Promoting active and successful aging has become crucial to improve quality of life in later adulthood and reduce the impact of cognitive decline. Increasing evidence suggested that the ability to think creatively (e.g., via divergent thinking), similar to cognitive reserve, could represent a beneficial factor against the negative effects of aging. However, there is still little evidence investigating the relationships between divergent thinking, cognitive functions, and cognitive reserve in late adulthood. The present study explored these relationships in a sample of 98 individuals ranging from 61 to 88 years old (mean age: 72.44 ± 6.35). Results showed that visual, but not verbal, divergent thinking was affected by aging. Interestingly, visual divergent thinking performance was predicted by both the cognitive component of crystallized intelligence and cognitive reserve. Only the crystallized component of intelligence was found to mediate the aging effect on visual divergent thinking performance. These results suggest that in later adulthood a potential shift strategy to prior knowledge and semantic components over executive and control components of cognition could underlie a preserved ability to think divergently and, plausibly, creatively. Limitations of the study and implications for successful aging are discussed.
促进积极且成功的老龄化对于提高成年后期的生活质量以及减少认知衰退的影响至关重要。越来越多的证据表明,创造性思维能力(例如,通过发散性思维)与认知储备相似,可能是抵御衰老负面影响的有益因素。然而,仍鲜有证据研究成年后期发散性思维、认知功能和认知储备之间的关系。本研究在98名年龄在61岁至88岁之间(平均年龄:72.44 ± 6.35)的个体样本中探讨了这些关系。结果表明,视觉而非言语发散性思维会受到衰老的影响。有趣的是,视觉发散性思维表现由晶体智力的认知成分和认知储备共同预测。仅发现智力的晶体成分介导了衰老对视觉发散性思维表现的影响。这些结果表明,在成年后期,一种潜在的从认知的执行和控制成分转向先前知识和语义成分的策略,可能是保持发散性思维能力以及合理地创造性思维能力的基础。讨论了该研究的局限性以及对成功老龄化的启示。
