Abstract

In this paper, we present Health Buddy, a voice agent integrated into commercially available Voice User Interfaces (VUIs) to support informal self-regulated learning (SRL) of health-related topics through multiple learning strategies and examine the efficacy of Health Buddy on learning outcomes for younger and older adults. We conducted a mixed-factorial-design experiment with 26 younger and 25 older adults, assigned to three SRL strategies (within-subjects): monologue, dialogue-based scaffolding building, and conceptual diagramming. We found that while younger adults benefit more from scaffolding building and conceptual diagramming, both younger and older adults showed equivalent learning outcomes. Furthermore, interaction fluency (operationalized by the number of conversational breakdowns) was associated with learning outcomes regardless of age. While older adults did not experience less fluent conversations, interaction fluency affected their technology acceptance toward VUIs more than younger ones. Our study discusses age-related learning differences and has implications for designing VUI-based learning programs for older adults.

      The Literature Review compares younger and older adults’ attitudes toward computers and discusses older adults’ learning of technology, but it does not compare how the two age groups learn. The Methods describe participants who were all older adults. Searches for age-related differences in technology learning found no passage establishing the claimed difference. (LLM, conf=0.75)

      Section 2.2 says VUIs have the potential to lower older adults’ barriers to using digital technology compared with traditional interfaces, and Section 6.4 reports increased confidence associated with the ease of voice-based interaction.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Statistics recomputed

Every reported test result, recomputed from its test statistic and degrees of freedom. A result shows as not adding up only once an independent check has confirmed it.

  • ConsistentF(2, 48) = 0.94reported p = .4 · recomputed p = .398

    “F(2,48)=0.94,p = .40”

  • ConsistentF(2, 50) = 5.28reported p < .01 · recomputed p = .008

    “F(2,50)=5.28,p < .01”

  • Consistentt(49) = -0.7reported p = .49 · recomputed p = .487

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Fluency coefficient points opposite to the claimed learning effect

    Major

    Higher interaction-fluency scores mean fewer breakdowns, but the reported negative coefficient associates higher scores with lower recall. The stated conclusion says higher fluency is associated with recalling more information.

  • Age effect on technology acceptance has an incompatible t statistic

    Major

    In Model 10, the age coefficient divided by its reported standard error is −0.60, not −2.51. The reported significance of this age effect therefore is not supported by the displayed coefficient and standard error.

    Reported -2.51 · recomputed -0.6

  • The non-native English speaker is assigned to the wrong age group

    Minor

    The participant description identifies the sole non-native English speaker as a younger adult. The demographic appendix instead lists an older adult whose native language is Chinese.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.

Statistics and arithmetic are recomputed, not judged.
