Summary
Sexism-related stigma negatively impacts women's pain perception. Studies show females experience reduced pain thresholds and altered pain processing when exposed to sexism, affecting their physical pain experience.
Area of Science:
- Psychology
- Neuroscience
- Sociology
Background:
- Stigmatized individuals face devaluation and negative outcomes similar to physical pain.
- The effect of identity-related stigma on physical pain perception remains largely unexplored.
Purpose of the Study:
- To investigate whether sexism-related stigma influences pain perception in females.
- To provide behavioral and electrophysiological evidence of this effect.
Main Methods:
- Experiment 1: Assessed pain threshold/tolerance using the Cold Pressor Test in females under sexism-related stigma paradigms.
- Experiment 2: Measured pain ratings for fixed-intensity nociceptive laser stimuli.
- Experiment 3: Recorded laser-evoked potentials (LEPs) to assess neural responses to pain.
Main Results:
- Females exhibited reduced pain threshold and tolerance in the Cold Pressor Test.
- Pain ratings for laser stimuli were increased under stigma conditions.
- Electrophysiological data showed altered early neural responses (N1, P2) and low-frequency components in LEPs.
Conclusions:
- Sexism-related stigma significantly affects pain perception in females.
- Findings demonstrate both behavioral and neurophysiological evidence of stigma's impact on pain sensitivity.
- This research highlights the complex interplay between social stigma and sensory experience.

02:16Stereotype Content Model
15.0K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

02:55Stereotypes, Prejudice, and Discrimination
93.3K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

02:09Stereotype Threat and Self-fulfilling Prophecies
40.7K
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...

01:20Pain
972
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

01:44Nociception
31.8K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

01:29Blood and Nerve Supply to the Bones
12.7K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
