  In recent years a modern conceptualization of trust in human-robot
interaction (HRI) was introduced by Ullman et al.\cite{ullman2018does}. This
new conceptualization of trust suggested that trust between humans and robots
is multidimensional, incorporating both performance aspects (i.e., similar to
the trust in human-automation interaction) and moral aspects (i.e., similar to
the trust in human-human interaction). But how does a robot violating each of
these different aspects of trust affect human trust in a robot? How does trust
in robots change when a robot commits a moral-trust violation compared to a
performance-trust violation? And whether physiological signals have the
potential to be used for assessing gain/loss of each of these two trust aspects
in a human. We aim to design an experiment to study the effects of
performance-trust violation and moral-trust violation separately in a search
and rescue task. We want to see whether two failures of a robot with equal
magnitudes would affect human trust differently if one failure is due to a
performance-trust violation and the other is a moral-trust violation.
