From: Exploiting large language models for diagnosing autism associated language disorders and identifying distinct features

F

Name

Explanation

F1

Echoic repetition

The individual mimics verbatim what has been said by others, including the examiner, or recites phrases from external sources like advertisements or movie scripts, showing a delayed echo response.

F2

Unconventional content

The speech contains peculiarly chosen content or contextually odd phrasing, such as using “unfreshness through household” for lack of novelty, “mideast” instead of “midwest” for U.S. states, or describing entry into a building as “through various apertures”.

F3

Pronoun displacement

Incorrectly substitutes personal pronouns, using “you” in place of “I”, or refers to themselves in the third person, either by pronouns like ’he/she’ or by their own name.

F4

Incongruous humor timing

Incorporates humorous or comedic expressions inappropriately during discussions meant to be serious, showing a misalignment between the content’s emotional tone and the context.

F5

Formalistic language use

Employs an overly formal or archaic language style that seems lifted from written texts, legal documents, or old literature, rather than engaging in conversational speech. Examples include elaborate ways of expressing simple ideas or feelings.

F6

Superfluous phrase attachment

Attaches redundant phrases or filler expressions to their speech without contributing any substantive meaning or context, such as “you know what I mean” or “as they say,” indicating a habit rather than intentional emphasis.

F7

Excessive social phrasing

Utilizes conventional social expressions excessively or inappropriately, responding with phrases like ’oh, thank you’ in contexts where it does not fit or preempting social gestures not yet performed by the interlocutor.

F8

Monotone social expression

Reiterates social phrases with an unchanged, monotonous intonation, indicating a lack of genuine emotional engagement or variability in social interactions.

F9

Stereotyped media quoting

Quotes lines from commercials, movies, or TV shows in a highly stereotypical manner, employing a canned intonation that mimics the original source closely, suggesting a reliance on external media for verbal expressions.

F10

Clichéd verbal substitutions

Resorts to well-known sayings or clichés in lieu of engaging in direct conversational responses, using phrases like ’circle of life’ or ’ready to roll’ as stand-ins for more personalized communication.
