Parietal lobes | Area of the cortex that include the sites in which body sensations register. |
Corpus callosum | Thick band of axon fibers connecting the cerebral hemispheres. |
Occipital lobe | Portion of the cerebral cortex in which vision registers in the brain. |
Frontal lobes | Areas of the cortex associated with movement,the sense of self, and higher mental functions. |
Left hemisphere | Language, speech, writing (small details) |
Right hemisphere | Spatial skills, visualization, pattern recognition (overall patterns) |
Hindbrain structure | Contains the medulla, cerebellum, and reticular formation. |
Medulla | The structure that connects the brain with the spinal cord and controls vital life functions. |
Reticular formation (RF) | A network within the medulla and brainstem; associated with attention, alertness, and some reflexes. |
Limbic system | A system in the forebrain that is closely linked with emotional response. |

Transformation | Mental ability to change the shape or form of a substance (such as clay or water) and perceive it as the volume staying the same. |
Egocentric thought | Thought that is self-centered and fails to consider the viewpoints of others. |
Scaffolding | Process of adjusting instruction so that it is responsive to a beginner's behavior and supports the beginner's efforts to understand a problem or gain a mental skill. |

Memory | Active mental system for receiving, encoding, storing, organizing, altering, and retrieving information. |
Sensory memory | The first, normally unconscious, stage of memory, which holds an exact record of incoming information for a few seconds or less. |
Maintenance rehearsal | Silently repeating or mentally reviewing information to hold it in short-term memory. |

Memory decay | Fading or weakening of memories |
Forgetting | Could be from disuse |
Cue dependent | Stimuli associated memory-a cue is needed to retrieve the memory |
State dependent learning | Memory influenced by one's physical state at the time of learning and at the time or retrieval. Improved memory occurs when the two states match. |
