学习不良儿童的家庭心理环境,父母教养方式及其与社会性发展的关系

从２３０８名１０—１５岁儿童中选取４２９名被试的研究结果表明．一般儿童的家庭心理环境、父母教养方式大大优于学习不良儿童,这些家庭资源与学习不良儿童的社会交往、自我概念和社会行为等有着密切的联系,说明家庭心理环境、父母教养方式对学习不良儿童社会性发展产生着重要作用。     

From gains to losses: Age-related differences in decisions under risk in a non-monetary gambling task

Lifespan theory suggests a shift from a primary orientation towards attaining gains in young adulthood to preventing losses in older adulthood. The current research tested if this motivational shift is reflected in behavioural and emotional responses to risks in non-monetary gains and losses. Study 1 established in a sample of N = 168 younger (18–30 years) and older adults (65–79 years) that a non-monetary gambling task was experienced similarly by the age groups with respect to arousal and valence of the task, and the willingness to continue playing. In Study 2 (N = 83), differences between young (18–30 years) and older (64–85 years) adults’ risk-taking in this non-monetary gambling task with mixed gambles were tested while assessing physiological responses (event-related heart rate change) to gain and loss feedback. Behavioural – but not physiological – results confirm hypotheses derived from a lifespan motivational framework regarding age-differential effects of gains and losses.     

Onset Neighborhood Density Slows Lexical Access in High Vocabulary 30-Month Olds

There is consensus that the adult lexicon exhibits lexical competition. In particular, substantial evidence demonstrates that words with more phonologically similar neighbors are recognized less efficiently than words with fewer neighbors. How and when these effects emerge in the child's lexicon is less clear. In the current paper, we build on previous research by testing whether phonological onset density slows lexical access in a large sample of 100 English-acquiring 30-month-olds. The children participated in a visual world looking-while-listening task, in which their attention was directed to one of two objects on a computer screen while their eye movements were recorded. We found moderate evidence of inhibitory effects of onset neighborhood density on lexical access and clear evidence for an interaction between onset neighborhood density and vocabulary, with larger effects of onset neighborhood density for children with larger vocabularies. Results suggest the lexicons of 30-month-olds exhibit lexical-level competition, with competition increasing with vocabulary size.     

Factors influencing career maturity in the South African National Defence Force: A diagnostic approach

This study investigated factors influencing the career maturity of young members of the South African National Defence Force (SANDF). A sample of 310 young SANDF members (females=35%, blacks=90%) completed the following measures: career maturity inventory-revised, the career decision self-efficacy scale, the military hardiness scale, and the seven habits profile. They also completed a biographical information form. Data were analysed using multiple regression to predict career maturity from career decision self-efficacy, self-appraisal, occupational information, goal selection, planning, problem solving, hardiness, control, challenge, commitment, conscientiousness, life balance, pro-active behaviour, life goals, self-management, mutual-benefit thinking, listening, teamwork, continuous improvement and life skills. Findings suggest self-efficacy, occupational information, self-appraisal, commitment, challenge, emotional intelligence and continuous improvement have the strongest influence on career maturity. The results indicated that self-efficacy, life skills and personal drive empower young members to seek employment.     

Changes in optimism and pessimism in response to life events: Evidence from three large panel studies

Although individuals vary in how optimistic they are about the future, one assumption that researchers make is that optimism is sensitive to changes in life events and circumstances. We examined how optimism and pessimism changed across the lifespan and in response to life events in three large panel studies (combined N = 74,886). In the American and Dutch samples, we found that optimism increased across younger adulthood, plateaued in midlife, and then decreased in older adulthood. In the German sample, there were inconsistent results with respect to age differences and mean level changes in optimism. Associations between life events and changes in optimism/pessimism were inconsistent across samples. We discuss our results in the context of life events and lifespan development.     

Prolonged touch screen device usage is associated with emotional and behavioral problems,but not language delay,in toddlers

BackgroundTouch screen devices are now ubiquitous, and their usage by young children is increasing. However, the effects of these devices on young children are still unknown. Therefore, this study aimed to address the associations of touch screen device exposure with symptomatic emotional and behavioral problems and language development in children between the ages of 18 and 36 months.MethodA total of 161 primary caregivers of children between the ages of 18 and 36 months were recruited from the pediatric ward and outpatient clinic at a medical center in southern Taiwan. All caregivers were asked to fill out the Child Behavior Checklist for Ages 1½–5 (CBCL 1½–5) and a questionnaire on basic personal information and touch screen device usage, and they were also interviewed with the Communication and Language Screening Test for Birth to Three Chinese-Speaking Infant-Toddlers (CLST). Independent t-test and one-way ANOVA were used to examine the differences among the categories in the demographic variables and to characterize the touch screen device usage behaviors. Pearson’s correlation was used to analyze the relationship between language delay and the extent of touch screen device exposure. After primary univariate analysis, we used multiple regression models to examine the relationships among the effects of touch screen device usage behaviors on children's emotional and behavioral problems and language development.ResultThe children’s mean age was 25.63 months (SD = 5.35). Children who spent more time on touch screen devices were more likely to have emotional problems (β = .219, p < .010, 95 % CI: .279–1.518), anxious/depressive symptoms (β = .206, p < .050, 95 % CI: .170–1.244), somatic complaints (β = .291, p < .001, 95% CI: .455–1.462), social withdrawal symptoms (β = .194, p < .050, 95 % CI: 0.133–1.150), attention problems (β = .300, p < .001, 95 % CI: .432–1.267), and aggressive behaviors (β = .247, p < .010, 95 % CI: .967–3.983). The effects were not noted on language development (β = −.136, p < .100, 95 % CI: −2.595–.147).ConclusionYoung children who spent more time on touch screen devices were more likely to have emotional problems, anxious/depressive symptoms, somatic complaints, social withdrawal symptoms, attention problems, and aggressive behaviors, but not language delay.
