Eye Tracking Characterization of Algebraic Fraction Simplifications
(MDPI AG, 2025-12-18)
;
;
<jats:p>Several major studies require that students understand and master the concepts and procedures of mathematics. More specifically, an area of mathematics such as algebra requires students to be able to simplify, operate with, or solve fractions. Many students entering university show numerous shortcomings and errors, especially when simplifying algebraic fractions. This is why we conducted a study using eye-tracking techniques to better understand how students process these types of exercises in attentional terms, comparing students who can handle them successfully against those who show errors in their procedures. For this purpose, we evaluated the eye movements of 64 students from different university majors to characterize the attentional–visual strategies they use to simplify four different algebraic fraction exercises. We found that each type of simplification exercise needs a specific strategy where some parts of the rational algebraic expressions are cognitively relevant. Students with correct answers tend to allocate attention to these elements. Students with incorrect answers tend to find similar expressions with the intention to cancel them out, without applying any metacognitive thinking. The rational algebraic expression needs to be taught in a more conceptual manner than procedural.</jats:p>

<jats:p> Many of us “see red,” “feel blue,” or “turn green with envy.” Are such color-emotion associations fundamental to our shared cognitive architecture, or are they cultural creations learned through our languages and traditions? To answer these questions, we tested emotional associations of colors in 4,598 participants from 30 nations speaking 22 native languages. Participants associated 20 emotion concepts with 12 color terms. Pattern-similarity analyses revealed universal color-emotion associations (average similarity coefficient r = .88). However, local differences were also apparent. A machine-learning algorithm revealed that nation predicted color-emotion associations above and beyond those observed universally. Similarity was greater when nations were linguistically or geographically close. This study highlights robust universal color-emotion associations, further modulated by linguistic and geographic factors. These results pose further theoretical and empirical questions about the affective properties of color and may inform practice in applied domains, such as well-being and design. </jats:p>

<jats:p>Los consumidores suelen asociar sus preferencias con sabores específicos según la procedencia de los alimentos y bebidas; sin embargo, no siempre se consideran estas diferencias cuando se exportan dichos alimentos. Esta investigación presenta los resultados de un estudio diseñado para evaluar diferencias interculturales en la percepción de los consumidores mexicanos y colombianos de características organolépticas (gusto general, frescura, intensidad de color, intensidad de aroma, acidez) entre el arándano cultivar biloxi cultivado en México y Colombia. Se diseñó un estudio experimental basado en un cuestionario en el que 397 consumidores de ambos países (192 en México, 205 en Colombia) evaluaron distintos atributos sensoriales de dos muestras: un arándano mexicano y uno colombiano, ambos de la variedad biloxi. Adicionalmente, se realizó un análisis de microexpresiones faciales para complementar los resultados del experimento con indicadores de valencia emocional. Se demostró que ciertas correspondencias entre las propiedades organolépticas son consistentes en ambas culturas. Específicamente, en ambas nacionalidades, se evidencia un efecto significativo en los atributos acidez, amargura y dulzura. El arándano colombiano fue percibido más dulce, mientras que el arándano mexicano fue evaluado como más amargo y ácido. Cuando el arándano evaluado fue clasificado como más ácido, la calificación de gusto general fue más baja. Estos resultados son relevantes para los productores, comercializadores y exportadores de arándanos, sabiendo que aquellas variedades más dulces serán las que tendrán mayor aceptación por parte de los consumidores colombianos y mexicanos.</jats:p>

<jats:p>User experience (UX) is key in the immediate and future relationship between the client and business. Achieving a satisfying UX can only be achieved by understanding the wishes and user needs. The following study is carried out as an improvement tool for a Mexican coffee company. The objective is to achieve greater efficiency, attraction, and engagement on the part of the user. The main question is whether the new dynamic website design can directly increase the valence of user emotions compared to the static website design. To answer this question, 39 participants were exposed to the two different web page designs and elicited the following emotions using eye tracking and facial expression analysis (FEA) techniques: joy, anger, surprise, fear, contempt, disgust, sadness, neutral, positive, and negative. Through a Wilcoxon signed-rank test, the results showed a significant increase for the new dynamic design in the following emotions; joy, anger, surprise, disgust, fear and neutral. Thus, five of the seven basic emotions had a significant change that could lead to greater attraction and commitment on the part of the user and also influence, either consciously or unconsciously, their decision when interacting with the company.</jats:p>

Excessive use of short-form video platforms such as TikTok has raised growing concerns about digital addiction and its impact on young users’ emotional well-being. This study examines the relationship between continuous TikTok exposure and emotional engagement in young adults aged 20–23 through a multimodal experimental design. The purpose of this research is to determine whether emotional engagement increases, remains stable, or declines during prolonged exposure and to assess the degree of correspondence between facially inferred engagement and physiological arousal. To achieve this, multimodal biometric data were collected using the iMotions platform, integrating galvanic skin response (GSR) sensors and facial expression analysis via Affectiva’s AFFDEX SDK 5.1. Engagement levels were binarized using a logistic transformation, and a binomial test was conducted. GSR analysis, merged with a 50 ms tolerance, revealed no significant differences in skin conductance between engaged and non-engaged states. Findings indicate that although TikTok elicits strong initial emotional engagement, engagement levels significantly decline over time, suggesting habituation and emotional fatigue. The results refine our understanding of how algorithm-driven, short-form content affects users’ affective responses and highlight the limitations of facial metrics as sole indicators of physiological arousal. Implications for theory include advancing multimodal models of emotional engagement that account for divergences between expressivity and autonomic activation. Implications for practice emphasize the need for ethical platform design and improved digital well-being interventions. The originality and value of this study lie in its controlled experimental approach that synchronizes facial and physiological signals, offering objective evidence of the temporal decay of emotional engagement during continuous TikTok use and underscoring the complexity of measuring affect in highly stimulating digital environments.

<jats:title>Abstract</jats:title><jats:p>As people age, they tend to spend more time indoors, and the colours in their surroundings may significantly impact their mood and overall well‐being. However, there is a lack of empirical evidence to provide informed guidance on colour choices, irrespective of age group. To work towards informed choices, we investigated whether the associations between colours and emotions observed in younger individuals also apply to older adults. We recruited 7393 participants, aged between 16 and 88 years and coming from 31 countries. Each participant associated 12 colour terms with 20 emotion concepts and rated the intensity of each associated emotion. Different age groups exhibited highly similar patterns of colour–emotion associations (average similarity coefficient of .97), with subtle yet meaningful age‐related differences. Adolescents associated the greatest number but the least positively biased emotions with colours. Older participants associated a smaller number but more intense and more positive emotions with all colour terms, displaying a positivity effect. Age also predicted arousal and power biases, varying by colour. Findings suggest parallels in colour–emotion associations between younger and older adults, with subtle but significant age‐related variations. Future studies should next assess whether colour–emotion associations reflect what people actually feel when exposed to colour.</jats:p>
