A social-cognitive approach to understanding gender differences in negotiator ethics: The role of moral identity
To date, gender differences in ethics have received little theoretical attention. We utilize a social-cognitive framework to explain why these differences emerge and when women engage in less unethical negotiating behavior than do men. We propose that, relative to men, women’s stronger moral identities suppress unethical negotiating behavior. Study 1 establishes a gender difference in moral identity strength through a meta-analysis of over 19,000 people. Study 2 observes gender differences in two aspects of negotiator ethics – moral disengagement and opportunism. Study 3 establishes moral identity strength as an antecedent to negotiator ethics. Finally, Studies 4 and 5 explore financial incentives as a situational moderator. Because financial incentives temporarily decrease the salience of moral identity, they could mitigate gender differences in negotiator ethics, leading women to act more like men. Across both studies, financial incentives impacted women’s (but not men’s) unethical negotiating behavior. Our findings help to explain why and when gender differences in ethics emerge
Metacognitive scaffolding boosts cognitive and neural benefits following executive attention training in children
Version of Record online: 25 October 2018Interventions including social scaffolding and metacognitive strategies have been used in
educational settings to promote cognition. In addition, increasing evidence shows that
computerized process-based
training enhances cognitive skills. However, no prior studies
have examined the effect of combining these two training strategies. The goal of this
study was to test the combined effect of metacognitive scaffolding and computer-based
training of executive attention in a sample of typically developing preschoolers at the
cognitive and brain levels. Compared to children in the regular training protocol and an
untrained active control group, children in the metacognitive group showed larger gains
on intelligence and significant increases on an electrophysiological index associated with
conflict processing. Moreover, changes in the conflict-related
brain activity predicted
gains in intelligence in the metacognitive scaffolding group. These results suggest that
metacognitive scaffolding boosts the influence of process-based
training on cognitive
efficiency and brain plasticity related to executive attention.Secretaría de Estado de Investigación,

Automated sample-processing and titration system for determining uranium in nuclear materials
The system is designed for accurate, precise, and selective determination of from 10 to 180 mg of uranium in 2 to 12 cm/sup 3/ of solution. Samples, standards, and their solutions are handled on a weight basis. These weights, together with their appropriate identification numbers, are stored in computer memory and are used automatically in the assay calculations after each titration. The measurement technique (controlled-current coulometry) is based on the Davies-Gray and New Brunswick Laboratory method, in which U(VI) is reduced to U(IV) in strong H/sub 3/PO/sub 4/, followed by titration of the U(IV) with electrogenerated V(V). Solution pretreatment and titration are automatic. The analyzer is able to process 44 samples per loading of the sample changer, at a rate of 4 to 9 samples per hour. The system includes a comprehensive fault-monitoring system that detects analytical errors, guards against abnormal conditions which might cause errors, and prevents unsafe operation. A detailed description of the system, information on the reliability of the component subsystems, and a summary of its evaluation by the New Brunswick Laboratory are presented
Too Masculine, Too Bad Effects of Communion on Leaders’ Promotion of Cooperation
This study challenges researchers and practitioners in the field of leadership to consider communion as a relevant variable for (male) leadership effectiveness. We suggest that communal traits influence the ability of male leaders to engender cooperation and that this effect is stronger in male-dominated contexts. We argue that this is because relevant traits and leadership behaviors that underscore a sense of community are associated with stereotypically feminine roles and identity. In a series of three studies, experimental as well as survey-based, using Spanish, Dutch, and American samples, we examined such gendered construction of male leadership and its effects on cooperation. Among others, results are discussed in terms of how stereotypically masculine constructions of male leadership may create barriers to effective leadership
Autonomous indoor wayfinding for individuals with cognitive impairments
<p>Abstract</p> <p>Background</p> <p>A challenge to individuals with cognitive impairments in wayfinding is how to remain oriented, recall routines, and travel in unfamiliar areas in a way relying on limited cognitive capacity. While people without disabilities often use maps or written directions as navigation tools or for remaining oriented, this cognitively-impaired population is very sensitive to issues of abstraction (e.g. icons on maps or signage) and presents the designer with a challenge to tailor navigation information specific to each user and context.</p> <p>Methods</p> <p>This paper describes an approach to providing distributed cognition support of travel guidance for persons with cognitive disabilities. A solution is proposed based on passive near-field RFID tags and scanning PDAs. A prototype is built and tested in field experiments with real subjects. The unique strength of the system is the ability to provide unique-to-the-user prompts that are triggered by context. The key to the approach is to spread the context awareness across the system, with the context being flagged by the RFID tags and the appropriate response being evoked by displaying the appropriate path guidance images indexed by the intersection of specific end-user and context ID embedded in RFID tags.</p> <p>Results</p> <p>We found that passive RFIDs generally served as good context for triggering navigation prompts, although individual differences in effectiveness varied. The results of controlled experiments provided more evidence with regard to applicabilities of the proposed autonomous indoor wayfinding method.</p> <p>Conclusions</p> <p>Our findings suggest that the ability to adapt indoor wayfinding devices for appropriate timing of directions and standing orientation will be particularly important.</p

Enhancing preschoolers' executive functions through embedding cognitive activities in shared book reading
Given evidence that early executive functioning sets the stage for a broad range of subsequent
outcomes, researchers have sought to identify ways to foster these cognitive capacities. An
increasingly common approach involves computerized ‘brain training’ programs, yet there are
questions about whether these are well suited for fostering the early development of executive
functions (EFs). The current series of studies sought to design, develop, and provide evidence for the
efficacy of embedding cognitive activities in a commonplace activity – shared reading of a children’s
book. The book, Quincey Quokka’s Quest, required children to control their thinking and behaviour to
help the story’s main character through a series of obstacles. The first study investigated effects of
reading with embedded cognitive activities in individual and group contexts on young children’s
executive functions (EFs). The second study compared reading with embedded cognitive activities
against a more-active control condition (dialogic reading) that similarly engaged children in the
reading process yet lacked clear engagement of EFs. The third study sought to investigate whether the
effect of reading the story with embedded EF activities changed across differing doses of the
intervention and whether effects persisted 2 months post-intervention. Findings provide converging
evidence of intervention effects on working memory and shifting in as little as 3 weeks (compared to
more traditional reading) and maintenance of these gains 2 months later. This suggests the efficacy of
embedding cognitive activities in the context of everyday activities, thereby extending the range of
users and contexts in which this approach can be used
When is working memory important for arithmetic?: the impact of strategy and age
Our ability to perform arithmetic relies heavily on working memory, the manipulation and maintenance of information in mind. Previous research has found that in adults, procedural strategies, particularly counting, rely on working memory to a greater extent than retrieval strategies. During childhood there are changes in the types of strategies employed, as well as an increase in the accuracy and efficiency of strategy execution. As such it seems likely that the role of working memory in arithmetic may also change, however children and adults have never been directly compared. This study used traditional dual-task methodology, with the addition of a control load condition, to investigate the extent to which working memory requirements for different arithmetic strategies change with age between 9-11 years, 12-14 years and young adulthood. We showed that both children and adults employ working memory when solving arithmetic problems, no matter what strategy they choose. This study highlights the importance of considering working memory in understanding the difficulties that some children and adults have with mathematics, as well as the need to include working memory in theoretical models of mathematical cognition
Where Snow is a Landmark: Route Direction Elements in Alpine Contexts
Route directions research has mostly focused on urban space so far, highlighting human concepts of street networks based on a range of recurring elements such as route segments, decision points, landmarks and actions. We explored the way route directions reflect the features of space and activity in the context of mountaineering. Alpine route directions are only rarely segmented through decision points related to reorientation; instead, segmentation is based on changing topography. Segments are described with various degrees of detail, depending on difficulty. For landmark description, direction givers refer to properties such as type of surface, dimension, colour of landscape features; terrain properties (such as snow) can also serve as landmarks. Action descriptions reflect the geometrical conceptualization of landscape features and dimensionality of space. Further, they are very rich in the semantics of manner of motion
