In mirror mark tests dolphins twist, posture, and engage in open-mouth and head movements, often repetitive. Because postures and an open mouth are also dolphin social behaviors, we used self-view television as a manipulatable mirror to distinguish between self-examination and social behavior. Two dolphins were exposed to alternating real-time self-view ("mirror mode") and playback of the same to determine if they distinguished between them. The adult male engaged in elaborate open-mouth… 

Self-recognition in pigeons revisited.

P pigeons spontaneously integrated the learned self-directed and mirror-use behavior and displayed self- directed behavior in a mark test, indicating that pigeons display mirror self-recognition after training of suitable ontogenetic contingency.

Behavioral responses of two species of dolphins to novel video footage: An exploration of sex differences.

The data suggest that television may serve as a useful enrichment device for certain individuals and species of cetaceans, as well as a cognitive experimental tool, as long as sex, species, and individual differences are taken into consideration when interpreting results.

Marine Mammals in Front of the Mirror—Body Experiences to Self-Recognition: A Cognitive Ethological Methodology Combined with Phenomenological Questioning

A new dual conceptual framework is introduced that could be a useful tool to understanding complex phenomena like self-recognition and self-consciousness in animals and reports on some major epistemological and methodological pitfalls to these studies.

Capuchin monkeys (Cebus apella) respond to video images of themselves

Although capuchin monkeys showed no signs of explicit self-recognition, their behaviour strongly suggests recognition of the correspondence between kinaesthetic information and external visual effects in species such as humans and great apes.

Characterizing Curiosity-Related Behavior in Bottlenose (Tursiops truncatus) and Roughtoothed (Steno bredanensis) Dolphins

The hypothesis that there would be a wide range of individual differences in dolphins’ reactions to the stimuli, including differences between species and sex, as well as differences in trait ratings by trainers is supported.

Responses to mirror-image stimulation in jungle crows (Corvus macrorhynchos)

Abstract Four jungle crows (Corvus macrorhynchos) were exposed to a mirror placed either vertically or horizontally. The most frequently observed behaviors were pecking at the mirror and wing

Interaction between infants: understanding intersubjectivity and emotional expression

Infants are born able to express their emotions, and they can synchronise their expressions with their mothers' acts. They are coherent psychological beings, well equipped for social life and

What do dolphins (Tursiops truncatus) understand about hidden objects?

Object permanence, the ability to mentally represent and reason about objects that have disappeared from view, is a fundamental cognitive skill that has been extensively studied in human infants and
