Conformity and Asch

Compliance and internalisation

Learn this

External approval versus acceptance consistent with personal values

Public agreement alone does not identify private acceptance.

Normative and informational influence

Learn this

Social acceptance versus evidence about reality

Both motives can contribute in the same situation.

Situations and obedience

Whose proximity changed?

Learn this

Authority ↔ participant. Participant ↔ learner.

A change in the authority’s distance and a change in the learner’s distance are separate manipulations.

Keep the comparison and outcome clear

Learn this

A feature present in one baseline does not establish its effect.

A controlled comparison must vary that feature. Field-request compliance and harmful-task continuation are different outcomes.

Authority and agency

Agentic and autonomous states

Learn this

Milgram’s agentic account: carrying out an authority’s wishes with reduced felt responsibility.

Autonomous: consciously directing one’s own behaviour. Following an instruction alone does not identify the state; distress can coexist with obedience.

Authority regarded as legitimate

Learn this

A recognised right to direct, based on a role or position.

Recognition of authority and felt personal responsibility are separate questions. A clothing effect alone does not measure the proposed psychological mechanism.

Authoritarian personality

Three historical dimensions

Learn this

Submission: deference. Aggression: punitive hostility. Conventionalism: rigid values.

Submission concerns idealised ingroup authorities; aggression concerns perceived conventional-value violators. These constructs do not provide a clinical diagnosis.

Keep measure and design clear

Learn this

Attitude response ≠ observed task behaviour ≠ demonstrated cause.

Identify how participants were selected, what was measured and when. Later questionnaires and selected groups do not randomly assign personality.

Resisting social pressure

Support and its outcome

Learn this

Asch (1955): a correct partner reduced errors. Milgram (1965): after peers refused, most participants defied.

These are different research tasks. Reduced errors or refusal do not directly measure a change in control expectations.

Perceived control

Learn this

Internal: personal action. External: chance or powerful others.

These are positions on a continuum. Specific expectations and valued outcomes matter; a single refusal does not identify a fixed type.

Minority influence

Three advocacy features

Learn this

Consistency: coherence. Commitment: investment. Flexibility: openness.

A central position can be maintained while other arguments are acknowledged. Personal sacrifice does not by itself establish that the position is correct.

Distinguish the outcomes

Learn this

Public matching ≠ private adoption ≠ sustained social change.

Measure each outcome and its timescale. A brief individual answer does not establish lasting shared changes.

The multi-store model

Three memory properties

Learn this

Encoding: form; capacity: amount; duration: persistence

Keep the property measured separate from the task used to measure it.

Transfer and retrieval

Learn this

Copy into longer-term storage; access retained information

Transfer does not require erasing the earlier copy.

The working memory model

Executive control

Learn this

Focus, divide and switch attention

An attentional controller rather than a dedicated content store.

Episodic buffer

Learn this

Limited temporary store for integrated multidimensional information

Links subsystems, perception and long-term information.

Interference and forgetting

Interference direction

Learn this

Earlier → newer target: proactive; later → earlier target: retroactive

Identify the tested target before naming the effect.

Competing access

Learn this

Reduced recall need not mean erased storage

Shared cues with changed responses can create associative competition.

Retrieval cues

Context matching

Learn this

In Godden and Baddeley (1975), word recall was better when learning and test environments matched

Matching differs from a general advantage of either location.

Storage and access

Learn this

A retained target can be temporarily difficult to retrieve

Useful contextual features can support access.

Eyewitness accuracy

Agreement and independence

Learn this

Matching reports may share post-event information

Trace the source of the detail rather than counting agreement alone.

Reports and memory mechanisms

Learn this

A changed report does not uniquely identify an altered trace

Separate observed errors from explanations of how they arose.

The cognitive interview

Report remembered information

Learn this

Report remembered partial detail; do not guess; say when you do not know

Changing perspective is not permission to invent unseen content.

Separate interview outcomes

Learn this

Correct, incorrect and confabulated details are distinct

A larger correct count does not itself establish a higher accuracy proportion.

Animal attachment research

Imprinting and inference

Learn this

Early encounter → following target

Lorenz (1937): bird following could be directed towards a human encountered early. Similar outward behaviour does not establish identical human attachment mechanisms.

Contact comfort

Learn this

Contact preference can differ from feeding source

Harlow (1958): cloth contact despite wire feeding challenges a feeding-only account in the surrogate study. Animal welfare and human generalisation need separate evaluation.

Attachment explanations

Learning explanations

Learn this

Food: primary; caregiver: acquired secondary value

In the feeding account discussed by Bowlby (1958), food is unconditioned and a paired, initially neutral caregiver becomes conditioned. Operant reinforcement changes later responding through consequences.

Bowlby’s attachment concepts

Learn this

Monotropy and working models

Bowlby (1958) emphasised a preferred protective figure; Ainsworth (1979) described expectations of availability. APA distinguishes nonrecurring critical opportunities from sensitive periods with harder later acquisition.

The Strange Situation

Secure base and reunion

Learn this

Available caregiver → supported exploration

A secure reunion includes seeking or accepting caregiver contact. Separation crying alone does not establish a classification.

Distinguish reunion patterns

Learn this

Avoidance ≠ seeking contact while resisting it

Avoidant and resistant patterns describe different organisations of behaviour. Neither is a psychiatric diagnosis or proof of no bond.

Culture and attachment

Local variation matters

Learn this

Country average ≠ every local sample

In van IJzendoorn and Kroonenberg (1988), average within-country variation exceeded average between-country variation. This is an average comparison, not a rule for every pair.

Comparison and cultural meaning

Learn this

Same procedure ≠ proven same meaning

Standardisation helps comparison. Equivalent meaning and representative sampling still need evidence; national labels are not genetic explanations.

Maternal deprivation

Separation and deprivation

Learn this

Time apart ≠ insufficient emotional care

A familiar responsive substitute can sustain affectionate care. Biological parenthood and physical co-residence do not alone measure care quality.

Historical theory and evidence

Learn this

Retrospective association ≠ isolated cause

Interpret proposed risks alongside confounding, care quality, recovery and individual variation. A group pattern is not an individual prognosis.

Institutional care and adoption

Recovery and persistent risk

Learn this

One outcome can recover while another remains elevated

Sonuga-Barke et al. (2017): substantial cognitive recovery coexisted with elevated autism-spectrum symptoms, disinhibited social engagement and inattention/overactivity. Group risks allowed individual variation.

Natural longitudinal evidence

Learn this

Follow-up ≠ random exposure allocation

The English and Romanian Adoptees project followed Romanian and UK adoptees: a longitudinal natural experiment, not assigned deprivation. Sonuga-Barke et al. (2017) requires considering overlapping timing/duration, prior influences and selective attrition.

Attachment across relationships

Continuity and change

Learn this

Earlier experience → expectations that can be revised

Working models concern self and others. They can inform later relationships without determining a partner’s response. Early influence and later change can coexist.

Adult reports and infant attachment

Learn this

Adult self-description ≠ direct infant observation

Self-selection and retrospective recall limit representativeness and causal interpretation. Matching category names does not provide an observed infant history.

Defining mental health

Different questions

Learn this

Frequency / norms / functioning / positive ideals

Identify which perspective supplies a judgment before evaluating its limits.

A definition needs interpretation

Learn this

Specify population, context and decision rule

Rarity is not a value judgment, social conformity is not complete well-being, and practical difficulty does not identify its cause.

Phobias and learning

Acquisition and maintenance

Learn this

Classical cue pairing / operant consequences

In the two-process account, fear can be acquired through pairing and avoidance can be strengthened by relief.

Negative reinforcement

Learn this

Aversive experience reduced → response strengthened

Negative does not mean that the response is weakened. Persistent avoidance after fear declines limits a complete fear-reduction account.

Treating phobias

Starting point and pacing

Learn this

Systematic desensitisation: relaxation + graded anxiety hierarchy / Flooding: direct high intensity

The procedural contrast does not itself establish comparative efficacy.

Consent and evaluation

Learn this

Voluntary, informed and with capacity

Compare symptom outcomes and acceptability while keeping valid consent as a distinct requirement.

Depression and cognition

Cognitive-triad contents

Learn this

Self / personal world / future

These are contents of negative views, rather than the A, B and C roles in a different framework.

ABC roles

Learn this

Activating event / beliefs / emotional and behavioural consequences

Beliefs contribute to responses while events remain part of an interacting account. A rigid demand is different from a flexible preference.

CBT for depression

Cognitive and behavioural work

Learn this

Examine evidence / consider alternatives / practise changes

CBT combines collaborative discussion with applying skills beyond sessions; completing a process is different from measuring its outcome.

Benefit and suitability

Learn this

Comparator, quality and individual assessment

Adult pooled efficacy informs a question about average benefit. It does not establish equivalence with other treatments, a personal guarantee or suitability without assessment.

OCD and biological treatment

Obsessions and compulsions

Learn this

Unwanted intrusion → distress → repetitive act or mental ritual

Compulsions may briefly ease distress. Examples illustrate features rather than establish a diagnosis.

SSRI action and inference

Learn this

Inhibit serotonin reuptake

Treatment benefit does not establish a primary serotonin deficit as the cause of OCD.
