Fig. 3: Therapist responsiveness patterns at the level of individual sessions.

Illustration of significant directional associations between patient language and therapist language in four sessions, each representing a unique patient-therapist dyad. Language features are colored by feature group (see Table 2). Edges are colored according to the average partial correlation coefficient. a illustrates an example of one patient-therapist dyad in which there was just one significant association: increases in patient rate of speech, as measured in words per second, were associated with decreases in therapist rate of speech, and vice versa. b shows a patient-therapist dyad in which the patient’s past-oriented speech and rate of speech had opposite effects on the therapist’s rate of speech. c demonstrates a case where decreases in the patient’s rate of speech led to increases in a diverse array of therapist language features, or vice versa. d highlights a patient-therapist dyad with varied significant associations: increased patient use of third-person plural pronouns (‘“They” Pronouns’) drove increased therapist use of third-person plural pronouns (‘“They” Pronouns’), increased use of positive language by the patient (“Positive”) was associated with increased use of checking for understanding phrases by the therapist (“Checking for Understanding”), etc. These are four of the 73 network diagrams produced, one for each session/patient-therapist dyad.
