Modern cognitive neuroscientific theories and empirical evidence suggest that brain structures involved in movement may be related to action-related semantic knowledge. To test this hypothesis, we examined the naming of environmental sounds in patients with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP), two neurodegenerative diseases associated with cognitive and motor deficits. Subjects were presented with 56 environmental sounds: 28 sounds were of objects that required manipulation when producing the sound, and 28 sounds were of objects that required no manipulation. Subjects were asked to provide the name of the object that produced the sound and also complete a sound-picture matching condition. Subjects included 33 individuals from four groups: CBD/PSP, Alzheimer disease, frontotemporal dementia, and normal controls. We hypothesized that CBD/PSP patients would exhibit impaired naming performance compared with controls, but the impairment would be most apparent when naming sounds associated with actions. We also explored neural correlates of naming environmental sounds using voxel-based morphometry (VBM) of brain MRI. As expected, CBD/PSP patients scored lower on environmental sounds naming (p < 0.007) compared with the controls. In particular, the CBD/PSP patients scored the lowest when naming sounds of manipulable objects (p < 0.05), but did not show deficits in naming sounds of non-manipulable objects. VBM analysis across all groups showed that performance in naming sounds of manipulable objects correlated with atrophy in the left pre-motor region, extending from area six to the middle and superior frontal gyrus. These results indicate an association between impairment in the retrieval of action-related names and the motor system, and suggest that difficulty in naming manipulable sounds may be related to atrophy in the pre-motor cortex. Our results support the hypothesis that retrieval of action-related semantic knowledge involves motor regions in the brain. 相似文献

Personality disorder (PD) increases risk for suicidal behavior. Certain life events (LE) can precipitate suicidal behaviors in patients with PD. A fundamental question is whether specific combinations of LE and PD increase suicidal risk. Four hundred forty-six suicide attempters (SA) were recruited from emergency rooms. We used a healthy control group (n = 515) to identify the best cut-off point for the instrument used to diagnose PD. We used the DSM-IV version of the International Personality Disorder Questionnaire-Screening Questionnaire, the Mini International Neuropsychiatric Interview, and the Social Adjustment Scale to assess PD, Axis I disorders, and LE, respectively. After controlling for Axis I disorders, we found that "Death of spouse" preceded suicidal acts in those with antisocial PD (FET p = 0.024) and patients with narcissistic PD attempted suicide after being Fired at work (FET p = 0.002), among others. Our data suggest the presence of particular LE-PD associations in suicide attempters. Some LE-PD relationships appear independent of Axis I disorders in suicide attempters. This may offer a basis for specific targeted therapies or prevention programs aimed at decreasing suicidal risk. 相似文献

Two experiments examined whether time‐based prospective memory performance is influenced by the continuous or discontinuous nature of an ongoing activity. The first experiment demonstrated that prospective memory performance was not influenced by the engagement in continuous or discontinuous ongoing activity. The second experiment demonstrated that a discontinuous ongoing activity negatively affected prospective memory performance when participants had to execute two time‐based tasks for which the retention intervals partially overlapped. The results suggest that when individuals are engaged in multiple time‐based tasks, a general timing disruption occurs, with a proactive interference effect resulting in costs that are detrimental to prospective timing.

The predictive utility of social cognitive career theory’s (SCCT) interest and choice models was examined in a sample of 600 Portuguese high school students. Participants completed measures of occupational self-efficacy, outcome expectations, interests, social supports and barriers, and choice consideration across the six Holland (1997) RIASEC types. The integrated interest-choice model fit the data well across Holland types and generally supported the hypotheses that self-efficacy and outcome expectations jointly predict interests, and that interests mediate the relations of self-efficacy and outcome expectations to choice consideration. Contrary to SCCT, however, social supports and barriers related to choice consideration indirectly, through self-efficacy, rather than directly. The implications of these findings for further research on the cross-cultural validity of SCCT are considered. 相似文献

Not all Latino men and women conform to proscribed gender roles. Nonetheless, their sexual risk taking may well be influenced by traditional beliefs concerning these roles. We explored the relationship between gender beliefs that are normative in Latino culture, and the sexual risk behaviors of 152 Latino men and women who participated in a behavioral rapid needs assessment survey in Houston, TX. Path—analytic results indicate that normative gender beliefs are influenced by respondents' sex and their levels of acculturation and that these 2 variables influence sexual risk behaviors, including unprotected sex and multi partnerism. Our results suggest that beliefs about gender influence sexual behavior and, therefore, are an important factor that should be considered in understanding sexual risk taking among Latinos. 相似文献

Aims: Drawing on their engagement in a specific collective biography research project, the co-authors aim to demonstrate how the weaving together of creative story-telling and the theory underlining collective biography practices resulted in an understanding of rhizomatic research methodologies from within the process. This paper aims to demonstrate one way in which research methodologies training can become more firmly embedded within counsellor training courses. Method: A collective of counselling students and a session tutor colleague used collective biography practices to research their memories of traversing the liminal space between ‘counsellor’ and ‘counselling researcher’. Alongside the resulting collective stories, a collaborative review of the research process examined our chosen ways of working within the project. Outcomes: Engaging in collective biography practices resulted in an experiential shift from ‘learning to do counselling research’ to ‘becoming counselling researchers’. Weaving together research processes and researcher reflexivity generated personal and professional learning. Ways in which these research methodologies complement core components of counselling training, within and beyond the teaching of research, were identified. Conclusions: Collective biography practices offer a way of introducing non-arboreal creative research methodologies into counsellor training. Careful consideration of potential challenges surrounding the introduction of these practices is required. 相似文献

This study investigates the effects of accuracy motivation and need to evaluate on online vs. memory-based attitude formation and attitude–behavior consistency. Results show that online attitude formation is more likely when accuracy motivation or the need to evaluate is high. However, cognitive load disrupts online attitude formation even when accuracy motivation is high. Additionally, attitude relevance increases the likelihood of online attitude formation, but attitude accessibility does not. Furthermore, online (vs. memory-based) attitudes are more predictive of subsequent non-hypothetical choice. 相似文献

There are certain kinds of risk for which governments, rather than individual actors, are increasingly held responsible. This
article discusses how regulatory institutions can ensure an equitable distribution of risk between various groups such as
rich and poor, and present and future generations. It focuses on cases of risk associated with technological and biotechnological
innovation. After discussing various possibilities and difficulties of distribution, this article proposes a non-welfarist
understanding of risk as a burden of cooperation. 相似文献

On Interaction Analysis and Dialogical Perspective: Emergent Patterns of Order and Relational Agency
Maria C. D. P. Lyra 《Integrative psychological & behavioral science》2010,44(3):273-280
This essay proposes to contribute with a continuing discussion on Grossen’s paper (2010) establishing a link between the analysis of interactions and dialogical perspective using what I call simplication-for-approaching-complexity
(SFAC). This approach conceives of dialogical dynamics as a dynamic system of relationship that construct patterns. Moreover,
these emergent patterns allow inferring the features of dialogical partners as relational agencies. The specific characteristics
of the relational agency at any moment in dialogue can be inferred from the analysis of the specific pattern of order achieved
by the historical development of dialogue. This proposal is illustrated by the analysis of mother-infant interactions. 相似文献

Social motivation has been shown to influence various cognitive processes. In the present paper, it is verified that people are motivated to view out‐groups as possessing a lesser degree of humanity than the in‐group (Leyens et al., 2000 ) and that this motivation influences logical processing in the Wason selection task. So far, studies on infra‐humanization have been shown to influence attribution of uniquely human characteristics to groups. Most of these studies focused on the attribution of secondary emotions. Results have shown that secondary emotions are preferentially attributed to in‐group members (Leyens et al., 2001 ). Also, people tend to react differently to in‐group and out‐group members displaying secondary emotions (Gaunt, Leyens, & Sindic, 2004 ; Vaes, Paladino, Castelli, Leyens, & Giovanazzi, 2003 ). In the present paper, it is argued that infra‐humanization is a two‐direction bias and that it does influence logical processing among perceivers. Specifically, infra‐humanization motivation impacts logical processing in two different directions. First, most motivation is spent to reach the desirable conclusion that the in‐group is uniquely human. Second, least motivation occurs to support the undesirable conclusion that the out‐group is uniquely human. These hypotheses are tested in four cross‐cultural studies that varied the status and the conflicting relations between groups. Results were in line with the predictions and further confirmed that infra‐humanization biases can be obtained independently of status and conflict (but see Cortes, Demoulin, Leyens, & de Renesse, 2005 ). The discussion relates these findings with in‐group favouritism and out‐group derogation (Brewer, 1999 ) and underlines the importance of infra‐humanization in counteracting system justification biases (Jost & Banaji, 1994 ). 相似文献
