Youth Dating Violence, Behavioral Sensitivity, and Emotional Intelligence: A Mediation Analysis.

Intimate partner violence is a multidimensional phenomenon encompassing psychological, physical, and sexual components. Violence in young couples is common in our society. This kind of violence is usually bidirectional, which adds to its complexity. This study aimed to explore how victimization (in three dimensions: non-abuse, technical mistreatment, and mistreatment) and perpetration (in two dimensions: non-perpetrator and perpetrator) are related to the BIS (Behavioral Inhibition System)/BAS (Behavioral Approach System), and it also evaluated if the dimensions of emotional intelligence (EI) (emotional attention, clarity, and regulation) mediate this relationship. Violence was evaluated in 272 young volunteer participants, as well as BIS/BAS behavioral sensitivity and perceived emotional intelligence. The correlations between these variables were analyzed, and a mediation analysis was also conducted. The results show that victimization (of the sexual and coercive type) was associated with less BAS activation, while victimization (of the sexual, humiliation, and detachment types) was associated with less BIS activity. All types of victimization were associated with less EI, specifically with less emotional clarity. Aggression (of the sexual, humiliation, detachment, and coercion types) was related to lower BAS and higher BIS sensitivity. Detachment aggression was associated with low emotional clarity. In conclusion, relationships between victimization and perpetration are evidenced in terms of BIS/BAS sensitivity and EI. Specifically, the dimension of EI emotional clarity acts as a mediator of BIS activation in victims of detachment.

Emotional Intelligence as a Mediator between Subjective Sleep Quality and Depression during the Confinement Due to COVID-19.

In March of 2020, as a consequence of the health crisis caused by the SARS-CoV-2 (COVID-19) virus, the State of Alarm and home confinement of the entire population was imposed in Spain. It is foreseeable that this exceptional situation will have psychological effects on citizens. In this work, the impact of confinement on perceived sleep quality and depression is evaluated through questionnaires, as well as the mediating role of Emotional Intelligence (EI) in this relationship. Our results show, firstly, higher prevalence of depressive symptoms in women and young people associated with poorer perceived sleep quality, and secondly, that Emotional Intelligence intervenes as a mediator in this relationship through three different pathways. Worse perceived quality of sleep causes a greater number of depressive symptoms. In addition, this direct relationship may be enhanced by the mediating role of Emotional Intelligence, which we can express in three different ways: low perceived sleep quality and high emotional attention lead to greater depression; low perceived sleep quality and low emotional clarity increase greater symptoms of depression; and low perceived sleep quality together with low clarity and low emotional repair increase levels of depression. Therefore, we can conclude that improving the skills involved in Emotional Intelligence might increase perceived sleep quality, and thus reduce depressive symptoms, which in turn may improve the quality of life.

Impulsivity, Emotional Intelligence, and Alcohol Consumption in Young People: A Mediation Analysis.

Alcohol consumption in young people is a public health problem. Due to the harmful consequences and the large population using alcoholic substances, it would be important to determine the biological, psychological, and social factors associated with alcohol use and abuse. The main object of this study is to explore which components of impulsivity, according to the main theoretical models, have predictive power regarding alcohol consumption in young people. A secondary objective is to determine if emotional intelligence has a mediating role between the components of impulsivity and alcohol consumption, and thus specifically contribute to the knowledge about the mediation processes between those variables that are involved in the initiation and maintenance of alcohol consumption. For this purpose, 384 participants were recruited (83.1% females, n = 319), with mean age of 20.46 years (SD = 1.90; range 18-25). All participants were alcohol consumers at the beginning of the study. Data collection was conducted via online survey; impulsivity was evaluated by several questionnaires (Sensation Seeking Scale Form V, Barratt Impulsivity Scales 11, and Sensitivity to Punishment and Sensitivity to Reward), and emotional intelligence was evaluated by the Trait Meta-Mood Scale. The results reveal that the dimension of disinhibition (a dimension of the sensation search scale) significantly has the highest predictive value on alcohol consumption. Moreover, our data show that the total effect and direct effect of disinhibition on frequency of alcohol consumption were both significant. The mediating role of emotional intelligence in this process was also significant. These findings show which variables should be considered to prevent alcohol consumption in young people.

Implicaciones cognitivas en la estimación psicofísica del sabor / Cognitive implications in the psychophysical estimation of taste

Introducción: en la percepción sensorial del gusto, los conceptos de umbral absoluto (UA), los métodos psicofísicos para estimarlo y la influencia que ejerce el conocimiento previo sobre su percepción y reconocimiento son de difícil aprendizaje por su escaso estado de conciencia. Objetivo: evaluar los umbrales de detección de los cuatros sabores básicos en una muestra de jóvenes sanos, en condiciones de restricción de alimentos/no-restricción, y analizar la influencia del conocimiento previo de la astringencia para su detección-identificación. Método: se puso en contacto directo con las sustancias químicas de los sabores y de astringencia a 114 participantes con media de 20,03 años (DT = 5.45), el 75,4% mujeres, mediante una degustación teórica-práctica. Se aplicó un diseño de tratamiento invertido con las condiciones experimentales sobre restricción de alimentos y conocimiento de astringencia. Resultados: todos identificaron sus UA para los cuatro sabores básicos. El grupo con restricción fue significativamente más sensible (Tb = -3,305; p = 0,001) al dulce (UA = 2 g/l) que el grupo sin restricción (UA = 5 g/l). La detección-identificación de la astringencia resultó significativamente mayor (t = -13,323; p = 0,000) con información previa del nombre (79,31%) que sin esta información (19,64%), confundiéndola, o describiéndola, como sabor amargo (80,36%). Conclusiones: el aprendizaje del sabor se favorece cuando se realiza la medición psicofísica de los sentidos químicos junto a la formación de determinados conceptos teóricos sobre la percepción gustativa y denominación de sabores, al facilitar su proceso cognitivo posterior detección-identificación. También debe atenderse al proceso de homeostasis interna previa de los participantes por la variabilidad en los resultados de sus UA según las condiciones de hambre/saciedad anteriores a su estimación psicofísica

Introduction: in sensory perception of taste, it is difficult to learn the concepts of absolute threshold (AT), the psychophysical methods to estimate it and the influence exerted by prior knowledge on their perception and recognition, because they have little awareness. Objective: to assess absolute thresholds of four basic flavors in a sample of healthy young people, in conditions of food restriction/without restriction, and to analyze the influence of prior knowledge of astringency in its detection-identification. Methods: one hundred and fourteen participants with an average of 20.03 years old (SD = 5.45), 75.4% of them women, were put in direct contact with chemical substances of basic flavors and astringency through a theoretical-practical tasting. An inverted treatment design was applied with experimental conditions on food restriction and knowledge of astringency. Results: all identified their AT for basic flavors. The group with restriction was significantly more sensitive (Tb = -3.305, p = 0.001) to sweet (AU = 2 g/l) than the group without restriction (AU = 5 g/l). The detection-identification of astringency was significantly higher (t = -13.323, p = 0.000) with previous information of the name (79.31%) than without this information (19.64%), confusing or describing it as bitter taste (80.36). Conclusion: taste learning is facilitated with the performance of psychophysical measurements of chemical senses, together with training of certain theoretical concepts about taste perception and flavor denomination, because it facilitates the cognitive process for detection-identification. In addition, the process for the previous internal homeostasis of participants must be considered as their AU results vary according to the hunger/satiety conditions prior to the psychophysical estimation

Cognitive Mechanisms in Decision-Making in Patients With Mild Alzheimer Disease.

BACKGROUND: Alzheimer's dementia is characterized by significant cortical and subcortical atrophy, causing diverse neuropsychological deficits. According to the somatic marker hypothesis, the areas responsible for generating the somatic markers that anticipate the consequences of a decision and thereby optimize the process would be affected in these patients. OBJECTIVE: The aim of this experiment is to study the decision-making processes in Alzheimer type dementia patients to determine potential deficits in these processes as a result of the disease, aside from the cognitive impairment that is typical of aging. In addition, we wish to determine the defining characteristics of decision-making in these patients, on the basis of the prospect valence-learning parameters. METHOD: We evaluated 30 patients with Alzheimer's disease and a control group of 30 healthy subjects. A short version of the Iowa Gambling Task was used. RESULTS: The results showed that patients made less advantageous choices than did controls. Group differences were quantitative and qualitative, as significant differences in cognitive mechanisms identified in the prospect valence-learning decisions were observed. These results are consistent with evidence from neuroimaging studies as well as with work carried out with amnesic patients. CONCLUSION: That problems in our patients' decision-making could be due to the characteristic memory deficits of this disease, which prevents them from establishing new stimulus-reward relationships and eliminating previously learned responses as a result of the parietal and temporal atrophy they present.

Mecanismos cognitivos en la toma de decisiones arriesgadas en consumidores de cannabis / Cognitive mechanisms in risky decisionmaking in cannabis users

Se exploraron las relaciones entre consumo de cannabis y los procesos de toma de decisiones. Se empleó una versión informática de la Iowa Gambling Task (programa Cartas) en sus versiones normal e inversa y se aplicó el modelo Prospect Valence Learning (PVL) que caracteriza el proceso de toma de decisiones en base a los parámetros: Recencia, Consistencia, Aversión a las pérdidas y Regla de utilidad. Participaron 73 consumidores de cannabis y 73 no consumidores como grupo control. En la versión normal el grupo control obtuvo mejores puntuaciones que los consumidores. Ambos grupos se mostraron consistentes y con aversión a las pérdidas. Los controles estuvieron más influenciados por la frecuencia de las ganancias-pérdidas, mientras que los consumidores por su magnitud. La influencia de las elecciones inmediatas fue mayor en consumidores que presentaron un olvido rápido mientras que en los controles fue gradual. En la versión inversa, la ejecución de la tarea fue mejor en los controles. Ambos grupos mostraron consistencia, aversión a las pérdidas, más influenciados por la magnitud de las pérdidas-ganancias y con baja influencia de las elecciones inmediatas. Los resultados mostraron las relaciones entre consumo de drogas y el proceso de toma de decisiones, en consonancia con los obtenidos en otros trabajos, donde consumidores presentan peores resultados que controles, además, los parámetros del PVL nos permitieron caracterizar adecuadamente la toma de decisiones. Esto confirma la relación entre el consumo de drogas y la toma de decisiones, bien por la vulnerabilidad previa al consumo, bien por la neurotoxicidad de la drogas

The relationship between the use of cannabis and the decision making processes was explored. A computerized version of the Iowa Gambling Task (Cards Software) in its normal and reverse version was used, and the Prospect Valence Learning (PVL) model, which characterize the process of decision-making based on the parameters: Recency, Consistency, Loss aversion and Utility shape, was applied. Seventy-three cannabis consumers and a control group with 73 non consumers participated in the study. In the normal mode, subjects in the control group scored higher than cannabis consumers. Both groups showed consistent responses and aversion to loss. Non consumers showed greater influence of the gain-loss frequency, while consumers were more influenced by the magnitude of the gain-loss. The influence of immediate choices was higher among consumers who showed a quick oblivion while in the control group this process was more gradual. In the reverse mode, task performance was better among control group participants. Both groups showed consistency, loss aversion, more influenced by the magnitude of the gain-loss, and low influence of immediate elections. The results show the relationship between drug use and the decision making processes, being consistent with the results obtained in other studies where consumers had worse results than control group. Moreover, the PVL parameters allow to adequately characterize decision-making. This confirms the relationship between drug use and decision-making by either the vulnerability prior to consumption or the neurotoxicity of drugs

Conocimiento numérico cuantitativo y léxico: evidencia de doble disociación / Quantitative numerical and lexical knowledge: Evidence of double dissociation

El objetivo de este trabajo es determinar las implicaciones de una lesión cerebral concreta en el sistema de procesamiento numérico y el cálculo. El método empleado es el estudio de caso único, mediante la aplicación de pruebas de evaluación neuropsicológica. Los datos evidencian una doble disociación entre conocimiento numérico cuantitativo y cualitativo o léxico. Por un lado, la paciente M.C. preserva el conocimiento numérico cuantitativo tal como muestran los resultados en tareas de comprensión numérica y cálculo, sin embargo, presenta graves alteraciones en conocimiento numérico cualitativo. Por otra parte, M.L. conserva el conocimiento numérico cualitativo o léxico pero tiene gravemente alteradas las habilidades que requieren de la manipulación interna de cantidades, es decir, del conocimiento numérico cuantitativo. Estos resultados tienen dos implicaciones importantes: Primero, el conocimiento numérico cuantitativo podría estar compuesto por elementos susceptibles de dañarse de manera independiente. Y segundo, el conocimiento numérico cuantitativo es funcionalmente independiente del cualitativo

The aim of this work was to explain the involvement of a specific brain injury in the numerical processing and calculation system. The method employed was <> analysis and the administration of various cognitive neuropsychology tests. The results of this study revealed a double dissociation between quantitative numerical knowledge and qualitative or lexical numerical knowledge. Patient M.C. preserved quantitative numerical knowledge, as indicated by the results obtained in the numerical comprehension and calculation tasks. However, she showed a drastic deficit in qualitative numerical knowledge. On the other hand, patient M.L. preserved qualitative numerical knowledge, but she had serious problems in all the abilities that require internal manipulation of magnitude; that is, quantitative numerical knowledge. These results have two important implications, as conclusions: firstly, quantitative numerical knowledge may be made up of different elements susceptible to damage independently. And secondly, quantitative and qualitative numerical knowledge were functionally independent
