Although source monitoring may help individuals to more accurately evaluate the credibility of information and the source it came from, source monitoring is unlikely to be an effective means for dispelling false beliefs. Recalling the source of information every time one accesses knowledge is cognitively inefficient and unlikely to be consistently practiced. Additionally, a person's judgment regarding the credibility of a source may be inaccurate.

Source monitoring as a method for combating false beliefs 

When an individual is shown fact-checked information that has been labeled false but later only recalls the misinformation, forgetting the origin of the information and that it had been labeled false. This deficit occurs more often in older adults.

Source Memory Deficit

Where a memory came from can be mixed up (misidentified; misattributed). For example someone can remember hearing about an event from the news when they actually heard it from a friend.

Source-monitoring error (source misattribution)

The process of trying to find the origins of a memory, belief, or knowledge. For example you may be trying to determine whether it was from a friend, a book, or news story.

Focuses of Research on Memory

The recipient of a message forgets the source of the message quicker than they forget the content of the message. This is thought to be especially apparent when the message is persuasive but the source isn't perceived as reliable.

Forgetting is defined as the loss of information from long-term memory. This is a universal human experience, manifesting in everyday situations like forgetting a name, a birthday, or the location of personal items like car keys. Such memory failures, while common, can be a source of frustration and embarrassment, underscoring the fragile nature of human memory.

Levels of output for memory

A central question within the realm of memory research is whether retaining information over short periods of time versus longer periods of time (whether minutes or weeks) is different. In 1890, William James distinguished “primary memory,” composed of past experiences that are active within consciousness, from “secondary memory,” composed of experiences that are not stored at the conscious level but can be recalled. James believed there to be limits to how much information is available in primary memory. Research has generally demonstrated that 7 ± 2 items can be stored at once in a person’s mind, but also that “recoding” items using past knowledge (for example, breaking longer strings into smaller recognizable pieces) can increase memory capacity.

Primary vs. Secondary Memories

While the implicit/explicit, semantic/episodic, and familiarity/recollection distinctions are founded partly on subjective experience, other researchers have instead explored what types of information promote learning retention.

Distinction Between Types of Information Supporting Memory

After being exposed to a stimuli, subjects are asked to report back what they observed.

Recall

Small units (i.e. words, actions) can be grouped together based on associations to form larger units that are easy to remember.

Chunking

Memory depends on the depth of processing information (how much meaning) that occurs. 

Levels of Processing theory

- The Modal Model
- Baddeley & Hitch's Working Memory Model

Memory models

Among many theories, there is consensus surrounding the understanding that medial temporal lobe damage only harms certain types of memory and learning, leaving repetition priming, classical conditioning, and reinforcement-learning largely untouched. Many models also agree about organization of the medial temporal lobe.

Consensus About the Medial Temporal Lobe Among Memory Theories

Source monitoring

It is the mechanism through which the structure of the brain is "shaped" by environments to better perceive environments.

Experience-dependent plasticity 

- Brain damage
- Evolution (errors seen in the general population)

Causes of memory errors and impairment

A learning task that requires a considerable but desirable amount of effort, thereby improving long-term performance.

Examples:

- Interleaving Materials
- Spacing Studying
- Generation Effect
- Retrieval practice (testing)
- Varying Study Conditions

Desirable Difficulties

In neutral emotional circumstances, confidence in the memory and accuracy have a positive relationship. However, in an angry emotional state, the confidence-accuracy relationship becomes negative (as people become more confident, it is predicted that their accuracy will decrease).

The Confidence-accuracy relationship

Prospective memory is the term for the type of memory associated with forward-thinking, initiation of planned events, & retention. Retrospective memory is attributed to one's ability to recall experiences and their contexts (i.e. episodic) in hindsight. It most critically plays a role in remembering events or ideas from the past.

Prospective vs. Retrospective Memory

Memories are a reconstructive process, meaning they are not some recordings of past experiences, but a recreation influenced by the present. They comprised of what happened in events and prior knowledge, expectations, and experiences. This contrasts with what some may think about memories being solely representations of events.

Constructive Nature of Memory

- Proactive interference
- Retroactive interference

Types of Memory Interference

Despite the known fragility of human memory, the legal system, including police, prosecutors, and courts, often depends heavily on eyewitness testimony for criminal prosecutions. This reliance is problematic because memory is a reconstructive process, making eyewitness accounts susceptible to errors that can lead to faulty identifications and, ultimately, wrongful convictions.
