The purpose of this study was to perform pilot research upon two normal children aged six years (an age midway between complete absence of time conceptualization and maturation of time concepts) in order to chart the characteristic responses within a conditioning paradigm. Previous literature in the field is reviewed for the purpose of providing a rationale for the use of autonomic variables (galvanic skin response and cephalic vasomotor response) and a delay conditioning procedure. Special attention was devoted to development of a testing technique which would overcome fear of the test situation and equipment. Testing procedures was divided into the following phases: (1) habituation, (2) temporal conditioning, and (3) post-conditioning test series. Both subjects displayed a far better ability to inhibit responding, even during extinction, than was anticipated. The possibility of counting behavior was controlled. A discussion of the various test factors concludes that the use of the current equipment and procedure can be expanded into a larger, cross-sectional project to establish normative profiles of temporal discrimination. Test charts of the subjects' responses are included. [Not available in hard copy due to marginal legibility of original document.] (Author/NH)
