Performance of normal adults on Rey Auditory Learning Test: a pilot study

Abstract

-The present study aimed to assess the performance of healthy Brazilian adults on the Rey Auditory Verbal Learning Test (RAVLT), a test devised for assessing memory, and to investigate the influence of the variables age, sex and education on the performance obtained, and finally to suggest scores which may be adopted for assessing memory with this instrument. The performance of 130 individuals, subdivided into groups according to age and education, was assessed. Overall performance decreased with age. Schooling presented a strong and positive relationship with scores on all subitems analyzed except learning, for which no influence was found. Mean scores of subitems analyzed did not differ significantly between men and women, except for the delayed recall subitem. This manuscript describes RAVLT scores according to age and education. In summary, this is a pilot study that presents a profile of Brazilian adults on A1, A7, recognition and LOT subitem.Key wORdS: memory, adult, evaluation. desempenho de indivíduos saudáveis no rey auditory Verbal learning test (raVlt): estudo piloto resumo -O objetivo deste estudo foi avaliar o desempenho de adultos normais brasileiros no Rey AuditoryVerbal Learning Test (RAVLT), um teste destinado à avaliação da memória, e investigar a influência das variáveis idade, sexo e escolaridade no desempenho obtido, além de sugerir escores que possam ser utilizados na avaliação da memória segundo este instrumento. Foi avaliado o desempenho de 130 indivíduos, subdivididos em grupos de acordo com a idade e escolaridade. O desempenho geral no teste diminuiu com o aumento da idade. A escolaridade apresentou relação forte e positiva com os escores em todos os subitens analisados, exceto no aprendizado, no qual não foi verificada influência. As médias dos escores dos subitens analisados não foram estatisticamente diferentes entre homens e mulheres, exceto no subitem recordação tardia. descrevemos os escores no RAVLT de acordo com faixa etária e escolaridade neste manuscrito. PALAVRAS-chAVe: memória, adulto, avaliação. Memory is defined as a group of abilities involving acquisition, storage and retrieval of different types of information 1 . Long-term memory allows the storage of large quantities of information for an indefinite period of time, while short-term memory is the ability to store small quantities of information for limited periods. Models representing memory and its subsystems incorporate the concept of working memory, defined as a memory system which involves temporary storage and manipulation of information for performing a wide variety of cognitive activities such as reasoning, comprehension, and repetitive tasks 2 . This system is divided into three interconnecting subsystems: the articulatory loop, visuo-spatial sketchpad and central executive. The articulatory loop is responsible for processing and temporarily retaining speech knowledge, and is made up of different components: a phonological store which retains the information in phonological code, and the articulatory p...

Evaluation of the Consonant Vowel Consonant (CVC) Test as an Assessment and Screening Instrument for Mild Cognitive Impairment

“…In general, the higher the education the more words were recalled. Similar results have been reported for word recall tasks (Donders, 2008;Messinis, Tsakona, Malefaki, & Papathanasopoulos, 2007;Norman, Evans, Miller, & Heaton, 2000;Teruya, Ortiz, & Minett, 2009).…”

Aplicação do teste M1-Alpha em sujeitos normais com baixa escolaridade: estudo piloto

“…Although two studies have been carried out, one involving a normal population (6) and the other an aphasic population (5) , a specific study in a population with low educational level was lacking. Schooling influences all cognitive functions (11,12) including language (4,13,14) , and the M1-Alpha comprises stimuli which can be easily processed by populations with low educational level (15,16) , largely owing to its visuallybased stimuli (17,18) . Given that individual and sociocultural factors can influence performance on language-based tasks, the aim of this study was to determine the performance of normal individuals with low educational level on the M1-Alpha test in order to obtain parameters for use in assessing aphasic patients with similarly low level of education.…”

Validade discriminante do Teste de Aprendizagem Auditivo-Verbal de Rey: comparação entre idosos normais e idosos na fase inicial da doença de Alzheimer

“…O estudo apresenta limitações no tamanho da amostra e em relação à diferença da frequência de homens e mulheres na amostra. Cabe salientar, entretanto, que o efeito do gênero no RAVLT é controverso, existindo dados que apontam para um melhor desempenho feminino em alguns itens do teste 11,18,[25][26][27][28] e outros que não encontraram tais diferenças 8,12,13,[29][30][31] . De forma a avaliar o papel do gênero no desempenho, subdividiu-se cada grupo em homens e mulheres, comparando seus desempenhos por meio do teste Mann--Whitney.…”
