Poverty of the Stimulus Without Tears: Language Acquisition (Lisa Pearl)

LISTEN TO THIS EPISODE

Source cover or paper first page: Poverty of the Stimulus Without Tears

Lisa Pearl reviews poverty-of-the-stimulus arguments in the study of language development.

The central question is whether children’s available input can support the knowledge they acquire.

She distinguishes problems caused by missing, noisy, misleading, or genuinely ambiguous evidence.

Formal learning arguments and computational models help assess when the proposed problem occurs.

The review separates evidence for learning constraints from claims about language-specific innate knowledge.
