MEMORY

How do psychologist describe the human memory system?

What information do we encode automatically and what information do we encode effortfully?

How does the brain stores our memories?

*WORKING MEMORY is a system for temporarily storing and managing the information required to carry out complex cognitive tasks such as learning, reasoning, and comprehension. Working memory is involved in the selection, initiation, and termination of information-processing functions such as encoding, storing, and retrieving data.

Information-processing models involve three processes: encoding, storage, and retrieval. ... The human brain processes information on dual tracks, consciously and unconsciously.

Sensory Memory

Sensory memory is the first stage of memory. Its purpose is to give your brain time to process incoming information

Most of the information that gets into sensory memory is forgotten.

Processes information gathered through your five senses. It holds information for an extremely brief of time after the original stimulus has stopped.

Short-Term Memory

Long-Term Memory

You subconsciously and continuously gather information through your five senses

Holds information you are actively thinking about. It lasts for a very brief amount of time and can only hold 7+/- 2 pieces of information at once.

Short term memory holds information temporarily, pending further processing.

Types of Sensory Memory

Iconic Memory is the visual sensory memory that holds the mental representation of your visual stimuli.

Haptic Memory is the tactile sensory memory that holds information from your sense of feeling.

Echoic Memory is the auditory sensory memory that hold information that you hear.

unlike sensory memory which holds the complete image received by your senses, short term memory only stores your interpretation of the image.

Some information retained in short term memory is processed or encoded into long term memory.

Holds information for long periods even permanently. It seemingly can hold an unlimited amount of information.

Information is filed away in your mind and must be retrieved before it can be used.

Some information in your long term memory is easy to recall, while others memories are much more difficult to retrieve.

Types of Long Term Memory

Explicit Memory
are those experiences that can intentionally and consciously remembered.

Episodic Memory refers to the firsthand experiences that you have had.

Semantic Memory refers to knowledge of facts and concepts about the world.

Implicit Memory refers to knowledge that we cannot consciously access. It is remembering without awareness.

Encoding the processing of information into the memory systems.

Storage the retention of encoded information over time.

Retrieval the process of getting information out of memory storage.

Automatic Processing: Unconscious encoding of incidental information such as space, time and frequency and of well-learned information such as word meanings.

Effortful Processing: Encoding that requires attention and conscious effort.

The Strength of the Memory: people can recall stronger memories for a longer period than weaker ones. When it comes to corporate training, the learning content should be highly relevant to each learner and it should have meaning.

Psychologist Karl Lashley (1950) further demonstrate that memories do not reside in single, specific spot.

Amnesia is the loss of memory, those with it can neither remember prior memories and have difficult making new ones.

Memory researchers have searched for a memory trace in searching for the location our various memories.

The prolonged strengthening of potential neural firing is called long-term potentiation (LTP). Provides a neural basis of learning and learning association.

Experiment Associated

The Forgetting Curve shows that learners will forget an average of 90% percent of what they have learned within the first month.

1.Drugs that block LTP with learning

2.Mutant mice engineered to lack an enzyme needed for LTP can't learn their way out of a maze.

A flashbulb memory is a clear memory of an emotionally significant moment or event.

Although this kind of memories is vivid, misinformation can swap into them.

Stress can act like an acid, corroding neural connections and shrinking the brain area ( the hippocampus )that is vital for laying down memories.

When stress hormones are flowing, Older memories may be blocked.

How to counter forgetting curve?

Improve Clarity:
Make the information easier to absorb in the first place. If you learn something from an essay or an article, it’s easier to forget the meaning or miss it entirely. Try to represent your information in a diagram..

Make it More Relevant
An off-the-shelf learning resource won’t have the same impact as a custom-made one. In every piece of training you produce, never forget the core purpose of your organisation. This works in two ways: the more relevant the training, the is easier it is to recall.

Make it More Interactive
People learn better when they’re actively involved than when they’re passive observers. Adding elements of gameplay to the learning is a great way to keep the learner involved and they might even enjoy the training!

Understanding Learning Curve

What is Learning Curve?

The learning curve was first described by psychologist Hermann Ebbinghaus in 1885 and is used as a way to measure production efficiency and to forecast costs.

A learning curve is a concept that graphically depicts the relationship between the cost and output over a defined period of time, normally to represent the repetitive task of an employee or worker.

The learning curve is referred to as the experience curve, the cost curve, the efficiency curve, or the productivity curve.

The learning curve provides measurement and insight into all the above aspects of a company. The idea behind this is that any employee, regardless of position, takes time to learn how to carry out a specific task or duty.

The amount of time needed to produce the associated output is high. Then, as the task is repeated, the employee learns how to complete it quickly, and that reduces the amount of time needed for a unit of output.

Benefits of using the Learning Curve

Companies know how much an employee earns per hour and can derive the cost of producing a single unit of output based on the number of hours needed.

A well-placed employee who is set up for success should decrease the company's costs per unit of output over time.

Businesses can use the learning curve to conduct production planning, cost forecasting, and logistics schedules.
