In two experiments we investigated the relation between power and deception in ultimatum bargaining. Results showed that recipients of an ultimatum used deception to obtain better offers and that more recipients did so in a low power position. Further analyses showed that the recipient’s use of deception was mediated by concerns about receiving a low offer. For allocators, being in a low power position did not increase the use of deception. Instead, allocators increased their offer when they were in a low power position. The results are discussed in terms of an instrumental approach to deception. This approach incorporates the notion that bargainers (a) will use deception as a means to reach their goals in bargaining but (b) may refrain from using deception when they have alternative means to reach their goals. 相似文献

Pronouns encouraging a second‐person perspective (e.g., “you/your”) affect peoples' mental representations constructed while reading and improve learning. The present study applied these insights to a domain in that such pronoun effects have yet been unexplored: mathematical word problem solving. Specifically, we encouraged a second‐person perspective (using “your”) in an attempt to reduce the consistency effect, that is, the finding that more errors are made on word problems containing a relational keyword inconsistent rather than consistent with the required arithmetic operation. Primary school children solved consistent and inconsistent word problems (containing the relational keywords “less than”) presented in third‐person (i.e., store name) or second‐person (“your store”) perspective. Results demonstrated the consistency effect, but the perspective manipulation did not produce significant differences between conditions, that is, a second‐person perspective did not reduce the consistency effect. These findings suggest that reducing the consistency effect may require a less subtle approach than using personalized pronouns. 相似文献

The objective of this document is to provide recommendations for genetic counseling and screening for consanguineous couples (related as second cousins or closer) and their offspring with the goals of1. providing preconception reproductive options2. improving pregnancy outcome and identifying reproductive choices3. reducing morbidity and mortality in the 1st years of life, and4. respecting psychosocial and multicultural issues.The recommendations are the opinions of a multicenter working group (the Consanguinity Working Group (CWG)) with expertise in genetic counseling, medical genetics, biochemical genetics, genetic epidemiology, pediatrics, perinatology, and public health genetics, which was convened by the National Society of Genetic Counselors (NSGC). The consensus of the CWG and NSGC reviewers is that beyond a thorough medical family history with follow-up of significant findings, no additional preconception screening is recommended for consanguineous couples. Consanguineous couples should be offered similar genetic screening as suggested for any couple of their ethnic group. During pregnancy, consanguineous couples should be offered maternal–fetal serum marker screening and high-resolution fetal ultrasonography. Newborns should be screened for impaired hearing and detection of treatable inborn errors of metabolism. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. The professional judgment of a health care provider, familiar with the facts and circumstances of a specific case, will always supersede these recommendations. 相似文献

A review of previous studies on children's comprehension of visual formal features did not warrant predictions about children's understanding of the formal features as used in three items from Sesamstraat, the Dutch version of Sesame Street. Therefore, a study was designed in which 45 children in the age range of 4–6 years watched the items and were interviewed. In the first item, a split screen was used to visualize simultaneity of actions. The second item used a subjective camera to suggest the construction of a home video by one of the characters. Version 1 of this item did not show the character while making home video, whereas Version 2 did show the character while filming. The third item contained a dissolve (Version 1) or a cut (Version 2) to indicate the end of a dream. A general conclusion was that although older children (mean AGE=5.9 years) understood the visual formal features better than younger children (mean AGE=4.4 years), the extent to which children in both age groups understood the visual formal features appeared to vary between items and versions. Most children in both age groups understood the split screen in the first item. The younger age group did not understand the subjective camera if the making of the home video was not shown. Both the younger and the older age group understood the version with the cut better than the original version with the dissolve. In the discussion, the question was addressed what the findings of this study and previous studies teach us about children's understanding of visual formal features in general. 相似文献

A major problem in learning from instructional animations is that the complex perceptual and cognitive processing exceeds the learner's limited processing capacities. Although attention cueing might help learners in focusing on essential parts of an animation, previous studies have shown that it does not necessarily improve learning performance. This study investigated whether generating self‐explanations while studying a cued or an uncued animation might engage learners in cognitive activities necessary for learning. It was hypothesized that learning from a cued animation that reduces working memory load associated with searching for specific elements might be improved by generating self‐explanations, whereas self‐explaining with an uncued animation would have no positive effect on learning. The results confirmed the hypothesized interaction between cueing and self‐explaining. They suggest that self‐explanation enhances learning if visual cues are used to structure and highlight the essential parts of an animation. Copyright © 2010 John Wiley & Sons, Ltd. 相似文献

Background
Self-management of cognitive load is a recent development in cognitive load theory. Finger pointing has been shown to be a potential self-management strategy to support learning from spatially separated, but mutually referring text and pictures (i.e., split-attention examples).Aims
The present study aimed to extend the prior research on the pointing strategy and investigated the effects of finger pointing on learning from online split-attention examples. Moreover, we examined an alternative pointing strategy using the computer mouse, and a combination of finger pointing and computer-mouse pointing.Sample
One-hundred and forty-five university students participated in the present study.Method
All participants studied an online split-attention example about the human nervous system and were randomly allocated to one of four conditions: (1) pointing with the index finger, (2) pointing with the computer mouse, (3) pointing with the index finger and the computer mouse and (4) no pointing.Results
Results confirmed our main hypothesis, indicating that finger pointing led to higher retention performance than no pointing. However, the mouse pointing strategy and the combined finger and mouse pointing strategy did not show supportive effects.Conclusions
Finger pointing can be used as a simple and convenient self-management strategy in online learning environments. Mouse pointing may not be as effective as finger pointing. 相似文献39.

Recognition tasks of simple visual patterns have been used to assess an early visual--auditory sensory-substitution system, consisting of the coupling of a rough model of the human retina with an inverse model of the cochlea, by means of a pixel-frequency relationship. The potential advantage of the device, compared with previous ones, is to give the blind the ability to both localise and recognise visual patterns. Four evaluation sessions assessed the performance of twenty-four blindfolded sighted subjects using the device. Subjects had to recognise twenty-five visual patterns, one at a time, using a head-mounted small camera and interpreting the corresponding sounds given by the device. Half the subjects were trained by means of a correction feedback procedure during ten one-hour training sessions embedded in between the evaluation sessions. Results revealed extremely successful training effects. Performance of trained subjects significantly increased with practice compared with the untrained control group. The improvement was also observed for new patterns, demonstrating a learning-process generalisation. The negative correlation observed between scores and processing time showed that the subjects' response accuracy was related to their speed. In conclusion, simple pattern recognition is possible with a fairly natural vision-to-audition coding scheme, given the possibility for the subjects to have sensory--motor interactions while using the device. 相似文献
