Age-related differences in idea generation and selection for propositional language

Conceptual preparation mechanisms such as novel idea generation and selection from amongst competing alternatives are critical for language production and may contribute to age-related language deficits. This study investigated whether older adults show diminished idea generation and selection abilities, compared to younger adults. Twenty younger (18–35 years) and 20 older (60–80 years) adults completed two novel experimental tasks, an idea generation task and a selection task. Older participants were slower than younger participants overall on both tasks. Importantly, this difference was more pronounced for task conditions with greater demands on generation and selection. Older adults were also significantly reduced on a semantic, but not phonemic, word fluency task. Overall, the older group showed evidence of age-related decline specific to idea generation and selection ability. This has implications for the message formulation stage of propositional language decline in normal aging.

助推目标实现：时间标记的动力效应

时间标记是指日常生活中所有突出的独特性事件。个体在经历当下的时间标记或期待未来的时间标记时, 其追求目标的动机水平得到提高, 并表现出更多的目标相关行为, 即时间标记具有一种动力效应。时间标记可能增加了个体对不同时间自我之间的分离感, 继而通过自我效能感、保持一致的自我形象、损失规避及缩小差距等心理过程提高追求目标的动机。未来研究应进一步探讨时间标记在动力效应中的角色定位及动力效应的持续时间、探究时间标记动力效应的普适性、检验可能的心理机制并在实践领域开展时间标记助推行为决策的应用研究。     

主动性人格与员工行为的关系：政治技能视角下有中介的调节模型

本研究通过两时点纵向问卷调查,探讨主动性人格与组织公民行为、任务绩效之间的关系,考察主动社会化行为在其中的中介作用,以及政治技能的调节作用。结果表明：（1）主动社会化行为在主动性人格和组织公民行为、任务绩效之间起中介作用;（2）政治技能对主动社会化行为在主动性人格和组织公民行为、任务绩效之间的中介效应起调节作用：当政治技能水平上升,主动性人格通过主动社会化行为对组织公民行为及任务绩效的预测更加明显。     

Impulsivity and Behavior-Dependent Life Events Mediate the Relationship of Reward Sensitivity and Depression,but Not Hypomania,Among at-Risk Adolescents

Both reward sensitivity and impulsivity are related to the development and course of bipolar spectrum disorders (BSDs) and have been implicated in other disorders and negative functional outcomes such as substance abuse, obesity, suicidal behaviors, and risk-taking. Furthermore, according to the transactional component of the Behavioral Approach System (BAS)/reward hypersensitivity theory of BSDs, people with reward hypersensitivity should experience more BAS-relevant events, and thus, are more vulnerable to mood symptoms and episodes via stress generation. Impulsivity may exacerbate stress generation in individuals at risk for BSDs based on exhibiting reward hypersensitivity. The current study examined whether impulsivity explained the generation of stress and subsequent mood symptoms beyond what is explained by reward sensitivity alone. Participants were 131 Moderate BAS and 216 High BAS sensitivity adolescents (M = 18.43 years, SD = 1.40), who completed baseline measures of reward sensitivity and impulsivity, as well as follow-up measures of life events and mood symptoms. Results from linear regression analyses indicated that higher baseline impulsivity predicted behavior-dependent, but not behavior-independent, life events. Furthermore, path analyses suggested that the effect of BAS group on depression symptoms at next follow-up was partly explained via the indirect effect of impulsivity and negative behavior-dependent life events. We did not find these effects for behavior-independent or positive-dependent events or for prediction of hypomanic symptoms. The findings suggest that impulsivity may account for stress generation of negative events that precede depression.     

The Facilitative Effects of Ambiguous Figures on Creative Solution

Empirical studies of creativity emphasize the importance of ambiguity advantage in idea generation and creative problem‐solving. This study examined whether ambiguous figures could directly induce a mind‐set that would transfer to the creative problem‐solving. In Experiment 1, we examined whether presentation of ambiguous figures would influence participants' performance in alternative uses tasks, and the results showed that prior exposure to ambiguous figures significantly enhanced participants' performance in the dimension of fluency, flexibility, and originality than those exposed to non‐ambiguous figures; in general uses tasks, there were no significant difference in the reaction time and originality between the ambiguous figure condition and non‐ambiguous figure condition. In Experiment 2, the facilitative effect of ambiguous figures on creative thinking was further examined with creative story generation tasks that demand more mental effort and increased cognitive load. Results showed that creativity of stories generated in ambiguous figure condition was scored significantly higher than those in non‐ambiguous figure condition. The current research extends our understanding of the facilitative effect of ambiguous figures on creative problem‐solving.     

Two types of serial dependence in visual working memory

Stimulus representations in working memory depend on memory traces of past stimuli both from previous trials and from the current trial. However, it is unclear whether the same or different mechanisms underlie this serial dependence across and within trials. We directly contrasted estimates of bias for pairs of immediately successive stimuli across and within trials. In each trial, participants memorized two consecutive motion direction stimuli (S1 and S2) and after a short delay were cued to report one of them. We found serial dependence across trials: The current S1 was attracted towards the preceding S2 when the latter had been cued for report. In contrast, within the same trial S2 was repulsed from S1. In addition, repulsion within a trial occurred for a broader range of motion direction differences between stimuli than attraction across trials. A second experiment in which 25% of trials did not require a response demonstrated that across‐trial attraction did not depend on whether the previous S2 actually had to be reported. Our findings provide evidence for two types of serial dependence operating across and within trials. They support the notion of different mechanisms integrating or segregating current from similar past memory contents depending on their task relevance.     

A Community's Response to Adverse Childhood Experiences: Building a Resilient,Trauma‐Informed Community

Adverse childhood experiences, or ACEs, may be mitigated by trauma‐informed social environments—programs, services, systems, communities—that offer responses to trauma that promote healing, recovery, and resilience. However, there is currently little empirical evidence to support the use of specific approaches to do so. Guided by a population health perspective, this paper describes a participatory community change process in response to ACEs that seeks to build a resilient, trauma‐informed community in Pottstown, PA. We examine the initial implementation phase of this change process, centered originally on the education sector and the social and behavioral health services sector, and then eventually expanding to 14 community sectors across two years. A variety of data sources and methods are used to track individual and organizational processes, as well as service system network processes. A central feature of this research is the use of data to generate hypotheses rather than test them. Data were also used to guide understanding and decision‐making during implementation. The results show that moving forward the community is well‐positioned to establish stronger inter‐agency and system supports for trauma‐informed practice in the service system and in the broader community. We discuss results for their implications for building resilient, trauma‐informed communities.     

‘Where are you from?’ Identity as a key to parenting by 1.5 generation Korean-New Zealand migrants and implications for counselling

In a qualitative study of the experiences of 1.5 generation Korean New Zealanders as parents, a notable finding was the significant part the participants’ identity-related experiences as migrants played in shaping their parenting practices. Interviews were conducted with 18 Korean “Kiwis” (New Zealanders), colloquially referred to as “Kowis,” who had arrived in New Zealand before 2002 as children or adolescents with their parents and were now married with children. Reflecting on the challenges of their migration and identity journeys enabled them to recognise their vulnerabilities and their advantages, and the multiple ways in which identity-related cultural conflicts and confusion influenced their parenting of their children. The implications are identified for further research and for counselling practice.
