Association Areas of the Cortex01:21

Association Areas of the Cortex

8.4K
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Stereotypes, Prejudice, and Discrimination

94.6K
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...

Somatosensation01:33

Somatosensation

42.7K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Prosopagnosia01:24

Prosopagnosia

610
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...

Facial Feedback Hypothesis01:24

Facial Feedback Hypothesis

470
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...

Somatosensory, Motor, and Association Cortex01:24

Somatosensory, Motor, and Association Cortex

1.9K
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at...

Area of Science:

  • Social neuroscience
  • Cognitive psychology
  • Neuroimaging

Background:

  • The outgroup homogeneity effect describes the tendency to perceive members of social outgroups as more similar to each other than members of one's own ingroup.
  • Understanding the neural underpinnings of this effect is crucial for addressing intergroup biases.

Purpose of the Study:

  • To investigate the neural representations associated with the outgroup homogeneity effect using functional magnetic resonance imaging (fMRI).
  • To examine how the brain processes and individuates faces from racial ingroups versus outgroups.

Main Methods:

  • fMRI repetition suppression was employed to measure neural activity in face-selective regions.
  • Participants viewed pairs of faces (White and Black targets) and performed discrimination tasks.
  • Face-selective regions, including the fusiform face area (FFA), were localized using an independent task.

Main Results:

  • Neural activity in the FFA distinguished between different White faces but not between different Black faces.
  • Face-selective cortical regions showed reduced discrimination for outgroup members compared to ingroup members.
  • Behavioral data indicated slower discrimination and poorer memory for outgroup individuals.

Conclusions:

  • The outgroup homogeneity effect may stem from early-to-mid-level visual processing that creates overlapping neural representations for outgroup members.
  • These findings suggest that perceptual processes contribute to the subjective experience of outgroup homogeneity.
  • This research highlights the role of visual perception in shaping social cognition and intergroup relations.
