Chapter 6 Psychology

What is sensation?

• Sensation is the process of creating illusions in the mind.
• Sensation is the ability to predict future events.
• Sensation is the act of controlling emotions.
• Sensation is the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environemt

What is perception?

• Perception is the ability to see through walls.
• Perception is the process by which our brain organizes and interprets sensory information,

• Perception is the act of tasting food.
• Perception is the process of creating illusions in the mind.
• Perception enables us to recognize objects and events as meaningful.

sensory nerve endings that respond to stimuli

• sensory receptors

• sensory receivers

• sensory transmitters

• sensory detectors

Information processing that begins with the sensory receptors and works up to the brains integration of sensory information

• Top-down processing
• Ascending processing
• Bottom-up processing
• Inside-out processing

what type of processing allows your sensory systems to detect the lines, angles, and colors that form images?

• Bottom-up processing

• Olfactory processing
• Tactile processing
• Auditory processing

Information processing guided by higher level mental processes, as when we construct perceptions drawing on our experience and expectations

• Vertical processing
• Lateral processing
• Bottom-up processing
• Top-down processing

Answer explanation

you interpret what our senses detect

The conversion of one form of energy into another. In sensation, the transforming of physical energy, such as sights, sounds, and smells, into neural impulses our brain can interpret

What is the rough distinction between sensation and perception?

• Sensation involves complex analysis, while perception is a simple recognition process.
• Sensation and perception are interchangeable terms with no distinction.
• Sensation is the process of interpreting information, while perception is the initial detection of basic data.
• Sensation is the bottom-up process by which your sensory receptors and your nervous system receive and represent stimuli. Perception is the top-down process by which you brain creates meaning by organizing and interpreting what your senses detect

The minimum stimulus energy needed to detect a particular stimulus 50 percent of the time

• Sensory adaptation
• Difference threshold
• Weber's law
• Absolute threshold

A theory predicting how and when we detect the presence of a faint stimulus (signal) amid background simulation (noise). Assumes there is no single absolute threshold and that detection depends partly on a person's experience, expectations, motivation, and alertness

• Signal detection theory
• Noise detection theory
• Signal recognition theory
• Stimulus identification theory
