Flashcards in Lecture 11 'Neuroergonomics' Deck (11):

(Q. 19). How have researchers such as Parasuraman et al. (2000) related models of human information
processing to models of automation?

Any or all of the four stages of human information processing can be supported by


(Q 20). What was Lee and Moray’s (1994) key finding about trust and automation?

People will use automation if their trust in the automation is higher than their self-confidence
in their own ability to control the system.


What are two neuroergonomics examples of physical work applications?

> Role of cerebral functions in control of motor aspects of work (EEG, ERP, fNIRS)

> Central brain mechanisms involved in fatigue (EEG)


What are three neuroergonomics examples of cognitive work applications?

> Mental workload and resource theory
> Vigilance and mental fatigue
> Training and neuroadaptive systems


Just et al (2008) simulated driving carried out alone and concurrently with an auditory-sentence-verification task, what were the findings?

fMRI = parietal cortex showed lower activation with task (compared to driving without task); demonstrated independence of perceptual/cognitive, verbal/spatial and focal/ambient visual processing resources


Neuroergonomics reveals individual differences in responding, awareness which could help what?

selection and training


What are four reasons why automation is a good idea?

1 > If hazardous for humans to do (e.g. refueling nuclear power plant)

2 > If too difficult/error prone for humans (e.g. have higher control)

3 > To help people do difficult task (e.g. advise)

4. To get rid of expensive human employees in interests of economic rationalism (e.g. ATMs) *controversial*


What are five problems in automation?

1. Automation reliability (component/software, end-user set up, mismatch in automation+human understanding)

2. Automation + workload (too great)

3 . Loss of skill and knowledge

4. Loss of job satisfaction: Just serving automation

5. Human trust in automation


What is the four-stage model of human information processing?

Sensory processing > Perception/Working memory > Decision making > Response selection


What is the 'substitution myth'?

Assumption that you can successfully substitute components of human roles/tasks with technology


What five factors contribute to human-centred automation?

1. Keep human informed on what automation is doing and why

2. Keep human trained: avoid erosio of manual skills

3. Keep human in control loop to some degree/at times

4. Make automation flexible/adaptive

5. Positive management philosophy about human roles
