Overcoming Collaborative Inhibition through Error Correction: A Classroom Experiment

Research in classrooms has shown mixed evidence for benefits of collaborative learning compared with learning individually. Moreover, laboratory research has shown that individuals working in dyads or groups often perform worse than individuals working alone — a robust finding called the collaborative inhibition effect. Despite these findings, we hypothesize that some classroom activities may afford benefits for collaborative learning over individual learning. We created a classroom writing activity that incorporated features such as shared prior knowledge and error‐correction processes, which have been hypothesized to eliminate collaborative inhibition and to support constructive collaboration. Students participated in this activity either individually or in dyads. Results showed that the individuals who worked collaboratively performed equally well as those who worked individually and also showed better learning as measured by performance on a future writing assignment.

Collaboration facilitates abstract category learning

We examined the effects of collaboration (dyads vs. individuals) and category structure (coherent vs. incoherent) on learning and transfer. Working in dyads or individually, participants classified examples from either an abstract coherent category, the features of which are not fixed but relate in a meaningful way, or an incoherent category, the features of which do not relate meaningfully. All participants were then tested individually. We hypothesized that dyads would benefit more from classifying the coherent category structure because past work has shown that collaboration is more beneficial for tasks that build on shared prior knowledge and provide opportunities for explanation and abstraction. Results showed that dyads improved more than individuals during the classification task regardless of category coherence, but learning in a dyad improved inference-test performance only for participants who learned coherent categories. Although participants in the coherent categories performed better on a transfer test, there was no effect of collaboration.     

The effect of peer collaboration on children's problem‐solving ability

Background. A Vygotskian framework links cognitive change to collaborative interaction with a more competent partner whereas a Piagetian perspective supports the view that cognitive conflict arising from peer interaction leads to cognitive change. Aims. The study investigated the effect of collaborative learning on children's problem‐solving ability and whether differences in knowledge status or the use of explanatory language were contributing factors. Sample. Participants were 100 Year 2 children (aged between 6 and 7 years), from schools in high socio‐economic areas, who individually completed a pre‐ and post‐test comprising a block sorting task. Method. During the experimental phase, children completed a card sorting activity, either individually or in same‐gender dyads. The dyads consisted of same or different ability children who operated under either a ‘talk’ or ‘no‐talk’ condition. Results. It was found that children who collaborated collectively obtained a significantly higher number of correct sorts than children who worked individually. However, post‐testing indicated that only those children of lower sorting ability who collaborated with higher sorting ability peers showed a significant improvement in sorting ability from pre‐test scores. In addition, it was found that when analysis was limited to this particular group, only those children who were required to explain the sort for their partner to carry out improved significantly from pre‐ to post‐test. Conclusion. It is suggested that perhaps the two theoretical positions are not as mutually exclusive as they are often portrayed. Implications of these findings for teachers and children's learning are also discussed.     

Recognition and recall performance both benefit from the production effect with content-specific information

Two experiments assessed how reading aloud versus reading silently would benefit recognition and recall performance of content-specific vocabulary (i.e., the production effect). Participants studied 30 terms from an American history curriculum by reading half of the vocabulary aloud, while the remaining words were read silently. After a brief distractor task, they completed a recognition memory test (Experiment 1) or a recall memory test (Experiment 2). Both experiments revealed a benefit for reading aloud. Recognition performance showed a 22% performance advantage, while recall performance showed a smaller advantage for the words read aloud (8% benefit). The vast majority of participants in both experiments showed a memory advantage for those words that were studied aloud versus those read silently (88% of participants in Experiment 1 and 67% of individuals in Experiment 2). Implications for educational settings are considered.

Attempts to improve student performance have been manifested in various forms; however, recent developments in cognitive psychology have a great deal to offer educators and students regarding instruction and learning. Studies suggest that educators and cognitive psychologists ought to approach educational research as an interdisciplinary endeavor. Through this collaborative relationship, those who teach could improve their understanding of the science of learning, while researchers extend theoretical research to practical, classroom applications for the benefit of students and teachers.     

When training with a partner is inferior to training alone: the importance of dyad type and interaction quality

Dyad training, where trainees learn in pairs but ultimately perform individually, has been shown to be an effective method for training some skills. The effectiveness of this approach, however, may be tied to the type of task to be trained and the quality of the interaction in the dyad. We report two studies on the effectiveness of dyad training and the role of metacognitive activity for learning a software program. In Study 1, participants completed training alone or with a partner. Performance was assessed individually immediately after training and again after a 1-week nonuse interval. Results of Study 1 suggested that learning retention is superior when people are trained individually. Study 2 examined performance for individuals, task-switching dyads, and interdependent dyads. Results also showed that performance for individuals was superior to dyads and that the type of dyad collaboration did not affect performance. However, partner-prompted metacognitive activity was helpful for interdependent dyads and harmful for task-switching dyads, suggesting that the quality of collaboration varies by dyad type. Our findings suggest that dyad training may not be effective for all types of tasks. Possible boundary conditions for effective dyad training are discussed.     

Observing tutorial dialogues collaboratively: insights about human tutoring effectiveness from vicarious learning

The goals of this study are to evaluate a relatively novel learning environment, as well as to seek greater understanding of why human tutoring is so effective. This alternative learning environment consists of pairs of students collaboratively observing a videotape of another student being tutored. Comparing this collaboratively observing environment to four other instructional methods—one-on-one human tutoring, observing tutoring individually, collaborating without observing, and studying alone—the results showed that students learned to solve physics problems just as effectively from observing tutoring collaboratively as the tutees who were being tutored individually. We explain the effectiveness of this learning environment by postulating that such a situation encourages learners to become active and constructive observers through interactions with a peer. In essence, collaboratively observing combines the benefit of tutoring with the benefit of collaborating. The learning outcomes of the tutees and the collaborative observers, along with the tutoring dialogues, were used to further evaluate three hypotheses explaining why human tutoring is an effective learning method. Detailed analyses of the protocols at several grain sizes suggest that tutoring is effective when tutees are independently or jointly constructing knowledge: with the tutor, but not when the tutor independently conveys knowledge.     

Test expectancy affects metacomprehension accuracy

Background. Theory suggests that the accuracy of metacognitive monitoring is affected by the cues used to judge learning. Researchers have improved monitoring accuracy by directing attention to more appropriate cues; however, this is the first study to more directly point students to more appropriate cues using instructions regarding tests and practice tests. Aims. The purpose of the present study was to examine whether the accuracy metacognitive monitoring was affected by the nature of the test expected. Sample and method. Students (N= 59) were randomly assigned to one of two test expectancy groups (memory vs. inference). Then after reading texts, judging learning, completed both memory and inference tests. Results. Test performance and monitoring accuracy were superior when students received the kind of test they had been led to expect rather than the unexpected test. Conclusion. Tests influence students' perceptions of what constitutes learning. Our findings suggest that this could affect how students prepare for tests and how they monitoring their own learning.     

The collaborative encoding deficit is attenuated with specific warnings

Individuals learning together do so less effectively than individuals learning alone, an effect known as the collaborative encoding deficit. In the present studies we examined whether providing participants with a warning about the collaborative encoding deficit would increase their encoding task performance, and reduce subsequent memory deficits. Across two experiments, specific warnings were beneficial for memory. Collaborating participants who were told about the collaborative encoding deficit, and who received suggestions for how to complete the encoding task, had superior memory than participants who received no warning. This benefit was not due to qualitative changes in encoding task performance, was unrelated to the type of collaboration utilised, was absent when a more general warning was utilised, and was unrelated to self-reported task motivation. Rather, specific warnings appear to protect against the collaborative encoding deficit by increasing time spent on, and attention directed to, the encoding task.     

What’s good for me depends on what I see in you: Intimacy avoidance and resources derived from close others

Past research has demonstrated that comfort with intimacy differentially affects the extent to which a person assimilates/contrasts to a close other. Specifically, individuals comfortable with intimacy benefit most from assimilating to those who embody positive aspects, whereas individuals uncomfortable with intimacy benefit most from contrasting to those who embody a mix of positive and negative aspects. Using a multi-method approach, the current research provides evidence suggesting that both those who are positively regarded and those who engender mixed feelings have the potential to benefit the perceiver differentially as a function of the types of traits that are most salient at the time. In Study 1, consistent with predictions, high-avoidant individuals contrasted to the salient traits of a romantic partner and performed better on an intelligence test after thinking about their partner’s unintelligent compared to intelligent traits, whereas low-avoidant individuals assimilated. In Study 2, high-avoidant individuals contrasted to friends’ traits and exhibited more positive cardiovascular responses (i.e., greater challenge) while talking about friends’ negative traits and more negative responses (i.e., greater threat) while talking about friends’ positive traits. Together, these findings suggest that there are situations during which low- and high-avoidant individuals differentially benefit from highly regarded close others.     

Collaborative testing for key-term definitions under representative conditions: Efficiency costs and no learning benefits

Students are expected to learn key-term definitions across many different grade levels and academic disciplines. Thus, investigating ways to promote understanding of key-term definitions is of critical importance for applied purposes. A recent survey showed that learners report engaging in collaborative practice testing when learning key-term definitions, with outcomes also shedding light on the way in which learners report engaging in collaborative testing in real-world contexts (Wissman & Rawson, 2016, Memory, 24, 223–239). However, no research has directly explored the effectiveness of engaging in collaborative testing under representative conditions. Accordingly, the current research evaluates the costs (with respect to efficiency) and the benefits (with respect to learning) of collaborative testing for key-term definitions under representative conditions. In three experiments (ns = 94, 74, 95), learners individually studied key-term definitions and then completed retrieval practice, which occurred either individually or collaboratively (in dyads). Two days later, all learners completed a final individual test. Results from Experiments 1–2 showed a cost (with respect to efficiency) and no benefit (with respect to learning) of engaging in collaborative testing for key-term definitions. Experiment 3 evaluated a theoretical explanation for why collaborative benefits do not emerge under representative conditions. Collectively, outcomes indicate that collaborative testing versus individual testing is less effective and less efficient when learning key-term definitions under representative conditions.     

Rethinking Collaborative Learning Through Participation in an Interdisciplinary Research Project: Tensions and Negotiations as Key Points in Knowledge Production

As social and cultural psychologists of learning, we are persuaded of the crucial role of interaction in development and learning. But how do we experience this assumption in our own research practices and in our collaboration with colleagues? Taking as our object of study our own participation in a European Research and Development project that aimed to enhance interactive and argumentative skills in learning settings, this study shows how collaboration among project partners is not something that is to be taken for granted, but something that is elaborated and evolves in time, takes diverse forms, and is mediated by multiple tools. The psychological processes—more particularly tensions and negotiation—involved in collaboration are developed and discussed. The study explores the processes of establishing collaboration and, through the analysis of specific zones of tensions, sheds light on the way new knowledge (on how to do research, how to communicate, how to work together) is constructed. It contributes to the understanding of the issues and conditions for the development of a community of practice.     

Conscious and unconscious forms of memory in different implicit tests

This study investigated how shallow processing (complexity rating), deep processing (pleasantness rating), and semantic generation (translating from English) of Chinese words affects conscious memory (CM) and unconscious memory (UM) of the words with three implicit tests: word association, word identification, and word-stem completion. A metacognition-based dissociation procedure was used to estimate the two forms of memory for each test. Except for the shallow condition preceding the word-association test, all three study conditions produced a positive effect on the estimate of CM. The estimate of UM did not benefit from any of the study conditions in the word-association test, it benefited from the shallow and deep conditions but did not benefit from the generation condition in the stem-completion test, and it benefited from the shallow condition but did not benefit from the deep and generation conditions in the word-identification test. Implications of these results for CM and UM operations are discussed.     

Does limiting pre-movement time during practice eliminate the benefit of practicing while expecting to teach?

Past research has revealed practicing and studying a motor skill with the expectation of teaching it to another person increases the amount of time participants spend preparing for movement during practice trials of the skill. However, it is unknown whether the increased motor preparation time explains the benefit of expecting to teach on motor learning. To address this question, we had participants practice golf putting with the expectation of teaching the skill to another participant the following day or the expectation of being tested on the skill the following day. We limited the motor preparation time for half of the participants who expected to teach and half of the participants who expected to test, and allowed the remaining participants to take as much motor preparation time as they liked. All participants were tested on their putting the next day. We predicted that participants who expected to teach would exhibit superior posttest performance, but this benefit would be exclusive to those participants who also practiced with unlimited motor preparation. Although the current data did not support this hypothesis, we also conducted an exploratory analysis in which we aggregated data from two prior experiments. This cumulative analysis suggested that expecting to teach does indeed enhance motor learning, but not through motor preparation during practice.     

Influencing organizational commitment through office redesign

Prior research on the effects of office redesign on work-related outcomes has been largely atheoretical and yielded mixed and conflicting findings. Expanding on individual reactions to office design changes as specified by social interference theory, we propose that office redesign affects organizational commitment and this relationship is mediated by employee perceptions of the broader work environment. This conceptual model is tested using 121 financial services employees who experience office redesign and 136 who do not. Results indicate that perceptions of innovation and collaboration mediate the effects of office redesign over and above negative personal reactions such that affective organizational commitment is enhanced among those experiencing reconfigured offices. Findings provide support for an expanded rendition of social interference theory that provides for favorable (as well as unfavorable) employee reactions to office redesign. Such a theoretical explanation is asserted to increase understanding of how the physical environment influences employee attitudes.     

Partial reinforcement and breadth of learning

Two experiments on partial reinforcement were undertaken to test predictions made by a two process model of discrimination learning. In the first experiment rats were trained on a discrimination involving two relevant cues: one group (C) was trained on a 100: o schedule, the other (P) on a 50:0 schedule. Both groups were then given transfer tests with the two cues presented individually; finally all animals were extinguished on the original training stimuli and on the single cue stimuli. During extinction there was a negative correlation between the number of correct responses made by individual subjects of Group C to each single cue; whereas the correlation was positive for subjects of Group P. The second experiment employed basically the same design, but subjects were trained with seven relevant cues. The results of transfer tests showed that subjects of Group P learned to attach the correct response to many more cues than subjects of Group C. This suggests that the breadth of learning is greater under partial than under consistent reinforcement. The results were predicted by the model of discrimination learning under test.     

Social anxiety in stuttering: measuring negative social expectancies

Much research has suggested that those who stutter are likely to be anxious. However, to date, little research on this topic has addressed the role of expectancies of harm in anxiety, which is a central construct of anxiety in modern clinical psychology. There are good reasons to believe that the anxiety of those who stutter is related to expectancies of social harm. Therefore, in the present study, 34 stuttering and 34 control participants completed the Fear of Negative Evaluation (FNE) Scale and the Endler Multidimensional Anxiety Scales-Trait (EMAS-T). The FNE data showed a significant difference between the stuttering and control participants, with a large effect size. Results suggested that, as a group, a clinical population of people who stutter has anxiety that is restricted to the social domain. For the EMAS-T, significant differences between groups were obtained for the two subtests that refer specifically to people and social interactions in which social evaluation might occur (Social Evaluation and New/Strange Situations) but not for the subtests that contained no specific reference to people and social interactions (Physical Danger and Daily Routines). These results were taken to suggest that those who stutter differ from control subjects in their expectation of negative social evaluation, and that the effect sizes are clinically significant. The findings also suggest that the FNE and the EMAS-T are appropriate psychological tests of anxiety to use with stuttering clients in clinical settings. The clinical and research implications of these findings are discussed, in terms of whether social anxiety mediates stuttering or is a simple by-product of stuttering. Possible laboratory explorations of this issue are suggested, and potential Cognitive Behavior Therapy packages for stuttering clients who might need them are discussed. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) explain why expectancy of social threat or harm may be associated with stuttering; (2) name and describe two psychological tests that are suitable for assessment of the social threat or harm that may be associated with stuttering; and (3) explain how findings for the EMAS-T test in the present results suggest that expectancy of social threat or harm, but not other kinds of negative expectancy, are associated with stuttering.

学习和测验经验对学习判断中UWP效应的影响

针对重复学习判断中出现的练习伴随低估效应（UWP效应）,目前存在多种理论解释。本研究基于过去测验记忆假说,在学习阶段和测验阶段引入两种判断：学习判断准确性的判断和回溯性信心判断,通过两个实验考察学习经验和测验经验对UWP效应的影响。结果发现：在学习判断中学习判断准确性的判断和回溯性信心判断均消除了UWP效应,间接证明了学习和测验经验均影响到UWP效应的出现。
