Theories and Causes Flashcards
Theory
Allows us to assemble and communicate existing knowledge effectively
Transaction
Interaction of child and environment contributing to disorder development
Continuity
Developmental changes are gradual and quantitiative, predictive of future behaviour
Discontinuity
Changes are abrupt and qualitative, not predictive of future behaviour
Adaptational failure
Failure to master or progress in accomplishing milestones
Organization of development
Early patterns of adaptation evolve with structure over time and transform into higher order functions
Sensitive periods
Windows of time when environmental influences are enhanced
Developmental psychopathology
Approach to describing and studying disorders that stress the importance of developmental tasks
Developmental cascades
Child’s previous experience may spread across other systems and alter course of development– chain reaction
5th month of pregnancy
Most axons have reached their final destination but target cells cant accommodate them all
When do sensory and motor functions mature
First 3 years
Limbic system
Perceptual and instinctive centers strongly affected by early experience
When are the pre frontal cortex and cerebellum wired
5-7
When is there major brain restructuring
9-11 during puberty
How many genes do we have
20- 25000
Gene
Stretch of DNA that produces a protein that will shape how we respond to the environment
Gene Environment interaction
GxE– Genes influence how we respond to the environment and the environment influences our genes
Epigentics
Change in gene activity due to environmental factors
Behavioural genetics
Connections between genetic predisposition and observed behaviour
Molecular Genetics
Association between variations in DNA sequence and variations in a particular trait
Polygenic
Multiple genes and influences cause disorder
Brain stem
Autonomic functions necessary to stay alive
3 parts of the brain stem
Hindbrain
Midbrain
Diencephalon
Hindbrain
Medulla, pons, cerebellum– regulate autonomic function
Midbrain
Coordinates movement with sensory input
RAS
Reticular Activating System for arousla and tension– in midbrain
