“…Studies conducted to date investigated communication in neurological populations and healthy individuals. In samples of healthy individuals, the effects of age and education on communicative skills have been investigated (Fonseca, Ferreira, Liedtke, Muller, Sarmento, & Parente, 2006). More specifically, the effect of education was more frequent and robust than the effect of age, with some interactions suggesting a minor role for education with increasing age.…”

The history of Brazilian neuropsychology is traced at different neuropsycholinguistic stages with a focus on the importance of sociocultural factors. We first focus on language disorders, the sequelae of injuries in the left hemisphere, and neuropsychology restricted to the medical field in Europe, the United States, and Brazil. In the middle of the last century, attention to the interdisciplinary importance of studies on the right hemisphere began. Studies consequently emerged on the individual variability of brain function with both biological and cultural origins. Based on this approach, Brazilian studies on aphasic children and illiterate aphasic persons were disseminated internationally. In the 1970s, cognitive neuropsychology began in England, highlighting dysfunctions in reading and writing processes. The characteristics of writing systems within each language became relevant for the manifestations of acquired dyslexia. Brazilian studies showed deficits in Portuguese and Japanese writing caused by brain lesions. During this scientific journey, scientific societies and postgraduate programs in Brazil were created to facilitate exchanges and communication among young researchers. By the end of the last century and in the early 2000s, the growth of the neuropsychology of aging raised awareness of the complexity of sociocultural factors, not only on language research but also according to the level of education, frequency of reading and writing habits, school type, and interactions among these factors and biological factors, especially between the level of education and age. From this historical standpoint, we outline future directions and perspectives in the field of Brazilian neuropsychology.

“…The cognitive, communicative and emotional consequences of right hemisphere lesions are collected referred to as Right Hemisphere (RH) Syndrome (see Fonseca et al 2006). Studies of RH syndrome have also uncovered communicative deficits and impairments in EF.…”

“…Impulsivity may be related to inhibitory control and perseveration, which implies that the RH is involved in inhibition of impulsive responses. Fonseca et al (2006) reported that patients with damage in RH tend to respond quickly and impulsively on behavioural tasks, resulting in poor performance. Taken together these findings suggest that further investigation of EF deficits and impulsivity following RH damage is warranted.…”

The aim of this study was to evaluate executive functioning (EF) and impulsiveness in three groups of people aged 30 to 79 years: post-frontal stroke (n = 13) and post-extra-frontal chronic stroke of the right hemisphere (n = 31) and control (n = 38). The years of education varied between the groups was as follows, frontal lesion group: M = 12 (SD = 6.11); extra-frontal lesion group: M = 9.06 (SD = 4.94); and control: M = 9.61 (SD = 4.24) years. The following instruments were used: Behavioural Assessment Dysexecutive Syndrome, Wisconsin Card Sorting Test (WSCT), Barratt Impulsivity Scale, Impulsivity Evaluation Scale, Delay Descounting Task and Go/No-Go Task. We found differences in EF between the extra-frontal lesion group and the control group with respect to cognitive flexibility (p = .018); number of WCST trials (p = .018); WCST perseverative errors (p = .014) and omission by impulsivity errors on the go/no-go task for 250 ms (p = .008) and 1750 ms trials (p = .006). The frontal lesion group made more errors of omission than the control group in the 1750 ms go/no-go trials (p = .006). These results suggest that extra-frontal lesions impair EF by influencing attentional impulsivity.

“…These damages can be grouped into motor, cognitive, communicative and behavioral/emotional deficits, besides swallowing disorders and urinary incontinence (2) . The right hemisphere (RH) is involved in several cognitive functions such as memory (3) , temporal and spatial orientation (4) , attention (5) and praxis (6) . RH has important role in language, specifically in functional language aspects (1) .…”
