信息加工阶段独立资源的新证据

Some New Evidences of Independent Resources Related to Processing Stages

本研究对与加工阶段有关的独立资源问题进行了研究。实验采用双任务测定方法 ,分别设计了模拟追踪、记忆搜寻和模拟监控等三种主作业 ,以及简单反应时、复杂反应时和手指节奏敲击等三种次作业。这些作业分别动用了与三维度资源理论加工阶段维度的视觉编码、中枢加工和运动输出相对应的三类独立资源。将这六种作业进行匹配 ,共组合成 3× 3种双任务作业情境。实验以次作业绩效为分析指标。结果发现 ,以往对信息加工独立资源的分类过于粗略。另外 ,研究还发现 ,除独立资源外 ,还存在某些通用资源。

The hypothesis of independent resources related to processing stage was experimentally examined in the present study with dual task technique. We designed for the study three primary tasks, including simulating tracking, memory search and simulating monitoring tasks, coupled with other three subsidiary tasks, simple reaction time task, complicated reaction time task and finger rhythmic tapping task. According to the three dimension resource theory, subjects working on these tasks require three independent resources respectively, visual perceptual encoding, central processing and motor responding. The primary tasks and subsidiary tasks were paired to form 3×3 dual task situations. Data analysis was made on the basis of subsidiary task performance. It seems to be that the stage related independent resources need to be precisely further classified. Moreover the present study also revealed that besides the independent resources, there were also resources common in all tasks.
