Our study examined age-related differences on a new memory test assessing memory for "who," "when," and "where," and associations among these elements. Participants were required to remember a sequence of pictures of different faces paired with different places. Older adults remembered significantly fewer correct face-place pairs in the correct sequence compared with young adults. Correlation a...

Older adults' susceptibility to misinformation in an eyewitness memory paradigm was examined in two experiments. Experiment 1 showed that older adults are more susceptible to interfering misinformation than are younger adults on two different tests (old-new recognition and source monitoring). Experiment 2 examined the extent to which processes associated with frontal lobe functioning underlie o...

Conation has been defined as the ability to focus and maintain intellectual energy over time. Prior research has shown that conation contributes to the magnitude of differences in test scores among brain-damaged and non-brain-damaged examinees. The purpose of the current investigation was to determine if conation might similarly account for differences in test scores among performance valid and...

In the Advanced Neuropsychological Diagnostics Infrastructure (ANDI), datasets of several research groups are combined into a single database, containing scores on neuropsychological tests from healthy participants. For most popular neuropsychological tests the quantity, and range of these data surpasses that of traditional normative data, thereby enabling more accurate neuropsychological asses...

We analyzed the influence of education and of culture on the neuropsychological profile of an indigenous and a nonindigenous population. The sample included 27 individuals divided into four groups: (a) seven illiterate Maya indigenous participants, (b) six illiterate Pame indigenous participants, (c) seven nonindigenous participants with no education, and (d) seven Maya indigenous participants ...

BACKGROUND Empirical studies of rationality (syllogisms) in patients with schizophrenia have obtained different results. One study found that patients reason more logically if the syllogism is presented through an unusual content. AIMS To explore syllogism-based rationality in schizophrenia. METHOD Thirty-eight first-admitted patients with schizophrenia and 38 healthy controls solved 29 syl...

A. R. Luria's approach to neuropsychological assessment was examined. Three basic points of departure from Luria are presented: his interpretation of cognitive activity as functional systems, his emphasis on the individualized approach, and the importance of the analysis of the errors. A distinction was introduced between Luria's neuropsychological testing, and Luria's neuropsychological approa...

higher high exposure. Thirteen neuropsychological tests evaluated cognitive, motor, and four evaluated affective aspects. Results Means were for: age 35(9.14) years; time working at the company 8(8.6) years. In the multiple linear regression models decreased function was confirmed only for two tests: trailmaking A (R = 12.3%) and Pursuit aiming II (R = 19.5%). Age contributed to this and higher...

The assessment of memory typically includes tests for both audioverbal and visuospatial processing, while measurements of learning have primarily utilized the audioverbal mode. However, there exists no compelling reason why learning should not also be assessed in the visuospatial mode. The Ruff Light Trail Learning Test (RULIT) represents such an option. Normative values utilizing 307 volunteer...

Racial differences on mental test scores are some of the most well-documented findings in the study of individual differences, yet only in the past 10 years have neuropsychologists undertaken serious examination of ethnic and related demographic concomitants of neuropsychological test performance. The present study examined performance differences for blacks and whites on 14 separate measures o...
