In neuropsychological diagnosis, there are two approaches that can be characterized as psychometric neuropsychology and qualitative neuropsychology, depending on the emphasis each one places on how difficulties are assessed during task performance. Psychometric neuropsychology focuses on quantifying correct or incorrect responses, and in some cases, a small numerical scale is assigned to performance (0, 1, 2). In qualitative neuropsychology, the emphasis is on analyzing the nature of errors and identifying under what conditions of activity regulation task performance improves or worsens. Qualitative analysis should be understood as a flexible and systematic process that allows for the diagnosis of alterations in the organization of psychological activity and provides insight for its reorganization. The objective of this study is to describe the syndromic analysis process in a case of ischemic stroke whose severity made it impossible to use psychometric tests or standardized protocols. A single-case observational design was used. The results made it possible to identify the syndrome of sequential motor organization, according to the model of A.R. Luria. The systemic effect of the primary defect on the patient's verbal activity is presented. The study concludes that qualitative analysis of signs and symptoms leads to an accurate diagnosis, thus laying the groundwork for the reorganization of the impaired functional systems. Keywords: qualitative analysis; Cerebrovascular Disease (CVD); neuropsychological mechanisms.

It remains a challenge to systematically and quantitatively assess the pragmatic performance of severely aphasic patients and determine severity levels. To this end, the ICRA-R Battery was designed based on the concepts of the Minimal Communication Circuit and the pragmatic features of the ICRA Method (Abraham & Brenca, 2013, 2016). It consists of four instruments. The psychometric analysis of the validation and reliability of Instrument 1 (Record and Script) and the expert-level validity of the CCA and CCP Questionnaires, which assess caregivers' perceptions of the patient's current and premorbid communicative competence, are described. Severity levels were established, and the developmental profile was graphed. Validity was analyzed by experts (> 93.1%), factor analysis and principal components extraction, analysis of agreement between evaluators (Fleiss's Kappa > 85%; Cohen's Kappa > 95.0%, inter-observer analysis applying intraclass correlation = 0.900 (95% CI: 0.791-0.957) and repeated measures ANOVA from means and confidence intervals) and internal consistency (Cronbach's Alpha 0.966). Keywords: Aphasia, Pragmatic Aspect, Psychometric Analysis, Basic Speech Act; Minimal Communication Circuit.

This article analyzes how emotional perception and neurocommunicative variables such as engagement, empathy, communicative self-efficacy, and cognitive load influence university teachers' intention to use teaching strategies. The study is based on the need to understand how teachers' emotions condition methodological adoption. A quantitative, non-experimental, cross-sectional approach with a correlational-explanatory scope was used. The sample consisted of 86 university teachers, and data were collected using the psychometrically validated PE-ENDU questionnaire. The analysis included descriptive statistics, Pearson correlations, and multiple regression developed in Python. The results show positive relationships between intention to use and valence, activation, and emotional relevance, as well as engagement and empathy-emotional regulation. Cognitive load did not have any significant negative effects. The predictive model explained 65% of the variance in intention to use. It is concluded that emotional and neurocommunicative processes are determinants in the adoption of active strategies, highlighting the importance of emotional well-being and communicative self-efficacy for pedagogical innovation.

This study examines the factors influencing the diagnosis of Autism Spectrum Disorder (ASD) in a sample of 67 children from Veracruz, Mexico. The analysis focused on the age at which the first symptoms were detected, the key agents involved in the identification process, and the time elapsed until diagnostic confirmation. Findings revealed an average delay of 4.35 years between the initial suspicion and the formal diagnosis. Preschool teachers were the primary identifiers of early warning signs (29.49%), followed by parents and physicians (27.86% each). The most commonly reported symptoms were language impairments (29.14%), behavioral problems (17.72%), and lack of eye contact (16.18%). These results highlight the urgent need to implement training strategies for educators and to strengthen screening protocols within the healthcare system, in order to reduce the diagnostic gap and promote early intervention, thereby improving the prognosis and quality of life of children with ASD and their families. Keywords: Childhood autism; early diagnosis; early intervention; autism spectrum disorder.

The advancement of the cosmetics industry—marked by constant innovation and increasingly discerning consumers—underscores the importance of studying how sensory stimuli influence purchasing decisions. This study focuses on examining the impact of sensory marketing, applied both to products and retail environments, on product choice and store loyalty. To this end, a questionnaire was developed for cosmetic users, including questions about the perception of scent, touch, color, and other stimuli. The results show that smell is the most influential sense in purchase decisions, followed by touch; however, the importance of each stimulus varies by product category, highlighting the need for tailored strategies. The research demonstrates a direct relationship between sensory marketing and buying behavior: by engaging the senses, brands create meaningful experiences, increase perceived value, and differentiate themselves from competitors, thereby greatly enhancing their chances of becoming the consumer’s preferred choice and strengthening customer loyalty.

The cover of our new special issue is no aesthetic whim; it is a statement of principles. An artistically intervened naked human body stands as the most honest metaphor for our biology: the skin as the primary interface where instinct, culture, and desire collide. Behind the beauty of this living canvas operates a silent, overwhelmingly complex machinery. Our cerebral cortex constantly decodes a flood of external stimuli, endowing them with affective meaning to ultimately drive our behavior. Yet, as you navigate the research in this edition, science reveals a fascinating paradox: no matter how much we sophisticate our environment through technology, luxury, or sound design, the human brain—the most complex structure in the known universe—keeps seeking exactly the same thing as that first naked body at the dawn of humanity: to be seen, to be felt, and to connect deeply with another. I invite you to dive into the pages of the Panamerican Journal of Neuropsychology with the same curiosity as one who observes our cover. Discover the silent architecture behind our decisions and bonds.
