Nine small-for-gestational age (SGA) and 10 appropriate-for-gestational age (AGA) fullterm infants were assessed using the Bayley MDI scale at 10 months, and infant-mother interactions observed at 6 months. Relationships among interaction parameters and development were compared with those of earlier interactions and development. At 6 months SGA and AGA mothers behaved similarly in interaction; SGA infants were more passive than AGA infants and demonstrated higher levels of state change. AGA infant vocalising frequencies at 2, 3 and 6 months were negatively related to MDI scores whereas maternal stimulation was positively related. Aspects of early SGA infant activity were negatively related to 10 month development; at 6 months several variables expressing dyadic interaction were negatively related. Ten month MDI scores were lower for the SGA than the AGA group. Socioeconomic status was related to MDI scores for AGA but not SGA infants. The results suggest that AGA and SGA infants behaved differently in interaction and that differential interaction patterns were linked with optimal development. Maternal stimulation and co-ordinated infant signalling in AGA dyads, and infant quietness and maternal activity encouraging quietness in SGA dyads, were patterns in high-scoring subjects. The exploratory nature of the study is noted.
选取9名小于胎龄（SGA）足月儿和10名适于胎龄（AGA）足月儿，在其10个月大时使用贝利智力发育指数（MDI）量表进行评估，并观察其6个月大时婴儿与母亲的互动情况。将互动参数与发育之间的关系，与早期互动和发育的关系进行比较。6个月大时，SGA组和AGA组的母亲在互动中的表现相似；SGA组婴儿比AGA组婴儿更被动，且状态变化水平更高。AGA组婴儿在2个月、3个月和6个月时的发声频率与MDI得分呈负相关，而母亲的刺激则与之呈正相关。早期SGA组婴儿活动的某些方面与10个月时的发育呈负相关；6个月时，几个表示二元互动的变量呈负相关。SGA组婴儿10个月时的MDI得分低于AGA组。社会经济地位与AGA组婴儿的MDI得分有关，但与SGA组婴儿无关。结果表明，AGA组和SGA组婴儿在互动中的行为表现不同，不同的互动模式与最佳发育有关。AGA组二元组中母亲的刺激和婴儿协调的信号传递，以及SGA组二元组中婴儿的安静和母亲鼓励安静的行为，是高分受试者的模式。本研究具有探索性质。
