These modalities are typically assumed to reside within the body, such as in the sensorimotor system. A recent proposal argues that physical invariants, such as momentum or gravity, can also be substrates in which concepts can be grounded, expanding the assumed limits of grounding beyond the body. We here experimentally assessed this proposal by exploiting the representational momentum effect and the abstract concept of success. If success is grounded in the physical invariant momentum, the representational momentum effect should be larger for successful targets. We tested this hypothesis across four experiments (three pre-registered). In a surprising finding, we find hints that large trial numbers may hinder being able to find a representational momentum effect, which should be further investigated in future research. Regarding the central hypothesis, although only one experiment found statistically significant support, the effect tended toward the same direction in the three others as well. In order to draw robust conclusions about the results, we performed a mini meta, which aggregates the effects and inference statistics across the N = 271 participants. Across the four experiments, this effect was statistically significant, suggesting evidence in favor of the central hypothesis. These results should be interpreted with caution as there was inconsistency across experiments, suggesting the magnitude of the effect is small, and when asked who they believe moved faster, participants did not reliably indicate the successful target.</p>","PeriodicalId":48184,"journal":{"name":"Psychological Research-Psychologische Forschung","volume":"89 1","pages":"51"},"PeriodicalIF":2.2,"publicationDate":"2025-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11754331/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143025194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The latter comprises understanding the semantic meaning of numbers (i.e., their magnitudes) and potentially executing the appropriate mathematical operation. However, it is not yet clear whether number processing occurs after text processing or both take place simultaneously. We hypothesize that number processing occurs early and simultaneously with other problem-solving processes such as text processing. To test this hypothesis, we created non-solvable word problems that do not require any number processing and we manipulated the calculation difficulty using carry/borrow vs. non-carry/non-borrow within addition and subtraction problems. According to a strictly sequential model, this manipulation should not matter, because when problems are non-solvable, no calculation is required. In contrast, according to an interactive model, attention to numbers would be higher when word problems require a carry/borrow compared to a non-carry/non-borrow operation. Eye-tracking was used to measure attention to numbers and text in 63 adults, operationalized by static (duration and count of fixations and regressions) and dynamic measures (count of transitions). An interaction between difficulty and operation was found for all static and dynamic eye-tracking variables as well as for response times and error rates. The observed number processing in non-solvable word problems, which indicates that it occurs simultaneously with text processing, is inconsistent with strictly sequential models.</p>","PeriodicalId":48184,"journal":{"name":"Psychological Research-Psychologische Forschung","volume":"89 1","pages":"50"},"PeriodicalIF":2.2,"publicationDate":"2025-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11753309/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014220","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The close connection between confidence in perceptual judgments and planning of actions has been documented in studies investigating visual perception. Here, we extend this investigation to auditory perception by focusing on spatial hearing, in which the interpretation of auditory cues can often present uncertainties. We asked if confidence in perceived sound position changes when we interact with the sound source by planning a sound-directed motor action (reaching) vs. a verbal response (naming). We tested 30 participants in a sound localization task in which they were both asked to localize sound sources by reaching them or by naming the labels above them in a within-participants experimental design. Participants performed the task with binaural hearing and with one ear plugged to increase errors and reduce confidence. Results showed that sound localization performance did not differ between reaching and naming, and yet participants felt more confident and required less time to complete the trial when reaching to the sources compared to naming them, regardless of the listening condition. Moreover, we found that during monaural listening the coherence between performance and confidence was reduced in each trial, irrespective of response type, suggesting increased difficulties in metacognitive monitoring. These findings suggest that, even in the case of spatial hearing, motor action planning plays a role in the formulation of confidence judgments, alongside sensory inputs and decision-making processes and stress the importance of including metacognitive measurements into spatial hearing research.</p>","PeriodicalId":48184,"journal":{"name":"Psychological Research-Psychologische Forschung","volume":"89 1","pages":"48"},"PeriodicalIF":2.2,"publicationDate":"2025-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11743395/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143014215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To this end, we conducted two behavioral experiments wherein cognitive control was triggered by the confound-minimized Stroop task and the NFC questionnaire was administered. Two different forms of extrinsic motivation were manipulated at the block level. In Experiment 1, extrinsic motivation was triggered by evaluative feedback. In Experiment 2, extrinsic motivation was triggered by reward incentives, while evaluative feedback was selectively coupled with low (congruent)- or high (incongruent)- control demands trials. The results indicated that two forms of extrinsic motivation (evaluative feedback vs. reward incentives) presented distinctive effects on effortful cognitive control; while their benefits on overall performance were further influenced by NFC. Interestingly, when incongruent rather than congruent trials were selectively coupled with reward incentives, not only conflict processing, but also overall performance for low-NFC participants only, benefited from this scenario.

It is commonly assumed that an event file (or at least the SR binding) would end with the execution of the response or its action effect. This, however, has never been directly tested. Here, we tested whether the SR binding can be formed between another temporally close stimulus that people didn't respond to by implementing a sequence of two stimuli where participants needed to respond only to the first or second stimulus. Our results indicate that a binding between the response and this temporally close stimulus can occur, but only when it's placed after, and not before, the response execution. This finding suggests that the event file might operate a temporal binding window that is not decisively terminated by the response execution. Further, this insight into the temporal dynamics of the event file highlights the temporal flexibility of the SR binding and, thus, the need for careful consideration of its sub-structures and durability.</p>","PeriodicalId":48184,"journal":{"name":"Psychological Research-Psychologische Forschung","volume":"89 1","pages":"44"},"PeriodicalIF":2.2,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142956671","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
