The term “functional” has been used when diagnosing motor and articulation disabilities in children.“Functional” articulation problems may have underlying etiologies which should be investigated further.

Articulation may be thought of as utterances of speech which are monitored and maintained by adequate systems of feedback which consist of the auditory, tactile, and kinesthetic senses, and which control sensory-motor coordination in the oral cavity.An articulation problem could result from disturbances to any one of these three senses and would be manifested in motor disturbances.

The purpose of this study was to employ a unique method of oral-form discrimination testing in which simultaneous oral and manual manipulation of plastic forms was investigated.It was also the purpose of this study to investigate the oral discrimination ability of boys versus girls, and children of three different age groups.

The results of this investigation were:

1. A different method of oral-form discrimination testing (simultaneous oral-manual manipulation of plastic forms) can be developed so that it: A. retains use of only one sensory modality. B. results in errors comparable to the familiar Oral-Oral Method of oral-form discrimination testing. C. allows the investigator a choice of methods to suit his/her purposes.

2. There is no difference in the oral discrimination ability (as measured by the two test methods) of girls versus boys.

3. There appears to be an age differential in oral discrimination ability.
