Ethics in Research01:56

Ethics in Research

Today, scientists agree that good research is ethical in nature and is guided by a basic respect for human dignity and safety. However, this has not always been the case. Modern researchers must demonstrate that the research they perform is ethically sound.
Archival Research01:40

Archival Research

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...
Surveys02:16

Surveys

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.
Statistical Significance01:37

Statistical Significance

Once data is collected from both the experimental and the control groups, a statistical analysis is conducted to find out if there are meaningful differences between the two groups. A statistical analysis determines how likely any difference found is due to chance (and thus not meaningful). In psychology, group differences are considered meaningful, or significant, if the odds that these differences occurred by chance alone are 5 percent or less. Stated another way, if we repeated this...
Regulation of Expression Occurs at Multiple Steps02:24

Regulation of Expression Occurs at Multiple Steps

Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...
Blind Procedures02:07

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...

Area of Science:

  • Parapsychology
  • Research Methodology
  • Scientific Integrity

Background:

  • Preregistration is a method to reduce questionable research practices.
  • Early preregistration methods existed in parapsychology before mainstream adoption.
  • Previous research indicated registered reports in parapsychology had fewer significant results.

Purpose of the Study:

  • To examine the efficacy of the Koestler Parapsychology Unit's Study Registry (KPU SR) as an early preregistration procedure.
  • To compare the outcomes of preregistered parapsychology studies with non-preregistered ones.

Main Methods:

  • Compared studies preregistered on the KPU SR (established 2012) with non-preregistered parapsychology studies.
  • Analyzed the proportion of significant results in both preregistered and non-preregistered studies.
  • Utilized data from KPU SR submissions and contemporary journal publications.

Main Results:

  • Preregistered studies on the KPU SR reported significantly fewer significant results (16%) compared to non-preregistered studies (46.6%).
  • This finding aligns with previous research on preregistration's impact on result reporting.

Conclusions:

  • The KPU SR demonstrates effectiveness in reducing the rate of significant findings, similar to other preregistration methods.
  • Findings support the broader implementation of preregistration to enhance research integrity in parapsychology and beyond.
  • Further research is suggested to explore the long-term implications and optimal implementation of preregistration techniques.
