Theme 5A Flashcards
Neuroeducational techniques vs methods
Neuroeducational techniques: means of gathering data
Neuroeducational methods: how these techniques are used to answer research questions
Research techniques Qualitative vs Quantitative
Quantitative
experimental (setting)
fixed context/surrounding looking at/changing variables statistics
testing hypotheses
Qualitative: natural setting/real situation open minded, no fixed assumptions generates ideas/creativity involvement, subjective (?) closeness of fit between data and theory
Research techniques Types
o Questionnaires o Observation o Interviews o Focus groups o Thinking aloud o Eye tracking
Questionaires + and -
+ efficient way of collecting facts
data amenable to quantification Internet - wide range reaching people comparable, merge data
- difficult facts, bias
answers might not give wanted option
Observation + and -
+ observe dynamics of behaviour rich data
recording (video/audio) natural setting
- no control over variables lot of data, choice, analysis transcription > subjective?
Semi-structured interviews
+ obtaining information and gaining insight qualitative data
in depth, follow-up questions, change order
- not standardized: order, way of asking time consuming, trained staff
difficult to compare
lot of data, analysis difficult
access to participants
Focus groups
+ obtaining information and gaining insight Qualitative data
Multiple opinions
- not standardized: order, way of asking Time consuming, trained staff
Difficult to compare
Lot of data, analysis (?)
Multiple opinions
Thinking out loud
+ Insight in thoughts/processes during the task
- Unclear when it affects task performance Coding
Aim: Insight in invisible thought processes during a task
> Level 1 verbalization: inner speech
> Level 2 verbalization: recoding into verbal codes
> Level 3 verbalization: intermediate scanning, filtering and generating processes. Attention to additional information
> Not the same as introspection
> During the task, not retrospective
> Not asking for disturbing verbalizations, such as explanations
Eye tracking
- Does not interfere with other cognitive processes
- Attention = where one looks
- More difficult = longer fixation times
Sociacultural discourse analysis
o Observation: use of language and types of talk generated
o Language is a cultural tool
o Focus on the content and function of language, and how shared understanding is developed within a specific social context
Grounded theory analysis
Inductive research – discovery of theory from data Glaser & Strauss, 1969 Iterative process
Starts with active, immediate codes, continues with increasingly abstract codes
Interpretation by researcher
> To avoid strong researcher bias: Engagement in the field and testing
interpretation towards participants perspectives (
> Discussion with multiple scorers until consensus
RCT
+ Causality: whether an intervention works(compared with the control condition)
- Pure randomization may lead to unequal groups when N < 200
Random allocation of subjects to conditions
Controlled: With a control group
Trial: Experiment with an intervention
