In order to test the effectiveness of the debate of the candidates for the president, researchers randomly contacted 1000 people

on the phone. An attempt was made to contact all 1000 one day before the debate and ask their voting intentions. Only 910 were actually reached by phone; 80 out of the 910 people refused to participate. One day after the debate, 810 of the 910 people were reached and again asked their voting intentions. In addition they were asked if they had seen the debate on television. The before-after change of the viewers and non-viewers were compared to conclude which candidate was more effective in the debate. What kind of experimental design is being used? Describe relevant potential extraneous variables in this experiment. Can this experiment design rule out these extraneous variables?

RideAnS [48]

Heuristics are mental shortcuts that provide serviceable but often inexact answers to common judgmental problems.

<h3>What is Heuristics?</h3>

Heuristics are general principles that can be used to direct decision-making based on a more constrained subset of the information at hand. Heuristics are thought to enable quicker decision-making than techniques that require more information because they rely on less information.

The three heuristics that attracted the greatest attention are:

  • Anchoring,
  • Adjustment,
  • Availability.

Heuristics allows to quickly handle information volumes that are greater than what our social cognitive abilities can handle. These mechanisms play a role in the fact that most of our social thought happens automatically.

中文泛指汉语语族及其书写系统。现代汉语(普通话)是世界上使用人数最多的语言。使用人数已达到十七亿以上。在中国,大陆使用简体汉字,港澳台地区使用繁体汉字。海外华人地区多使用繁体汉字。汉字的起源,有传说中的仓颉造字。我们现在能够确认距今约3000多年的甲骨文已经是非常成熟的文字体系,于1899年被发现。可以考证的汉字发展经历了甲骨文、金文、小篆、汉隶、楷书、行书、草书等过程,可以划分为两个大阶段。从甲骨文字到小篆是一个阶段;从秦汉时代的隶书以下是另一个阶段。前者属于古文字的范畴,后者属于近代文字的范畴。大体说来,从隶书到今天使用的现代汉字形体上没有太大的变化。从汉字跟汉语的关系看,汉字是一种语素文字。汉字代表的是汉语里的语素。汉字有独体字与合体字的区别。从构造上讲,合体字比独体字高一个层次 。合体字可以分成以下 3 类:①形声字。由表示意义的形旁和表示读音的声旁两部分组成;②合体会意字。是会合偏旁的字义来表现整个合体字的意义;③合体记号字。这种合体字的偏旁既不表意,也不表音。跟拼音文字相比,汉字最大的长处是能够超越空间和时间的限制,汉语是全世界唯一的三维文字,既有表音,又有表意,还有表形,是现阶段人类文明中最稳固也是最先进的语言体系 。
