Abstract

Abstract The goal of this study was to investigate if the selection of external information for storage in visual working memory requires control by the central executive when the categorization of targets is guided by instructions. The design was experimental 3 (concurrent task) x 2 (instruction). Forty-eight university students saw eight colored shapes, four of them surrounded by square outlines. Memory was assessed using a recognition task. Targets varied with instructions: targets were presented within squares in the first block and outside squares in the second block. There were three concurrent tasks: no task, articulatory suppression, and backward counting. Performance was measured by hits, false alarms, corrected recognition, and sensitivity (A’), compared using within-subject ANOVAs. Results showed a main effect only for concurrent task, with lower performance in the backward counting condition for all measures. These results suggest that the central executive does not control the perceptual filter, corroborating earlier results.
视觉工作记忆的中央执行与目标选择
摘要本研究的目的是探讨在指令引导下对目标进行分类时,视觉工作记忆中外部信息的选择是否需要中央执行控制。设计为实验3(并发任务)x 2(指令)。48名大学生看到了8个彩色的形状,其中4个被方形轮廓包围。记忆力通过识别任务进行评估。目标随着指令的不同而变化:目标在第一个区域被呈现在方块内,在第二个区域被呈现在方块外。有三个并发任务:无任务、发音抑制和反向计数。性能通过命中、误报、纠正识别和灵敏度(A ')来衡量,并使用受试者内方差分析进行比较。结果表明,仅对并发任务有主要影响,在所有测量条件下,反向计数条件的性能都较低。这些结果表明,中央执行器并不控制感知过滤器,证实了之前的结果。
