Self-Referential Encoding Task (SRET)

The paradigm behind Wu et al. (2026), and the wiki’s first dedicated instrument for self-referential processing rather than an interoceptive channel. Introduced by Derry & Kuiper (1981) as a test of the negative self-schema in depression, it asks a deceptively simple question — which words do you accept as describing you? — and reads depressive vulnerability off the answer.

What happens on a trial

The participant sees a trait adjective, positive (e.g. capable) or negative (e.g. worthless), under one of three instruction conditions:

• Self — “Does this word describe you?” (evaluative self-reference)
• Other — “Does this word describe [another person]?” (evaluative other-reference — a matched control for evaluation without self)
• Case — a non-evaluative perceptual judgement about the word itself (e.g. upper- vs lowercase), the baseline for word processing with no evaluation at all

The behavioural product is the endorsement pattern: the proportion of positive and negative words accepted as self-descriptive. The ratio of negative to positive self-endorsement is the negative self-referential bias (NSB) — the depressed and relapse-prone tend to endorse more negative and fewer positive self-traits. An incidental recognition memory test afterward can index whether self-referentially encoded words are better remembered (the self-reference memory effect).

In the scanner

Run during fMRI, the self / other / case contrasts localize the neural substrate of evaluative self-processing. Wu et al. (2026) used Self>Case as their primary contrast (self-relevant evaluation vs non-evaluative perception), with the mood induction interleaved so that self-referential encoding is measured under mild dysphoria — the state in which cognitive reactivity is thought to operate. Their conjunction analysis split the self condition by valence into a self-criticism map (activation to endorsed negatives + deactivation to endorsed positives) and a self-affirmation map — the elaborative-vs-embodied dissociation that ties the task to the dual-mode framework.

The task’s key lesson on this wiki

Wu et al. (2026) is where the SRET earns its methodological point: the behavioural bias and the neural activity during the task predict different things. Behavioural NSB tracked concurrent residual symptoms but not relapse; the neural markers (prefrontal activation, somatosensory deactivation) predicted relapse. A self-report endorsement bias and the brain activity underneath it are not interchangeable readouts of “self-referential vulnerability” — the reportable tendency indexes present burden, the neural signature indexes future risk.

Why it is on an interoception wiki at all

The SRET measures no bodily signal and is not an interoceptive task. It is here because Farb’s depression programme reads self-processing through the sensory-vs-elaborative dual mode (narrative-and-experiential-self-reference): negative self-evaluation as prefrontal elaboration, positive/present self-relation as somatosensory embodiment. The task is the vehicle by which that dyad gets a self-referential, clinically prognostic form — but the interoceptive reading of its “sensory” pole is Farb’s generalization, as with every study in the relapse arc.
