‭Classical conditioning‬ ‭-‬ ‭Definition: a type of learning where a neural stimulus becomes associated with an‬ ‭unconditioned stimulus to elicit a conditioned response‬ ‭-‬ ‭Unconditioned Response (UR): a natural unlearned reaction to an unconditioned‬ ‭stimulus → e.g. salivating when hearing food is in your mouth‬ ‭-‬ ‭Unconditioned stimulus (US): a stimulus that naturally triggers an unconditioned‬ ‭response without any prior learning. → e.g. the food that makes the dog salivate‬ ‭-‬ ‭Conditioned response (CR): a learned response to a previously neutral stimulus, which‬ ‭has become a conditioned stimulus → e.g. salivating when hearing a bell‬ ‭-‬ ‭Conditioned stimulus (CS): a previously neutral stimulus that, after being paired with an‬ ‭unconditioned stimulus, triggers a conditioned response → e.g. the bell‬ ‭-‬ ‭Acquisition: the initial phase where the conditioned stimulus is paired with the‬ ‭unconditioned stimulus to establish a conditioned response‬ ‭-‬ ‭Latent inhibition: the phenomenon where a familiar stimulus takes longer to acquire‬ ‭meaning as a conditioned stimulus than a new stimulus‬ ‭-‬ ‭Renewal: the return of a conditioned response when an organism is placed back into the‬ ‭environment where the conditioning originally occurred, after extinction.‬ ‭-‬ ‭Stimulus generalisation‬ ‭-‬ ‭When a conditioned response is triggered by stimuli similar to the original‬ ‭conditioned stimulus‬ ‭-‬ ‭A dog that salivates to a bell may also salivate to a doorbell, even though its‬ ‭slightly different‬ ‭-‬ ‭Stimulus discrimination‬ ‭-‬ ‭The learned ability to differentiate between the conditioned stimulus and other‬ ‭stimuli that do not predict the unconditioned stimulus‬ ‭-‬ ‭The dog only salivates to a specific bell and not similar sounds‬ ‭-‬ ‭The little albert experiment‬ ‭-‬ ‭CS: baby albert was conditioned to fear a white rat‬ ‭-‬ ‭US: by pairing it with a loud sound‬ ‭-‬ ‭CR: causing Albert to show fear‬ ‭-‬ ‭Albert generalised this fear to other similar stimuli‬ ‭-‬ ‭Shows how emotions like fear can be conditioned‬ ‭-‬ ‭Demonstrates stimulus generalisation‬ ‭Self-prioritisation effect‬ ‭-‬ ‭Definition: refers to the phenomenon where individuals show a preference for processing‬ ‭information related to themselves over information related to others‬ ‭-‬ ‭Evidence: research demonstrates that individuals respond faster and more accurately to‬ ‭stimuli associated with themselves compared to those associated with friends or‬ ‭strangers‬ ‭-‬ ‭Implications: for understanding social cognition and how individuals navigate their social‬ ‭environments. Suggests that self relevance can significantly influence cognitive‬ ‭processing and decision making‬ ‭Self-recognition‬ ‭-‬ ‭ efinition: refers to the ability of an individual to identify themselves as distinct from‬ D ‭others, often assessed through tasks like the mirror test where individuals recognise‬ ‭their reflections as themselves‬ ‭-‬ ‭Importance: considered an indicator of self-awareness and is linked to various cognitive‬ ‭and social abilities. Significant milestone in cognitive development‬ ‭-‬ ‭Debate: some argue that recognising oneself in the mirror does not equate to a deeper‬ ‭understanding of ones identity or existence‬ ‭Decision making and judgement‬ ‭-‬ ‭System 1 based judgement‬ ‭-‬ ‭Fast, automatic and intuitive way of thinking. Operates quickly and with little‬ ‭effort, relying on heuristics‬ ‭-‬ ‭Instinctive‬ ‭-‬ ‭Quick decisions based on limited information‬ ‭-‬ ‭Prone to biases and errors‬ ‭-‬ ‭System 2 based judgment‬ ‭-‬ ‭Reasoning and critical thinking‬ ‭-‬ ‭Difficult or unfamiliar tasks‬ ‭-‬ ‭More accurate, requires cognitive resources‬ ‭-‬ ‭Slower, more deliberate, and analytical way of thinking. Requires conscious effort‬ ‭and used for complex decision making‬ ‭-‬ ‭Prospect theory‬ ‭-‬ ‭Describes how people make decisions under risk and uncertainty‬ ‭-‬ ‭Loss aversion: people tend to prefer avoiding losses over acquiring equivalent‬ ‭gains‬ ‭-‬ ‭Value function: is concave for gains and convex for losses, indicating diminishing‬ ‭sensitivity to changes in wealth‬ ‭-‬ ‭Framing effects: the way choices are presented can significantly influence‬ ‭decision making‬ ‭-‬ ‭Heuristics and Fallacies‬ ‭-‬ ‭Heuristics are mental shortcuts where people judge the likelihood of events‬ ‭based on how easily examples come to mind‬ ‭-‬ ‭Conjunction fallacy: when people assume that specific conditions are more‬ ‭probable than a single general one. E.g. linda example‬ ‭-‬ ‭Availability heuristic: a mental shortcut where people judge the likelihood of‬ ‭events based on how easily examples come to mind. E.g. if someone frequently‬ ‭hears about plane accidents they may overestimate the danger of flying‬ ‭-‬ ‭Adjustments and anchoring‬ ‭-‬ ‭The cognitive bias where individuals rely too heavily on the first piece of‬ ‭information encountered (“the anchor”) when making decisions‬ ‭-‬ ‭Expected utility theory‬ ‭-‬ ‭A normative model that suggests individuals make decisions by considering the‬ ‭expected outcomes and their associated utilities‬ ‭Language‬ ‭-‬ ‭Aphasia‬ ‭-‬ ‭ isorder that affects a person's ability to communicate, typically resulting from‬ D ‭brain damage‬ ‭-‬ ‭Broacas‬ ‭-‬ ‭Difficulty in speech production while comprehension remains intact‬ ‭-‬ ‭Difficulty in speech production‬ ‭-‬ ‭Results from damage to the frontal lobe‬ ‭-‬ ‭Slow, effortful production‬ ‭-‬ ‭Weniche‬ ‭-‬ ‭Fluent but nonsensical speech, significant difficulties in language‬ ‭comprehension‬ ‭-‬ ‭Whorfian hypothesis‬ ‭-‬ ‭The structure and vocabulary of language influence how its speakers perceive‬ ‭and think about the world‬ ‭-‬ ‭Strong: language determines thought‬ ‭-‬ ‭Weak: language influences thought‬ ‭-‬ ‭Associations between language and space‬ ‭-‬ ‭People often associate concrete words with specific spatial locations. E.g. “Attic”‬ ‭may be considered higher, and “basement” linked to lower‬ ‭-‬ ‭Associations between language and colour‬ ‭-‬ ‭Different languages may have varying associations with colours, influencing how‬ ‭speakers perceive and categorise colours.‬ ‭Heyes & Catmur‬ ‭-‬ ‭Mirror neurons‬ ‭-‬ ‭Definition: a class of neurons that fire both when an individual performs an action‬ ‭and when they observe the same action performed by another‬ ‭-‬ ‭Function: they are implicated in low level processing of observed actions‬ ‭-‬ ‭Example: yawning‬ ‭-‬ ‭Action understanding‬ ‭-‬ ‭Role: contribute to understanding others’ actions by providing a direct neural‬ ‭mechanism for recognising and interpreting actions‬ ‭-‬ ‭Limitations: while mirror neurons play a role in basic action understanding, they‬ ‭do not support complex social cognition or abstract reasoning‬ ‭-‬ ‭Autism‬ ‭-‬ ‭Implications: mirror neurons do not play a role in autism. This challenges the‬ ‭notion that deficits in empathy or social understanding in individuals with autism‬ ‭are primarily due to mirror neuron dysfunction‬ ‭-‬ ‭Empathy‬ ‭-‬ ‭Mirror neurons are associated with affective empathy, where observing someone‬ ‭in distress can evoke similar feelings in the observer‬ ‭Operant conditioning‬ ‭-‬ ‭A learning process where behaviour is influenced by the consequences that follow it‬ ‭strengthening behaviours through reinforcement and weakening them through‬ ‭punishment‬ ‭-‬ ‭Positive and negative reinforcement and punishment‬ -‭ ‬ ‭ rimary and secondary reinforcers‬ P ‭-‬ ‭Reinforcement schedules‬ ‭-‬ ‭Partial reinforcement: reinforcing behaviour only some of the time‬ ‭-‬ ‭Effect: slower learning but more resistant to extinction‬ ‭-‬ ‭Fixed ratio: reinforcement after a set number of responses. Example: a coffee‬ ‭shop rewards you with a free coffee after 10 purchases‬ ‭-‬ ‭Fixed interval: reinforcement after a set period, regardless of the number of‬ ‭responses. Example: receiving a paycheck every 2 weeks‬ ‭-‬ ‭Variable ratio: reinforcement after an unpredictable number of responses.‬ ‭Example: slot machines at a casino pay out after a random number of lever pulls‬ ‭-‬ ‭Variable interval: reinforcement after varying time intervals, regardless of the‬ ‭number of responses. Example: checking email, where responses may be‬ ‭rewarded unpredictably with messages.‬ ‭Social condition‬ ‭-‬ ‭The director paradigm‬ ‭-‬ ‭Purpose: assesses ability to recognise and account for another persons‬ ‭viewpoint‬ ‭-‬ ‭Used to:‬ ‭-‬ ‭Study perspective taking and cognitive empathy‬ ‭-‬ ‭Method‬ ‭-‬ ‭“Director” gives instructions about how to arrange objects in a scene but‬ ‭has a different point of view of the scene. Participants must understand‬ ‭the director's perspective to follow instructions correctly.‬ ‭-‬ ‭Affective Empathy‬ ‭-‬ ‭Refers to the ability to respond with an appropriate emotion to others emotional‬ ‭state.
