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.

The relationship between the use of cannabis and the decisionmaking 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 nonconsumers 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. Nonconsumers 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-

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.

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.

Título: Independencia entre operaciones aritméticas básicas: evidencia desde la neuropsicología cognitiva. Resumen: Los casos descritos en la literatura ponen de manifiesto que las operaciones aritméticas pueden funcionar independientemente, lo que permite inferir que los procesos cognitivos implicados en las distintas operaciones podrían ser distintos. El objetivo de este trabajo es determinar los distintos procesos implicados en la resolución de operaciones aritméticas: suma, resta y multiplicación. Método. Instrumento: Batería de evaluación del procesamiento numérico y el cálculo (Salguero y Alameda, 2007, 2011. Sujetos: pacientes con daño cerebral adquirido. . Resultados y conclusiones: El paciente MNL conserva la suma y la multiplicación pero presenta alterada la resta. Por el contrario, el paciente PP manifiesta alteraciones en la suma y multiplicación pero conserva intacta la resta. ISR presenta un déficit selectivo para la multiplicación estando intactas la suma y la resta. Por último, ACH, conserva la suma pero tiene alteradas la resta y la multiplicación. Esta doble disociación confirma los postulados del modelo anatómico funcional de Dehaene y Cohen (1995, 1997), que plantea la existencia de una doble vía para la resolución de operaciones aritméticas simples: la ruta lingüística, para datos numéricos aprendidos memorísticamente, que se utilizaría para sumar y multiplicar, y por otro lado, la elaboración semántica, para la resta. Palabras clave: Daño cerebral; cálculo; neuropsicología cognitiva; doble disociación; operaciones aritméticas. Abstract:The cases described in literature evidence that arithmetical operations can function independently, which allows to infer that the cognitive processes involved in the different operations might be different. Objective of that work is to determine the different processes involved in the resolution of arithmetical operations: addition, subtraction and multiplication. Method. Instrument: Assesment of Numeric Processing and Calculation Battery , 2011. Subjects. Patients of acquired cerebral injury. Results and conclusions. The patient MNL preserves the addition and the multiplication but he presents altered the subtraction. On the contrary, the patient PP shows alterations in addition and multiplication but he conserves the skills for the subtraction. ISR presents a selective deficit for multiplication with intact addition and substraction. Finally, ACH preserves the addition but presents deficit for substraction and multiplication. This double dissociation confirms the postulates of the anatomical functional model of Dehaene and Cohen (1995, 1997) that consider a double route for the resolution of arithmetical simple operations: linguistic route, for numerical information learned automatically (of memory) and would be used for the operations of addition and multiplication, on the other hand the semantic elaboration would be for substraction.
