Q
What is the aim and importance of Developmental Psychology?
A
Aim
- to understand what babies are born with and what do they learn
> this allows us to understand the origins of skills and knowledge
Importance
- understanding and preventing development disorders
> autism, depression, future criminality
> environmental and biological underpinnings
- knowing more about children’s development helps to inform social policy
- understand what kinds of experiences are important to healthy development
- prevention
4
Q
Define Developmental Nativism
A
Patterns of thought and ability emerge from genetics
5
Q
Define Developmental Empiricism
A
Environment is what shapes development
6
Q
Name the 6 Developmental Periods
A
Prenatal
- conception->birth
Infancy
- 0-18 months
Preschool
- 18m-4y
School age (young and old)
- young = 5-7y
- old = 8-12y
Adolescence
- 13-20y
Adulthood
- young = 21-30y
- middle = 31-60y
- late = 60y+
7
Q
Describe the Prenatal Developmental Period
A
conception -> birth
8
Q
Describe the Infancy Developmental Period
A
0-18 months
- preverbal
9
Q
Describe the Preschool Developmental Period
A
18 months - 4 years
- rapid development of language and social skills
- memory and reasoning
10
Q
Describe the School Age Developmental Period
A
Young (5-7y) and Old (8-12y)
- complex ideas, abstract reasoning
- more experience with non-family members
- (preschool show higher aggression)
11
Q
Describe the Adolescence Developmental Period
A
13-20y
- puberty
- social and sexual development
- complex reasoning
- impulse control
12
Q
Describe the Adulthood Developmental Period
A
Young (21-30y), Middle (31-60y), Late (60y-death)
- role in life develops
- career peaking, child rearing
- declining physical and mental skills, some improvement of old age tasks
13
Q
In which developmental stage is the peak of life happiness?
A
Mid-late adulthood
14
Q
Define Developmental Continuity
A
Development is continuous
- each new event is built on previous experiences
- developmental cascade
15
Q
Define Developmental Discontinuity
A
Development occurs via abrupt changes in ability
16
Q
Define Critical Periods
A
- periods (ages) during which certain experiences are required for normal development to occur
17
Q
Define Sensitive Periods
A
- age range where specific experiences are optimal for development to occur in a typical way
18
Q
Describe the Domain-General approach to Development
A
- the development of new skills requires the development of previous skills
- tend to have different, complimentary systems
19
Q
Describe the Domain-Specific approach to Development
A
- skillsets that are separate, and aren’t needed to compliment each other
- mathematical reasoning and moral judgement
20
Q
What are Individual Contextual Influences?
A
- the idea that contexts may influence the way we behave
- as apposed to the idea that we behave the same way across different contexts
21
Q
Cultural Context in Development
A
- children across cultures develop differently
22
Q
Define the Ecological Context of Development and the 4 systems an individual interacts with
A
- different levels of contextual influence that effect the child, that differ in exposure in relation to developmental age
An individual is influenced by:
Microsystem
- family, sibling, peers
Mesosystem
- interrelationships between the microsystem
Exosystem
- extended family, neighbourhoods, mass media, parent’s work environment
Macrosystem
- economic system, culture
23
Q
What is the Lifespan Perspective
A
- different environments due to generation (cohort effect)
- causing people within cohorts to share trends
24
Q
Describe the role of Theories
A
2 roles of theories:
- organise and integrate existing information into coherent and plausible ideas in regard to child development
- generate testable hypotheses
> need to be empirically tested for validity, but can also change and evolve
25
John Locke's view on development
- children are born into the world tabula rasa (blank slate)
| > empiricism
26
Descartes' view on development
contradicts Locke, stating the mind imposes order on the environment, based on inherited features
> nativism
27
William James on development
- children are born into the world without any knowledge and learn to understand it
28
Behaviourism
(Watson, Thorndike, Pavlov, Skinner)
Learning based on experience
- focus on behaviour and learning
- principles on learning theory observed in adults could be used to model learning theory within children
(empiricism)
Uses the model of Operant Conditioning
> behaviour is learned by reinforcement
+ positive or negative
Uses the model of Classical Conditioning
> behaviour is learned by association
Pavlov's Dog example:
- NS (footsteps) paired with an UCS (food), which causes salivation (UCR)
- NS becomes a CS when paired with the UCS, and the salivation due to the CS is the CR
Watson's Little Albert example:
- NS -> CS = rat
- UCS = loud noise
- UCR -> CR = crying/distress
29
Maturational Theory
Opposition to behaviourism
- inspired by Darwin's evolutionary theory
- the emergence of children's skills are largely determined by inheritance
- (nativism)
- based on the observation that certain skills tend to develop in a certain order (twin study)
- stating that there are biological timetables, set in advance by out genetics and evolution
30
Psychodynamic Theory and the 3 parts of personality
Freud and later Erikson
- Believed the developing personality had 3 parts:
id -> ego -> superego
(developing in that order)
id (0-1)
- instinctual drives
(present in infants)
ego (1-3)
- gratifying our needs through socially acceptable means
(late childhood -> adolescents)
superego (3-6)
- internalising societal values and morals, developing a conscience
31
Psychodynamic Theory and the 5 stages of Psychosexual Development
Freud theorised that within these stages of development, if these psychosexual milestones needs weren't satisfied, then it would lead to fixation within that stage
```
Oral
Anal
Phallic
Latency
Genital
```
Oral Stage (0-1) {id}
- fixation on putting things in the mouth i.e breast
+ provides good self esteem
- becomes orally fixated, mistrust of others, fear
Anal Stage (1-3) {ego}
- potty trained
+ learns independence and personal power
- becomes codependent on others
```
Phallic Stage (3-6) {superego}
- discovers sexual desires, unconscious desire to the opposite sex parent (oedipus / electra complex)
```
```
Latency Stage (6-12)
- from sexual desires to focussing on social desires
```
```
Genital Stage (12+)
- child likely forms their sexual identity
```
32
Ethological Theory and the Oxytocin system
Ethology - the idea that behaviours observed in other species can be taken as comparisons or those in humans
Lorenz (imprinting) found that baby ducks will follow the adults of any species, they are imprinted to follow adults
John Bowlby (attachment theory) studied the bond between child and caregiver
Oxytocin system
- a hormone that enhances social bonding and interaction (love hormone)
- found that humans and dogs oxytocin systems both act similarly and are stimulated when they look in each other's eyes
33
Theories of Cognitive Development (6)
Social Learning Theory (Vygotsky)
Constructionism (Piaget)
Evolutionary Theories
Information-Processing Theories
Connectionist Model
Developmental Neuroscience
34
Social Learning Theory and the 6 stages of learning
Proposed by Vygotsky
- put emphasis on the social and cultural context in development
- stated cognitive process are socially mediated
- importance of the Zone of Proximal Development
Theory:
- children learn behaviour from their environment through 6 stages
> stage completion is dependent on certain factors
```
Modelled Behaviour
(input)
```
Attention
- experience / relationship with the model / context
Retention
- rehearsal / recall the experience
Reproduction
- concept matching / use of feedback
Motivation
- external incentives / self-evaluation / social comparison
Matched Behaviour
(result)
35
What is the Zone of Proximal Development?
The idea that the best way to learn a skill is to gain proximity to someone that is proficient in that skill (i.e. caregiver and child)
36
What did Bandura's test involving the Bobo doll show?
- the children exposed to the adults using violent behaviour on the doll, replicated it
- showed that children can model behaviours
37
Constructionism and the 4 stages
Developed by Piaget
- children progress through stages in the same way
- children of similar ages tend to get the same things wrong (or right)
- thinking changes qualitatively with age
Stages:
Sensorimotor (0-2)
- aware of what's immediately in front of them
- no object permanence
Pre-operational (2-7)
- object permanence
- engage in creativity
```
Concrete Operational (7-12)
- develop logical concrete reasoning
```
```
Formal Operational (12+)
- symbols and abstract concepts (maths and science)
```
38
What is Object Permanence
The ability to know something still exists when you can not directly see or interact with it
39
Evolutionary Theory of Development and it's limitation
- critical components of human evolutionary change are in areas of the brain
- specific Modules within the brain are responsible for many cognitive functions
> these are developed to process those specific types of information
> these modules are Computationally Encapsulated (many are independent of one another)
> an individual's modules could be affected by personal inheritance
> the modules come online as the brain and boy mature
Noam Chomsky's Language Acquisition Device (LAD)
- the modules
- nativistic
Limitation
- the theory can't be reliably tested, since the exact boundaries of modules can't be specified
40
Information-Processing Theories
- the idea of internal mental processes
- looks at a flow of information through the cognitive system
- beginning with the input, ending with response
41
Connectionist Model
- large sets of interconnected nodes that influence each other:
```
Input units
- have weighted connections to
Hidden units
- have weighted connections to
Output units
```
- brain acts like a computer
42
Developmental Neuroscience
The use of brain scanning to look at neural development
43
Data collection in Developmental Psychology
- often uses questionnaires (impossible for children)
- for children often it is direct observation
Methods of data collection:
- Children's self-reports
- Reports by family / teachers / peers
- Observation
- Interviews
- Biological and physiological
- Measures of the PNS
- EEG / PET / FRMI
44
Evaluate Observational Studies
- ecologically valid
- can't prove causation since it's a correlational method (allows researchers to relate certain experiences to each other and assess the strength of these relations)
45
Evaluate Experimental Designs
- Field Experiments rely on natural observation, ecological validity but risk observer bias
- Natural experiments are quasi-experimental, no random assignment
- Lab experiment is a research design allowing investigators to determine cause and effect by controlling variables and treatments
- Experimental Group
- Control Group
- Random Assignment
- Often difficult to ensure ecological validity (natural behaviour)
46
Evaluate the Correlational Method
- low control over IV
- low control over DV
- medium generalisability of findings
47
Evaluate the Lab Experiment
- high control over IV and DV
| - low generalisability of findings
48
Evaluate the Field Experiment
- low control over DV
- medium control over IV
- high generalisability of findings
> ecological validity
49
Evaluate the Natural Experiment
- low control over DV
- low control over IV
- high generalisability of findings
> ecological validity
50
Describe the Cross-Sectional Method
Comparing different age levels at the same point in time
51
Describe the Longitudinal Method
Study the same subjects over various time points
52
Describe the Sequential Method
Combines both cross-sectional and longitudinal methods
| > compares people of different age levels, at different points in time
53
Important considerations in research methods (3)
- validity (internal)
- replicability
- generalisability (external validity)
