Example frames from the recordings of the interaction can be seen in Figure 6. This reveals an asymmetry in the dynamics between the parent and infant movements. In many cases introducing changes into a coding scheme requires re-analyzing the same videos all over again. Dry Room Treatments Collection. Further studies of this issue are necessary to confirm whether this asymmetry decreases with age as the one we observed during the feeding task where the infant was older and the aCRQA parameters suggested a more synchronized interaction. Manual coding of interactions is a time-consuming task, which is a limitation in many projects. You can login by using one of your existing accounts.

An empirical study of the naive Bayes classifier. Then, these coordinates were compared with the central coordinates of the next frame to determine the direction of movement Figure 2B. Here, the recurrence was averaged between the parent and five other randomly selected infants. In this case, the temporal order of the infant time series was shuffled and its recurrence computed with the original parent time series. John Wiley and Sons Inc. Sandra Lee, has shared a new compilation of her best patients. Our analysis is focused on PCI episodes, where the parent and the infant spontaneously oriented face to face while the parent was animating an object.
