Q

What was the goal of the structuralists?

A

They wanted to identify and measure the basic mental elements and their attributes and understand how they combine to produce complex conscious thought. They believed that the structure of consciousness must be understood before talking about its function.

Q

What was the name of the school of thought that American psychologists founded? What did this school of thought study/believe?

A

Functionalism.

Functionalism can be defined as how the mind functions to help organisms adapt to their environments. Consciousness exists for the purpose of helping organisms to survive and adapt to the physical world. Functionalists use experimental methods to understand learning, memory, problem solving, motivation, emotion, beliefs and concepts of self.

Q

How did James define empiricism? Does his idea fit with our current understanding of empiricism? Why or why not?

A

James thought that all aspects of experience, both observable and not observable, both objective and subjective could be studied.

This does not fit with our current understanding.

Empiricism is defined as studying observable and measureable phenomena and experience.

Q

List three reasons why James is considered the first American psychologist.

A

There were no professors of psychology in America until James began teaching in 1875.

Within 2 decades of the beginning of his psychology course, about 2 dozen universities had classes in psychology, three psychology journals were published and a professional psychology society had been formed.

He introduced experimental psychology to America.

He published the first psychology textbook, Principles of Psychology

He applied psychological principles to teaching, which became the core of educational psychology.

He was largely responsible for getting the Rockefeller Foundation and similar groups to allocate millions of dollars to the development of mental hospitals and the training of mental health professionals.

Q

List two strengths of scientific paradigms.

A

They facilitate the search for knowledge

They define the boundaries of what is known

They specify the questions to be explored

They establish the ground rules for conducting a search for more knowledge.

43
Q

What is the weakness of scientific paradigms?

A

They limit the worldview of scientists studying within them. Questions that lie outside the boundaries of the current set of assumptions are not studied. The assumptions on which paradigms are founded are never tested, so that if the paradigms are not true, then the entire inquiry is wasted.

44
Q

Name two paradigms in psychology that you believe to be true.

A

Experience changes behavior.

Behavior can be learned through observation.

45
Q

Define scientific inquiry.

A

A systematic, controlled, empirical, and critical investigation of hypothetical propositions about the presumed relations among observed phenomena.

46
Q

Name three characteristics of scientific inquiry and explain them.

A

Scientific research is public: science depends on the publication of information that is collected by scientists so that other scientists may replicate or extend their work.

Science is objective: scientific research deals with facts instead of interpretations of facts and tries to be unbiased.

Science is empirical: science uses direct observation to obtain knowledge of observable phenomena.

Science is systematic and cumulative: new scientific research builds on previous scientific knowledge.

Science is predictive: The findings can be applied to populations to determine if behavior is actually predictable.

47
Q

What is an operational definition?

A

A carefully worded statement of the exact procedures (operations) used in a research study.

48
Q

Name and describe two ways of doing descriptive research.

A

Cases Studies: looking at one or a few individuals (or groups) and making inferences about large populations of people or non-humans based on what is observed in just a few.

Naturalistic Observation: humans and non-humans are observed in their typical environments, so that natural, or typical behaviors that are unaffected by the observer can be documented.

Surveys: asking many people about their thoughts, feelings or behaviors on some limited topic to determine what percentage of people think, feel or behave in a particular way.

49
Q

Why does your instructor say all humans are psychologists?

A

All of us use descriptive sampling techniques in our everyday life. We all make generalizations about human and non-human behavior based on a few observations of a few individuals or a few conversations with a few people.

50
Q

What is the goal of correlational research?

A

To determine if a relationship exists between two variables.

51
Q

Does a correlational relationship imply causation? Why or why not?

A

Variables are not controlled or manipulated in correlational research to determine if one is causing the other.

52
Q

Define experimental research.

A

Scientific inquiry in which variables are manipulated and controlled to determine cause and effect.

53
Q

Tell me why descriptive, correlational and experimental inquiry are all empirical.

A

All rely on observable and measurable phenomena.

54
Q

What is random assignment?

A

People (or non-humans) are randomly assigned to groups in an experiment. Each individual has an equal chance of being in any group.

55
Q

Why do we use random assignment in psychology experiments?

A

To reduce sampling error.

56
Q

Define control group.

A

The group in an experiment that does not receive the experimental treatment.

57
Q

Define independent variable.

A

The variable that is being manipulated, that is, the treatment that is given or not given to different groups.

58
Q

Define dependent variable:

A

The variable that is measured to determine if the independent variable changes it.

59
Q

In the Mythbuster’s video that we saw, what were the independent variables?

A

Voice - nice words or mean words

Music - classical or heavy metal

60
Q

In the Mythbuster’s video that we saw, what were the dependent variables?

A

Height, number of pea pods produced, and weight (in grams)

61
Q

In a cause and effect relationship, the ______________ variable is the possible cause and the _________________variable is the possible effect. (independent and dependent).

A

Independent - possible cause

Dependent - possible effect

62
Q

Tell me the similarities and differences among descriptive, correlational and experimental inquiry.

A

Descriptive:

Looks at observable behavior to identify and describe it.
Describe a specific behavior.
Cannot make predictions or determine causality from the information collected.
Variables are not manipulated and participants (subjects) are not put into groups.

Correlational:

Looks at observable behavior to determine if there is a relationship between two variables.
Variables are not manipulated and participants (subjects) are not put into groups.
Can make predictions about the level of one variable based on knowledge of the other variable.
Cannot determine causality.

Experimental:

One variable is intentionally manipulated
Participants are put into groups through random assignment
Experimental research can determine causality.

63
Q

Define a population in scientific inquiry.

A

All members of a group in which a researcher has an interest.

64
Q

Define sample in a scientific inquiry.

A

A subset of a population that is assumed to have the same characteristics as the population.

65
Q

Why do we use samples and not populations in most psychological studies? Name three reasons.

A

Time, it takes too long to look at a whole population

Money, it is too expensive to look at a whole population.

The researcher does not have access to the whole population.

66
Q

What is sampling error?

A

Error that exists because our sample does not represent our population.

67
Q

How can sampling error be reduced?

A

Use random sampling and large samples.

68
Q

Can a sample be selected so that there is zero sampling error? Why or why not?

A

No. By random chance, the sample selected may be biased or not represent the population in some way, but the experimenter is unaware of this.

69
Q

Why do we us inferential statistics to compare our groups in experimental research?

A

To estimate the amount of error that may exist in our sample

70
Q

The use of ______________________ statistics can reduce sampling error.

A

Inferential

71
Q

When do researchers have to use biased samples? Give an example.

A

When for legal or ethical reasons, large numbers of people (or non-humans) cannot be studied. EX: Studying the effects of a new medicine on people with brain tumors.

72
Q

What is nominal data? Give one example.

A

Data grouped by categories. Names or words are used instead of numbers. There is no order or ranking.

Ex: Grouping by gender

73
Q

What is ordinal data? Give example.

A

Data collected as numbers that can be ranked from high to low, but there is no indication of how much higher or lower one participant is from another.

Ex: The expression of any emotion.

74
Q

What is interval data? Give one example.

A

Data collected as numbers that can be ranked from high to low and the exact differences between values can be determined. There is no true zero. Measuring reaction time in seconds.

Ex: Measuring well-being on a validated scale for that concept.

75
Q

What is ratio data? Give one example.

A

Data collected as numbers that can be ranked from high to low and the exact differences between values can be determined. There is a true zero.

Ex: Measuring reaction time in seconds.

76
Q

What is the main difference between ordinal data and interval or ratio data?

A

Interval and ratio measurements tell us by how much participants differ.

77
Q

Name three measures of central tendency.

A

Mode, median and mean

78
Q

What is a frequency distribution?

A

Data put into a table or graph that shows how many participants have each score.

79
Q

What is a normal curve?

A

When large data sets are collected, in many cases, most of the data points cluster around some middle value and then taper off. This occurs in many sets of data in nature. The shape of the data set on the graph looks like a bell.

68% of data values will be within one standard deviation of the mean; about 95% will lie within two standard deviations and about 99.7 within three standard deviations.

80
Q

What is a skewed distribution?

A

The place where most data points cluster is not normally distributed, but when drawn on a graph, the data shows peaks to the right or the left of the middle.

81
Q

What is the most frequently used measure of central tendency?

A

The mean.

82
Q

Define mean.

A

The point behind which all the deviations sum to zero.

83
Q

Which of the below data sets would be appropriate for using the mean as a measure of central tendency and why?

A

A, because the mean is affected by extreme scores so that a true, representative middle is not formulated. Thus, the mean is appropriate for a data set with a small range.

A. 2, 2, 2, 2, 3, 3, 5, 5, 6, 6, 7, 7, 10,12

B. 5, 5, 5 5, 7, 7, 7, 9, 9, 9, 200, 210, 5, 5

84
Q

Define Median.

A

The value in a distribution that has 50% of the cases above it and 50% below it; thus it is a middle point in a distribution.

85
Q

When is the median used as a measure of central tendency?

A

When the frequency distribution of the data is not normal and there is a skewed distribution.

86
Q

Define Mode.

A

The most frequently occurring score in a data set.

87
Q

If data is normally distributed, the __________________should be used as a measure of central tendency.

A

Mean

88
Q

If the data is skewed, the _________________ should be used as a measure of central tendency.

A

Median

89
Q

If the data is nominal, the ______________ should be used as a measure of central tendency.

A

Mode

90
Q

If there are extreme scores in the data set, the ________________ should be used as a measure of central tendency.

A

Median

91
Q

For nominal data the ________________ and ________________ should not be used as measures of central tendency.

A

Mean and median

92
Q

The most frequently used measure of central tendency is the ______________.

A

Mean

93
Q

The difference between the highest and lowest score on a data set is called the _________________.

A

Range

94
Q

What is an outlier?

A

Data points that lie far outside the range of most of the other scores.

95
Q

What is the effect of outliers on the range?

A

They increase the size of the range and do not give a true picture of the variability of the rest of the data.

96
Q

What measure of range can be used to diminish the effect of outliers?

A

Interquartile range (IQR)

97
Q

What is the most frequently used measure of variability?

A

Standard deviation

98
Q

Define standard deviation.

A

A statistic that provides an overall measurement of how much participant’s scores differ from the mean score of their group. It is an average of the deviations of the scores from their means.

99
Q

What affects the size of the standard deviation?

A

The variability of the scores.

100
Q

If all participants had the same score, what would the standard deviation be?

A

Zero

101
Q

When is the term participants used in psychological publications?

A

Human subjects who have freely consented to participating in research.

102
Q

When is the term subjects used in psychological publications?

A

Those who have not freely consented to participating in research. Most commonly currently used for non-humans. Can be used for humans who have not consented to be participants in a research study (e.g., naturalistic observation).

103
Q

When is the term respondents used?

A

It is used for participants who have responded to a survey or taken an examination.

104
Q

What are the APA and APS?

A

American Psychological Association

Association for Psychological Science

The two major psychological professional groups that psychologists belong to.

Clinicians tend to belong to APA and experimentalists to APS.
