Personality and Progression Speed of Neurocognitive Disorders in Elderly People
2020 – 2022
Coordinators: Profa. Carmen Flores-Mendoza and Doctoral student Karen Saviotti
Some longitudinal studies have indicated a relationship between personality traits and the development of Neurocognitive Disorders (ND). In Brazil there is no study regarding individual personality differences and its influences on ND and rate of progression of cognitive decline. Our project will investigate this topic in a sample of elderly people (healthy volunteers and patients ND) using retrospective assessment of personality traits at younger age given by closest relatives (e.g. wife/husband). Additionally, current psychological and medical assessments will be conducted in year 1 and year 3.
Relationship between Monoamine Oxidase - A Polymorphism and Externalizing Behaviors in Students from Belo Horizonte, Minas Gerais.
2020 – 2023
Coordinators: Profa. Carmen Flores-Mendoza and Doctoral student Juliana Lopes Santos Apolinario
This project intends to study hyperactivity and antisocial behavior (also known as externalizing behaviors) in school adolescents through measures of activity of the enzyme MAOA, personality traits (based on the Big Five Model), hyperactivity/antisocial behavior, exposition to child maltreatment, intelligence, and socioeconomic status. In phase 1, eight public primary schools located in the city of Belo Horizonte will be randomly selected. Students aged 14 and 15 years old will be assessed with psychological measures. In phase 2, the enzyme MAOA will be analyzed in students who obtain low and high score in hyperactivity/antisocial. The project is being submitted to the Ethic Committee for approval.
MAO-A activity and its relationship with aggression and personality in the Military Police
2020 – 2023
Coordinators: Profa. Carmen Flores-Mendoza and Doctoral student Graciane Lopes Jardim
It is recognized that gene-environment interaction explains most psychological phenomena instead the study of unique variables (gene or social environment). We are going to initiate the study of aggressiveness and impulsiveness (strong components of antisocial behavior) through measures of activity of the enzyme MAOA, personality traits (based on the Big Five Model), aggressiveness/impulsiveness, exposition to child maltreatment, intelligence, and socioeconomic status. Military personnel, whose data will be analyzed according to their degree of exposition to the violence (special military force vs. common military force), will compose the sample. The psychological assessments will be conducted in year 1 and year 3. The project is being submitted to the Ethic Committee for approval.
High Cognitive Performance Screening Protocol for Teacher Use
2020 – 2021
Coordinators: Profa. Carmen Flores-Mendoza and Master student Gabriela Pereira Anunciação
Children are gifted when their intellectual ability is significantly above the norm for their age. In Brazil there is not any instrument or protocol for teacher use for detecting potential gifted children. This project will elaborate an educational protocol for screening high performance of schoolchildren based on research in psychology differential. Currently it is known that school performance tests composed by problem solving items instead knowledge items have high association with intelligence tests. In phase 1, eight public primary schools will be randomly selected. Schoolchildren aged between 9 and 11 years old will be assessed through a school proof composed by problem solving items, and teachers will be invited to respond to the Scale for Rating the Behavioral Characteristics of Superior Students. In phase 2, children who obtain highest (n = 40) and lowest scores (n = 40) on the school proof, will be submitted to psychometric intelligence and processing speed measures in order to validate the screening protocol. The project is being submitted to the Ethic Committee for approval.
Longitudinal study of intelligence and personality in a sample of students.
Coordinator: Dr. Carmen Flores-Mendoza
Student team: Undergraduate and graduate students.
Longitudinal studies employ continuous or repeated measures to follow particular individuals over prolonged periods of time—often years or decades. The benefit of this type of research is that it allows researchers to look at changes over time. For this reason, our Lab conducted a psychological longitudinal study of a cohort of students enrolled at the Centro Pedagogico, a primary school located on the University campus. The study began in May 2002 with the assessment of 600 children attending 1st to 8th grade (7 to 15 years old). Intelligence and personality measures were used. The cohort was assessed in 2004, 2006, 2008 and 2010. In 2014-2017 a sample of 100 young adults, assessed in 2002, participated of new assessments. Partial results can read in:

NEO PI-R adaptation to the Brazilian context
Coordinator(a): Dra. Carmen Flores-Mendoza
Financial support: VETOR publishing.
The questionnaire NEO PI-R is the self-reporting instrument most used for personality assessment around the world. Created by the American researchers Paul Costa and Robert McCrae, NEO PI-R is based on the model called Big Five. In Brazil, the adaptation was based on responses from more than 1,000 adults residing in the states of Santa Catarina, São Paulo and Minas Gerais. The findings were summarized in the technical manual prepared by the Laboratory of Individual Differences Assessment and supported by the publisher VETOR. Additionally, the rules of the short version, called NEO FFI-R, based on 60 items, were produced under the guidance of Professor McCrae.
