Object tracking & interception - Developmental aspects (rapid improvement 3-7 yrs., slow improvement, 7-9 yrs., mature 11-12 yrs.) Development of Body Image • Identification of Body Parts • Understanding the Function of Body Parts • Efficient Utilization of Space • Right-left and Bi-Lateral Discriminations during Movement Function A child from birth through 3 can visually/verbally identify these body parts • Birth • Can watch the hand move • 1 year • Stomach, head , parts of face, limbs, hands, fingers and toes • 3 years • Objects in relation to body planes, e.g., “things are in front, to the back or to the side of ..” Also …. a child at age 3 • Knows the words “right” and “left,” but not that they are on opposite sides of the body A child from 5 through 7 can visually/verbally identify these body parts • 5 years • 6 years • 7 years • Shoulders, elbows, knees; middle and ring fingers • Trunk appears in drawings; thighs, forearms, etc. identified • Wrists, ankles, shins, parts of limbs Left-right identification 5 – 9 years • 5 years • 6 years • 7 years • 8 years • 9 years • Knows right and left are on opposite sides but is unable to tell which is which • Some left-right judgments made accurately • More correct right-left judgments on self and in letters, numbers etc. • Can identify the left-right of others when facing them • Can describe the left-right movements of others while watching them Fine Motor Skill Progressions Note Critical Developmental Skills of Prehension, Grasping and Releasing – Prehension grasping and releasing e.g. tennis ball, pencil, etc. •Effective grasping (9 mos.) •Thumb opposition (9-10 mos.) •Object release (18 mos.) Manipulating a Writing Instrument – Sequence = supination, pronation, dynamic tripod (7 yrs.) –Posture, hand position Continued - Fine Motor Manipulative Behavior • Drawing and writing Stages of Drawing and Writing Stage 1 – Scribbling developing hand-eye coordination (15-20 MOS.) Stage 2 • Development of Diagrams and combinations of diagrams ~ 1-2 yrs. Stage 3 • Combine stage basic geometric figures (spirals, crosses) to more precise figures, e.g., circles, squares, etc. ~ 2 yrs • ~ 2 yrs. Stage 4 – Aggregate stage combines diagrams and figures into combinations (3+) resulting in more complex drawings 3/7 yrs. Stage 5 – Pictorial stage increased precision and complexity ~ 8-9 yrs. Fine motor development – printing and writing patterns • 4 yr. olds may be able to print recognizable letters/numbers • No particular organizational pattern for numbers/letters • 5-6 yrs. = name printing –5 yrs. = ½ - 2” upper case letters –Letters become larger toward end of name –6 yrs. = similar with occasional reversals – may include surname –By 7 letters are ~1/4 inches – lowercase letters may continue to be difficult By 3 rd grade • Single stroke letters easier (I, c, l) • Horizontal-vertical letters follow (E, T) • Letters with Slants (horizontalvertical) follow – (K, B, Z) • Spacing (9 yrs.)
