Teaching and Learning Final Ch.5
Afferent | Literally, carrying to; describes the part of the PNS that detects changes in the environment and conducts nerve impulses from the sensory receptors to the CNS |
Efferent | Literally, carrying away from; describes the part of the PNS that transmits impulses away from the CNS to the effectors |
Exteroceptors | Receptors located at or near the body’s surface that detect stimuli outside the body and provide information about the environment |
Interoceptors | Receptors that detect stimuli from the internal viscera and provide information about the internal environment |
Proprioceptors | Receptors that provide information regarding body position and movement by detecting changes in muscle tension, joint position, and equilibrium |
Photo receptors | Light-sensitive cells located in the eyes |
Optic chiasm | Point at which some fibers from each of the optic nerves cross, allowing visual signals to be processed by the opposite side of the brain |
Focal system | Visual system that functions o identify objects primarily located in the central region of the visual field |
Ambient system | Visual system that functions at a subconscious level and is thought to be responsible for spatial localization and orientation |
Spotting | Fixating one’s visual attention on a specific spot during rotation of the body in order to reduce dizziness and remain oriented |
Fixating | Focusing visual attention on a specific object |
Optic flow | The perceived visual motion of objects as the observer moves relative to them |
Feedforward | Describes the sending of information ahead of a movement, for advance preparation or adjustments of the movement |
Manual aiming | The act of reaching or transporting the hand to a target location |
Prehension | The action of reaching and grasping |
Proprioception | The continuous flow of sensory information that is received from receptors located in the muscles, tendons, joints, and inner ear regarding movement and body position |
Golgi tendon organs | Proprioceptors located at the junction of a tendon with a muscle that indicate the level of tension development in a tendon |
Muscle spindles | Proprioceptors located between the skeletal muscle fibers in the muscle belly that indicate how much and how fast the muscle’s length is changing |
Joint kinesthetic receptors | Receptors located in and around synovial joints that respond to pressure, acceleration and deceleration, and excessive strain on a joint |
Vestibular apparatus | A collective group of receptor organs in the inner ear that respond to changes in posture and balance |
Reflex | An automatic, involuntary response to stimuli |
Reflex arc | The simplest pathway by which a reflex occurs |
Interneurons | Nerve cell that lies between a sensory and a motor neuron in a reflex arc |
Cerebral cortex | The outermost layer of the cerebrum |
Neural plasticity | The ability of the brain to change its organization and ultimately its function throughout the lifespan |
Cortical remapping | Reorganization of an area(s) in the cortex of the brain resulting in a new cortical map |
Memory | ability to store and recall information |
Sensory memory | memory system that retains a brief impression of a sensory stimulus after the original stimulus has ended, allowing determination of whether or not it demands further attention |
Working memory | A set of interacting information processing components that actively stores and manages information required to carry out complex cognitive tasks |
Phonological loop | memory system responsible for short term storage of spoken and written material |
Visuospatial sketchpad | Memory system responsible for the temporary storage and manipulation of spatial and visual information |
Central executive | Component of working memory that controls the flow of information between the phonological loop and visuospatial sketchpad, regulates information processing, and governs attentional activities |
Long-term memory | Memory characterized as having a seemingly limitless capacity and duration |
Procedural memory | memory of how to perform various skills, operation and actions |
Declarative memory | That portion of our memory used for facts or events; commonly broken down into two types: episodic memory and semantic memory |
Episodic memory | The memory of personal experiences and events that are associated with a specific time and context |
Semantic memory | The memory of general knowledge that is developed through experiences but is not associated with time |
Proactive Interference | interference of old memories with the retention of new ones |
Retro-active interference | interference of new learning with the retention of older memories |
