Abstract
Speed accuracy trade-offs are commonly seen in learning. These trade-offs may be related to other behavioral traits such as personality. I investigated the relationship between speed accuracy trade-offs and the bold-shy continuum. I tested zebrafish of bold and shy strains in a conditioned place preference task (CPP) and a 2 choice task. In the CPP task the bold fish learned significantly faster than the shy fish and there were no differences in the total change in behavior between strain. There was no correlation between speed and strength of learning in the CPP. In the 2 choice task there is no clear evidence of learning. Bold fish make significantly more choices than shy fish but by the last session there is no difference between the strains. In the 2 choice task there is no significant relationship between decision time and accuracy. There are no significant differences across the 2 choice and CPP task except that there is a difference between treatment and controls in the CPP task and not in the 2 choice task. This study supports that bold fish tend to be faster learners and suggests that the factors that cause the faster learning do not also cause a greater strength of learning.
