De l'argumentation comme métamorphose

Linguistic rhetoric and argumentative reasoning are generally identified. Certain types of problems, however, make use of non-verbal systems of representation, and, among them, image. Image is not just matter but also form, and computer processing in AI makes it possible to grasp this form by linguistic means (logico-mathematical languages). The synthesis of animated images has made it possible to represent metamorphoses, the thought of the unexpected. The fact that language produces image (and conversely) does not fail to transform the standard ways of thinking about epistemology.

     

Transfer of matching performance in pigeons.

Three pigeons were given extensive training on three-key simultaneous matching problems using geometric-form and hue stimuli. After acquisition of matching, the birds were tested with pairs of stimuli involving one or both novel members. Matching during the test stimuli occurred less often than during the later stages of the acquisition phase, but more often than would occur if no transfer had taken place. Greater positive transfer was observed for problems that involved one, rather than two, novel stimuli. In the second phase of the experiment, previously trained birds were shifted to problems that required symbolic matching, i.e., the pigeons had to associate a particular center-key stimulus with a particular side-key stimulus. On each trial, one of two simuli was presented on the center key, and two other stimuli, different from those used on the center key, were displayed on the side keys. When the problem shift was introduced, correct responding was impaired, but remained considerably above chance level and quickly recovered in following sessions. The results were interpreted as favoring a stimulus-response-chaining account of matching behavior.     

Covert orienting of attention in 3-month-old infants: The case of biological motion

Humans attend to different positions in the space either by moving their eyes or by moving covertly their attention. The development of covert attention occurs during the first year of life. According to Colombo’s model of attention (2001), within the first years there is a significant change in infants’ visuo-spatial orienting mechanisms, from a predominantly overt form to a covert orienting starting from 4 to 5 months of life. The use of non-invasive brain imaging techniques can shed light on the origin of such mechanisms. In particular, EEG and ERP studies can directly investigate the neural correlates of covert attention in young infants. The present study investigated the neural correlates of covert attention employing a visuo-spatial cueing paradigm in 3-month-old infants. Infants were presented with a central point-light walker (PLD) followed by a single peripheral target. The target appeared randomly at a position either congruent or incongruent with the walking direction of the cue. We examined infants’ target-locked P1 component and the saccade latencies toward the peripheral target. Results showed that the P1 component was larger in response to congruent than to incongruent targets and saccade latencies were faster for congruent rather than incongruent trials. Moreover, the facilitation in processing sensory information (priming effects) presented at the cued spatial location occurs even before the onset of the oculomotor response, suggesting that covert attention is present before 4 months of age. Overall, this study highlights how ERPs method could help researchers at investigating the neural basis of attentional mechanisms in infants.     

Attitudes Toward Affirmative Action as a Function of Racial Identity Among African American College Students

Variations in support for affirmative action were assessed in a sample of 181 African American college students in Massachusetts. These students generally endorsed affirmative action, and endorsement varied positively as a function of the belief that one had personally benefited from affirmative action. Aspects of racial identity, indexed by the Multidimensional Inventory of Black Identity, also predicted variations in attitudes toward affirmative action, over and above background factors and personal benefit. Consistent with realistic group conflict theory, the most influential aspects of identity were centrality (i.e., the degree to which group identity is central to personal identity), private regard (i.e., pride in the group), and an oppressed minority ideology (i.e., a viewpoint that emphasizes the similarities between African Americans and other oppressed groups).     

Poetics in the shadow of the other's language: The melancholic discourse of the trilingual poet Amelia Rosselli

In this paper, I propose a psychoanalytic reading of some of the writings of Amelia Rosselli, a trilingual poet who, at the age of seven, lost her father Carlo, who was persecuted and murdered by Mussolini's regime. History and her history conflate into personal and collective trauma which defies human possibilities to work through and mourn. Rosselli's work testifies to such predicament of the human subject of the 20th century, his/her dislocation, alienation and internal irreconcilable divisions. In particular I examine Diary in three tongues, which is the most autobiographical of her works and a self‐analytic piece, written after the conclusion of her second analysis. In the Diary, Rosselli employs textual strategies which convey the fragmentation and destructuring of language, where her traumatic experience resides as a wound inflicted to the symbolic order. I propose that her writings contain her unconscious memories in an estranged and melancholic language which becomes the crucible to express her impossible mourning, in a complex mixture of Eros and Thanatos which allowed her to survive psychically and to create a very personal experimental poetic discourse which made her a literary figure of international acclaim. My primary engagement will be with Freud's theory of mourning and melancholia and its successive elaboration by Kristeva, who maintains that the melancholic discourse finds its expression in the pre‐verbal and infra‐verbal aspects of language, which she calls ‘semiotics’, in dialectic articulation with its symbolic components. Drawing on literary texts, significant inferences can be made on the psychoanalytic listening to the prosodic aspects of language as the carrier of inchoate forms of representation of that which exceeds language: trauma, raw affects, mnemic traces, that is, the unrepresented and/or unrepresentable.     

Investigating the role of response in spatial context learning

Recent research has shown that simple motor actions, such as pointing or grasping, can modulate the way we perceive and attend to our visual environment. Here we examine the role of action in spatial context learning. Previous studies using keyboard responses have revealed that people are faster locating a target on repeated visual search displays (“contextual cueing”). However, this learning appears to depend on the task and response requirements. In Experiment 1, participants searched for a T-target among L-distractors and responded either by pressing a key or by touching the screen. Comparable contextual cueing was found in both response modes. Moreover, learning transferred between keyboard and touch screen responses. Experiment 2 showed that learning occurred even for repeated displays that required no response, and this learning was as strong as learning for displays that required a response. Learning on no-response trials cannot be accounted for by oculomotor responses, as learning was observed when eye movements were discouraged (Experiment 3). We suggest that spatial context learning is abstracted from motor actions.     

Preschoolers prior formal mathematics education engage numerical magnitude representation rather than counting principles in symbolic ±1 arithmetic: Evidence from the operational momentum effect

In numerical cognition research, the operational momentum (OM) phenomenon (tendency to overestimate the results of addition and/or binding addition to the right side and underestimating subtraction and/or binding it to the left side) can help illuminate the most basic representations and processes of mental arithmetic and their development. This study is the first to demonstrate OM in symbolic arithmetic in preschoolers. It was modeled on Haman and Lipowska's (2021) non-symbolic arithmetic task, using Arabic numerals instead of visual sets. Seventy-seven children (4–7 years old) who know Arabic numerals and counting principles (CP), but without prior school math education, solved addition and subtraction problems presented as videos with one as the second operand. In principle, such problems may be difficult when involving a non-symbolic approximate number processing system, whereas in symbolic format they can be solved based solely on the successor/predecessor functions and knowledge of numerical orders, without reference to representation of numerical magnitudes. Nevertheless, participants made systematic errors, in particular, overestimating results of addition in line with the typical OM tendency. Moreover, subtraction and addition induced longer response times when primed with left- and right-directed movement, respectively, which corresponds to the reversed spatial form of OM. These results largely replicate those of non-symbolic task and show that children at early stages of mastering symbolic arithmetic may rely on numerical magnitude processing and spatial-numerical associations rather than newly-mastered CP and the concept of an exact number.     

Archetypes as symbolic forms

In Jung's psychology, archetypes are biologically inherited supra-individual predispositions of the collective unconscious, and in this paper this controversial theory of archetypes is evaluated in the context of Ernst Cassirer's philosophy of symbolic forms. The main thesis of the author is that with the help of the Cassirerian approach, archetypes can be understood as culturally determined functionary forms organizing and structuring certain aspects of man's cultural activity, namely those predominantly non-cognitive (for example, emotional, numinous, pathological) mental aspects of human life, which remain more or less unarticulated due to their non-discursive nature. The revision the author is proposing revolves around the notion that the archetypal theory can be removed from the rather unfruitful discourse on the genetic inheritance of archetypes. When archetypes are seen as symbolic forms, Jung's theory is in a position to make a potentially valuable contribution to hermeneutical and cultural studies, as archetypes function in this new context as active constituents of human experiences, which give these experiences a non-discursive, symbolic form. Thereby, archetypes can become accessible to historical and cultural analyses, and hermeneutical inquiry into the manifold symbolism of mental (including unconscious) phenomena can be enriched.     

On the origins of naming and other symbolic behavior

We identify naming as the basic unit of verbal behavior, describe the conditions under which it is learned, and outline its crucial role in the development of stimulus classes and, hence, of symbolic behavior. Drawing upon B. F. Skinner's functional analysis and the theoretical work of G. H. Mead and L. S. Vygotsky, we chart how a child, through learning listener behavior and then echoic responding, learns bidirectional relations between classes of objects or events and his or her own speaker-listener behavior, thus acquiring naming-a higher order behavioral relation. Once established, the bidirectionality incorporated in naming extends across behavior classes such as those identified by Skinner as the mand, tact, and intraverbal so that each becomes a variant of the name relation. We indicate how our account informs the specification of rule-governed behavior and provides the basis for an experimental analysis of symbolic behavior. Furthermore, because naming is both evoked by, and itself evokes, classes of events it brings about new or emergent behavior such as that reported in studies of stimulus equivalence. This account is supported by data from a wide range of match-to-sample studies that also provide evidence that stimulus equivalence in humans is not a unitary phenomenon but the outcome of a number of different types of naming behavior.
