心理学家们对“智力”一词所指的内容有不同理解,根据智能学说智力有如一幅家系图,它的根基是一般智力(也可称“g”因素),在它上面,则是特别类型的能力(譬如:语言能力、数字能力、空间知觉能力、记忆能力、推理能力以及手工操作能力等)。据认为,有的个人和集团较之其它个人与集团,在一般和特别能力方面,具有更强的智力技能。 Psychologists have different understandings of what is meant by the word “intelligence”. According to the theory of intelligence, intelligence is like a pedigree. Its basis is general intelligence (also called “g” factor), and above it is Special types of abilities (eg, language skills, numeracy skills, spatial perception skills, memory skills, reasoning skills, and manual skills). It is believed that some individuals and groups have stronger intellectual skills than others and groups in terms of general and special abilities.
