Memory encoding is a process where sensory information is transformed into a form that can be stored and later retrieved.
Some information enters memory automatically, while other types require effort to encode.
Focus of discussion: effortful encoding processes include paying attention, deep processing, elaboration, and the use of mental imagery.
Attention in Memory Encoding
Attention is a crucial prerequisite for encoding information into memory.
Selective Attention: (Miller & Unsworth, 2021) Focusing on one specific aspect of experience while ignoring others. For example, during a romantic date, you might not notice a loud bus passing by.
Divided Attention: Concentrating on multiple activities simultaneously (Green et al., 2021), such as checking your phone while reading.
Sustained Attention (Vigilance): Maintaining attention on a single stimulus over a prolonged period (Marty Douglas et al., 2021; Weiner et al., 2018).
Example: Focused studying for an exam.
Importance of attention in encoding:
Multitasking: Involves dividing attention, often detrimental to memory. Students frequently multitask by combining homework, messaging, and social media. This can interfere with encoding (Patillo, 2010).
Levels of Processing
Levels of Processing Theory (Fergus Craik & Robert Lockhart, 1972): Memory retention depends on the depth at which information is processed.
Shallow Processing: Involves processing superficial characteristics (e.g., shapes of letters).
Intermediate Processing: Involves labeling or reading the information without deeper understanding (e.g., just reading the word "mom").
Deep Processing: Involves thinking about the meaning and significance (e.g., recalling personal memories associated with the word "mom").
The deeper the processing, the better the memory retention (Alexander, 2018).
Example: Associating a mother's attributes or feelings helps in better recalling the term "mom."
Influence of Technology on Encoding
The use of laptops and tablets can impede learning and memory by distracting attention.
Studies show that taking notes by hand outperforms typing in terms of memory retention (Mueller & Oppenheimer, 2014).
Elaboration: Involves forming numerous connections around a stimulus, enhancing memory encoding.
When elaborating, we create extensive networks of associations, which can occur at all processing levels.
Examples of elaboration:
Shallow Level: Thinking of letter shapes when encoding "mom."
Deep Level: Reflecting on personal experiences of various mothers.
Effective elaboration enhances memory paths for future retrieval.
Self-Referencing: Relating new information to personal experiences bolsters memory retention (Duchess & Kensinger, 2018).
Neuroscience studies confirm that elaboration during encoding is linked to increased brain activity in regions like the left frontal lobe and hippocampus (Barge et al., 2018; Frank & Kopkas, 2021).
Mental Imagery as a Tool for Memory
Mental Imagery: Conjuring visual images associated with what needs to be remembered significantly aids memory (Bainbridge et al., 2021).
Example: Akira Haraguchi memorized pi to 111,700 decimal places using descriptive imagery.
Everyday applications include:
Servers remembering orders by visualizing customers.
Students associating reading materials with visual elements.
Dual Code Hypothesis: (Alan Paivio, 1971, 1986, 2007) Proposes that memory can be stored as verbal codes or image codes; images enhance memory due to their detailed nature (Paivio & Sadowski, 2011; Van Der Kussen et al., 2021).
The Challenge of Fake News and Memory
Memorable false information (fake news) can pose a significant issue.
Examples of widely shared false claims on social media (e.g., fictional bacon shortage).
Memory and False Information:
At encoding, new information is initially treated as true; later, it may be labeled as false based on familiarity and trusted sources.
Familiarity with false claims can create the illusion of truth (Rashier & March, 2020; Swire et al., 2017).
Cognitive mechanisms behind memory retention for fake news include emotional resonance and misattribution of information context.
Research suggests presenting corrections along with the false information may effectively update knowledge, boosting the depth of processing in the brain (Wolheim et al., 2020).
Conclusion and Key Questions
Effective encoding of information requires cognitive effort and varied strategies (attention, processing depth, elaboration, and imagery).
Key questions for self-reflection and deeper understanding:
What encoding processes require effort?
How do divided and selective attention differ?
What constitutes elaboration and why is it vital for memory?
