Figure 4

Development of lateral spatial interactions in an individual macaque tested longitudinally (from 13 to 60 weeks). Axes and labels are as in Figure 3. For this animal, suppressive interactions were present at the youngest test age (panel A), although the more typical adult pattern of suppression by only nearby flankers first appeared at the 40 weeks test age (panel C). The adult pattern of facilitation was not apparent until 60 weeks (panel D). Note also, threshold elevation at all flank distances relative to the unflanked threshold at the youngest test ages (panels A & B). The data shown in panels A and B were collected at a viewing distance of 40cm while those in panels C and D were collected at 125cm.
