  1. The influence of emotional and cognitive processes in the definition of speech rate Marco Tonti Università di Bologna

  2. Table of Contents • The Therapeutic Cycle Model (TCM) • Influence of the TCM processes on the Rate of Speech (Main idea) • Definition and extraction of data • Statistical results • Conclusions

  3. Therapeutic Cycle Model • Defines emotional and cognitive dynamics • Based on transcripts • Divides the text in blocks of words • Computes the density of emotional and cognitive words • Abstract words are markers for cognition Mergenthaler (1996)

  4. TCM – Prototypical Cycle Insight • Word frequencies are standardized as Z-scored values

  5. TCM – Example • Word frequencies are standardized as Z-scored values

  6. Table of Contents • The Therapeutic Cycle Model (TCM) • Influence of the TCM processes on the Rate of Speech (Main idea) • Extraction of data • Statistical results • Conclusions

  7. Main idea (TCM and ROS) Insight • An high emotion level causes slowdonws due to hesitations. • An high cognition level causes slowdowns due to intense elaboration. Low ROS is expected to be a marker for the phenomenon of insight.

  8. TCM and ROS (2) • Higher ROS in I quadrant • Average ROS in II and IV quadrants • Lower ROS in III quadrant

  9. Mental Processes • Mental processes as OS processes • Resurces drained by processes in need for them • Physical effects of resource variation • Variation of the speaking rate

  10. Table of Contents • The Therapeutic Cycle Model (TCM) • Influence of the TCM processes on the Rate of Speech (Main idea) • Definition and extraction of data • Statistical results • Conclusions

  11. Defining the ROS • Text-based methods: • Words per second • Characters per second • Acoustical methods • Phones per second • Syllables per second

  12. Aligning recording and transcript The transcript and the recording have been aligned on the basis of small segments lasting roughly 2 s and containing from 1 to 6 words. The ROS has been computed for each segment. The TCM word blocks are composed by grouping the segments.

  13. Analyzed session info • 36 years old female subject (Romina) • In therapy for eating disorders • Psychodynamic therapy, one session per week • Treatment lasted for 8 months This study is based on the 4th session of the terapy.

  14. Table of Contents • The Therapeutic Cycle Model (TCM) • Influence of the TCM processes on the Rate of Speech (Main idea) • Extraction of data • Statistical results • Conclusions

  15. Correlation between TCM and ROS Word block 175 words Spearman -0.58 Significance 0.004 (<0.05)

  16. Other statistics • The ROS value varies much more rapidly than the TCM value. (The time-scale issue) • The available amount of data is small. (Few word blocks for each session)

  17. Disaggregation of word blocks • Each word block is composed by small segments. • The TCM value of each block is inherited by the composing segments. • This procedure allows a fine-grained analysis of the rate of speech.

  18. Inferential statistics • The test has been run on the four groups of segments belonging to the phases Relaxing, Experiencing, Connecting and Reflecting. • The Kruskal-Wallis test showed a significant difference, for blocks of 175 words, in the mean ROS (CPS) of each group: prob>χ2 = 0.0066 (<0.05)

  19. Table of Contents • The Therapeutic Cycle Model (TCM) • Influence of the TCM processes on the Rate of Speech (Main idea) • Extraction of data • Statistical results • Conclusions

  20. Conclusions (1) This pilot study: • Tends to confirm a connection between ROS and TCM. • Defines low ROS as a marker for insight phases. • Is based on values that can be extracted on a purelyacoustical fashion.

  21. Conclusions (2) • Defines a procedure to further the research in this field, and to improve the research on TCM. • Could allow to skip the heavy work of transcribing the sessions.
