Giftedness is a rare behavioral phenomenon, which probably explains few empirical studies conducted in Brazil on this subject. In 2009, the Coloured Progressive Matrices of Raven (CPM) was administered to 2196 students aged between 9 and 10 years of age, enrolled in 25 public schools located in Belo Horizonte. In 2011 the same measure was administered to 66 students enrolled in a private school, one of the best school located in Belo Horizonte city. The raw score obtained in the total sample was transformed to a metric scale of IQ. The results indicated 7% of students from public school with IQ ≥ 120 against 55% of students of private school. In 2021 a new study will replicate the same survey (this time including more private schools). Additionally, two studies (in 2012 and 2018) were conducted using EEG with children of high and medium cognitive performance. The main findings can be read in:

The investigation of cognitive sex differences has been a standard academic practice; however, the results, never well understood, use to involve large discussions in several social settings. According to the Brazilian Educational census 2016, women represent 57% of students enrolled in universities. However, more women are in Human Sciences (60.5%), Health (56.3%), and Linguistics and Arts (69.5%); while more men are in Engineering/Computer Sciences (75.8%) and Exact/Earth Sciences (70.4%). We analyzed the cognitive performance of adults, aged between 18 and 59 years, varying in education level and purchasing power. Although women are the majority in undergraduate and graduate courses, they become a minority in science. Only 30% become a scientist. We analyzed sex differences in several cognitive measures and scientific production (published papers). See study in:

Study of Latin American Intelligence - SLATINT


Coordinator: Dra. Carmen Flores-Mendoza

Financial Support: VETOR Publishing and National Council for Scientific and Technological Development-CNPq.


The SLATINT project intended to identify the cognitive condition of 4000 students enrolled in 66 schools of six Latin-America cities (Belo Horizonte, Rosario, Lima, Santiago, Bogotá and Federal District of Mexico). The SPM [Standard Progressives Matrices of Raven], Inductive Reasoning test, BIS Battery, short version of PISA/2003 and a socioeconomic questionnaire were administered to all samples. The main findings can be read in:

Study of the individual differences in psychopathy in a forensic population of Minas Gerais through PCL-R.


Coordinator: Dr. Carmen Flores-Mendoza

Student: Marco Antonio Alvarenga (2005 – Master degree)


In 2005 the Laboratory of the Individual Differences Assessment conducted an investigation on psychopathy using the Scale Hare PCL-R. 120 inmates held in four prisons of Minas Gerais participated in this study. The results obtained replicate those reported in international literature. The main findings can be read in:
