Sensation And Perception

• What is sensation in the context of perception?

  Detection of stimuli
• Match the aspect with its corresponding process:

  Definition of sensation ↔️ Detection of stimuli by sense organs

  Definition of perception ↔️ Organization and interpretation of sensations

  Process of sensation ↔️ Receives raw sensory data

  Process of perception ↔️ Transforms sensory data into meaningful information
• Sensation involves transforming sensory data into meaningful information.

  False
• Where does perception take place in the human body?

  Brain
• What does the Central Nervous System (CNS) include?

  Brain and spinal cord
• Match the signal type with its description:

  Physical signal ↔️ Actual stimulus in the environment

  Neural signal ↔️ Electrical impulses for communication
• What is the absolute threshold in psychophysics?

  Smallest detectable stimulus
• Sensory adaptation increases sensitivity to stimuli over time.

  False
• What are the two factors that influence responses in signal detection theory?

  Sensitivity and decision criteria
• Match the outcome with its definition in signal detection theory:

  Hit ↔️ Correctly identifying a present stimulus

  Miss ↔️ Failing to identify a present stimulus

  False Alarm ↔️ Mistakenly reporting a stimulus

  Correct Rejection ↔️ Identifying the absence of a stimulus
• What are the three physical properties of light that influence perception?

  Length, intensity, and purity
• What does the purity of light refer to?

  Range of wavelengths
• Steps in the eye's conversion of light waves into neural impulses:

  1️⃣ Light waves enter cornea

  2️⃣ Light passes through pupil

  3️⃣ Lens focuses light on retina

  4️⃣ Photoreceptors convert light into neural signals
• What type of lens is used to focus on distant objects?

  Flat lens
• Match the eye part with its function:

  Cornea ↔️ Bends light waves

  Pupil ↔️ Controls light entry

  Lens ↔️ Focuses light on retina

  Retina ↔️ Contains photoreceptors
• What are the three types of cones in the eye used for color perception?

  S, M, and L-cones
• Steps in the visual pathway after the optic nerve:

  1️⃣ Optic nerve transmits signals

  2️⃣ Signals reach LGN in thalamus

  3️⃣ Signals are relayed to Area V1
• What is the first brain area that receives neural impulses from the optic nerve?

  Lateral geniculate nucleus
• Match the factor with its definition for object recognition:

  Feature Detectors ↔️ Neurons that respond to specific features

  Perceptual Constancy ↔️ Perception remains constant despite changes

  Perceptual Organization ↔️ Grouping features to create objects
• What are the visual cues used for depth perception?

  Binocular and monocular cues
• What type of motion is perceived when alternating signals appear rapidly in different locations?

  Apparent motion
• Which sensory system demonstrates the highest spatial acuity?

  Visual system
• What study demonstrated inattentional blindness by asking participants to count basketball passes?

  Switcheroo study
• What does the dorsal stream in the visual pathway process?

  Spatial information

  
• What is the term shown in the image for the difference in images seen by each eye?

  Binocular disparity
