Week 1- Intro Flashcards
Designs to measure development
- Cross-sectional
- Longitudinal design
- Microgenetic design
What’s a cross-sectional design
Compare children of different ages at a single time
What’s a longitudinal design
- Compare children to themselves
- Children examined repeatedly over long time periods
What’s a microgenetic design
- Children are observed intensively over a short period of time
- Change occurs in this period
Evaluate cross-sectional design
+ Faster
+ Can identify differences between ages
- Uninformative about continuity of development over time
- Uninformative about individual differences within a cohort
Evaluate a longitudinal design
\+ Watch development unfold \+ Can examine the stability of individual differences over time and individual patterns of change - Practice effects - Attrition rates and bias - Expensive and takes a long time
Evaluate Microgenetic designs
+ Very detailed
+ Intensive observation can clarify process of change as it occurs
- Must know when change will happen
- No long term data about change patterns
- Narrow in focus
What approaches are used in cognitive psychology
- Experimental cognitive psychology
- Cognitive neuropsychology
- Computational cognitive science
- Cognitive neuroscience
What is experimental cognitive psychology approach
If an experiment manipulation affects one type of task but not another, we can look at the cognitive process used for tasks
What is a cognitive neuropsychology approach?
If a patient with neuropsychological deficits has deficits in some tasks but not others, we can look at the cognitive process used for tasks
What is a computational cognitive science approach?
Using simulations of cognitive processes can be used to make inferences about how processing systems might interact and the constraints a system might have for performance of cognitive tasks
What is a cognitive neuroscience approach?
Allows correlation of brain activity location and timing with specific ropes of tasks
