Factors Affecting Perception01:25

Factors Affecting Perception

Perception is influenced by perceptual set, context, motivation, and emotion. Perceptual set, or perceptual expectancy, refers to the tendency to perceive things in a particular way, influenced by previous experiences and expectations. This phenomenon affects the interpretation of stimuli, creating a set of mental tendencies and assumptions that impact sensory perceptions of sound, taste, touch, and sight.
An illustrative example of a perceptual set is the scenario where an airline pilot told...
Perception01:28

Perception

Perception is a fundamental psychological process that enables individuals to organize, interpret, and consciously experience sensory information. This process is crucial for understanding and interacting with the world around us. It includes both bottom-up and top-down processing, each playing a distinct role in how we perceive our environment.
Bottom-up processing begins at the sensory level, where receptors detect external environmental stimuli. These could include the tactile sensation of...
Parallel Processing01:20

Parallel Processing

The brain processes sensory information rapidly due to parallel processing, which involves sending data across multiple neural pathways at the same time. This method allows the brain to manage various sensory qualities, such as shapes, colors, movements, and locations, all concurrently. For instance, when observing a forest landscape, the brain simultaneously processes the movement of leaves, the shapes of trees, the depth between them, and the various shades of green. This enables a quick and...

Summary

Older adults exhibit age-related declines in reflective selective attention, impacting brain activity in the parahippocampal place area. This contrasts with preserved perceptual selective attention abilities in older individuals.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Neuroimaging

Background:

  • Selective attention is crucial for processing complex visual information.
  • Age-related cognitive changes can affect attentional processes.
  • The parahippocampal place area is vital for scene perception.

Purpose of the Study:

  • To investigate the impact of perceptual versus reflective selective attention on parahippocampal place area (PPA) activity in young and older adults.
  • To determine if age-related differences exist in processing faces versus scenes under different attentional demands.

Main Methods:

  • Functional magnetic resonance imaging (fMRI) was used to measure brain activity.
  • Participants viewed simultaneous face and scene stimuli.
  • Attentional conditions included perceptual presence and reflective refreshment of stimuli.

Main Results:

  • Both age groups showed similar PPA activation when attending to scenes during perceptual presence and reflective refreshment.
  • Equivalent PPA deactivation occurred in both groups when attending to faces during perceptual presence.
  • Older adults exhibited significantly less PPA deactivation than young adults when cued to reflect on faces.

Conclusions:

  • Reflective selective attention, but not perceptual selective attention, is disproportionately affected by aging.
  • Age-related disruptions are more pronounced in higher-level cognitive control processes like reflective attention.
  • Findings suggest distinct neural mechanisms underlying perceptual and reflective attention, with the former being more resilient to aging.
