necessary skills for visually guided reaching
Necessary Skills for Visually-Guided Reaching
  • Perceptual skills
    • Object recognition
    • Figure-ground separation
  • Motor skills
    • Arm and hand coordination
    • Fine-motor coordination and control
  • Visual-motor integration and coordination
    • Visual guidance of the hand
    • Timing of the grasp
the normative sequence of reaching
The Normative Sequence of Reaching
  • 1 – 2 Months
    • Glance at objects when present
    • Begin to fixate objects for 5-10 sec
    • Arms not organized with vision
  • 2 – 3 Months
    • Isolation of components breaks down
    • Focus on objects
    • Beginning of prehensory behavior
    • Raise hand towards object
  • 3 – 4 Months
    • Mutual grasping, 1 or 2 hands
    • Sometimes turn torso towards object
  • 4 – 5 Months
    • Integrated looking and grasping
    • “Top-level” reaching
    • Good grasping of object
reaching for a moving object
Reaching For A Moving Object

The number of reaches at each speed and age, expressed as a proportion of the maximum number of possible reaches (3 per condition).

type of contact with a moving object
Type of Contact With a Moving Object

The type of contact with the object. Proportion of total number of reaches for “grasp,” “touch,” and “miss.”
