Subject and experimenter errors in behavioral research with particular reference to motor behavior

Area of Science:

• Behavioral Science Research
• Experimental Psychology

Background:

• Research in behavioral science is susceptible to errors introduced by both participants and experimenters.
• Understanding these error sources is crucial for ensuring the validity of study findings.

Purpose of the Study:

• To identify and discuss sources of error in behavioral science research originating from participants and experimenters.
• To suggest methods for eliminating or mitigating these identified errors.
• To explore the relevance of these errors in the context of motor behavior research.

Main Methods:

• Literature review and analysis of existing research on experimental errors.
• Identification of common participant (S) and experimenter (E) biases and errors.
• Discussion of the interaction between participants and experimenters as a source of error.

Main Results:

• Participant errors include over-helpfulness, attempts to deceive the experimenter, and the Hawthorne effect.
• Experimenter errors can arise from subtly cueing participants about expected outcomes, personal characteristics, or situational factors.
• Experimenter bias can occur through intentional or unintentional transmission of cues regarding the study's hypothesis.

Conclusions:

• Awareness and proactive management of participant and experimenter errors are essential for robust behavioral science research.
• Implementing strategies to control demand characteristics and experimenter bias can enhance research integrity.
• The identified error sources have direct implications for the design and execution of motor behavior studies.
