Abstract: | Domestic chicks selected for high and low locomotor activity in a novel environment have low and high levels of fearfulness, respectively. Using four commonly employed methods of estimating fear, namely emergence, open-field, response to a bell and tonic immobility tests, we found a similar effect in lines of Japanese quail selected for high and low locomotor activity, i.e. the active line appeared the least fearful. The present findings demonstrate that this effect is common to two gallinaceous species and two selection procedures. |
