We report the case of an 11-year-old boy who developed an anarithmetia in association with a left temporo-parietal tumor. His oral and written language were normal as well as his ability to judge magnitudes, process numbers, read operation signs and retrieve number facts. He had a specific difficulty in performing the procedures of subtraction, especially when it involved borrowing. These skills had been mastered before the present illness. This case shows that the components of calculation can be dissociated by brain lesions sustained during childhood, while arithmetic abilities are being acquired, thus reinforcing findings from developmental dyscalculias, that suggest a modular organisation of those skills during development.  相似文献

Differences in joint coordination between arms and due to aging were studied in healthy young and older adults reaching to either a fixed, central target or to the same target when it could unexpectedly change location after reach initiation. Joint coordination was investigated by artificially removing the covariation of each joint’s motions with other joints’ motions. Uncontrolled manifold analysis was used to partition joint configuration variance into variance reflecting motor abundance (VUCM) and variance causing hand path variability (VORT). The extent to which VORT, related to the consistency of the hand path, increased after removing a joint’s covariation indicated the strength of its coordination with other joints. Young adults exhibited stronger indices of joint coordination, evidenced by a larger increase in VORT after removing joint covariation than for older adults. This effect was more striking for the dominant right compared to the left arm for young adults, but not for older adults, especially with target uncertainty. The results indicate that interjoint coordination in young adults leads to less hand path variability compared to older adults.  相似文献

In study 1 (= 51, Mage = 21.4 years, SD = 5.7), the validity of the Portuguese adaptation of the Gudjonsson Suggestibility Scales ( Pires, 2011) was shown through the comparison of means of the original ( Gudjonsson, 1997) and the translated scales and the analysis of the correlations between the GSS1 and GSS2 scores. The relationships between interrogative suggestibility and the big five were also addressed and the results point to independence between suggestibility and personality, which is in line with Polczyk’s findings (2005). Study 2 (n = 87, Mage = 48.9 years, SD = 20.7) explored the relationships among interrogative suggestibility, the state–trait anxiety and demographic variables (i.e., age and gender). There were no significant relationships between anxiety and suggestibility. These results are in line with other studies that point to a lack of relationship between suggestibility and anxiety in normal samples (  and ). As for the relationships between age and interrogative suggestibility, ANCOVA confirmed that the increased suggestibility in old age was not due to age differences but rather to the limited memory capacity of the older adults group. There were no significant gender differences in the GSS1 subscales.  相似文献

This research shows that the same people who appear to have low numerical competence when analyzing personally irrelevant health-related numerical information are able to overcome their reasoning shortcomings and make better judgments when they are shown equivalent information that is personally relevant, and when only a sophisticated kind of reasoning enables them to interpret this information in a favorable way. The fact that people can engage in poorer or more sophisticated numerical reasoning depending on whether that reasoning produces favorable or unfavorable conclusions has implications both for the concept of numeracy as an individual-difference variable and for health communication.  相似文献

Alzheimer's disease (AD) is the 3rd most costly disease and the leading cause of dementia. It can linger for many years, but ultimately is fatal, the 6th leading cause of death. Alzheimer's disease (AD) is fatal and affected individuals can sometimes linger many years. Current treatments are palliative and transient, not disease modifying. This article reviews progress in the search to identify the primary AD-causing toxins. We summarize the shift from an initial focus on amyloid plaques to the contemporary concept that AD memory failure is caused by small soluble oligomers of the Aβ peptide, toxins that target and disrupt particular synapses. Evidence is presented that links Aβ oligomers to pathogenesis in animal models and humans, with reference to seminal discoveries from cell biology and new ideas concerning pathogenic mechanisms, including relationships to diabetes and Fragile X. These findings have established the oligomer hypothesis as a new molecular basis for the cause, diagnosis, and treatment of AD.  相似文献

The purpose of this study was to provide additional validity evidence for a model of person–environment fit based on polychronicity, stimulus load, and information processing capacities. In this line of research the confluence of polychronicity and information processing (e.g., the ability of individuals to process stimuli from the environment along five dimensions of information load, interpersonal load, change load, time structure, and activity structure) is applied to the occupational environment. Using magnitude estimation scaling, college students in the United States and Portugal rated 42 occupations across five information processing demand characteristics. Results indicated that occupations could be differentiated by the information load conditions, thus producing a profile of information processing demand characteristics unique to each of the occupations tested. Additional findings provided evidence for the validity of the scaled occupational values; ratings differed reliably across Holland categories, were fairly consistent across the two cultural groups, and showed expected relationships with salary and educational level.  相似文献

This study aimed to investigate the impact of seven environmental stressors (role conflict, work overload, interpersonal difficulties, work-family conflict, work instability, lack of autonomy and pressure of responsibility) and the nature of the employment contract (permanent or atypical) on three psychological reactions to occupational stress (job satisfaction, positive emotions, and negative emotions at work). 305 Brazilian workers from both sexes participated in this research, distributed between permanent and atypical workers. The results showed that the role conflict and the work overload had a negative impact on job satisfaction. The role conflict had a negative impact on the positive emotions at work, while the pressure of responsibility interfered positively in it. The work overload interfered positively in the negative emotions at work, while the pressure of responsibility interfered negatively in it. The type of contract did not affect significantly any one of the dependent variables. The implications of the results for future research are discussed.  相似文献

The present study conducted a preliminary examination of the psychometric properties of a recently developed Portuguese translation of the Acceptance of Cosmetic Surgery Scale (ACSS; Henderson-King & Henderson-King, 2005). A total of 311 Brazilian adults completed the ACSS along with Portuguese translations of measures of actual-ideal body weight discrepancy, body appreciation, sociocultural attitudes toward appearance, and demographics. Results showed that the Portuguese ACSS reduced to a three-factor solution consisting of the Intrapersonal, Social, and Consider factors uncovered in the original work using the ACSS. Moreover, there were only small sex differences on these subscales. In addition, the Portuguese ACSS showed a good pattern of convergent validity. The availability of the Portuguese ACSS is expected to stimulate more in-depth, quantitative research on attitudes toward cosmetic surgery within the Brazilian context.  相似文献

Considering that the intersexual condition has a negative impact on the individual, their family, and society, health professionals and researchers have dedicated themselves to is to describe and understand the perceptions of primary caregivers regarding intersexuality and its developmental aspects. Six mothers and one grandmother of school age children were interviewed. The data indicated that living with the stigma of intersexuality can mean a permanent state of crisis within the family system. Issues such as guilt about the child's suffering and questions related to the choice of gender follow the family from the moment of diagnosis. It is suggested that the therapeutic follow-up should foster the necessary conditions for the family group to be organized as a model of competence, replacing the model of guilt.  相似文献

In this article, we present an overview of the political context of vocational psychology and career counseling in Portugal. The essence of our position is that career counseling needs to encompass all the major tasks of personal and social development, beyond the traditional focus on primarily vocational/occupational goals. Given the importance of social and political factors that are apparent in an analysis of the Portuguese climate within career development, we propose that vocational psychology must go beyond a conceptualization of vocational behavior and intervention based on a person–environment fit model and must try to enhance strategies for the development of persons in a broader sense. We further propose that we need to provide career counseling not only at critical decision points, but throughout the life-span, and should not focus merely on occupational details, but on all matters of the development of the person as a whole. Finally, we suggest a perspective on career counseling and vocational psychology that is more responsive to our cultural and historical context and which is sensitive to the reality of a new political era in Portugal.  相似文献
