# Sources and Standards Accessed September 12, 2026. ## Cognitive accessibility - W3C Web Accessibility Initiative, [Cognitive Accessibility at W3C](https://www.w3.org/WAI/cognitive/). Establishes that cognitive and learning disabilities can affect memory, attention, problem-solving, and comprehension, and identifies personalization as an accessibility direction. - W3C Web Accessibility Initiative, [Make Each Step Clear](https://www.w3.org/WAI/WCAG2/supplemental/patterns/o1p04-clear-steps/). Explains how visible location and progress help people resume after distraction or loss of focus. - W3C Web Accessibility Initiative, [Design Forms to Prevent Mistakes](https://www.w3.org/WAI/WCAG2/supplemental/patterns/o4p04-supportive-forms/). Recommends minimizing required input, accepting flexible formats, and using reliable correction and personalization. - W3C Web Accessibility Initiative, [Provide Search](https://www.w3.org/WAI/WCAG2/supplemental/patterns/o2p06-search/). Recommends friendly search, autocomplete, grouped results, previous searches, and spelling support. W3C cognitive-accessibility patterns are supplemental guidance, not WCAG conformance requirements. PIXIE uses them as design references rather than claiming certification. ## Event - OpenAI Academy, [AI Skills Jam for Older Adults — Twin Cities, MN](https://academy.openai.com/public/events/ai-skills-jam-for-older-adults-twin-cities-mn-rnt55ha8bt), event scheduled for September 16, 2026 at the Heritage Center of Brooklyn Center; workshop 9:00 a.m.–12:00 p.m. CDT with optional practice and Q&A until 1:00 p.m. ## Provider channels - Apple, [Product Feedback](https://www.apple.com/feedback/). Public entry point for hardware and software feedback. - Apple Support, [How to contact Apple for help with accessibility features](https://support.apple.com/en-us/HT209585). Accessibility-support and product-feedback routing. - Google, [Send feedback about Android accessibility](https://support.google.com/accessibility/android/answer/6151851). Android accessibility feedback route. ## Privacy boundary for future health-related work - U.S. Department of Health and Human Services, [Resources for Mobile Health Apps Developers](https://www.hhs.gov/hipaa/for-professionals/special-topics/health-apps/index.html). Describes the federal mobile-health-app assessment tool and potential applicability of HIPAA, FTC, FDA, COPPA, and related rules. - U.S. Department of Health and Human Services, [Use of Online Tracking Technologies by HIPAA Covered Entities and Business Associates](https://www.hhs.gov/hipaa/for-professionals/privacy/guidance/hipaa-online-tracking/index.html). Explains when tracking data connected to healthcare may involve protected health information. ## PIXIE Care research boundary The following sources inform the distinction between documented affect-labeling research and the untested PIXIE Care design analogy. They do not validate PIXIE Care. - Lieberman, M. D., Eisenberger, N. I., Crockett, M. J., Tom, S. M., Pfeifer, J. H., & Way, B. M. (2007). *Putting feelings into words: affect labeling disrupts amygdala activity in response to affective stimuli*. Psychological Science, 18(5), 421–428. PubMed: https://pubmed.ncbi.nlm.nih.gov/17576282/ . The study examined direct verbal labeling of emotional stimuli and reported reduced amygdala/limbic response relative to comparison encoding conditions. It did not test narrative-mediated reflection. [DOCUMENTED] - Lieberman, M. D., Inagaki, T. K., Tabibnia, G., & Crockett, M. J. (2011). *Subjective responses to emotional stimuli during labeling, reappraisal, and distraction*. Emotion, 11(3), 468–480. PubMed: https://pubmed.ncbi.nlm.nih.gov/21534661/ . The paper reports four studies of self-reported emotional response to labeling and related conditions. The proposal's prompted narrative reflection should not be treated as equivalent to the studied paradigm. [DOCUMENTED] - Kircanski, K., Mortazavi, A., Castriotta, N., et al. (2012). *Feelings into words: contributions of language to exposure therapy*. Behaviour Research and Therapy. PubMed: https://pubmed.ncbi.nlm.nih.gov/22902568/ . This study examined affect labeling during live spider exposure therapy; the affect-labeling group showed reduced skin conductance at follow-up but did not differ from other groups in self-reported fear. Its clinical exposure context is not analogous to PIXIE Care and does not validate it. [DOCUMENTED / BACKGROUND ONLY] - Niles, A. N., et al. (2015). *Affect labeling enhances exposure effectiveness for public speaking anxiety*. PubMed: https://pubmed.ncbi.nlm.nih.gov/25795524/ . The study examined affect labeling during exposure for public-speaking anxiety and found greater reduction in physiological activation, with no effect on self-report. Its exposure-therapy context does not establish effects for PIXIE Care. [DOCUMENTED / BACKGROUND ONLY] - Burklund, L. J., Creswell, J. D., Irwin, M. R., & Lieberman, M. D. (2014). *The common and distinct neural bases of affect labeling and reappraisal in healthy adults*. PubMed: https://pubmed.ncbi.nlm.nih.gov/24715880/ . The sample was healthy older adults (N=39). The findings inform plausibility of the studied mechanism but do not establish applicability to people using PIXIE Care alongside care. [DOCUMENTED / POPULATION-LIMITED] - Kashdan, T. B., et al. (2015). Work on emotion differentiation is relevant to the general concept of making finer-grained distinctions among emotional states. It does not demonstrate that a five-position narrative spread improves emotion differentiation. Any relationship to PIXIE Care is a design hypothesis, not a validated effect. ### Design-analogy rule A research source may support a statement about what the study actually tested. It may not be used as evidence that PIXIE Care has the same effect unless the actual PIXIE interaction has been directly studied. In particular, narrative mediation, voluntary prompting, population differences, and absence of physiological outcome measurement remain material gaps. These sources do not validate PIXIE's hypothesis. They inform its accessibility, feedback, safety, and evidence-boundary approach.
