Cognitieve ergonomie als cognitive engineering.
Ab de Haan Cognitieve
ergonomie kan gezien worden als het op grond van
wetenschappelijke inzichten ontwerpen van
omgevingen, technologische en andere, zoals
communicatie methodieken en behandelmethoden, om
de menselijke cognitie te beïnvloeden en kan in
die zin gezien worden als een variant van
cognitive engineering. Hierin onderscheid zij
zich van bijvoorbeeld kunstmatige intelligentie,
die primair gericht is op de beïnvloeding van
machinale cognitie. Om iets te kunnen
beïnvloeden, moet je het wel kennen. Vandaar het
belang van fundamentele inzichten uit de cognitie
wetenschap. Tijdens de voordracht zal aan de hand
van een aantal voorbeelden dit nader worden
toegelicht. Hierbij staat met name het
perspectief van taken als uitdrukking van
(neurale) configuraties en herconfiguraties,
zoals die bijvoorbeeld in task switching,
voorkomt centraal.

A what task Introduction
  • Optimising human-computer interaction
  • Multimedia environments
  • Non-speech audio
  • Human-human communication as a starting point
  • The Stroop/Simon paradigm how are primary info
    streams influenced by secondary info streams.
  • A main task e.g. pointing in a direction,
    categorising a picture.
  • A secondary (competing) task presence of a
    stimulus aspect.

  • The task set perspective
  • "Adopting such a set is to select, link and
    configure the elements of a chain of processes
    that will accomplish a task . In everyday life,
    we constantly configure and reconfigure elements
    from our repertoire of cognitive operations and
    representational capacities to perform now one
    task, now another (Rogers and Monsell, 1995".
  • Dual task Two configurations Active.
  • Mutual interference measures (RT, errors, mental
    load) index joint use of resources and endogenous
    scheduling. General rule Avoid joint use of
    resources (e.g. experienced driving and talking)
  • Stroop task interference and facilitation
    measures index relative activation of secondary
    task with respect to primary task the
    possibility to inhibit (perceptual) urges.
    General rule avoid competitive secondary
    information, and especially information that is
    strongly cued with respect to the same response
    channel.

  • Switching between tasks.
  • Task Switch research studies the configuration
    and reconfiguration of task sets.
  • For every digit string, repeatedly name the
    digits in the string,
  • in the next string count them etc.

  • In dual tasks and stroop task no reconfiguration
    of task sets.
  • Task switch costs index (we think) the
    deactivation of one task configuration and the
    activation of the other. It is the task set with
    the greatest activation that executes the
    response. Not you.

  • Results performance data (RT/ERRORS) as Expected
  • Results op HRV not as expected
  • Expected single task generates relatively low

    task has a high mental load with low HRV.
  • Data single task low variability ( high mental
    load), doubbll task high variability ( low
    mental load)

88
  • Neuromotor Noise
  • Mental, emotional and physical load generate more
    activity in the nervous system.
  • Part of that activity is noise, random
    fluctuations in activity that are superimposed on
    the signal.
  • Symptoms
  • Noise may and disturb the execution of motor
    tasks.
  • Symptoms less accuracy, trembling etc.
  • Adaptation
  • Filtering of the noise to preserve the signal
    noise ration and to execute the movement within
    parameters. Filtering mechanisms
  • Speed up performance.
  • Co-contraction of muscles, introducing stiffens
    in the limb and thus more accurate movement.
  • Lean on something.

Conclusion
  • HRV data and Grip Force data measure the same
    construct with respect to the tasks
  • HRV is useful for non motor tasks but is not easy
    to apply
  • Grip force as measured by the squeeze mouse seems
    a useful device for safe mousing.
  • Where and what types of action (counting and
    moving) can influence one another in a double
    task
  • Measurements with Mouse feed back into the neuro
    motor noise theorie modulates the relevance with
    respect to practical applications.

  • The alternating runs task switch paradigm.
  • AABBAABBAABBAABB etc.
  • Switch Cost
  • MEAN (RT(AB)RT(BA)) - Mean(RT (AA)RT(BB)).
  • Switch Costs index exogenous and endogenous
    costs.
  • If preparation longer than e.g. 1 sec. no further
    switch cost reduction is observed. What remains
    is residual exogenous switch cost.
  • switch costs are not observed "if the
    to-be-performed tasks are uniquely cued by
    stimulus type within the experimental context
    (Arbuthnott and Frank, 2000)".
  • General rule try to avoid non unique cueing.
    E.g., if switching between editors, situate them
    at distinct locations on your screen.

Functional Brain Mapping
  • Methods employed
  • PET
  • (Vascular response)
  • fMRI
  • (Vascular response)
  • EEG and MEG
  • (Neuronal response)
  • Optical Imaging
  • (Vascular response)
  • Advantages fNIRS
  • High temporal resolution
  • Measures deoxyHb and oxyHb
  • Bedside applicable
  • Disadvantages fNIRS
  • Low spatial resolution

Multi-Channel NIRS Optical Topography
  • Advantages
  • Localize active areas
  • (brain or muscle )
  • Investigate heterogeneity in oxygenation
  • Investigate heterogeneity of flow

perceptual, fast, direct) E.g. driving a car
dissociation
140
On Task Performance (mainly Monsell, 1997) Task
set e.g. driving a car, reading a text. A mental
configuration of less or more simple elements
steering, breaking, clutching, looking, gsming
etc etc. Can be activated and deactivated. You
decide to drive, not to clutch, steer, look etc.
Automatic contention scheduling. Intention is
involved in task setting, not in execution
(monsell, 1997). The strongest activated task set
wins. The intentional task setting may be
overridden The weakness of the flesh

The strongest activated task set wins
Intention is involved in task setting Not in

Simple tasks vs. Complex tasks.
Single step vs. Multi step.

From intentional to habitual
Removal of switch costs
From conceptual to perceptual control
From conscious to unconscious
From endogenous to exogenous
Van denken naar doen
144
Simpel vs. complex tasks. Free vs. forced task
execution. A text fragment is "natural"
order selection text, selection operation?
Can the reverse be taught. Cognitive
constraints on learnability. Is it a 2nd
nature, an automated habit?. Correlations
between multiple stimuli dimensions.
Simultaneous Stroop. In time task switching,
changing association strength. Frontal lobe
development and potential task competence.
145
Endogene Controle Probleem als dezelfde
