwin's book of evolutionary theory - Correct Answer- "The Expression of the Emotions in
Man and Animals"
Romanes - Correct Answer- Darwin's protege; formalized the comparative method of
comparing behavior of taxonomically unrelated organisms to gain insight into the evolution
of emotional stress
Douglas Spalding - Correct Answer- 1841-1877; wrote numerous papers on the relationship
between instinct and life experience and environment; studied imprinting; concentrated on
behaviors that were instinctive or natural and occur in all members of a species under
specified circimstances
Spalding's experiment - Correct Answer- hatched eggs using steam to examine effects
without the mother hen
ethograms - Correct Answer- a description of the main types of behavior with their
frequencies of occurrence; provided an objective, cumulative database of behavior;
constructed by Douglas Spalding
behavior developed hand in hand with what other areas of study - Correct Answer-
endocrinology, neurology, reproduction, physiology
Arnold Adolph Berthold - Correct Answer- Swiss/German physiologist; father of behavioral
endocrinology
Berthold's experiment - Correct Answer- first formal endocrinology experiment in 1849;
noticed behavioral (aggression, sexually active) and physiological (secondary sex
characteristics) differences in roosters vs. hens or capons
capons - Correct Answer- castrated roosters
Berthold's proposal - Correct Answer- proposed some "unseen" difference between hens and
roosters that account for observational differences
