Database Thesaurus
A database thesaurus is a built-in tool that helps users identify the appropriate standardized index terms for their literature search. When an initial search term is too broad and returns an overwhelming number of records, the thesaurus can provide more specific index terms to help narrow down the results to highly relevant articles.

What is a database index term in the context of academic literature searches?
Match each component of an academic database search with the description that best explains its role in organizing and locating psychological research.
A researcher investigating 'low mood' finds that a database uses the standardized phrase 'Major Depressive Disorder' to categorize all related records. If the researcher searches using this specific index term, they will retrieve relevant articles even if the authors used different keywords—such as 'unhappiness' or 'sadness'—in their titles or abstracts.
Arrange the steps of a literature search process to demonstrate an analysis of why keyword searches can be inconsistent and how to resolve this using the database's organizational structure.
True or False: A database index term is a standardized phrase used to categorize research consistently, allowing researchers to find relevant articles even if authors used different keywords to describe the same topic.
An academic database may assign the standardized phrase 'Adolescence' to categorize publications, even if the original authors used varied keywords like 'teenagers' or 'youth.' How does this standardized indexing help a researcher who is performing a literature search?
A researcher critiquing a literature search strategy determines that relying solely on author-provided keywords is 'insufficient' for a systematic review because it lacks consistency across different publications. To ensure the highest level of rigor and exhaustive retrieval, the researcher argues that one must instead utilize the database's _____ terms, which are standardized phrases used to categorize research regardless of the specific words authors choose.
A psychology student is learning to search an academic database for literature on male-female differences. Match each search scenario on the left with the most accurate outcome or explanation on the right, based on how database index terms function.
A researcher conducts two separate searches on male-female cognitive differences: one using the informal phrase 'sex differences in memory' and one using the database's _____ 'Human Sex Differences.' By comparing the two result sets, the researcher determines that the second search is more comprehensive because every publication on that topic is assigned the same fixed phrase—regardless of the vocabulary each author individually chose.
A student has already completed a literature search using only informal author-chosen keywords and must now evaluate whether the search was sufficiently comprehensive. Arrange the following steps in the correct order for critically evaluating and justifying the quality of a literature search strategy in terms of database index term use.
Define a database index term and describe its primary function when conducting a literature search in an academic database.
Justify why the student should use database index terms instead of relying on their own list of keywords, and explain how this decision ensures a comprehensive search.
A psychology student is writing a research proposal and wants to search for publications comparing males and females. The database uses the standardized index term 'Human Sex Differences' for this topic. Applying your knowledge of database organization, how should the student execute their search, and why will this retrieve a paper even if the authors only used the keyword 'gender gaps'?

What is a database search term?
Arrange the steps a researcher would take to refine their use of database search terms, starting from an initial broad inquiry and moving toward a focused set of results.
A psychology student is using an academic database to find sources for a literature review. Match each specific research objective with the most effective database search terms to retrieve highly relevant records while filtering out irrelevant ones.
A psychology researcher analyzes their search results for the term 'stress' and finds thousands of records spanning from 'post-traumatic stress disorder' to 'cellular stress' to 'economic stress.' True or False: Based on the broad diversity of these results, the researcher can conclude that 'stress' is currently acting as a search term with high specificity for a study focused on PTSD.
Researchers often need to experiment with different combinations and specificities of search terms because academic databases contain millions of records.
A student searching a psychology database for a paper on 'the impact of sleep on memory' finds that the broad search term 'memory' returns millions of records. Why would experimenting with a more specific phrase, such as 'sleep deprivation and spatial memory,' be the most appropriate next step in the research process?
A psychology researcher evaluates their database search strategy for a project on 'the impact of prenatal stress on infant temperament.' They judge the search term 'stress' as being an inadequate choice for this specific literature review. This evaluative judgment is based on the fact that the term 'stress' lacks sufficient _____ to filter out millions of unrelated records, such as those concerning engineering or plant biology.
A psychology student is searching PsycINFO for sources for different research projects. Match each problematic search situation to the most appropriate corrective action based on how database search terms work.
A student searches PsycINFO using only the term 'memory' and retrieves hundreds of thousands of records covering neuroscience, clinical disorders, educational psychology, and animal cognition. She analyzes this result and concludes: 'Because a single broad term matches records across too many unrelated topics, I need to experiment with different _____ of search terms to narrow my results to highly relevant articles on my specific topic.'
A researcher wants to find articles on 'cognitive behavioral therapy for childhood anxiety disorders' using an academic database. Arrange the following actions in the order that best represents a principled, evaluative approach to developing an effective search term strategy, from first to last.
Define what a database search term is and state the primary reasons why researchers must experiment with different combinations and levels of specificity when using them to search academic databases.
Based on your comprehension of database search terms, explain why Marcus retrieved so many irrelevant records and decide what adjustments he should make to his search terms to retrieve highly relevant articles.
Apply your knowledge of database search terms to design an initial search strategy for a student who wants to find research on 'how social media usage relates to adolescent depression.' What specific search terms and strategy should they use to avoid retrieving millions of general records?

When conducting a literature search in psychology, what is the primary function of a database thesaurus?
Arrange the steps a researcher would take to refine an overly broad literature search using a Database Thesaurus.
A researcher searching for 'memory' in a psychology database finds that the search returns over 100,000 results, most of which are not relevant to their specific interests. To narrow the search and identify more specific, standardized terms to focus the results, the researcher should use the database ________.
A psychology researcher is refining a literature search using a database thesaurus. Match each specific search obstacle with the analytical function of the database thesaurus that best resolves it.
A researcher argues that a database thesaurus is an inefficient tool for refining a search because it restricts the researcher to a standardized vocabulary rather than allowing for the broader range of natural-language keywords. This argument is an accurate evaluation of the tool's utility for narrowing down an overwhelming number of search results.
A database thesaurus is a built-in search tool designed to help researchers identify standardized index terms and locate more specific terms to narrow down an overly broad search.
How does a database thesaurus differ from a typical English language thesaurus when a researcher is conducting a literature search?
A psychology student is learning to use a database thesaurus during a literature search. Match each research situation to the most appropriate action the student should take using the thesaurus.
A student analyzing why thesaurus-derived index terms produce more targeted results than natural-language terms concludes that the key advantage is that index terms are _____, meaning every article covering the same concept is tagged identically regardless of how individual authors phrased that concept.
A researcher is evaluating the most defensible strategy for conducting an efficient and targeted literature search using a database thesaurus. Arrange the following steps in the order that best justifies progressively refining a broad natural-language term into a well-targeted, index-term-driven search.
Define a database thesaurus and describe its primary function for a researcher who is conducting a literature search in a database such as PsycINFO.
Explain how the database thesaurus will help the student resolve this search issue. In your explanation, identify what the thesaurus provides and give a specific example of how a broad search term can be refined using this tool based on the database's features.
If a researcher does not know the appropriate standardized index terms for a search, how should they apply the database thesaurus to refine an initial search term that is returning too many results?
