动态技能理论(DST)认为，当其他技能刚开始发展时，领域内的技能可能会促进或抑制其他技能，导致一项技能的快速增长与另一项技能的倒退同时发生。我通过考察两种言语前表征技能的发展来检验这一前提：手动指点和象征性手势。指点是一种强有力的早期交流手势，表明婴儿意识到他人的注意，但随着他们在直接环境之外的成长，代表婴儿概念技能的能力受到限制。象征性手势是更具体但不太灵活的表征工具。这两种技能都能预测语言，但还没有研究指出这两种技能对彼此的影响。我在一个手势丰富的环境中观察了10个婴儿在8个月的时间里的手势行为，以测试每种技能对另一种技能的影响。支持DST的结果显示，早期的指向预测了更早的符号手势，而符号手势确实抑制了指向频率。
Dynamic Skills Theory (DST) posits that skills within domains may promote or suppress other skills as they first develop, resulting in spurts of growth in one skill concurrently with regression in another. I test this premise by examining development of two preverbal representational skills: manual pointing and symbolic gestures. Pointing is a robust early communicative gesture, indicating infants’ awareness of others’ attention, but limited in ability to represent infants’ conceptual repertoires as they grow beyond the immediate environment. Symbolic gestures are more specific but less flexible representational tools. Both skills predict language, yet no study has addressed the effects of these skills on each other. I observed the gesturing behavior of 10 infants over 8 months in a gesture-rich environment to test the effects of each skill on the other. Supporting DST, results show early pointing predicted earlier, but not more, symbolic gesturing, while symbolic gesturing did suppress pointing frequency.
