Mobile Phones in the Bedroom: Trajectories of Sleep Habits and Subsequent Adolescent Psychosocial Development

Mobile phones are an essential part of an adolescent's life, leading them to text, phone, or message into the night. Longitudinal latent growth models were used to examine relations between changes in adolescent night‐time mobile phone use, changes in sleep behavior, and changes in well‐being (depressed mood, externalizing behavior, self‐esteem, and coping) for 1,101 students (43% male) between 13 and 16 years old. Both night‐time mobile phone use and poor sleep behavior underwent positive linear growth over time. Increased night‐time mobile phone use was directly associated with increased externalizing behavior and decreased self‐esteem and coping. Changes in sleep behavior mediated the relation between early changes in night‐time mobile phone use and later increases in depressed mood and externalizing behavior and later declines in self‐esteem and coping.     

关于手机依赖的研究综述

目前,手机依赖的研究对象主要集中在大学生和白领阶层。手机依赖的概念有从医学角度出发的,有从心理学角度出发的,还有从社会学角度出发的。手机依赖产生的原因主要有从众心理、娱乐需求、情绪情感因素以及发展需要等。至于手机依赖的干预,则缺乏切实有力的策略。     

高校大学生废旧手机回收行为调查研究

大学里废旧手机的产生量大且集中,对高校学生的手机回收行为做了问卷调查。结果显示:大学生手机的使用数量高于普通家庭,淘汰周期比国内及世界一般地区的大多数居民消费者短。分析了处理废旧手机的常见做法、废旧手机长期闲置和回收率低的原因以及促使手机回收的激励措施;还分析了大学生的环境意识和支付意愿,很多大学生的环保意识较高,但环保行为较差,在能接受的处置费用比例中,大部分学生选择了较低的比例;此外,在调查分析的基础上,分别提出了提高大学生废旧手机回收率的措施和建议。     

大学生手机使用和学业倦怠关系研究

采用问卷调查的方法考察了大学生手机使用和学业倦怠之间的关系,调查数据显示:大学生手机使用状况总体良好,但部分学生有过度使用的倾向;手机过度使用总分、强迫性、戒断性和冲突性都和学业倦怠总分、情绪低落、行为不当等因子呈正相关,强迫性可以预测学业倦怠状况;在学业倦怠总分及其各因子上,手机使用高分组和低分组差异显著.结果表明:大学生手机使用尚处于正常水平,日常心理健康教育应加强大学生的意志力和行为控制能力的培养.     

大学生手机依赖状况调查及对策

手机移动学习方式在大学生英语听力学习中的应用

近年来,继数字化学习之后出现了一种新的学习模式——移动学习(M-Learning),其最大的特点就是能实现在Anyone、Anytime、Anywhere、Any style(4A)下进行自由的学习。基于手机的移动学习就是利用手机移动通讯设备来进行随时随地随意的学习,其学习不受时间、空间和地域的限制。依据调查和访谈,在较全面地了解大学生对利用手机移动学习方式学习英语的态度的基础上,分析了现在大学生利用手机学习英语听力的方式,以及制约大学生利用手机来学习英语听力的相关因素。     

Effects of Mobile Phones on Children's and Adolescents’ Health: A Commentary

The use of digital technology has grown rapidly during the last couple of decades. During use, mobile phones and cordless phones emit radiofrequency (RF) radiation. No previous generation has been exposed during childhood and adolescence to this kind of radiation. The brain is the main target organ for RF emissions from the handheld wireless phone. An evaluation of the scientific evidence on the brain tumor risk was made in May 2011 by the International Agency for Research on Cancer at World Health Organization. The scientific panel reached the conclusion that RF radiation from devices that emit nonionizing RF radiation in the frequency range 30 kHz–300 GHz is a Group 2B, that is, a “possible” human carcinogen. With respect to health implications of digital (wireless) technologies, it is of importance that neurological diseases, physiological addiction, cognition, sleep, and behavioral problems are considered in addition to cancer. Well‐being needs to be carefully evaluated as an effect of changed behavior in children and adolescents through their interactions with modern digital technologies.     

中介语发展过程中僵化现象探析

中介语的僵化现象是二语习得领域中的一个重要课题。作为一种独特的语言体系，中介语有其自身特点和发展阶段。其僵化现象产生原因众多，主要可归结为内部因素和外部因素。只要学习者采取一定措施，可以解冻中介语僵化现象．以提高二语习得的效果。     

浅谈手机短信语言的特点

语言是人类最重要的交际工具,同时也是人们娱乐和游戏的工具,从广义上看,娱乐和游戏也是一种交际,手机短信就是轻松巧妙地在语言文字游戏中完成传情达意的任务的。手机短信受其载体———手机的特殊性质的影响,语言表现出不同于其他群体语言的特点。主要是:受字数限制,精练简洁;屏幕显示可以制造特殊的幽默效果;大量使用多种修辞格,使短信表达生动形象、妥切鲜明;标点、数字和特殊字符的妙用为短信语言增添了一种别样的色彩。     

The Effects of Attention Cueing on English Reading on Mobile Phones

The purpose of this quasi-experimental study is to examine whether attention cueing benefits learners of ancient Egyptian culture using mobile-assisted instrumentation. A self-regulatory, mobile phone based set of visualizations depicting ancient Egyptian culture served as the primary instrument. A total of 50 learners of English as a foreign language (EFL) from two sections of a reading course were randomly assigned to one of two groups. First, the participants were tested to assess their English reading level and prior knowledge of Egyptian culture. Next, they were randomly assigned to one of two modes: picture-plus-text or picture-plus-text-plus-signal. Immediately after experimental treatment, participants were administered tests of pictorial recall, matching, jigsaw puzzles, and retention as well as cognitive load measurement and attitude questionnaires. Experimental treatment was the independent variable, while the comprehension test, cognitive load questionnaire, and attitude questionnaire were the dependent variables. The results indicated that learners in the cueing condition outperform those in a non-cueing condition for matching and total score, but not for retention. The analysis of cognitive load revealed that learners in the cueing condition experience lower germane load than those in the non-cueing condition. However, the result of the questionnaires indicated that all the students felt mobile phones were convenient and useful in English learning regardless of the presence or not of attention cueing. The results stress the importance of presenting attention-capturing arrows in external representation as it can result in better learning efficiency.     

Child and Adolescent Predictors of Personality in Early Adulthood

This study investigated development of the Big Five personality traits from early childhood into adulthood. An initial group of 137 Swedish children were assessed eight times between ages 2 and 29 years. Initial decreases in extraversion leveled off in early adulthood; agreeableness and conscientiousness increased from ages 2 to 29; neuroticism initially increased, leveled off in later childhood and adolescence, and decreased throughout early adulthood; while openness to experience showed an initial increase, then decreased and leveled off in early adulthood. Individual developmental trajectories varied significantly, particularly in relation to gender. Personality traits became increasingly stable, and the fact that childhood scores predicted scores in adulthood indicated that personalities are fairly stable across this portion of the life span.

Relationship Reciprocation Modulates Resource Allocation in Adolescent Social Networks: Developmental Effects

Adolescence is characterized as a period of social reorientation toward peer relationships, entailing the emergence of sophisticated social abilities. Two studies (Study 1: N = 42, ages 13–17; Study 2: N = 81, ages 13–16) investigated age group differences in the impact of relationship reciprocation within school‐based social networks on an experimental measure of cooperation behavior. Results suggest development between mid‐ and late adolescence in the extent to which reciprocation of social ties predicted resource allocation. With increasing age group, investment decisions increasingly reflected the degree to which peers reciprocated feelings of friendship. This result may reflect social‐cognitive development, which could facilitate the ability to navigate an increasingly complex social world in adolescence and promote positive and enduring relationships into adulthood.
