This study sought to deconstruct gambling task (GT) performance among HIV+ individuals (N = 143) and is intended to capture other cognitive features of task performance (i.e., problem solving and strategy preference). Consistent with our hypotheses, cluster analysis identified three GT groups: a safe/advantageous (AS) strategy group, a risky/disadvantageous (RS) strategy group, and a novel third group who failed to develop a strategy (NS). The NS group performed worst on global neuropsychological performance, processing speed, and executive function. Our results support a novel measure of GT task performance and suggest that failure to develop/implement a strategy reflects cognitive dysfunction.
这项研究旨在解构 HIV+ 个体(N=143)的赌博任务(GT)表现,并旨在捕捉任务表现的其他认知特征(即解决问题和策略偏好)。与我们的假设一致,聚类分析确定了三个 GT 组:安全/有利(AS)策略组、风险/不利(RS)策略组和一个未能制定策略的新颖第三组(NS)。NS 组在全球神经心理学表现、处理速度和执行功能方面表现最差。我们的结果支持 GT 任务表现的一种新的衡量标准,并表明未能制定/实施策略反映了认知功能障碍。
