Existing research suggests that adults and older children experience a tradeoff where instruction and feedback help them solve a problem efficiently, but lead them to ignore currently irrelevant information that might be useful in the future. It is unclear whether young children experience the same tradeoff. Eighty-seven children (ages five- to eight-years) and 42 adults participated in supervised feature prediction tasks either with or without an instructional hint. Follow-up tasks assessed learning of feature correlations and feature frequencies. Younger children tended to learn frequencies of both relevant and irrelevant features without instruction, but not the diagnostic feature correlation needed for the prediction task. With instruction, younger children did learn the diagnostic feature correlation, but then failed to learn the frequencies of irrelevant features. Instruction helped older children learn the correlation without limiting attention to frequencies. Adults learned the diagnostic correlation even without instruction, but with instruction no longer learned about irrelevant frequencies. These results indicate that young children do show some costs of learning with instruction characteristic of older children and adults. However, they also receive some of the benefits. The current study illustrates just what those tradeoffs might be, and how they might change over development.

The debate regarding the best way to test and measure eyewitness memory has dominated the eyewitness literature for more than thirty years. We argue that to resolve this debate requires the development and application of appropriate measurement models. In this study we develop models of simultaneous and sequential lineup presentations and use these to compare the procedures in terms of discriminability and response bias. We tested a key prediction of the diagnostic feature detection hypothesis that discriminability should be greater for simultaneous than sequential lineups. We fit the models to the corpus of studies originally described by Palmer and Brewer (2012, Law and Human Behavior, 36(3), 247-255) and to data from a new experiment. The results of both investigations showed that discriminability did not differ between the two procedures, while responses were more conservative for sequential presentation compared to simultaneous presentation. We conclude that the two procedures do not differ in the efficiency with which they allow eyewitness memory to be expressed. We discuss the implications of this for the diagnostic feature detection hypothesis and other sequential lineup procedures used in current jurisdictions.

AbstractHuman tool behavior is species-specific. It remains a diagnostic feature of humans, even when comparisons are made with closely related non-human primates. The archaeological record demonstrates both the deep antiquity of human tool behavior and its fundamental role in distinguishing human behavior from that of non-human primates.

Abstract This article provides an overview of the pathology of alveolar soft part sarcoma, focused on its morphology, special stains useful in diagnosis, and the clinical and radiographic features of the disease. Alveolar soft part sarcoma is a rare neoplasm of unknown histogenesis with poor prognosis. Although there are several immunohistochemical stains available to help reach the diagnosis, the morphology of the tumor should be considered the main diagnostic feature. The periodic acid–Schiff stain is the best single stain that supports the diagnosis.

A study of morphological characteristics in cross sections of Dirofilaria subdermata adults from the subcutaneous tissues of the Canadian porcupine (Erethizon dorsatum) is reported. A useful diagnostic feature which differentiates D. subdermata from a closely related filarid, D. ursi, occurring in bears, was found to be the number of longitudinal ridges. The relevance of these findings are discussed in relation to the human subcutaneous infections found in the United States and Canadian border states and provinces with D. ursi.

Within the Romanesque abbey church at St Albans (Hertfordshire), the vestiges of an earlier structure have been identified for the first time. A hitherto unrecorded feature in the transept, noted by the author in 2017, indicates that, at some stage, the nave lacked its existing arcade piers and instead had solid walls. The implications of this are considerable, calling for a thorough reassessment of the building’s history. For now, it is important to record the primary evidence, so as to make it available for further research. This article aims to provide a concise account of the evidence and a summary of what it might mean. According to the thirteenth-century chronicler, Matthew Paris, the existing church was begun in 1077 and completed in 1088. New evidence indicates, however, that the Romanesque building, with its aisled nave and presbytery, was preceded by a cruciform structure without aisles. The inference is that the existing building contains the fabric of this unaisled predecessor. The obvious conclusion – that it therefore represents the lost Anglo-Saxon abbey church – does not follow without question; as yet, excavation has yielded no conclusive evidence of an earlier church on the site. The critical diagnostic feature presented here for the first time adds substance to the view that the remodelling of unaisled buildings was not uncommon in the post-Conquest period, including large as well as minor churches, as identified long ago at York Minster and, more recently, at Worksop Priory.
