Q

What is John Locke’s pov about giving the child freedom as they grow?

A

Caretakers must give children more and more freedom (gradually) as they grow older

Too much freedom at an early age can cause the child to mature more quickly

Too little freedom at a late age can cause the child to not develop their own character

Q

What are the 3 designs for examining/observing child behaviour and development?

A

1) Cross-sectional
2) Longitudinal
3) Microgenetic

44
Q

Which experimental design involves observing the behaviours of children over a short period of time?

A

Cross-sectional design

45
Q

Which experimental design involves observing the behaviours of children over a long period of time?

A

Longitudinal design

46
Q

Which experimental design involves observing the behaviours of children using different participants each time?

A

Cross-sectional design

47
Q

Which experimental design involves observing the behaviours of children using the same group of participants over time?

A

Longitudinal design

48
Q

What are the advantages of following a cross-sectional design?

A

1) Quick

2) Common and easy to find participants who are willing to participate in a short-term study

3) Yields useful data about differences among age groups

49
Q

What are the disadvantages of following a cross-sectional design?

A

1) Not developmental (you don’t study the children as they get older)

2) Averages across individuals (in reality growth is not smooth and consistent but cross-sectional studies average out the results and make it look like development is a smooth process)

3) Cohort effects

50
Q

Define cohort effects

A

Generational difference

e.g.

80-year-olds may not develop aggressive behaviour when playing violent video games simply because when they were growing up, they never played video games

Meanwhile, current 10 year olds become aggressive because they grew up playing video games

51
Q

What are the advantages of following a longitudinal design?

A

1) Indicates the degree of stability of individual differences over long periods

2) Reveals individual children’s patterns of change over long periods

52
Q

What are the disadvantages of following a longitudinal design?

A

1) Difficult to keep all participants in the study (some participants might drop out over time)

2) Repeatedly testing children can threaten the external validity of the study

53
Q

Which experimental design involves observing children intensively over a relatively short period of time whilst the children are thought to be going through some developmental changes?

A

Microgenetic design

54
Q

What are the advantages of following a microgenetic design?

A

1) Intensive observation of changes while they are occurring can reveal process of change

2) Reveals individual change patterns over short periods in considerable detail

55
Q

What are the disadvantages of following a microgenetic design?

A

1) Does not provide information about typical patterns of change over long periods

2) Does not reveal individual change patterns over long periods

56
Q

What are the ethical issues in developmental research (what must researchers take responsibility for)?

A
  • Ensure the research does not harm the children physically or psychologically
  • Obtain informed consent from parents/guardians and the child (if s/he is old enough to understand)
  • Preserve the anonymity of the children who take part
  • Counteract any negative outcomes and correct any inaccurate impressions that arise during the study
57
Q

How do infants learn and develop?

A

1) Infants’ brains experience synaptogenesis (creation of new synapses and connections)

2) The more infants learn, the more synaptic connections they will have

58
Q

When does learning begin?

A

Prenatally

59
Q

What are the 6 types of learning that help infants learn about their environment?

A

1) Habituation
2) Perceptual Learning
3) Statistical Learning
4) Classical Conditioning
5) Instrumental Conditioning
6) Observational Learning

60
Q

What type of learning involves a decrease in responsiveness to repeated stimulation?

A

Habituation

61
Q

What is Habituation?

A

Habituation = A decrease in responsiveness to repeated stimulation

(when they are presented with the same stimulus over and over again but then they lose interest in the stimulus)

62
Q

How can we tell that the infant has learned something through Habituation?

A
  • The infant has a memory representation of the
    repeated, now-familiar stimulus
  • The speed with which an infant habituates is
    believed to reflect the general efficiency of the
    infant’s processing of information
  • Some continuity has been found between these measures in infancy and general cognitive ability later in life
63
Q

Who conducted a well-known visual habituation experiment?

A

Maurer and Maurer

64
Q

Which experiment involved presenting infants with pictures of faces and when the face first appeared, the infant’s eyes widened and stared intently? But by the 5th appearance, the infant did not pay attention to it anymore.

A

Maurer and Maurer’s Habituation experiment

65
Q

What did Maurer and Maurer do in their visual Habituation experiment?

A
  • Presented 3 months old with pictures of faces
  • At the 1st appearance of the face, the infant’s eyes widen and she stares intently
  • With 3 more presentations on the same
    face, the infant’s interest wanes and a yawn
    appears (habituation)
  • By the face’s 5th appearance, other things are
    attracting the baby’s attention
  • When a new face finally appears, the infant’s
    pays attention to the new face (dishabituation)
66
Q

Who conducted a well-known auditory habituation experiment?

A

Eimas

67
Q

What did Eimas do in their auditory Habituation experiment?

A
  • Allow infants of 2 months to suck on a dummy that is connected to a computer and measure baseline sucking rate
  • Present phoneme (/pa/) repeatedly
  • Sucking rate first increases and then
    infant habituates (i.e., returns to baseline sucking rate
  • Present new phoneme (/ba/)
  • Infant dishabituates (i.e. sucking rate
    increases again)
68
Q

Apart from not paying attention to the same stimulus and decreased sucking rate, what else happens when infants habituate?

A

Their heart rate decreases

69
Q

Apart from staring intently at an unfamiliar stimulus and increased sucking rate, what else happens when infants dishabituate?

A

Their heart rate increases

70
Q

What type of learning involves using our abilities to see, hear, smell, taste and touch to make sense of the world?

A

Perceptual learning

71
Q

What is perceptual learning?

A

When infants use their perceptual abilities (abilities to see, hear, smell, taste and touch) to search for order and regularity in the world around them

72
Q

Define Differentiation

A

The ability to associate a certain stimulus that changes with an element that stays the same

e.g.
Stimuli that changes = Voices of different people (pitch)

Element that stays the same = Voices are auditory (can only be heard)

Differentiation = The ability to tell that the voices come from 2 different people based on the pitch

73
Q

Define Affordances

A

When you know that certain objects and/or stimuli require you to do/perform different tasks

e.g.
An infant must learn that small objects can be picked up but large ones do not

e.g.
When playing with a toy that requires you to put the correct shapes into the correct holes:

Infants must learn that round shapes can be pushed into the container though the round hole but square and star shapes cannot

74
Q

When playing with a toy that requires you to put the correct shapes into the correct holes:

Infants must learn that round shapes can be pushed into the container though the round hole but square and star shapes cannot

What term is used to define this knowledge?

A

Affordance

75
Q

The ability to tell that the voices come from 2 different people based on the pitch

What term is used to define this knowledge?

A

Differentiation

76
Q

Define statistical learning

A

Involves picking up information from the
environment, forming associations among stimuli that occur in a statistically predictable pattern

Certain events occur in a predictable order; from quite early on, infants are sensitive to the regularity with which stimulus follows another

77
Q

The ability to tell which shape comes next after recognising the pattern/order in which the shapes are arranged

What term is used to define this type of learning?

A

Statistical learning

78
Q

What does Statistical learning supposedly help with?

a. Language
b. Perception
c. Differentiation
d. Affordances

A

Language learning

79
Q

Define Classical Conditioning

A

A form of learning that consists of associating an initially neutral stimulus with an unconditioned stimulus

80
Q

Who initiated classical conditioning?

A

Pavlov

81
Q

Fill in the blank

It is thought that many (………….) responses (both positive and negative) are initially learned through classical conditioning

A

Emotional

82
Q

How does classical conditioning work?

A

1) Neutral stimulus is paired with unconditioned stimulus repeatedly

  • NS always comes BEFORE the US

2) After many repeats, the neutral stimulus becomes a conditioned stimulus which induces a conditioned response

3) We induce a CR when we see the CS, even before we see the US

83
Q

Who conducted classical conditioning on dogs?

A

Pavlov

84
Q

What did Pavlov do in his dog classical conditioning experiment?

A

1) Dogs naturally salivate (UR) when presented with food (US)

2) Pavlov presented dogs with a ringing bell (CS) just before feeding them food (US)

3) After a few repetitions, the ringing bell alone was enough to make the dogs salivate (CR)

85
Q

Define operant/instrumental conditioning

A

Involves learning the relation between one’s own behaviour and its consequences

What happens if you behave a certain way (will you get a reward or punishment?)

86
Q

Who initiated operant/instrumental conditioning?

A

BF Skinner

87
Q

What will operant/instrumental conditioning teach you?

A

Teaches you to repeat behaviours that
lead to rewards and give-up behaviours
that lead to punishment

88
Q

Define contingency relation

A

Reinforcement or Punishment (consequences) after you behave a certain way/ perform a particular action

89
Q

What are the 2 types of reinforcements (rewards) in operant/instrumental conditioning?

A

1) Positive reinforcement
2) Negative reinforcement

90
Q

A child gets given sweets as a reward for sleeping early the night before

What type of reinforcement is this?

A

Positive reinforcement

91
Q

A child cleans the whole house and her mum decided that she is no longer grounded

What type of reinforcement is this?

A

Negative reinforcement

92
Q

What is the difference between positive and negative reinforcement?

A

Positive = When you do something good, you get given a reward/something good

Negative = When you do something good, something unpleasant/bad gets taken away from you

93
Q

We eat to avoid feeling hungry

What type of reinforcement is this?

A

Negative reinforcement

94
Q

What is the aim of reinforcement?

A

To encourage children to repeat a desirable behaviour

95
Q

What is the aim of punishment?

A

To discourage children to repeat an undesirable behaviour

96
Q

A child gets scolded by their mother for breaking a vase

What type of punishment is this?

A

Positive punishment

97
Q

A child’s iPad gets taken away from them because they refuse to wash the dishes

What type of punishment is this?

A

Negative punishment

98
Q

What is the difference between positive and negative punishment?

A

Positive = When you do something bad, you get given a punishment/something bad

Negative = When you do something bad, something good/a reward gets taken away from you

99
Q

What is it called when behaviour is neither reliably rewarded nor penalised?

A

Extinction

100
Q

Infants of depressed mothers tend to smile less and show lower levels of positive affect than do infants of nondepressed mothers

Is this an example of …

a. Reinforcement
b. Punishment
c. Extinction

A

c. Extinction

101
Q

What type of learning involves observing the behaviours of others and attempting to behave the same?

A

Observational learning

102
Q

Who recently debunked that young infants can imitate?

A

Oostenbroek et al. (2016) suggests that young infants cannot imitate

Infants can only imitate when they’re older (by 15 months)

103
Q

Define Observational learning

A

Observing the behaviours of others and attempting to behave the same

104
Q

What term is used when infants imitate adults based on the reason for the particular adult’s behaviour?

A

Imitating intentions

105
Q

Define imitating intentions

A

In choosing to imitate a model, infants appear to pay attention to the reason for the person’s behaviour (intentions)

106
Q

When 18-month-olds see a person apparently try, but fail, to pull the ends off a dumbbell, the infants imitate the action by actually pulling the ends off

What does this suggest about how a child learns?

A

Children perform actions that adults intended to do and not what the adults actually did (Meltzoff, 1995)

Children do not imitate a mechanical device at all
