With age, they acquire an exact number system for precise numerical information representation. The relations between these two systems and their correlations with math abilities in children remain unclear. In this study, 8- to 10-year-old children (<em>N</em> = 119) completed two tasks to test the integration of symbolic and non-symbolic numerical information (i.e., “symbolic integration”) and how this integration relates to children’s formal math abilities. For the number comparison task, involving dot arrays and Arabic numerals, children indicated which of two sequentially presented stimuli was larger. These stimuli were either in the same format (dot–dot or numeral–numeral) or in a mixed format (dot–numeral or numeral–dot). For the number–letter discrimination task, participants identified numerals or letter pairs co-occurring with dot arrays that either matched or mismatched the numeral’s quantity. In the number comparison task, we found that children were significantly slower when comparing mixed-format stimuli versus same-format conditions, suggesting a lack of symbolic integration (i.e., “symbolic estrangement”). In contrast, in the number–letter discrimination task, children were significantly faster in tasks where the dot arrays and numerals matched, indicating symbolic integration. While we found correlations between number processing and math skills at the condition level for both tasks, neither of the derived measures of symbolic estrangement or symbolic integration correlated with children’s performance on a standardized math assessment. Thus, we conclude that numerical integration or estrangement is task dependent and that symbolic integration has limited impact on 8- to 10-year-old children’s math abilities.</div></div>","PeriodicalId":48391,"journal":{"name":"Journal of Experimental Child Psychology","volume":"256 ","pages":"Article 106263"},"PeriodicalIF":1.8,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843732","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The question remains, however, what the underlying cognitive processes and mechanisms are that drive this improvement. Some authors have suggested that this is due to an increased numerical precision (i.e., the sharpening hypothesis), whereas others have proposed that the more accurate performance is due to the improved ability to inhibit non-numerical features of the display such as object size and spacing of items (i.e., the filtering hypothesis). The current study examined the developmental trajectory of numerosity perception across three age groups (<em>M</em> = 5.65, <em>M</em> = 11.03, and <em>M</em> = 20.10 years). As expected, more accurate performance was observed with age. Regression and analyses of variance revealing the contribution of numerical and non-numerical predictors in performance show that the performance in all age groups was primarily driven by numerical information and that its contribution increased with age. In addition, a consistent bias toward non-numerical features was observed in all age groups. These results support the sharpening hypothesis for children from 5 years of age to early adulthood, suggesting that from this age onward children increasingly focus on numerical information as they get older.

To do so, 54 parent–child dyads with children aged 24 to 46 months were recruited and tested at two time points. Parents’ metamemory repertoire was estimated using a questionnaire requiring the generation of as many different strategies as possible to solve various memory scenarios. The frequency of parents’ metacognitive comments during a standardized discussion about a past event with their children was used as a measure of metacognitive talk. An associative recognition memory task was used to assess children’s memory performance. Our results revealed that the effect of parental education level on children’s memory was serially mediated by children’s exposure to metacognitive talk via the richness of parents’ strategic memory repertoire. Specifically, parents with higher educational attainment were likely to nominate more memory strategies than parents with a lower level of education.

Many researchers flag and exclude NSR trials prior to analysis, which could lead to systematic bias if NSR (a) varies by demographic characteristics or (b) predicts health outcomes. Thus, in this study we characterized NSR and examined its potential beyond error by comparing it against DD with a secondary data analysis of the Adolescent Brain Cognitive Development (ABCD) Study—a population-based study that tracked youths (<em>N</em> = 11,948) annually from 8 to 11 years of age over 4 years. We assessed DD and NSR using the Adjusting Delay Discounting Task when youths were approximately 9.48 years old (<em>SD</em> = 0.51). We also examined three maladaptive health outcomes annually: sleep disturbances, obesity, and externalizing psychopathology. Our analysis revealed variations in NSR across races, ethnicities, and body mass index categories, with no significant differences observed by sex or gender. Notably, NSR was a stronger predictor of obesity and externalizing psychopathology than DD and inversely predicted the growth trajectory of obesity. These findings suggest that removing NSR patterns could systematically bias analyses given that NSR may capture unexplored response variability.
