Fixed Action Patterns01:06

Fixed Action Patterns

17.6K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

619
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...

Muscles for Facial Expressions01:14

Muscles for Facial Expressions

4.8K
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...

Relative Risk01:12

Relative Risk

2.0K
Relative risk (RR) is a statistical measure commonly used in epidemiology to compare the likelihood of a particular event occurring between two groups. This metric is important for evaluating the relationship between exposure to a specific risk factor and the probability of a particular outcome. It plays a crucial role in medical research, public health studies, and risk assessment. Relative risk quantifies how much more (or less) likely an event is to occur in an exposed group compared to an...

Action Potential01:31

Action Potential

4.4K
Neurons communicate by firing action potentials—the electrochemical signal that is propagated along the axon. The signal results in the release of neurotransmitters at axon terminals, thereby transmitting information to the nervous system. An action potential is a specific "all-or-none" change in membrane potential that results in a rapid spike in voltage.
Membrane potential in neurons
Neurons typically have a resting membrane potential of about -70 millivolts (mV). When they receive...

Summary

Preventing facial expressions of fear and anxiety during risky decision-making tasks increases risk-taking behavior. This suggests that facial feedback influences how individuals approach uncertain situations.

Area of Science:

  • Psychology
  • Behavioral Science
  • Neuroscience

Background:

  • Risk-taking behavior is often accompanied by emotions like fear and anxiety.
  • Facial expressions are known to modulate emotional experiences and cognitive processes.

Purpose of the Study:

  • To investigate whether inhibiting facial actions associated with fear and anxiety influences risk-taking.
  • To determine if facial feedback plays a role in modulating decisions in uncertain situations.

Main Methods:

  • Two studies were conducted using risky decision-making tasks, including the Balloon Analogue Risk Task and a jack-in-the-box task.
  • Participants in the experimental condition had their facial muscle movements restricted using medical tape and mouth guards.
  • Control groups received non-restrictive tape application and no mouth guard.

Main Results:

  • Disrupting facial muscle activation led to increased risk-taking behavior, indicated by more balloon pumps and lever turns.
  • Participants with restricted facial actions exhibited greater engagement with risky tasks.

Conclusions:

  • Facial expressions significantly modulate risk-taking behavior.
  • Inhibiting the physical manifestation of anxiety can lead to bolder decisions in the face of risk.
