Abstract: | The coding system described was originally devised to facilitate the analysis of mother-infant interaction. Our aims were
to provide accurate measures of the duration of different activities, to enable identification of particular actions in order
to carry out sequential analyses, and to allow systematic assessment and improvement of reliability. At the time recording
began, there appeared to be no readily available systems which achieved all of these aims.
The system described here enables coded videotape material to be examined with the assistance of a computer. This is implemented
through two subsystems, those of record and playback. In the playback subsystem the behaviour units identified by a coder
are mapped on to this record. This results in a protocol of behaviour on a highly accurate time base. |
