Almost self-fulfilling, commonly held negative stereotypes about old age and memory can impair older adults’ episodic memory performance, due to age-based stereotype threat or self-stereotyping effects. Research studies demonstrating detrimental impacts of age stereotypes on memory performance are generally conducted in research laboratories or medical settings, which often underestimate memory abilities of older adults. To better understand the “real world” impact of negative age and memory stereotypes on episodic memory, the present research tested story recall performance of late middle-aged and (...) older adults following a naturalistic age stereotype manipulation, wherein every day, newspaper-style materials were either embedded with negative age and memory stereotype stimuli or neutral stimuli. Furthermore, all participants were tested in favorable, familiar environments. Potential moderators of the stereotype effects, e.g., metamemory beliefs, were assessed at baseline. Current memory evaluation and subjective age, as well as perceived stereotype threat and task-related anxiety, were assessed following the stereotype manipulation as potential mechanisms of the expected stereotype effects. Results suggested a contrast effect, as the stereotype group demonstrated superior story recall performance compared to the control group. Marginally significant moderation effects by age and perceived stereotype threat indicated that stereotype rejection was present for late middle-aged adults but not older adults, indicative of stereotype lift, and for individuals who reported low and average, but not high, levels of perceived stereotype threat. Additionally, a trend suggested more positive memory evaluation for those in the stereotype group who reported awareness of the stereotype stimuli than those who did not notice the stimuli. These results are consistent with other research demonstrating benefits to memory performance in adulthood based on motivational and contextual factors, such as using relevant memory materials and testing in favorable conditions. Moreover, the results of this study contribute to our understanding of individuals’ responses to different types of stereotype stimuli, and the differential impact of stereotype manipulations that are subtle versus blatant. Individuals were motivated to counteract negative stereotype effects when conditions were supportive, stereotype presentations were naturalistic, and personal beliefs were positive. (shrink)

Disagreement about the nature of ‘addiction’, such as whether it is a brain disease, arises in part because the label is applied to a wide range of phenomena. This creates conceptual and definitional confusions and misunderstandings, often leading to researchers talking past one another. Ontologies have been successfully implemented in other fields to help solve these problems by creating unifying frameworks that can accommodate divergence while clarifying the basis for it. We argue that ontologies can help transform the way we (...) think and communicate about addiction as well, providing a basis for a shared understanding of the domain and a shared means for communicating and achieving that understanding. -/- We introduce the use of ontologies in science and medicine and show how they can unify differing perspectives on addiction. We also show how ontologies provide a practical tool for organizing our collective knowledge in this field, even, and especially, when that knowledge is garnered through distinct disciplinary approaches adopting disparate methodologies or perspectives (e.g., neurobiological, psychological, sociological, etc.). In the end, we believe that ontologies can help to avoid letting questions like “Is addiction a brain disease?” divide the field, hamper communication, or otherwise disrupt the ability to make meaningful progress.

Oxford Scholarly Classics is a new series that makes available again great academic works from the archives of Oxford University Press. Reissued in uniform series design, the reissues will enable libraries, scholars, and students to gain fresh access to some of the finest scholarship of the last century.

We demonstrate that the key components of cognitive architectures (declarative and procedural memory) and their key capabilities (learning, memory retrieval, probability judgment, and utility estimation) can be implemented as algebraic operations on vectors and tensors in a high‐dimensional space using a distributional semantics model. High‐dimensional vector spaces underlie the success of modern machine learning techniques based on deep learning. However, while neural networks have an impressive ability to process data to find patterns, they do not typically model high‐level cognition, and (...) it is often unclear how they work. Symbolic cognitive architectures can capture the complexities of high‐level cognition and provide human‐readable, explainable models, but scale poorly to naturalistic, non‐symbolic, or big data. Vector‐symbolic architectures, where symbols are represented as vectors, bridge the gap between the two approaches. We posit that cognitive architectures, if implemented in a vector‐space model, represent a useful, explanatory model of the internal representations of otherwise opaque neural architectures. Our proposed model, Holographic Declarative Memory (HDM), is a vector‐space model based on distributional semantics. HDM accounts for primacy and recency effects in free recall, the fan effect in recognition, probability judgments, and human performance on an iterated decision task. HDM provides a flexible, scalable alternative to symbolic cognitive architectures at a level of description that bridges symbolic, quantum, and neural models of cognition. (shrink)

A Papyrus commentary on Alcman published in 19571 brings us news of a poem in which Alcman “physiologized”. The lemmata and commentary together witness to a semi-philosophical cosmogony unlike any other hitherto known from Greece. The evidence is meagre, but it seems worth while to see what can be made of it; for it is perhaps possible to go a little farther than has so far been done.

In the long section of anapaests with which they make their entry, the old men of Argos methodically deliver three essential messages to the audience: 40–71. It is the tenth year of the Trojan War. 72–82. We are men who were too old to go and fight in it. 83–103. Some new situation seems to be indicated by the fact that Clytemnestra is organizing sacrifices throughout the town.

It is generally accepted that the Homeric Hymn to Apollo was not conceived as a single poem but is a combination of two: a Delian hymn, D, performed at Delos and concerned with the god's birth there, and a Pythian hymn, P, concerned with his arrival and establishment at Delphi. What above all compels us to make a dichotomy is not the change of scene in itself, but the way D ends. The poet returns from the past to the present, (...) and takes leave of his audience; farewell, he says, and remember me ever after. He is quite clearly finishing. Whereupon there is an abrupt and unsatisfactory transition to P. (shrink)

Histories of literature tend to treat Stesichorus as just one of the lyric poets, like Alcman or Anacreon. But the vast scale of his compositions puts him in a category of his own. It has always been known that his Oresteia was divided into more than one book; P. Oxy, 2360 gave us fragments of a narrative about Telemachus of a nearly Homeric amplitude; and from P. Oxy. 2617 it was learned that the Geryoneis contained at least 1,300 verses, the (...) total being perhaps closer to two thousand. Even allowing for the shorter lines, this was as long as many an epic poem. Indeed, these were epic poems, in subject and style as well as in length: epics to be sung instead of recited. What was behind them ? Who was this Stesichorus, and how did he come to be, in Quintilian's phrase, ‘sustaining on the lyre the weight of epic song’ ? The biographical problem must be tackled first. The question of Stesichorus’ historical setting and date is confused by legendary elements as well as by contradiction in the sources. On the whole scholars remain spellbound by the specious precision of the Suda's dates , although it has long been realized that they are founded on nothing but the assumption that Stesichorus was younger than Alcman and older than Simonides. There have been excellent discussions by Wilamowitz and Maas, but they seem to have had little influence. (shrink)

The work of many scholars in the last hundred years has helped us to understand the nature and origins of the treatise which we know for short as the Contest of Homer and Hesiod. The present state of knowledge may be summed up as follows. The work in its extant form dates from the Antonine period, but much of it was taken over bodily from an earlier source, thought to be the Movaelov of Alcidamas. Some of the verses exchanged in (...) the contest were current even earlier, and some scholars have supposed that the story of a contest went back to the fifth, sixth, or even eighth century; but this is now much doubted.

The grammarian Marius Plotius Sacerdos, whose work is to be found in Keil's Grammatici Latini, vi. 427–546, quotes a number of Greek verses, whose authors he does not specify, to illustrate various metres. He derives them from some earlier Greek metrician, whose practice, like Hephaestion's, was to take his examples from the beginnings of poems. In most cases they have been corrupted by copyists who knew no Greek, sometimes so badly that where the verse is not known from another source (...) it can no longer be restored. But unlike corruptions in Greek traditions, they are almost purely visual in nature. (shrink)

It is universally recognized that the Hymn to Ares stands apart from all the other poems in the Homeric collection, and that it was composed centuries later than any of those that can be assigned to a particular period with any degree of confidence. Many older scholars classed it or even printed it with the Orphic Hymns, which are transmitted together with the Homeric Hymns as well as with the hymns of Callimachus and Proclus. But the similarity with the Orphic (...) Hymns is only superficial. It merely consists in the stylistic feature of accumulated epithets, a common characteristic of late hymns. There are three reasons for not lumping the Hymn to Ares with the very homogeneous Orphic series. First, the Orphic Hymns are courteous invocations of different gods to come to a ceremony described as τєλєτή or τєλєτταί, while the Hymn to Ares is an intensely personal prayer for the poet's own soul. Secondly, the Orphic collection already contains a hymn to Ares, and duplications are avoided. Thirdly, in the Homeric hymn Ares is addressed as a planetary god. In the Orphic hymn to Ares, this aspect is totally absent, and the same is true of the hymns to Hermes, Aphrodite, Zeus, and Kronos. (shrink)

City archives, mined by Aristotle for his Didaskaliai, preserved a reasonably complete record of dramatic productions in the fifth century. But how far back did these archives go? The so-called Fasti, an inscription set up c. 346 and listing dithyrambic, comic and tragic victors year by year, must have been based on the same archives, but went back, it is thought, only as far as 502/1. Its heading πρ]τον κμοι ἦσαν τ[ι διονσ]ωι τραγωιδο δ[, however supplemented, implies an intention of (...) going back to the beginning of things, in other words to the beginning of the archival record. This raises serious doubt as to whether that record went back to the alleged date of Thespis' première, or indeed to those given for Choerilus' and Phrynichus'. (shrink)

I shall argue for two complementary theses: firstly that ‘Homer’ was not the name of a historical poet, but a fictitious or constructed name, and secondly that for a century or more after the composition of the Iliad and Odyssey there was little interest in the identity or the person of their author or authors. This interest only arose in the last decades of the sixth century; but once it did, ‘Homer’ very quickly became an object of admiration, criticism, and (...) biographical construction. (shrink)

They used to believe that mankind began in 4004 B.C. and the Greeks in 776. We now know that these last five thousand years during which man has left written record of himself are but a minute fraction of the time he has spent developing his culture. We now understand that the evolution of human society, its laws and customs, its economics, its religious practices, its games, its languages, is a very slow process, to be measured in millennia. In the (...) case of Greek religious usage it is now appreciated that it has its roots not in Mycenaean but in Palaeolithic times. As for Greek poetry, comparative studies have shown that it goes back by a continuous tradition to Indo-European poetry. (shrink)

Several of the treatises and lectures that make up the Hippocratic corpus begin with more or less extended statements about the physical composition and operation of the world at large, and approach the study of human physiology from this angle. We see this, for example, in De Natwra Hominis, De Flatibus, De Carnibus, De Victu; it was the approach of Alcmaeon of Croton, Diogenes of Apollonia, and according to Plato of Hippocrates himself. The work known as De Hebdomadibus would appear (...) to be a prime example of the type. The first twelve chapters are cosmological. They are dominated by two ideas: that everything in nature is arranged in groups of seven, and that the human body is constructed on the same pattern as the whole world. In the later part of the book we pass to the subject of fevers, their causation and treatment. But as Roscher observed, the cosmology and the pathology do not belong together. (shrink)

‘Alcman lived sometime in the seventh century.’ ‘At some period in the seventh century Sparta was occupied with the Second Messenian War, but we do not know its date or whether Alcman lived before or during or after it.’ Between these two utterances, part of a papyrus commentary on Alcman was published,3 from which it appeared that the poet mentioned names known to us from the Spartan king-lists. It might have been expected that this discovery would lead to a more (...) precise dating for Alcman. Some people think, that in fact it does, and I am one of them. (shrink)

This important and extensive fragment of the Catalogues is preserved on a papyrus of the third century A.D., no. 10560 in the Berlin collection. First published in 1907 by Schubart and Wilamowitz, Berliner Klassikertexte, v. 1. 31 ff. , it was also collated by Crönert, who published his readings in Hermes xlii , 610 ff. The most recent edition is that of Merkelbach, Die Hesiod-fragmente auf Papyrus , pp. 24 ff. The photograph mentioned above is the only one published. It (...) covers only a small portion of the text; most of the rest is too faint to be suitable for photography. (shrink)

Each of the Orphic Hymns is headed in the manuscripts by the name of the deity to which it is addressed, and in most cases a specification of the kind of incense to be used: thus 2 Only the first hymn lacks a heading. It is preceded in the manuscripts by a poem in which Orpheus addresses Musaeus and teaches him a prayer to a multitude of gods.

The third volume in West's Hellenica trilogy is devoted to philosophy, and music and metre; however, it also contains essays on other literary texts and topics.

In CQ 20 , 277–87, 1 argued for dating Corinna to the third century B.C. In my Greek Metre , p. 141, I continued to assume this date, observing that not everyone accepted it but that I knew of no attempt to answer my arguments. I must confess to having overlooked at least one such attempt, by A. Allen in CJ 68 , 26–8; and now M. Davies has mounted another in SIFC 81 , 186–94, largely repeating Allen's points but (...) with some new touches. Allen upholds the traditional fifth-century date. Davies has yet to come to a decision, but meanwhile he is eager to discredit what he regards as an unsatisfactory case for a Hellenistic dating. (shrink)

It is well known that sometime before 700 b.c. the Greeks took over from the Near East a complex theogonic myth about the succession of rulers in heaven, involving the motifs of the castration of Sky and a swallowing and regurgitation by his successor, and that this story forms the framework of Hesiod's Theogony. It is less well known that at a later epoch, sometime before the middle of the sixth century b.c., a quite different and no less striking oriental (...) myth about the beginning of things was introduced to Greece: the myth of the god Unaging Time, who created the materials for the world from his own seed, and of the cosmic egg out of which the heaven and the earth were formed. I have discussed this myth and its variants elsewhere. My purpose in re-examining it here is firstly to clarify various details of the Phoenician versions of the cosmogony as reported in Greek sources, secondly to obtain a sharper picture of its original form, and thirdly to argue that the world model of the early Ionian philosophers, which to some extent set the pattern for subsequent Greek cosmology, owed more to the myth than has generally been appreciated.

In the controversy over the date of Corinna, the following points may be taken as agreed: 1. An edition was made in Boeotia about the end of the third or beginning of the second century B.C. 2. The texts of Corinna current in the late Hellenistic and Roman periods were all descended from that Boeotian edition. 3. Before its dissemination, Corinna was unknown in Greece at large. If she wrote at an earlier period, she must have been remembered only locally. (...) The difference between Boeotian spelling of the fifth century and that of the fourth is very great: but the difference in this respect between the mid-fourth century and the late third or early second is comparatively slight. It is therefore tenable that whereas there would be a good reason for the re-spelling of fifth-century Boeotian into the later convention of any period, there would be no obvious or adequate reason for re-spelling Boeotian of the fourth century into the orthography of the third, or that of the third into that of the second. Even those features of fourth-century spelling which have ceased to preponderate are by no means unknown or even uncommon at the end of the third century. (shrink)

CRISPR, a recently developed gene-editing tool, has become synonymous with rapid biological advancement. While gene editing had been performed in life sciences research for decades, genetic engineering with CRISPR is much more straightforward, faster, and less expensive—and thus, the technology has been rapidly democratized. CRISPR was built on a natural mechanism, the method by which bacteria resist infections from viruses called bacteriophage. Once infected, bacteria may recognize specific genetic sequences of the invading bacteriophage virus and chop its genetic material into (...) pieces. This bacterial immune response, discovered through basic research, has been exploited by scientists to develop a gene-editing tool... (shrink)
