Attention to memory: orienting attention to sound object representations

Despite a growing acceptance that attention and memory interact, and that attention can be focused on an active internal mental representation (i.e., reflective attention), there has been a paucity of work focusing on reflective attention to ‘sound objects’ (i.e., mental representations of actual sound sources in the environment). Further research on the dynamic interactions between auditory attention and memory, as well as its degree of neuroplasticity, is important for understanding how sound objects are represented, maintained, and accessed in the brain. This knowledge can then guide the development of training programs to help individuals with attention and memory problems. This review article focuses on attention to memory with an emphasis on behavioral and neuroimaging studies that have begun to explore the mechanisms that mediate reflective attentional orienting in vision and more recently, in audition. Reflective attention refers to situations in which attention is oriented toward internal representations rather than focused on external stimuli. We propose four general principles underlying attention to short-term memory. Furthermore, we suggest that mechanisms involved in orienting attention to visual object representations may also apply for orienting attention to sound object representations.     

Metaphor as Argument: Rhetorical and Epistemic Advantages of Extended Metaphors

This paper examines from a cognitive perspective the rhetorical and epistemic advantages that can be gained from the use of (extended) metaphors in political discourse. We defend the assumption that extended metaphors can be argumentatively exploited, and provide two arguments in support of the claim. First, considering that each instantiation of the metaphorical mapping in the text may function as a confirmation of the overall relevance of the main core mapping, we argue that extended metaphors carry self-validating claims that increase the chances of their content being accepted. Second, we show how the recognition of an extended metaphor’s sophistication and relevance (on behalf of the addressee) can benefit the speaker’s perceived competence (ethos). We then assess whether these two arguments measure against the dual epistemic monitoring postulated in the notion of epistemic vigilance (i.e., assessment of the source of a message and assessment of the message) and conclude that extended metaphors may fulfil the requirements of epistemic vigilance and lead to the stabilisation of a belief. We illustrate our account with an analysis of the extended metaphor of the USA as an empire found in a political pamphlet written by the Swiss politician Oskar Freysinger.     

Psychoanalysis and psychoanalysts in France between 1939 and 1945

France was affected by a deep psychoanalytic silence, both in theoretical and clinical fields, throughout the four years of German occupation. The psychoanalytic Institute closed its doors and the Revue française de Psychanalyse interrupted its publication as soon as the armistice was declared in 1940. Some people, e.g. Rudolf Loewenstein or Princess Marie Bonaparte emigrated, others fought, for instance, Sacha Nacht or Paul Schiff. Daniel Lagache went on with his researches under the auspices of the University of Strasbourg which had sought shelter in Clermont-Ferrand. René Laforgue cooperated with the German occupier; after the Liberation of France in 1944 he was discarded from a group in which, a few years before, he may have entertained the hope of playing an outstanding role. Quite a few of those he analysed remained faithful to him - which was to have an important bearing on the evolution of the psychoanalytic movement in France after 1945. In 1945, indeed, the new generation emerging from the last convulsions of the war, were to gather around the most influential potential leaders: Sacha Nacht and Jacques Lacan. Only after the latency of those silent years, only after those years of violent struggles and cowardice, would the psychoanalytic elaboration appear, along with the institutional feuds to which they gave rise - in a conflictual climate amounting to the scission of 1953.     

Images of freud: From his correspondence

Abstract

The study of the epistolary activity of Freud, because of the specific investment demonstrated by the estimated 20,000 letters which make up his correspondence, in itself affords us various insights: on Freud himself, describing himself from day to day, on the history and nature of the conscious and unconscious libidinal relationships which linked him to his principal correspondents and, taking this exceptional case as our starting point, on the specificity of the need to write and to receive letters which is present to differing degrees in every human being. Leaving to others the detailed investigation of the content of this correspondence as a source of biographical or theoretical information, this work concentrates on the comments by Freud himself on the many different aspects of the art of the letter-writer. The method used was specific: some 600 extracts from his letters were read, whereby we confined ourselves to remarks on the material circumstances in which they were written, the handwriting, the detailed records which were kept of them, their frequency, their family or conventional aspects, etc. This intentionally limited vision allows us to isolate a number of points of reference in the manifestations of a compulsion to write intended to prevent the occurrence, already feared by the young Freud of age 18 years, of “mortal boredom”.     

Discrete Visual Samples May Control Locomotor Equilibrium and Foot Positioning in Man

The static or dynamic visual cues required for equilibrium as well as for foot guidance in visually guided locomotion in man were studied using a variety of locomotion supports and illumination and visual conditions. Stroboscopic illumination (brief flashes) and intermittent lighting (longer flashes) were used to control and to vary the visual sampling frequency of static (positional/orientational) visual cues. There were three main findings: First, visual control of foot positioning during locomotion over discontinuous terrain depends mainly upon static visual cues with a low sampling frequency (about 3 Hz); second, visual control of dynamic equilibrium during locomotion over a narrow support depends mainly upon the availability of high frequency static visual cues (up to about 12 Hz); and third, static visual cues required for equilibrium control are extracted from both the peripheral and the central visual field.

Assuming that discrete demands for feedback occur, a simple probabilistic model was proposed, according to which the mean time that elapses following presentation of static visual cues about positions or changes of position accounts for the differences in the difficulty of the various illumination conditions.     

Stereotype threat undermines intellectual performance by triggering a disruptive mental load

Research on stereotype threat has repeatedly demonstrated that the intellectual performance of social groups is particularly sensitive to the situational context in which tests are usually administered. In the present experiment, an adaptation of the Raven Advanced Progressive Matrices Test was introduced as a measure of cognitive ability. Results showed that individuals targeted by a reputation of intellectual inferiority scored lower on the test than did other people. However, when the identical test was not presented as a measure of cognitive ability, the achievement gap between the target and the control group disappeared. Using heart rate variability indices to assess mental workload, our findings showed that the situational salience of a reputation of lower ability undermined intellectual performance by triggering a disruptive mental load. Our results indicate that group differences in cognitive ability scores can reflect different situational burdens and not necessarily actual differences in cognitive ability.     

The impact of need for closure on conservative beliefs and racism: differential mediation by authoritarian submission and authoritarian dominance

The present study explores the influence of need for closure as well as authoritarian submission (Right-Wing Authoritarianism [RWA]) and authoritarian dominance (Social Dominance Orientation [SDO]) on the genesis of conservative beliefs and racism. For this purpose, two structural equation models were compared. In Model 1, RWA and SDO were entered as independent variables and the need for closure facets Decisiveness and Need for Simple Structure acted as mediator variables. In Model 2, the need for closure facets served as independent variables and RWA and SDO acted as mediators. In two student samples (Sample 1, N = 399, Sample 2, N = 330) and one adult sample (Sample 3, N = 379), Model 2 showed superior fit to the data. These results corroborate the hypothesis that authoritarianism should be interpreted in terms of generalized beliefs rather than in terms of personality characteristics. In addition, analyses show that the effects of Need for Simple Structure on conservative beliefs and racism are fully mediated by RWA but only partly by SDO. These results suggest a differential genesis of RWA and SDO.     

On the way to assess emotions in animals: do lambs (Ovis aries) evaluate an event through its suddenness, novelty, or unpredictability?

Appraisal theories provide a framework that gives insight into emotions and could allow comparisons across species. According to these theories, events are first evaluated on their suddenness, novelty, and unpredictability. The authors examined the ability of lambs (Ovis aries) to evaluate an event according to these 3 criteria through 3 tests. The lambs responded to suddenness with a startle response coupled with an increase in heart rate and to novelty with an orientation response coupled with an increase of vagal activity. There was no clear evidence that lambs can detect the predictability of an event. Those results support the usefulness of appraisal theories to assess emotion in animals.     

Protein synthesis inhibition blocks consolidation of an acrobatic motor skill

To investigate whether motor skill learning depends on de novo protein synthesis, adult rats were trained in an acrobatic locomotor task (accelerating rotarod) for 7 d. Animals were systemically injected with cycloheximide (CHX, 0.5 mg/kg, i.p.) 1 h before sessions 1 and 2 or sessions 2 and 3. Control rats received vehicle injections before sessions 1, 2, and 3. Although CHX did not affect improvement of performance within session 1, between-session improvement was impaired. In overtrained animals, comparable injections of CHX had no effect on rotarod performance. These findings suggest that consolidation of motor skills requires protein synthesis.     

The relative deprivation-gratification continuum and the attitudes of South Africans toward immigrants: a test of the V-curve hypothesis

It has long been established that there is a linear and positive relationship between relative deprivation and prejudice. However, a recent experiment suggests that the converse of relative deprivation, relative gratification, may also be associated with prejudice (S. Guimond & M. Dambrun, 2002). Specifically, the evidence suggests that the usual test for a linear relationship between relative deprivation-gratification and prejudice might conceal the existence of a bilinear relationship. This function, labeled the V-curve hypothesis, predicts that both relative deprivation and relative gratification are associated with higher levels of prejudice. This hypothesis was tested with a representative sample of South Africans (N=1,600). Results provide strong support for the V-curve hypothesis. Furthermore, strength of ethnic identification emerged as a partial mediator for the effect of relative gratification on prejudice.
