Abstract: In this study, Knauff and Johnson-Laird’s (2002) visual impedance
hypothesis (i.e., mental representations with irrelevant visual detail can
impede reasoning) is applied to the domain of external representations and
diagrammatic reasoning. We show that the use of real objects and augmented
real (AR) objects can control human interpretation and reasoning about
conditionals. As participants made inferences (e.g., an invalid one from “if
P then Q” to “P”), they also moved objects corresponding to premises.
Participants who moved real objects made more invalid inferences than those
who moved AR objects and those who did not manipulate objects (there was no
significant difference between the last two groups). Our results showed that
real objects impeded conditional reasoning, but AR objects did not. These
findings are explained by the fact that real objects may over-specify a
single state that exists, while AR objects suggest multiple possibilities.
