Indeed, when interacting with the environment, humans typically direct their gaze to where relevant information for the task at hand can be found. While walking, humans shift their gaze by using both eye and head movements, and the relative contribution of the head is more pronounced when the navigated surface's complexity increases. However, most work has examined average behavior across the duration of the performed task (i.e. walking), often neglecting that natural behavior is continuous and so is the process of acquiring visual information for the task at hand. Here, we want to tackle this limitation by investigating the temporal dynamics of the head's engagement for gaze shifts while freely walking on different surfaces. We leveraged a naturalistic dataset encompassing gaze behavior during unconstrained walking across the most frequently occurring surfaces in everyday life (flat-walking, slopes, stairs). Our results confirm the previously observed increase in alignment of the head and gaze orientation as a function of the surface's complexity. Additionally, our results support a continuous contribution of the head to update task-relevant visual information reflected in the increased rate of change in the head's angular pitch displacement and the coupling between eye and head movements throughout the most demanding \"stairs\" condition. Taken together, our work showcases the temporal characteristics of the increased active engagement of the head in visual guidance of gait as an effect of everyday-occurring surface complexities.</p>","PeriodicalId":7141,"journal":{"name":"Acta Psychologica","volume":"260 ","pages":"105680"},"PeriodicalIF":2.7,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the impact of AI-powered beauty filters and recommendation systems on TikTok, Instagram, and Snapchat on body image and aesthetic preferences among young women in urban Pakistan. Guided by critical media theories of algorithmic power and postcolonial beauty norms, we utilize a mixed-methods approach that combines a structured survey (N = 300) with in-depth interviews (N = 30). The quantitative survey employed validated Likert scales to measure the frequency of filter use, body dissatisfaction, awareness of digital manipulation, and preference for Eurocentric facial features. Linear regressions and moderation analysis tested three hypotheses. Results confirmed a robust positive relationship between filter use and body dissatisfaction (β = 57, p < .001, R² = 0.42) as well as a very strong link between time spent on social media and preference for Eurocentric features (β = 0.46, p < .001, R² = 0.75). Awareness of digital distortion did not significantly weaken the filter-dissatisfaction association (interaction p = .38). Interview data revealed a deep internalization of algorithmic beauty norms, showing that many women relied on filters for social validation despite recognizing their artificiality, echoing broader patterns of algorithmic visibility bias. These findings indicate that AI-curated beauty ideals can exacerbate body anxiety and colorism pressures in a Global South context. We discuss implications for media literacy, platform governance, and culturally sensitive interventions to resist the algorithmic colonization of aesthetics.</p>","PeriodicalId":7141,"journal":{"name":"Acta Psychologica","volume":"260 ","pages":"105734"},"PeriodicalIF":2.7,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This practical dilemma highlights a critical theoretical gap: while policy endorsement is theorized to be crucial, extant literature often conflates it with general policy attitudes, obscuring its unique identity-based mechanism grounded in value congruence. To address this theory-practice divide, this study introduces and tests the concept of identity-congruence policy endorsement-a psychological state arising from perceived alignment between policy mandates and self-identity-that is, an individual's internalized system of values, beliefs, and group affiliations. Grounded in the theory of planned behavior and the ABC model of attitudes, we posit a cognitive mediation model wherein this endorsement triggers compliance intention primarily through cognitive appraisal rather than affective appeal. The aim is to provide an evidence-based psychological account for the compliance problem and offer actionable insights for optimizing policy design. A cross-sectional survey of 448 Chinese medical students-a high-cognition population-was analyzed via structural equation modeling. The results revealed that endorsement strongly predicted cognitive attitude (β = 0.901, P < 0.001) but weakly impacted affective attitude (β = 0.225, P < 0.001). Crucially, while cognitive attitude significantly drove compliance intention (β = 0.444, P < 0.001), affective attitude showed no effect. Furthermore, the link between endorsement and intention was fully mediated by cognitive attitude. This indicates that for high-cognition individuals, compliance is a deliberative process driven by cognitive appraisal rather than affective appeal. Consequently, policy optimization should prioritize enhancing cognitive legitimacy through evidence-based parameter design, simplifying compliance procedures, and employing nudge theory to leverage cognitive biases. This study advances digital governance literature by delineating the cognitive mechanism of policy compliance, with implications extending beyond the Chinese context.</p>","PeriodicalId":7141,"journal":{"name":"Acta Psychologica","volume":"260 ","pages":"105628"},"PeriodicalIF":2.7,"publicationDate":"2025-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145273457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drawing on componential theory of creativity, this research examines how effective AI-related communication (clarity, timeliness, accuracy) drives creative work behavior, defined as the generation of novel, useful ideas in the workplace, in the financial services and FinTech sector. We propose that AI interaction engagement, an employee's cognitive and emotional immersion in AI tools, mediates this relationship, and that an AI support environment and employee AI trust jointly strengthen the mediated pathway. Data were collected in a multi-wave design from 448 employee-supervisor pairs across four major Saudi cities and analyzed using SmartPLS.

Additionally, categorical spatial relation processing played a crucial role in pseudo-word reading. Notably, children with less developed categorical spatial processing abilities demonstrated reduced differences in reading speed between mirrored and normal letters, suggesting that the ability to process categorical spatial relationships is essential for distinguishing between mirrored and standard letter forms.
