Toddlers benefit from labeling on an executive function search task

Although labeling improves executive function (EF) performance in children older than 3 years, the results from studies with younger children have been equivocal. In the current study, we assessed performance in a computerized multistep multilocation search task with older 2-year-olds. The correct search location was either (a) not marked by a familiar picture or given a distinct label, (b) marked by a familiar picture but not given a distinct label, (c) marked by a familiar picture and labeled by the experimenter, or (d) marked by a familiar picture and labeled by the participant. The results revealed that accuracy improved across conditions such that children made the fewest errors when they generated the label for the hiding location. These findings support the hierarchical competing systems model, which postulates that improved performance can be explained by more powerful representations that guide search behavior.     

Social learning under the labeling effect: Exploring travellers’ behavior in social dilemmas

This paper presents results of a laboratory experiment, in which subjects made choices between public and private transportation when managing Personal Carbon Allowances (PCAs). The objectives of this study were twofold. Firstly, it was aimed at investigating the labeling effect under the social dilemma context. Secondly, it showed insights into the decision-making process when feedback about others’ choices was provided. A combination of the labeling effect and feedback helped individuals change their commuting pattern and increase the number of trips by public transportation under the PCAs regime. Feedback on others’ choices resulted in social learning and incentivized choice of public transportation more frequently in social dilemma situations.     

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.     

The effect of labeling on preschool children's performance in the Dimensional Change Card Sort Task

Previous research suggests that experimenter-induced labeling of test cards improves preschoolers’ performance on the Dimensional Change Card Sort Task (DCCS), a measure of flexible rule use. Three experiments attempted to further clarify how labeling aids performance on the DCCS. Experiment 1 examined the nature of the labeling effect but failed to show any benefit of labeling on children's performance. Experiment 2 failed to replicate the labeling effect reported by [Kirkham, N. Z., Cruess, L. M., & Diamond, A. (2003). Helping children apply their knowledge to their behavior on a dimension-switching task. Developmental Science, 6, 449–467] despite closely matching their procedures. Experiment 3 demonstrated that labeling procedures designed to counteract the suppression of the post-switch sorting dimension also failed to improve performance on the DCCS. We discuss the implications of these findings for identifying factors that positively affect preschoolers’ cognitive flexibility.     

犯罪心理学研究中运用量化方法引起的理论思考

量化与统计分析,是一项重要的研究方法。这一方法在犯罪心理学研究中得到了广泛运用,同时也存在着使用的局限性。犯罪人有很强的心理掩饰性,对包括犯罪人在内的人的心理的测量实际上是一种间接测量,测得的数据是心理学家标定的数据,兼有客观性与主观性。量化研究如果不与科学思维相结合,有可能得出浅薄平庸甚至错误的结论。心理学研究应当以"人性"为基点,多种方法综合运用,实现量化方法与非量化方法的有机结合。     

Children acquire emotion categories gradually

Some accounts imply that basic-level emotion categories are acquired early and quickly, whereas others imply that they are acquired later and more gradually. Our study examined this question for fear, happiness, sadness, and anger in the context of children's categorization of emotional facial expressions. Children (N = 168, 2–5 years) first labeled facial expressions of six emotions and were then shown a box and asked to put all and only, e.g., scared people in it. Before using fear in labeling, children had begun to include ‘fear’ faces and to exclude other (especially positive) faces from the fear box/category; after using fear, children continued to include other (especially negative) faces. The same pattern was observed for happiness, sadness, and anger. Emotion categories begin broad, including all emotions/faces of the same valence, and then gradually narrow over the preschool years.     

Conversion to non-remunerated plasmapheresis donation: Effects of labeling and donation environment

IntroductionPlasmapheresis donors’ recruitment strategies should focus on asking whole-blood donors (WBDs) to convert to plasmapheresis.ObjectiveThis study measured the effect of labeling on the conversion of WBDs to plasmapheresis donation and examined the relationship between the type of blood drive and conversion to plasmapheresis.MethodsTwo blood drives destined towards students were held either on a university campus (mobile blood drive), or in a blood center. At the end of each whole-blood donation, the nurse performed a labeling, reactivated a few minutes later by a second individual asking the donor if he would agree to donate plasma. If so, an appointment for plasma donation was made or a promise was collected. The number of commitments to plasmapheresis (promise/appointment) and the number of achievements of these commitments measured the effect of labeling.ResultsFew significant differences between social or functional labeling were found compared to a “no labeling” condition in terms of commitments and concretizations. The in-center blood drive achieved three times more engagements than the mobile blood drive (p < .001). Appointments had better chances to turn into a plasma donation than promises (p < .001).ConclusionLabeling as it was tested seemed ineffective in conversion from whole blood donation to plasmapheresis, but further studies should be carried out to replicate these results. When only collected during in-center blood drives, blood collection agencies should try to develop in-center whole blood donations and promotional approaches towards plasma donation. When approaching potential plasmapheresis donors, appointments should be preferred to promises. Further research is needed to examine the causes of these results.     

Gender Role and Feminism Revisited: A Follow-Up Study

In this follow-up to our earlier study (Toller, Suter, & Trautman, Gender role identity and attitudes towards feminism, Sex Roles, 51, 85–90, 2004) we examine the interrelationships among gender role, support for feminism, and willingness to self-label as feminist. Ten percent of college students previously surveyed participated in qualitative interviews, which elicited characterizations of feminists, whether students self-identified as feminist, suggestions for garnering support for feminism, and for interpretation of the initial study’s findings. Students were asked to speculate why we found that highly masculine men and highly feminine women were neither likely to self-identify as feminist nor to support the feminist movement and why more feminine men and more masculine women were found to be more willing to self-label as feminist and more likely to support the feminist movement.     

Nanotoxicology and Ethical Conditions for Informed Consent

While their strength, electrical, optical, or magnetic properties are expected to contribute a trillion dollars in global commerce before 2015, nanomaterials also appear to pose threats to human health and safety. Nanotoxicology is the study of these threats. Do nanomaterial benefits exceed their risks? Should all nanomaterials be regulated? Currently nanotoxicologists cannot help answer these questions because too little is known about nanomaterials, because their properties differ from those of bulk materials having the same chemical composition, and because they differ so widely in their applications. Instead, this paper answers a preliminary ethical question: What nanotech policies are likely to contribute to society’s ability to give or withhold free informed consent to the potential risks associated with production and use of nanomaterials? This paper argues that at least four current policies appear to jeopardize the risk-disclosure condition that is required for informed consent. These are the funding problem, the conflict-of-interest problem, the labeling problem, and the extrapolation problem. Apart from future decisions on how to ethically make, use, and regulate nanomaterials, this paper argues that, at a minimum, these four policies must be modified. Government must spend greater monies on nanotoxicology; ensure independent nanotoxicology research; label consumer products containing nanomaterials; and avoid assuming that nanotoxicological properties are based merely on mass and chemical composition. Otherwise free informed consent to these new technologies and materials may be jeopardized.     

The “sexually abused child”: Potential mechanisms of adverse influences of such a label

Labeling and the effects of labeling have been extensively researched in the psychological literature in a variety of different contexts. For example, labeling has been empirically shown to lead to lowered expectancies of behavior and achievement, which can then contribute to the potential for the occurrence of a self-fulfilling prophecy with adverse consequences. Another area that has been extensively researched, with a dramatic increase in the literature base in recent history, is that of child sexual abuse (CSA). Despite various shortcomings of the research literature, the consistent findings have been identification of a variety of negative correlates and symptomatologies associated with CSA. In addition to any direct, negative effects of CSA, there may also be an additional impact from the “label” itself. Although the literature pertaining to CSA and labeling runs deep independently, efforts at addressing the issue of CSA within a labeling contextual framework have been minimal. To that end, this article examines hypothesized mechanisms of how the “sexual abuse” label may potentially have an adverse influence on the children subjected to such a label. The implications of an analysis, which addresses childhood sexual abuse from such a theoretical framework, may be a broader and more holistic understanding of the complexities and sequelae associated with CSA.
