Spatial representation and thinking have evolutionary importance for any mobile organism.
In addition, they help reasoning in domains that are not obviously spatial, for example …

The ability to mentally represent the movement of hidden objects (ie, invisible displacement)
is of theoretical importance due to its generally accepted status as an indicator of the …

This chapter is a selective review of spatial development, stressing several points. First, we
suggest that spatial development can be usefully considered to have two strands:(a) the …

In this study, 6‐month‐olds' ability to mentally rotate objects was investigated using the
violation‐of‐expectation paradigm. Forty infants watched an asymmetric object being moved …

Mental rotation involves transforming a mental image of an object so as to accurately predict
how the object would look if it were rotated in space. This study examined mental rotation in …

Object permanence is a component of physical cognition and refers to the knowledge that
an object still exists when out of sight or displaced. Many animal species develop object …

The fields of developmental and comparative psychology both seek to illuminate the roots of
adult cognitive systems. Developmental studies target the emergence of adult cognitive …

Great apes are able to request objects from humans by pointing. It is unclear, however,
whether this is an associated response to a certain set of cues (eg the presence and …

Contemporary comparative cognition has a large repertoire of animal models and methods,
with concurrent theoretical advances that are providing initial answers to crucial questions …

The ability to represent hidden objects plays an important role in the survival of many
species. In order to provide an inclusive synopsis of the current benchmark tasks used to test …
