A diagnostic approach to increase reusable dinnerware selection in a cafeteria

The current project tested a diagnostic approach to selecting interventions to increase patron selection of reusable dinnerware in a cafeteria. An assessment survey, completed by a sample of 43 patrons, suggested that the primary causes of wasteful behavior were (a) environmental arrangement of dinnerware options and (b) competing motivational variables. A functional relation between environmental arrangement and reusable product selection was demonstrated in a reversal design. However, the largest effect occurred as function of a multicomponent intervention involving environmental arrangement, employee involvement, and personal spoken prompts with motivational signs. The results support the use of informant assessments when designing community interventions.     

自我参照和环境参照整合过程中的主方位判断

通过三个实验证明,自我参照和环境参照转化与整合过程中的主方位判断受拍摄方向和目标位置的影响。二者对主方位判断的作用模式不会随主方位判断任务的改变而改变,拍摄方向效表现为：朝北效应（匹配效应）和主方位效应,体现的是自我参照和环境参照整合过程中环境参照对主方位的影响;目标位置效应的认知加工时间模式可表示为：前-后轴<左-右轴<其他位置,体现的是自我参照和环境参照整合过程中自我参照对主方位的影响。本文以规范轴和规范方向为框架对数据结果进行了分析和解释。     

BIRDS, BARBOUR, AND BOATS

Abstract. Ian Barbour in the second volume of his Gifford Lectures makes a significant contribution to environmental ethics. Worthy of scrutiny are his views on the relation of technology to the environment, on the distinction between nature and culture, on the problem of hierarchical thinking, and on the notion of sustainability. His integrated approach is a model for how we must relate to nature.     

Control of responding by sounds of different quality: an evolutionary analysis.

Two experiments investigated the acquisition of discriminations between two acoustic stimuli of different quality (noise bursts vs. a 2-kHz pulsed signal) when features of the everyday environment were incorporated into the experiments. In Experiment 1, rats were trained, using food, to press a lever. Throughout all sessions, 5-s trials of noise bursts (the random stimulus) were presented, after variable intertrial intervals, through a remote speaker mounted outside the experimental enclosure. The noise burst occurred randomly with respect to reinforcement of lever pressing and had no programmed relationship to the animal's behavior. When lever pressing was established, the 2-kHz signal was presented through a speaker adjacent to the response lever according to a different set of variable intertrial intervals. A response in the presence of the 2-kHz signal terminated the trial and was reinforced. The 2-kHz signal acquired control of responding within the first few trials, whereas the random stimulus exerted no control of responding. In Experiment 2, rats were trained to press the lever in the presence of the 2-kHz signal presented through the adjacent speaker on a variable intertrial interval. After 14 sessions, 5-s trials of noise bursts (random stimulus) were presented through the remote speaker on the second variable intertrial interval. The random stimulus initially elicited exploratory behavior, which then rapidly declined. Subsequently, the random stimulus exerted no or weak control of responding. The introduction of the random stimulus had no effect on responding in the presence of the adjacent stimulus. In Experiments 3 and 4 the random stimulus was presented through the adjacent speaker, and the stimulus correlated with reinforcement was presented through the remote speaker. In both experiments, there was persistent control of responding by the random stimulus and slow development of control by the stimulus correlated with reinforcement. In Experiment 5, both stimuli were presented through the adjacent speaker. There was persistent control of responding by the random stimulus.     

THE USE OF STIMULUS CONTROL OVER LITTERING IN A NATURAL SETTING

A conventional litter receptacle (55-gallon drum) and a specially designed receptacle consisting of a 55-gallon drum adorned with a plywood “hat” were alternated in two areas of a football stadium over a period of four games. A frequency count of several types of litter articles showed that more than twice as many items were deposited within the experimental container than the conventional one (an average of 52.5 and 21.5 items per game, respectively). The weight of litter deposited within each container showed a similar relationship. An average of 0.65 kg of litter per game were deposited within the conventional receptacle compared with an average of 1.3 kg per game for the experimental receptacle.     

Infant state in relation to its environmental context

Two neonatal intensive care units (NICU) were observed every 15 minutes for at least 72 consecutive hours. Although infants on both NICUs were exposed to considerable amounts of stimulation, there were differences between the units for each environmental measure in the amount of stimulation and/or the pattern of circadian periodicity. The two NICUs also differed in the amount of time infants spent in various states and in the pattern of state periodicity. In general, the diurnal rhythms of the infant states were associated with the diurnal rhythms of different environmental events; furthermore, the patterns of association were not the same on the two NICUs. The results point to potential problems in depicting a “typical” NICU. More importantly, they suggest that the environmental of NICUs has a recognizable influence on aspects of their inhabitants' behavior and that the nature of influence is different from NICU to NICU. The effects are potentially significant for physical, social, and cognitive development.     

Rolston, Lonergan, and the Intrinsic Value of Nature

In recent metaethical debate over ways to justify the notion of intrinsic natural value, some neopragmatists have challenged realist conceptions of scientific and moral truth. Holmes Rolston defends a critical-realist epistemology as the basis for a metaphysics of projective nature and a cosmological narrative—both of which set up a historical ontology of objective natural value. Pure ecological science informs the wilderness experience of Rolston's ideal epistemic subject, the sensitive naturalist. The author argues that Rolston's account of the relation between knowing and valuing can be clarified and strengthened by appropriating Bernard Lonergan's transcendental method. Conversely, Lonergan's view of moral self-transcendence can be developed further in light of Rolston's virtue epistemology, which is embodied in the figure of the sensitive naturalist.     

Distress Tolerance and Rational-Emotive Behavior Therapy: A New Role for Behavioral Analogue Tasks

Rational-emotive behavior therapy (REBT) is a widely utilized treatment approach for many mental disorders, but it has been “relatively neglected in the professional scientific literature” (Ellis 2003b). This neglect has been attributed in part to a lack of solid REBT outcome studies, which in turn stems from the difficulty of measuring constructs of interest in REBT, such as irrational beliefs, via self-report measures. In light of these concerns, the current paper aims to identify the potential utility of behavioral analogue laboratory tasks for advancing the understanding of mechanisms in REBT, as well as treatment outcome using this therapeutic approach. Specifically, we focus on the utilization of behavioral measures of distress tolerance and their application to the key REBT construct of frustration intolerance. In identifying the parallels across distress tolerance and frustration intolerance, we consider how the incorporation of distress tolerance tasks into REBT research can be useful in evaluating the role of frustration intolerance in the initiation, maintenance, and treatment of disordered behavior across a broad range of clinical disorders.
