Metric and nonmetric plotting models

A problem with standard printer scatterplot routines is that points are not adequately labeled. Four methods of generating printer plots are presented. All four methods allow multi-character point labels, and three of the methods can guarantee that no portion of the labels are hidden. This is accomplished by using varying amounts of metric and nonmetric distance information to locate the points.The author wishes to thank Warren Sarle and Forrest Young who provided many valuable suggestions during the development of PROC IDPLOT.The methods and procedure described in this paper were developed by the author at the University of North Carolina as a part of a software development project funded by SAS Institute Inc.     

A normative set of 98 pairs of nonsensical pictures (droodles)

Our purpose in the present study is to provide a normative set of nonsensical pictures known as droodles and to demonstrate the role of semantic comprehension in facilitating recall of pictorial stimuli. The set consists of 98 pairs of droodles. Experiment 1 standardized these pictorial stimuli with respect to several variables, such as appropriateness of verbal labels, relationship between two droodles, and correct recall. Appropriateness of verbal labels was rated higher for pictures presented in pairs than for pictures presented singly. Experiment 2 used the standardized set of droodles in a recall experiment similar to those of Bower, Karlin, and Dueck (1975) and others. As we expected, semantic interpretation can strongly facilitate recall. Multiple regression analysis showed that several measures had significant power of explanation for recall performance.

Effects of Social Deviance Labels on Judgements of Facial Attractiveness: A Comparison of Labelling Procedures Using Japanese Raters

Are people labelled as social deviants also perceived as less physically attractive? Four studies conducted in Japan examined judgements of male social-deviants' attractiveness using several labelling procedures. Study 1 determined attractiveness judgement and social distance of various social groups, and Study 2 examined the effect of three labels on attractiveness judgement of 16 portraits. In Studies 3 and 4 subjects were asked to match 8 or an unlimited number of the 16 portraits with the same 3 labels. Findings indicate that labelling a person negatively resulted in a decrease in attractiveness ratings. Overall, however, the labelling pattern was found to affect attractiveness judgement. Finally, this study provides cross-cultural support for the stereotypical association between social deviants and low attractiveness.     

Investigation of Ethnic Self‐Labeling in the Latina Population: Implications for Counselors and Counselor Educators

Using a qualitative approach, the author explored the process of ethnic label selection, change, and the meaning assigned to ethnic labels. Ten women of Mexican descent participated in semistructured, in‐depth interviews. Phenomenological analysis of the data revealed several themes, including the importance of family, ancestral traditions, and cultural traits; label as identity; and labels as complex and dynamic. Factors that influenced label choice, meaning, and change; implications for counselors and counselor educators; and limitations and suggestions for future research were addressed.     

The role of legal stigmatization in the enhancement of treatment goals for problem drinkers

Traditionally, labeling theory has neglected the active capacity of labeled individuals: the capacity to respond in several different ways to a stigmatizing label. Several writers have dealt with this issue, yet there is little data dealing with alternative responses to a stigmatizing label. This research tests the hypothesis that stigmatizing labels (in the form of legal intervention) can result in conventionalizing the problem drinker's behavior, and further tests two conditions deemed necessary before the hypothesis will be valid. The overall proposition—that stigmatizing labels can result in conventionalizing behavior—was supported by this research. The first condition—that the change agent responsible for the promotion of behavior change must be an ex‐practitioner of the relevant deviance and an identifiable role model for the client—was also supported. Finally, the second condition—that membership in the behavior‐changing group must be voluntary—was invalidated.     

Information sources for noun learning

Why are some words easier to learn than others? And what enables the eventual learning of the more difficult words? These questions were addressed for nouns using a paradigm in which adults were exposed to naturalistic maternal input that was manipulated to simulate access to several different information sources, both alone and in combination: observation of the extralinguistic contexts in which the target word was used, the words that co‐occurred with the target word, and the target word's syntactic context. Words that were not accurately identified from observation alone were both abstract (e.g., music) and concrete (e.g., tail). Whether a noun could be learned from observation depended on whether it labeled a basic‐level object category (BLOC). However, the difference between BLOC labels and non‐BLOC labels was eliminated when observation was supplemented with linguistic context. Thus, although BLOC labels can be learned from observation alone, non‐BLOC labels require richer linguistic context. These findings support a model of vocabulary growth in which an important role is played by changes in the information to which learners have access.     

特征相似性、类别标签与因果关系在归纳推理中的作用

采用人工材料,比较类别标签、特征相似性与因果关系对归纳推理强度的影响。包括两个实验,实验1比较类别标签与特征相似性对归纳推理的影响,结果表明,当类别标签对归纳推理的影响显著强于特征相似性时,不能将类别标签等同于一个相似性特征。实验2进一步探讨类别标签与因果关系对归纳推理的作用,结果表明,因果关系作用明显强于类别标签的作用。综合两个实验的结果并整合前人相关研究,提出了不同关系影响归纳推理的强度假想。     

Novel Labels Increase Category Coherence,But Only When People Have the Goal to Coordinate

From infancy, we recognize that labels denote category membership and help us to identify the critical features that objects within a category share. Labels not only reflect how we categorize, but also allow us to communicate and share categories with others. Given the special status of labels as markers of category membership, do novel labels (i.e., non‐words) affect the way in which adults select dimensions for categorization in unsupervised settings? Additionally, is the purpose of this effect primarily coordinative (i.e., do labels promote shared understanding of how we categorize objects)? To address this, we conducted two experiments in which participants individually categorized images of mountains with or without novel labels, and with or without a goal of coordination, within a non‐communicative paradigm. People who sorted items with novel labels had more similar categories than people who sorted without labels only when they were told that their categories should make sense to other people, and not otherwise. We argue that sorters' goals determine whether novel labels promote the development of socially coherent categories.     

Category and feature identification

This paper considers a family of inductive problems where reasoners must identify familiar categories or features on the basis of limited information. Problems of this kind are encountered, for example, when word learners acquire novel labels for pre-existing concepts. We develop a probabilistic model of identification and evaluate it in three experiments. Our first two experiments explore problems where a single category or feature must be identified, and our third experiment explores cases where participants must combine several pieces of information in order to simultaneously identify a category and a feature. Humans readily solve all of these problems, and we show that our model accounts for human inferences better than several alternative approaches.     

Tracking mouse movement in feature inference: Category labels are different from feature labels

In this article, we examine the role of category labels in inductive inference. Some leading research has suggested that information about category membership works just like any other feature in categorical inductions, whereas other research has proposed that the influence of category membership on induction goes beyond that of other features. To investigate these claims further, we developed an online measure of judgments that is akin to eyetracking. The judgment results and the mouse-tracking data jointly support the view that category labels do affect inductive inferences in a way distinct from that for feature information. When arbitrary labels conveyed category membership information, participants viewed these labels more often and earlier in a trial, in comparison with cases in which the same labels conveyed non-membership information. Our results suggest that category membership information works like a guide for inference. An ecological rationale for this induction strategy is also discussed.     

The lasting effect of words on feelings: words may facilitate exposure effects to threatening images

Previous studies have shown that mere words, particularly affective words, can dampen emotional responses. However, the effect of affective labels on emotional responding in the long term is unknown. The authors examined whether repeated exposure to aversive images would lead to more reduction in autonomic reactivity a week later if the images were exposed with single-word labels than without labels. In Experiment 1, healthy individuals were exposed to pictures of disturbing scenes with or without labels on Day 1. On Day 8, the same pictures from the previous week were exposed, this time without labels. In Experiment 2, participants were spider fearful and were exposed to pictures of spiders. In both experiments, although repeated exposure to aversive images (without labels) led to long-term attenuation of autonomic reactivity, exposure plus affective labels, but not nonaffective labels, led to more attenuation than exposure alone. Thus, affective labels may help dampen emotional reactivity in both the short and long terms. Implications for exposure therapy and translational studies are discussed.     

The link between statistical segmentation and word learning in adults

Many studies have shown that listeners can segment words from running speech based on conditional probabilities of syllable transitions, suggesting that this statistical learning could be a foundational component of language learning. However, few studies have shown a direct link between statistical segmentation and word learning. We examined this possible link in adults by following a statistical segmentation exposure phase with an artificial lexicon learning phase. Participants were able to learn all novel object-label pairings, but pairings were learned faster when labels contained high probability (word-like) or non-occurring syllable transitions from the statistical segmentation phase than when they contained low probability (boundary-straddling) syllable transitions. This suggests that, for adults, labels inconsistent with expectations based on statistical learning are harder to learn than consistent or neutral labels. In contrast, a previous study found that infants learn consistent labels, but not inconsistent or neutral labels.     

Naming practices,typicality, and underextension in child language

Preschool children (3 to 5 years of age) in an initial study underextended superordinate labels. The labels (e.g., food) were not applied to category instances that were rated as atypical by adults (e.g., ketchup). In a second experiment, mothers seldom used a superordinate term in referring to pairs of the same atypical instances, but they did label pairs of typical instances with a superordinate. A third experiment demonstrated the effects of several word-referent modeling conditions on young children's comprehension of a superordinate term. The results were viewed as suggesting that the child undergeneralizes superordinate labels because adult naming practices are such that category instances having certain functional or perceptual attributes may be labeled with a superordinate, while other, dissimilar instances are almost always labeled with subordinate names instead of a superordinate.     

Labels can override perceptual categories in early infancy

An extensive body of research claims that labels facilitate categorisation, highlight the commonalities between objects and act as invitations to form categories for young infants before their first birthday. While this may indeed be a reasonable claim, we argue that it is not justified by the experiments described in the research. We report on a series of experiments that demonstrate that labels can play a causal role in category formation during infancy. Ten-month-old infants were taught to group computer-displayed, novel cartoon drawings into two categories under tightly controlled experimental conditions. Infants were given the opportunity to learn the two categories under four conditions: Without any labels, with two labels that correlated with category membership, with two labels assigned randomly to objects, and with one label assigned to all objects. Category formation was assessed identically in all conditions using a novelty preference procedure conducted in the absence of any labels. The labelling condition had a decisive impact on the way infants formed categories: When two labels correlated with the visual category information, infants learned two categories, just as if there had been no labels presented. However, uncorrelated labels completely disrupted the formation of any categories. Finally, consistent use of a single label across objects led infants to learn one broad category that included all the objects. These findings demonstrate that even before infants start to produce their first words, the labels they hear can override the manner in which they categorise objects.     

Labeling effects on memory for nonsense pictures

It has been shown that labeling nonsense pictures improves memory for them, but how the label takes effect is uncertain. In this study subjects viewed nonsense pictures with or without labels; in the former case, the labels were either meaningful or nonmeaningful with respect to the pictures. Then the subjects took part in a free recall test, followed by recall in the presence of cues. Only the meaningful labels facilitated free recall of the pictures, but both types of labels facilitated cued recall. The results suggest that a meaningful label affects picture encoding by providing a conceptual interpretation for the picture; a nonmeaningful label, in contrast, appears to provide only an ad hoc associative cue.     

Mandatory Cancer Risk Warnings on Alcoholic Beverages: What Are the Ethical Issues?

The link between alcohol consumption and cancer is well established, but public awareness of the risk remains low. Mandated warning labels have been suggested as a way of ensuring “informed choice” about alcohol consumption. In this article we explore various ethical issues that may arise in connection with cancer warning labels on alcoholic beverages; in particular we highlight the potentially questionable autonomy of alcohol consumption decisions (either with or without labels) and consider the implications if the autonomy of drinking behavior is substantially compromised. Our discussion demonstrates the need for the various ethical issues to be considered and addressed in any decision to mandate cancer warning labels.     

智者必怀仁？智慧与美德的关系辨析

智慧与美德是独立但相互作用的心理结构。针对其关系,以往哲学家与心理学家基于个人经验和文化观念进行了大量规范性层面的理论思辨,但仍存在理论分歧（线性论、阈值论、从属论）,且缺少以定量方法为主的描述性层面的实证研究,尤其缺乏基于实验的关于“智”与“仁”双向因果关系的探索。未来研究可以借鉴实验伦理学的范式,着眼于研究特定领域、特定情境下智慧与美德之间的双向因果关系,加强中国文化背景下的智慧与美德关系的研究,并探索其潜在的认知神经机制。如何统一智慧与美德关系的“应然”与“实然”的研究,是接下来需要面临的挑战。     

The role of redundant verbal labels in 8- and 10-month-olds’ working memory

Verbal labels have been shown to help preverbal infants’ performance on various cognitive tasks, such as categorization. Redundant labels also aid adults’ visual working memory (WM), but it is not known if this linguistic benefit extends to preverbal infants’ WM. In two eye-tracking studies, we tested whether 8- and 10-month-old infants’ WM performance would improve with the presence of redundant labels in a Delayed Match Retrieval (DMR) paradigm that tested infants’ WM for object-location bindings. Findings demonstrated that infants at both ages were unable to remember two object-location bindings when co-presented with labels at encoding. Moreover, infants who encoded the object-location bindings with labels were not significantly better than those who did so in silence. These findings are discussed in the context of label advantages in cognition and auditory dominance.     

儿童归纳推理中的标签作用

传统的归纳推理观主要包括特征相似性观和概念观。在基于这两种传统观点的研究过程中,研究者逐渐发现类别知识,特别是标签起到的独特作用,但目前关于不同类型标签作用的分析还缺乏系统性。该文从分析目前两大主要标签研究现状——语言标签和类别标签入手,试图明确标签作用和关系、解释混淆和误解;同时,作者就以标签为载体的研究同儿童语言发展间存在的密切联系提出了儿童归纳推理发展的语言认知模式。文章最后认为未来的研究方向应集中在对机制、技术和深层次内部关系三方面问题的探讨上。     

Linguistic labels: Conceptual markers or object features?

Linguistic labels affect inductive generalization; however, the mechanism underlying these effects remains unclear. According to one similarity-based model, SINC (similarity, induction, naming, and categorization), early in development labels are features of objects contributing to the overall similarity of compared entities, with early induction being similarity based. If this is the case, then not only identical but also phonologically similar labels may contribute to the overall similarity and thus to induction. These predictions were tested in a series of experiments with 5-year-olds and adults. In Experiments 1-5 participants performed a label extension task, whereas in Experiment 6 they performed a feature induction task. Results indicate that phonological similarity contributes to early induction and support the notion that for young children labels are features of objects.
