    Are valence and arousal related to the development of amodal representations of words? A computational study
    (['Taylor and Francis Group', 'Routledge'], 2023-11-21) Jorge Botana, Guillermo de; Martínez Mingo, Alejandro; Iglesias, Diego; Olmos, Ricardo; Martínez Huertas, José Ángel
    In this study, we analyzed the relationship between the amodal (semantic) development of words and two popular emotional norms (emotional valence and arousal) in English and Spanish languages. To do so, we combined the strengths of semantics from vector space models (vector length, semantic diversity, and word maturity measures), and feature-based models of emotions. First, we generated a common vector space representing the meaning of words at different developmental stages (five and four developmental stages for English and Spanish, respectively) using the Word Maturity methodology to align different vector spaces. Second, we analyzed the amodal development of words through mixed-effects models with crossed random effects for words and variables using a continuous time metric. Third, the emotional norms were included as covariates in the statistical models. We evaluated more than 23,000 words, whose emotional norms were available for more than 10,000 words, in each language separately. Results showed a curve of amodal development with an increasing linear effect and a small quadratic deceleration. A relevant influence on the amodal development of words was found only for emotional valence (not for arousal), suggesting that positive words have an earlier amodal development and a less pronounced semantic change across early lifespan.

    A Failed Cross-Validation Study on the Relationship between LIWC Linguistic Indicators and Personality: Exemplifying the Lack of Generalizability of Exploratory Studies
    (MDPI, 2022-10-13) Moreno, José David; Olmos, Ricardo; Martínez Mingo, Alejandro; Jorge Botana, Guillermo de; Martínez Huertas, José Ángel::virtual::4379::600; Martínez Huertas, José Ángel; Martínez Huertas, José Ángel; Martínez Huertas, José Ángel
    (1) Background: Previous meta-analytic research found small to moderate relationships between the Big Five personality traits and different linguistic computational indicators. However, previous studies included multiple linguistic indicators to predict personality from an exploratory framework. The aim of this study was to conduct a cross-validation study analyzing the relationships between language indicators and personality traits to test the generalizability of previous results; (2) Methods: 643 Spanish undergraduate students were tasked to write a self-description in 500 words (which was evaluated with the LIWC) and to answer a standardized Big Five questionnaire. Two different analytical approaches using multiple linear regression were followed: first, using the complete data and, second, by conducting different cross-validation studies; (3) Results: The results showed medium effect sizes in the first analytical approach. On the contrary, it was found that language and personality relationships were not generalizable in the cross-validation studies; (4) Conclusions: We concluded that moderate effect sizes could be obtained when the language and personality relationships were analyzed in single samples, but it was not possible to generalize the model estimates to other samples. Thus, previous exploratory results found on this line of research appear to be incompatible with a nomothetic approach.

    Toward a Biological, Psychological and Familial Approach of Eating Disorders at Onset: Case-Control ANOBAS Study
    (Frontiers Media, 2021-09-09) Sepúlveda, Ana Rosa; Moreno Encinas, Alba; Anastasiadou, Dimitra; Nova, Esther; Marcos, Ascensión; Gómez Martínez, Sonia; Villa Asensi, José Ramón; Mollejo, Encarna; Graell Berna, Montserrat; Martínez Huertas, José Ángel
    Eating disorders (ED) are considered as heterogeneous disorders with a complex multifactor etiology that involves biological and environmental interaction. Objective: The aim was to identify specific ED bio-psychological-familial correlates at illness onset. Methods: A case-control (1:1) design was applied, which studied 50 adolescents diagnosed with ED at onset (12–17 years old) and their families, paired by age and parents’ socio-educational level with three control samples (40 with an affective disorder, 40 with asthma, and 50 with no pathology) and their respective families. Biological, psychological, and familial correlates were assessed using interviews, standardized questionnaires, and a blood test. Results: After performing conditional logistic regression models for each type of variable, those correlates that showed to be specific for ED were included in a global exploratory model (R2 = 0.44). The specific correlates identified associated to the onset of an ED were triiodothyronine (T3) as the main specific biological correlate; patients’ drive for thinness, perfectionism and anxiety as the main psychological correlates; and fathers’ emotional over-involvement and depression, and mothers’ anxiety as the main familial correlates. Conclusion: To our knowledge, this is the first study to use three specific control groups assessed through standardized interviews, and to collect a wide variety of data at the illness onset. This study design has allowed to explore which correlates, among those measured, were specific to EDs; finding that perfectionism and family emotional over-involvement, as well as the T3 hormone were relevant to discern ED cases at the illness onset from other adolescents with or without a concurrent pathology.

    Emotional distress among older adults during the COVID-19 outbreak: understanding the longitudinal psychological impact of the COVID-19 pandemic
    (Wiley, 2021-10-29) López, Javier; Pérez Rojo, Gema; Noriega, Cristina; Velasco, Cristina; Martínez Huertas, José Ángel::virtual::4357::600; Martínez Huertas, José Ángel; Martínez Huertas, José Ángel; Martínez Huertas, José Ángel
    Background Older adults have proven their ability to overcome adversities throughout their life. This study aims to assess the impact of the COVID-19 pandemic on older adultsʼ psychological distress (anxiety and depression) over time. Methods A community-dwelling Spaniard population (N = 192) completed a survey and reported on their sociodemographic characteristics, appraisal and personal resources. Older adults took part in a longitudinal online survey collected in April 2020 (during the lockdown restrictions) and at two subsequent time points 3 and 9 months after baseline (without lockdown restrictions and during the third wave of the pandemic respectively). Results Older adults did not evidence higher emotional distress than during the initial lockdown. Furthermore, depression remained stable and anxiety significantly decreased. Results also suggest that some sociodemographic characteristics, appraisals and personal resources are relevant. Older participants showed less anxiety than younger ones. Furthermore, being a male, resilience, and acceptance were related with the decrease of anxiety. Otherwise, fear of the COVID-19 outbreak and depression were related with the increase of anxiety. Conclusion Older adults may adapt to the adverse pandemic impact by using more adaptive resources that reduce their distress. Efforts to ameliorate older adults' anxiety by focusing on older adults' personal resources should be considered.

    FoCo: una aplicación Shiny para la evaluación formativa usando modelos de diagnóstico cognitivo
    (Colegio Oficial de la Psicología de Madrid, 2023-05-03) Sanz, Susana; Nájera, Pablo; Moreno, José David; Sorrel, Miguel A.; Schames Kreitchmann, Rodrigo; Martínez Huertas, José Ángel
    La combinación de evaluaciones formativas y sumativas podría mejorar la evaluación. El modelado de diagnóstico cognitivo (MDC) se ha propuesto para diagnosticar fortalezas y debilidades de estudiantes en la evaluación formativa. Sin embargo, ningún software permite implementarlo fácilmente. Así, se ha desarrollado FoCo (https://foco.shinyapps.io/FoCo/), permitiendo realizar análisis MDC y teoría clásica de tests. Se analizaron respuestas de 86 estudiantes de grado a un examen de métodos de investigación, diagnosticándose sus fortalezas y necesidades en cuanto a su dominio de los contenidos de la asignatura y las tres primeras competencias de la taxonomía de Bloom y se analizó la validez de los resultados. El análisis ha sido informativo, ya que para estudiantes con puntuaciones similares ha sido posible detectar diferentes fortalezas y debilidades. Además, se encontró que estos atributos predicen criterios relevantes. Se espera que FoCo facilite el uso de MDC en contextos educativos.

    The processes of stress and coping in informal caregivers of people diagnosed on the schizophrenia spectrum. A longitudinal study
    (Fundación VECA para el Avance de la Psicología Clínica Conductual, 2023) Mora Castañeda, Belvy; Márquez González, María; Fernández Liria, Alberto; Cabrera, Isabel; Olmos, Ricardo; O'connell, Daniel; Martínez Huertas, José Ángel
    El objetivo de este estudio longitudinal fue analizar el papel del estrés y las estrategias de afrontamiento en la explicación de la carga y la depresión de familiares cuidadores de personas con diagnóstico del espectro de la esquizofrenia. Fueron evaluados 30 pacientes este diagnóstico y sus cuidadores informales (n=30). Los participantes fueron evaluados en tres momentos temporales: línea base, a los 5 meses y a los 10 meses. Se encontró una disminución de los niveles de carga subjetiva con el paso del tiempo. Asimismo, la carga subjetiva y la depresión del cuidador mostraron una mayor relación con aquellas variables del paciente relacionadas con la sintomatología negativa. A nivel longitudinal, la evitación y la resignación mostraron una notable relación con la carga subjetiva y la depresión. Los posibles cambios en la evaluación de las demandas que el trastorno plantea y en las estrategias de afrontamiento empleadas por los cuidadores sugieren el desarrollo de un proceso de adaptación al trastorno por parte del cuidador.

    The Revised Memory and Behavior Problems Checklist for Nursing Homes: Validation among Different Spanish Territories
    (MDPI, 2022-02-08) Velasco, Cristina; López, Javier; Pérez Rojo, Gema; Noriega, Cristina; Martínez Huertas, José Ángel
    Memory and behavioral difficulties among older people living in nursing homes can cause burden and other consequences in professional caregivers. There is a lack of instruments that evaluate these behaviors and their influence in formal caregivers. The aim of this study is to develop and psychometrically test—the Revised Memory and Behavior Problems Checklist for Nursing Homes (RMBPC-NH). A cross-sectional study was carried out. The sample was made up of 312 formal caregivers working in nursing homes from different territories in Spain, 87.5% were women and 12.5% were men. The average age of participants was 39 years (SD = 12.2). The sample was recruited from January 2019 to March 2020. Participants completed a self-administered questionnaire, which included sociodemographic information, and assessed quality of technical equipment, level of training, experience of working with older people, job satisfaction, professional quality of life, burnout, and conception of negative stereotypes held towards aging. The four-factor structure of the RMBPC-NH showed a good fit, namely in relation to memory, functional, and emotional factors, and other problems. It has shown adequate psychometric properties, internal consistency, and validity (correlations with professional quality of life, job satisfaction, burnout, and negative stereotypes). The RMBPC-NH is a useful instrument to evaluate the frequency of older people’s memory and behavior problems and professional caregivers’ burden. The practical application in nursing homes is discussed.

    Adaptación española de la "Escala de Comunicación Diádica Sexual"
    (Fundación VECA para el Avance de la Psicología Clínica Conductual, 2019) Jastrzebska, Olga; Martínez Huertas, José Ángel
    La comunicación diádica sexual consiste en tratar temas sobre comportamientos sexuales con la pareja. Dada la importancia de los aspectos sexuales en la comunicación con la pareja, el objetivo de este trabajo es presentar la adaptación española de la “Escala de comunicación diádica sexual” (Dyadic Sexual Communication Scale, CDS; Catania, 1998), un instrumento que mide la percepción de la comunicación con la pareja sobre comportamientos sexuales. 891 participantes contestaron distintas escalas para analizar la fiabilidad y la validez de la adaptación española de la escala de CDS. La estructura unidimensional obtuvo un buen ajuste (CFI= 0,92; TLI= 0,90; RMSEA= 0,079) y una buena fiabilidad (= 0,87; = 0,87). En el trabajo se presentan distintas evidencias de validez de la adaptación, como la validez convergente con variables de satisfacción sexual y de ajuste diádico con la pareja. También se analizó la sensibilidad a variables personales como el sexo o la duración de la relación de pareja mostrando que, aunque no hay diferencias de medias, la relación entre la escala CDS y las variables medidas es sensible a estas variables personales. P ALABRAS CLAVE: escala Comunicación diádica sexual, propiedades psicométricas, sexualidad, salud sexual, adaptación española.

    Redundancy, Isomorphism and Propagative Mechanisms between Emotional and Amodal Representations of Words: A Computational Study
    (['Springer', 'Psychonomic Society'], 2020-08-20) Jorge Botana, Guillermo de; Olmos, Ricardo; Martínez Huertas, José Ángel; Luzón Encabo, José María
    Some proposals claim that language acts as a link to propagate emotional and other modal information. Thus, there is an eminently amodal path of emotional propagation in the mental lexicon. Following these proposals, we present a computational model that emulates a linking mechanism (mapping function) between emotional and amodal representations of words using vector space models, emotional feature-based models, and neural networks. We analyzed three central concepts within the embodiment debate (redundancy, isomorphism, and propagative mechanisms) comparing two alternative hypotheses: semantic neighborhood hypothesis vs. specific dimensionality hypothesis. Univariate and multivariate neural networks were trained for dimensional (N=11,357) and discrete emotions (N=2,266), and later we analyzed its predictions in a test set (N=4,167 and N=875, respectively). We showed how this computational model could propagate emotional responses to words without a direct emotional experience via amodal propagation, but no direct relations were found between emotional rates and amodal distances. Thereby, we found that there were clear redundancy and propagative mechanisms, but no isomorphism should be assumed. Results suggested that it was necessary to establish complex links to go beyond amodal distances of vector spaces. In this way, although the emotional rates of semantic neighborhoods could predict the emotional rates of target words, the mapping function of specific amodal features seemed to simulate emotional responses better. Thus, both hypotheses would not be mutually exclusive. We also showed that discrete emotions could have simpler relations between modal and amodal representations than dimensional emotions. All these results and their theoretical implications are discussed.
