When individuals perform spatial tasks, individual differences emerge in accuracy and speed as well as in the response patterns used to cope with the task. The purpose of this study is to identify, through empirical criteria, the different response patterns or strategies used by individuals when performing the dynamic spatial task presented in the Spatial(More)
There is disagreement among researchers about the distinction between dynamic and static spatial performance. Given that dynamic spatial performance is supposed to be important for some occupations, such as air traffic control (ATC), it is germane to have evidence about the likelihood of that distinction. In the present study, a battery of printed static(More)
Computerized tasks allow a more fine-grained analysis of the strategy deployed in a task designed to map a specific ability than the usual assessment on the basis of only the level of performance. Manipulations expected to impair performance sometimes do not have that effect, probably because the level of performance alone can confound the assessment of the(More)
This study adapted a new task to assess visuospatial and verbal working memory impairments in patients with Alzheimer Disease (AD), including an executive strategy of information suppression. The aim was to examine the visuospatial and verbal difficulties, and additionally to explore the average sex differences, during a 2-year follow-up study. The results(More)
In the present study, the intuitive ability of police to discriminate between real and false statements of people with mild and moderate (IQ range=50-80, average=60.0) intellectual disabilities (ID) was analyzed. The assessments issued by groups with different levels of experience in police techniques (psychology students, and police officers) were(More)
The aim of this work was to analyze the effect of presentation format and instructions on the ability of people with intellectual disability to identify individuals they did not know and had seen only briefly. With this objective in mind, 2 groups of subjects with mild to moderate intellectual disability were shown a photograph of a person and, after a(More)
Males and females differ in several cognitive abilities, although the largest gap can be found in spatial ability. Some published studies make the claim that performance factors, which can be either subject- or task-related variables, explain these differences. However, previous studies in which performance factors were measured have focused on static(More)
BACKGROUND/AIMS To date, there are few studies on gender differences in patients with mild cognitive impairment (MCI) and Alzheimer disease (AD). In the present study, the existence of differences between sexes in verbal and visuospatial working memory tasks in the evolution of cognitive and pathological aging was examined. METHOD Ninety participants took(More)
Several experimental studies have shown that there exists an association between emotion words and the vertical spatial axis. However, the specific conditions under which this conceptual–physical interaction emerges are still unknown, and no study has been devised to test whether longer linguistic units than words can lead to a mapping of emotions on(More)
Given the importance of visuospatial processing in areas related to the STEM (Science, Technology, Engineering, and Mathematics) disciplines, where there is still a considerable gap in the area of sex differences, the interest in the effects of visuospatial skills training continues to grow. Therefore, we have evaluated the visuospatial improvement of(More)
