5Ps Distractor Typology

A taxonomy of distractor kinds for EFL multiple-choice reading comprehension tests, proposed by Sun, Yang and Liu in Higher Education Studies (2026). The typology identifies five distinct distractor types — plausible, peripheral, polyconceptual, prejudicial, and pragmatic — each targeting a different conceptual or linguistic hurdle the test wants to discriminate against.

The 5Ps was developed from a triangulation of three sources: theoretical literature on multiple-choice design, analysis of attested test patterns in EFL exams, and expert practitioner judgement. It is intended as a working vocabulary for item authors rather than a competitor to broader item-writing taxonomies like Haladyna, Downing and Rodriguez (2002).

The five types

• Plausible. The default, classical distractor. Surface-coherent with the passage, reasoning-misaligned with the key, falsifiable on full comprehension. Targets candidates whose understanding is partial but whose decoding is intact.
• Peripheral. A distractor drawn from material adjacent to but not central to the target span. Targets candidates who recognise the passage's vocabulary but mis-locate the relevant referent — a common error mode in scanning-heavy items.
• Polyconceptual. Combines two or more concepts the candidate has separately grasped. Targets the candidate who knows the parts but cannot integrate them. Especially diagnostic at higher proficiency where local comprehension is solid but global integration is the discriminator.
• Prejudicial. Aligns with a common prior belief or stereotype the candidate brings. Forces them to override schema with passage evidence. Targets the candidate who reads to confirm rather than to update.
• Pragmatic. Drawn from inferences a candidate would naturally make about author intent, register, or purpose, but which the passage does not support. Targets pragmatic over-reading.

Use in item design

The typology is most useful as a balance check. An item set with five plausible distractors per item is uniform; an item set that distributes across the 5Ps tests different hurdles and produces a richer discrimination profile. For diagnostic feedback, knowing which type of distractor a candidate selects can localise the comprehension breakdown more precisely than a binary right-wrong score.

For AI-assisted distractor generation the 5Ps offer a structured prompt schema. Generating one distractor of each type per item is a stronger instruction than "generate three plausible wrong answers" and produces more varied and pedagogically useful distractor banks.
