Psych 105 Flashcards
What is hindsight understanding?
Relies on explanations after the fact
What are Unobtrusive measures
recording behaviour in a way that keeps participants unaware that certain responses are being measured
What is included in descriptive research?
Describes behaviour in natural settings, case studies; naturalistic observation; surveys
What are correlational studies?
relationship between or among variables
What are experimental studies?
Cause and effect relationships
What are the advantages of case studies?
Useful for rare phenomenon, can challenge the validity of theories, Can illustrate effectiveness of programs
What are the disadvantages of case studies?
Does not determine cause and effect very well, researcher bias
What is naturalistic observation?
The researcher will observe behaviour as it occurs in its natural setting. Avoids influencing behaviour
What are the three components to correlational research?
1: the researcher measures one variable
2: the researcher measures a second variable
3: the researcher statistically determines whether the variables are related.
Does correlation establish causation?
no
What is spurious association?
3rd variable problem
Describe positive correlation
as one variable increases so does the other and vice versa. As height increases so does weight
Describe negative correlation
Variables change in different directions, if one variable increases the other decreases. As number of hours of daylight decreases, number of depression symptoms increase
Do scatterplots depict correlation?
yes
What are the three essential characteristics in an experiment?
1: manipulate one variable
2: measure whether this variable produces change in the other
3: control for other factors that may influence results
What is the experimental group?
The group that receives a treatment
What is the control group?
Not exposed to treatment (basis for comparison)
What is an independent variable?
What is being manipulated by the experimenter
What is a dependent variable?
What is being measured by the experimenter & influenced by the independent variable
The descriptive method involves..
all variables being measured, in a natural context where extraneous factors are not controlled
The experimentation method involves..
Independent variables manipulated, typically done in a laboratory, where extraneous factors are controlled
What is external validity?
The degree to which results of a study can be generalized to other populations
What is meta-analysis?
A statistical procedure that combines results from multiple studies on the same topic to test the overall significance
What are the threats to validity of research?
Extraneous variables, placebo effect, experimenter expectancy / bias
What is psycholinguistics?
The scientific study of the psychological aspects of language
What are semantics?
The meanings of words and sentences
What is a syntax?
rules for combination (grammar)
What is a phoneme?
The smallest units of sound recognized as separate - from the bottom up
What are morphemes?
Breaks down word to meaning - smallest units of meaning
What is speech segmentation?
Perceiving where each word within a spoken sentence ends and begins
What are pragmatics?
The social context of language
What is the function of the Broca’s area?
The ability for speech production
What is the function of the Wernicke’s area?
Speech comprehension - understanding meaning
What is Wernicke’s Aphasia?
word repetition - word salad
What is expressive Aphasia?
Inability to express but able to comprehend
What is the function of the primary motor cortex?
Controls the facial muscles / head, speaking words, involved in many aspects of language
What are algorithms?
Formulas that automatically generate solutions (math formulas)
What are heuristics?
General problem solving - mental shortcuts
What is anchoring?
The base sample that other products need to meet the standard of
What does mental imagery involve?
Spatial representation, visual scanning tasks
What is metacognition?
Knowing your own cognitive abilities
What is metacomprehension?
Accuracy of judging what you do and don’t know
What is metamemory?
Awareness of memory abilities
What is the function of the psychometric approach?
To map the structure of intellect and what mental talents underlie in the test performance
What is the function of the cognitive processes approach?
Cause and effect - what processes allow you to use skills?
What is the g factor?
High mental capacity - easy to learn anything
What is s intelligence?
Special abilities and intelligence
What are Thurstone’s 7 primary abilities?
1: Space- visual sense

3: Word fluency
4: Number facility - dealing with numbers
5: Perceptual speed - recognizing visual patterns
6: Rote memory- memorizing
7: Reasoning
What is crystalized intelligence?
Applying previously learned knowledge to current problems
What is fluid intelligence?
Dealing with new situations without previous knowledge
What is the triarchic theory of intelligence?
1- metacomponents
2- performance components
3- knowledge-aquisition components
What are Gardeners’ Multiple Intelligences?

2- Logical / mathematical
3- Visuospatial
4- Musical
5- Bodily kinesthetic
6- Interpersonal
7- Intrapersonal
8- Naturalistic
9- Spiritual
What are the four branches of emotion detection
1- perceiving emotion
2- using emotions to facilitate thought
3- understanding emotions
4- managing emotions
What are advantages of managing emotions?
Stronger emotional bonds, greater success, less depression
What is an aptitude test?
Measure potential for future learning and performance
Does intelligence predict lifespan?
Yes
Has the brain increased in size?
yes
Is intelligence genetically determined?
no, a third is due to environment
What IQ score shows that someone is intellectually gifted?
130 or higher, 10% of population
What is a “critical period”?
The age in development where experiences must occur
What is a “sensitive period”?
The optimal age range of development
What occurs during the germinal stage of pregnancy?
The first two weeks - Zygote attaches to uterine wall
What occurs during the Embryonic stage of pregnancy?
2nd-8th week - placenta and umbilical cord develop, tube connected neural pathways (spinal cord)
What occurs during the fetal stage of pregnancy?
