Psy Ch 4 Sec 1 Sensation

What is sensation?

• Sensation is the process of detecting stimuli from the environment through our sensory organs.
• Sensation is the process of transmitting stimuli to the environment.
• Sensation is the process of ignoring stimuli from the environment.
• Sensation is the process of creating stimuli in the environment.

What is perception?

• Perception is the process of tasting food.
• Perception is the ability to see in the dark.
• Perception is the process of recognizing and interpreting sensory information.
• Perception is the act of hearing sounds.

What is the absolute threshold in terms of sensation?

• Minimum intensity of a stimulus needed to detect a particular stimulus 50% of the time.

• The maximum intensity of a stimulus required to cause pain

• The largest amount of intensity from a stimulus needed to override a particular stimulus 50% of the time.

What is a stimulus in terms of sensation?

• A stimulus in terms of sensation is any object or event that elicits a sensory or neural response in an organism.
• A stimulus is a form of cognitive processing
• A stimulus is a type of sensory receptor
• A stimulus is a response to an organism's behavior

What is the difference threshold in terms of sensation?

• The difference threshold is the maximum amount of change in a stimulus that can be detected
• The difference threshold in terms of sensation is the minimum amount of change in a stimulus that can be detected by an observer.
• The difference threshold is not related to sensation
• The difference threshold is the same for all individuals

What is signal-detection theory in terms of sensation?

• Signal-detection theory is a framework used to explain how people perceive stimuli based on their emotions.
• Signal-detection theory is a framework used to explain how people make decisions about the presence of a stimulus, considering sensitivity and decision-making.
• Signal-detection theory is a term used to describe the process of sensory adaptation in response to stimuli.

What is sensory adaptation?

• Sensory adaptation is the process by which sensory receptors become more responsive to constant stimuli over time.
• Sensory adaptation is the process by which sensory receptors adapt to different types of stimuli simultaneously.
• Sensory adaptation is the process by which sensory receptors remain static and do not change their responsiveness to stimuli.
• Sensory adaptation is the process by which sensory receptors become less responsive to constant stimuli over time.
