Should a history of child abuse be taken into consideration when a juvenile offender is punished? Although some research shows that child abuse is used as a mitigating factor for juvenile offenders (i.e., elicits less punitive sentences), surveys of juvenile court officials reveal that it is considered an aggravating factor. Specifically, in controlled mock jury studies in which child abuse is experimentally manipulated, child abuse elicits less punitive sentences. In contrast, child abuse elicits more punitive sentences in a nonexperimentally controlled environment—the juvenile justice system. This article provides a comprehensive literature review to explain these conflicting bodies of research by considering factors that naturally covary with childhood abuse: chaotic family environment, mental health problems, behavioral problems, and school problems.  相似文献

Four experiments investigated uncertainty about a premise in a deductive argument as a function of the expertise of the speaker and of the conversational context. The procedure mimicked everyday reasoning in that participants were not told that the premises were to be treated as certain. The results showed that the perceived likelihood of a conclusion was greater when the major or the minor premise was uttered by an expert rather than a novice (Experiment 1). The results also showed that uncertainty about the conclusion was higher when the major premise was uttered by a novice and an alternative premise by an expert, compared to when the major premise was uttered by an expert and the alternative by a novice (Experiment 2). Similarly, the believability of a conclusion was considerably lower when the minor premise was uttered by a novice and denied by an expert, as opposed to when an expert uttered the minor premise and a novice denied it (Experiment 3). Experiment 4 showed that the nature of the uncertainty induced by a denial of the minor premise depended on whether or not the context was a conversation. These results pose difficult problems for current theories of reasoning, as current theories are based on the results of experiments in which the premises are treated as certain. Our discussion of the results emphasises the importance of pragmatics in reasoning, namely, the role of general knowledge about the world in assessing the probability of a premise uttered by an expert or a novice and the role of interpretations of the premise based on pragmatic inferences in revising these initial probabilities.  相似文献

ABSTRACT

Objectives: This study examined the relationship between positive and negative affect, depressive symptoms, and cognitive performance. Methods: The sample consisted of 1479 non-demented, postmenopausal women (mean age = 67 years) at increased risk of breast cancer enrolled in the National Surgical Adjuvant Breast and Bowel Project’s Study of Tamoxifen and Raloxifene. At each annual visit, women completed a standardized neuropsychological battery and self-report measures of affect and depression. Data from three visits were used in linear mixed models for repeated measures using likelihood ratio tests. Separate analyses were performed to relate positive/negative affect and depression to each cognitive measure. Results: Higher positive affect was associated with better letter fluency (p = .006) and category fluency (p < .0001). Higher negative affect was associated with worse global cognitive function (p < .0001), verbal memory (CVLT List B; p = .002), and spatial ability (p < .0001). Depressive symptoms were negatively associated with verbal knowledge (p = .004), figural memory (p < .0001), and verbal memory (p’s ≤ .0001). Discussion: Findings are consistent with some prior research demonstrating a link between positive affect and increased verbal fluency and between depressive symptoms and decreased memory. The most novel finding shows that negative affect is related to decreased global cognition and visuospatial ability. Overall, this research in a large, longitudinal sample supports the notion that positive affect is related to increases and negative affect to decreases in performance on distinct cognitive measures.  相似文献

The meaningful consideration of cultural practices, values and beliefs is a necessary component in the effective translation of advancements in neuroscience to clinical practice and public discourse. Society’s immense investment in biomedical science and technology, in conjunction with an increasingly diverse socio-cultural landscape, necessitates the study of how potential discoveries in neurodegenerative diseases such as Alzheimer disease are perceived and utilized across cultures. Building on the work of neuroscientists, ethicists and philosophers, we argue that the growing field of neuroethics provides a pragmatic and constructive pathway to guide advancements in neuroscience in a manner that is culturally nuanced and relevant. Here we review a case study of one issue in culturally oriented neuroscience research where it is evident that traditional research ethics must be broadened and the values and needs of diverse populations considered for meaningful and relevant research practices. A global approach to neuroethics has the potential to furnish critical engagement with cultural considerations of advancements in neuroscience.  相似文献

In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics. Relationships between these objects of study can in turn be explored in three different ways: 1/ by a hermeneutic process, 2/ using statistics, the most frequent method in psychiatric research today, 3/ using equations, i.e. using mathematical relationships that are formal and deterministic. The 3 ways of representing entities (with language, locally with mathematics or globally with mathematics) and the 3 ways of expressing the relationships between entities (using hermeneutics, statistics or equations) can be combined in a cross-tabulation, and nearly all nine combinations can be described using examples. A typology of this nature may be useful in assessing which epistemological perspectives are currently dominant in a constantly evolving field such as psychiatry, and which other perspectives still need to be developed. It also contributes to undermining the overly simplistic and counterproductive beliefs that accompany the assumption of a Manichean “quantitative/qualitative” dichotomy. Systematic examination of this set of typologies could be useful in indicating new directions for future research beyond the quantitative/qualitative divide.  相似文献

This study tested men's perceptions of rape based on the belief that women use token resistance to sex—that they say "no" to sex when they really mean "yes." Participants were 131 male undergraduates who completed the Token Resistance to Sex scale and responded to evaluative statements regarding 1 of 3 scenarios: rape, consent, or ambiguous. Results supported the hypothesis that men with a weaker belief in token resistance would have stronger perceptions of rape when a woman said "no" to sex than when a woman said "yes," and that men with a stronger belief in token resistance would have weak perceptions of rape in both situations. These findings implicate miscommunication as a potential contributing factor in date rape.  相似文献

A variety of developmental accounts of intentionality, arising from disparate theoretical perspectives, can now be found in the literature. This paper argues that this diversity is undermining the ability of developmental psychologists to construct a coherent developmental account of the capacity and that it would be more productive to pursue an integrated approach. To this end, the dominant theoretical positions on the development of intentionality are reviewed and evaluated: intentionality as goal-directedness, a result of parental scaffolding, an innate capacity for intersubjectivity, and behavioral object-directedness. Particular attention is given to comparing three key features of each position: the definition of intentionality adopted, the types of behaviors considered to be evidence of intentionality, and the proposed developmental sequence. The possibility of constructing an integrated approach based on these components is explored.  相似文献

The high rates of suicide among older men are cause for concern, and have prompted the investigation of factors that might explain these elevated rates. The current research examined whether the gender role construct agency was associated with depression and suicidal ideation among older adults. The results, based on self‐report data from a sample of older Australian men (n = 69) and women (n = 90), indicated that depression mediated the relation between agency and suicidal ideation. In addition, for older men only, agency moderated the depression‐suicidal ideation relation. The results suggest that older adults, and particularly men, with low levels of agency should be the targets for interventions aimed at increasing levels of agency and improving mental health.  相似文献
