WHY?

3. Theory building
Cognitive Load Theory (CLT)
 Overload causes..
 .. to stop learning
 .. to become slower
 .. to make cognitive mistakes
Normal
load
Overload
Cognitive Fit Theory (CFT)
 Lower extraneous load by..
 .. adapting learning/problem solving material to task
 .. adapting learning/problem solving material to user

3. Theory building
Extended Cognitive Fit Theory (ECFT)
 Lower intrinsic load by..
 .. adapting problem solving strategy to user
 .. adapting problem solving strategy to task
Cognitive Fit Theory (CFT)
 Lower extraneous load by..
 .. adapting learning/problem solving material to task
 .. adapting learning/problem solving material to user

3. Theory building
Structured Process Modeling Theory (SPMT)
 Lower intrinsic load by..
 .. adapting process modeling strategy to user
 (.. adapting process modeling strategy to task)

EXPLANATORY THEORY

4. Method development
Development of a digital one-hour treatment
Structured Process Modeling Method (SPMM)
 Measure cognitive variables
 Select fitting strategy
 Explain and train strategy (=treatment)
 Apply strategy
PRESCRIPTIVE THEORY
METHOD

4. Method development
 Results
 10-15%* of variation in quality..
 30%* of variation in modeling time..
 60%* of variation in modeling effort..
.. could be explained by only 8 variables from our theory
These are:
 Serialization degree, structuredness, and fit
 Learning style, field dependency, and need for structure
 Interaction effects with time and effort
R2 values of linear regression models with p-values below 0.05

Research proposals
 Generalization to problem solving
 Extended Cognitive Fit Theory (ECFT)
• Fit between problem solving and user
• Fit between problem solving and task
 Differentiated problem solving
• Descriptive + explanatory + prescriptive
• Theory + method
• For programming, writing, composing
• And problem solving in general (=ECFT)

2. Research gap
 Effects of fit ask for differentiation
 Research is giving up on differentiation
where it is clearly relevant for the future
 Cognitive Psychology has strong focus on learning
 Differentiation in learning is difficult to study
 difficulty to measure types of load
 difficulty to measure end results of learning
 role of ‘challenge’ in learning
 The focus on learning is too complex
 intangible end results, long term
 Lack of process orientation
 variable values evolve during the process

2. Research gap
 Shift the focus to problem solving
 tangible end results, short term

3. Proposed solution
 Study differentiated problem solving
 Width a broad scope
 Different (types of) users, problems and strategies
 But not too broad
 Scope of individual complex design problems
 High risk
 It’s all about balance!
 High gain
 Breakthrough in cognitive differentiation research
 Crossover opportunities between domains

3. Proposed solution
 With a versatile and generalist P.I. (me )
 Data-driven process improvement expert
 Technically skilled (programming, experimenting,
data/process mining, statistics, visualization)
 Relatively unbiased by the psychology field (again )
 But capable of setting up an international research
network and successful research collaborations quickly
 With experience in training, coaching, and supervising
 With vision (pioneering PPM research)
 With top-tier publications (ESWA, DSS)
 With passion

 Do you have any questions?
 Do you have feedback?
 Do you have ERC experience?
Thanks for you attention!
