What is the function of chromosomes
To carry hereditary traits children inherit from their parents
How many chromosomes are they
There are 46 total chromosomes
23 from the mother's ovum
23 from the father's sperm
What is a genotype
An individual's complete genetic makup, including traits in recessive genes
What is a phenotype
An individual's expressed characteristics (green eyes, red hair)
What are carriers
Traits that are in our genotype but unexpressed as a phenotype
What is a dominant-recessive trait
One gene pair is dominant and controls the trait.
The recessive gene is in the genotype but not part of the phenotype
What are polygenic traits
Produced by interaction of many traits
What 2 things must happen to have a trait become a Phenotype
2 levels of interraction must occur
1 Gene-Gene Interaction
2 Gene-Environment interaction
In a dominant-recesive pattern, what controls the trait
One gene pair is dominant and controls the trait
Recessive gene is in genotype, not part of phenotype
An example of dominant-recessive pattern is
Brown eyed father
Blue eyed mother (brown eye gene)
Hypothetically, 1 in 4 chance child will have blue eyes
3 in 4 chance children will have brown

Variables
Major part of experiments, have at least 2 values and can refer to qualities, conditions, behaviors, traits or events
Experimental and Control group
The group exposed to the treatment or condition = Experimental
Control = Not exposed
The scientist controls what type of variable
Independent
An experimental research considers what causes
Psychological experiences
Behavioral changes
Physiological processes
To discover the reasons people change and the reason they stay the same, developmental research is conducted utilizing what two research designs
Cross-sectional research
Longitudinal research
Cross sectional research is
A research that works with groups of subjects of different ages but who are similar
Longitudinal research is
When the same group is observed for a certain length of time
Sequential research is
The use of both cross-sectional and longitudinal methods together - Also called Cross-sequential, sequential, time-sequential

Ethology is defined
As the study of the natural unfolding of animal behavior
Who was Bowlby
A human ethology researcher, who considered attachment behavior - Loss of proximity to the object of attachment produces anxiety (ex: mother-infant attachment)
What is psychoanalytic theory

Freud was
Founder of psychoanalysis
According to Freud, the mind is separated by 3 levels which are
Conscious - Mental experiences that can be recalled
Preconscious - Memories and perceptions can be recalled at will
Unconscious - Bottom layer of feelings and memories cannot be recalled at will
The 3 structures of personality as defined by Freud are
The Id - Symbol of unconscious, contains inherent biological drives
The Ego - Focusses on reality principle, guides individuals to express sexual, aggressive impulses
The Superego - Contains the conscious, gives individuals extreme feelings of guilt

Classical conditioning
His experiment involved a dog, a bell and food
Concluded that if bell sounded before hungry dog given food, dog would salivate at sound of bell
Food=Unconditional stimulus
Salivation=Unconditioned response
Bell=Conditioned stimulus
Complete Process was termed classical conditioning (aka respondent conditioning)

Positive reinforcement example
Train a dog to retrieve newspapers and giving it with a reward once object is returned
Negative reinforcement
example
Carrying an umbrella when you know it is going to rain
(therefore avoiding getting wet)
