In order to detect the CR in the associative learning group it would be necessary to include CS-alone trials i. An important methodological objection to using CS-alone test trials is that in the paired arrangement these CS-alone test trials constitute a change from paired CS-US trials in a way that condicionamiento aversivo not reflected in the unpaired control condition.
The greater responding to the CS-alone test trials in the paired experimental condition may be due to reinstatement of the orienting response rather than "true" conditioning.

In the present research, the use of a brief CS-US interval with presummed overlapping conditioned and unconditioned responses precludes direct assesment of the CR.
For these reasons, acquisition of the CR was not measured but, was simply assumed to condicionamiento aversivo normally across the 20 CS-US trials.
Dependent Variable SCR was defined as the maximum deflection occurring 1 - 4 s after US onset and was measured in micro-mhos.
The unconditioned SCRs obtained in the acquisition phase were only considered in the later analysis. Results Prior to other types of analysis, the values of the amplitude of the first UR of both groups were compared, to determine whether the two groups were homogeneous in their condicionamiento aversivo reactivity.
For reasons discussed by Venables and ChristieSCR amplitude was logarhithmically transformed to normalize the distributions prior to analysis. Previously, to avoid a value of 0 log, as well as the log of amplitudes lower than 1 micromho which would be negative1 is conventionally added to all SCRs amplitude scores.
These amplitude data were then range corrected by dividing each condicionamiento aversivo by the maximum response for each subject Lykken, Condicionamiento aversivo obtained values respresent the electrodermal change in relation to the maximum value of this subject, allowing us to compare the electrodermal values across subjects, independent of their initial reactivity to the US.
Condicionamiento aversivo obtained values ranged between 0 and 1. In order to avoid operating with such small values, the resulting values were multiplied by The factors included in the analysis were learning associative vs. Because the sphericity assumption of repeated measurement ANOVAs is likely to be violated by the present type of data, Greenhouse-Geisser probability levels were used when testing effects involving the trials factor Kirk, SCR data from the associative and non-associative groups was condicionamiento aversivo to a 2 x 20 groups x trials ANOVA with repeated measures on the trials.

A significant effect of the learning factor on the amplitude of the unconditioned SCRs was not found: The effect of the trials was highly significant: The interaction of the learning factor with the trials also turned out to be significant: Discussion Contrary to what was expected, no significant differences appear in the amplitude of the SCR between the associative and non-associative learning groups.
Two interrelated reasons appear to explain this result: The second reason is the different temporal pattern exhibited by the amplitude of the SCRs in both groups, which condicionamiento aversivo a compensation of the initial values with the final values, producing nonsignificant differences between the values of both groups.
This effect appears in the two groups, which could be interpreted as the result of a non-associative condicionamiento aversivo of habituation to the UR.
However, the purpose of this work was to find out whether the process of classical condicionamiento aversivo affected the magnitude of the UR.
