Causal Networks or Causal Islands? The Representation of Mechanisms and the Transitivity of Causal Judgment 下载免费PDF全文
Knowledge of mechanisms is critical for causal reasoning. We contrasted two possible organizations of causal knowledge—an interconnected causal network, where events are causally connected without any boundaries delineating discrete mechanisms; or a set of disparate mechanisms—causal islands—such that events in different mechanisms are not thought to be related even when they belong to the same causal chain. To distinguish these possibilities, we tested whether people make transitive judgments about causal chains by inferring, given A causes B and B causes C, that A causes C. Specifically, causal chains schematized as one chunk or mechanism in semantic memory (e.g., exercising, becoming thirsty, drinking water) led to transitive causal judgments. On the other hand, chains schematized as multiple chunks (e.g., having sex, becoming pregnant, becoming nauseous) led to intransitive judgments despite strong intermediate links ((Experiments 1–3). Normative accounts of causal intransitivity could not explain these intransitive judgments (Experiments 4 and 5). 相似文献

Bible Beliefs,Conservative Religious Identity,and Same‐Sex Marriage Support: Examining Main and Moderating Effects 下载免费PDF全文
Samuel L. Perry 《Journal for the scientific study of religion》2015,54(4):792-813
Research finds that Americans who espouse theologically conservative beliefs about the Bible generally oppose same‐sex marriage. Studies exploring this link, however, have been limited in that their operationalization of fundamentalist belief has been problematically conceptualized and they have potentially confounded the effect of conservative religious identity. The current study asks: (1) How do distinct beliefs about the nature and authority of the Bible influence same‐sex marriage support? (2) Do these beliefs influence same‐sex marriage support independently of conservative religious identity? (3) To what extent do Bible beliefs and conservative religious identity moderate one another's effects? And (4) to what extent are these factors moderated by religious tradition and frequency of Bible reading? Analyses of 2006 Portraits of American Life Study data reveal that while identifying as religiously conservative is the strongest predictor of opposition to same‐sex marriage, believing in inerrancy and creationism remain strong predictors in full models. I also find moderating effects between belief in creationism, inerrancy, inspiration; religious‐conservative identity; and religious tradition. Findings clarify how theological beliefs and religious identity shape support for same‐sex marriage across religious traditions. 相似文献

Clinical utility, or the usefulness of a diagnostic system in clinical practice, has been identified as an important construct in proposed revisions to the diagnostic nomenclature and a significant limitation of dimensional models of personality disorder, such as the 5-factor model (FFM). Only 1 study to date has addressed explicitly the clinical utility of the FFM, and the findings suggested significant limitations. In the current study, 245 practicing psychologists described 3 historic cases using both the FFM and the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 2000) and then rated each model on 6 aspects of clinical utility. In contrast to prior research, the psychologists in this study considered the FFM to have greater clinical utility than the existing diagnostic categories. 相似文献

In this article, the authors demonstrate a laboratory analogue of medical diagnostic biasing (V. R. LeBlanc, G. R. Norman, & L. R. Brooks, 2001) in 2 experiments and explore the basis of this effect. Before categorizing novel exemplars, participants first evaluated the likelihood that the item was a member of the category suggested on that trial: either the correct category or a plausible alternative category. This was sufficient to produce a substantial bias toward the suggested category despite the use of unambiguous stimuli, explicit rules, and unhurried conditions--each of which would be likely to limit diagnostic bias. The authors argue that the production of this effect requires distinguishing between particular feature instantiations and more abstract representations of those features as well as allowing people to adopt a particular decision strategy mediating the use of instantiated features: a feature-recognition heuristic. 相似文献

In each of two experiments, the comparative instructions in a symbolic comparison task were either varied randomly from trial to trial (mixed blocks) or left constant (pure blocks) within blocks of trials. In the first experiment, every stimulus was compared with every other stimulus. The symbolic distance effect (DE) was enhanced, and the semantic congruity effect (SCE) was significantly larger, when the instructions were randomized than when they were blocked. In a second experiment, each stimulus was paired with only one other stimulus. The SCE was again larger when instructions were randomized than when they were blocked. The enhanced SCE and DE with randomized instructions follow naturally from evidence accrual views of comparative judgments. 相似文献
