Schizophrenia is a severe mental illness affecting sense of identity. Autobiographical memory deficits observed in schizophrenia could contribute to this altered sense of identity. The ability to give a meaning to personally significant events (meaning making) is also critical for identity construction and self-coherence. Twenty-four patients with schizophrenia and 24 control participants were asked to recall five self-defining memories. We assessed meaning making in participants’ narratives (spontaneous meaning making) and afterwards asked them explicitly to give a meaning to their memories (cued meaning making). We found that both spontaneous and cued meaning making were impaired in patients with schizophrenia. This impairment was correlated with executive dysfunctions and level of negative symptoms. Our results suggest that patients’ difficulties in drawing lessons about past experiences could contribute to explain the lack of coherence observed in their life trajectories and their impaired social adjustment abilities. Implications for psychotherapy are also discussed. 相似文献

RSK2 is a Ser/Thr kinase acting in the Ras/MAPK pathway. Rsk2 gene deficiency leads to the Coffin-Lowry Syndrome, notably characterized by cognitive deficits. We found that mrsk2 knockout mice are unable to associate an aversive stimulus with context in a lithium-induced conditioned place aversion task requiring both high-order cognition and emotional processing. Virally mediated shRNA-RSK2 knockdown in the habenula, whose involvement in cognition is receiving increasing attention, also ablated contextual conditioning. RSK2 signaling in the habenula, therefore, is essential for this task. Our study reveals a novel role for RSK2 in cognitive processes and uncovers the critical implication of an intriguing brain structure in place aversion learning. 相似文献

We examined whether temporal integration of face parts reflects holistic processing or response interference. Participants
learned to name two faces “Fred” and two “Bob.” At test, the top and bottom halves of different faces formed composites and
were presented briefly separated in time. Replicating prior findings (Singer & Sheinberg, Vision Research, 46, 1838–1847, 2006), naming of the target half for aligned composites was slowed when the irrelevant half was from a face with a different name
rather than from the original face. However, no interference was observed when the irrelevant half had a name identical to
the name of the target half but came from a different learned face, arguing against a true holistic effect. Instead, response
interference was obtained when the target half briefly preceded the irrelevant half. Experiment 2 confirmed a double dissociation of holistic processing versus response interference for intact faces versus temporally separated
face halves, suggesting that simultaneous presentation of facial information is critical for holistic processing. 相似文献

The creation of the European Community by the Treaty of Rome in 1957 marked the beginning of the efforts to coordinate and harmonize national policies in many strategic sectors with high economic value, among them several aspects of scientific research. The European Union Law, formerly known as European Community law, now includes a range of ethical principles that apply to research projects developed with the financial support of the European Union. Which were the steps in the integration of the ethics of sciences in the context of the Union? This article aims to study first, what were, and what are the legal bases of the integration of the ethical dimension of researches in life sciences by the European Union and, secondly, the institutional organisation that has been set up in order to discuss the development of common ethical norms, especially bioethics one, and in order to apply these rules which respect national particularities. In this regard, we analyse the relevant legal texts providing a foundation for the creation of a European bio-law and we give an overview of the European institutions' activity in the field of bioethics by looking particularly the health research field. 相似文献

Both domain-specific and expertise accounts of category specialization assume that generalization occurs within a domain but not between domains. Yet it is often difficult to define the boundaries and critical features of object domains. Differences in how categories are defined make it difficult to adjudicate between accounts of category specificity and may lead to contradictory results. For example, evidence for whether car experts recruit the fusiform face area is mixed, and this inconsistency may be due to the inclusion of antique cars in one of those previous studies (e.g., Grill-Spector, Knouf, & Kanwisher, 2004). The present study tested the generalization of expertise from modern to antique cars and found that modern-car experts showed expert discrimination and holistic processing of modern cars but not of antique cars. These findings suggest that the neural specialization underlying perceptual expertise is highly specific and may not generalize to distinct subclasses, even when they share some degree of perceptual and conceptual features. 相似文献

On the basis of a review of the literature and the results of three experiments with dog experts, Robbins and McKone [Robbins, R. A., & McKone, E. (2006). No face-like processing for objects-of-expertise in three behavioural tasks, Cognition] argue that there is little or no evidence supporting an expertise account of the differences in configural processing that are typically observed between faces and non-face objects. In the spirit of a debate that has become overly polarized, we believe that R&M often emphasized relatively unimportant controversial issues at the expense of bigger, more important questions. We also feel that some of R&M's arguments are rooted in methodological confusions that should be clarified because they have implications beyond this specific debate. In this commentary, we first clarify issues surrounding the proper statistical analysis of the composite paradigm, a methodology that is commonly used to assess configural and holistic effects in both face and non-face objects. We then discuss several theoretical issues that we feel are central to the debate regarding accounts of face-specificity. We also briefly review positive evidence for the correlation between measures of behavioral expertise and neural markers of face-selectivity. Unlike R&M, we believe the positive evidence for expertise effects, both behavioral and neural, greatly outweighs evidence stemming from null results and that it clearly motivates the importance of future work on the role of experience in the specialization of visual cortex. 相似文献

What determines how much can be stored in visual short-term memory (VSTM)? Studies of VSTM have focused largely on stimulus-based properties such as the number or complexity of the items stored. Recent work also suggests that capacity is severely reduced for items within the same category. However, the importance for VSTM capacity of more qualitative differences in processing for different categories has not been investigated. For example, faces are processed more holistically than other objects. In Experiments 1 and 2, we show that the processing of faces, objects that are crucial socially and for which we possess considerable expertise, overcomes these limitations. More faces can be stored in VSTM than objects from other complex nonface categories. As in prior studies, at short encoding durations we found that capacity for faces was less than that for other categories. However, at longer encoding durations, capacity for faces exceeded that for nonface objects, and this advantage was specific to upright faces. Because inversion reduces holistic processing, the interaction of orientation with VSTM capacity—which occurred for faces but not objects in Experiment 3—suggests that it is holistic processing that confers an advantage for face VSTM when sufficient encoding time is allowed. 相似文献

This study used the Remember/Know (R/K) procedure combined with signal detection analyses to assess recognition memory in 20 elders with amnestic mild cognitive impairment (aMCI), 10 patients with probable Alzheimer’s disease (AD) as well as matched healthy older adults. Signal detection analyses first indicated that aMCI and control participants were comparable on general recognition performance. As regards AD patients, they were impaired relative to both aMCI and healthy elders. When assessing Remember and Know responses the aMCI group showed diminished sensitivity for Remember responses but intact Know responses compared to healthy elders. In contrast, AD patients showed decreased sensitivity for both Remember and Know responses compared to control and aMCI participants. The response bias index revealed that AD patients were more liberal than aMCI and control participants when providing Know responses. On the other measures, response bias was comparable between the groups. Overall, this study indicates that the R/K procedure can characterize different aspects of recognition memory performance in persons with aMCI or AD. 相似文献

In this article, an automated and accurate mouse observation method, based on a conventional test for motor function evaluation,
is outlined. The proposed measurement technique was integrated in a regular open-field test, where the trajectory and locomotion
of a free-moving mouse were measured simultaneously. The system setup consisted of a transparent cage and a camera placed
below it with its lens pointing upward, allowing for images to be captured from underneath the cage while the mouse was walking
on the transparent cage floor. Thus, additional information was obtained about the position of the limbs of the mice for gait
reconstruction. In a first step, the camera was calibrated as soon as it was fixed in place. A linear calibration factor,
relating distances in image coordinates to real-world dimensions, was determined. In a second step, the mouse was located
and its body contour segmented from the image by subtracting a previously taken “background” image of the empty cage from
the camera image. In a third step, the movement of the mouse was analyzed and its speed estimated from its location in the
past few images. If the speed was above a 1-sec threshold, the mouse was recognized to be running, and the image was further
processed for footprint recognition. In a fourth step, color filtering was applied within the recovered mouse region to measure
the position of the mouse’s paws, which were visible in the image as small pink spots. Paws that were detected at the same
location in a number of subsequent images were kept as footprints—that is, paws in contact with the cage floor. The footprints
were classified by their position relative to the mouse’s outline as corresponding to the front left or right paw or the hind
left or right paw. Finally, eight parameters were calculated from the footprint pattern to describe the locomotion of the
mouse: right/left overlap, front/hind base, right/left front limb stride, and right/left hind limb stride. As an application,
the system was tested using normal mice and mice displaying pentobarbital-induced ataxia. The footprint parameters measured
using the proposed system showed differences of 10% to 20% between normal and ataxic mice. 相似文献
