Here we apply a method for automated segmentation of the hippocampus in 3D high-resolution structural brain MRI scans. One hundred and four healthy young adults completed twenty one tasks measuring abstract, verbal, and spatial intelligence, along with working memory, executive control, attention, and processing speed. After permutation tests corrected for multiple comparisons across vertices (p < .05), significant relationships were found for spatial intelligence, spatial working memory, and spatial executive control. Interactions with sex revealed significant relationships with the general factor of intelligence (g), along with abstract and spatial intelligence. These correlations were mainly positive for males but negative for females, which might support the efficiency hypothesis in women. Verbal intelligence, attention, and processing speed were not related to hippocampal structural differences. 相似文献

The heterogeneity of schizophrenia remains an obstacle for understanding its pathophysiology. Studies using a tone discrimination screening test to classify patients have found evidence for 2 subgroups having either a specific deficit in verbal working memory (WM) or deficits in both verbal and nonverbal memory. This study aimed to (a) replicate in larger samples differences between these subgroups in auditory verbal WM; (b) evaluate their performance on tests of explicit memory and sustained attention; (c) determine the relation of verbal WM deficits to auditory hallucinations and other symptoms; and (d) examine medication effects. The verbal WM and tone discrimination performance did not differ between medicated (n = 45) and unmedicated (n = 38) patients. Patients with schizophrenia who passed the tone screening test (discriminators; n = 60) were compared with those who did not (nondiscriminators; n = 23) and healthy controls (n = 47). The discriminator subgroup showed poorer verbal WM than did controls and a deficit in verbal but not visual memory on the Wechsler Memory Scale-Revised (Wechsler, 1987), whereas the nondiscriminator subgroup showed overall poorer performance on both verbal and nonverbal tests and a marked deficit in sustained attention. Verbal WM deficits in discriminators were correlated with auditory hallucinations but not with negative symptoms. The results are consistent with a verbal memory deficit in a subgroup of schizophrenia having intact auditory perception, which may stem from dysfunction of language-related cortical regions, and a more generalized cognitive deficit in a subgroup having auditory perceptual and attentional dysfunction. 相似文献

Studies on migration have focused on obstacles and barriers encountered by migrants when they arrive in a new country. Recognizing that there are difficulties, it is also important to know the resources used by migrants to overcome adversity. This study springs from a theoretical perspective of resilience, based on a culturally significant ecological model (Ungar M, Resilience across Cultures. British Journal of Social Work, 38(2), 218–235, 2008) to analyze the processes of cultural adjustment to the host country in migratory movements. Thus, it seeks to understand the various dynamics in adversity and in resources experienced by migrants in Portugal originated from Portuguese-speaking countries (Guinea, Cape Verde, Brazil, Angola, Mozambique). To this end, seven focus groups (N?=?35) were facilitated for a discussion on the dimensions of resilience processes. The thematic analysis revealed five main themes in the adversity dimension with some of its topics further grouped in specific sub-topics. In the resources dimension, four salient themes have emerged. Data was discussed in an articulated perspective of themes, illustrating some of the difficulties and resources of migrants in the specificity of the Portuguese context. Implications for research on resilience are highlighted, and some bridges are built for the context of intervention in migrant integration. 相似文献

Proper n-valued ukasiewicz algebras are obtained by adding some binary operators, fulfilling some simple equations, to the fundamental operations of n-valued ukasiewicz algebras. They are the s-algebras corresponding to an axiomatization of ukasiewicz n-valued propositional calculus that is an extention of the intuitionistic calculus.Dedicated to the memory of Gregorius C.

The problem of distance from the truth, and more generally distance between hypotheses, is considered here with respect to the case of quantitative hypotheses concerning the value of a given scientific quantity.Our main goal consists in the explication of the concept of distance D(I, ) between an interval hypothesis I and a point hypothesis . In particular, we attempt to give an axiomatic foundation of this notion on the basis of a small number of adequacy conditions.Moreover, the distance function introduced here is employed for the reformulation of the approach to scientific inference — developed by Hintikka, Levi and other scholars — labelled cognitive decision theory. In this connection, we supply a concrete illustration of the rules for inductive acceptance of interval hypotheses that can be obtained on the basis of D(I, ).Lastly, our approach is compared with other proposals made in literature about verisimilitude and distance from the truth.I am grateful for the possibility of spending a period of some months at the Department of Philosophy of University of Gröningen. I profited there a lot from the supervision by Dr. Theo Kuipers. I am also grateful to Prof. Ilkka Niiniluoto who gave rise to my interest in this kind of research during a period spent at Department of Philosophy of University of Helsinki, and who made a number of useful suggestions in the final stage of this paper. Moreover, I would like to thank Dr. Carlo Buttasi for suggesting a better formulation of the proof of (T.24). 相似文献

This article surveys the output of contemporary Italian philosophers and distinguishes three principal ways of approaching
their intellectual endeavor: denial, the “evil-queen syndrome,” and compliance. Philosophers in a state of denial seem unaware
of the loss in status that Italian philosophy as an academic discipline suffers in international forums. The evil-queen syndrome
concerns the habit of compiling surveys of past philosophies, focusing on traditions of which one considers oneself the privileged
inheritor. Compliance—in its commendable aspect—refers to the growing number of philosophers who participate in international
debates, whose forums are for the most part Anglo-American peer-refereed journals. This article urges a less subservient intellectual
attitude, capable of contributing new ideas and arguments to the international philosophical forum. 相似文献

The Minnesota Multiphasic Personality Inventory–2 (MMPI-2) is frequently used by professional counselors to assess Chicano or Mexican American clients in various mental health settings. It is important to understand how ethnic and sociocultural variables (e.g., ethnic identity, acculturation, or racism) may influence the assessment process. This article presents strategies for the culturally competent use of the MMPI-2 with this burgeoning Hispanic subpopulation. 相似文献

The Perception of the Other in International Relations: Evidence for the Polarizing Effect of Entitativity 总被引:1,自引:0,他引:1
In an international relations context, the mutual images held by actors affect their mutual expectations about the Other's behavior and guide the interpretation of the Other's actions. Here it is argued that the effect of these images is moderated by the degree of entitativity of the Other—that is, the extent to which it is perceived as a real entity. Two studies tested this hypothesis by manipulating the entitativity of the European Union (EU) among U.S. citizens whose images of the EU varied along the enemy/ally dimension. Results of these studies yielded converging evidence in support of the hypothesized moderating effect of entitativity. Specifically, entitativity showed a polarizing effect on the relationship between the image of the EU and judgments of harmfulness of actions carried out by the EU. 相似文献

One of the major transformations in religion in contemporary societies has been the decline of church institutions and their reconstruction within a diverse network of associations, therapies, markets and other unconventional spiritual services. Based on extensive ethnographic fieldwork on religious behaviours and dynamics in sports contexts, and taking the similarities between sport and religion as the point of departure, this paper analyses, reflects on and theorises about the symbolic affinities of these two contemporary social institutions. The results show that symbolism converges in the religious element, tending to improve aspects related to sports ethics and establishing affective experiences among participants, with positive results for their physical and mental wellbeing. The findings indicate that a symbolic analysis of the various facets of sport is a useful approach for gaining a better understanding of this phenomenon, since besides being biological, diseases are also cultural and social, and thus, disease, religion and ritual are emotionally related. 相似文献
