Study Notes

Working Memory

Working memory is the short-term retention of information while simultaneously processing other information.
It is the ability to control and regulate attention to achieve goals, particularly while navigating distracting information.
Alan Baddeley proposed influential models of working memory, all featuring key distinctions:
- Central Executive: Coordinates information from "slave" systems.
- Visuospatial Sketchpad (Visual): Processes visual images, connected to perception and action.
- Phonological Loop (Audio): Stores and rehearses speech-based information, closely tied to language.
The Central Executive is crucial for coordinating and manipulating information, while the other systems primarily store information, relaying it back to the central executive.
Evidence for separate stores:
- People struggle to remember similar-sounding letters more than different-sounding letters, illustrating the importance of phonemes in the phonological loop.
- Chess players' decisions and board memory are more affected by visuospatial load than verbal load, indicating distinct storage for visual and verbal information.

Memory Capacity Measurement

Working memory capacity is assessed using various tasks, such as:
- Digit Span: Remembering a sequence of digits in order.
- Reading Span: Remembering a set of words while reading sentences.
- Operation Span: Combining arithmetic problems with remembering words.

Memory Types

Memory encompasses all knowledge, including personal identity, past experiences, language skills, and learned behaviors.
It is a complex process influenced by various contextual and individual factors.
Retrospective Memory: Remembering past events (e.g., what you had for breakfast yesterday).
Prospective Memory: Remembering to perform future tasks (e.g., buying milk after work).
Declarative Memory (Explicit):
- Semantic Memory (Knowing): Memory for facts (e.g., who is the PM of Australia).
- Episodic Memory (Remembering): Memory for events (e.g., your tenth birthday).
Non-Declarative Memory (Implicit):
- Procedural Learning: Memory for actions and skills (e.g., kicking a football).

Heuristics and Biases

Representativeness Heuristic: Judging the likelihood of something based on how well it fits a stereotype or prototype.
Base Rate Neglect: Ignoring the overall frequency of events when making judgments, focusing more on individual characteristics.
Availability Heuristic: Judging the probability of an event based on how easily examples come to mind.
Anchoring and Adjustment: Starting with an initial estimate (anchor) and adjusting it insufficiently based on new information.
Conjunction Fallacy: Mistakenly believing that a conjunction of events is more likely than one of the events alone.

Prospect Theory

Expected Utility Theory: A rational model suggesting people make decisions based on maximizing expected value.
Prospect Theory: A descriptive model emphasizing the actual decision-making process, highlighting deviations from rational choice.
Key Features of Prospect Theory:
- Loss Aversion: Losses are experienced more strongly than equivalent gains.
- Framing Effects: The way a choice is presented can influence decisions, even if the underlying outcomes are the same.
- Reference Point: People assess gains and losses relative to a reference point.

Mirror Neurons and Empathy

Mirror neurons fire both when performing an action and when observing someone else perform that action, potentially reflecting an understanding of another person's actions.
Mirror neurons may be associated with affective empathy (sharing another person's emotions).
However, they do not fully explain cognitive empathy (understanding another person's mental states) or empathic concern (a broader desire for another's well-being).
The brain is a complex network shaped by learning, not a fixed set of functions associated with specific brain parts.

Critiques of the Restrictive Isomorphic Hypothesis (RIM)

RIM argues that experiencing empathy requires mirroring another person's emotional state.
This argument oversimplifies empathy, failing to account for cognitive empathy and empathic concern.
For instance, a psychologist experiencing a client's grief may not feel grief themselves, but they might experience concern for their client's well-being.
This concern emphasizes empathic concern rather than direct emotional mirroring.
