表演式学习──表演理论对“最近发展区”的发展

美国当代心理学家、剧作家、表演理论的创始人弗雷德·纽曼（FredNewman）及其同事致力于在实践中发展维果茨基的理论,从表演的维度探讨了zpd的概念,并以此为核心提出了表演式学习的概念,以区别于在当今社会大行其道的工具性学习,即以获取知识和技能为目的的学习。表演理论通过对工具性学习的消极影响的批判及对表演式学习的倡导,在人的教育和发展方面提出了独到见解。     

学前数学教法和儿童智能发展的追踪研究

本研究从儿童心理发展的特点和数学学习之间的内在规律出发,综合考查了各类教学法在学前施教的利弊;同时,在活动教法、指导操作法、演示法和讲授法之间做了对比实验,并设计了一整套以指导操作法为主的学前数学教法,以演示为主的数学教法之间进行了长期、深人的跟踪对比实验。结果表明,在其他变量基本被控制的条件下,指导操作法优于其他的教法;实验班儿童的智能发展,特别是数学能力的发展,明显好于对照班的儿童。这个优势一直持续到小学毕业。

Greatness and misery in the teaching of the psychology of learning

Overshadowed by more popular disciplines, the study of learning seems to have lost its prominent place in the undergraduate psychology curriculum. In the first part of this essay, we argue that one reason for this state of affairs is the current content of psychology of learning courses, namely, its disproportionate emphasis on facts, procedures, and everyday examples at the expense of functional and conceptual investigations. In the second part of the essay, we outline an alternative approach to the teaching of learning, one that emphasizes basic contents such as the conceptualization of learning as a biological adaptation or the study of temporal regulation, critical methodological issues such as the logic of experimental designs or the difficulties of measuring behavior, and broad epistemological problems such as the role of hypothetical constructs, the advantages of quantitative reasoning, or the origins of knowledge and its integration. By using learning as a means towards more fundamental ends, the splendor of the discipline and its prominent place in the undergraduate curriculum may be restored.     

What Every Teacher of Science and Religion Needs to Know about Pedagogy

This essay provides practical tips for effective teaching in science-and-religion courses. It offers suggestions for dealing with difficult questions and creating a climate of shared learning. Along with pedagogical advice, it covers fundamental principles for teaching broadly integrative religion-and-science courses. Instructors are encouraged to reflect on their purpose(s) in offering their course and to formulate specific objectives using the techniques and resources outlined here.     

Developmental changes in associations between auditory-visual events

The goal of the present study was twofold: to examine the influence of two amodal properties, co-location and temporal synchrony, on infants' associating a sight with a sound, and to determine if the relative influence of these properties on crossmodal learning changes with age. During familiarization 2-, 4-, 6- and 8-month-olds were presented two toys and a sound, with sights and sounds varying with respect to co-location and temporal synchrony. Following each familiarization phase infants were given a paired preference test to assess their learning of sight-sound associations. Measures of preferential looking revealed age-related changes in the influence of co-location and temporal synchrony on infants' learning sight-sound associations. At all ages, infants could use temporal synchrony and co-location as a basis for associating an auditory with a visual event and, in the absence of temporal synchrony, co-location was sufficient to support crossmodal learning. However, when these cues conflicted there were developmental changes in the influence of these cues on infants' learning auditory-visual associations. At 2 and 4 months infants associated the sounds with the toy that moved in synchrony with the sound's rhythm despite extreme violation of co-location of this sight and sound. In contrast, 6- and 8-month-olds did not associate a specific toy with the sound when co-location and synchrony information conflicted. The findings highlight the unique and interactive effects of distinct amodal properties on infants' learning arbitrary crossmodal relations. Possible explanations for the age shift in performance are discussed.     

Posttraining Electrical Stimulation of Vagal Afferents with Concomitant Vagal Efferent Inactivation Enhances Memory Storage Processes in the Rat

Peripherally administered or released substances that modulate memory storage, but do not freely enter the brain, may produce their effects on memory by activating peripheral receptors that send messages centrally through the vagus nerve. Indeed, vagus nerve stimulation enhances memory performance, although it is unclear whether this effect is due to the activation of vagal afferents or efferents. To eliminate the possible influence of descending fibers on memory storage processes, rats were implanted with cuff electrode/catheter systems along the left cervical vagus. Forty-eight hours following surgery, each animal received a 3.0-μl infusion (1.0 μl/min) of either lidocaine hydrochloride (75.0 mM) or isotonic saline below the point of stimulation. Animals were then trained 10 min later on an inhibitory-avoidance task with a 0.75-mA, 1.0-s foot shock. Sham stimulation or vagus nerve stimulation (0.5-ms biphasic pulses; 20.0 Hz; 30 s; 0.2, 0.4, or 0.8 mA) was administered immediately after training. Memory, tested 24 h later, was enhanced by stimulation whether descending vagus nerve fibers were inactivated or not. Both lidocaine- and saline-infused groups showed an intensity-dependent, inverted-U-shaped pattern of retention performance, with the greatest effect observed for 0.4 mA (U= 9,p< .05, andU= 7,p< .01, respectively). Additionally, animals that received lidocaine infusions, but no vagus nerve stimulation, showed impaired memory compared to the performance of saline-infused control animals (U= 11,p< .05). Together, these findings suggest that vagal afferents carry messages about peripheral states that lead to the modulation of memory storage and that the memory-enhancing effect produced by vagus nerve stimulation is not mediated via the activation of vagal efferents.     

Physostigmine''s Impact on Brief Shock-Induced Hypoalgesia Parallels Its Effect on Memory

Past research indicates that the anticholinergic drug scopolamine disrupts memory and environmentally induced hypoalgesia in rats. The present study examined the impact of the centrally active cholinesterase inhibitor physostigmine, which enhances memory and central cholinergic activity, on brief shock-induced hypoalgesia on the tail-flick test using Sprague–Dawley rats. It is reported that physostigmine (0.1 mg/kg) potentiates the magnitude of this hypoalgesia. Contrary to past research, our results showed that omission of baseline testing did not eliminate hypoalgesia or its potentiation by physostigmine. Similar to its effects on memory, physostigmine (0.04, 0.1, and 0.25 mg/kg) has a nonmonotonic impact on brief shock-induced hypoalgesia; low doses potentiated hypoalgesia (0.1 mg/kg), whereas a high dose (0.25 mg/kg) disrupted it. These results provide further evidence that the cholinergic system indirectly affects pain reactivity by modulating the memory of the aversive event.     

Behavioral Family Interventions for Improving Child-rearing: A Review of the Literature for Clinicians and Policy Makers

This paper reviews evidence that behavioral family interventions are effective at improving child-rearing in distressed families and families with children exhibiting disruptive behavior. Essential therapeutic strategies offered within a collaborative therapeutic process are identified. Exemplary materials for parents and clinicians are identified. Differences between behavioral family interventions and two popular press parenting approaches are highlighted, including the lack of empirical support for these widely used programs and the advice they offer which runs counter to behavioral approaches. Recommendations are offered for combining behavioral family interventions with other empirically supported approaches, promoting more widespread use of empirically supported treatments, such as behavioral family interventions, and the need for a public health perspective on family functioning, involving collaboration among clinicians, policy makers, and researchers.
