Study Notes

Sensory Systems

  • Sensory receptors in the ear detect sound waves and convert them into neural signals.
  • The eye detects light, which is a form of electromagnetic energy.
  • The main function of vision is to detect and interpret light from the environment.
  • The minimum amount of energy required for activation of sensory systems is called the absolute threshold.

Weber's Law

  • According to Weber's Law, the fraction of the original stimulus intensity that is just noticeable is different for different senses.
  • The minimum difference in stimulation that is just noticeable is called the just-noticeable difference (JND).

Color Vision

  • The detection of color allows for the perception of different wavelengths of light.
  • The two types of photoreceptors found in the human eye are rods and cones.
  • Cones are found in the center of the retina and are sensitive to fine detail and color.
  • The trichromatic theory of color vision explains color as the differential activation of three color elements in the eye.
  • The three dimensions of color perception are hue, saturation, and brightness.
  • The term for the intensity of a color is saturation.

Taste and Smell

  • The primary tastes are sweet, sour, salty, and bitter.
  • Taste receptors are found on the tongue and respond to different chemical properties of food.

Pain and Touch

  • The term for the source of information that relates to tissue destruction and motivates behaviors to terminate the source of pain is nociception.
  • The term for the detection of physical stimuli in the outside world by receptors in the skin is tactition.
  • There are three classes of skin receptors: mechanoreceptors, thermoreceptors, and nociceptors.

Learning Theories

  • The term for the selection, organization, and interpretation of sensory input is perception.
  • According to classical conditioning, a response that is reliably elicited by a stimulus is called a conditioned response.
  • The term for the neutral stimulus that is paired with the unconditioned stimulus in classical conditioning is the conditioned stimulus (CS).
  • The term for the response that resembles the unconditioned response and is elicited by the conditioned stimulus is the conditioned response (CR).
  • The term for the process by which the presentation of a stimulus after a response makes the response more likely to occur in the future is reinforcement.
  • The term for the termination of an aversive event that makes a behavior more likely to occur in the future is negative reinforcement.
  • The term for the situation in which a response that terminates an aversive stimulus will strengthen that response is escape learning.
  • The term for the decrease in the likelihood that a response will occur due to the presentation of an aversive stimulus is punishment.
  • According to Bandura's Social Learning Theory, learning through observation of others is called modeling.
  • The term for the reemergence of a previously extinguished conditioned response is spontaneous recovery.
