Emotion regulation is pivotal in human interactions and well‐being. Modulating one's emotional state is intricately linked with psychological, behavioral, and physiological responses. Extensive research has explored how individuals with varying attachment orientations manage emotions, predominantly through self‐report measures and behavioral assess...
El presente estudio investigó el efecto de juego serio en las entrevistas de selección laboral en estudiantes de Ingeniería de la Universidad Católica del Norte (UCN), Chile. La aplicación constó de tres niveles para abordar las diversas partes de una entrevista de selección laboral. Esto permitió entrenar a los usuarios con estrategias para afront...
Introduction
Understanding how adults experience and regulate their emotions is strongly linked to attachment orientations. Numerous studies indicate emotional regulation difficulties in both attachment avoidance and anxiety. Additionally, emotional Event-Related Potentials (ERPs), such as the Late Positive Potential (LPP), reveal the process of em...
Psychedelics have a complex history marked by traditional use among indigenous cultures, early scientific interest, and subsequent prohibition. Despite their classification as controlled substances, recent decades have witnessed a resurgence of research into their therapeutic potential for various mental health conditions. However, most studies hav...
Cuando Blake Lemoine, ingeniero de Google, declaró que LaMDA, el chatbot en el que había estado trabajando, poseía consciencia, fue posteriormente despedido de la empresa. Este comentario avivó un debate en curso entre expertos en tecnología, filósofos y personalidades públicas sobre la posibilidad de que la inteligencia artificial (IA) alcance alg...
Executive functions (EFs) are a set of cognitive processes that enable individuals to manage and coordinate their thoughts and actions toward achieving specific goals. EFs include planning, organizing, initiating, and monitoring actions, and have been found to improve with age due to the maturation of the brain, especially during childhood. Therefo...

Cognitive decline, particularly in dementia, presents complex challenges in early detection and diagnosis. While Item Response Theory (IRT) has been instrumental in identifying patterns of cognitive impairment through psychometric tests, its parametric models often require large sample sizes and strict assumptions. This creates a need for more adap...
Background
Emotion regulation, the process by which individuals manage and modify their emotional experiences, expressions, and responses to adaptively navigate and cope with various situations, plays a crucial role in daily life. Our study investigates the variations in emotion regulation strategies among individuals with different attachment styl...
Emotion Regulation (ER) refers to the processes by which individuals influence their own emotions. It is a crucial aspect of human behavior, affecting everything from interpersonal relationships to mental health. The relationship between ER and Attachment Theory (AT) is pivotal. AT suggests that early bonds with primary caregivers influence future...
Introduction
Emotion Regulation plays a crucial role in human’s daily lives. Extensive research has shown that people with different attachment orientations exhibit divergencies in how they perform emotion regulation strategies.
Methods
44 adults performed an experimental emotion regulation task in which they were instructed to attend, reappraise,...
The Experiences in Close Relationships (ECR) questionnaire is a widely used self-report measure to assess adult attachment, based on two dimensions: attachment anxiety and attachment avoidance. This instrument has been adapted in multiple contexts, including the Chilean, for which there is an abbreviated version (ECR-12), that is the object of anal...
Previous research has shown the benefits of early detection and treatment of dementia. This detection is usually performed manually by one or more clinicians based on reports and psychometric testing. Machine learning algorithms provide an alternative method of prediction that may contribute, with an automated process and insights, to the diagnosis...
Planning is defined as the ability to develop a sequenced plan of behavioral steps to achieve a goal and is part of a set of high-order cognitive functions called executive functions. This function is affected in various daily life situations and in a variety of neuropsychiatric disorders (e.g., depression, anxiety, attention deficit disorder, schi...
Dementia is a syndrome caused by a myriad and include primary neurologic, neuropsychiatric, and medical conditions. It has been projected that the prevalence of dementia will triple in the elderly population by the year 2050. Despite the benefits of early diagnosis, there is an effective under-detection of around 62% of people with mild cognitive i...
Fibromyalgia (FMS) is a chronic condition that encompasses widespread pain associated with cognitive impairment and significant emotional distress related to functional disability. This study aimed to obtain evidence of the role of pain in the effect of time since FMS diagnosis and cognitive performance using a novel online protocol of neuropsychol...
Animals respond to threatening situations by exhibiting a number of defensive behaviors, including avoidance, freezing, and risk assessment. An animal model with an ethological approach offers a deeper insight into the biological mechanisms underlying threat responses. This paper describes a methodology to measure defensive behaviors toward both in...
Fibromyalgia (FMS) is a chronic condition that encompasses widespread pain associated with cognitive impairment and significant emotional distress related to functional disability that affects mainly women. However, the mechanisms underlying the origin of the cognitive impairments and how the current COVID-19 pandemic impacts remain elusive. This s...
There is abundant evidence about the negative impact of discrimination on well-being, but less research on factors that can reduce this negative effect, mainly focused on North American samples and with incipient development on South-South migration. The objective of this research was to analyze the effect of ethnic identity on the relationship bet...
Cognitive planning, the ability to develop a sequenced plan to achieve a goal, plays a crucial role in human goal-directed behavior. However, the specific role of frontal structures in planning is unclear. We used a novel and ecological task, that allowed us to separate the planning period from the execution period. The spatio-temporal dynamics of...
Neural correlates of cognitive planning are not understood well at present. Behavioral paradigms targeting this function are a current challenge in cognitive neuroscience. We recorded EEG activity while subjects were performing a novel behavioral paradigm that evaluates cognitive planning function. Participants showed longer reaction times and decr...
To assess, among Chilean students, the reliability and validity of three scales that measure attention deficit hyperactivity disorder (ADHD): the ADHD Rating Scale-IV (ADHD-IV); the scale for evaluating attention deficit disorder with hyperactivity (EDAH); and Spain's version of the ADHD Rating Scale-IV (Spa-ADHD-IV).
A study of the instruments was...
Objective: To evaluate the prevalence of Attention Deficit/Hyperactivity Disorder (ADHD) in the city of Antofagasta. Patients and Methods: Teachers and parents of 640 children (290 boys and 350 girls) between 6 and 11 years, from public, subsidized and private schools were evaluated through the Attention Deficit Hyperactivity Disorder Rating Scale-...
