Yang, Jiale; Kanazawa, So; Yamaguchi, Masami K.; Kuriki, Ichiro – Journal of Experimental Child Psychology, 2013
The current study examined color constancy in infants using a familiarization paradigm. We first obtained isoluminance in each infant as defined by the minimum motion paradigm and used these data to control the luminance of stimuli in the main experiments. In the familiarization phase of the main experiment, two identical smiling face patterns…

Otsuka, Yumiko; Konishi, Yukuo; Kanazawa, So; Yamaguchi, Masami K.; Abdi, Herve; O'Toole, Alice J. – Child Development, 2009
This study compared 3- to 4-month-olds' recognition of previously unfamiliar faces learned in a moving or a static condition. Infants in the moving condition showed successful recognition with only 30 s familiarization, even when different images of a face were used in the familiarization and test phase (Experiment 1). In contrast, infants in the…

Otsuka, Yumiko; Konishi, Yukuo; Kanazawa, So; Yamaguchi, Masami K. – Journal of Experimental Psychology: Human Perception and Performance, 2009
Previous psychophysical studies have shown that the adult human visual system makes use of form information such as occlusion to determine whether to integrate or segregate local motion signals (J. McDermott, Y. Weiss, & E. H. Adelson, 2001). Using the displays developed by McDermott et al., these experiments examined whether occlusion and amodal…

Okamura, Hiromi; Kanazawa, So; Yamaguchi, Masami K. – Infant and Child Development, 2007
The perception of colour in an embedded field is affected by the surround colour. This phenomenon is known as chromatic induction. In the present study we investigated whether the colour perception by infants aged 5-7 months could be affected by the surround colour. In Experiments 1 and 2 each stimulus was composed of an array of six squares in…
