    大学生心理健康教育的服务对象主要面向 人群。

    有关心理健康标准的描述正确的是:

    心理学家卡普兰指出,心理危机是当个体面临突然或重大生活逆遇时所出现的心理失衡状态。即,心理危机的发生必须同时满足的条件是:

    心理危机者可能出现的结果是:

    心理健康与不健康是泾渭分明的两极对立,很容易区分出来。

    只有严重心理问题的人才需要心理咨询。

    发展性危机被认为是正常的、可预见的危机。

    心理危机是无法预测和识别的。

    关于女性身体意象描述正确的是:

    身体意象失调,又称负面身体自我,是个体对身体的消极认知、消极情感体验和相应的行为调控,它包含对体重、体形和食物等信息的刻板化、情绪化和过分强调的评价。根据上述定义,下列不属于身体意象失调的是:

    领导力是指影响群体实现共同目标的协调、组织、 和指导指挥能力。

    以下选项中,属于个体幸福感表现的选项是:

    女性中年龄层次低者,倾向体型误认为较胖重,体型满意度较低。

    每个人都可以想着如何让自己过得舒服快乐就行,不用考虑事件相关他人的感受,这是爱自己、也是提升幸福感的一种策略。

    幸福是外部环境及他人所决定的,不是自己能够找到的。

    领导力的核心是影响力。

    印象管理又称印象整饰,是指人们试图 他人对自己所形成的印象的过程。

    保护性印象管理的策略有:合理化理由、事先申明、 、道歉等。

    以下选项中,属于在宿舍关系中主动与室友有效沟通的做法是:

    属于和谐宿舍关系的特点的有:

    印象管理可以简单分类为获得性印象管理、保护性印象管理和非言语印象管理三类。

    善于恰当自我表露的人不仅更受人喜欢,而且往往还被看做是个体适应良好的表现。

    在宿舍关系中,“自我中心”是爱自己的表现,对他人没有负面影响。

    在与人交往中,若他人能够包容自己,说明自己招人喜欢。

    斯滕伯格的爱情理论认为,只有和承诺,没有亲密关系的爱情是以下哪一种爱情模式:

    爱情与喜欢的区别:

    爱情心理学的一项研究表明,由独立观察者(夫妻双方单独)进行判定,相处出超过25年的夫妻面部的特征会越来越相似。这项研究中导致这个现象的原因主要有以下那几种?

    被分手后该怎么去摆脱负面情绪:

    心理学家斯滕伯格提出的爱情理论,认为爱情由、承诺和依恋三个成分组成。

    对越熟悉的东西越喜欢的现象,心理学上成为“光环效应”。

    “罗密欧与朱丽叶”效应,就是出现干扰恋爱双方爱情关系的外在力量时,恋爱双方的情感反而会更加强,恋爱关系也因此更加牢固。

    绝大多数人失恋的人,能够在三个月之后,重新进入正常的生活状态,但是失恋后的痛苦仍会存在,只不过没有曾经那么强烈了。

    原生家庭是指:

    如果原生家庭对一个人的影响,会影响哪几个方面?

    在绘制家谱图时,可用特定的线条和图案来描述基本家庭成员以及彼此之间关系,以下描述正确的是:

    与原生家庭和解,你认为正确的做法是:

    研究认为亲密关系中所碰到的一些瓶颈、碰到一些痛苦、一些冲动的反应,大概只有10%跟当前的人跟事有关系,90%可能是跟原生家庭有关系。

    家谱图是其以图的形式描述家庭从祖父母到自己三代人的血亲关系和婚姻关系。

    透过家谱图,往往可以一目了然发现过去没有发现的问题,对这些问题的自我发现有助于激发自我改变。

    原生家庭对一个人有很大影响,并且是起决定性作用的。
