Ilse Harms @ilseharms

Hi! I am Ilse Harms, the author of this PhD thesis. The #AimOfMyThesis

is to uncover what people see, and what they don’t see in familiar traffic environments; and provide insight into the cognitive processes involved. This thread provides a quick overview of my research.

#Valorisation #TrafficPsychology

#1 Ilse Harms @ilseharms

#ResearchMethod

1 systematic literature review on effects of route familiarity on cognition and behaviour 3 simulator studies on perception

and driver response to directional signs along a familiar route 1 observation study on

pedestrians’ obstacle avoidance and perception (route familiarity 0-100%)

Our #SystematicLiteratureReview

showed that route familiarity was typically found to reduce the amount of cognitive control used to process the immediate environment and to increase mind wandering, compared...

...to unfamiliar situations. This study has been submitted.

#PrismaMethod

In #Experiment1, in a driving simulator, we found that not all drivers are equally able to comply with variable speed limits on familiar roads...

#4

Only 41.7% were aware the speed limit had increased …based on chance, 93.8% was expected. This study has been published in Transportation Research Part F.

#ChangeDetection

With #Experiment2, we tried to improve drivers’ detection of changes in electronic speed limits. However, flashing lights reduced detection, and neither could drivers having correct expectations prevent detection failure...

...This study has been published in Applied Ergonomics. #ChangeDetection

In #Experiment3 a variable message sign repeatedly exposed drivers to adverts prior to displaying a detour instruction. While all complied, 31% failed to recall the instruction. Conscious attention might not be a prerequisite for compliance with road signs.

This study has been published in Transportation Research Part F.

#Automaticity

For #Experiment4 we placed a signboard on a pavement in the city centre of Utrecht. All pedestrians avoided the signboard, though 53.8% was unaware that they had walked around it. Walking on #autopilot was very common, regardless of route familiarity.

This study has been published in Frontiers in Psychology.

#WalkingWithoutAwareness

#Conclusion (1/2)

People get used to familiar traffic environments so much that they don’t have to think about walking or driving with much conscious focus. They can act without thinking about it, so they don’t always even remember what they’ve done.

#Conclusion (2/2)

Remarkably, despite the apparent lack of full or even partial awareness, information – including information that has changed in an otherwise familiar environment – may still guide behaviour.

I defended this PhD thesis on April 23, 2020, at the University of Groningen,...

This is not the end of the journey. Merely a new beginning. Thank you for your attention.
