本文通过对能力分化与整合现象的考虑，提出了一种适合度指标与人类智力生活史模型之间的潜在综合。认知分化整合努力假说提出，这些影响来自生活史之间的权衡认知整合努力，交配努力与加强积极的多方面的能力;和认知分化努力，与特定能力的培养相关的躯体努力的组成部分。这代表了智力遗传变异的两个基本独立的来源之一;另一个是由一般健身和突变负荷介导的，并与“遗传g”水平的个体差异有关。这两个来源（沿着环境变异的共同来源）联合收割机产生了各种认知表型，其特征是高或低水平的“遗传g”和认知专长或通才的不同组合。该模型的基本假设是生活史速度（K）和g的测量基本上是独立的，这通过对10项报告变量之间相关性的研究进行荟萃分析（ρ = 0.023，ns，n = 2056）得到证明。该模型的影响进行了讨论，在进化，生态和发展的背景下。在讨论中提出了七个关键的预测，如果测试可以提供明确的证据的假设。
This article presents a potential synthesis between the fitness indicator and life history models of human intelligence through consideration of the phenomena of ability differentiation and integration. The cognitive differentiation-integration effort hypothesis proposes that these effects result from a life history tradeoff between cognitive integration effort, a mating effort component associated with strengthening the positive manifold amongst abilities; and cognitive differentiation effort, a somatic effort component associated with the cultivation of specific abilities. This represents one of two largely independent sources of genetic variance in intelligence; the other is mediated by general fitness and mutation load and is associated with individual differences in levels of ‘genetic g‘. These two sources (along with a common source of environmental variance) combine to give rise to a variety of cognitive phenotypes characterized by different combinations of high or low levels of ‘genetic g‘ and cognitive specialism or generalism. Fundamental to this model is the assumption that measures of life history speed (K) and g are essentially independent, which is demonstrated via meta-analysis of 10 studies reporting correlations between the variables (ρ = .023, ns, n = 2056). The implications of the model are discussed in an evolutionary, ecological, and developmental context. Seven key predictions are made in the discussion which if tested could provide definitive evidence for the hypothesis.
