Q

Bateman’s principle

A
  1. females should be the choosier sex because eggs are biologically expensive to produce and because a female’s reproductive success is more limited than a male’s.
  2. A female’s greater choosiness in mates should translate into a greater variance in the reproductive success of males

Q

A

when an association between an unconditioned stimulus and a response prevents an individual from respoding to another stimulus or causes the individual to respond less strongly to the second stimulus

Q

copying

A

-When the observer repeats the actions of the model and receives some kind of reward for doing so
-does not need to be novel, the individual most likely would have attempted the behavior at some point anyway

Q

honest indicators

A

true indicators of male genetic quality; the sender displays a reliable (honest) signal to females that cannot be replicated. Ex: peacock feathers

Q

imitation

A

A new behavior learned from others that manipulates the surroundings in a novel way in the interest of achieving a goal. Example: the other monkeys in Imo’s group observe her and learn how to wash sweet potatoes themselves.

Q

instrumental conditioning

A

occurs when a response made by the animal is reinforced; also known as operant/goal-directed learning

21
Q

intersexual selection

A

Form of sexual selection in which individuals of one sex choose which individuals of the other sex to take as mates

22
Q

intrasexual selection

A

Form of sexual selection whereby members of one sex compete with each other for access to the other sex

23
Q

Law of effect

A

If a response in the presence of a stimulus is followed by a positive event, the association between the stimulus and the response will be strengthened.

24
Q

learning

A

a relatively permanent change in behavior due to experience

25
Q

leks

A

a gathering of two or males that perform different courtship displays to attract females, common in various bird species

26
Q

local enhancement

A

When an individual is drawn to a particular area because it observed another individual in that location

27
Q

nuptial gifts

A

Prey presented by members of one sex to members of the other sex during courtship.

28
Q

oblique cultural transmission

A

-Oblique cultural transmission is information being learned across generations from an adult who are not parents to younger animals that are not offspring or in other words learning from old to young in non-relatives.
-For example rhesus monkeys and learning about the danger of snakes.

29
Q

overshadowing

A

When the learned response to an unconditioned stimulus (US1) is stronger if it is presented alone versus when it is paired with a second unconditioned stimulus (US2).

30
Q

Pavlovian/Classical conditioning

A

first developed by Ivan Pavlov; the experimental pairing of a conditioned and unconditioned stimulus

31
Q

phenotype

A

The observable characteristics of an organism

32
Q

phenotype plasticity

A

the ability for an organism to produce different phenotypes depending on environmental conditions

33
Q

response rate

A

rate at which behavior repeats

34
Q

runaway sexual selection

A

Sexual selection where the female prefers a specific trait among males, so that trait gets selected for. This continues for generations while the females prefer that the trait becomes even more exaggerated. There is no limiting factor in developing the trait, so it continues to become exaggerated in a positive feedback loop.

35
Q

Second-order conditioning

A

After an original conditioned response (CR) has been learned from conditioned stimulus 1 (CS1) a scientist will pair a new stimulus with CS1 and if the new stimulus elicits the same CR when used by itself then it becomes a second conditioned stimulus (CS2). Scientists can keep adding new conditioned stimulus until it becomes habituated or too far away, or overshadowed, etc. For example, adding the light with the blue stick and now the mouse hides when the light comes out.

36
Q

Sensitization

A

When an organism becomes more and more sensitive to a stimulus over time

37
Q

Sensory bias

A

When a male trait first emerges that is preferred by females that elicts a neurobiological response that is already in place of females; usually not associated with mating preferences.

38
Q

sex

A

types of gametes an individual can produce

39
Q

sexual imprinting

A

young imprint on the behavior and morphology of adults, most likely their parents, use these characteristics to guide selection of mates.

40
Q

social learning

A

learning by observing others

41
Q

teaching

A

The process wherein an individual offers an immediate benefit to the student(s) without obvious self-gain, the student(s) is naive to the skills being taught, and the teacher’s aid helps the student(s) gain such new skills or knowledge much faster than they could learn without help.

42
Q

tradition

A

When a new behavior emerges and then becomes common within a group as a result of social learning.

43
Q

Unconditioned stimulus (US)

A

a stimulus that elicits a vigorous response in the absence of training

44
Q

Vertical cultural transmission

A

The method of passing information between generations where a parent either teaches or performs a behavior that their offspring repeat.

45
Q

overshadowing

A

when two or more stimuli are present, one stimulus produces a stronger response than the other because it is more ‘relevant’

46
Q

learnability

A

the ability to learn under certain conditions

47
Q

latent inhibition

A

the reduced ability to learn the relevance of a stimulus that is paired with either an adverse/positive stimulus

48
Q

social facilitation

A

the mere presence of a model, regardless of what it does, is thought to facilitate learning on the part of the observer
