-The present article provides normative measures for 400 pictured objects (Cycowicz et al., 1997) viewed by Portuguese speaking Brazilian University students and 5-7 year-old children. Name agreement, familiarity and visual complexity ratings were obtained. These variables have been shown to be important for the selection of adequate stimuli for cognitive studies. Children's name agreement was lower than that of adults. The children also failed to provide adequate modal names for 103 concepts, rated drawings as less familiar and less complex, and chose shorter names for pictures. The differences in ratings between adults and children were higher than those observed in the literature employing smaller picture sets. The pattern of correlations among measures observed in the present study was consistent with previous reports, supporting the usefulness of the 400 picture set as a tool for cognitive research in different cultures and ages.KEY WORDS: picture, naming, familiarity, visual complexity, children, adults. Conjunto de 400 figuras padronizadas para o português: normas de nomeação, familiaridade e complexidade visual para crianças e adultosRESUMO -Este artigo fornece dados normativos para o Brasil de um conjunto de 400 figuras de objetos (Cycowicz et al., 1997) avaliados por estudantes universitários e crianças de 5-7 anos. Foram obtidos dados referentes à consistência de nomeação, familiaridade com os objetos representados e complexidade visual dos desenhos. Existem evidências de que essas variáveis são importantes para a adequada seleção de estímulos para estudos cognitivos. A consistência de nomeação das crianças foi menor que a dos adultos. Em relação aos adultos, as crianças não conseguiram nomear adequadamente 103 conceitos, avaliaram os desenhos como sendo menos familiares e menos complexos e escolheram nomes mais curtos para as figuras. As diferenças nas avaliações entre adultos e crianças foram mais altas que as observadas na literatura que envolveu conjuntos menores de desenhos. O padrão de correlações entre medidas observadas no presente trabalho são consistentes com relatos anteriores, o que dá suporte à utilidade desse conjunto de 400 figuras como ferramenta para pesquisas cognitivas em diferentes culturas e faixas etárias.

Exercise and physical training are known as promoters of several alterations, and among them, cardiorespiratory benefits, increase in the mineral bone density and decrease in the risk for chronic-degenerative diseases. Recently, another aspect has become notorious: an improvement in the cognitive function. Although it is very controversial, several studies have shown that physical exercises improve and protect the cerebral function, suggesting that physically active individuals present lower risk to develop mental disorders compared to sedentary individuals. This demonstrates that participating in physical exercise programs exerts benefits in the physical and psychological spheres, and it is probable that physically active individuals have a faster cognitive processing. Although the cognitive benefits of the physically active life-style seem to be related to the level of the regular physical activities, that is, exercises performed along the whole lifetime, suggesting a "cognitive reserve", it is never too late to start a physical exercise program. Thus, using physical exercises as an alternative to achieve an improvement in the cognitive function seems to be a aim to be attained mainly due to its applicability, since it is a relatively less expensive method that can be used by the major part of the population. Thus, the purpose of the present review is to discuss the associative aspects between physical exercises and the cognitive function, thus allowing to reflect on its use as an alternative and supportive element.

The phonological loop is a component of the working memory system specifically involved in the processing and manipulation of limited amounts of information of a sound-based phonological nature. Phonological memory can be assessed by the Children's Test of Nonword Repetition (CNRep) in English speakers but not in Portuguese speakers due to phonotactic differences between the two languages. The objectives of the present study were: 1) to develop the Brazilian Children's Test of Pseudoword Repetition (BCPR), a Portuguese version of the CNRep, and 2) to validate the BCPR by correlation with the Auditory Digit Span Test from the Stanford-Binet Intelligence Scale. The BCPR and Digit Span were assessed in 182 children aged 4-10 years, 84 from Minas Gerais State (42 from a rural region) and 98 from the city of São Paulo. There are subject age and word length effects causing repetition accuracy to decline as a function of the number of syllables of the pseudowords. Correlations between BCPR and Digit Span forward (r = 0.50; P ≤ 0.01) and backward (r = 0.43; P ≤ 0.01) were found, and partial correlation indicated that higher BCPR scores were associated with higher Digit Span scores. BCPR appears to depend more on schooling, while Digit Span was more related to development. The results demonstrate that the BCPR is a reliable measure of phonological working memory, similar to the CNRep.

Alzheimer’s disease (AD) is the most frequent cause of dementia. The clinical symptoms of AD begin with impairment of memory and executive function followed by the gradual involvement of other functions, such as language, semantic knowledge, abstract thinking, attention, and visuospatial abilities. Visuospatial function involves the identification of a stimulus and its location and can be impaired at the beginning of AD. The Visual Object and Space Perception (VOSP) battery evaluates visuospatial function, while minimizing the interference of other cognitive functions.ObjectivesTo evaluate visuospatial function in early AD patients using the VOSP and determine cutoff scores to differentiate between cognitively healthy individuals and AD patients.MethodsThirty-one patients with mild AD and forty-four healthy elderly were evaluated using a neuropsychological battery and the VOSP.ResultsIn the VOSP, the AD patients performed more poorly in all subtests examining object perception and in two subtests examining space perception (Number Location and Cube Analysis). The VOSP showed good accuracy and good correlation with tests measuring visuospatial function.ConclusionVisuospatial function is impaired in the early stages of AD. The VOSP battery is a sensitive battery test for visuospatial deficits with minimal interference by other cognitive functions.

RESUMO.O envelhecimento é um processo do desenvolvimento normal, envolvendo alterações neurobiológicas estruturais, funcionais e químicas. Também incidem sobre o organismo fatores ambientais e socioculturais -como qualidade e estilo de vida, dieta, sedentarismo e exercício -intimamente ligados ao envelhecimento sadio ou patológico. Este estudo teórico tem como objetivo ressaltar tópicos relevantes para o envelhecimento sadio e o envelhecimento doentio, fundamentados em resultados recentes da pesquisa em neurociências. Conclui-se que o aumento da idade não significa necessariamente adoecer; com medidas preventivas pode-se manter o idoso em condições saudáveis nos domínios físico e cognitivo, mantendo a autonomia de vida por longo período. Contudo, na presença de disfunções, o diagnóstico e a intervenção precoces podem propiciar uma melhor qualidade de vida ao paciente e sua família.Palavras-chave: envelhecimento, cognição, neurologia. AGING: A MULTIFACTORIAL PROCESSABSTRACT. Common sense designates the psychologist the most proficient professional to work with sexuality. Rarely, though, we are Ageing is a process of the normal development involving structural, functional and chemical neurobiological changes. The organism is affected also by environmental, cultural and social factors, as quality and style of life, diet, idleness, exercise, which are closely linked to healthy or pathological ageing. The objective of this theoretical paper is to stress some important issues about healthy and pathological ageing, based on recent research in neuroscience, which hallmarks the necessity of early diagnosis and intervention. In conclusion, growing older does not necessarily mean to get ill. Preventive measures can maintain the elder in healthy conditions for long, both in the physical and the cognitive domains and keeping his/her autonomy in life. However, in the presence of some dysfunction, early diagnosis and intervention can provide better quality of life for the patient and his/her family.Key words: Aging, cognition, neurology.

OBJECTIVE: To assess and compare the sensory processing abilities of children with Attention Deficit/Hyperactivity Disorder (ADHD) and children without disabilities, and to analyze the relationship between sensory processing difficulties and behavioural symptoms presented by children with ADHD. METHOD: Thirty-seven children with ADHD were compared with thirty-seven controls using a translated and adapted version of the "Sensory Profile" answered by the parents/caregivers. For the ADHD group, Sensory Profile scores were correlated to behavioural symptoms assessed using the Child Behaviour Check List (CBCL) and the Behavioural Teacher Rating Scale (EACI-P). The statistical analyses were conducted using the Mann Whitney test and Pearson correlation coefficients.RESULTS: Children with ADHD showed significant impairments compared to the control group in sensory processing and modulation, as well as in behavioural and emotional responses as observed in 11 out of 14 sections and 6 out of 9 factors. Differences in all Sensory Profile response patterns were also observed between the two groups of children. Sensory Profile scores showed a moderately negative correlation with CBCL and EACI-P scores in the ADHD group. CONCLUSION: These results indicate that children with ADHD may present sensory processing impairments, which may contribute to the inappropriate behavioural and learning responses displayed by children with ADHD. It also suggests the importance of understanding the sensory processing difficulties and its possible contribution to the ADHD symptomatology.
