Older (but not younger) preschoolers understand that knowledge differs between people and across time

We examined 3‐ to 5‐year‐olds' understanding of general knowledge (e.g., knowing that clocks tell time) by investigating whether (1) they recognize that their own general knowledge has changed over time (i.e., they knew less as babies than they know now), and (2) such intraindividual knowledge differences are easier/harder to understand than interindividual differences (i.e., Do preschoolers understand that a baby knows less than they do?). Forty‐eight 3‐ to 5‐year‐olds answered questions about their current general knowledge (‘self‐now’), the general knowledge of a 6‐month‐old (‘baby‐now’), and their own general knowledge at 6 months (‘self‐past’). All age groups were significantly above chance on the self‐now questions, but only 5‐year‐olds were significantly above chance on the self‐past and baby‐now questions. Moreover, children's performance on the baby‐now and self‐past questions did not differ. Our findings suggest that younger preschoolers do not fully appreciate that their past knowledge differs from their current knowledge, and that others may have less knowledge than they do. We situate these findings within the research on knowledge understanding, more specifically, and cognitive development, more broadly.     

Comparing Multiple Paths to Mastery: What is Learned?

Contemporary theories of learning postulate one or at most a small number of different learning mechanisms. However, people are capable of mastering a given task through qualitatively different learning paths such as learning by instruction and learning by doing. We hypothesize that the knowledge acquired through such alternative paths differs with respect to the level of abstraction and the balance between declarative and procedural knowledge. In a laboratory experiment we investigated what was learned about patterned letter sequences via either direct instruction in the relevant patterns or practice in solving letter-sequence extrapolation problems. Results showed that both types of learning led to mastery of the target task as measured by accuracy performance. However, behavioral differences emerged in how participants applied their knowledge. Participants given instruction showed more variability in the types of strategies they used to articulate their knowledge as well as longer solution times for generating the action implications of that knowledge as compared to the participants given practice. Results are discussed regarding the implications for transfer, generalization, and procedural application. Learning theories that claim generality should be tested against cross-scenario phenomena, not just parametric variations of a single learning scenario.     

计算难度和知识背景对消费者百分数基数忽略的影响

在选择促销品时,消费者经常会出现百分数基数忽略错误,即价值判断时只基于百分数大小而忽略基数。本研究以150名大学生为被试,考察计算难度和知识背景对百分数基数忽略的影响。结果表明:仅了解百分数基数忽略现象的消费者无论计算难度高低均会出现百分数基数忽略错误;而了解促销计算原理的消费者在高难度下会出现这种错误,在低难度下则不会,且了解促销原理有助于减轻消费者在高难度下出现该错误的倾向。     

On the psychological reality of a natural rule of syllable structure

If natural rules in phonology, such as the rule which deletes a word final consonant before a consonant, are frequently found in unrelated languages, it must be because they tap universal features of production and/or perception. The present experiment employed a learning task to see whether naive subjects have a predisposition for the natural rule as opposed to its converse (consonant deletion before a vowel). The Ss first learned four novel words (nouns) - two beginning with a consonant, two with a vowel - as paired associates to English ‘translations’. Then three novel adjectives were combined with each of the four nouns, following the natural rule for one group of Ss, the unnatural rule for the other. The twelve phrases were cued by their English translations and the S had to respond to each with the phonologically correct sequence of adjective and noun; confirmation followed each response. The Ss learning the unnatural corpus had a strong tendency to give natural responses, whereas the converse was not true. Consequently they made many more errors en route to mastery than their natural counterparts, even when the operative rule was displayed on the first trial by presenting in turn each adjective with its four following nouns. It appears that our Ss had implicit knowledge of the natural rule, even though it does not operate to any significant extent in English.     

学前儿童对“知道”和“会”的认知

72名3至5岁儿童接受了陈述性知识和程序性知识的学习任务,探查他们在获得新知识前后对自己是否“知道”和 “会”的认知和知识获取方式的认知 。结果显示,有部分学前儿童在不知道或不会的情况下报告自己“知道”或“会”,对自己的判断倾向于作出肯定回答;在学习新知识之后,学前儿童对自己是否“知道”的认识要比是否“会”的认知准确;儿童对陈述性知识的获取方式的认识好于程序性知识,3岁儿童对知识获取方式的认识存在困难。     

Dyslexia,authorial identity,and approaches to learning and writing: A mixed methods study

Background. Dyslexia may lead to difficulties with academic writing as well as reading. The authorial identity approach aims to help students improve their academic writing and avoid unintentional plagiarism, and could help to understand dyslexic students’ approaches to writing. Aims. (1) To compare dyslexic and non‐dyslexic students’ authorial identity and approaches to learning and writing; (2) to compare correlations between approaches to writing and approaches to learning among dyslexic and non‐dyslexic students; (3) to explore dyslexic students’ understandings of authorship and beliefs about dyslexia, writing and plagiarism. Sample. Dyslexic (n= 31) and non‐dyslexic (n= 31) university students. Method. Questionnaire measures of self‐rated confidence in writing, understanding of authorship, knowledge to avoid plagiarism, and top‐down, bottom‐up and pragmatic approaches to writing (Student Authorship Questionnaire; SAQ), and deep, surface and strategic approaches to learning (Approaches and Study Skills Inventory for Students; ASSIST), plus qualitative interviews with dyslexic students with high and low SAQ scores. Results. Dyslexic students scored lower for confidence in writing, understanding authorship, and strategic approaches to learning, and higher for surface approaches to learning. Correlations among SAQ and ASSIST scores were larger and more frequently significant among non‐dyslexic students. Self‐rated knowledge to avoid plagiarism was associated with a top‐down approach to writing among dyslexic students and with a bottom‐up approach to writing among non‐dyslexic students. All the dyslexic students interviewed described how dyslexia made writing more difficult and reduced their confidence in academic writing, but they had varying views about whether dyslexia increased the risk of plagiarism. Conclusions. Dyslexic students have less strong authorial identities, and less congruent approaches to learning and writing. Knowledge to avoid plagiarism may be more salient for dyslexic students, who may benefit from specific interventions to increase confidence in writing and understanding of authorship. Further research could investigate how dyslexic students develop approaches to academic writing, and how that could be affected by perceived knowledge to avoid plagiarism.     

情绪确定性对学习判断的影响

为了揭示情绪的确定性维度对学习判断的影响,本研究通过使用即时学习判断范式的两个实验,分别探讨了高确定性情绪(愤怒、快乐)和低确定性情绪(恐惧、惊喜)的被试在学习判断中的表现。结果显示:(1)愤怒组和快乐组花费在项目学习上的时间显著少于恐惧组和惊喜组;(2)愤怒组的学习判断值显著高于恐惧组;(3)愤怒组的学习判断准确性显著低于恐惧组。从而证明了情绪的确定性维度与学习判断之间的因果关系。     

Young Children's Reports of When Events Occurred: Do Event Type and Assessment Method Matter?

Studying young children's reporting about when various events occurred informs about the development of episodic memory and metacognition. In two experiments, 55 3‐ to 5‐year‐old children participated in two activity sessions, a week apart. During the activity sessions, they learned novel animal facts and body movements, and they coloured animal pictures and posed for body movement photos. Immediately after the second activity session, children were interviewed about when they experienced the various events. Overall, children were as accurate about learning events as physical events, but they were more accurate when asked temporal distance (e.g. ‘Which did you learn a longer time ago, “X” or “Y”?’) than temporal location questions (e.g. ‘Which did you learn before today, “X” or “Y”?’). The results suggest that young children's apparent difficulty recognizing new learning is not due to a rapid ‘remember‐to‐know shift’. Rather, the way we ask young children about when they experienced various events determines their accuracy. Copyright © 2016 John Wiley & Sons, Ltd.     

I Remember When You Taught Me That! Preschool Children's Memories of Realistic Learning Episodes

This study examined whether preschool children are able to identify the source of new knowledge that they acquired in a stimulating, interactive learning context. Sixty 4‐ to 5‐year‐old children participated in two staged learning events. Several days later, children were asked questions that assessed their knowledge of factual information presented during the events. Children indicated whether they knew the answer to each question and whether they remembered the moment they learned it (i.e. had an episodic memory of the learning event), and then recalled event details. A majority of preschoolers were able to accurately identify how they had learned at least some factual information, but this ability was not consistent across children and test items. Recall of event‐specific details was positively correlated with correct answers to factual questions. The results indicate that when preschool children are asked to reflect on past learning experiences that occurred in complex and realistic contexts, their source monitoring abilities are evident but not yet fully developed.

Being perceived as a knowledge sender or knowledge receiver: A multistudy investigation of the effect of age on knowledge transfer

As a result of demographic changes, workforces are becoming older and more age diverse. While interactions between workers from different age groups can provide opportunities for mutual learning through bidirectional knowledge transfer, research has yet to investigate how age influences knowledge transfer between age‐diverse colleagues. Building on the organizational theory of age effects, we conducted two studies to examine how age influenced the roles assigned to individuals in knowledge transfer processes, that is, whether they were perceived as knowledge senders or knowledge recipients. In Study 1, we used an experimental vignette design with 450 employees to assess how age affected perceived ability and motivation to share and receive knowledge. Further, we tested the extent to which trustworthiness moderated these relationships. In Study 2, we extended these findings using a dyadic research design with data from 53 age‐diverse knowledge transfer dyads. We examined through which mechanisms the age of one's colleague affected one's knowledge transfer behaviour. We found that the age of one's colleague had a positive effect on one's knowledge receiving behaviour and a negative effect on one's knowledge sharing behaviour. Further, perceived ability to receive knowledge and perceived motivation to share knowledge mediated these effects.     

The time course of location-avoidance learning in fear of spiders

Two experiments were designed to study the time course of avoidance learning in spider fearfuls (SFs) under controlled experimental conditions. To achieve this, we employed an immersive virtual environment (IVE): While walking freely through a virtual art museum to search for specific paintings, the participants were exposed to virtual spiders. Unbeknown to the participants, only two of four museum rooms contained spiders, allowing for avoidance learning. Indeed, the more SF the participants were, the faster they learned to avoid the rooms that contained spiders (Experiment. 1), and within the first six trials, high fearfuls already developed a preference for starting their search task in rooms without spiders (Experiment 2). These results illustrate the time course of avoidance learning in SFs, and they speak to the usefulness of IVEs in fundamental anxiety research.     

How students’ achievement goals shape their beliefs about effective teaching: A ‘build‐a‐professor’ study

Background. Which instructor qualities do students consider most important? The answer likely depends on the student. This study attempted to trace beliefs about the most essential instructor qualities to students’ academic achievement goals. Aims. The present study tested the hypothesis that students pursuing mastery goals favour instructors who stimulate and challenge them intellectually, whereas those pursuing performance goals favour instructors who present material clearly and provide clear cues about how to succeed. Sample. Participants were 157 students at a 4‐year public university. Method. Participants designed the ideal professor through a hypothetical combination of nine widely valued instructor qualities, such as enthusiasm, presentation clarity, and an interactive teaching style. The more they acquired of any one instructor quality, the less they could acquire of the others, thus compelling students to distinguish necessary qualities from desirable luxury qualities. Results. Students’ achievement goals corresponded to their views about the most essential instructor qualities. Mastery goals predicted greater demand for professors who intellectually challenge students and possess topic expertise, whereas performance goals predicted high demand for professors who present material clearly and provide cues about how to succeed in the course. Conclusions. The findings support emerging theorizing about how mastery and performance goals nudge students to pursue different learning agendas, with distinct consequences to their learning experience.     

儿童在因果知识领域内的选择性学习

儿童的选择性学习是目前认知发展领域的热点问题。儿童在因果知识领域内的选择性学习(即选择性因果学习)对于回答儿童如何获取知识这个经典问题具有重要意义。儿童的选择性因果学习表现在对他人解释的辨别、评估与采纳上。他们会主动向可靠的信息提供者寻求解释, 并在接收回答后表现出选择性跟进反应。对于他人的回答, 年幼儿童不仅能根据言语线索辨别出解释性陈述, 还能依据解释的结构特征选择更好的陈述加以采纳, 年长儿童甚至可以从不同模式的解释中灵活地学习更适宜的因果知识。未来研究应深入关注解释的其它特征在儿童选择性因果学习中的作用, 进一步探讨选择性因果学习的认知机制。     

The introductory class in higher education: Some old problems and new considerations

The traditional text and lecture format has remained the norm in introductory college courses despite evidence, such as the personalized system of instruction, that other practices could improve what is learned and retained. The growth of distance learning provides new opportunities to implement effective teaching practices. Unfortunately, an adequate comparison of various teaching practices is not possible (even with regard to the teaching of behavior analysis). Few practices have been assessed with respect to course-end effects (final exam performance), and longer term effects remain almost wholly unexplored. Studies of the retention of academic materials, the practice required for mastery or fluency, and the relation between verbal repertoires and correspondent everyday behaviors suggest course outcomes more modest than those hoped for earlier. Suggestions for changing current practices have little credibility until the size of the gap between present and possible learning outcomes is much better known, and the personal, social, and economic consequences of bridging that gap (or not) are assessed.     

A META‐ANALYTIC EXAMINATION OF THE INSTRUCTIONAL EFFECTIVENESS OF COMPUTER‐BASED SIMULATION GAMES

Interactive cognitive complexity theory suggests that simulation games are more effective than other instructional methods because they simultaneously engage trainees’ affective and cognitive processes ( Tennyson & Jorczak, 2008 ). Meta‐analytic techniques were used to examine the instructional effectiveness of computer‐based simulation games relative to a comparison group (k= 65, N= 6,476). Consistent with theory, posttraining self‐efficacy was 20% higher, declarative knowledge was 11% higher, procedural knowledge was 14% higher, and retention was 9% higher for trainees taught with simulation games, relative to a comparison group. However, the results provide strong evidence of publication bias in simulation games research. Characteristics of simulation games and the instructional context also moderated the effectiveness of simulation games. Trainees learned more, relative to a comparison group, when simulation games conveyed course material actively rather than passively, trainees could access the simulation game as many times as desired, and the simulation game was a supplement to other instructional methods rather than stand‐alone instruction. However, trainees learned less from simulation games than comparison instructional methods when the instruction the comparison group received as a substitute for the simulation game actively engaged them in the learning experience.     

Judging Knowledge in the Digital Age: The Role of External‐Memory Organization

Two studies examined relations between features of external‐memory repositories (personal computers) and confidence in knowing. Participants judged their confidence in knowledge related to their work or studies and then answered questions about the way they store and use information. Participants who maintained more organized repositories were more confident in their knowledge. Furthermore, moderation analyses showed that the participants who navigated through their files by manually clicking through folders to find documents, but not those who use an automated search feature, felt more knowledge confident if they maintained a well‐organized electronic repository. These results provide evidence for relation between assessments of internally ‘stored’ knowledge and the degree of organization of their externally stored ‘knowledge.’ Copyright © 2016 John Wiley & Sons, Ltd.     

Theory of mind selectively predicts preschoolers’ knowledge‐based selective word learning

Children can selectively attend to various attributes of a model, such as past accuracy or physical strength, to guide their social learning. There is a debate regarding whether a relation exists between theory‐of‐mind skills and selective learning. We hypothesized that high performance on theory‐of‐mind tasks would predict preference for learning new words from accurate informants (an epistemic attribute), but not from physically strong informants (a non‐epistemic attribute). Three‐ and 4‐year‐olds (N = 65) completed two selective learning tasks, and their theory‐of‐mind abilities were assessed. As expected, performance on a theory‐of‐mind battery predicted children's preference to learn from more accurate informants but not from physically stronger informants. Results thus suggest that preschoolers with more advanced theory of mind have a better understanding of knowledge and apply that understanding to guide their selection of informants. This work has important implications for research on children's developing social cognition and early learning.     

Hand Gesture and Mathematics Learning: Lessons From an Avatar

A beneficial effect of gesture on learning has been demonstrated in multiple domains, including mathematics, science, and foreign language vocabulary. However, because gesture is known to co‐vary with other non‐verbal behaviors, including eye gaze and prosody along with face, lip, and body movements, it is possible the beneficial effect of gesture is instead attributable to these other behaviors. We used a computer‐generated animated pedagogical agent to control both verbal and non‐verbal behavior. Children viewed lessons on mathematical equivalence in which an avatar either gestured or did not gesture, while eye gaze, head position, and lip movements remained identical across gesture conditions. Children who observed the gesturing avatar learned more, and they solved problems more quickly. Moreover, those children who learned were more likely to transfer and generalize their knowledge. These findings provide converging evidence that gesture facilitates math learning, and they reveal the potential for using technology to study non‐verbal behavior in controlled experiments.     

Incidental Learning of Melodic Structure of North Indian Music

Musical knowledge is largely implicit. It is acquired without awareness of its complex rules, through interaction with a large number of samples during musical enculturation. Whereas several studies explored implicit learning of mostly abstract and less ecologically valid features of Western music, very little work has been done with respect to ecologically valid stimuli as well as non‐Western music. The present study investigated implicit learning of modal melodic features in North Indian classical music in a realistic and ecologically valid way. It employed a cross‐grammar design, using melodic materials from two modes (rāgas) that use the same scale. Findings indicated that Western participants unfamiliar with Indian music incidentally learned to identify distinctive features of each mode. Confidence ratings suggest that participants' performance was consistently correlated with confidence, indicating that they became aware of whether they were right in their responses; that is, they possessed explicit judgment knowledge. Altogether our findings show incidental learning in a realistic ecologically valid context during only a very short exposure, they provide evidence that incidental learning constitutes a powerful mechanism that plays a fundamental role in musical acquisition.
