Effects of environmental support on overt and covert visuospatial rehearsal

People can rehearse to-be-remembered locations either overtly, using eye movements, or covertly, using only shifts of spatial attention. The present study examined whether the effectiveness of these two strategies depends on environmental support for rehearsal. In Experiment 1, when environmental support (i.e., the array of possible locations) was present and participants could engage in overt rehearsal during retention intervals, longer intervals resulted in larger spans, whereas in Experiment 2, when support was present but participants could only engage in covert rehearsal, longer intervals resulted in smaller spans. When environmental support was absent, however, longer retention intervals resulted in smaller memory spans regardless of which rehearsal strategies were available. In Experiment 3, analyses of participants’ eye movements revealed that the presence of support increased participants’ fixations of to-be-remembered target locations more than fixations of non-targets, and that this was associated with better memory performance. Further, although the total time fixating targets increased, individual target fixations were actually briefer. Taken together, the present findings suggest that in the presence of environmental support, overt rehearsal is more effective than covert rehearsal at maintaining to-be-remembered locations in working memory, and that having more time for overt rehearsal can actually increase visuospatial memory spans.     

自然联结的概念、功能与促进

自然联结包含个体对人与自然一体化关系的认同,以及与自然之间的情感联结,反映了人与自然之间关系的质量。它与个体的身心健康、认知功能和环保态度及行为显著相关。根据对已有研究结果的分析,自然联结可能通过认知和情感两条路径形成和发展。未来研究需继续探讨自然联结的内涵和结构,深入研究其形成和发展的心理机制,以及在自然影响人过程中的作用。还可与教育实践相结合,进行系统的干预和追踪研究。此外,建议将这一概念引入心理学其他领域的研究,以获得更多理论与应用价值。     

时间参照对绿色消费的影响：环保意识和产品环境怀疑的调节作用

绿色消费虽然受到越来越多的关注,但消费者的绿色承诺很难转化为实际的购买行为,出现了消费者的不作为现象。本研究试图探讨时间参照对消费者不作为的影响以及环保意识是否能够有效抑制这种不作为。研究发现,消费者在近期情境下对绿色产品的购买意愿低于远期,出现了绿色消费不作为现象,即个体更倾向于在将来而不是现在购买绿色产品。尤为重要的是,环保意识对消费者不作为的弱化作用受制于个体的产品环境怀疑：产品坏境怀疑较低时环保意识的弱化作用明显,而产品环境怀疑较高时环保意识的弱化作用则不存在。     

Wild Things: Stories,Transition, and the Sacred in Ecological Social Movements

This article examines the role of stories in ecological activism. It first situates stories inside object ecologies, encompassing relationships of reliance, care, and maintenance of things. It suggests that ecologies of this sort work as an extended mind where our cognition takes place and meaning is apprehended, so that what we can think of is always a function of what we have “at hand.” The article then considers how these ecologies are impacted by discourses on climate change and peak oil, which stress the impossibility to keep ordering our lives through the same entanglements that have supported them so far. A dissonance arises between the sort of demands and dependencies we are still subject to on a daily basis and the anticipation that those demands and dependencies shall not be able to endure. Stories of transition, which tread a middle ground between denial and collapse hysteria, dissipate this tension. In so doing, they contribute to the growing of alternative sacred forms, working as attractors that constitute groups as moral collectives. These forms are woven through alternative entanglements of objects, bodies, and other stories, providing determinate implication for action, from the indeterminacy of the unknowns of climate change and peak oil.     

Sustainable Environmental Development: The Moderating Role of Environmental Identity

This study develops and tests a model of Chinese residents' evaluation of government developmental activities based on identity theory and social exchange theory. The study proposes hypotheses regarding the influences of perceived benefits and environmental identity on residents' satisfaction with the government, the moderating role of environmental identity in the relationship between perceived benefits and satisfaction, and the effect of satisfaction on residents' support intentions. The model is tested with data collected from 474 residents of four cities in China. Results show environmental identity, along with perceived economic and environmental benefits, plays a very important role in residents' satisfaction with the government. The significant moderating role of environmental identity suggests differential effects of perceived benefits on satisfaction are observed based on the level of environmental identity. Satisfaction is found to be important for obtaining residents' support for the government and future environmental development. Implications of the study are discussed.     

Dynamic multiple-objective optimization of environmental regulation policies

Environmental regulation policies are tested via alternative multi-objective criteria in order to test their efficiency when they are spread over time—that is in a dynamic setting. The implication is carried to the Haifa Bay area in Israel with an extension to the entire country. The results presented in this paper can give decision makers another perspective of their decisions. The implication of their choice on the state(s) of the system through time so they can test the efficiency criterion in each period of the planning horizon. © 1998 John Wiley & Sons, Ltd.     

Révision de la loi bioéthique : les dangers de l’autoconservation des ovocytes pour convenance personnelle

Legalization of self-conservation of ovocytes for personal convenience is considered by the second article of the bioethics legislative proposal, adopted by French National Assembly. This practice is aiming to allow men and women to keep their gametes for the purpose of a subsequent medically assisted procreation. Does this new liberty risks to take away a human's individual liberty and more specifically a women's one? Indeed, to legalize self-conservation of ovocytes for personal convenience means to extend the message whereby a woman could delay her maternity. The result would be an implicit pressure: as it becomes medically possible to privilege first of all a career and then to envisage maternity, woman seeking high performance must necessarily choose it. This technique could therefore hide a clear-cut decline for women's rights, again confronted with a cornelian choice, a family or a career.     

“美即好”？颜值对工作幸福感的“过不及”效应

本文基于资源保存理论,考察职场中颜值影响工作幸福感的机制及边界,对1079份配对数据的多项式层级回归分析发现：颜值对工作幸福感有倒U型的影响,颜值中等偏上（6.88）的员工有最强的工作幸福感;不同职场类型中颜值的影响效应存在差异,在高要求-高控制的职场中,颜值对工作幸福感的曲线效应最强;分配公平感在上述影响路径和交互效应起中介作用。结论对人力资源管理和面孔吸引力理论具有积极贡献。     

The effects of noncontingent access to single- versus multiple-stimulus sets on self-injurious behavior

The automatically reinforced self-injury of a girl with autism was treated by providing noncontingent access to a single set of preferred toys during 30-min sessions. The reductive effects of the intervention waned as the session progressed. Rotating toy sets after 10 min or providing access to multiple toy sets resulted in reductions that lasted the entire 30 min.     

Choice in a variable environment: every reinforcer counts

Six pigeons were trained in sessions composed of seven components, each arranged with a different concurrent-schedule reinforcer ratio. These components occurred in an irregular order with equal frequency, separated by 10-s blackouts. No signals differentiated the different reinforcer ratios. Conditions lasted 50 sessions, and data were collected from the last 35 sessions. In Part 1, the arranged overall reinforcer rate was 2.22 reinforcers per minute. Over conditions, number of reinforcers per component was varied from 4 to 12. In Part 2, the overall reinforcer rate was six per minute, with both 4 and 12 reinforcers per component. Within components, log response-allocation ratios adjusted rapidly as more reinforcers were delivered in the component, and the slope of the choice relation (sensitivity) leveled off at moderately high levels after only about eight reinforcers. When the carryover from previous components was taken into account, the number of reinforcers in the components appeared to have no systematic effect on the speed at which behavior changed after a component started. Consequently, sensitivity values at each reinforcer delivery were superimposable. However, adjustment to changing reinforcer ratios was faster, and reached greater sensitivity values, when overall reinforcer rate was higher. Within a component, each successive reinforcer from the same alternative ("confirming") had a smaller effect than the one before, but single reinforcers from the other alternative ("disconfirming") always had a large effect. Choice in the prior component carried over into the next component, and its effects could be discerned even after five or six reinforcement and nonreinforcement is suggested.
