Study Notes

Child Development: Abnormal, Typical, and Patterns

Abnormal development types include learning difficulties, language disorders, cognitive delays, autism spectrum disorders, attention deficit disorder, stuttering, and Tourette’s syndrome.
Typical physical development follows cephalocaudal (top-down) and proximodistal (centre-outwards) patterns; gross motor skills develop before fine motor skills.
Cephalocaudal development: head and brain develop first; head-body ratio changes from 50% in the fetus to 6% in adulthood.
Proximodistal development: trunk control precedes limb and finger control.
Child development assessed through gross and fine motor skills, cognitive, perceptual, and social abilities; developmental milestones identify delays.
Screening tests like the Bayley scales evaluate development from infant to toddler age (1 to 42 months), comparing strengths and weaknesses.

Common Facets of Child Development

Development spans multiple areas: physical (body growth), social (interaction), emotional (responses), cognitive (problem-solving), and language (communication).
Delays occur when developmental patterns are distorted; they can be transient or persistent and influenced by environment and child-rearing practices.
Early detection of delays is crucial for minimizing long-term effects and facilitating complete rehabilitation.

Assessment of Development

Assessment methods include checklists like SOVS, standardized tests, and the Bayley Scales, covering adaptive behavior, cognitive, language, motor, and social-emotional skills.
Scores are standardized to allow comparison with norms; cut-off scores assist in diagnosis.

Theories of Learning, Cognition, and Memory

Cognition involves mental processes in learning and memory formation.
Historical learning theories include Original Sin (innate evil), Tabula Rasa (experiences shape adult characteristics), and Innate Goodness (children are good by nature).
Freud’s Psycho-sexual Theory connects early life experiences to adult personality traits.

Learning Mechanisms

Learning results in new knowledge and memory formation through neural connections.
Hebbian learning: "cells that fire together wire together," strengthening synaptic connections.
Long-term potentiation: synapse strengthening through repeated activation patterns.
Non-Associative Learning includes habituation (decreased response to non-threatening stimuli) and sensitization (increased response to potentially harmful stimuli).

Associative Learning

Involves associating stimuli with behavior; prominent types are classical conditioning (Pavlov) and operant conditioning (Skinner).
Classical Conditioning: associates a neutral stimulus with an innate reflex through pairing.
Operant Conditioning: behavior is shaped by reinforcement, which can be positive (reward) or negative (removal of discomfort).

Contact Lens Types and Materials

Hard lenses: PMMA (polymethyl methacrylate), durable but lack oxygen transmissibility.
Rigid Gas Permeable (RGP) lenses: allow oxygen transmission; increasingly used over PMMA.
Soft lenses include hydrogel (water-containing) and silicone hydrogel (enhanced oxygen permeability).

Contact Lens Types by Ocular Surface

Corneal lenses: partially cover the cornea, made from rigid materials.
Scleral lenses: cover cornea and sclera, can be rigid or soft materials; used for specialty purposes.

Key Lens Parameters and Designs

Lens diameter: measuring maximum external dimension, varies between lens types (rigid vs. soft).
Base curve (BOZR): crucial for fitting; should match flatter corneal meridian for rigid lenses.
Lens thickness affects comfort and fit; measured at the geometric center or edges.

Lens Design Variations

Monocurve, bicurve, and tricurve designs affect fit and optical correction.
Optic zone diameter is larger than pupil diameter, limiting the lens diameter based on other parameters.

Peripheral and Intermediate Curves

Peripheral curve specified by width and radius of curvature; influences fit and comfort.
Intermediate curves bridge the peripheral and central areas of the lens, affecting overall design and fit.
