Methods for Deriving Hypotheses from Theories

Example of an 'If-Then' Hypothesis: Cockroach Study

Which logical framework best describes the fundamental connection when a researcher derives a specific hypothesis from a broader scientific theory?

A researcher states: 'If the decay theory of forgetting is accurate, then participants will recall fewer words from a list after a 24-hour delay than after a 1-hour delay.' In this logical 'if-then' structure, the expected decrease in recalled words represents the broad scientific theory rather than the specific observable phenomenon.

In psychological research, theories and hypotheses are linked by a logical 'if-then' structure. Consider the statement: 'If drive theory is accurate, then insects should run faster when others are present.' Match the parts of this logical structure to their specific roles in the scientific process.

To connect a general theory to a testable research prediction, scientists follow a specific deductive logical structure. Arrange the following components in the correct sequence to represent this $if-then$ flow, moving from the broadest conceptual premise to the most specific empirical outcome.

In the $if-then$ logical structure used to derive research predictions from theories, the $if$ component represents the specific observable phenomenon.

Which of the following best describes the logical function of the $if-then$ relationship in psychological research?

In the deductive 'if-then' framework of psychological research, if the predicted observable phenomenon (the 'then' clause) is empirically disproven, the researcher's logical conclusion is that the underlying theory is _____.
