Summary
COVID-19 research in psychology maintained rigor despite rapid publication. Studies showed stronger designs, larger samples, and greater openness compared to non-COVID research.
Area of Science:
- Psychology
- Scientific Publishing
Background:
- Journals altered policies during the COVID-19 pandemic to expedite knowledge dissemination.
- Concerns arose that accelerated publication might compromise scientific rigor and accuracy.
Purpose of the Study:
- To compare the methodological rigor of COVID-19-related psychological research with non-COVID and pre-COVID research.
- To assess changes in design features, sampling, and transparency practices.
Main Methods:
- A comparative analysis of 100 COVID-19 articles (2020-2022) against 100 non-COVID articles from the same issues and 100 pre-COVID articles (2017-2019).
- Articles were systematically coded for design, sampling, and openness/transparency practices.
Main Results:
- COVID-19 research, while often observational, utilized stronger longitudinal designs over cross-sectional ones.
- COVID-19 studies demonstrated increased sample sizes, justified by a priori power analyses.
- Higher rates of pre-registration for hypotheses and analysis plans were observed in COVID-19 research.
- Open data, materials, and code sharing were more prevalent in COVID-19 studies.
Conclusions:
- Psychological research on COVID-19 did not exhibit diminished methodological rigor.
- Pandemic-era research practices in psychology, including openness and robust design, met or exceeded pre-pandemic standards.

01:13Psychology as a Science
667
Psychology, as a scientific discipline, aims to understand the mind and behavior through rigorous and systematic methods. The foundation of psychological research is evidence-based, relying heavily on the scientific method to derive and validate knowledge. This structured approach ensures that findings are reliable, valid, and applicable to broader contexts.

01:20Psychological Responses to Stress
44
Psychological responses to stress encompass the various cognitive and emotional reactions individuals experience when faced with challenging or threatening situations, such as a job loss. Prolonged exposure to stressors can disturb emotional balance, increasing negative emotions (e.g., anxiety and sadness) and diminishing positive emotions (e.g., joy and satisfaction). These persistent emotional shifts are associated with an increased risk of both physical illness and mental health issues, such...

01:24Humanistic Psychology

Humanistic psychology emerged in the mid-20th century as a response to the deterministic and pessimistic nature of behaviorism and psychoanalysis. While behaviorism focused on observable behaviors influenced by the environment and psychoanalysis delved into unconscious motivations, both theories suggested that human actions lacked free will. In contrast, humanistic psychology offers a perspective that emphasizes the innate potential for goodness and growth within every individual.

01:40Archival Research
15.9K
Some researchers gain access to large amounts of data without interacting with a single research participant. Instead, they use existing records to answer various research questions. This type of research approach is known as archival research. Archival research relies on looking at past records or data sets to look for interesting patterns or relationships. For example, a researcher might access the academic records of all individuals who enrolled in college within the past ten years and...

01:29Theoretical Approaches to Psychological Disorder
93
The development of psychological disorders, which are characterized by deviant, maladaptive, and personally distressing behaviors, has been explored through several theoretical approaches.
Biological approach
The biological approach posits that internal, organic factors are the primary causes of such disorders. This perspective emphasizes brain structure and function, genetic predispositions, and neurotransmitter imbalances. For example, schizophrenia has been associated with both genetic...
