Negative and Positive Feedback

Negative and Positive Feedback

Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires maintaining an internal dynamic equilibrium:

Feedback Inhibition

Feedback Inhibition

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

Stereotype Threat and Self-fulfilling Prophecies

Stereotype Threat and Self-fulfilling Prophecies

When we hold a stereotype about a person, we have expectations that he or she will fulfill that stereotype. A self-fulfilling prophecy is an expectation held by a person that alters his or her behavior in a way that tends to make it true. When we hold stereotypes about a person, we tend to treat the person according to our expectations. This treatment can influence the person to act according to our stereotypic expectations, thus confirming our stereotypic beliefs. Research by Rosenthal and...

Positive and Negative Feedback Loops

Facial Feedback Hypothesis

Facial Feedback Hypothesis

Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role of...

Effects of feedback

Effects of feedback

Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

Summary

Negative feedback during interrogations increases response changes and anxiety, unlike neutral feedback. A second interviewer did not significantly alter responses but elevated trait anxiety in participants during simulated forensic interviews.

Area of Science:

Psychology
Forensic Psychology
Legal Psychology

Background:

Limited research exists on feedback's role in interrogative suggestibility without leading questions.
Existing research often focuses on leading questions, neglecting other factors influencing testimony accuracy.

Purpose of the Study:

To investigate the impact of negative feedback on interviewee responses in simulated forensic interviews.
To examine the effect of a second interviewer on interviewee responding and anxiety levels.

Main Methods:

Participants watched a crime video, were interviewed, and then re-interviewed after receiving either neutral or negative feedback.
The presence or absence of a second interviewer was also manipulated.
Measures included response changes, reported state anxiety, and perceived interview difficulty.

Main Results:

Negative feedback led to significantly more response changes, higher state anxiety, and increased perceived interview difficulty compared to neutral feedback.
The presence of a second interviewer did not significantly affect interviewee responding but did elevate trait anxiety scores.

Conclusions:

Findings support Gudjonsson and Clark's (1986) model of interrogative suggestibility, highlighting feedback's influence.
Negative feedback can increase suggestibility and distress in interviewees.
The role of multiple interviewers warrants further investigation regarding its impact on anxiety.
