Is the manuscript presented in an intelligible fashion and written in standard English??> Reviewer #1: Yes Reviewer #2: Yes Reviewer #3: Yes ********** Reviewer #1: The manuscript presents a qualitative exploration of age-related differences in lay conceptualizations and valence of curiosity, using open-ended responses from younger (18-26) and older (62-94) adults. The study innovatively bridges a gap in curiosity research by examining lay definitions against established multidimensional scales like the 5DC and InC, revealing ~50% "miscellaneous" responses that challenge theory-driven models. Age comparisons add novelty, showing older adults emphasize social aspects and positivity more than younger ones. Strengths: Robust hybrid content analysis with high inter-rater reliability (κ ≥ 0.83 across samples), Adequate powered sample (N=155 post-exclusions) via convenience pools, with clear exclusion criteria for data quality, Transparent reporting of chi-square tests and frequencies, supported by tables/figures (e.g., joyous exploration dominant in both groups) Weaknesses: Potential priming bias: 1. Quantitative curiosity scales administered before open-ended questions may influence responses, despite miscellaneous codes mitigating this. 2. Limited generalizability due to demographics—primarily female samples, older adults mostly White, convenience sampling from York University pools. 3. Exploratory design lacks quantitative depth; chi-squares are descriptive but not adjusted for multiple comparisons. Key findings include age differences (e.g., older adults higher on social curiosity, younger on deprivation/thrill-seeking) and valence shifts (older: more positive/sincerity; younger: moderation due to harms like privacy invasion). ~50% miscellaneous suggests lay views exceed current frameworks. Recommendation: Accept with minor revisions: Expand diversity in future work, clarify priming impacts, and provide supplementary code frequencies (e.g., S1/S2 Tables). Strong contribution to developmental psychology of curiosity. Reviewer #2: I had the opportunity to review the manuscript titled “Age differences in the conceptualization and experience of curiosity: A qualitative study”. The manuscript addresses the important topic of curiosity. However, it attempts to take an approach different from standard curiosity research that is typically quantitative by employing qualitative methods. While I appreciate the effort of the researchers, I think the study falls short of a rigorous and insightful qualitative study that would provide deep insights. The main data is essentially open ended responses to a survey that is mostly quantitative using 5DC and InC items. And a major flaw is that these items are presented first before the open ended responses, which leads to all sorts of problems as the authors acknowledge. And more importantly, I would expect qualitative research to provide deeper insights into participants' responses via more proving prompts or follow-up interviews, for example. Instead, the respondent data is mostly quite superficial from a paid survey where the researchers had to enforce a minimum response length. Questions such as why the respondents said what they said, why they did not say certain things, how their views on curiosity may have changed over time (which is one way to address the question of curiosity differing by age), etc. are all left unaddressed. The authors seemed to have collected quantitative data from 5DC and InC but chose not to report them here (or triangulate with the qualitative data) (perhaps, saving for another publication?). There have been other studies that have employed qualitative approaches on curiosity (including mixed methods) with much more methodological rigor that I would have expected this manuscript to at least match. They used more probing prompts, interviews, combined quantitative data, etc. to obtain, in my opinion, deeper insights. Below are some examples: Han, J., Way, N., Yoshikawa, H., & Clarke, C. (2025). Interpersonal curiosity and its association with social and emotional skills and well-being during adolescence. Journal of Adolescent Research, 40(3), 636-668. Birenbaum, M., Alhija, F. N. A., Shilton, H., Kimron, H., Shahor, N., & Rosanski, R. (2023). Curious minds: Evidence from interviews with renowned experts in five curiosity-dominant fields. Birenbaum, M., Alhija, F. N. A., Shilton, H., Kimron, H., Rosanski, R., & Shahor, N. (2019). A further look at the five-dimensional curiosity construct. Personality and Individual Differences, 149, 57-65. I also question some of the claims made about 5DC and InC not able to capture some participant responses such as individual differences and innovation. The point of 5DC is to measure individual differences, cluster, and build curiosity profiles of individuals. And innovation partly overlaps with novelty aspects of I-type curiosity by Litman. It’s unclear what the unit of analysis is for the code. It’s clear that some participant responses are long and cover different aspects. I assume those responses are being given multiple codes? But some examples given are very short with ellipses, so I assume they’ve been trimmed by the authors? Minor comments: I don’t see how refs 1 and 2 can be used to support the statement “seen a resurgence in research on human curiosity”. Consider a more recent reference in PLoS One that can replace current ref 15: https://doi.org/10.1371/journal.pone.0320600 Reviewer #3: This study involves a qualitative analysis of curiosity definitions (what it is) and valence (is it positive or negative) for a group of younger and older adults. Overall, I find the study informative and interesting to the broader field trying to understand how to best understand and conceptualize curiosity, especially across the adult lifespan. I only have minor comments and clarifications. 1. My first question is about the fact that participants' "initial responses" to the valence question were coded. It's not entirely clear what the "initial response" is - is that the first few words that address the issue of valence? Was there a clear cutoff for initial response vs. rationale? Additionally, were there any cases where the rationale was overall different from the initial response? (e.g., they said it was positive but discussed negative aspects throughout the response) 2. It's not clear how the categories were decided on for the post-hoc coding into motivated learning, critical process, etc. Was there any specific process for coming up with these categories? And could the responses also count in more than one of these categories? 3. Similarly, it's interesting that morbid curiosity is a somewhat well-known phenomenon and these ideas tended to come up (e.g., the person who said they always ask how people died because they are interested, even if it's considered rude!). Did the authors consider including a morbid curiosity category for responses? The discussion of the potential for this category to be accounted for in measures of curiosity could also be expanded. 4. Were the responses of similar length across age groups? It seems like this was conducted on the computer, and older adults may be less accustomed to computers (though this is less of a concern as time passes). Is it possible that one age group expanded on their ideas more than another? 5. Could you say more about how older adults were recruited? I do not know what the Glendon Research Participant Pool is - are these participants involved in the university setting? 6. I think some of the references are off - especially in the 9-15 range. ********** what does this mean?). If published, this will include your full peer review and any attached files.).

Is the manuscript presented in an intelligible fashion and written in standard English??> Reviewer #1: Yes Reviewer #2: Yes Reviewer #3: Yes ********** Reviewer #1: Dear Author(s) I have carefully reviewed the revised manuscript titled “Age differences in the conceptualization and experience of curiosity: A qualitative study” (PONE-D-25-66736R1). The authors have thoroughly addressed the concerns raised in the previous review round, and the manuscript has been substantially strengthened as a result. Major Strengths Clear Contribution to the Literature The manuscript provides a novel and meaningful contribution to the curiosity literature by examining age differences in lay conceptualizations of curiosity. While much prior work has relied on theory-driven quantitative scales (e.g., the 5DC and InC), this study offers an exploratory qualitative perspective across the lifespan. This fills a clear empirical gap. Methodological Transparency and Rigor The authors have: Clarified the hybrid deductive–inductive content analysis approach. Clearly defined the unit of analysis and coding procedures. Provided strong inter-rater reliability statistics. Included FDR-adjusted p-values for chi-square analyses. Expanded discussion of limitations (e.g., priming effects, sampling constraints). These revisions significantly improve methodological clarity and credibility. Thoughtful Engagement with Reviewer Concerns The authors have constructively responded to critiques regarding: Priming effects from quantitative scales. Depth versus breadth in qualitative methodology. Coding development and rationale classification. Data transparency (OSF upload). Reference updates and citation corrections. The discussion now appropriately frames the study as an exploratory, descriptive first step rather than a deep phenomenological investigation. Data Transparency and Ethics The data availability statement, OSF repository upload, ethics approval (York University Office of Research Ethics, certificate #2024-294), and funding disclosure (Natural Sciences and Engineering Research Council of Canada) are clearly reported and compliant with journal standards. Interpretation and Framing Importantly, the manuscript now more accurately positions its findings: As descriptive age-related differences in conceptualization rather than causal or developmental claims. As complementary to established frameworks (e.g., 5DC), rather than as a critique of them. As groundwork for future in-depth qualitative or mixed-method research. The acknowledgment of limitations (e.g., convenience sampling, limited diversity, potential priming, non-interview format) is appropriate and balanced. Minor Observations The manuscript appears ready for publication. Any remaining minor stylistic or formatting adjustments can be handled during copyediting.
