wais-iv等尺度的韦氏测量一般智力的Cassel所提出的双因素理论的发展，其复合材料的流体智力。流体能力被认为是生物驱动的，代表了一般的能力，对新的任务和陌生的情况下，而结晶能力代表推理和解决问题相关的特定于任务的知识。wais-iv措施流体智力在演出规模和结晶的言语量表智力。整体的IQ（智商或FSIQ）结合这两个尺度。有许多理论和WAIS测试实施后的发展提出的，包括XXX。Cattell Horn Caroll（CHC）在2000年理论。韦斯和同事（韦斯，2010）挑战的信念，即个人的智力增长和发展代表了一个主要固定的特点，只是轻微影响的性质和质量的环境机会和经验的展开。回顾CHC发现。这些技能固定或因指令或社会因素的可塑性？对口译的影响，作为干预的教育政策，以及社会如何决定成就和成功。
WAIS-IV and other scales developed by Weschler measure 'general intelligence' proposed by Cassel's two-factor theory, which composites fluid and crystallized intelligence. Fluid ability is thought to be biologically driven and represents general ability to reason on novel tasks and unfamiliar contexts, whereas crystallized ability represents reasoning and problem solving related to task-specific knowledge. WAIS-IV measures fluid intelligence on the performance scale and crystallized intelligence on the verbal scale. The overall IQ score (Full-Scale IQ or FSIQ) is based on a combination of these two scales. There were many theories proposed after the development and implementation of WAIS tests, including xxx. Cattell-Horn-Caroll (CHC) theory in the year 2000. Weiss and colleagues (Weiss, 2010) challenge the belief that the intellectual growth and development of individuals represents the unfolding of a predominantly fixed trait only marginally influenced by the nature and quality of environmental opportunities and experiences. Review with CHC has found.Are all these skills fixed or malleable due to instruction or social factors? The impact on interpretation, the educational policy as intervention and how does the society determine achievement and success.
