Summary
Psychology research topics vary by region and time, challenging the idea of universal patterns. This study used topic modeling to reveal implicit differences in global psychology research activities.
Area of Science:
- Psychology
- Cultural Studies
- Behavioral Science
Background:
- Cultural studies increasingly examine human behavior's universality and diversity globally.
- Previous discussions on research activity patterns in psychology lacked quantitative analysis.
- Researchers intuitively recognize regional and temporal diversity in psychological research.
Purpose of the Study:
- To quantitatively analyze geographic and temporal trends in psychology research activities.
- To identify implicit characteristics of research diversity using topic modeling.
- To test the universality hypothesis in human behavior and mental processes research.
Main Methods:
- Topic modeling applied to abstracts of psychological articles.
- Author affiliations and publication periods used as covariates.
- Comparison with keyword frequency analysis to validate topic modeling findings.
Main Results:
- North-Central America showed higher proportions of basic research topics; Europe showed higher proportions of clinical research topics.
- Topic modeling revealed implicit regional differences not apparent in keyword frequency analysis.
- A trend of increasing neuroscience topics was observed over time, with exceptions in specific journals.
Conclusions:
- Psychology research activities exhibit significant diversity across geographic regions and time periods.
- The assumption of universality does not extend to human behavior or the study of mental processes.
- Quantitative analysis provides deeper insights into implicit patterns of research diversity.

03:46Qualitative Analysis
22.8K
For solutions containing mixtures of different cations, the identity of each cation can be determined by qualitative analysis. This technique involves a series of selective precipitations with different chemical reagents, each reaction producing a characteristic precipitate for a specific group of cations. Metal ions within a group are further separated by varying the pH, heating the mixture to redissolve a precipitate, or adding other reagents to form complex ions.
For instance, group IV...

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

01:12Quantitative Analysis
703
Quantitative analysis is a technique for measuring the amount of specific constituents in a sample. When the sample's composition is unknown, qualitative analysis is performed first to identify its components, which ensures that the correct substances are measured during the quantitative phase.
In quantitative analysis, two key measurements are made: the sample quantity and a property proportional to the amount of the analyte (the substance being analyzed). This forms the basis of the...

Often, psychologists develop surveys as a means of gathering data. Surveys are lists of questions to be answered by research participants, and can be delivered as paper-and-pencil questionnaires, administered electronically, or conducted verbally. Generally, the survey itself can be completed in a short time, and the ease of administering a survey makes it easy to collect data from a large number of people.
