Quantity judgments and individuation: evidence that mass nouns count

Three experiments explored the semantics of the mass-count distinction in young children and adults. In Experiments 1 and 2, the quantity judgments of participants provided evidence that some mass nouns refer to individuals, as such. Participants judged one large portion of stuff to be "more" than three tiny portions for substance-mass nouns (e.g. mustard, ketchup), but chose according to number for count nouns (e.g. shoes, candles) and object-mass nouns (e.g. furniture, jewelry). These results suggest that some mass nouns quantify over individuals, and that therefore reference to individuals does not distinguish count nouns from mass nouns. Thus, Experiments 1 and 2 failed to support the hypothesis that there exist one-to-one mappings between mass-count syntax and semantics for either adults or young children. In Experiment 3, it was found that for mass-count flexible terms (e.g. string, stone) participants based quantity judgments on number when the terms were used with count syntax, but on total amount of stuff when used with mass syntax. Apparently, the presence of discrete physical objects in a scene (e.g. stones) is not sufficient to permit quantity judgments based on number. It is proposed that object-mass nouns (e.g. furniture) can be used to refer to individuals due to lexically specified grammatical features that normally occur in count syntax. Also, we suggest that children learning language parse words that refer to individuals as count nouns unless given morpho-syntactic and referential evidence to the contrary, in which case object-mass nouns are acquired.     

The influence of hierarchy on probability judgment

Consider the task of predicting which soccer team will win the next World Cup. The bookmakers may judge Brazil to be the team most likely to win, but also judge it most likely that a European rather than a Latin American team will win. This is an example of a non-aligned hierarchy structure: the most probable event at the subordinate level (Brazil wins) appears to be inconsistent with the most probable event at the superordinate level (a European team wins). In this paper we exploit such structures to investigate how people make predictions based on uncertain hierarchical knowledge. We distinguish between aligned and non-aligned environments, and conjecture that people assume alignment. Participants were exposed to a non-aligned training set in which the most probable superordinate category predicted one outcome, whereas the most probable subordinate category predicted a different outcome. In the test phase participants allowed their initial probability judgments about category membership to shift their final ratings of the probability of the outcome, even though all judgments were made on the basis of the same statistical data. In effect people were primed to focus on the most likely path in an inference tree, and neglect alternative paths. These results highlight the importance of the level at which statistical data are represented, and suggest that when faced with hierarchical inference problems people adopt a simplifying heuristic that assumes alignment.     

Remarks on the identifiability of thurstonian paired comparison models under multiple judgment

It is well-known that the representations of the Thurstonian models for difference judgment data are not unique. It has been shown that equivalence classes can be formed to provide a more meaningful partition of the covariance structures of the Thurstonian ranking models. In this paper, we examine the equivalence relations between Thurstonian covariance structure models for paired comparison data obtained under multiple judgment and discuss their implications on the general identification constraints and methods to check for parameter identifiability in restricted models.The author is indebted to Ulf Böckenholt and Albert Maydeu-Olivares for their significant comments and suggestions which led to considerable improvement in this article.     

The early acquisition of verb meaning in German by normally developing and language impaired children

The research reported here focuses on the early acquisition of event structure in German. Based on longitudinal studies from 5 normally developing (ND) and 6 language-impaired (LI) children, a model of "event structural bootstrapping" is presented that spells out how ND children log into the verb lexicon. They project a target-consistent event tree, depicting the head-of-event of transitions. Young LI children, failing to employ this bootstrapping strategy, resort to radically underspecified event representations. The results from a truth-value judgment experiment with 16 ND and 16 LI children showed that ND children perform correctly on transitional verbs, while LI children perform at chance level on the same tasks. These findings are accounted for by the model of event structural bootstrapping to the extent that LI children lack an explicit representation of the head-of-event.     

Measuring Judgments of Professionals: Using Vignettes in a Social Survey About Patient Confusion

The use of a factorial survey to measure the clinical judgments of professionals is described. This design allows the researcher to partial out the effects of variables on clinical decision making while using probability sampling. Methods frequently used to study judgments are reviewed and a study of nurses' judgments about patients' confusional episodes are used to illustrate the application of the factorial survey. Acute confusion in patients is a common clinical problem for nurses working in medical-surgical units in acute care hospitals. Using the factorial survey to study a real-life problem such as confusion demonstrates how this design can be used to test judgments in complex clinical situations, to aid in concept development, and to identify consensus among professionals.     

学习次数和材料难度对学习判断绝对准确性的影响

本研究采用5（学习次数）×2（材料难度）被试内设计,考察材料难度和学习次数对即刻和延迟学习判断绝对准确性的影响。45名大学生被试参加实验,共收集有效数据37个。结果表明：（1） 即刻条件下,高、低难度词对都出现了练习伴随低估效应;（2） 延迟条件下,高、低难度词对均未出现练习伴随低估效应。对低难度词对的学习判断准确预测了回忆成绩,高难度词对则出现了练习伴随高估效应;（3） 随着学习次数的增加,不同难度词对在即刻条件下的练习伴随低估效应趋于消失,延迟条件下高难度词对的练习伴随高估效应趋于消失。     

坏念头，罪几何？意图信息的强弱变化对大学生道德判断的影响

成人在对他人的行为进行道德判断时,对意图和结果信息的利用存在不稳定的现象。Cushman提出道德判断双加工过程理论,认为当存在重大负性后果时,需要综合考虑意图和结果信息;而当不存在负性后果时,主要关注意图信息。本研究通过句式变化操控意图信息的明显性,分别考察了两组大学生在对道德情景进行判断时意图信息强弱变化所造成的影响,结果发现：（1）对中性行为进行道德判断时,突显负性意图信息后被试会增加道德谴责;（2）对负性行为进行道德判断时,道德谴责程度没有因意图信息明显性的改变而发生显著变化。此研究结果表明,在行为结果为中性时,人们主要利用意图的信息做出道德判断,但此时对负性意图的谴责程度并不稳定,容易受明显性变化的干扰。     

The Axiology of Moral Experience

This paper clarifies the nature of moral experience, examines its evidential role in supporting moral judgments, and argues that moral experiences can be among the things having intrinsic value. Moral experience is compared with aesthetic experience and contrasted with its close relative, non-moral experience combined with moral beliefs. The concluding sections explore the case for the organicity of intrinsic value and the kind of role such value can play in grounding moral obligation.     

The effects of physical contact and decision type on moral decision making: A study of harm to save moral behavior

This study examined the relationship between physical contact and decision type in predicting “harm to save” behavior. Participants were assigned to making either a judgment or a choice involving moral dilemmas. All participants were presented with dilemmas that either required or did not require having physical contact with potential victims. Participants were asked to decide whether to sacrifice fewer people to save more (utilitarian responses) or not to do so and thus more people would die (deontological responses). The study sample included 345 participants who completed a set of self‐report measures. Results indicated an interaction between physical contact and decision type. In the choice condition only, participants reported significantly less utilitarian responses to the dilemmas that required having physical contact with the person to be harmed than to dilemmas that did not require physical contact. This difference was not found in the judgment condition. These results contribute to a greater understanding of the nature and potential malleability of human morality.
