Future time perspective drives younger and older adults to continue investing in failing activities

Inspired by socioemotional selectivity theory, we investigated age differences in further investment in failing situations by considering goal type and future time perspective. In Experiment 1, 32 younger and 30 older adults reported their likelihood of continued investing following an unsuccessful investment. Older adults were more willing to invest with emotional goals as opposed to knowledge and unspecified goals, while younger adults showed a greater willingness to invest with emotional and knowledge goals rather than unspecified goals. In Experiment 2, another sample of 32 younger and 34 older adults completed the same decision tasks as those in Experiment 1. After future time perspective restriction, the younger adults made decisions resembling Experiment 1's older adults, while after future time perspective expansion, the older adults behaved like Experiment 1's younger adults. These results indicate that future time perspective modification could reverse participants' goal prioritisation, manifesting in differential willingness to pursue further investment in decision scenarios with different goals. Our results represent important steps towards understanding the mechanism of older and younger adults' further investment in failing situations and illustrate that forging connections between the lifespan theory of motivation and further investment decision is critical for understanding adults' decision behaviours.     

Type development in childhood and beyond

This article defines and explains type development across the lifespan and summarizes what other researchers have presented as a reference. A timeline for development is identified, and ways to differentiate development of a function from the development of other personality characteristics are described. Type development is about the dispersion of energy from an unconscious level to a managed conscious level. This development occurs in a spiral pattern, so development of each function occurs repeatedly but at higher levels of use and understanding each time. Although the dominant function develops most because of its innate drive to be the lead, each function can develop throughout the lifespan. The relative energy associated with each function always exists. When the energy is in the unconscious, it drives behavioural responses, but these are not within the individual’s control. The ideal is to develop the conscious awareness of each of the functions so each can be consciously used as needed to match a situation. Because development of the functions is essential, this article examines potential interferences with development and then offers some suggestions for ways to promote developmental opportunities.     

中小学生欺负/受欺负的普遍性与基本特点

利用修订的Olweus欺负问卷对 92 0 5名城乡儿童进行了测查 ,考察初中和小学阶段儿童欺负 /受欺负问题的普遍性及基本特点。结果发现 :中小学生中存在着较严重的欺负问题 ,近 1/ 5被调查的儿童卷入欺负 /受欺负问题 ;总体上小学和初中阶段学生欺负 /受欺负问题的发生率随年级的升高而下降 ,但欺负他人在初中阶段具有稳定性 ;直接言语欺负是最为普遍的欺负方式 ;在欺负 /受欺负的比率、对待欺负态度和欺负类型上均存在性别差异。     

材料类型和颜色典型性影响颜色-物体Stroop效应

通过两个实验考查材料类型和颜色典型性对颜色-物体Stroop效应的影响。实验1,考查颜色-物体（图片）Stroop效应。结果颜色典型性差异显著,命名图片的颜色和图片的名称都产生显著的颜色-物体Stroop效应。实验2,考查颜色-物体（词语）Stroop效应。结果颜色典型性差异显著,命名词语的颜色产生颜色-物体Stroop效应,命名词语的名称未产生颜色-物体Stroop效应。结论,材料类型和颜色典型性影响颜色-物体Stroop效应。     

中介效应的点估计和区间估计:乘积分布法、非参数Bootstrap和MCMC法

针对中介效应ab的抽样分布往往不是正态分布的问题,学者近年提出了三类无需对ab的抽样分布进行任何限制且适用于中、小样本的方法,包括乘积分布法、非参数Bootstrap和马尔科夫链蒙特卡罗(MCMC)方法.采用模拟技术比较了三类方法在中介效应分析中的表现.结果发现:1)有先验信息的MCMC方法的ab点估计最准确;2)有先验信息的MCMC方法的统计功效最高,但付出了低估第Ⅰ类错误率的代价,偏差校正的非参数百分位Bootstrap方法的统计功效其次,但付出了高估第Ⅰ类错误率的代价;3)有先验信息的MCMC方法的中介效应区间估计最准确.结果表明,当有先验信息时,推荐使用有先验信息的MCMC方法;当先验信息不可得时,推荐使用偏差校正的非参数百分位Bootstrap方法.     

“美男诱惑”真的奏效吗:男性代言女性产品对女性消费者产品评价的影响

男性代言女性产品的广告策略真的奏效吗?本文旨在探讨女性产品代言人性别与女性消费者对该产品评价之间的关系。4个实验的结果显示,与女性代言女性产品相比,男性代言时女性消费者对该产品的评价会显著降低。该影响是通过身份威胁感的中介实现的。此外,身份肯定对该效应存在调节作用。具体来讲,当被试受到女性身份肯定操控时,主效应会加强。本文实证研究了男性代言女性产品可能带来的负面效应,基于性别认同一致性理论拓展了产品性别属性的下游结果。

污染效应在消费者行为领域的表现及其心理机制

随着健康问题越来越受到消费者的重视, 学者们对污染效应的研究和兴趣也与日俱增, 特别是在消费者的感知和偏好方面。在消费者行为研究中, 污染效应是指消费者会降低对他人接触过产品的感知价值。本研究主要回顾了在消费行为中污染效应的定义和特性, 然后从接触因素、位置因素、产品因素和社会因素等方面来探讨污染效应的前因, 并进一步归纳了污染效应对消费者行为的消极影响和积极影响。最后, 探讨了污染效应的理论基础和边界条件。在此基础上, 对污染效应在消费者行为领域的未来研究方向进行了展望。     

外周型原始神经外胚层肿瘤1例

原始神经外胚叶肿瘤是一种罕见的、起源于原始神经上皮的恶性小圆形细胞肿瘤,具有多方向分化能力,可发展为神经元性的、胶质细胞性的、甚至间叶组织性质的肿瘤.根据发病部位将其分为中枢型和外周型两种,中枢型多发于脑和脊髓,外周型多见于胸壁、四肢,发生于脊柱者少见.本文就外周型原始神经外胚层肿瘤1例做病例报道,总结该类肿瘤的特点,肿瘤密度/信号不均匀,轻至中度强化,预后差,临床治疗手段主要为外科手术辅以放化疗,术前行增强CT对手术可切除性评估非常有价值.
