Component 3: Autistic spectrum behaviours — Eduqas A-Level Psychology

Component 3 Autistic Spectrum Behaviours covers clinical manifestations, psychological frameworks, and real-world interventions for autism spectrum conditions. Students explore diagnostic criteria alongside biological explanations (such as genetics, neuroanatomy, and foetal testosterone) and cognitive theories including Theory of Mind and Weak Central Coherence.

This topic encourages students to critically evaluate psychological evidence and consider real-world applications. It bridges cognitive neuroscience and developmental psychology, challenging learners to examine therapies such as Applied Behaviour Analysis (ABA) and the Picture Exchange Communication System (PECS) through clinical, methodological, and ethical lenses.

• →DSM-5 Dyad of Impairments: Persistent deficits in social communication/interaction and restricted, repetitive patterns of behaviour, interests, or activities.
• →Theory of Mind (ToM) and Mind-blindness: The cognitive inability to attribute mental states (beliefs, intents, desires, emotions, knowledge) to oneself and others, evaluated via false-belief tasks.
• →Weak Central Coherence (WCC): Frith's theory proposing a perceptual-cognitive processing style biased toward local, featural details rather than global contextual integration.
• →Extreme Male Brain (EMB) Theory: Baron-Cohen's model contrasting empathising (E) and systemising (S) quotients, mediated by prenatal testosterone exposure.
• →Behaviour Modification Techniques: Interventions including Applied Behaviour Analysis (ABA) based on operant conditioning and Picture Exchange Communication System (PECS) for functional alternative communication.

• Outlines amygdala dysfunction as a biological explanation, linking atypical amygdala function to differences in emotion processing or social responding.
• Explains the chloride-ion account by describing how the direction of chloride flow in early development affects GABA function and neural development.
• Describes genetic predisposition using evidence such as higher concordance in identical than non-identical twins and multiple genes of small effect.
• Links each named explanation to a specific feature of autistic spectrum behaviour rather than leaving the mechanism unconnected.
• Supplies at least two distinct biological explanations as the specification requires.
• Identifies at least two individual differences explanations from gender differences, theory of mind and weak central coherence theory
• Explains theory of mind as difficulty attributing mental states such as beliefs and intentions to others
• Explains weak central coherence as a bias toward local detail processing rather than global, gist-based integration
• Distinguishes an individual differences explanation from a social psychological explanation by locating the cause within the person
• Links each explanation to a plausible source of evidence such as false-belief tasks or detail-focused processing tasks
• Acknowledges that the named explanations are complementary rather than mutually exclusive
• Identifies at least two social psychological explanations from male behaviour, empathising-systemising theory and refrigerator mother
• Explains male behaviour as a social and cognitive style linked to male-typical interaction patterns
• Explains empathising-systemising theory as a profile of relatively lower empathising and relatively higher systemising
• Describes the refrigerator mother account as a historical environmental claim that is now rejected
• Evaluates the refrigerator mother account critically, noting the distress it caused to parents
• Distinguishes social psychological explanations from individual differences explanations by locating the cause in social environment or interaction
• Identifies PECS as a visual picture-exchange approach that teaches functional communication by having the learner hand a picture card to a partner to obtain a desired item.
• Describes RDI as a parent-delivered, relationship-based programme that scaffolds dynamic intelligence and social collaboration through guided activities.
• States a specific behaviour each method aims to modify, such as initiating communication for PECS or shared social relating for RDI.
• Distinguishes the two methods by mechanism, contrasting an external picture-exchange system with guided parent-child social routines.
• Supplies an evaluative point, such as the evidence base or the demand placed on consistent adult delivery, to discriminate between close options.

• 💡For each explanation, write the mechanism, the link to behaviour and one limitation in that order.
• 💡Use twin concordance figures carefully, noting that identical twins share more genes than non-identical twins.
• 💡Keep the chloride-ion account tied to early development rather than to adult GABA function.
• 💡Read the stem carefully to check whether it asks for one explanation or at least two before selecting
• 💡Eliminate options that describe social or environmental causes when the stem asks for individual differences
• 💡Justify your choice by matching the option to the defining feature of the named theory
• 💡Check whether the stem asks for a social psychological explanation and reject options that describe individual cognition only
• 💡Eliminate options that present discredited claims as established causes
• 💡Match the option to the defining feature of the named theory before selecting
• 💡Learn each method as aim, procedure and evaluation so any multiple-choice stem about purpose or delivery can be answered quickly.
• 💡Use the distinctive mechanism of each method to eliminate distractors, for example picture exchange versus guided social routines.
• 💡Check whether a question asks what a method targets rather than how it is delivered, because the two answers differ.
• 💡Always distinguish between cognitive empathy (perspective-taking) and affective empathy when discussing Baron-Cohen's Empathising-Systemising (E-S) theory.
• 💡Use accurate methodological terminology when evaluating core studies (e.g. mention control groups like neurotypical children and individuals with Down's syndrome in Baron-Cohen's 1985 Sally-Anne experiment).
• 💡Integrate contemporary neurodiversity viewpoints alongside classical clinical models to demonstrate sophisticated, top-band evaluative depth in 10-mark and 15-mark essay questions.

• Treats genetic predisposition as a single gene; correct this by describing multiple genes each of small effect alongside environmental interaction.
• States that chloride ions always inhibit neurons; correct this by explaining that early in development the flow direction differs, altering GABA's effect.
• Gives only one explanation when at least two are required; add a second named explanation with its mechanism.
• Confuses weak central coherence with a general memory deficit; keep the focus on local versus global processing
• Treats theory of mind as a single test score rather than a proposed cognitive mechanism; describe the underlying reasoning
• Offers only one explanation when the statement requires at least two; name and explain a second
• Presents the refrigerator mother account as a current accepted explanation; identify it as a discredited historical claim
• Confuses empathising-systemising theory with a claim that all autistic people are male; keep the focus on cognitive style
• Offers only one explanation when the statement requires at least two; name and explain a second
• Confuses PECS with a speech-generating device; keep PECS as a picture-card exchange system in which the learner physically hands over a card.
• Treats RDI as a classroom behaviour-reward scheme; describe RDI as parent-led guided social activities that build dynamic intelligence.
• Names only one method when the criterion requires at least two; always supply both PECS and RDI with a distinct purpose for each.
• Believing Theory of Mind and empathy are identical; ToM relates to cognitive perspective-taking (understanding what someone thinks/knows), whereas affective empathy relates to feeling emotional resonance with another's state.
• Assuming biological explanations argue for a single 'autism gene'; ASD is polygenic and heterogeneous, involving complex interactions across hundreds of rare and common genetic variants.
• Viewing interventions like ABA and PECS as attempts to 'cure' autism; contemporary frameworks focus on functional skill-building, communication facilitation, and reducing distress rather than eradicating neurodivergence.
