Abduction refers to lateral movement away from the midline of the trunk, as in raising the arms or legs to the side horizontally.

In psychology, abduction refers to the process of creating explanations or hypotheses to explain observations or facts. It involves developing possible explanations for a phenomenon, based on incomplete information or limited data. Abduction is often used in scientific inquiry, where researchers use observations to develop a hypothesis that may explain a particular phenomenon.

For example, a researcher might observe that people who exercise regularly tend to have better mental health outcomes than those who do not exercise. Using abduction, the researcher might develop a hypothesis that regular exercise can have a positive impact on mental health outcomes, and design a study to test this hypothesis.

Another example of abduction in psychology could be a therapist who is trying to understand the root cause of a patient's anxiety. Based on the patient's behavior, the therapist might develop a hypothesis that the patient has experienced a traumatic event in the past, leading to their anxiety. The therapist can then explore this hypothesis with the patient and work on developing a treatment plan.
