AbstractNewly learned information undergoes a process of awake reactivation shortly after the learning offset and we recently demonstrated that this effect can be observed as early as area V1. However, reactivating all experiences can be wasteful and unnecessary, especially for familiar stimuli. Therefore, here we tested whether awake reactivation occurs differentially for new and familiar stimuli. Subjects completed a brief visual task on a stimulus that was either novel or highly familiar due to extensive prior training on it. Replicating our previous results, we found that awake reactivation occurred in V1 for the novel stimulus. On the other hand, brief exposure to the familiar stimulus led to ‘awake suppression’ such that neural activity patterns immediately after exposure to the familiar stimulus diverged from the patterns associated with that stimulus. Further, awake reactivation was observed selectively in V1, whereas awake suppression had similar strength across areas V1–V3. These results are consistent with the presence of a competition between local awake reactivation and top-down awake suppression, with suppression becoming dominant for familiar stimuli.

This paper discusses the theory advanced by Bakhtin about dialogism and methodological concepts. This theory to formulate the concept of human existence on the other, which is based on the idea that humans judge him from the viewpoint of others. Humans understand the moments of consciousness and take it into account through the eyes of others. According to this theory, the essence of human life is a dialogue. The Method of heteroglossia talks about signs in the universe of individuals because of the word "heteros" means "other" or different, while "glossia" means the tongue or language. In this method mentioned that people are saying needs to be heard, and the author also has the same rights that words need to be heard. A word is born from dialogue to address the problems of life. On the other hand, Bakhtin sees carnival method has spawned a new literary genre, the polyphonic novel. The polyphonic novel is a novel that is characterized by a plurality of voice or consciousness, and the voices or the overall awareness dialogical. Polyphonic essentially a "new theory of authorial viewpoint". Polyphonic appear in fiction when the position of the author freely allowed to interact with the characters. The characters in the novel are freely polyphonic appear to argue with each other and even with the author.

The aim of this article is to trace the referential value of juffrouw Lina (1888)as part of its narrative organisation by means of the narrativist historical theoryof Frank Ankersmit. This starting point demands a confrontation of thisnaturalist novel by Marcellus Emants with the contemporary medical biographyof the French writer and politician Chateaubriand by the Belgian physicianErnest Masoin on the one hand and with some case studies of hystericsby the famous French docter Jean-Martin Charcot on the other hand. lt willbe argued that the narrativity of the novel plays a key-role in the constructionof its referential value on various levels.

The paper examines two key novels by Sandro Veronesi, the modern Italian writer, Calm Chaos (2006) and Colibri (2020). Both novels were awarded Italy’s main literary prize, the Premio Strega, which is a unique precedent. The relevance of the article comes from the high demand for research on contemporary Italian literature on the one hand and from the novelty of the proposed interpretation for the novel Calm Chaos on the other hand. For the first time, the protagonist of Calm Chaos, Pietro Palladini, is presented not as a preacher of eternal values, returning the reader to the theme of knowing oneself and the surrounding world, but as a mad visionary with clear signs of psychopathy and schizophrenia. The analysis of Veronesi’s latest novel Colibri reveals the character’s evolution and the writer’s narrative manner. The theme of psychiatry in the life of a modern person appears to be one of the key ones in Veronesi’s work.

The novel presents a variety of characters, each has his own journey. Since the novel puts forth the time of partition (Indo- Bangladesh) and time after it, characters can be seen with traits which are both traditional and modern. It is due to their upbringing and values that their mind has certain inclinations. Because of her traditional values Thamma shows repulsion towards Ila and Tridib. The later ones on the other hand has their own personal set of beliefs to live their lives. Such disparity in thoughts gives a hint of clashes between them in many parts of the novel. However, even the traditional characters carry a spirit of freedom and modernity within them. Also modern characters have an urge to cling to their roots too.

Abstract Subjective experience can be influenced by top-down factors, such as expectations and stimulus relevance. Recently, it has been shown that expectations can enhance the likelihood that a stimulus is consciously reported, but the neural mechanisms supporting this enhancement are still unclear. We manipulated stimulus expectations within the attentional blink (AB) paradigm using letters and combined visual psychophysics with magnetoencephalographic (MEG) recordings to investigate whether prior expectations may enhance conscious access by sharpening stimulus-specific neural representations. We further explored how stimulus-specific neural activity patterns are affected by the factors expectation, stimulus relevance and conscious report. First, we show that valid expectations about the identity of an upcoming stimulus increase the likelihood that it is consciously reported. Second, using a series of multivariate decoding analyses, we show that the identity of letters presented in and out of the AB can be reliably decoded from MEG data. Third, we show that early sensory stimulus-specific neural representations are similar for reported and missed target letters in the AB task (active report required) and an oddball task in which the letter was clearly presented but its identity was task-irrelevant. However, later sustained and stable stimulus-specific representations were uniquely observed when target letters were consciously reported (decision-dependent signal). Fourth, we show that global pre-stimulus neural activity biased perceptual decisions for a ‘seen’ response. Fifth and last, no evidence was obtained for the sharpening of sensory representations by top-down expectations. We discuss these findings in light of emerging models of perception and conscious report highlighting the role of expectations and stimulus relevance.

The selectivity and obliquity of Arthur Hopkins's illustrations for the 1878 Belgravia serialization of The Return of the Native result in a distorted reading of Hardy's text, especially through their avoidance of the passionate and subversive and their tendency to represent the novel as substantially more conventional than it actually is. Hopkins's Thomasin and Venn are represented as unambiguously and conventionally "good"; there is no visual acknowledgment of the more radical Thomasin or the more threatening Venn. Wildeve is essentially avoided as a pictorial subject, as is the problematic Clym of the novel's final books. Eustacia, on the other hand, figures prominently in the illustrations, initially-in keeping with her departure from hegemonic notions of viruous femininity-as a somewhat "masculine" figure. Follwoing Hardy's insistence that she be rendered more conventionally attractive. Hopkins rather incongruously transforms her into an object of desire, only to revert in the final illustration to his less than sympathetic reading: refusing to participate in the erotics of death of Hardy's text, Hopkins punishes the "fallen woman" by reducing her to a misshapen corpse. Hardy's essential toleration-and in some instances actual encouragement-of what now seem "unrepresentative" representations of his work appears to have been related to his own anxiety about the novel's success and based on the recognition that the very conventionality of the illustrations could be a valuable ally in his struggle to render publishable a text that pushed persistently against the limits of the then acceptable.

In this experiment with a Novel Label Task, 48 children ages 5 to 6 years were given a novel word for a target item, e.g., a dog. They were also given one of two types of featural information for the target item, a feature naturally common to animals, i.e., “This has a heart inside,” or an accidental feature uncommon to animals, i.e., “This gets a splinter.” As a result, the number of children who interpreted the novel word at the superordinate level (animal) increased significantly when they were given the feature naturally common to animals. On the other hand, there was no significant increase for an accidental feature. Further, the children were given the instruction that all animal items in this task had the same featutes as the target item. As a result, although the number of children who interpreted the novel word at the superordinate level (animal) increased significantly when they were given both the feature naturally common to animals and also the accidental feature, there were more when the instruction was with the feature naturally common to animals than with the accidental feature. The findings were discussed in relation to the factors corresponding to young children's interpretation of a novel word at the superordinate level.

Simple structural analysis applied to passages cited from the works of André Breton elucidates the reasons for his condemnation of the statement La marquise sortit à cinq heures (see his Manifeste du surréalisme, 1924) as non-poetic. This study demonstrates the opposition existing between the above-mentioned realist sentence, essentially non-subjective (third-person subject), non-actual (past tense predicate), contextual (context can be supposed), and prosaic (lack of imagery), and on the other hand a theoretic surrealist sentence, essentially subjective (first-person subject), actual (present tense predicate), and non-contextual, producing a shock-image. In reality, Breton's surrealistic phrase does not always contain all of these qualities at once. However, in contrast to the condemned phrase which contains none at all, it does always manifest at least one of these characteristics, the most important having reference to the evocative power of the shock-image. A final comparison with a sentence quoted from Robbe-Grillet, the theoretician of the “nouveau roman”, proves that even though it may appear objective, the surrealist phrase is really not so. In conclusion, the four characteristics of the ideal surrealist sentence—subjectivity, actuality, non-contextuality, and ability to produce shock-images—create a poetics of discontinuity opposed to the classical art of narration as found traditionally in the novel.

2-Arylidenebenzosuberones react with a Wittig-Horner reagent in the presence of sodium hydride as a base to give the novel dimethyl (4-(4-methoxyphenyl)-2-oxa-2,3,4,5,6,7-hexahydrobenzo- [6,7]cyclohepta[1,2-b]pyran-3-yl)phosphonate. On the other hand, 6,7-dihydrobenzo[6,7]cyclohepta- [1,2-b]pyran-2(5H)-ones were isolated from the reaction of 2-arylidenebenzosuberones withWittig- Horner reagents using alcoholic sodium alkoxide. The reaction of 2-arylidenebenzosuberones with trialkyl phosphites affords the alkyl phosphonate derivatives. Tris(dialkylamino)phosphines react with 2-arylidenebenzosuberones to give the oxaphospholanoxide products. 2-Arylidenebenzosuberones react with Lawesson’s reagent to yield the corresponding dimers. Some of the prepared products were screened for antitumor activity

The article discusses the image of Tel Aviv, the first Hebrew city, as it is described in the novelPreliminariesby S. Yizhar (Yizhar Smilansky), one of Israel's best-known authors. In this novel, which engages with the question of home and borders, borders function as a double-edged sword: on the one hand, they define home and create a circumscribed place for the protagonist and his family. On the other hand, the novel dwells on the urge to cross borders and shatter the distinction between home and the world. In this regard, Tel Aviv is sometimes described as a pleasant, “normal” city, yet at other times it is written as a perilous place—since it divides between Jews and Arabs. Tel Aviv is also the place where one can imagine a great future or see a concealed history. It is a total urban experience, encapsulating the individual.
