Do poor readers retrieve words from memory in the same way?
People with weak vocabularies were less accurate at linking a verb back to its subject, but they retrieved the subject just as fast and by the same direct-access route as stronger readers.

Poor readers' retrieval mechanism: efficient access is not dependent on reading skill
Study at a glance
- Design
- Human experiment — Within-subject auditory multiple-response speed-accuracy tradeoff (SAT) task varying how much material separated a subject noun from its verb; Experiment 2 added vocabulary score as a continuous individual-difference predictor.
- N
- N=22 · 22 community participants aged 16-24 in Experiment 2 (the key test); the Methods section of Experiment 1 (university students) is missing from the available text, so its sample size is not stated here.
- Population
- Experiment 1: university students; Experiment 2: non-college-bound young people from the New Haven community with a wide range of vocabulary/reading skill
- Outcome
- Accuracy (d′ and asymptote) and retrieval speed (rate and intercept of SAT functions) for grammaticality judgements of subject-verb dependencies

What they did
Participants listened to sentences in which a verb was separated from its subject by nothing, by one relative clause, or by two, and judged whether the sentence was acceptable at many response tones, which traces how accuracy grows over processing time. Experiment 1 replicated an earlier reading study with university students using spoken sentences. Experiment 2 tested 22 young adults from the local community across two 3-hour sessions and related their performance to receptive vocabulary (a Peabody vocabulary test) as the index of reading ability.
What they found
In both experiments, accuracy fell as more material intervened; in Experiment 2 d′ dropped from 2.41 with no intervening clause to 1.32 with one and 0.73 with two. But retrieval speed was the same for the one- and two-clause sentences and only faster when no retrieval was needed, the signature of direct access rather than a backward search. Higher vocabulary predicted better accuracy overall, but it did not interact with distance and had no effect on any speed parameter.
The limits
What it doesn't show
Sentences were heard rather than read, so the study shows poor readers can use direct-access retrieval in listening, not that they do so while reading. The sample was small, which the authors acknowledge limits confidence about the absence of speed differences, and 'reading ability' was measured only by a vocabulary test. The available text also omits the introduction and Experiment 1 methods (including its sample size and example materials), and the abstract's mention of slower retrieval in poor readers does not match the reported null speed effects.
Key terms
- Speed-accuracy tradeoff (SAT) procedure
- A method that forces responses at many time points after a stimulus, so researchers can separate how fast information becomes available from how accurate it eventually is.
- Direct-access retrieval
- Content-addressable memory retrieval in which cues point straight to the target, so retrieval speed does not depend on how far back the target is.
- Search-based retrieval
- Retrieval that scans memory item by item, predicting slower retrieval the more material lies between cue and target.
- Asymptote
- The maximum accuracy reached with unlimited processing time, taken as an index of the quality or strength of the memory representation.
- Focal attention
- The very small active portion of memory holding the most recently processed item, which can be used without retrieval.

Common questions
If poor readers were less accurate, how can the authors say their retrieval works fine?
Accuracy and speed are separate measures in the SAT method. Lower accuracy points to weaker word representations, but the unchanged speed across distances shows the retrieval mechanism itself is the same direct-access kind used by skilled readers.
Why use spoken sentences to study reading?
Listening removes problems with decoding print, so any group difference can't be blamed on slow word recognition from spelling; it tests the memory mechanism itself.
Does this mean working-memory capacity doesn't matter for comprehension?
The authors argue that for linking a verb to its subject, only the most recent item needs to be held actively, so capacity differences are not the source of poor comprehension here; they point to representation quality instead.
