Term
List the steps of the scientific method
Definition
1. Obtain a testable theory
2. Device a hypothesis
3. Conduct research and observe
Term
Define Case Study
Definition
An observation technique in which one person is studied in depth in the hope of revealing universal principles.
Term
Define Survey
Definition
a technique for ascertaining the self-reported attitudes or behaviors of people, usually by questioning a representative, random sample of them
Term
define false consensus effect
Definition
tendency to overestimate others agreement with us
Term
Prediction
Definition
all the cases in a group, from which samples may be drawn for a study. (Note: Except for national studies, this does not refer to a contry’s whole populations.
Term
Random sample
Definition
A sample that fairly represents a population because each member has an equal chance of inclusion
Term
NOTE TO SELF
Definition
Most surveys sample a target group.

Before believing survey findings, think critically: Consider the sample. You cannot compensate for an unrepresentative sample by simply adding more people

The best basis for generalizing is from a representative sample of cases
Term
Naturalistic observation –
Definition
observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation.

• Like the case study and survey methods, naturalistic observation does not explain behavior, it describes it.

• Naturalistic observations are also done with humans
Term
Cross-sectional study
Definition
a study in which people of different ages are compared with one another
Term
Longitudinal study
Definition
research in which the same people are restudied and retested over a long period.
Term
Correlations NOTE
Definition
Psychologists use numbers to describe the strength of a relationship expressed as a correlation. But they caution against illusory correlations and incorrectly inferring cause and effect.

• Describing behavior is a first step toward predicting it. When surveys and naturalistic observations reveal that one trait or behavior accompanies another, we say the two correlate
Term
correlation coefficient
Definition
a statistical measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. (ex: knowing how much aptitude test scores correlate with school success tells us how well the scores predict school success)


NOTE:
• Although the correlation coefficient tells us nothing about cause and effect, it can help us see the world more clearly by revealing the actual extend to which two things relate.

NOTES:
• correlations can range from +1.00 (scores on one measure increase in direct proportion to scores o another) to -1.00 (scores on one measure decrease precisely as scores rise on the other).

• Decreasing Correlation example: As toothbrushing goes up from zero, tooth decay goes down.

• Increasing Correlation example: One set of scores increases in direct proportion to the other set of scores’ increase

• Can help us see what the naked eye sometimes misses.
Term
Scatterplot
Definition
A graphed cluster of dots, each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables. The amount of scatter suggests the strength of the correlation (little scatter indicates high correlation) (also called a scattergram or scatter diagram)
Term
Correlation and Cuasation note :
Definition
• Among the most irresistible thinking errors made both by laypeople and by professional psychologists is assuming that correlation proves causation.. no matter how strong the relationship, it does not!
Term
Correlation and Cuasation note :
Definition
• Among the most irresistible thinking errors made both by laypeople and by professional psychologists is assuming that correlation proves causation.. no matter how strong the relationship, it does not!
Term
NOTE
Definition
• Correlation indicates the possibility of a cause-effect relationship, but it does not prove causation. Knowing that two events are correlated need not tell us anything about causation.
Term
Illusory correlation
Definition
The perception of a relationship where none exists. (when we believe there is a relationship between two things, we are likely to notice and recall instances that confirm our belief)

NOTES

• Illusory correlations help explain many a superstitious belief (more babies are born when the moon is full or that infertile couples who adopt become more likely to conceive) it’s only because those who conceive after they adopt are the ones that caught our attention, we’re less likely to notice those who adopt and never conceive, or those who conceive without adopting.

• Illusory correlations occur when we over-rely on the top left cell (figure), ignoring equally essential information in the other cells.

• When we notice random coincidences, we may forget that they are random and instead see them as correlated, thus, we can easily deceive ourselves by seeing what is not there.

Synapse
Definition
the junction between the axon tip of the sending neuron and dendrite or cell body of the receiving neuron. The tiny gap at this junction is called the synaptic gap or cleft
Term
Neurotransmitters -
Definition
chemical messengers that traverse the synaptic gaps between neurons. When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether that neuron will generate a neural impulse.
Term
Types of Neurotransmitters
Definition
Acetylcholine – enables muscle action, learning, and memory

Dopamine – influences movement, learning, attention and emotion

Serotonin – affects mood, hunger, sleep, and arousal

Norepinephrine – helps control alertness and arousal

Glutamate – a major excitatory neurotransmitter; involved in memory
Term
reuptake.
Definition
a process in whicch excel neurotransmitters are reabsorbed by the sending neuron
Term
Endorphins –
Definition
“morphine within” – natural, opiatelike neurotrsnmitters linked to pain control and to pleasure
Term
Overview of Neural Communication
Definition
The body’s circuitry, the nervous system, consists of billions of individual cells called neurons. A neuron received signals from other neurons through it’s branching dendrites and cell body, combines these signals in the cell body, and transmits an electrical impulse (the action potential) down its axon. When these signals reach the end of the axon, they stimulate the release of chemical messengers called neurotransmitters. These molecules pass on their excitatory or inhibitory messages as they traverse the synaptic gap between neurons and combine the receptor sites on neighboring neurons. Researchers are studying neurotransmitters to discern their role in behavior and emotion. Some drugs (agonists) excite by mimicking particular neurotransmitters or blocking their reuptake; others (antagonists) inhibit by blocking neurotransmitters.
Term

Social Phsicology Notes #2
Definition
Parents in every culture facilitate their children’s discovery of their world, but cultures differ in what they deem important. Asian cultures place more emphasis on school and hard work than does North American culture. This may help explain why Japanese and Taiwanese children get higher scores on mathematics and achievement tests.
Term
Environmental Influence –
Definition
Genetic influences are pervasive, but so are prenatal environments, early experiences, peer influences, and cultures. Sculpted by experience, neural interconnections multiply rapidly after birth. Human variations across cultures and over time show how differing norms, or expectations, guide behavior. Cultures differ in their norms for personal space, expressiveness, and pace of life

Relative Clarity
Definition
(Light and Shadow) Nearby objects refelct more light to our eyes. thus, giving two identical objects, the dimmer one seems farther away/

This illusion can lso contribute to accidents, as when a fog-shrouded vehicle, or one with only it's parking lights on, seems farther away than it is. Shading too, produces a sense of depth consisten with assummed light source. Our brains assume a simple rule: that light comes from above
