Some Non-Human Languages Of Thought, Nicolas J. Porot
Some Non-Human Languages Of Thought, Nicolas J. Porot
Dissertations, Theses, and Capstone Projects
What might we learn if we take seriously the possibility of non-human Languages of Thought (LoT)? A LoT is a combinatorial set of mental representations. And, since mental representations and rules of combination vary in kind, there are many possible LoTs. Simple LoTs might lack familiar features of the putative human LoT, such as object representations, recursively defined rules of combination, sentential connectives, or predicate-argument structure. The most familiar arguments for the existence of LoTs, such as those from productivity, systematicity, concept learning, and perceptual computation, all fail when applied to non-human animals. But recent empirical evidence motivates attributing LoTs …

Stabilizing Forces In Acoustic Cultural Evolution: Comparing Humans And Birds, Daniel C. Mann
Dissertations, Theses, and Capstone Projects
Learned acoustic communication systems, like birdsong and spoken human language, can be described from two seemingly contradictory perspectives. On one hand, learned acoustic communication systems can be remarkably consistent. Substantive and descriptive generalizations can be made which hold for a majority of populations within a species. On the other hand, learned acoustic communication systems are often highly variable. The degree of variation is often so great that few, if any, substantive generalizations hold for all populations in a species.
Within my dissertation, I explore the interplay of variation and uniformity in three vocal learning species: budgerigars (Melopsittacus undulatus), …
