Recent research highlights the importance of motor processes for a wide range of cognitive functions such as object perception and language comprehension. It is unclear, however, whether the involvement of the motor system goes beyond the processing of information that is gathered through active action experiences and affects also the representation of knowledge acquired through verbal learning. We tested this prediction by varying the presence of motor interference (i.e., squeezing a ball vs. oddball detection task) while participants verbally acquired functional object knowledge and examined the effects on a subsequent object detection task. Results revealed that learning of functional object knowledge was only impaired when participants performed an effector-specific motor task while training. The present finding of an effector-specific motor interference effect on object learning demonstrates the crucial role of the motor system in the acquisition of novel object knowledge and provides support for an embodied account to perception and cognition.  相似文献

Studies of elementary calculation have shown that adults solve basic subtraction problems faster with problems presented in addition format (e.g., 6?+?_?=?13) than in standard subtraction format (e.g., 13 – 6?=?_). Therefore, it is considered that adults solve subtraction problems by reference to the inverse operation (e.g., for 13 – 6?=?7, “I know that 13 is 6?+?7”) because presenting the subtraction problem in addition format does not require the mental rearrangement of the problem elements into the addition format. In two experiments, we examine whether adults' use of addition to solve subtractions is modulated by the arrangement of minuend and subtrahend, regardless of format. To this end, we used arithmetic word problems since single-digit problems in subtraction format would not allow the subtrahend to appear before the minuend. In Experiment 1, subtractions were presented by arranging minuend and subtrahend according to previous research. In Experiment 2, operands were reversed. The overall results showed that participants benefited from word problems where the subtrahend appears before the minuend, including subtractions in standard subtraction format. These findings add to a growing body of literature that emphasizes the role of inverse reference in adults' performance on subtractions.  相似文献

为探讨被动性社交网站使用、冗思、核心自我评价与初中生抑郁的关系,本研究采用被动性社交网站使用问卷、冗思问卷、核心自我评价问卷以及流调中心用抑郁量表对673名初中生进行调查研究。结果显示:(1)被动性社交网站使用与冗思和抑郁均呈显著正相关,而与核心自我评价呈显著负相关;核心自我评价与冗思、抑郁呈显著负相关;冗思与抑郁呈显著正相关;(2)被动性社交网站使用不仅对初中生抑郁具有显著的直接预测作用,而且能够通过三种间接效应对抑郁产生影响,即核心自我评价的单独中介作用、冗思的单独中介作用以及二者的链式中介作用。  相似文献

Cirrhosis secondary to alcohol use is a primary cause of liver disease and a medical condition for which liver transplantation is a viable treatment option. However, there remains considerable debate within both the lay and the medical communities regarding the distribution of a scarce medical resource to adults with alcoholism. This study examined college students' perceptions toward an adult, presented in a written vignette, for whom liver transplantation was medically indicated. The influence of gender (female and male) and alcohol use history (no alcohol history, alcoholism history with long-term abstinence, alcoholism history with current use) on these ratings was examined. Subjects rated the adult presented with no alcohol history more positively than they did the adults presented with a history of alcoholism. Also, the adult with no alcohol history was more likely to be offered transplantation and was given higher priority ratings for transplantation by subjects. While subjects' own alcohol use history and organ donor registration status were not associated with ratings, having a family member with an alcohol problem and personally knowing a transplant recipient were related to more favorable ratings toward the adult presented in the vignette. Implications of these findings as well as limitations of the study are discussed.  相似文献

The Vanderbilt Caregiver Empowerment Project evaluated a training program designed to enhance empowerment of caregiver and their subsequent involvement in the mental health treatment of their children. The intervention utilized a multi-component parent training curriculum that was designed to enhance: (a) knowledge of the service system; (b) skills needed to interact with the mental health system; and (c) the caregiver' s mental health services self-efficacy designed to improve caregivers beliefs in their ability to collaborate with service providers. The resulting increased empowerment was hypothesized to increase caretaker involvement, which should affect service use and ultimately the mental health status of the child. A randomized design was used to test the effectiveness of this model with caregivers of children receiving mental health services. The results one-year after the training replicated the intermediate outcomes of the project conducted 3-months after the training. The initial training continued to significantly influence the parent's knowledge and mental health services self-efficacy. However, the intervention had no effect on caregiver involvement in treatment, service use or the mental health status of the children.  相似文献

Filing charges of scientific misconduct can be a risky and dangerous endeavor. This article presents rules of conduct to follow when considering whether to report perceived misconduct, and a set of step-by-step procedures for responsible whistleblowing that describe how to do so once the decision to report misconduct has been made. This advice is framed within the university setting, and may not apply fully in industrial settings. Ms. Gunsalus, an attorney, has been responsible for a wide range of compliance issues and academic policy matters at her university including responding to allegations of scientific misconduct. She served on the United States Commission on Research Integrity and spent six years on the AAAS Committee on Scientific Freedom and Responsibility, four of them as chair. An earlier version of this paper was presented at the symposium entitled “Damned If You Do, Damned If You Don’t: What the Scientific Community Can Do About Whistleblowing” held during the Annual Meeting of the AAAS, Seattle, Washington, 15 February, 1997.  相似文献

“The Use of an Object and Relating through Identifications” (1968) represents Donald Winnicott's theoretical and clinical legacy. The author develops this concept from a clinical point of view, through the analysis of a woman with psychotic functioning. He reflects upon the dramatic quality of risks inherent in the processes linked to the use of the object with seriously disturbed patients. He explores different meanings of the analyst's survival, linking it to the analyst's response. The processes of the use of the object—that is, the encounter between the patient's potential destructiveness and the analyst's capacity to respond through his own judicious subjectivity—let the patient experience the analyst's capacity to keep his own subjectivity, authenticity, and creativity alive. It is starting from the traces of this live object that patients gradually form their own personal sense of being real.  相似文献

Screening, brief intervention, and referral to treatment (SBIRT) is a flexible, evidence‐based approach to assessing risk and providing brief interventions for individuals with alcohol use disorders. This article identifies 3 diverse populations that could benefit from universal screening—a foundation of SBIRT—and provides resources and support for implementation across a broad range of settings.  相似文献
