Metamemory judgments for familiar and unfamiliar tunes

Metamemory is an important skill that allows humans to monitor their own memory abilities; however, little research has concerned what perceptual information influences metamemory judgments. A series of experiments assessed the accuracy of metamemory judgments for music as well as determined if metamemory judgments are affected by ease of processing of musical features. A recognition memory task inconjunction with metamemory judgments (Judgments of Learning, or JOLs) were used to determine actual and predicted memory performance. We found that changing the ease of processing of the volume and timbre of unfamiliar tunes affected metamemory judgments, but not memory performance, for unfamiliar tunes. Manipulating the ease ofprocessing of the timbre and tempo of familiar tunes did not affect metamemory judgments or memory performance although metamemory accuracy on an item-by-item basis was better for familiar tunes as compared to unfamiliar tunes. Thus, metamemory judgments for unfamiliar tunes are more sensitive to ease of processing changes ascompared to familiar tunes, suggesting that different types of information are processed in different ways.

A Test of Absolute Numerousness Judgments in Lion-Tailed Macaques (Macaca Silenus)

Numerous studies have shown that animals have a sense of quantity and can distinguish between relative amounts. The concepts of relative numerousness, estimation, and subitizing are well established in species as diverse as chimpanzees and salamanders. Mobile animals have practical use for an understanding of number in common situations such as predation, mating, and competition. However, the ability to identify discrete quantities has only been firmly established in humans. The purpose of this study was to test for such “absolute numerousness” judgments in three lion-tailed macaques (Macaca silenus), a non-human primate. The three macaques tested had previously been trained on a computerized matchto- sample (MTS) task using geometric shapes. In this study, they were introduced to a MTS task containing a numerical cue, which required the monkeys to match stimuli containing either one or two items for rewards. If monkeys were successful at the initial matching task, they were tested with stimuli in which the position of the items and then the surface area of the items was controlled. If the monkeys could match successfully without using these non-numerical cues, they would demonstrate the capability to make absolute numerousness judgments. None of the monkeys matched successfully using the numerical cue, so no evidence of absolute numerosity was found. Each macaque progressed through the experiment in an individualized manner, attempting a variety of strategies to obtain rewards. These included side preferences and an alternating-side strategy that were unrelated to the numerical cues in the stimuli. When it became clear that the monkeys were not matching based on a stimulus-based cue, they were tested again on matching geometric shapes. All three macaques stopped using their alternate strategies and were able to match shapes successfully, demonstrating that they were still capable of completing the matching task. The data suggest that the monkeys could not transfer this ability to the numerical stimuli. This indicates that the macaques lack a sense of exact quantity, or that they could not recognize the numerical cues in the stimuli as being relevant to the task.

Diverse Readings of the Court of Justice Judgments on Copyright Work

EU law’s impact on the meaning of the copyright work for a long time seemed limited to software and databases. But recent judgments of the CJEU (Infopaq, BSA, FootballAssociation [Murphy], Painer) suggest we have entered an era of harmonization of copyright subject-matter, after decades of focus on the scope of exclusive rights and their duration. Unlike before however, it is the Court and not the legislator that takes centre stage in shaping pivotal concepts. This article reviews the different readings and criticisms the recent case law on copyright works evokes in legal doctrine across the EU. It puts them in the wider perspective of the on-goingdevelopment towards uniform law and the role of the preliminary reference procedure in that process.

Polarity correspondence in comparative number magnitude judgments

When asked which of two digits is greater, participants respond more quickly if physical size corresponds to number magnitude, such as in 3 7, than when the two attributes contradict each other, such as in 3 7. This size congruence effect in comparative number judgments is a well-documented phenomenon. We extended existing findings by showing that this effect does not depend on physical size of the number alone but can be observed with number symmetry. In addition, we observed that symmetric numbers are judged as being smaller than asymmetric numbers, which renders an interpretation of the number symmetry congruence effect in terms of physical size implausible. We refer to the polarity correspondence principle (Proctor & Cho, 2006) to explain the present findings.
