"Bias is an inclination toward something, or a predisposition, partiality, prejudice, preference, or predilection."
The tendency of researchers to influence the outcomes of an experiment based on their own expectations or preferences.
Definition of Experimental Bias: Understanding the meaning of experimental bias and how it affects the results of an experiment is necessary for anyone interested in experimental psychology.
Types of Experimental Bias: There are various types of experimental bias, such as observer bias, confirmation bias, selection bias, expectation bias, and many others, each of which affects an experiment in different ways. Learning about these types of biases and how they manifest is crucial when studying experimental psychology.
Causes of Experimental Bias: Understanding the causes of experimental bias is essential when learning about experimental psychology. Factors such as sample selection, experimenter expectations, or measurement errors can cause Experimental Bias.
Impact of Experimental Bias: Being aware of experimental bias helps researchers understand the consequences of flawed studies, invalidation of results and the poor decisions that can result from bad science. The impact of experimental bias can alter the significance and reliability of a study's outcome.
Ways to Reduce Experimental Bias: A better understanding of experimental bias improves experimental evaluation, and helps researchers improve the validity of their studies. They can incorporate techniques such as double-blind studies, randomized sampling, or controlling variables to reduce the potential for experimental bias.
Examples of Experimental Bias: Exploring real-world case examples can give students a better idea of how experimental bias may appear and how it should be better studied. For example, The placebo effect is an example of the investigatory bias, while the Hawthorne effect is an example of the experimenter bias that can be put to practice for a better study outcome.
Ethical Considerations: Experimental behavioural psychology comes with ethical concerns, such as using animal & human subjects, violating the privacy of participants, the risk of physical harm, and informed consent. Learning about these ethical considerations helps researchers abide by the guidelines & rules and conduct a well-done experiment with the right care and consideration for ethics.
Measuring and Quantifying Experimental Bias: There are different ways to quantify and measure experimental bias, such as statistical tests, validation studies, and peer review. These methods can help researchers assess, control and eliminate them.
Controlling for Experimental Bias: Researchers must implement various methods to measure, minimize or remove experimental bias from the study. they can only manage these biases by putting their findings to peer review or replicating studies to check their validity, records and credentials.
Importance of Replication and Peer Review: Replication and peer review are essential elements of experimental psychology. Replication enables others to confirm or dispute the findings of previous studies. Peer review provides a platform for a group of peers with expertise in a given field to judge research validity and recommend possible improvements. Correct repetition of the study helps promote the reliability and significance of research to bring in practical value for future decisions.
Confirmation Bias: When researchers favor or search for information that confirms their preconceptions or hypotheses, ignoring information that contradicts their beliefs.
Experimenter Bias: When the researcher's own beliefs, attitudes, or expectations influence the outcomes of the study, either consciously or unconsciously.
Sampling Bias: When the sample is not representative of the population being studied, leading to inaccurate generalizations.
Selection Bias: When participants in the study are not chosen randomly, leading to a biased sample.
Hawthorne Effect: A phenomenon where participants in a study change their behavior simply because they know they are being observed, leading to inaccurate results.
Social Desirability Bias: A tendency for participants to present themselves in a favorable light, leading to an overestimation of positive traits or behaviors.
Maturation Bias: Changes in the participants over the course of the study that affect the outcome, such as physical or mental growth, hormonal changes, or environmental factors.
Regression to the Mean: A tendency for extreme scores to return to the average in subsequent measurements, leading to overestimation or underestimation of effects.
Placebo Effect: When participants in a study experience a change or improvement in their condition simply because they believe they are receiving treatment, even if the treatment is inactive.
Demand Characteristics: Cues or clues in the study that suggest to participants what the researcher expects them to do, leading to altered behavior or results.
