Closed head injured patients demonstrated greater anticipatory behaviour deficit than cerebral vascular accident patients on a shuttlebox-analog avoidance task, even though these two groups did not differ on escape behaviour and on performance on the individual tests of the Halstead-Reitan Battery and Wechsler scales. Neither clarification of instructions, additional trials, nor enhancement of the warning cue appeared to improve the anticipatory behaviour deficit. It was concluded that anticipatory behaviour deficit should be considered a relatively dense deficit that is not identified by standard instruments. Clinical and practical implications are discussed.
在穿梭箱模拟回避任务中，闭合性颅脑损伤患者比脑血管意外患者表现出更严重的预期行为缺陷，尽管这两组在逃避行为以及Halstead-Reitan成套测验和韦氏智力量表的个别测试表现上并无差异。无论是明确说明指导语、增加试验次数，还是增强警告提示，似乎都无法改善预期行为缺陷。研究得出结论，预期行为缺陷应被视为一种相对严重的缺陷，而标准工具无法识别这一缺陷。本文还讨论了其临床和实际意义。
