Why are we so good at adapting to "sub-optimal" speech? I argue, in this review paper, that adaptation may be driven by the combined action of dopamine and norepinephrine via prediction error signaling. It's early days with this idea, but I'm excited to have it out there and to keep exploring more!
Stop, drop everything and pick up this new review paper from LABlab member @hannahmech.bsky.social. In it, Hannah argues for considering speech adaptation through the lens of reinforcement learning. Good stuff. link.springer.com/epdf/10.3758...

https://cran.r-project.org/package=SemanticDistance
CRAN: Package SemanticDistance
Cleans and formats language transcripts guided by a series of transformation options (e.g., lemmatize words, omit stopwords, split strings across rows). 'SemanticDistance' computes two distinct metrics of cosine semantic distance (experiential and embedding). These values reflect pairwise cosine distance between different elements or chunks of a language sample. 'SemanticDistance' can process monologues (e.g., stories, ordered text), dialogues (e.g., conversation transcripts), word pairs arrayed in columns, and unordered word lists. Users specify options for how they wish to chunk distance calculations. These options include: rolling ngram-to-word distance (window of n-words to each new word), ngram-to-ngram distance (2-word chunk to the next 2-word chunk), pairwise distance between words arrayed in columns, matrix comparisons (i.e., all possible pairwise distances between words in an unordered list), turn-by-turn distance (talker to talker in a dialogue transcript). 'SemanticDistance' includes visualization options for analyzing distances as time series data and simple semantic network dynamics (e.g., clustering, undirected graph network).

Such a fun experience to travel down to Georgia and have our team of talented students show the summit attendees what the @langscistation.bsky.social is all about! It's been a few summers since I've had the pleasure of running studies with the LSS and it was lovely to reprise my role :)
An exciting month for the The LSS crew! A delegation of our team traveled to Milledgeville, Georgia in early July, where they ran studies with attendees at the Sandra Dunagan Deal Center Governor's Summit on Early Language and Literacy & talked about making language science engaging & interactive!

CRAN: Package ConversationAlign
Imports conversation transcripts into R, concatenates them into a single dataframe appending event identifiers, cleans and formats the text, then yokes user-specified psycholinguistic database values to each word. 'ConversationAlign' then computes alignment indices between two interlocutors across each transcript for >40 possible semantic, lexical, and affective dimensions. In addition to alignment, 'ConversationAlign' also produces a table of analytics (e.g., token count, type-token-ratio) in a summary table describing your particular text corpus.

As you listen to a story, the meaning of each word you hear relates to the meaning of prior words. But how? We operationalized semantic distance, and identified brain regions that correspond to this rolling summary measure during naturalistic listening. #neuroscienceoflanguage
Check out our preprint (linked again here: osf.io/preprints/ps...) where we measured neural sensitivity to changes in semantic space while listening to a podcast. Not only do we look at word-to-word but larger chunks too (2-gram, 5-gram, 10-gram) to examine meaning construction at multiple levels.
