Question Answer
Memory The Capacity - How much can be held in the memory. Coding (or encoding) - the way information is changed so that it can be held in the memory. This could be acoustic - a song, or visual - an image. Duration - How long a memory lasts before it is forgotten.
Types of encoding Visual - images, e .g to remember a persons face. Acoustic - sounds, e . g to remember a song. Semantic - meanings, e . g to remember what a word means.
Short Term Memory (STM) Some times described as "working memory". The short term memory is for immediate events. It can be described as temporary storage. Items held in the STM tend to disappear (be forgotten) unless rehearsed/repeated. Most information taken into the STM is encoded acoustically. The capacity is ~7+/-2. As humans, we chunk together infomation so we can remember more. The duration is arguable, though most say it is less than 18 seconds.
Long Term Memory (LTM) Memory for past events. Can last from 2 minutes to 100 years. It is mostly coded semantically. The duration is said to be potentially unlimited. This also is the same for the capacity.
Cognitive Mind major influence on behaviour how we perceive/interpret information is important some fear spiders, some don't.
Social people major influence on behaviour. we are influenced by individuals, groups culture, and society. People tend to obsess over others interpretations of themselves.
Biological biological processes and genetic make up determine our behaviour, chemical imbalances and brain abnormalities influence our actions.
Learning environmental shapes our behavior, how we learn, reinforcement and punishment. if we are punished, we will be less likely to repeat the action. if we are reinforced, we will repeat the action.
Psycho dynamic approach emotional aspects of peoples lives, childhood experience - unconscious thoughts are important, id/ego/superego unconscious thoughts are important.
The Nervous System The human nervous system is a complex network of nerve cells that carry messages to and from the brain and spinal cord to different parts of the body and so helps all the parts of the body to communicate with each other. Controlling the nervous system is the brain, the powerhouse of the body, even though it only takes up about 2% of the body's weight. It has billions of neural cross-connections.
Central Nervous System Consists of -Brain Spinal Cord
Peripheral nervous system consists of -somatic nervous system -autonomic nervous system the autonomic consists of -sympathetic and parasympathetic nervous systems
Sympathetic Nervous System The SNS is involved in emergency responses (fight or flight response). The SNS increases heart rate and blood pressure. All of these factor in to help our survival.
Parasympathetic nervous system Parasympathetic does the opposite of the SNS, relaxing the individual after SNS activation.
