Previous studies have shown inconsistent findings regarding the contribution of the different prefrontal regions in emotion recognition. Moreover, the hemispheric lateralization hypothesis posits that the right hemisphere is dominant for processing all emotions regardless of affective valence, whereas the valence specificity hypothesis posits that the left hemisphere is specialized for processing positive emotions while the right hemisphere is specialized for negative emotions. However, recent findings suggest that the evidence for such lateralization has been less consistent. In this study, we investigated emotion recognition of fear, surprise, happiness, sadness, disgust, and anger in 30 patients with focal prefrontal cortex lesions and 30 control subjects. We also examined the impact of lesion laterality on recognition of the six basic emotions. The results showed that compared to control subjects, the frontal subgroups were impaired in recognition of three negative basic emotions of fear, sadness, and anger – regardless of the lesion laterality. Therefore, our findings did not establish that each hemisphere is specialized for processing specific emotions. Moreover, the voxel-based lesion symptom mapping analysis showed that recognition of fear, sadness, and anger draws on a partially common bilaterally distributed prefrontal network. 相似文献

This study examined pinyin (the official phonetic system that transcribes the lexical tones and pronunciation of Chinese characters) invented spelling and English invented spelling in 72 Mandarin-speaking 6th graders who learned English as their second language. The pinyin invented spelling task measured segmental-level awareness including syllable and phoneme awareness, and suprasegmental-level awareness including lexical tones and tone sandhi in Chinese Mandarin. The English invented spelling task manipulated segmental-level awareness including syllable awareness and phoneme awareness, and suprasegmental-level awareness including word stress. This pinyin task outperformed a traditional phonological awareness task that only measured segmental-level awareness and may have optimal utility to measure unique phonological and linguistic features in Chinese reading. The pinyin invented spelling uniquely explained variance in Chinese conventional spelling and word reading in both languages. The English invented spelling uniquely explained variance in conventional spelling and word reading in both languages. Our findings appear to support the role of phonological activation in Chinese reading. Our experimental linguistic manipulations altered the phonological awareness item difficulties. 相似文献

Identifying methods that enable prediction of psychopathology that results from military service is crucial for individual and mission readiness, and for postdeployment mental health. In the present study, we investigate the relationship between sensation seeking (SS) and posttraumatic stress disorder (PTSD) and between SS and depression. Data from 743 Danish soldiers deployed to Afghanistan in 2009 were collected 6 times: before deployment, during deployment, 1–3 weeks after homecoming, 2 months after homecoming, 7 months after homecoming, and 2.5 years after homecoming. In this study, we did not find a relationship between SS and PTSD, or between SS and depression. The present study does not support previous findings that link SS with psychopathology. The structural environment in the military setting, the extent of exposure and type of stressful situations may play a moderating role. More extreme environments, such as imprisonment and torture, may favor different expressions of SS. Further research should include other factors such as context and the extent and type of traumatic exposure in relation to SS. 相似文献

Perfectionism is hypothesized to contribute to the etiology of anorexia nervosa (AN). However, there is little research regarding whether individuals with AN can be classified according to maladaptive (e.g., evaluative concerns) and adaptive (e.g., high personal standards) facets of perfectionism that predict distinct outcomes and might warrant different intervention approaches. In this study, a latent profile analysis was conducted using data from adults with AN (n?=?118). Frost Multidimensional Perfectionism Scale (Frost et al. Cognitive Therapy and Research, 14(5), 449–46, 1990) subscales were used to identify subgroups differing according to endorsed perfectionism features (e.g., adaptive and maladaptive perfectionism). Generalized linear models were used to compare subgroups on eating disorder and affective symptoms measured through questionnaire and ecological momentary assessment. Four subgroups were identified: (a) Low Perfectionism; (b) High Adaptive and Maladaptive Perfectionism; (c) Moderate Maladaptive Perfectionism; and (d) High Maladaptive Perfectionism. Subgroups differed on overall eating disorder symptoms (p?<?.001), purging (p?=?.005), restrictive eating (p?<?.001), and body checking (p?<?.001) frequency, depressive (p?<?.001) and anxiety (p?<?.001) symptoms, and negative (p?=?.001) and positive (p?<?.001) affect. The Low Perfectionism group displayed the most adaptive scores and the Moderate and High Maladaptive Perfectionism groups demonstrated the most elevated clinical symptoms. The High Adaptive and Maladaptive Perfectionism group demonstrated low affective disturbances, but elevated eating disorder symptoms. Results support the clinical significance of subtyping according to perfectionism dimensions in AN. Research is needed to determine if perfectionism subtyping can enhance individualized treatment targeting in AN. 相似文献

The investigation of the semantic space associated with subjective affective experiences or feelings linked to odour perception has recently emerged. Because of the specificity of the emotional effects of odours, the terms derived from traditional models of emotion are unlikely to optimally account for odour-associated feelings. In this study, sets of terms derived from two traditional models, basic emotions and valence by arousal by dominance dimensional emotions, were compared with a recently elaborated olfaction-specific set of terms (Geneva Emotion and Odour Scale; GEOS). Three main criteria were considered: (1) the feeling's intensity reported in response to odours; (2) the inter-rater agreement concerning the reported feelings; and (3) the power to discriminate feelings evoked by various odorous substances. The evidence strongly suggested that the set of terms proposed by GEOS outperformed the terms derived from the two classical models in measuring the subjective affective experience elicited by odours. These results are interpreted with respect to a good correspondence between the functions of olfaction and the meaning conveyed by GEOS terms. 相似文献

Remodeling of the neuronal circuits underlying opiate-withdrawal memories following remote retrieval
Several types of memory display time-dependent reorganization of their underlying neural substrates, but it remains unclear whether affective memories associated with drug effects also follow similar reorganization. Here, we analyzed the neural circuits reactivated by the re-exposure of former dependent rats to the withdrawal-paired environment 1month after conditioning (remote memory) as compared with recent memory (Frenois, F., Stinus, L., Di Blasi, F., Cador, M., & Le Moine, C. (2005) A specific limbic circuit underlies opiate withdrawal memories The Journal of Neuroscience, 25, 1366-1374). C-fos expression showed that the circuits involved in the retrieval of withdrawal memories are partly different when comparing recent and remote reactivation, showing that, like other type of memories, affective memories linked to opiate withdrawal undergo anatomical reorganization, with a shift from extended amygdala regions toward cortical areas. 相似文献

An experiment was conducted using a human instrumental learning task with the goal of evaluating the mechanisms underlying the deleterious effect of context-switching on responding to an unambiguous stimulus when contexts are informative to solve the task. Participants were trained in a context-based reversal discrimination in which two discriminative stimuli (X and Y) interchange their meaning across contexts A and B. In context A, discriminative stimulus Z consistently announced that the relationship between a specific instrumental response (RI) and a specific outcome (O1) was in effect. Performance in the presence of stimulus Z was equally deteriorated when the test was conducted outside the training context, regardless of whether the test context was familiar (context B) or new (context C). This result is consistent with the idea that participants code all the information presented in an informative context as context-specific with the context playing a role akin to an occasion setter. 相似文献

The purpose of this paper is to identify groups of cardiac patients who share similar perceptions about their illness and to examine the relationships between these schemata and psychosocial outcomes such as quality of life and depression. A total of 190 cardiac patients with diagnoses of myocardial infarction, stable angina pectoris or chronic heart failure, completed a battery of psychosocial questionnaires within four weeks of their admission to hospital. These included the Brief Illness Perceptions Questionnaire (BIPQ), Beck Depression Inventory II (BDI II) and The MacNew Health-related Quality of Life instrument (MacNew). BIPQ items were subjected to latent class analysis (LCA) and the resulting groups were compared according to their BDI II and MacNew scores. LCA identified a five-class model of illness perception which comprised the following: (1) Consequence focused and mild emotional impact, n?=?55, 29%; (2) Low illness perceptions and low emotional impact, n?=?45, 24%; (3) Control focused and mild emotional impact, n?=?10, 5%; (4) Consequence focused and high emotional impact, n?=?60, 32%; and (5) Consequence focused and severe emotional impact, n?=?20, 10%. Gender and diagnosis did not appear to reflect class membership except that class 2 had a significantly higher proportion of AMI patients than did class 5. There were numerous significant differences between classes in regards to depression and health-related quality of life. Notably, classes 4 and 5 are distinguished by relatively high BDI II scores and low MacNew scores. Identifying classes of cardiac patients based on their illness perception schemata, in hospital or shortly afterwards, may identify those at risk of developing depressive symptoms and poor quality of life. 相似文献
