Reports on four experiments on pattern perception in four-month-old infants. The first experiment examined preference for patterns varying in structure; the second examined encoding patterns from different subset sizes; and the last two experiments examined changes in the size, position, and orientation of the habituation pattern. (HOD)

Tests infants' dual-process performance (a process mediating response decrements called habituation and a state-dependent process mediating response increments called sensitization) on visual habituation-dishabituation tasks. (HOD)

Examines whether young children, aged four to nine years old, are satisfied with their own method of drawing a familiar object, or whether they would ideally like to draw in a more advanced way but are hampered by production differences from achieving this aim. (HOD)
