Study Notes
Sensory Processes: Attention and Perception
- Five primary sense organs: eyes (vision), ears (hearing), skin (touch), nose (smell), and tongue (taste).
- Functions of senses include survival and sensuality, enriching life experiences.
- Colors and perceptions of the world are products of sensory and perceptual processes, not inherent properties of objects.
- Sensation is the transformation of external energy (like light) into neural impulses that create an awareness of conditions.
- Perception involves the elaboration and interpretation of sensory information, influenced by past and present experiences.
Sensation
- Sensation is the conversion of one form of energy into another, enabling the brain to process sensory events.
- Different thresholds exist:
- Absolute Threshold: Minimum physical energy required for a sensory experience.
- Difference Threshold: Minimal change in stimulus intensity that can be detected.
- Background stimuli can affect sensation, as seen with stars being visible only at night due to the daylight background.
- Expectations and experiences guide sensation, making it a complex process beyond a simple binary detection.
- Distal stimulus refers to the real-world object, while the proximal stimulus is the resulting optical image on the retina.
Perception
- Major task of perception: interpreting proximal stimuli to identify distal stimuli and understand the outside world.
- Perception involves recognizing physical properties (shape, size) alongside past experiences and cognitive processes.
- The process of perception includes:
- Sensory processes
- Environmental stimulation
- Analysis and identification of stimuli
- Perceptual synthesis and organization
Illusions and Hallucinations
- Illusions involve distorted perceptions of stimuli that do exist, while hallucinations involve perceiving non-existent stimuli.
- Classic examples of illusions include the Muller-Lyer illusion and the Ponzo illusion, which demonstrate how our perception can be misleading.
Attention
- Attention is critical for focusing on specific sensory messages amidst distractions.
- Types of attention:
- Divided Attention: Attempting to focus on multiple stimuli simultaneously, which can lead to accidents.
- Selective Attention: Prioritizing specific incoming sensory information while filtering out others.
- Functions of attention include serving as a sensory filter, response selection, and enabling consciousness.
Key Concepts
- Perceptual organization depends on several determinants such as figure-ground organization and perceptual consistency.
- Perceptual Constancy: Recognition that an object's characteristics (shape, size, brightness) remain stable despite changes in the retinal image.
- Depth Perception: The ability to perceive three-dimensional space and accurately judge distances, crucial for activities like driving and catching objects.
Additional Insights
- Mechanisms of attention and perception impact everyday life and inform various applications in psychology, art, and design.
- Exploring extra-sensory perception can lead to understanding phenomena beyond traditional sensory modalities.
