Self-Referential Encoding Task

HED task ID: hedtsk_self_referential_encoding

Family: Memory control and prospective memory tasks

Also known as: SRET, Self-Reference Effect Paradigm, Self-Referential Processing Task, Trait Adjective Endorsement Task

Participants judge whether trait adjectives describe themselves vs. another person or a semantic property; the self-reference effect (superior recall for self-encoded items) and endorsement patterns index self-concept and self-referential processing.

Description

The Self-Referential Encoding Task exploits the robust finding that information encoded in relation to the self is remembered better than information encoded in other ways (the self-reference effect; Rogers, Kuiper, & Kirker, 1977). In the standard paradigm, participants view trait adjectives and make judgments under different encoding conditions: ‘Does this word describe you?’ (self-reference), ‘Does this word describe [other person]?’ (other-reference), ‘Is this a positive word?’ (semantic), or ‘Is this word in uppercase?’ (structural). A surprise recall or recognition test follows. The self-reference effect is the recall advantage for self-encoded items over semantic or other-reference conditions. Beyond the memory effect, the pattern of adjective endorsement (which traits are endorsed as self-descriptive) provides a direct window into self-concept content. This has made the task central to depression research: depressed individuals endorse more negative and fewer positive adjectives as self-descriptive, and show reduced or reversed self-reference memory effects for positive material. The paradigm engages cortical midline structures (medial prefrontal cortex, posterior cingulate) associated with self-referential processing, making it a standard fMRI probe of the default mode network.

Inclusion test

An experiment is an instance of this task when its procedure matches, it manipulates at least one of the listed variables, and it records at least one of the listed measures.

Procedure

Participants judge trait adjectives under self-reference and comparison encoding conditions (other-reference, semantic, structural); a subsequent memory test assesses the self-reference effect on recall or recognition.

Manipulation

Encoding condition (self, other, semantic, structural); valence of adjectives (positive, negative, neutral); other-reference target (close other vs. distant other vs. celebrity); self-relevance (high vs. low); presentation modality.

Measurement

Self-reference effect (recall/recognition advantage for self-encoded items); endorsement rate by valence and condition; endorsement latency; recall bias (proportion positive vs. negative recalled); cortical midline activation (medial prefrontal cortex, posterior cingulate).

Variations

Named versions that change what the participant experiences or does. The identifier of a variation is hedvar_<task>__<variation>.

Description

Justification

Standard Trait Adjective Encoding

hedvar_self_referential_encoding__standard_trait_adjective_encoding

Self/other/semantic/structural encoding of trait adjectives followed by surprise recall. The Rogers et al. (1977) design. The foundational paradigm.

Canonical: judge whether adjective describes self; incidental encoding

Positive/Negative Valence Split

hedvar_self_referential_encoding__positive_negative_valence_split

Separate analysis by adjective valence. Depression studies focus on the positive endorsement deficit and negative recall bias.

Valence-matched sets tested separately; tests self-relevance by valence

Close vs. Distant Other-Reference

hedvar_self_referential_encoding__close_vs_distant_other_reference

Compare self-encoding with encoding relative to mother, best friend, celebrity, or stranger. Tests whether self-reference advantage is graded by social closeness.

Encoding with reference to close vs. distant others; tests reference specificity

Incidental vs. Intentional Encoding

hedvar_self_referential_encoding__incidental_vs_intentional_encoding

Standard version uses incidental encoding (surprise memory test). Intentional encoding versions test whether self-reference benefit persists under deliberate memorization.

Explicit memory instruction vs. incidental; changes encoding goal

Endorsement-Only (No Memory Test)

hedvar_self_referential_encoding__endorsement_only_no_memory_test

Clinical use: just the self-endorsement phase. Patterns of positive and negative endorsement index self-concept content in depression.

Task without memory test phase; tests self-referential processing in isolation

Source Memory for Self-Encoded Items

hedvar_self_referential_encoding__source_memory_for_self_encoded_items

Combines self-referential encoding with source memory judgments. Tests whether self-reference enhances contextual recollection or just item familiarity.

Retrieval includes source judgment for self vs. other items; adds source component
