Chapter 2 - Research Enterprise In Psych Flashcards
Measurement & Description (goal of sci enterprise)
Develop measurement techniques that make it possible to describe behavior efficiently
Scientific Approach to Behavior
Assumes that events are governed by some lawful order
Understanding & Prediction (goals if sci enterprise)
Scientists believe that understanding events can help explain why they occur
Hypothesis
Used to evaluate scientists understanding
Testable prediction
A tentative statement about a relationship between two variables
Variables
Any measurable conditions, events etc. that can be controlled or observed in a study
Any part of situation that can vary or change
Application & Control (goal of sci enterprise)
Psychology attempts to apply research findings to practical problems
Once people understand a phenomenon, they can control it better
Theories
Broad statements of underlying principles used to explain a set of observations
Constructed to better understand behavior
A system of interrelated ideas used to explain a set of observations
Steps of Scientific Investigation
Theory ➡️ Hypothesis ➡️ Empirical Research: Select Research Method & Design the Study ➡️ Collect Data ➡️ Analyze Data ➡️ Draw Conclusions ➡️ Report Findings
Operational Definition (hypothesis)
Describes actions or operations that will be used to measure or control a variable
Participants or Subjects
People or animals involved in study whose behavior is systematically observed
Data Collection Techniques
Procedures for making empirical observations and measurements ( direct observation, questionnaires, interviews etc)
Journal
Periodical that publishes technical & scholarly material
Peer Review Process (publishing)
Process of publishing allows other experts to evaluate and critique findings
Advantages of Scientific Approach
- Clarity & precision: enhance communication of ideas
2. Relative intolerance of error
Experiment
Research method
Variables are investigated under carefully controlled conditions & observes whether any changes occur in a second variable
Independent Variable
X
Varied in order to see impact on other variable
Dependent Variable
Y
Hypothesized to be affected by manipulation of independent variable
Control Condition (placebo)
Factor being studied is omitted while all other conditions are maintained
Can have multiple controls
Experimental Condition
Condition where variable of interest is applied
Key Elements of Experiment
(Conditions)
Control Condition
Experimental Condition
Blindness (in experiment)
Participant is unaware of their specific treatment condition
Ex. Not aware if placebo or not
Double Blindness (in experiment)
Both experimenter & participant are unaware (if placebo or not)
Randomization (in experiment)
Participants are randomly assigned treatment groups
Key Characteristics of a Good Scientist
- Curiosity
- Open Mindedness
- Skepticism
- Parismony
