Looking for ideas: Eye behavior during goal-directed internally focused cognition

Humans have a highly developed visual system, yet we spend a high proportion of our time awake ignoring the visual world and attending to our own thoughts. The present study examined eye movement characteristics of goal-directed internally focused cognition. Deliberate internally focused cognition was induced by an idea generation task. A letter-by-letter reading task served as external task. Idea generation (vs. reading) was associated with more and longer blinks and fewer microsaccades indicating an attenuation of visual input. Idea generation was further associated with more and shorter fixations, more saccades and saccades with higher amplitudes as well as heightened stimulus-independent variation of eye vergence. The latter results suggest a coupling of eye behavior to internally generated information and associated cognitive processes, i.e. searching for ideas. Our results support eye behavior patterns as indicators of goal-directed internally focused cognition through mechanisms of attenuation of visual input and coupling of eye behavior to internally generated information.     

文化背景与医疗行为:一个少数民族社区中的新型农村合作医疗

现有对民族社区新型农作合作医疗（以下简称新农合）的研究相对较少,同时在研究中忽略了在其独特民族文化背景下对于疾病与医疗的不同认知,这一认知影响了人们的医疗观念和医疗行为,也直接影响了人们对新农合的态度和行为。医学人类学关注文化与疾病、医疗的关系,以云南省福贡县赤恒底傈僳族社区新农合的田野调查为例,应用医学人类学的视角和社区研究方法对其进行研究,以期获得新的认识和理解。     

Generating variable and random schedules of reinforcement using Microsoft Excel macros

Variable reinforcement schedules are used to arrange the availability of reinforcement following varying response ratios or intervals of time. Random reinforcement schedules are subtypes of variable reinforcement schedules that can be used to arrange the availability of reinforcement at a constant probability across number of responses or time. Generating schedule values for variable and random reinforcement schedules can be difficult. The present article describes the steps necessary to write macros in Microsoft Excel that will generate variable-ratio, variable-interval, variable-time, random-ratio, random-interval, and random-time reinforcement schedule values.     

Stress Generation in Adolescent Depression: The Moderating Role of Child Abuse and Neglect

The present study examined the role of childhood abuse and neglect and depression recurrence in moderating the generation of stressful life events in adolescent depression. Maltreatment history and stressful life events were assessed using two rigorous contextual interviews and rating systems. In a sample of 59 community depressed adolescents we found significantly higher rates of interpersonal events in the 3-month period immediately following depression episode onset versus the 3-month period immediately preceding onset in adolescents with a history of childhood maltreatment. By contrast, rates of events remained constant over a matched period in a control group of non-maltreated adolescents. Furthermore, the generation of interpersonal events only held among those on a first onset of depression. These results suggest that a history of childhood abuse and neglect exacerbates the psychosocial dysfunction associated with the onset of depression, particularly in the very first episode.     

代数应用题项目生成的结构分析方法

自动化项目生成是近年来兴起的测量领域, 是一种以项目认知加工理论为基础的原则性项目设计(principled item design)模式。其中, 如何在项目认知模型基础上, 通过任务结构分析的方式系统全面的鉴别和提取任务特征是一个关键环节。基于已有文献中代数应用题的命题分析法、网络语言分析法、关系-函数分析法、任务分析地图等四种结构分析方法, 研究探索了能够服务于自动化项目生成的代数应用题任务结构分析方法。该分析表明, 前三种方法分别对应于个体解题过程需要形成的三种中介表征, 即问题陈述背后的命题表征、事件时空关系的情境模型、以及变量间数量关系的问题模型, 第四种方法从过程角度分析了问题解决的认知需求。然而, 要实现项目生成的特征提取需求, 尚需对现有四种方法所揭示问题特征的心理现实性、特征提取的系统性和完备性、任务领域的适用范围、以及不同方法的整合等问题开展进一步研究。     

Generating leads with sequential persuasion: should sales influence tactics be consistent or complementary?

Firms are becoming increasingly systematic in sales lead generation activities and recognize that multiple interactions are often required to generate leads and to reassure buyers of the benefits of an offering. However, the literature is contradictory regarding what types of persuasive messages should be used across these multiple interactions. This paper investigates what combination of sales influence tactics (SITs) should be used when customers are approached more than once regarding the same offering, that is, sequentially. Should the SITs be consistent (the same), or complementary (different)? Consistent vs. complementary SIT approaches were tested in two field experiments, one with an electronics manufacturer in a single communication channel setting and one with a financial services provider in a cross-channel setting. The results supported our hypothesis and indicated that the use of complementary SITs across interactions, regardless of the order, increases lead conversion.     

Destruction and guilt: Splitting and reintegration in the analysis of a traumatised patient

The author traces in detail how, in the analytic relationship, she was slowly able to read aspects of the trauma as 'quotations' and gradually, through transference, transform them into a symbolic language. Split-off aggression and guilt feelings became progressively accessible to interpretation through transferential projective identifi cations. During his analysis, the patient discovered he was the child of Nazi criminals: on his mother's side they were the third generation; on his father's side, the second.     

论影响卫生资源分配公平性的因素

公平分配卫生资源是促进社会公正的重要方面.观念、体制与政策是影响卫生资源公平分配的重要因素.重医疗、轻预防的观念使宏观卫生资源分配失去公平,而城市尤其是大中城市优先的制度安排、按医疗项目付费方式的弊端、医疗保障体制的不公平等体制与政策因素则使微观卫生资源分配失去公平.从观念因素、体制与政策因素两个方面入手,改进卫生资源分配的公平性,是我国提高全民健康水平、促进社会公正的必由之路.     

Building on the ideas of others: An examination of the idea combination process

Two experiments were conducted to explore the process of building on ideas in brainstorming. Although this is presumed to be an important role of brainstorming, this has never been explored experimentally. In one experiment individual and group brainstormers generated ideas which were subsequently presented to these same individuals and groups to combine and build on for additional ideas, either as groups or individuals. The combination process was influenced by whether the participants had previously brainstormed alone or in groups and the phase of the combination period (early vs. late). In a second study participants were presented lists of rare or common ideas to combine and build on either as individuals or groups. Although groups generated fewer combinations than nominal groups, they generated more novel and feasible combinations when combining rare ideas. These findings indicate that groups are able to benefit from the exchange process in building on each other's ideas and are interpreted in the context of past research on idea generation and evaluation in groups.
