The amygdala has been described as a structure affected by mesial temporal lobe epilepsy (MTLE). Indeed, it is suggested that amygdala abnormalities are related to the co-morbid depression and anxiety reported in MTLE. In this context, we investigated the relation between functional connectivity (FC) emerging from this structure in fMRI and depression and anxiety levels reported in MTLE patients. We focused on resting-state BOLD activity and evaluated whether FC differences emerge from each of three amygdala subdivisions (laterobasal, centromedial and superficial) in left and right MTLE groups, compared with healthy controls. Results revealed significant differences between patient groups and controls. Specifically, the left MTLE group showed abnormal FC for the left-sided seeds only. Furthermore, regardless of the seed, we observed more reliable differences between the right MTLE group and controls. Further analysis of these results revealed correlations between these impaired connectivities and psychiatric symptoms in both MTLE groups. Opposite relations, however, were highlighted: the more depressed or anxious the right MTLE patients, the closer their FC values approached controls; whereas the less anxious the left MTLE patients, the closer their FC values were normative. These results highlight how MTLE alter FC emerging from the limbic system. Overall, our data demonstrate that right TLE has a more maladaptive impact on emotion-related networks, in ways specific to the amygdala region, and the emotion symptom involved, than left TLE. 相似文献

ABSTRACT This article reports a visitor observation study that was conducted at the aquarium of Rotterdam Zoo, called the Oceanium. Observations were performed in six different aquarium exhibits within the Oceanium and visitors' stopping and watching behaviors were recorded. Results showed that in five out of six exhibits, visitors were more likely to stop and watch during the morning than in the afternoon. This study provided evidence regarding visitors' use of different exhibits, which will be valuable in improving both the recreational and educational value of the experiences offered at the Oceanium. 相似文献

This study examined if attachment patterns mediated the link between childhood maltreatment and total daily and interpersonally oriented life hassles in 135 low-income, inner-city, suicidal African American women. Participants completed self-report measures of childhood maltreatment, attachment styles, and daily life hassles dimensions. Bootstrapping analyses revealed that (a) negative views of self mediated the relationship between childhood maltreatment and social and cultural difficulties and social acceptability; and (b) negative views of other mediated the relationship between childhood maltreatment and total daily life hassles, social victimization, and social and cultural difficulties. These findings can inform interventions for suicidal African American women with a history of childhood maltreatment and subsequent maladaptive attachment styles. 相似文献

The utterance of a negative statement invites the pragmatic inference that some reason exists for the proposition it negates to be true; this pragmatic inference paves the way for the logically unexpected Modus Shmollens inference: “If p then q; not-q; therefore, p.” Experiment 1 shows that a majority of reasoners endorse Modus Shmollens from an explicit major conditional premise and a negative utterance as a minor premise: e.g., reasoners conclude that “the soup tastes like garlic” from the premises “If a soup tastes like garlic, then there is garlic in the soup; Carole tells Didier that there is no garlic in the soup they are eating.” Experiment 2 shows that this effect is mediated by the derivation of a pragmatic inference from negation. We discuss how theories of conditional reasoning can integrate such a pragmatic effect. 相似文献

Investigations of neurodegenerative disorders may reveal functional relationships in the cognitive system. C.S. was a 63‐year‐old right‐handed man with post‐mortem confirmed Pick's disease with a range of progressive impairments including non‐fluent aphasia, speech, limb, oculomotor, and buccofacial apraxia, but mostly intact intelligence, perception, orientation, memory, semantics, and phonology. During progression, agrammatism in writing with impairments in syntactic comprehension emerged in parallel with an unusual graphomotor deficit in drawing and writing, with an increasing deterioration of graphic short‐term memory. We investigated C.S.'s graphomotor deficit longitudinally using tests of writing and drawing on letters, words, and sentences and drawing to command and copying. We also tested C.S.'s short‐term graphemic buffer experimentally. Analysis showed deficits on selective aspects of graphomotor implementation of writing and drawing, mainly affecting the production of circles and curves, but not short straight lines in drawing and writing, and graphomotor short‐term memory, which paralleled impairments of written syntax and syntactic comprehension. We believe this to be the first detailed analysis of such an unusual progressive impairment in graphomotor production, which may be related to problems with agrammatic agraphia and impairments affecting shared components of cognition reflecting damage to shared neural networks. Alternatively, they may simply reflect the effects of coincidental damage to separate mechanisms responsible for aspects of writing, drawing, and syntactic processing. Longitudinal investigations of emerging deficits in progressive conditions like C.S.'s provides an opportunity to examine the progressive emergence of symptoms in an individual with multiple progressive impairments as they appear and examine putative relationships between them. 相似文献

This paper reports a study that used a quasi-experimental design to examine if a career intervention designed to increase self-knowledge enabled self-discovery or self-construction, determined by the structure of the personality inventory used. This study, situated within the theoretical model of Markus’s research in self-schemata (1977), used instruments that measured the Big Five personality factors. Results showed that after only one exercise designed to increase self-knowledge, high school students in the experimental group elaborated “self-schemata” that encompassed the five dimensions corresponding to the structure of the instrument used. Findings suggested that the self-knowledge tool constituted a sort of structured “looking glass” in which young people saw themselves reflected according to the dimensions in the inventory used. 相似文献

Individuals tend to select again alternatives about which they have positive impressions and to avoid alternatives about which they have negative impressions. Here we show how this sequential sampling feature of the information acquisition process leads to the emergence of an illusory correlation between estimates of the attributes of multi-attribute alternatives. The sign of the illusory correlation depends on how the decision maker combines estimates in making her sampling decisions. A positive illusory correlation emerges when evaluations are compensatory or disjunctive and a negative illusory correlation can emerge when evaluations are conjunctive. Our theory provides an alternative explanation for illusory correlations that does not rely on biased information processing nor selective attention to different pieces of information. It provides a new perspective on several well-established empirical phenomena such as the ‘Halo’ effect in personality perception, the relation between proximity and attitudes, and the in-group out-group bias in stereotype formation. 相似文献

Jean Piaget’s theory is a central reference point in the study of logico-mathematical development in children. One of the most famous Piagetian tasks is number conservation. Failures and successes in this task reveal two fundamental stages in children’s thinking and judgment, shifting at approximately 7 years of age from visuospatial intuition to number conservation. In the current study, preschool children (nonconservers, 5-6 years of age) and school-age children (conservers, 9-10 years of age) were presented with Piaget’s conservation-of-number task and monitored by functional magnetic resonance imaging (fMRI). The cognitive change allowing children to access conservation was shown to be related to the neural contribution of a bilateral parietofrontal network involved in numerical and executive functions. These fMRI results highlight how the behavioral and cognitive stages Piaget formulated during the 20th century manifest in the brain with age. 相似文献

In the present research, we examined why some people have more difficulty than others in staying faithful to their romantic partners. Three studies supported our main prediction that executive control is associated with romantically involved individuals' ability to stay faithful. Study 1 showed that participants with a higher level of executive control reported less difficulty in staying faithful to their partners than did those with lower levels of executive control. In Study 2, romantically involved male participants were placed in a waiting room together with an attractive female confederate. Results showed that participants with a higher level of executive control showed less flirting behavior with the confederate than did those with lower levels of executive control. Study 3 demonstrated that a higher level of executive control was related to a lower expressed desire to meet an attractive other, but only for romantically involved participants. Together, these studies showed that executive control helps romantically involved individuals to deal with the lure of attractive alternatives. 相似文献

Does mimicking affect the way you think about yourself in relation to other people? In the present study, we instructed participants to either mimic or not mimic the expressions of their interaction partner. After a 3-minute interaction, participants' self-view in relation to others was measured. Results revealed that mimickers defined themselves more in relation to others than nonmimickers. Thus, mimicking others, compared to not mimicking others, changes your self-view. 相似文献
