tapetum lucidum
Definition
part of eyes that uses light twice to enhance it at the cost of clarity
Term
tympanic membrane
Definition
aka the eardrum-- mechanically conducts sound to cochlea

Definition
the attribution of human characteristics/behavior to an animal
Term
sensitization period
Definition
this period starts on the 7th week of puppy life( or 6-8 weeks)
Term
Thorndike's Law of effect
Definition
antecedent> behavior> consequence
Term
latent inhibition
Definition
repeated pairing of stimulus with no reinforcement
Term
primary socialization
Definition
first half of socialization period(3-5 week)
Term
tyrosine
Definition
precursor to melanin and dopamine
Term
behavioral inhibition system
Definition
recognition of signals anticipating punishment- reduces behavior
Term
amygdala
Definition
fear center of the brain
Term
parasympathetic
Definition
part of the automatic nervous system that operates during rest & digestion
Term
hypothalamus
Definition
part of brain that links to the endocrine systems =, has a lot of input from brainstem
Term
tapetum nigrens
Definition
part of eyes that absorbs light
Term
secondary socialization
Definition
weeks 6-12 of socialization period
Term
back chaining
Definition
teaching/shaping end behavior 1st( behavior at the end is strongly reinforced)
Term
classical conditioning
Definition
type of associative learning where the 1st event predicts the 2nd and behavior is elicited( involuntary or reflexive)
Term
forward chaning
Definition
behaviors at beginning are strongly reinforced
Term
chaining
Definition
ordering of complex tasks
Term
extrinsic reinforcer
Definition
reward is external to behavior
Term
jackpotting
Definition
rewarding for excellence
Term
neonatal period
Definition
first 12 days of puppy development
Term
behavioral activation system
Definition
behavioral system that works with reward gaining and avoidance of punishment-- increases behavior--
Term
social dominance relationships
Definition
these emerge around 10-16 weeks
Term
norepinephrine
Definition
neurotransmitter which when present decreases aggression
Term
affective aggression
Definition
defensive and offensive displays
Term
time/energy budget
Definition
the proportions of time that animals spend doing different behaviors
Term
teeth emerge
Definition
this developmental event occurs around day 19 of puppy life ( transitional period)
Term
jumpstarting
Definition
rewarding for motivation
Term
coprophagy
Definition
nutrient investigation of fecal matter
Term
acquisition
Definition
1st stage of learning where animal is still learning what is expected of them
Term
fluency
Definition
2nd stage of learning when animal can do behavior without thinking
Term
generalization
Definition
3rd stage of learning when knowledge is relevant in a lot of situation
Term
positive reinforcement (r+)
Definition
a behavior is strengthened by producing or prolonging some desirable consequence
Term
maintenance
Definition
last stage of learning when behavior becomes a permanent part of behavior repertoire
Term
metacentric
Definition
having a centromere in the meridian position so that the arms are of equal length
Term
babymorphism
Definition
dog-child model where dogs are thought to have the mental characteristics of a 1-5 year old child
Term
ethogram
Definition
a catalogue/table of all the different behaviors/activities observed in an animal
Term
shadowing
Definition
prompting in the process of fading
Term
achondroplasia
Definition
hereditary condition in which the growth of long bones by ossification of cartilage is retarded( limited to extremities)
Term
Tinbergen's 4 questions
Definition
these are the 4 descriptions of behavior and development of an ethogram
Term
socialization period
Definition
weeks 3-12 of puppy development
Term
paedomorphosis (neoteny)
Definition
prolongation of puppylike or juvenile characteristics
Term
lupomorphisms
Definition
dog-wolf model that assumes that only superficial aspects of wolf/dog behavior changed in domestication
Term
naturalistic experiment
Definition
experiment that looks at behavior in a natural setting
Term
negative reinforcement (R-)
Definition
a behavior is strengthened by terminating, reducing or avoiding some undesirable consequences
Term
quiet attack
Definition
predatory behavior
Term
dichromatic
Definition
only can see 2 color tones (yellow and blue)
Term
intrinsic reinforcers
Definition
reward is inherent in the behavior itself
Term
depth perception
Definition
overlap in visual fields of right and left eyes (40-60 degrees in dogs)
