This is a dataset with timed norms for 435 object pictures in Mandarin Chinese. These data include naming latency, name agreement, concept agreement, word length, and age of acquisition (AoA) based on children's naming and adult ratings, and several other adult ratings of concept familiarity, subjective word frequency, image agreement, image variability, and visual complexity. The picture stimuli were taken from multiple sources marked by numbers from 1 to 5: Cycowicz et al. (1997) - 1, Bonin et al. (2003) - 2, the PNT (Roach et al., 1996) - 3, Zhang & Yang (2003) -4, and other -5.
