行为学研究表明归类过程中的反应具有认知风格上的不同,但未有研究明确探讨归类过程的神经活动是否也受认知风格的影响。本研究通过双重认知风格分型任务筛选出分析型和整体型被试,以探讨归类过程中二者之间是否表现出神经活动的差异。实验任务要求被试从两个待选物中选出与目标物属于同一类别的一个。同时,采用f MRI技术扫描并记录他们完成任务时的BOLD信号。结果发现,与基线任务相比,整体型和分析型个体均激活了额-枕网络的一些脑区,包括额下回、楔前叶、枕中回等,表明不同认知风格个体在任务中可能共享与工作记忆等相关的脑区。另外,与分析型个体相比,整体型个体在右额下回、右旁海马回呈现更广泛的特异性激活,提示,认知风格可以影响归类过程中的脑活动,而整体型个体大脑右半球更强烈的活动表明这一类型认知风格个体在归类时更依赖于远距离的语义联结。
Behavioral studies indicate that responses in the categorization process have cognitive style differences, but no studies have explicitly explored whether neural activity in the categorization process is also influenced by cognitive styles. In this study, the dual cognitive style sub-type task screening analysis of the overall and type of subjects to explore whether the classification process shows the difference between the neural activity. The experimental task required participants to select one of the two candidates in the same category as the target. At the same time, f MRI was used to scan and record the BOLD signal when they completed their task. The results showed that, compared with the baseline task, both monosomic and analytic individuals activated some brain regions of the frontal-occipital network, including the inferior frontal gyrus, the anterior wedge leaf, and the middle occipital gyrus, suggesting that individuals with different cognitive styles It is possible to share brain areas related to working memory. In addition, compared with the analytic individuals, the monolith showed more extensive specific activation in the right inferior gyrus and the right parahippocampal gyrus, suggesting that the cognitive style may affect the brain activity in the categorization process, whereas the monolithic individual brain The more intense activity in the right hemisphere indicates that individuals of this type of cognition rely more on distant semantic links when categorizing.
