The Roman high-avoidance (RHA) and low-avoidance (RLA) strains of rats were tested and compared with Maudsley reactive (MR) and non-reactive (MNR) strains to assess the relative contributions of emotionality and conditionability to differences between the two Roman strains. The RHA learned significantly faster in active avoidance, but slightly slower in passive avoidance, significantly faster in acquisition of an active approach task, but slighty slower in extinction of active approach tasks despite extensive adaptation and gentling. The RHA showed more 'rearing', more activity in the open field and more variety-seeking. Crossing with MNR showed the RHA less reactive in the open field. Results show RLA equivocal in conditionability, more emotional, and perhaps less active.
对罗马高回避型（RHA）和低回避型（RLA）大鼠品系进行了测试，并与莫兹利反应型（MR）和非反应型（MNR）品系进行比较，以评估情绪性和条件性对两个罗马品系之间差异的相对贡献。RHA在主动回避中学习明显更快，但在被动回避中略慢，在主动接近任务的习得中明显更快，但在主动接近任务的消退中尽管经过广泛适应和驯化仍略慢。RHA表现出更多的“直立”行为、在旷场中有更多活动以及更多的寻求多样化行为。与MNR杂交显示RHA在旷场中反应性较低。结果表明RLA在条件性方面模棱两可，情绪性更强，且可能活跃度较低。
