Field and laboratory studies of littering

Four studies are reported. In the first, it was shown that littering rates vary substantially across areas of a large urban region and that the rate for a particular area is correlated with the amount of litter already present. It was also found that males litter more than females and young people more than old. In the second study, a laboratory experiment, a causal relationship between the amount of litter in an area and the likelihood it will be littered was demonstrated. A third study replicated this latter finding, but did not find a relationship between the amount of stress experienced by a subject and the likelihood that he or she would litter. In the fourth study, a field experiment, subjects who were approached and asked to sign a petition about clean streets littered less than control subjects.

Positive reinforcement of litter removal in the natural environment

Litter is an especially large and costly problem in unsupervised high-use recreational areas. This study investigated procedures to induce visitors to remove litter from an unsupervised U.S. Forest Service area in which signs attached to two litter stations instructed people to pick up and deposit litter. A small sum of money or chances on a larger sum given for participation usually resulted in more bags of litter being picked up per week. Although only a small proportion of the area's users participated in the project, ground surveys indicated the areas sampled were somewhat freer of litter during the payment condition. The results suggest that small monetary rewards may be a promising approach to litter control in unsupervised as well as supervised areas.     

Urban–rural differences in children's earliest memories

The purpose of the present study was to address the effects of urban vs. rural upbringing on earliest autobiographical memories. We asked children (aged 10–13) brought up in an urban vs. in a rural setting to report their earliest memories. Earliest memories of children from rural areas were a year later than those of children from urban areas. Moreover, memories of children from rural areas were more likely to contain social interactions and tended to be less detailed compared to those from urban areas. The groups, however, were not different in specificity, autonomous orientation, or emotion. Results are discussed in the context of a social cultural developmental approach.     

Individual Differences in Training Gains and Transfer Measures: An Investigation of Training Curves in Children with Attention‐Deficit/Hyperactivity Disorder

Currently, evidence for the beneficial effects of working memory (WM) training on transfer measures in children with attention‐deficit/hyperactivity disorder (ADHD) is inconsistent. Although there is accumulating evidence for the role of individual differences in training and transfer gains of cognitive training, this area has been left unexplored for children with ADHD. In the current study, an advanced latent growth curve model analysis was used to investigate the individual differences in learning curves (training gains) of WM training tasks within a new cognitive intervention ‘Paying Attention in Class’. It was investigated whether certain baseline variables (age, intelligence quotient, externalizing behaviour problems and presence of learning disability) predicted the learning curves and how these individual learning curves influenced near‐transfer and far‐transfer measures. A total of 164 children diagnosed with ADHD, between the age of 8 and 12 years old, followed this new Paying Attention in Class intervention. WM (near‐transfer) and academic performance (far‐transfer) measures were assessed before treatment and directly after treatment. Results showed that individual differences at the start of training were predicted by age and intelligence quotient, but the individual differences in learning curves were not predicted by any of the baseline variables. Both for the verbal and the visuospatial WM training, children with larger training gains (i.e. steeper training curves) showed larger benefits on the near untrained transfer measures. These effects were absent for the far‐transfer measures. Current study shows that training WM is quite complex and has its limitations for children with ADHD. Nonetheless, it highlights that training and transfer gains are affected by many different factors and warrants the need of a more in‐depth investigation of individual differences in future studies.Copyright © 2017 John Wiley & Sons, Ltd.     

Participatory planning and children's emotional labor in the production of urban nature

Children have increasingly been called upon to participate in the planning of their communities, especially in projects associated with urban nature and outdoor play spaces. Building upon the concept of emotional labor, we critically explore how children become enrolled in such initiatives. Specifically, we focus on the emotional geographies underlining children's participation, including the emotions children exhibit invest, experience and produce in these projects, as well as the ways these emotions are regulated, framed and used by urban managers and policy-makers in participatory planning activities. Our theoretical framework intersects research on emotional labor with recent geographic literature on children, urban governance, and emotions. We explore the idea of children's and young people's emotional labor through an analysis of a collaborative effort between local nonprofits, government agencies, youth organizations and research institutions aimed at addressing the lack of public green space in a disenfranchised urban community in California. The empirical evidence is drawn from a research project in which we engaged a group of 9–11 year old children in a variety of planning activities involving participatory mapping, use of visual media, and focus groups.     

幼儿心理压力的现状及与行为问题、家庭生态环境之间的关系

Implementation of an empirically based drug and violence prevention and intervention program in public school settings

Describes the implementation of a collaborative preventive intervention project (Healthy Schools) designed to reduce levels of bullying and related antisocial behaviors in children attending two urban middle schools serving primarily African American students. These schools have high rates of juvenile violence, as reflected by suspensions and expulsions for behavioral problems. Using a quasi-experimental design, empirically based drug and violence prevention programs, Bullying Prevention and Project ALERT, are being implemented at each middle school. In addition, an intensive evidence-based intervention, multisystemic therapy, is being used to target students at high risk of expulsion and court referral. Hence, the proposed project integrates both universal approaches to prevention and a model that focuses on indicated cases. Targeted outcomes, by which the effectiveness of this comprehensive school-based program will be measured, are reduced youth violence, reduced drug use, and improved psychosocial functioning of participating youth.     

An experimental analysis of anti-litter procedures

This study evaluates the differential effectiveness of six different anti-litter procedures in two neighborhood theaters. The procedures used to encourage individuals in attendance to pick up litter and deposit it properly included: providing litterbags, providing litterbags with instructions to use them, providing extra trash cans, showing a special anti-litter film before the feature film, and providing incentives for the appropriate deposit of litter. In both theaters, the incentive procedures resulted in the removal of over 90% of all litter by the children in attendance, a figure far above that achieved by the other procedures investigated.     

Social environment and reproduction in female European rabbits (Oryctolagus cuniculus): benefits of the presence of litter sisters

The authors investigated in an observational study the consequences of the presence of litter sisters on the social interactions and on reproductive performance of young female European rabbits (Oryctolagus cuniculus) from a population living under seminatural conditions. In early winter, when all young females were settled in a social group, they were characterized by the presence or absence of litter sisters in their groups. Females with litter sisters in their groups displayed significantly more positive social interaction with females of their social group compared to females without sisters, whereas this difference was mainly due to the high frequency of positive social interactions among the respective sisters. Such differences between the females of both categories were already apparent during the animals' juvenile phase, before the females integrated into a particular group: females which later had litter sisters in their group showed more positive social behavior than females which later no longer had litter sisters. During their first breeding season, females with litter sisters present generally started to breed earlier by an average of 14 days. A more favorable social environment might have possibly facilitated the earlier onset of breeding in females with present litter sisters by attenuating the negative consequences of stress.     

Les troubles du comportement chez l'enfant et l'adolescent : vers une cohérence des pratiques pluridisciplinaires

Many professionals are involved with the children who present behaviour disorders. One question is “How to develop a medical and psychological care project which involves the child, the family and the school”. In order to respond to that question, four papers with different theoretical approaches will follow in this issue of Pratiques Psychologiques. They present: 1) the different nosological status of behaviour disorders; 2) an example of an analytic work with children and their relatives; 3) a behavioural intervention at school; 4) the problems of treatment access and possibilities of new responses.     

Human-centeredness is not a universal feature of young children's reasoning: Culture and experience matter when reasoning about biological entities

We consider young children's construals of biological phenomena and the forces that shape them, using Carey's (1985) category-based induction task that demonstrated anthropocentric reasoning in young urban children. Follow-up studies (including our own) have questioned the generality of her results, but they have employed quite different procedures and either have not included urban children or, when urban samples were included, have failed to reproduce her original findings. In the present study of 4–10-year-olds from three cultural communities, our procedures followed Carey's more closely and replicated her findings with young urban children. However, they yielded quite different results for young rural European American and young rural Native American children. These results underscore the importance of a complex interaction of culture and experience – including both day-to-day interactions with the natural world and sensitivity to the belief systems of the communities – in children's reasoning about the natural world.     

Environmental Effects on Outdoor Social Behavior in a Low-Income Urban Neighborhood: A Naturalistic Investigation1

Outdoor behavior was measured and compared using a behavioral mapping procedure across three contrasting environments in a low-income urban neighborhood. The environments were an old ghetto neighborhood of low-rise tenement houses, a traditional high-rise housing project, and an innovative high-rise housing project, where a creative outdoor design had been added to encourage outdoor use. As predicted, the old neighborhood and the innovative project showed higher levels of outdoor socializing than did the traditional project. Unexpectedly, the old neighborhood showed the highest level of task-oriented activity relative to recreation and leisure. Several propositions concerning the relationship between behavior and urban environment are considered, and a number of implications for urban design are advanced.     

Glucocorticoid response to changes in enclosure size and human proximity in the Persian onager (Equus hemionus onager)

This study investigated glucocorticoid (GC) responses to season and changes in enclosure size and human proximity in the Persian onager (Equus hemionus onager). Enzyme immunoassays were validated to measure GC metabolites in urine and feces (fGCM). Fecal samples were collected from 10 female onagers while in a large pasture, after transport to smaller yards (in greater proximity to people), and 2 months thereafter. Urine samples were collected for 1 year while females were in smaller yards to examine seasonal GC activity. Approximately, 2-fold increases (P < 0.05) were observed in fGCM levels after transport from pasture to yards with increased human exposure, followed by a rapid decline (within -17 days) to baseline (pasture) values. However, responses varied among onagers during the 30 days after translocation, with one female failing to acclimate. Mean fGCM concentrations in smaller yards 2 months after transport were comparable to those in pasture. Seasonal GC concentrations were lowest (P < 0.05) during winter, indicating modest seasonal variability. Results demonstrate an acute increase in GC secretion in Persian onagers that moved from large to small enclosures coincident with increased human activities. Most animals acclimated within 3 weeks, suggesting that this rare equid has retained mechanisms to acclimate to marked alterations in an ex situ environment.     

Children’s Play with a Forest Diorama as a Window into Ecological Cognition

This study examined the play of 4-year-old children with a forest diorama that included toy representations of plants and animals. To examine the potential role of culture and expertise in diorama play, children from 3 samples participated: rural Native American, urban Native American, and urban non-Native American. Children’s playtime was divided into time segments, which were coded for types of actions and for types of talk. Children from all 3 samples actively engaged with the diorama in both realistic and imaginative play. Furthermore, children from all samples were sensitive to ecological relations. In addition, Native American children talked at least as much as the non-Native American children, a finding that challenges widespread characterizations of Native American children as less talkative and possessing smaller vocabularies. The most striking finding was that Native American children (both urban and rural) were more than twice as likely as non-Native American children to take the perspective of an animal in their play. These results demonstrate the value of dioramas for assessing young children’s biological cognition.     

母子关系、师幼关系与学前流动儿童的社会适应行为

母子关系和师幼关系是儿童早期发展中最重要的人际关系, 在儿童社会适应中扮演着重要的角色。研究以北京市271名学前流动儿童和552名学前城市儿童为被试, 采用问卷法考察母子关系、师幼关系与学前流动儿童的社会技能、外显和内隐问题行为之间的关系。结果发现:(1)流动儿童母子关系亲密程度低于城市儿童, 母子关系冲突性、师幼关系亲密性和冲突性与城市儿童没有差异;(2)母子关系对儿童社会适应行为的预测作用在流动儿童和城市儿童上没有显著差异, 母子关系亲密性正向预测社会技能, 负向预测内隐问题行为;母子关系冲突性负向预测社会技能, 正向预测外显和内隐问题行为;师幼关系亲密性正向预测城市和流动儿童的社会技能, 并且显著负向预测流动儿童的内隐问题行为;(3)师幼关系对母子关系的调节作用主要表现在流动儿童而非城市儿童上, 师幼关系低冲突能够减少母子关系冲突性对流动儿童社会技能的负向预测作用, 师幼关系高亲密能够减少母子关系冲突性对流动儿童内隐问题行为的正向预测作用。     

The effect of items in working memory on the deployment of attention and the eyes during visual search

Paying attention to an object facilitates its storage in working memory. The authors investigate whether the opposite is also true: whether items in working memory influence the deployment of attention. Participants performed a search for a prespecified target while they held another item in working memory. In some trials this memory item was present in the search display as a distractor. Such a distractor has no effect on search time if the search target is in the display. In that case, the item in working memory is unlikely to be selected as a target for an eye movement, and if the eyes do land on it, fixation duration is short. In the absence of the target, however, there is a small but significant effect of the memory item on search time. The authors conclude that the target for visual search has a special status in working memory that allows it to guide attention. Guidance of attention by other items in working memory is much weaker and can be observed only if the search target is not present in the display.     

幼儿汉语口语感知特点及神经机制

口语感知是当前心理语言学的研究热点, 然而以往研究大多以婴儿和成人为被试, 缺乏对幼儿口语感知的研究。此外, 现有口语感知模型主要是基于非声调语言研究建立起来的, 对汉语并不完全适用。汉语是一种声调语言, 在语音构成上不同于非声调语言。本项目将立足于汉语口语特点, 以3~5岁幼儿为研究对象, 考察幼儿汉语口语感知特点及神经机制。综合使用眼动方法、ERP方法和LORETA源定位技术探讨以下问题：(1)幼儿在前注意阶段和注意阶段的听觉语音辨别特点; (2)幼儿汉语口语词汇识别过程中音段信息和超音段信息的作用; (3)幼儿汉语口语感知的神经机制。本项目研究结果将揭示幼儿汉语口语感知特点, 为完善现有的口语感知模型提供新的实验证据。     

Urban cyberspace policy initiatives in Manchester,UK, 1989–1999

As the world is becoming both digital and urban, cyberspace advancements pose a serious challenge to the study of modern cities’ development. This research work stresses the importance of investigating the intervention and effectiveness of public policies and agencies that involve the development of the cyberspace in urban restructuring. Thus, the present paper reviews and analyzes the deployment of urban cyberspace policy initiatives in Manchester, during the 1989–1999 decade, reflecting critically upon the questions raised from the literature regarding the cyberspace paradigm in urban policy and planning. Vassilys Fourkas graduated in Civil Engineering from the Aristotle University of Thessalonica in 1993 and he then followed a post-graduate research program in the area of computer-simulation techniques in urban planning, at the University of Venice-Dept. of Architecture-DAEST/Italy. He is currently working at the Egnatia Odos SA, as the Head of the Observatory Unit which is concerned with the measurement, evaluation and study of spatial impacts caused by the Egnatia motorway (a TEN, EU-funded project). His academic and research interest focuses on the issues of virtual geography, urban cyberspace planning and virtual cities in relation to modern urban regeneration strategies and plans in European Union. In September 2003 he received a post-doctorate grant from the Greek government (Greek State Scholarship Foundation) to carry out a research project regarding the development of Greek cities over cyberspace.
