Abstract: Gibbs and Ng conducted a series of experimental studies using one-tri-al taste-avoidance task in one day-old chicks and proposed a new hypo-thesis of three-stage model of memory formation, which is short-termmemory (STM), intermediate-term memory (ITM)and long-term memory(LTM). Since 1986 Patterson et al., have replicated and extended someof the key findings of Gibbs and Ng, But Roberts expressed doubts towardthis model. Now debate on both sides is still continuing. Recently, weundertook an experiment to study the stages of memory formation in nor-mal one-day-old chicks. Our results were similar to those of Gibbs andNg. Using chicks as a model for thestudy of learning and memory is ofgreat value and it has many advantages. This method is worthy of note.
