In the present study we introduce a novel task for the quantitative assessment of both originality and speed of individual associations. This 'BAG' (Bridge-the-Associative-Gap) task was used to investigate the relationships between creativity and paranormal belief. Twelve strong 'believers' and 12 strong 'skeptics' in paranormal phenomena were selected from a large student population (n > 350). Subjects were asked to produce single-word associations to word pairs. In 40 trials the two stimulus words were semantically indirectly related and in 40 other trials the words were semantically unrelated. Separately for these two stimulus types, response commonalities and association latencies were calculated. The main finding was that for unrelated stimuli, believers produced associations that were more original (had a lower frequency of occurrence in the group as a whole) than those of the skeptics. For the interpretation of the result we propose a model of association behavior that captures both 'positive' psychological aspects (i.e., verbal creativity) and 'negative' aspects (susceptibility to unfounded inferences), and outline its relevance for psychiatry. This model suggests that believers adopt a looser response criterion than skeptics when confronted with 'semantic noise'. Such a signal detection view of the presence/absence of judgments for loose semantic relations may help to elucidate the commonalities between creative thinking, paranormal belief and delusional ideation.
在本研究中,我们引入了一项新任务,用于定量评估个体联想的独创性和速度。这个“填补联想空白”(BAG)任务被用于研究创造力与超自然信念之间的关系。从大量学生群体(n>350)中挑选出12名坚定的超自然现象“信徒”和12名坚定的“怀疑论者”。要求受试者对单词对产生单字联想。在40次试验中,两个刺激词在语义上间接相关,在另外40次试验中,这些词在语义上不相关。针对这两种刺激类型分别计算反应共性和联想潜伏期。主要发现是,对于不相关的刺激,“信徒”产生的联想比“怀疑论者”的更具独创性(在整个群体中出现频率更低)。对于结果的解释,我们提出了一个联想行为模型,该模型既捕捉了“积极”的心理方面(即语言创造力),也捕捉了“消极”方面(容易做出无根据的推断),并概述了其与精神病学的相关性。该模型表明,在面对“语义噪声 ”时,“信徒”采用的反应标准比“怀疑论者”更宽松。这种对宽松语义关系的有无判断的信号检测观点可能有助于阐明创造性思维、超自然信念和妄想观念之间的共性。
