Here’s another example published just last month, Jan 2015. Turns out the
memory systems in the visual pathways of monkeys are closer than we thought to those of humans. They are not exactly the same, but they are not significant different in a qualitative way.

Abstract:
Two adult rhesus ***monkeys were trained to detect which item in an array of memory items had changed using the same stimuli, viewing times, and delays as used with humans. Although the monkeys were extensively trained, they were less accurate than humans with the same array sizes (2, 4, & 6 items), with both stimulus types (colored squares, clip art), and showed calculated memory capacities of about 1 item (or less). ***Nevertheless, the memory results from both monkeys and humans for both stimulus types were well characterized by the inverse power-law of display size. This characterization provides a simple and straightforward summary of a fundamental process of visual short-term memory (STM; how VSTM declines with memory load) that emphasizes species similarities based upon similar functional relationships. By more closely matching monkey testing parameters to those of humans, the similar functional relationships strengthen the evidence suggesting similar processes underlying monkey and human VSTM.

So yeah go ahead and
say animals can’t think of you want, but don’t expect me to believe it. A few decades ago, behaviorism tried to downplay the significance and even relevance of human thought, and we’re just now climbing out of those “dark ages.” Now as our knowledge base, research staffs, and technology advance, so can our understanding of our world. Sticking to old clichés has its place, especially when we really don’t know any better.
