Abstract

The d2 Test of Attention (d2) is widely used for assessing sustained attention and we aimed at verifying whether working memory may be a secondary construct measured by d2. 70 university students were assessed using d2 conventional paper-and-pencil and computational version. The experimental group and control group performed the task with or without target key, respectively. Continuous Performance Test (CPT) and N-back (1 and 2-back) tasks were used to measure sustained attention and working memory, respectively. Computational d2 performance was predicted by CPT (p < .05; R² = .15) in the experimental group, and it was predicted by 2-back (p < .05; R² = .28) in the control group. Conventional d2 performance was predicted by 2-back for both control group (p = .01; R² = .20) and experimental group (p = .02, R² = .17). Results suggest the involvement of working memory in d2, possibly a secondary construct assessed by this instrument.

d2 注意力测试只评估持续注意吗？涉及工作记忆过程的证据。

d2 注意力测验（d2）被广泛用于评估持续注意，我们的目的是验证工作记忆是否可能是 d2 测定的二级结构。我们使用传统纸笔版和计算版 d2 对 70 名大学生进行了评估。实验组和对照组分别在有目标键或无目标键的情况下完成任务。持续表现测试（CPT）和N-back（1和2-back）任务分别用于测量持续注意力和工作记忆。在实验组中，计算 d2 成绩是由 CPT 预测的（p < .05；R2 = .15），而在对照组中，计算 d2 成绩是由 2-back 预测的（p < .05；R2 = .28）。对照组（p = .01; R2 = .20）和实验组（p = .02, R2 = .17）的常规 d2 成绩均可通过 2-back 预测。结果表明，工作记忆参与了 d2，这可能是该工具评估的次要结构。
