特邀编辑的几句话

大约两年前回国,<心理学报>的主编杨玉芳老师要我帮忙组一期行为遗传学的专辑.组稿的初衷是向国内同行介绍行为遗传学的最新发展.行为遗传学,顾名思义,也就是研究遗传因素如何对行为发生影响的学问.传统的行为遗传学主要借助孪生子及养子女作为手段,加以统计量化分析,以推算遗传和环境对行为,情感,认知,或智商等心理特征的影响.     

A few minor suggestions.

We agree with almost all of the analysis in this excellent presentation of the molecular view of avoidance behavior. A few suggestions are made as follows: Referring to response-generated stimuli as 'readily observable" seems not quite right for the kinesthetic components of such stimuli, although their scientific legitimacy is not questioned. Interpreting response-generated stimuli as a form of positive reinforcement is contested, and an alternative interpretation is offered. A possibly simpler interpretation of the Sidman (1962) two-lever experiment is suggested. We question Dinsmoor's (2001) explanation for warning stimuli not being avoided, except for the reference to the weakness of third-order conditioning effects. A final question is raised regarding the nature of the variables that are responsible for the momentary evocation of the avoidance response.
