  • This paper presents, first, a formal exploration of the relationships between information (statistically defined), statistical hypothesis testing, the use of hypothesis testing in reverse as an investigative tool, channel capacity in a communication system, uncertainty, the concept of entropy in thermodynamics, and Bayes’ theorem. This exercise brings out the close mathematical interrelationships between different applications of these ideas in diverse areas of psychology. Subsequent illustrative examples are grouped under (a) the human operator as an ideal communications channel, (b) the human operator as a purely physical system, and (c) Bayes’ theorem as an algorithm for combining information from different sources. Some tentative conclusions are drawn about the usefulness of information theory within these different categories. (a) The idea of the human operator as an ideal communications channel has long been abandoned, though it provides some lessons that still need to be absorbed today. (b) Treating the human operator as a purely physical system provides a platform for the quantitative exploration of many aspects of human performance by analogy with the analysis of other physical systems. (c) The use of Bayes’ theorem to calculate the effects of prior probabilities and stimulus frequencies on human performance is probably misconceived, but it is difficult to obtain results precise enough to resolve this question.

FAQs

In Experimental Psychology, A Significant Difference Refers To A? ›

Generally, psychologists consider differences to be statistically significant if there is less than a five percent chance of observing them if the groups did not actually differ from one another.

What is the most distinctive characteristic of the experimental method? ›

The experimental method involves the manipulation of variables to establish cause-and-effect relationships. The key features are controlled methods and the random allocation of participants into controlled and experimental groups.

What is the difference not likely due to chance? ›

This means that a “statistically significant” finding is one in which it is likely the finding is real, reliable, and not due to chance. To evaluate whether a finding is statistically significant, researchers engage in a process known as null hypothesis significance testing.

What is introspection AP psychology? ›

Introspection: A technique used by early scientific psychologists consisting of precise examination and description of an individual's conscious experience, typically in response to stimuli presented by the researcher.

How do research psychologists know their results are not likely due to chance? ›

How do research psychologists know their results are NOT likely due to chance? Conducting an experiment rather than a correlational study. Randomly assigning research participants to the experimental or control groups. The use of a double-blind procedure.

What are the characteristics of experimental psychology? ›

Characteristics of Experimental Psychology

The existence of two or more groups or circumstances to enable comparisons to be made between them. It is not possible to conduct experiments with only one group or condition to compare. Management of an independent variable, represented by various conditions or values.

What are the three important characteristics of experimental design? ›

In general, designs that are true experiments contain three key features: independent and dependent variables, pretesting and posttesting, and experimental and control groups. In a true experiment, the effect of an intervention is tested by comparing two groups.

Is a statistically significant difference is one that is likely due to chance alone? ›

Statistical significance refers to a result that is not likely to occur randomly but rather is likely to be attributable to a specific cause. A goodness-of-fit test helps you see if your sample data is accurate or somehow skewed.

Is statistically significant if it is unlikely to have occurred by chance? ›

Results are said to be statistically significant when the difference between the hypothesized population parameter and observed sample statistic is large enough to conclude that it is unlikely to have occurred by chance.

What significant difference means that results that are seen are most likely not due to chance or sampling error? ›

A "significant difference" means that the results that are seen are most likely not due to chance or sampling error. In any experiment or observation that involves sampling from a population, there is always the possibility that an observed effect would have occurred due to sampling error alone.

What is introspection experimental method in psychology? ›

Introspection is a psychological process that involves looking inward to examine one's own thoughts, emotions, judgments, and perceptions. In psychology, introspection refers to the informal process of exploring one's own mental and emotional states.

What are the two types of introspection? ›

Psychologists differentiate between two types of introspection: self-reflection and self-rumination.

What part of psychology is introspection? ›

Introspection is the examination or observation of one's own mental and emotional processes. Through introspection, we can gain knowledge about our inner workings. Introspection is sort of like perception, but also unlike perception in that it doesn't involve the five senses.

What makes results significant in psychology? ›

A study result is statistically significant if the p-value of the data analysis is less than the prespecified alpha (significance level). In our example, the p-value is 0.02, which is less than the pre-specified alpha of 0.05, so the researcher concludes there is statistical significance for the study.

Why does a psychologist want the results to be statistically significant? ›

Researchers in the field of psychology rely on tests of statistical significance to inform them about the strength of observed statistical differences between variables. Research psychologists understand that statistical differences can sometimes simply be the result of chance alone.

What does it mean when a researcher finds that her results are statistically significant? ›

In other words, a statistically significant result has a very low chance of occurring if there were no true effect in a research study. The p value, or probability value, tells you the statistical significance of a finding.

What are the distinctive characteristics of experimental research? ›

True experiments have four elements: manipulation, control , random assignment, and random selection. The most important of these elements are manipulation and control. Manipulation means that something is purposefully changed by the researcher in the environment.

What is the unique feature of experimental research? ›

Treatment manipulation is a unique feature of experimental research. A treatment manipulation helps you to control the 'cause' in the cause and effect relationship.

What is the major advantage of the experimental method? ›

Advantages of Experimental Research

Experimental research allows you to test your idea in a controlled environment before taking the research to clinical trials. Moreover, it provides the best method to test your theory because of the following advantages: Researchers have firm control over variables to obtain results.

What is the unique advantage of the experimental method? ›

The advantages of the experimental method are as follows: The researchers can have control over variables: The researchers can manipulate variables used in the experiment to understand and observe the phenomenon as per the changes in the environment.
