Acquired capability for suicide is associated with increased suicide risk and behaviors, but little research has examined factors that may qualify this relationship. Body investment is proposed as one such factor, as it may engage self-preservation instincts and serve as a buffer to capability for suicide. It was expected that facets of body investment (body feelings, body care, comfort with touch, and body protection) would moderate the relationship between acquired capability for suicide and suicide attempts. The current study included a sample of 1,150 undergraduate students with a mean age of 19.74 (3.44). The majority of the sample identified as female (71%) and White/Caucasian (78%). Participants completed self-report measures of body investment (Body Investment Scale [BIS]), acquired capability (Acquired Capability for Suicide Scale [ACSS]), suicide thoughts and attempt history (Self-Harm Behavior Questionnaire [SHBQ]), and demographic information. Four moderation analyses were run using the PROCESS macro; one for each body investment subscale. All facets of body investment showed significant moderation except for body care. Acquired capability was significantly associated with suicide attempts when body feelings, comfort with touch, and body protection were low, but not when they were high. Results indicate that fostering aspects of body investment may be important for suicide prevention. 相似文献

The relationship between firearm ownership and suicide is well documented. This study hypothesized that how soldiers store their firearms would moderate the relationship between suicidal ideation and the self-reported likelihood of engaging in a future suicide attempt, and that this relationship would be explained by fearlessness about death. There were 432 military personnel (91.3% men, 74.2% White, Mage = 27.60) who endorsed current ownership of a private firearm and who were recruited from a military base in the southeastern United States (94.5% National Guard). Firearm storage moderated the relationship between suicidal ideation and the self-reported likelihood of engaging in a future suicide attempt, but this relationship was not explained by fearlessness about death. Individuals who reported keeping their firearms loaded and stored in an unsecure location exhibited higher mean levels of fearlessness about death. Findings highlight the need for research examining contributors to suicide risk in the context of firearm storage, and provide support for suicide prevention efforts involving restricting means. 相似文献

Whether Jung was a Lamarckian or not has always been a hotly debated topic, both within the post‐Jungian community and amongst scholars with an interest in Jung in the wider academic community. Yet surprisingly few substantial pieces of work have been dedicated to it and, to my mind, no one has yet managed to do justice to all the subtleties involved. The scholars who have claimed that Jung is a Lamarckian have, for the most part, oversimplified the debate by failing to discuss the passages in which Jung appears to be defending himself against Lamarckism; the scholars who have defended Jung against Lamarckism, however, have as a rule not adequately dealt with the question of whether these passages actually get Jung off the hook. This paper will attempt to correct this imbalance by putting forward four key passages spanning Jung's career that all represent conclusive evidence that Jung was indeed a Lamarckian. After discussing these, it will then deal in detail with the passages in which Jung appears to be defending himself against Lamarckism, making the case that they do not represent a defence against Lamarckism at all and have therefore generally been misinterpreted by many scholars. 相似文献

Despite the apparent sociability of human kind, immoral behaviour is ever present in society. The term ‘immoral behaviour’ represents a complex array of conduct, ranging from insensitivity to topics of conversation through to violent assault and murder. To better understand the neuroscience of immoral behaviour, this review investigates two clinical populations that commonly present with changes in moral behaviour – behavioural-variant frontotemporal dementia and acquired brain injuries. Based on evidence from these groups, it is argued that rather than a single underlying cause, immoral behaviour can result from three distinct types of cognitive failure: (1) problems understanding others; (2) difficulties controlling behaviour; or (3) deficits in the capacity to make appropriate emotional contributions. Each of these failures is associated with damage to different brain regions. A more nuanced approach to the neuroscience of immoral behaviour has important implications for our understanding of immoral behaviour in a wide range of clinical groups, as well as human society more broadly. 相似文献

Acquired equivalence is a paradigm in which generalization is increased between two superficially dissimilar stimuli (or antecedents) that have previously been associated with similar outcomes (or consequents). Several possible mechanisms have been proposed, including changes in stimulus representations, either in the form of added associations or a change of feature salience. A different way of conceptualizing acquired equivalence is in terms of strategic inference: Confronted with a choice on which it has no evidence, the organism may infer from its history of reinforcement what the best option is, and that inference is observed as acquired equivalence. To test this account, we combined an incremental learning task with an episodic memory test. Drawings of faces were made equivalent through acquired equivalence training, and then paired with words in a list learning paradigm. When participants were asked to recognize specific face-word pairings, they confused faces more often when they had been made equivalent. This suggests that prior acquired equivalence training does influence how memories are coded. We also tested whether this change in coding reflected acquisition of new associations, as suggested by the associative mediation account, or whether stimuli become more similar through a reweighting of stimulus features, as assumed by some categorization theories. Results supported the associative mediation view. We discuss similarities between this view and exemplar theories of categorization performance. 相似文献

Biological self reference idioms in brain-centered or nervous-system-centered self determination of the consious Self reveal
an interesting contrast with biological self-determination by immunological self/non-self discrimination. This contrast is
both biological and epistemological. In contrast to the consciousness conscious of itself, the immunological self-determination
imposes a protective mechanism against self-recognition (Coutinho et al. 1984), which adds to a largely unconscious achievement
of the biological Self (Popper 1977; Medawar 1959). The latter viewpoint is in contrast with the immunological Self-determination
as an essentially cognitive process as expressed in the analysis of Tauber (1994). Comparison of the immune system in vertebrates
and invertebrates, according to new biological insights, has contributed to a better understanding of the relative role of
innate (or inherited) immunity versus immunity acquired during each individual life. Also in this respect, immunological self-achievement
shows both a striking analogy and a fundamental discrepancy with the activity of the nervous system.
The analysis of immunological Self/non-self discrimination versus brain-centered self-determination adds to the understanding
of the function paradigm in biological self-reference idioms, especially when regarding the importance of the connectivity
notion in both systems. Adopting functional explanatory schemes for understanding immunological self-non-self discrimination,
as well as for the understanding of functional mapping of the brain at (conscious) activity (Friston et al. 1993; Frith et
al. 1995), forwards the notion of effective/functional connectivity. Network connectivity not only is a primary question in
solving the dimensionality question for immunological ‘idiotypic networks’ (Jerne 1974a, b; 1984), it may also have an important
value in describing phase transitions in the development of both immune and nervous systems.

The problem of disease definition is related to theproblem of proving that a certain agent is thenecessary cause of a certain disease. Natural kindterms like rheumatoid arthritis and AIDS refer toessences which are discoverable rather thanpredeterminate. No statement about such diseases isa priori necessarily true. Because theories onnecessary causes involve natural kind semantics,Koch's postulates cannot be used to falsify or verifysuch theories. Instead of proving that agent A is thenecessary cause of disease D, we include A in atheoretical definition of D, take this to representthe real meaning of D, and discard thepretheoretical definition. This is illustrated byKoch's own attempt to prove he had discovered thenecessary cause of tuberculosis. Methodologicalarguments about disease causation require a clear viewof our use of diagnostic terms. Medical lexicographersshould do more to provide such a view. 相似文献

Pigeons were trained on many-to-one matching in which pairs of samples, each consisting of a visual stimulus and a distinctive pattern of center-key responding, occasioned the same reinforced comparison choice. Acquired equivalence between the visual and response samples then was evaluated by reinforcing new comparison choices to one set of samples, and examining generalization of these choices to the other samples. Three separate experiments found no evidence of such generalization, as indexed by performance on class-consistent versus class-inconsistent tests. Other tests showed that the pigeons' center-key response patterns during training had indeed served as a conditional cue for choice. These results do not support the hypothesis that different defined responses can become members of acquired equivalence classes. 相似文献

We report a longitudinal study of an exceptional child (S.R.) whose early-acquired visual agnosia, following encephalitis at 8 weeks of age, did not prevent her from learning to construct an increasing vocabulary of visual object forms (drawn from different categories), albeit slowly. S.R. had problems perceiving subtle differences in shape; she was unable to segment local letters within global displays; and she would bring complex scenes close to her eyes: a symptom suggestive of an attempt to reduce visual crowding. Investigations revealed a robust ability to use the gestalt grouping factors of proximity and collinearity to detect fragmented forms in noisy backgrounds, compared with a very weak ability to segment fragmented forms on the basis of contrasts of shape. When contrasts in spatial grouping and shape were pitted against each other, shape made little contribution, consistent with problems in perceiving complex scenes, but when shape contrast was varied, and spatial grouping was held constant, S.R. showed the same hierarchy of difficulty as the controls, although her responses were slowed. This is the first report of a child's visual–perceptual development following very early neurological impairments to the visual cortex. Her ability to learn to perceive visual shape following damage at a rudimentary stage of perceptual development contrasts starkly with the loss of such ability in childhood cases of acquired visual agnosia that follow damage to the established perceptual system. Clearly, there is a critical period during which neurological damage to the highly active, early developing visual–perceptual system does not prevent but only impairs further learning. 相似文献
