Question | Answer |

General Cognitive Functions (5) | Perceiving -> Remembering -> Understanding -> Judging -> Reasoning |
Perceiving | Noticing something with your senses (information from the outer world) - Related to attention |
Remembering | Storing information gathered through perception - Memory |
Understanding | to know the meaning of information |
Judging | to form an opinion about the correctness of information |
Reasoning | to do something with the information (e.g., make an argument) |
Extralinguistic cognitive domains (3) | Attention, memory, executive function. |
Attention (4 types) | Ability to focus on stimulus: sustained (over a period), selective (filtering competing), divided (more than one at once), alternating |
Memory (3 types) | The storage of information. 1) Working memory = space for manipulation. 2) Short-term memory = time in seconds. 3) Long-term memory |
Types of long-term memory | 1) Declarative (Medial temporal lobe and diencephalon): episodic & semantic. 2) Non-declarative (basal ganglia): procedural |
4 Rules of Memory | 1-You cannot remember what you do not pay attention to. 2-You cannot remember (long term) what you do not understand. 3-You must practice memory (e.g., practicing piano). 4-You must actively manipulate memory to store it. |
Internal Memory Strategies (5) | 1-Repetition (neuroplasticity – repetition matters!) 2-Visualization (visualize notes; turn info into story) 3-Association (mnemonics) 4-Grouping (place like items together) 5-Writing it down (physical writing improves memory) |
External Memory Strategies (5) | 1-Calendars 2-To do lists 3-Journals 4-Electronic organization 5-Electronic reminders |
Executive Functions | ... order and manage all other cognitive functions (e.g., attention, memory) for the purpose of setting and attaining goals |
