In Saffran's experiment, what are transitional probabilities used to measure?

Transitional probabilities are crucial in Saffran's experiment as they specifically measure the likelihood of one sound transitioning to another within a sequence. This concept is fundamental to understanding how infants learn about the structure of language. In the context of the experiment, infants were exposed to streams of sounds where certain sound pairs appeared together more frequently than others. By analyzing the transitional probabilities, researchers could determine how well the infants were able to segment the stream into recognizable units or syllables.

This capability plays a significant role in language acquisition, as it highlights how individuals use statistical regularities in their environment to inform their understanding and processing of language. The higher the transitional probability between sounds, the more likely they are to be perceived as part of the same unit or word by listeners. Hence, this option accurately captures the focus of Saffran's research on auditory processing and language learning.
