Visual imagery is our ability to ‘see with the mind’s eye’ and the
vividness with which people report being able to imagine varies
substantially with some people reporting incredibly strong lifelike imagery
while others report very weak imagery. A recently identified group
(congenital aphantasia) report not experiencing any visual imagery at all.
Due to its inherently private nature, one of the main hurdles to overcome
in visual imagery research is objectively and reliably measuring individual
differences in the ability to imagine. In my presentation I will report on
some behavioural (binocular rivalry) and physiological (skin conductance
and pupillometry) measures that can be used to index visual imagery
strength in the general population, as well as in congenital aphantasia. I
will then also discuss how cortical excitability might drive the individual
differences in visual imagery strength, reporting on our recent findings
that show that a less excitable visual cortex produces the strongest visual
imagery. Lastly, I will talk about how individual differences in visual
imagery ability may influence a range of cognitive functions, specifically
assessing the relationship between visual imagery and visual memory, visual
attention and mental rotation, both in the general population and
congenital aphantasia.
