1.1 Sensation & Perception: Welcome To Our World Flashcards
What is the definition of Sensation?
Sensation is the ability to detect a stimulus, and perhaps, turn that detection into a private experience.
What is the definition of Perception?
Perception is the act of giving meaning to a detected Sensation
What are the 6 scientific approaches to studying Sensation & Perception?
- Thresholds
- Scaling
- Signal Detection Theory
- Sensory Neuroscience
- Neuroimaging
- Computational Models
What is the Conceptual approach to studying Thresholds, and what is an example?
The conceptual approach to studying Thresholds consists of the study of minimal and maximum tolerance of sensations.
An example: Studying the minimum decibel level of a particular frequency.
What is the conceptual approach to studying Scaling, and what is an example?
To study different ways in which individuals experience their own private world.
What is the conceptual approach to studying Signal Detection Theory?
What are some examples?
To study how one can perceive and decide upon difficult decisions.
A Doctor who must decide if a growth on a mammogram is cancerous or benign.
What is the conceptual approach to studying Sensory Neuroscience?
What are some examples?
To understand how sensory receptors and nerves undergird our perceptual experience.
Brain activity when tasting hot food.
What is the conceptual approach to studying Nueroimaging?
What is an example?
Nueroimaging allows us to see traces of an experience as it takes place in the brain.
An EEG while we watch a series of funny visuals.
What is the conceptual approach to studying Computational Models?
What is an example?
Perception is inborn and shaped by experience. Computational models allow us to see how abilities and environment interact and make predictions about our perceptions.
How an infant in one culture perceives speech sounds.
