海员的深度知觉研究

目的 对海员的深度知觉进行测评，为制定海员选拔标准提供依据。方法 采用深度知觉测试仪对245名海员和87名航海专业学员的深度知觉进行测试。结果 深度知觉对于海员具有很好的鉴别力：不同年龄、工龄、海龄组之间海员深度知觉差异不显著；不同职务、来源和文化程度的海员深度知觉差异不显著；在职海员的深度知觉好于航海专业学员。结论 海员的深度知觉是一稳定的认知能力指标，作为海员的选拔指标是合适的，对于在职海员与学员的评价应有不同要求。

Study of seamen distance perception

Objective To examine distance perception in seaman for the establishment of seaman selection criteria. Methods Distance perception was examined in 245 seamen and 87 seafearing students by distance perception test instrument. Results Distance perception in seaman of different age, work age and sailing age did not exhibit significant different ; distance perception in seaman of different headship, source and education did not exhibit significant different; distance perception in seamen was better than in seafaring students. Conclusions Distance perception is a steady item of seaman perceptibility,which fits to be one of the seaman selection criteria. Different criteria should be used to evaluate seaman and seafearing students.
