Abstract

The purpose of the study was to evaluate differences in sign tracking behavior between Sprague Dawley and Long Evans lab rats. Sign tracking ultimately reflects the degree of impulsivity often modeled in addiction related research. Data collection for sign tracking included three types of data, total number of signtracking behaviors observed, latency scores for sign tracking behaviors, and sign tracking probability scores. Sign tracking latency times and probability scores displayed statistically significant results when comparing the two strains. However, the data regarding the total number of sign tracking interactions with the conditioned stimulus did not come back as statistically significant. The contrast between strains may have different applications in sign tracking research situations.

Sign Tracking Behavior in Long Evans and Sprague-Dawley Rats

The purpose of the study was to evaluate differences in sign tracking behavior between Sprague Dawley and Long Evans lab rats. Sign tracking ultimately reflects the degree of impulsivity often modeled in addiction related research. Data collection for sign tracking included three types of data, total number of signtracking behaviors observed, latency scores for sign tracking behaviors, and sign tracking probability scores. Sign tracking latency times and probability scores displayed statistically significant results when comparing the two strains. However, the data regarding the total number of sign tracking interactions with the conditioned stimulus did not come back as statistically significant.
