Perceptual expertise is widely assumed to refine multisensory perception, yet the empirical literature appears inconsistent. Trained musicians show narrower audiovisual temporal integration windows and quicker segregation, whereas experienced wine tasters seem more influenced by a wine's color in their aroma and flavor judgments than novices are. We argue that the inconsistency arises from a conflation of two formally distinct quantities: the prior probability that concurrent signals arise from a common source, and the coupling between the values of signals that share one. We present a generative model in which both are free parameters, along with channel precision and a decision criterion, that contains causal-inference and coupling-prior models as special cases. The model shows that the correlation between the values of two signals across an environment reflects only the product of the two priors, so that a correlation-tracking learner acquires the coupling when the signals always share a source, whereas separating the two priors requires representing causal structure; that binary common-source reports confound the common-cause prior with the decision criterion; that the coupling trades off against the measurement noise of the influencing channel unless its precision is measured independently; and that the two priors leave distinct signatures in how cross-modal influence varies with disparity. When the source is fixed, as for the color and odor of a wine, tighter coupling alone produces the conjunction of greater displacement by color and better discrimination between wines reported for experienced tasters, which no change in odor precision can produce. Simulations of a test battery combining continuous estimates, common-source reports and discrimination thresholds show that the parameters can be recovered, that a within-subject dissociation can be detected with conventional sample sizes under illustrative effect sizes, and that recovery fails in certain cases. The account yields a rule classifying environments by their base rate of common causation and their coupling strength, and the same ambiguity attends claims about altered multisensory processing in autism and aging. We also show that the most cited demonstration of expert susceptibility to color contains no expertise manipulation, and suggest that apparent expert biases may reflectwind calibration to real-world statistics.
Poetry is persistently perceived as more difficult than narrative prose among ESL/EFL learners, yet whether this difficulty is intrinsic to the genre or structurally mediated remains undertheorised. This study examined whether Grade 8 ESL/EFL learners’ poetry difficulty may be associated with institutional–cognitive misalignment rather than inherent genre complexity. Employing a convergent mixed-methods case study design, eleven Grade 8 students from a private school in Kathmandu, Nepal, completed controlled genre comparison tasks using thematically identical poetic and prose texts, alongside a 50-item Universal Design Learning (UDL)-aligned cognitive engagement instrument mapped onto Cattell–Horn–Carroll (CHC) domains. Within this bounded classroom context, descriptive patterns revealed a performance asymmetry: 54.54% of participants demonstrated at least partial success in prose comprehension, whereas 72.72% of participants failed the poetry task entirely. Cognitive profiling indicated a within-subject pattern of relatively higher engagement in Crystallised Knowledge and relatively lower engagement in Fluid Reasoning and Long-Term Storage and Retrieval, a domain theoretically implicated in poetic interpretation. Because the profiling instrument was purpose-built and was not designed to support between-domain psychometric comparison, this pattern is reported as a relative within-sample profile rather than as evidence of differential cognitive strength. A further metacognitive misalignment was found, suggesting a possible “brevity-as-ease heuristic”, wherein learners conflated the poetry shorter length relative to its prose with reduced cognitive demand. These patterns are consistent with a possible role for differential rehearsal of cognitive processes within a prose-dominant, examination-oriented curriculum rather than from inherent textual opacity. The study advances a provisional institutional–cognitive alignment framework to guide future large-scale investigation across examination-driven ESL/EFL contexts.
شعر همواره در میان زبانآموزان انگلیسی به عنوان زبان دوم یا خارجی (ESL/EFL) دشوارتر از نثر روایی تلقی میشود، اما اینکه آیا این دشواری ذاتی این ژانر است یا به واسطه ساختارها میانجیگری میشود، همچنان کمتر نظریهپردازی شده است. این پژوهش بررسی کرد که آیا دشواری شعر برای زبانآموزان پایه هشتم ESL/EFL ممکن است ناشی از ناهماهنگی شناختی-نهادی باشد تا پیچیدگی ذاتی ژانر. با بهکارگیری طرح مطالعه موردی آمیخته همگرا، یازده دانشآموز پایه هشتم از یک مدرسه خصوصی در کاتماندو، نپال، وظایف مقایسهای کنترلشده ژانر را با استفاده از متون شعری و نثری با موضوع یکسان انجام دادند و همزمان یک ابزار سنجش درگیری شناختی ۵۰ مادهای منطبق با Universal Design Learning (UDL) که بر حوزههای Cattell–Horn–Carroll (CHC) نگاشت شده بود را تکمیل کردند. در این زمینه محدود کلاسی، الگوهای توصیفی عدم تقارن عملکرد را نشان داد: ۵۴.۵۴٪ از شرکتکنندگان حداقل موفقیت نسبی در درک نثر داشتند، در حالی که ۷۲.۷۲٪ از شرکتکنندگان در تکلیف شعر کاملاً ناکام ماندند. نمایهسازی شناختی نشان داد که الگوی درونفردی با درگیری نسبتاً بالاتر در دانش تبلور یافته (Crystallised Knowledge) و درگیری نسبتاً پایینتر در استدلال سیال (Fluid Reasoning) و ذخیرهسازی و بازیابی بلندمدت (Long-Term Storage and Retrieval) وجود دارد؛ حوزههایی که از لحاظ نظری در تفسیر شعر نقش دارند. از آنجا که ابزار نمایهسازی به طور اختصاصی ساخته شده و برای مقایسه روانسنجی بین حوزهای طراحی نشده بود، این الگو به عنوان نمایه نسبی درون نمونه گزارش میشود و نه به عنوان شواهدی از قوت شناختی متفاوت. همچنین ناهماهنگی فراشناختی دیگری مشاهده شد که به وجود یک «کشف میانبر اختصار به عنوان سهولت» (brevity-as-ease heuristic) اشاره دارد؛ جایی که زبانآموزان کوتاهی شعر نسبت به نثر را با کاهش تقاضای شناختی اشتباه گرفتهاند. این الگوها با نقش احتمالی تمرین متفاوت فرایندهای شناختی در یک برنامه درسی غالباً مبتنی بر نثر و آزمونمحور سازگار است تا با ابهام ذاتی متن. این پژوهش چارچوبی مقدماتی برای همترازی شناختی-نهادی ارائه میدهد تا راهنمای تحقیقات آتی در مقیاس وسیعتر در زمینههای ESL/EFL آزمونمحور باشد.
