Final answer:
Publication is important in psychological research to disseminate results to the scientific community and allow for peer review, replication, and expansion of research findings.
Step-by-step explanation:
Publication is important in psychological research in order to disseminate results to the scientific community. By publishing their research findings in peer-reviewed journal articles, psychologists allow other scientists to review, replicate, and expand upon their work.
Peer review, a process where other psychologists review and assess the validity of the research, ensures that the research is original, significant, logical, and thorough. Successful replications of published research findings contribute to the consensus and acceptance of those findings in the scientific community.
