developmental psych Flashcards
broad issues in developmental psych
- nature vs nurture
- genetic inheritance(nature) vs environmental factors(nurture)
- Chomsky(nativist) vs Pavlov/Skinner(behaviourist) - continuity vs discontinuity
- does development happen gradually or in distinct stages?
- Piaget (stage theory) vs Atchley (over life course) - nomothetic vs ideographic
- studying groups(broader) vs individuals - stability vs change
- whether traits remain stable or change over time - sensitive vs critical period
concept of windows in development where certain skills or traits are most easily required. - typical vs atypical
- categories vs continuum
research methods used in developmental psych
watching
- watching:
structured observation: children completing specific tasks under a controlled environment, allowing for detailed behaviour observation
- limitations -> child feels uncomfortable being watched/ structured setting
naturalistic observation: observing children in their natural environment(school, playground) to see how they behave in unstructured settings.
- limitations -> less control over variables, children unaware their being watched, ethics?
research methods used in developmental psych
asking
= interviews/ questionnairres to extract information directly from individual
- flexible interview = allows targeted questions and lots of info to be gathered but may struggle with honesty or comparison
- structured interviews = provides standardised questions allowing for comparison but lacks depth.
- parent/teacher questionairres = Effective for gathering information from caregivers/multiple perspectives, but may be limited in depth.
- child questionairre = suitable for older children who can express their feelings directly
research methods used in developmental psych
testing
- psychophysiological testing
- measures brain activity or physiological responses.
- This is focused and provides proximal data but requires consent and can be in intimidating environment (ECG caps) - standardised/ empirical testing
- Common for measuring development but may be limited by biases or discrimination.
- Everybody gets same task with same level of instructions and guidance and see how they perform
research methods used in developmental psych
analysing
- ethnography
-large case study involving study of cultural contexts, however non-generalizable to other individuals or settings - database/ archival
- Provides comparisons over time, cheaper, but data quality may be questionable. - case study
- multi-dimensional, but potentially biased, non-generalizable
general research designs
- correlational design
- explores relationship between variables but can not determine causality
Laboratory Experiments: Controlled settings allow for manipulation of variables, providing strong evidence for causality.
Field Experiments: Conducted in natural settings, they offer better ecological validity but less control.
Natural/Quasi Experiments: Study of naturally occurring events, though they may have limited control.
Longitudinal Studies: Track the same group of people over a long period. These studies can show how development changes over time but may be outdated or have sample effects.
Cross-Sectional Studies: Study different age groups at one timepoint. They can reveal generational differences but may suffer from cohort effects (i.e., differences between groups due to experiences).
Sequential Designs: A combination of cross-sectional and longitudinal methods, allowing for more dynamic insights into developmental changes.
validity in developmental research
- internal validity = the extent to which the study accurately measures the relationship between variables(cause and effect)
- external validity = the ability to generalize findings to the wider population from the sample
- ecological validity = generalise findings to real-world setting
- population validity = The extent to which results can be generalized to a larger group from your sample.
ethical issues in developmental psych
- deception = parents or child must be fully informed about the study
- vulnerable groups
- Consent/Assent: Obtaining informed consent from parents and assent from children where necessary.
- Right to Withdraw: Participants should always have the option to leave the study at any time.
- Necessity of Child Participation: Researchers must justify the inclusion of child participants to ensure it is essential for the study.
what is cognitive development?
= refers to thinking, learning, remembering, and problem solving that evolves over time.
Key areas of focus include conceptual reasoning, abstraction, language, socio-emotional development, perception, and information processing.
The goal is to understand qualitative differences in how adults and children think, recognizing that children think differently from adults.
Piagets theory of cognitive development
= Children construct their own understanding of the world, rather than passively absorbing information.
- development follows a fixed order of stages, cannot be skipped and the speed of progression may vary between children but they remain universal. (experienced by all children)
4 stages of cognitive development
Piagets theory
- sensorimotor stage
- birth to two years
- Develops object permanence (understanding objects exist even when unseen).
- Begins understanding cause and effect through deliberate actions.
- Exhibits deferred imitation (performing actions observed earlier). - preoperational stage
- age 2-7
- Advances in pretend play and symbolic representations.
- Displays egocentrism (difficulty understanding others’ perspectives) and animism (attributing life-like characteristics to objects).
- Language development continues. - concrete operational stage
- age 7-11
- Development of logical thinking and the principle of conservation (understanding that quantities remain the same despite changes in form).
- Inductive logic (specific -> general reasoning). - formal operational stage
- 12+
- Shift from logical to abstract reasoning.
- Develops deductive reasoning (general to specific).
- Engages in moral, philosophical, and political thinking.
mechanisms of change
piagets theory
schemas = mental representations that organize categories of information and experiences
adaptation = building schemas via interaction with the environment
assimilation = integrating new info into exisiting schemas (assuming all animals that “baa” are sheep)
accommodation = creating or adjusting prior schemas based on new experiences (recognizing that not all animals that “baa” are sheep).
critisism of Piagets theory
- selective sampling bias
- lack of rigour
- underestimation of children
- The theory overemphasizes the role of the child in development and neglects the social environment.
- No consideration of post-adolescent development.
- Deficit-based: Focuses more on what children can’t do rather than what they can do.
- descriptions rather than explanations
Vygotsky’s theory of cognitive devlopment
- emphasises that learning leads to development rather than the reverse (Piaget)
- role of culture in shaping development
- emphasis on social environment (interactions/ guided learning)
- role of language (internalisation)
- More Knowledgeable Other (MKO): Adults, rather than peers, provide important guidance.
- carers providing modelling and scaffolding
Vygotsky’s mechanisms of change
Elementary mental functions: Innate functions like attention, sensation, perception, and memory.
Through cultural interaction, these elementary functions evolve into higher mental functions (problem-solving, abstract thinking), which are influenced by cultural beliefs and values.
information processing perspective
- views development as a process of maturation
-Thought processes are similar at all ages but vary according to acquired knowledge and experience.
informtion processing theory of development
= development is a process of gradual maturation.
- Information is dealt with in stages, focusing on encoding, storage, and retrieval, with these processes being present across all ages but more efficient as the individual matures. (not discrete like Piaget)
- Emphasizes how internal cognitive processes (memory, attention, problem-solving) interact with external stimuli.
- IPT emphasizes internal cognitive processes, offering a more continuous and fluid model of development.
- specifies precise mechanisms
- apllicable and actionable
- little extrapolation to social/moral domains
- limited integration of biologicsl substrates
Cases Neo Piagetian theory
= Case’s theory agrees with Piaget’s concept of step-like stages, where each step represents more sophisticated cognitive abilities.
- Executive Functioning (EF) is central to explaining how/why cognitive abilities evolve using IPT. It allows for problem-solving, monitoring, and adapting strategies.
- Recognizes that children develop different abilities at varying paces
the 4 stages of cognitive structures (Cases neo piagetian theory)
- sensimotor structures = sensory input and physical actions
- interrelational structures = internal representations of objects and concepts (words, images)
- dimensional structures = simple transformations (fractions)
- vectorial structures = complex transformation sof thinking (abstract thinking)
executive functions and their role in cognitive development
= mental processes that help individuals set, monitor and achieve goals.
- higher and lower cognitive processes that control our behaviour
- includes the working memory, inhibitory control and cognitive flexibility.
- EF enable individuals to plan, make decisions, control impulses and focus attention.
- EF are regulated by prefrontal areas
- Miyake and Friedman are key theorists
the development of executive functions
- early childhood (3-5 years)
- Inhibition and working memory are the first to develop, with significant growth in the ability to listen, resist urges, and follow instructions. - pre-adolescence
- Working memory and goal-directed behaviour improve. Skills like planning and selective attention emerge (e.g., managing school tasks). - adolescence
- Peak period of integration of EF components, improving problem-solving and strategy development. - adulthood
- Some EF abilities, particularly working memory and spatial functions, begin to decline.
influence of social interaction on executive functions
Socialisation: The way caregivers and parents interact with children can influence the development of EF. For instance, positive caregiving (e.g., playing, managing impulses) fosters EF, while negative control (e.g., over-restricting decisions) can impair it.
Children with better EF are often better at regulating their behaviour in social settings, leading to better social interactions.
measuring executive function
- standardised neuropsychological tests
- behavioural checklists
- observations/ interviews
There are some issues with floor effects in assessments, where younger children may not perform tasks well enough to capture their true abilities. (minimum scores)
inhibitory control
= is a core executive function
- It involves controlling our automatic urges (attention, behaviour, thoughts, and emotions) by pausing, then using attention and reasoning to respond appropriately. Inhibitory control involves our ability to think before we react
mechanisms of change in the stages of cases neo piagetian theory
- brain maturation = improvements in the efficacy of thought
- working memory = can engage in more complex mental operations
- schemas become more automatic with use
- each stage is represented by central conceptual structures = mental frameworks used to organize information (numerical, social, spatial)
horizontal decalage = It is a lag in time in being able to understand different tasks can require the same cognitive framework.
piagets theory of moral development
- heteronomous morality (moral realism)
- ages 4-7
- morality is governed from external sources
- rules from authority figures must be strictly followed (immanent justice)
- focus on consequences, not intention - autonomous morality (mortal relativism)
- age 8-12ish
-morality becomes self governed
- Rules can be adapted; fairness involves considering others’ needs.
- Recognizes that harm can be accidental.
