A

exons

25
Q

__________ - 97% of human DNA is non-coding; can turn a gene on or off

A

introns

26
Q

______ & ______ define a “gene”

A

promoter & stop regions

27
Q

__________ - one of 2+ versions of a gene

A

allele

28
Q

___________ - alleles that differ by a single base or nucleotide (following mutation); occurs once every 1500 bases

A

single nucleotide polymorphism (SNP)

29
Q

___________ - allels that differ because of inversions; insertions; deletions; duplications (following mutation); surprisingly common

A

copy number polymorphisms (CNP)

30
Q

__________ explanations: __________ - how the behaviour works

A

proximate; mechanism

31
Q

___________ explanations: _________ - why the behaviour exists

A

ultimate; function

32
Q

__________ - explanations: __________ - changes in the individuals across the lifespan

A

ontological; development

33
Q

________ - explanations: ________ - changes in the organism across generations

A

phylogenetic; evolution

34
Q

Approach that suggested life preservation & sexual instincts (life & death instincts); function of the unconcious

A

Freudian Approach

35
Q

Approach that suggested that humans have many instincts; function of consciousness

A

Functionalism Approach

36
Q

Approach that focused on stimulus-response associations; mind is a “black box”; environmental determinism; people are blank slates; general ability to learn is only instinct

A

Behaviourism Approach

37
Q

Approach that reintroduced the mind to psychology; brain is the “hardware”; mind is the “software”; mind processes all information equally

A

Cognitive Revolution

38
Q

Model that claims human though and behaviour their own providence; human behaviour divided among different disciplines with little interdisciplinary communication; mind is a general purpose information processor; ignores ultimate and phylogenetic explanations; person as a blank slate

A

Standard Social Science Model

39
Q

Approach that says the mind is a collection of programs (modules); specialized software (domain specific); product of natural selection; mind processes some information better than others

A

Evolutionary Psychology

40
Q

__________ - proximate mechanisms and adaptive value of animal behaviour

Examples:
- Imprinting (Konrad Lorenz)
- Attachment (John Bowlby)

A

ethology

41
Q

_________ - Extended the ethology approach to human behaviour (culture art, ethics, religion)

Examples:
- Edward O. Wilson
- Social sciences emphasized learning and socialization

A

Sociobiology

42
Q

__________ - Psychology that studies adaptive value of psychological mechanisms

A

Evolutionary Psychology

43
Q

___________ - Psychology about comparisons made across species (humans, chimps, gorillas)

A

Comparative Psychology

44
Q

Explain the “Evolution = Genetic Determinism” misconception

A
  • Genes code for proteins, not behaviour
  • Selection comes from the environment
  • Adaptations evolve to help orgnaisms deal with environmental challenges
45
Q

Explain the “Evolved Behaviour is Inflexible” misconception

A
  • Behaviour requires environmental input
  • Must know the cause of behaviour to modify it
46
Q

Explain the “Adaptations are optimally designed” misconception

A
  • Designed to solve problems in the ancestral environment, not the modern environment
  • Developmental constraints
  • Costs must be outweighed by benefits
47
Q

Explain the “Cultural Differences prove there are no universals” misconception

A
  • Psychological mechanisms are universal
  • Behaviour is variable
48
Q

Explain the “Humans evolved from monkeys” misconception

A
  • Chimps are not monkeys
  • Humans evolved from a common ancestor with chimps (and monkeys)
49
Q

Explain the “Humans are an advanced/higher/more evolved species” misconception

A
  • Evolution is not goal directed
  • Humans are different from other species, no better no worse
  • Other species have culture, language, memory, etc.
