Part of the Series : Understanding Psychology

This program clarifies selected principles of science by contextualizing them through easily comprehensible applications of psychological research. Divided into five sections, the video illustrates the hypothetical-deductive model of scientific reasoning via Piaget’s classic conservation experiment and Donaldson and McGarrigle’s challenge of it; the analysis of statistics involving scenarios in which a record producer considers signing a new band and a student carries out IQ testing; the use of graphs to present data from a study of romance ads; the concept of statistical significance through the conducting of memory tests; and data interpretation through a study measuring levels of aggression. Viewable/printable educational resources are available online. (28 minutes)

Closed Captioned

How Science Works (02:21)
Scientists develop theories, test those theories, make necessary modifications and begin again. Based on his experiments, Piaget determined that children's cognitive abilities develop over time.

Challenging Piaget's Theory (01:18)
McGarrigle and Donaldson challenged Piaget's conservation experiment arguing children learn cognitive skills much earlier then Piaget's experiments showed.

Hypothetical Deductive Model (01:45)
The hypothetical deductive model is based on observing events and developing or revising ideas based on those observations.

Descriptive Statistics (02:56)
Dan, a record producer, uses descriptive statistics to help him decide which of two bands to sign.

Normal Distribution (02:51)
Education psychologists use IQ tests to test a child's ability to learn effectively.

Data Presentation (02:26)
Psychological research data is presented graphically depending on the needs of the psychologists.

Graphing Data (02:54)
Using pie charts, line graphs, scattergraphs, bar charts, etc. psychologists can view their data in various ways.

Statistical Analysis (02:49)
Using memory tests, psychologists must choose an appropriate statistical test to determine if their data results have statistical significance.

Getting the Right Results (02:25)
Statistics are used to determine if boys score better than girls on memory tests.

Data Interpretation (01:53)
Psychologists test respondents to determine if gender impacts level of aggression.

Mann-Whitney U Test (01:20)
Psychologists use a Mann-Whitney U test to determine if the differences between the two groups are the result of chance.

Measuring Validity (03:19)
Measuring the validity of the data collected is important to ensure the results achieved reflect true differences in the scores.
