Q

theories serve 2 important functions in science, what are they?

A
  • theories organize and explain a large number of previous observations
  • theories help to generate new knowledge by pointing us in a direction where we can look to discover new aspects of behaviour

Q

what is the scientific principal of parsimony?

A
  • if multiple theories are equally successful at explaining the same phenomenon, parsimony dictates the least complex therapy is the most desirable because it is the easiest to falsify

the simpler theory is more parsimonious

Q

how can past research generate research ideas?

A
  • as you become familiar with the research literature on a topic you may notice inconsistencies in the result and create a new experiment

Q

what is a hypothesis?

A

statement about a phenomenon that may or may not be true, informed by past research or derived from a broader theory and requires further evidence to support it or refuse it

if little or no research has been conducted previously on a topic, there might not be enough existing evidence to formulate a strong hypothesis

21
Q

what types of questions does a hypothesis usually try to answer?

A

generally try to answer questions related to “how” and “why” things are the way that they are

22
Q

what are the 2 categories of hypothesis?

A
  • directional hypothesis
  • nondirectional hypothesis
23
Q

what is a directional hypothesis?

A

specify precisely or predict the outcome of any research project

EX. group z will score significantly higher than group t

24
Q

what is a non-directional hypothesis?

A

do not precisely specify the outcome of a research project

EX. group z scores will differ significantly from the scores of group t

25
Q

what is a predication?

A

more specific hypothesis

EX. hypothesis: a crowded environment results in worse performance on cognitive tasks compared to an uncrowded environment

prediction: participants in the uncrowded condition will perform better on a delayed recall task than other participants in the crowded condition

26
Q

what do we do to the hypothesis if results are consistent with prediction?

A

do not reject the hypothesis and is supported by the evidence

27
Q

what are variables?

A

all the factors / characteristics in your study that can change or vary

EX. gender, weight and. mood

28
Q

what is an operational definition?

A

exact statements about how the variables in your study will be observed and measures

EX. love is warm and fuzzy
love is expensive

29
Q

what is an independent variable?

A

these are the variables in your study that are manipulated by the examiner

quantity or quality of independent variable changes according to the wishes of the experimenter

30
Q

what is a dependant variable?

A

variables which change or not as a result of manipulation of the independent variable

observed, scored or measured in a study

31
Q

what are the 6 sections in a research article?

A
  1. abstract
  2. introduction
  3. method
  4. results
  5. discussion
  6. references
32
Q

what is the hypothesis?

A
  • summary of research
  • 100 -250 words

read abstract to decide whether the article could help you learn about your research topic

33
Q

what occurs in the introduction?

A

researcher outlines the problem that has been investigated

  • past research and theories relevant are described
  • current study is introduced
  • hypothesis is stated
  • builds a logical case of why the study is important
34
Q

why read the intro?

A

read intro to find out the purpose of the study, the past research and theories relevant to the study and hypothesis

35
Q

what is the method section?

A

provided info about exactly how the study was conducted including any details necessary for the reader to repeat the study

36
Q

what is the non-experimental method (also called the correlational method)?

A

both variables of interest are measured an non are manipulated

EX. tell people to log hours of exercise and write how happy they are

37
Q

what is the experimentation method?

A

investigate the relationship between the independent variable and dependant variable

38
Q

why read the method section?

A

to find out characteristics of the participants, what they were asked to do, what materials were used and overall study design

39
Q

what is the results section?

A

researcher presents the findings, which have typically arisen from a statistical analysis of the data collected

either presented in: narrative form or statistics

narrative form: result described in words

40
Q

why read the results?

A

for sentences, statistics, tables and graphs that summarize the pattern of findings

41
Q

what occurs in the discussion section?

A

researcher reviews the current study from various perspectives

-realize flaws in study
- how results compare with past research
-suggestions of future research

42
Q

why read the discussion?

A

for conclusions about the hypothesis

43
Q

why read the reference section?

A

to look up citations you noticed in earlier sections

44
Q

what is literature review?

A

uses narrative techniques to summarize the research using words only

45
Q

what is meta analysis?

A

uses statistical techniques to reanalyze past data

46
Q

creating a theory is private, when does the research become public?

A

when the first participant is observed

47
Q

once a researcher has written a paper in APA, what’s the next setp?

A

submit article to a scholarly scientific journal to be considered for publication

all peer-reviewed journals are scholarly publications but not all scholarly publications are peer reviewed

48
Q

running out study involves what 5 steps?

A
  1. closing a sample of participants
  2. collecting data from those participants
  3. analyzing the data
