Asian elephants, Elephus maximus, have the greatest volume of cerebral cortex available for cognitive processing of all extant terrestrial animal species. A manifestation of cognitive behaviour is tool use and tool manufacture. Fly switching with branches is a type of tool use previously shown in captive Asian elephants to be effective in repelling flies and to vary in frequency with the intensity of flies. In the first part of the present study we report on observations of one juvenile and 33… 
Self-recognition in the Asian elephant and future directions for cognitive research with elephants in zoological settings.
TLDR
The opportunity and rationale for conducting cognitive research on elephants in zoological facilities are discussed, and some of the recent developments in the field of elephant cognition are reviewed, including the recent study on mirror self-recognition in E. maximus.
Tuskedness in African elephants – an anatomical investigation of laterality
TLDR
It is shown that individuals with larger overall tusk pairs had a higher degree of tusk laterality, consistent with the view that the reported asymmetries result from behavioral lateralization, that is, side preferences in tusk use in rooting, stripping bark and during agonist interactions.
Behavioural variability among captive African elephants in the use of the trunk while feeding
TLDR
It is suggested that during their lives elephants develop individual strategies adapted to the manipulated items, which increases their feeding efficiency, and this ability could underlie individual-level strategies.
Large brains and cognition: Where do elephants fit in?
Elephant cognition in primate perspective
On many of the staple measures of comparative psychology, elephants show no obvious differences from other mammals, such as primates: discrimination learning, memory, spontaneous tool use, etc.
Analogous laterality in trunk movements in captive African elephants: A pilot study
TLDR
Laterality in new behaviours in the literature on elephants, such as pinching, gathering or exploration with the trunk, is described, adding evidence for the task complexity theory.
Lateralisation of trunk movements in captive Asian elephants (Elephas maximus)
TLDR
This study investigated laterality of trunk use among captive Asian elephants, quantifying side preference in four different trunk movements: feeding, sand spraying, self-touching, and swinging, and found evidence for significant side preferences in all four movement categories.
Can Asian Elephants Use Water as a Tool in the Floating Object Task
TLDR
The presented floating object task to 12 zoo-housed Asian elephants to determine if they demonstrate innovative problem solving or social learning may bolster support for the convergent cognitive evolution of problem solving in elephants and apes.
Evidence of means–end behavior in Asian elephants (Elephas maximus)
TLDR
It is shown that elephants show means–end behavior when subjected to a Piagetian “support” task, and indicates that such goal-directed behavior occurs in species other than primates.

Cultures in chimpanzees
TLDR
It is found that 39 different behaviour patterns, including tool usage, grooming and courtship behaviours, are customary or habitual in some communities but are absent in others where ecological explanations have been discounted.
The conditions for tool use in primates: implications for the evolution of material culture.
TLDR
It is concluded that strong mutual tolerance was a key factor in the explosive increase in technology among hominids, probably intricately tied to a lifestyle involving food sharing and tool-based processing or the acquisition of large, shareable food packages.
Review : Evolution of the Motor System: Why the Elephant's Trunk Works Like a Human's Hand
TLDR
It is suggested that well-developed mesodiencephalo olivo-cerebellar projections may be an important factor for the differentiation of the large neocortex of the human, primate, elephant, and whale during evolutionary progress.
Evolution of longevity in ungulates and carnivores.
TLDR
Findings for primate species suggest that evolution of longer lifespan, increased metabolic efficiency and increased extra-brain functions represent major characteristics describing the evolutionary success of the mammalian species.

The sensorineural specializations of the trunk tip (finger) of the asian elephant, elephas maximus
TLDR
A unique sensory innervation of this specialized region of the trunk of Asian elephants is described, used for grasping food and tactile and ultimately chemosensory recognition via the vomeronasal organ.
Animal Tool Behavior: The Use and Manufacture of Tools by Animals
TLDR
Through a comprehensive synthesis of the studies produced through 2010, the authors provide an updated and exact definition of tool use, identify new modes of use that have emerged in the literature, examine all forms of tool manufacture, and address common myths about non-human tool use.
