18 high risk and 17 low risk kids were recorded wearing the LENA between 12 and 24 months with most recordings made at 12,15, or 18 months, and a few children recorded more than once. These recordings were submitted to LENA's software for initial analysis (including AVA scores, CVC, etc.) and will be interrogated for measures of synchrony and other aspects of conversational behavior. CDI, ADOS-2, Mullens, & Vineland were also administered. The goal was to study how conversational statistics relate to outcome measures as a function of risk status. # TODO turn this into a readme - provide list of files - provide list of columns and info to interpret them # Variables ## Volubility & articulation basics - CVC percentile - AVA percentile ## Conversational statistics ### We used in our previous paper - pitch range similarity paired segments - pitch mean convergence over a conversational block ### Used in previous ASD work - amount/proportion of overlap segments - length of interpersonal pause <-- might be really noisy (see above complaint about dur) - contingency defined as proportion voc followed by other person voc in XX secs -- use Anne's script - *erh we had said "also" response time - but isn't that the same as the interpersonal pause?* ## Outcomes - CDI 18m & 24m - ADOS overall score - Outcome status (ASD, TD, Non-TD) - Mullens at 30m - Vineland at 30m
