Passage

Experimental personality research was extremely popular after 1950 for about three to four decades. In experimental personality research, one of the major focuses is to study how the effect of experimentally manipulated independent variable is moderated by personality variable/s. In one of such study, the researcher wanted to study whether the effect of interpolated learning (A) is moderated by Anxiety (B). The researcher hypothesized that the interpolated learning would adversely affect the recall of original learning, more in high anxious subjects than low anxious subjects. Using a standardized Anxiety scale, from an initial pool of two hundred subjects, fifty high and fifty low anxious subjects were obtained.

Both, high as well as low anxious groups were further divided into two groups-Experimental group and Control group. The experimental groups first learned List A of CVC trigrams then learned another List B of CVC trigrams with similar association values, and then tested for Recall (A). The subjects in control groups learned List A. then they received the cancellation task for the specific period (equal to the average time, taken by the corresponding experimental group to learn List B). The subjects were then tested for the Recall of (A). GroupWise means and standard deviations for recall scores were obtained.

The standard deviations were found comparable across the groups. Treating recall

Scores as the dependent variable, the appropriate ANOVA was carried out. The main effect of A was found significant at 0.05 levels. Similarly, the F-ratio, defined as MSA×BMSE was found statistically significant at 0.01 level.
