A Comparison of Encephalization between Odontocete Cetaceans and Anthropoid Primates
  • L. Marino
  • Medicine, Biology
  • Brain, Behavior and Evolution
  • 6 March 1998
TLDR
Results show that the encephalization level of Homo sapiens is still extraordinary relative to that of nonhuman species, but a subset of delphinid odontocetes are significantly more highly encephalized than the most highlyEncephalized anthropoid primates and narrow the gap in encephalizations between humans and nonhumans substantially.

Convergence of Complex Cognitive Abilities in Cetaceans and Primates
  • L. Marino
  • Medicine, Biology
  • Brain, Behavior and Evolution
  • 19 June 2002
TLDR
Evidence that convergent intelligence has occurred in two distantly related mammalian taxa is provided and these findings have important implications for understanding the generality and specificity of those processes that underlie cognition in different species and the nature of the evolution of intelligence. Expand
Origin and evolution of large brains in toothed whales.
TLDR
It is shown that brain size increased significantly in two critical phases in the evolution of odontocetes, and was accompanied by a decrease in body size in Delphinoidea only by 15 million years ago. Expand
Cetaceans Have Complex Brains for Complex Cognition
TLDR
A group of eminent cetacean researchers respond to headlines charging that dolphins might be "flippin' idiots" by concluding that the large brain of cets evolved to support complex cognitive abilities. Expand
Construct Validity of Animal-Assisted Therapy and Activities: How Important Is the Animal in AAT?
ABSTRACT Animal-assisted therapy and animal-assisted activities involve a nonhuman animal as a key therapeutic agent in some kind of intervention that may range from highly specified, as in AAT, toExpand
Thinking chickens: a review of cognition, emotion, and behavior in the domestic chicken
  • L. Marino
  • Psychology, Medicine
  • Animal Cognition
  • 2 January 2017
TLDR
The overall conclusion is that chickens are just as cognitively, emotionally and socially complex as most other birds and mammals in many areas, and that there is a need for further noninvasive comparative behavioral research with chickens as well as a re-framing of current views about their intelligence. Expand
Cetacean brain evolution: Multiplication generates complexity.
TLDR
Cetaceans possess a unique underlying neocortical organizational scheme that is particularly intriguing in light of the fact that cetacean exhibit cognitive and behavioral complexity at least on a par with the authors' closest phylogenetic relatives, the great apes. Expand
Mental disorder as a Roschian concept: a critique of Wakefield's "harmful dysfunction" analysis.
TLDR
The authors propose that mental disorder is a Roschian concept characterized by instrinsically fuzzy boundaries and that Wakefield's analysis may only prolong scientific debate on a fundamentally nonscientific issue. Expand
Dolphin-Assisted Therapy: More Flawed Data and More Flawed Conclusions
ABSTRACT Dolphin-Assisted Therapy (DAT) is an increasingly popular choice of treatment for illness and developmental disabilities by providing participants with the opportunity to swim or interactExpand
Bubble ring play of bottlenose dolphins (Tursiops truncatus): implications for cognition.
TLDR
The authors supplemented qualitative observations with statistical methods to examine playful bouts of underwater bubble ring production and manipulation in 4 juvenile male captive bottlenose dolphins (Tursiops truncatus). Expand
