Repeated measures design
In repeated measures design, each participant is part of both the E-group and the C-group.
Matched participants design
In the matched participants design a researcher identifies a variable that is a likely confound, and eliminates the effects of this variable from the experiment. Participants can be ranked in accordance with their scores on this variable and then allocated to the respective groups
What are piaget’s theories?
- sensori motor stage - birth -2
- pre-operational stage - 2 - 7
- concrete operational stage - 7 - 12
- formal operational stage - 12+
- sensori motor stage description
infants learning about their world through their senses (hearing, seeing, feeling) and actions
- sensori motor stage major accomplishments
object permanence
object permanence
infants come to understand that an object still exists when it is no longer in sight, for example (peek a boo) thats why children are so fascinated because before they develop object permanence they think you are really gone and thats what makes it so funny/ scary for them.
develops in the sensori motor stage
- pre-operational stage description
children continue to develop and they use symbols, images and language to represent their world
- pre-operational stage major accomplishments
symbolic thinking
anism
egocentrism
symbolic thinking
is where children develop symbols to represent objects or events. this thinking allows the child to participate in pretend or make believe play.
develops in the pre-operational stage
anism
means that the child will believe that inanimate objects are real
develops in the pre-operational stage
egocentrism
is when children are unable to view the world from someone else’ perspective.
develops in the pre-operational stage
- concrete operational stage description
children can now perform basic mental problems that involve physical objects. Display less centration and egocentrism. Children may struggle to solve problems that require abstract thinking
- concrete operational stage major accomplishments
reversibility
conservation
conservation
children lack conservation, they cannot understand that objects stay the same despite changes in appearance.
develops in the concrete operational stage
reversibility
when children start understanding that inversion (reversing) an action will return it to its original state
Develops in the concrete operational stage
- formal operational stage description
children are able to think logically and methodically about physical and abstract problems
- formal operational stage major accomplishments
can think flexibly
can do hypothetical problems
can form and test a hypothesis
schizophrenia
schizophrenia is a psychotic disorder, a disease of the brain that causes patients to suffer from deluded thinking, hallucinations and depression and in most cases anxiety
delusions
false beliefs that are strongly held despite evidence that they cannot be true
hallucinations
hallucinations are seeing something that isn’t really infant of you. false perceptions in the absence of sensory input
paranoia
paranoia is delusions of persecution, unwarranted jealousy, or exaggerated self-importance, typically worked into an organized system
disorganised speech and behaviour
a person experiencing disorganised speech has thought
patterns that do not make sense. Speech is di cult to follow and can simply be words strung together that sound similar or are made up.
how prevalent is schizophrenia
about 1% will develop schizophrenia at one stage in their life, normally around late teens, early 20’s
two-hit hypothesis
The two-hit hypothesis model provides a framework to explain the relationship between the genetic and environmental risk factors associated with schizophrenia.
