The Effect of Retrieval Practice in Primary School Vocabulary Learning

The testing effect refers to the finding that retrieval practice leads to better long‐term retention than additional study of course material. In the present study, we examined whether this finding generalizes to primary school vocabulary learning. We also manipulated the word learning context. Children were introduced to 20 words by listening to a story in which novel words were embedded (story condition) or by listening to isolated words (word pairs condition). The children practised the meaning of 10 words by retrieval practice and 10 words by restudy. After 1 week, they completed a cued recall test and a multiple choice test. Words learned by retrieval practice were recalled better than words learned by additional study, but there was no difference in recognition. Furthermore, the children in the word pairs condition outperformed the children in the story condition. These results show that retrieval practice may improve vocabulary learning in children.

Gestures in Instructional Animations: A Helping Hand to Understanding Non‐human Movements?

Recent research on dynamic visualizations suggests that these visualizations are effective for learning human movements such as knot tying or paper folding. Using embodied theories of cognition, this study investigated whether learning non‐human movements from a dynamic visualization can also be enhanced by grounding these movements in the learner's motor system. University students viewed an animation on lightning formation, and followed the animation's movements with gestures, saw an on‐screen human hand follow the movements or saw an arrow follow the movements. Results showed that observing an on‐screen human hand following the movements in the animation, but not actually performing these movements, enhanced retention and transfer performance compared with watching the animation without gestures. This suggests that observation of human hand movement in animation‐based instruction, which plays an important role in learning of procedural‐motor tasks, can also improve people's learning from other dynamic systems.

Effects of gain versus loss and certain versus probable outcomes on social value orientations

In an experiment, the effects of types of outcomes on social value orientations (individualism, competition, pro‐social orientation) were investigated. Ninety‐nine students made 28 choices which affected outcomes (points to be converted into money) for themselves and another (unknown) person. About half of them started out with nothing but they could allocate positive outcomes (gains) to themselves and/or the other. The other half were told that they themselves and another person would start out with some outcomes but they could lose outcomes depending on the choices. For about half the participants it was certain that their choices would result in outcomes while for the other half outcomes would be likely rather than certain. The expected utility of the outcomes was the same in the four conditions. In accordance with prospect theory, it was expected and found that participants would be more individualistic in the conditions with losses than in the conditions with gains. In accordance with social comparison theory, it was expected and found that participants would be more competitive in the conditions with probable outcomes than in the conditions with certain outcomes.

Explicating pluralism: Where the mind to molecule pathway gets off the track—Reply to Bickle

It is argued that John Bickle’s Ruthless Reductionism is flawed as an account of the practice of neuroscience. Examples from genetics and linguistics suggest, first, that not every mind-brain link or gene-phenotype link qualifies as a reduction or as a complete explanation, and, second, that the higher (psychological) level of analysis is not likely to disappear as neuroscience progresses. The most plausible picture of the evolving sciences of the mind-brain seems a patchwork of multiple connections and partial explanations, linking anatomy, mechanisms and functions across different domains, levels, and grain sizes. Bickle’s claim that only the molecular level provides genuine explanations, and higher level concepts are just heuristics that will soon be redundant, is thus rejected. In addition, it is argued that Bickle’s recasting of philosophy of science as metascience explicating empirical practices, ignores an essential role for philosophy in reflecting upon criteria for reduction and explanation. Many interesting and complex issues remain to be investigated for the philosophy of science, and in particular the nature of interlevel links found in empirical research requires sophisticated philosophical analysis.     

Learning to calibrate: Providing standards to improve calibration accuracy for different performance levels

This experimental study explores whether feedback in the form of standards helps students in giving more accurate performance estimates not only on current tasks but also on new, similar tasks and whether performance level influences the effect of standards. We provided 122 first‐year psychology students with seven texts that contained key terms. After reading each text, participants recalled the correct definitions of the key terms and estimated the quality of their recall. Half of the participants subsequently received standards and again estimated their own performance. Results showed that providing standards led to better calibration accuracy, both on current tasks and on new, similar tasks, when standards were not available yet. Furthermore, with or without standards, high performers calibrated better than low performers. However, results showed that especially low performers' calibration accuracy benefitted from receiving standards.
