To determine whether people with high scores for schizotypal thinking generate more uncommon words in a letter fluency task than people with low scores.
Prospective study.
University psychology department.
Forty healthy, right-handed students.
Students were administered the Magical Ideation (MI) Scale and a 2-minute letter fluency task in which they named as many nouns as possible beginning with "A" or "F," in any order.
Total number of words produced and percentage of unique, rare and common words (as determined by the responses of the whole group); scores on MI scale.
Participants with high scores (above the median) on the MI scale generated as many words as those who had low scores. People in both groups also generated a comparable number of unique words (named by only 1 person) and common words (named by 6 or more people). As hypothesized, people with high scores on the MI scale generated more rare words (named by fewer than 6 people) than those with low scores.
These findings support the view of a disinhibition of semantic network functioning as the neuropsychological basis of creative thought, magical ideation and thought disorder.
确定在字母流畅性任务中，分裂型思维得分高的人是否比得分低的人产生更多不常见的单词。
前瞻性研究。
大学心理学系。
40名健康的右利手学生。
让学生进行神奇观念（MI）量表测试以及一项2分钟的字母流畅性任务，在该任务中他们要尽可能多地说出以“A”或“F”开头的名词，顺序不限。
产生的单词总数以及独特、罕见和常见单词的百分比（由整个小组的回答确定）；MI量表得分。
MI量表得分高（高于中位数）的参与者产生的单词数量与得分低的参与者相同。两组参与者产生的独特单词（仅由1人说出）和常见单词（由6人或更多人说出）数量也相当。正如假设的那样，MI量表得分高的人比得分低的人产生更多罕见单词（由少于6人说出）。
这些发现支持了这样一种观点，即语义网络功能的去抑制是创造性思维、神奇观念和思维障碍的神经心理学基础。
