Developing Procedures to Facilitate Recording:
In order to have adequate account-of what was observed during observation some procedurrecordings should be followed, either during the observation as soon as after the observation is completed. The error and selectivity of memory caenter into observer's bias, and in turn can distort the information. In order to complete the systematic recording, observer should find a place where sthe can sit and record significant behaviours during observation as well aimmediately after they have taken place. If the observer has the knowledge of short hand then full notes of the observation can be taken down and later on can be transcribed and coded. In projects where video tape-recordings are done then those observation records can become permanent records. In many observational studies mechanical devices or other equipment are used either as an extension of the human senses or as a means of securing permanent records. To enhance physiological observation several mechanical devices are availablefor recording behaviours and events. Voice tremor detectors that are sensitive to stress are used for physiological measurement that are not .easily observed by naked eyes. For visual recording motion picture films, video tapes are suitable media. Observation schedule is a device that allows easy recording during the observation. In the schedule behaviours are listed on the left hand columnThe tallylcheck mark are placed on the right hand columns drawn against the time column. Sometimes, to avoid the long list of behaviour, only the broad categories are listed on an one-page schedule. Each behaviour is coded. The observer has to learn the code. While recording, against each category the behaviour code is entered instead of the tally. For example, against the category of behaviour demonstrates breathing exercise the codactivity like shows inhale pain exhale (e.g. coded as I-P-E, could be entered in tally column).
