概括

认知表现的个体内变化 (IIV) 可能会检测出微妙的问题,但它与前足球运动员的头部损伤史没有直接相关. 目标IIV的措施补充了主观的认知问题.

科学领域:

神经科学是一个神经科学.
运动医学运动医学
认知心理学认知心理学

背景情况:

接触式运动运动员经常在头部受伤后报告认知症状,但客观的绩效测量显示了可变的关联.
个体内变异性 (IIV) 是表现分散的度量,可能比传统指标更好地反映微妙的认知变化和主观关注.
了解头部损伤史,主观认知和客观表现变化之间的关系对于运动员护理至关重要.

研究的目的:

调查前大学足球运动员认知表现的个体内变化 (IIV),主观认知症状和头部损伤史之间的关联.
为了确定IIV指数是否对头部损伤史 (脑震荡和头部冲击暴露) 敏感.
探索IIV和主观认知投诉之间的关系.

主要方法:

57名前大学足球运动员接受了神经心理测试,并完成了主观认知评估 (Neuro-QoL,BRIEF-A).
头部损伤史通过结构化访谈 (头部冲击暴露估计 - HIEE) 进行评估.
计算了三个IIV指数:记忆IIV,反应时间/处理速度IIV (RT/PS-IIV) 和注意力/执行功能IIV. 分析使用了一般的线性模型.

主要成果:

脑震荡和头部冲击暴露的病史与认知分散 (IIV指数) 并没有显著相关.
较差的一般主观认知与更高的RT/PS-IIV相关.
较差的元认知功能 (BRIEF-A) 与更大的记忆-IIV有关,独立于心理困扰和睡眠质量.

结论:

认知分散 (IIV) 作为一个有价值的客观措施,补充主观认知报告.
IIV可能在临床上有意义,用于识别通过平均绩效测量错过的微妙认知困难.
头部损伤史和认知分散之间的直接联系似乎是间接的,如果存在的话.

Cognitivism

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...
