Problem: A different cognitive capacity is the perception of sequencing which is critical in syntactic structure. Jensen et al. (2019) designed an experiment on sequence perception which also showed that it was not simply rewards that governed the monkeys ability to make cognitive inferences like, if a is to the left of b, and b is to the left of c, then it follows that a is to the left of c. Illustrative of trends in the field, Jensen's senior coauthor, Herbert Terrace, famously lead a project in the 1970s attempting to teach language to a chimpanzee subject whom they playfully named, Nim Chimpsky (Terrace et al., 1979). Clearly in the intervening decades Terrace shifted his focus from animal communication to animal cognition as a central means of insight into the evolution of human language. Studies about animal communication like, those done with Nim Chimpsky, clearly showed that chimpanzees are not good vocal mimics, but the fact that they were able to learn hundreds of signs, indicated that they are excellent gestural mimics. Mirror neurons are nerve cells that fire either when you do a motion, or you see someone else perform a motion you recognize. Arbib (2017) points out that the presence of mirror neurons in primates and their ability to learn, mimic, and refine hand motions could represent an important evolutionary link toward language with our closest genetic relatives. Going even further, in a review Tecumseh Fitch (2017) argues using evidence from various animal behavior studies, that great ape cognitive sophistication reaches a level where it supplies all the elements.
