Effects of Damage to Right-Hemisphere Brain Structures on Spontaneous Emotional and Social Judgments
Andrea S. Heberlein Ralph Adolphs James W. Pennebaker Daniel Tranel 《Political psychology》2003,24(4):705-726
Recent work in cognitive and social neuroscience has focused on the neural substrates of social judgment. The present study explores the effects of damage to the right-hemisphere somatosensory cortices (RSS), a region known for its role in emotion recognition. Seven subjects with RSS damage were shown a short movie depicting objects that move in socially suggestive ways, a stimulus that typically elicits spontaneous social and emotional attributions from normal subjects. The spontaneous verbal responses of RSS-damaged subjects to this movie were compared to those of normal subjects as well as brain-damaged control subjects; the data were derived using a word count and categorization computer program. This method measures spontaneous social and emotional judgments rather than the more typical rating and labeling measures used in neuropsychological studies of social judgment. As predicted, relative to brain-damaged and normal controls, subjects with RSS damage reacted to the stimulus movie with fewer words in categories describing emotional and social processes, despite using a similar total number of words (and slightly more words describing movement, a control category). These results provide further evidence for the role of the RSS in social/emotional processing and identify a role for the RSS in automatic representation in ourselves of body states of others to foster emotion recognition and social cognition. 相似文献

We investigate a contractionless naive set theory, due to Grisin [11]. We prove that the theory is undecidable. 相似文献

In recent years a number of articles have focused on the identifiability of the basic local independence model. The identifiability issue usually concerns two model parameter sets predicting an identical probability distribution on the response patterns. Both parameter sets are applied to the same knowledge structure. However, nothing is known about cases where different knowledge structures predict the same probability distribution. This situation is referred to as ʻempirical indistinguishabilityʼ between two structures and is the main subject of the present paper. Empirical indistinguishability is a stronger form of unidentifiability, which involves not only the parameters, but also the structural and combinatorial properties of the model. In particular, as far as knowledge structures are concerned, a consequence of empirical indistinguishability is that the existence of certain knowledge states cannot be empirically established. Most importantly, it is shown that model identifiability cannot guarantee that a certain knowledge structure is empirically distinguishable from others. The theoretical findings are exemplified in a number of different empirical scenarios. 相似文献

The prevalence and persistence of thoughts of death and suicide during early adolescence were estimated in a community‐based cohort. A latent class approach was used to identify distinct subgroups based on endorsements to depression items administered repeatedly over 24 months. Two classes emerged, with 75% in a low ideation class across four assessments. Less than 2% persisted in the high ideation class over three or more assessments. African American and Asian American adolescents were more likely than European Americans to belong to the high ideation class. No members of the low ideation class endorsed “thought about killing myself,” while “thoughts of death and dying” was endorsed by members of both classes. Implications for interpreting meanings of death and suicide ideation in early adolescence are discussed. 相似文献

Simone Weil's writings suggest that human compassion is divinely revelatory to the extent that interpersonal union and estrangement intensify identically and simultaneously. The relational space of compassionate communion is aporetic; the more attuned one becomes to an afflicted other, the more unreachable this other is seen to be. In her uniquely poetic style of writing, Weil locates perhaps the most intense experience of God directly in the center of this aporia. Compassion between two people—a sufferer and an empathizer—becomes a locus of divine manifestation as it instantiates the (im)possible distance and oneness of Creation, Incarnation, and Cross. 相似文献

Avian brood parasites depend on other species, the hosts, to raise their offspring. During the breeding season, parasitic
cowbirds (Molothrus sp.) search for potential host nests to which they return for laying a few days after first locating them. Parasitic cowbirds
have a larger hippocampus/telencephalon volume than non-parasitic species; this volume is larger in the sex involved in nest
searching (females) and it is also larger in the breeding than in the non-breeding season. In nature, female shiny cowbirds Molothrus bonariensis search for nests without the male’s assistance. Here we test whether, in association with these neuroanatomical and behavioural
differences, shiny cowbirds display sexual differences in a memory task in the laboratory. We used a task consisting of finding
food whose location was indicated either by the appearance or the location of a covering disk. Females learnt to retrieve
food faster than males when food was associated with appearance cues, but we found no sexual differences when food was associated
with a specific location. Our results are consistent with the view that parasitism and its neuroanatomical correlates affect
performance in memory tasks, but the effects we found were not in the expected direction, emphasising that the nature of avian
hippocampal function and its sexual differences are not yet understood.
