A temporary decrement in the strength of the meaning of a word after rapid repetition of that word has been called semantic satiation. Satiation is a general property of nodes in semantic network and so it would be expected that semantic satiation would be found for stimuli other than words. The objective of this research was to examined the occurrence of satiation for the nonlexical stimuli, and to identify the factors that facilitate decisions when a photo is meaningless. In semantic satiation condition, reaction times to a decision based on repeated photos were longer following 30 repetitions than following 3 repetitions, indicating that satiation had occurred. It was found that a relationship between photographs constitutes a significant factor influencing semantic satiation. The dimensions of valence and arousal also played an important roles in semantic decisions when the meaning of photographs was lost.
