Enhanced happiness and stress alleviation upon insight meditation retreat: mindfulness,a part of traditional Buddhist meditation

This research aims to examine how traditional insight meditation in Thailand is trained and to investigate the impact of this practice on happiness and perceived stress. The fuller meaning of mindfulness and how to interweave mindfulness in daily practice is discussed. The intervention was a seven-day traditional insight meditation retreat in Thailand. The final sample included 656 participants, n?=?330 and 326 in experimental group and control group, respectively. Validated versions of happiness and perceived stress scales for Thai people were used. The magnitude of happiness and stress changes following the intervention, determined by effect sizes were used as a benchmark for interpreting the health status change between baseline and post-test. The effect sizes for happiness and perceived stress were .379 and ?.428 in the meditation group, which is much greater, compared to the effect sizes of ?.045 and ?.003, respectively, in the control group.     

Are good salespeople born or made? A new perspective on an age-old question: implicit theories of selling ability

Considering implicit theories in a sales context can provide a framework for better understanding salesperson motivation and behavior. The current research develops, tests, and examines the relevance of an Implicit Theories of Selling Ability (ITSA) measure, which measures the extent to which a person believes selling is an incremental (made) ability versus an entity (born) ability. After pre-testing the ITSA measure, two studies found an unfavorable pattern of outcomes associated with an entity belief of selling ability, consistent with research in other domains. Experimental validity for ITSA is demonstrated, thus supporting a direct relationship between ITSA and sales-relevant constructs, and suggesting manipulation of ITSA as a potential training intervention. This research extends past sales research on implicit theories by developing a sales-specific implicit theories measure and by examining goal orientations and behavior within the social-cognitive model (SCM). Conceptualizing sales performance behaviors from this SCM perspective reveals important considerations for both researchers and practitioners regarding salesperson hiring, training, and placement.     

Selling in an asymmetric retail world: perspectives from India,Russia, and the US on buyer–seller information differential,perceived adaptive selling,and purchase intention

The current research aimed to contribute to our understanding of (a) how adaptive selling is perceived by retail consumers in different types of economies when they have differing levels of buyer–seller information differential and (b) how this phenomenon influences their purchase intention. The focal countries were the US (a developed economy) and India and Russia (both developing economies). These three were selected owing to their disparate economic and cultural contexts. This investigation used a relatively new construct: perceived adaptive selling (PAS). PAS refers to the degree to which the buyer perceives that the salesperson is adapting. The study examined whether the impact of PAS was a function of a country’s level of development and whether such perceptions were influenced by the level of buyer–seller information differential in the retail transaction. The findings suggested that buyers in Russia and India PAS and were influenced by it differently from their US counterparts. This work provided a general framework for understanding tactical implementation of the salesperson’s PAS behavior.     

Insight in frontotemporal dementia: conceptual analysis and empirical evaluation of the consensus criterion "loss of insight" in frontotemporal dementia

The objective of this study was to suggest a new formulation of the core research diagnostic consensus criterion "loss of insight" in frontotemporal dementia (FTD). Eight patients with FTD (diagnoses made by interviews, medical and neuropsychological examination, CT scan, and regional cerebral glucose metabolism measured by positron emission tomography (PET) participated in the study). The results indicated that insight was present in three out of eight patients, and that insight appears to be a heterogeneous concept. Two types of insight emerged: Emotional insight associated with frontotemporal functions, and cognitive insight, related to posterior cognitive functions. These results suggest that loss of insight should not serve as a core criterion on FTD, but serves well as a supportive criterion of the disease.     

顿悟问题解决过程中抑制解除理论有效性的实验研究

本研究以Puzzle任务为材料,对135名高二学生特定线索下的操作水平进行测查,结果表明：（1）表征的抑制解除理论对顿悟问题解决的机制具有一定的解释效力,表现为总体上经历了高操作失败次数的被试在线索敏感性上明显高于未经历操作失败次数的被试。（2）而被试在特定阶段的操作水平未出现朝向解决目标的线性增长而是出现停滞的现象证明了问题的表征复杂性对抑制解除的过程存在制约作用,使其宏观上表现为渐进-停滞-跃升的变化模式。     

顿悟:是进程监控还是表征转换

当前解释顿悟问题解决机制的理论主要有表征转换理论和进程监控理论。进程监控理论主要解释了顿悟问题为什么困难,但事实上它并没有说明顿悟问题为什么会解决,只回答了在什么情况下被试才会寻求其他的方法,而且它把顿悟问题解决的一般过程看成是同常规问题解决方法相同的过程。而表征转换理论主要解释了顿悟是如何获得的——顿悟的获得是由于问题解决者对问题的表征实现了正确的转变,但它并没有解释表征什么时候、怎么样才能转变?顿悟问题的解决经历了三个认知加工阶段,顿悟问题的解决需要在消除定势情况下激活正确的启发信息(线索),并验证了顿悟问题的原型激活和关键启发信息理论假说。     

Categories of insight and their correlates: An exploration of relationships among classic‐type insight problems,rebus puzzles,remote associates and esoteric analogies

A central question in creativity concerns how insightful ideas emerge. Anecdotal examples of insightful scientific and technical discoveries include Goodyear's discovery of the vulcanization of rubber, and Mendeleev's realization that there may be gaps as he tried to arrange the elements into the Periodic Table. Although most people would regard these discoveries as insightful, cognitive psychologists have had difficulty in agreeing on whether such ideas resulted from insights or from conventional problem solving processes. One area of wide agreement among psychologists is that insight involves a process of restructuring. If this view is correct, then understanding insight and its role in problem solving will depend on a better understanding of restructuring and the characteristics that describe it. This article proposes and tests a preliminary classification of insight problems based on several restructuring characteristics: the need to redefine spatial assumptions, the need to change defined forms, the degree of misdirection involved, the difficulty in visualizing a possible solution, the number of restructuring sequences in the problem, and the requirement for figure‐ground type reversals. A second purpose of the study was to compare performance on classic spatial insight problems with two types of verbal tests that may be related to insight, the Remote Associates Test (RAT), and rebus puzzles. In doing so, we report on the results of a survey of 172 business students at the University of Waikato in New Zealand who completed classic‐type insight, RAT and rebus problems.     

顿悟的原型启发效应机制探索

以中国传统的字谜作为实验材料,采用"多个原型字谜学习-多个目标字谜测试"两阶段实验范式,对顿悟过程的原型启发机制进行了探讨.考察了原型启发效应是否会受第一阶段学习的原型字谜的数量以及启发量大小的影响,结果发现:学习的原型字谜的数量对原型启发效应的大小没有显著影响;启发量高低对原型启发效应的大小有显著影响.这一结果支持了"原型字谜的激活是一种自动加工、原型字谜中所隐含的关键启发信息的激活是一种控制加工"的观点.     

字谜问题解决中顿悟的原型启发机制再探

以中国传统字谜为实验材料,采用多对多的“学习-测试”二阶段实验范式和ERP记录手段,研究了原型字谜和靶字谜之间是否含有共同字词对顿悟的原型启发的影响。结果发现,在靶字谜呈现后的700ms内,正确解决有共同字词、无共同字词和基线条件字谜所诱发的脑电活动基本一致。在800-1700ms时间窗口内,有共同字词条件和无共同字词条件比基线条件诱发了一个更正的P800-1700成分,可能反映了原型启发下原型的激活和新颖联系的形成。此外,有共同字词条件和无共同字词条件诱发的波形始终趋于一致,可能表明字面上相同的字词并没有对原型启发产生影响,而原型字谜和靶字谜之间内在的语义联系才是原型启发的关键。     

顿悟的大脑机制

自从柯勒1917年提出顿悟的概念以来,这个问题一直吸引着心理学家的关注。但有关顿悟过程的精确的大脑机制却始终未被触及。从心理过程上看,顿悟是一个瞬间实现的、问题解决视角的“新旧交替”过程;它包含两个方面,一是新的有效的问题解决思路如何实现,二是旧的无效的思路如何被抛弃（即打破思维定势）。我们以谜语作为材料,利用功能性磁共振成像（fMRI）技术精确记录了人类的大脑在实现顿悟的一瞬间的活动状况。结果显示顿悟过程激活了包括额叶、颞叶、扣带前回、以及海马在内的广泛脑区。根据各方面的综合证据,本文认为：顿悟过程中,新异而有效的联系的形成依赖于海马,问题表征方式的有效转换依赖于一个“非语言的” 视觉空间信息加工网络,而思维定势的打破与转移则依赖于扣带前回与左腹侧额叶。
