This thesis was concerned with the effects of US intensity
(electric shock) upon the development of the conditioned cardiac response,
and upon the differential conditioning of this response. Four groups of
seven dogs each were trained under four intensities of shock while
paralyzed by d-tubocurarine chloride. The results of simple conditioning
indicated no significant conditioning in the groups receiving one and
two ma. shock. The groups receiving four and eight ma. shock showed
significant conditioning, but there was no difference between them. The
results of differential conditioning were difficult to interpret. There
was no significant difference in degree of discrimination between the
two groups which did condition; in view of the failure to obtain
conditioning in the one and two ma. groups it was unreasonable to compare
them with the other two groups for "degree of discrimination”. / Thesis / Master of Arts (MA)
