Impossibility of Proving a Theory

Alternative Theories Explaining the Same Hypothesis

What do researchers conclude when a systematic empirical study yields statistically significant results that are consistent with the hypothesis?

Arrange the logical steps a researcher takes to provide empirical support for a scientific theory in psychology.

A team of researchers is evaluating whether their latest study results provide empirical support for their respective theories. Match each researcher's outcome with the correct conclusion regarding the status of their theory.

A researcher investigating cognitive dissonance finds that their experimental data align with their hypothesis, but the results fail to achieve statistical significance. True or False: This outcome allows the researcher to conclude that the underlying theory is supported because the theory successfully accounted for the observed direction of the results.

When a systematic empirical study yields statistically significant results that are consistent with the hypothesis, the underlying theory's validity is strengthened because it has made an accurate prediction.

In psychological research, what does it mean when a researcher concludes that a scientific theory is 'supported' by the results of an empirical study?

A researcher is evaluating whether a systematic study provides sufficient grounds to conclude that a theory's validity has been strengthened. Even if the data aligns with the theory's predictions, the researcher must judge the theory to be _____ if the results fail to achieve statistical significance.

Dr. Alvarez is testing the 'Cognitive Depletion' theory of self-control. Arrange the events in her research process in the correct chronological order to illustrate how an empirical study is used to support a scientific theory.

Analyze the following research outcomes and match each scenario to the correct logical conclusion regarding the underlying scientific theory.

Dr. Chen is evaluating a manuscript in which the authors claim their theory is definitively 'proven' because their systematic empirical study yielded statistically significant results consistent with their hypothesis. To adhere to scientific standards, Dr. Chen must instruct the authors to change their conclusion to state that the theory is _____, meaning it made an accurate prediction that strengthens its validity but does not establish absolute certainty.
