Processing of representations in declarative and procedural working memory

The article investigates the relation between declarative and procedural working memory (WM; Oberauer, 2009). Two experiments test the assumption that representations in the two subsystems are selected for processing in analogous ways. Participants carried out a series of decisions on memorized lists of digits. For each decision, they had to select declarative and procedural representations. Regarding declarative representations, participants selected a memory set and a digit within this set as the input to each decision. With respect to the procedural representations, they selected a task set to be applied to the selected digit and a response within that task set. We independently manipulated the number of lists and the number of tasks to be switched among (one, two, or three; Experiment 1) and preparation time for a list switch (Experiment 2). For three effects commonly observed in task-switch studies, analogues in declarative WM were found: list-switch costs, mixing costs, and residual switch costs. List- and task-switch costs were underadditive, suggesting that declarative and procedural representations are selected separately and in parallel. The findings support the hypothesis of two analogous WM subsystems.     

‘Battling with the unlaid ghost’: psychotherapy with a child traumatised in infancy

This paper attempts to explore the nature and consequences of early trauma on the mental development of a 9-year-old boy I have called Luke. The traumatic event occurred within the context of a more chronic and ongoing trauma, which was due to the lack of receptive and containing parental figures. The combination of these two kinds of traumatic experiences had a destructive impact on the making of Luke's internal world and greatly disrupted the development of his capacity for thought. I will specifically refer to the theory of trauma and to Bion's theory of thinking in order to illustrate the crucial link between trauma and mental work and the complex challenge it brings. I will describe how, during the course of 2 years of intensive treatment, Luke gradually became able to restore his capacity for mental functioning, which made it possible for him to begin to think about and make sense of his extreme emotional experiences.

Dans cet article, l'auteur cherche à explorer la nature et les conséquences, pour le développement psychique d'un garçon de neuf ans qu'il appelle Luke, d'un traumatisme précoce. L'événement traumatique s'est produit dans le contexte d'une situation traumatique plus chronique et plus globale en raison de l'absence de figures parentales réceptives et contenantes. L'association de ces deux types de vécu traumatique, avec leur impact destructeur sur la construction du monde interne de Luke, a créé des perturbations majeures du développement de sa capacité à penser. L'auteur se réfère tout particulièrement à la théorie du traumatisme ainsi qu'à la théorie de l'activité de pensée de W. R. Bion afin d'illustrer le lien fondamental qui existe entre traumatisme et travail psychique, ainsi que le défi complexe que ce travail doit confronter. L'auteur montre qu'au cours de deux années de traitement intensif Luke a progressivement retrouvé ses capacités de fonctionnement psychique, de sorte qu'il a pu commencer à réfléchir à ses vécus émotionnels insoutenables et réussir à y comprendre quelque chose.

Riassunto: In questo articolo si cerca di esplorare la natura e le conseguenze del trauma precoce sullo sviluppo mentale di un bambino di nove anni che chiamerò Luca. L'evento traumatico accadde all'interno di un contesto di trauma pi[ugrave] cronico e duraturo dovuto all'assenza di figure parentali recettive e contenitive. La combinazione di questi due tipi di esperienze traumatiche ebbe un impatto distruttivo sul mondo interno di Luca e interferì enormemente con lo sviluppo della sua capacità di pensare. Farò principalmente riferimento alla teoria del trauma e alla teoria del pensiero di Bion per illustrare il legame particolare tra trauma e lavoro mentale e la complessa sfida che ne consegue. Descriverò come durante il lavoro intensivo di due anni, Luca divenne gradualmente capace di recuperare la sua capacità di funzionamento mentale che gli permise di incominciare a pensare e dare un senso alle sue esperienze emotive estreme.

Der Artikel versucht, die Eigenschaften und Konsequenzen von frühem Trauma auf die psychische Entwicklung eines 9-jährigen Jungens, den ich Luke nenne, zu betrachten Das traumatische Ereignis passierte im Umfeld eines mehr chronischen und fortdauernden Traumas, wegen Mangel an rezeptiven und haltenden elterlichen Figuren. Die Kombination dieser zwei Arten von Trauma hatte eine destruktive Auswirkung auf das Entstehen von Lukes innerer Welt und störte erheblich die Entwicklung seiner Denkfähigkeit. Ich werden mich speziell auf Traumatheorie und auf Bion's Theorie des Denkens beziehen, um die entscheidende Verbindung zwischen Trauma und mentaler Arbeit und der komplexen Herausforderung, die das mit sich bringt, zu illustrieren. Ich werde beschreiben, wie Luke allmählich im Laufe einer zwei-jährigen intensiven Behandlung in der Lage war, seine Fähigkeit für mentales Funktionieren wiederherzustellen, was es ihm ermöglichte anzufangen, über seine extremen emotionalen Erfahrungen nachzudenken und Sinn herzustellen

The body one has and the body one is: Understanding the transsexual’s need to be seen

The transsexual individual confronts the analyst with a disturbing otherness. How this otherness is understood, that is, how the analyst ‘looks’ at the patient through her distinctive theoretical lens impacts, in turn, on the patient’s experience and what transpires between them. In this paper the author outlines a developmental model rooted in attachment and object relations theory to provide one alternative way of ‘looking’ at some of these patients’ experiences in the clinical setting. It is suggested that in some cases of transsexuality the primary object(s) did not mirror and contain an early experience of incongruity between the given body and the subjective experience of gender: it remains unmentalized and disrupts self‐coherence leading to the pursuit of surgery that is anticipated to ‘guarantee’ relief from the incongruity. Through an account of work with a male to female (MtF) transsexual who underwent surgery during her five years of psychotherapy, the author explores how a focus on the transsexual’s experience of ‘being seen’, that is, of being taken in (or not) visually and mentally by the object in their state of incongruity, affords another window through which to approach the transsexual’s experience in the transference–countertransference dynamics.     

The evolution of alexia in two cases of posterior cortical atrophy

Posterior cortical atrophy (PCA) is an uncommon presentation of Alzheimer's disease (AD), characterised by prevalent anatomo-functional involvement of posterior cortical areas. Accordingly, the main clinical features at onset are disorders of high-order visual processing, such as alexia and impairments of visuo-spatial and visuo-constructional abilities. The clinical features in the early stages of disease are variable, and they have been suggested to stem from prevalent ventral or dorsal brain pathology, and/or asymmetric hemispheric involvement. With disease progression, these differences tend to blur with the increasing severity of neuropsychological dysfunction. We report two PCA patients showing different patterns of reading impairment (respectively, letter-by-letter reading and neglect dyslexia). A follow-up study suggested that the qualitative features of alexia remain distinctive with disease evolution. In addition, single photon emission tomography (SPECT) studies revealed different patterns of hypoperfusion, consistent with the alexia types. A careful reading assessment can provide important insights to the pattern of progression of the disease in patients with PCA up to the late stages of the pathology.     

Exploring urban students' constructions about school, work, race, and ethnicity

This qualitative study is an exploration of 32 urban high school students' narratives about the connection between school, work, and societal expectations of their future success related to their racial and ethnic background. The sample varied along 2 contextual dimensions: participation in a psychoeducational intervention (Tools for Tomorrow) and developmental status (i.e., half the sample were 9th-grade students and the other half were 12th-grade students). Using consensual qualitative research, the narratives revealed 3 major domains: future orientation; students' perceptions of society's expectations based on race and ethnicity; and students' perception of the role of their race and ethnicity in future success. Results reveal that the majority of students endorse a connection between school and work, believe that society holds low expectations for them based on their racial and ethnic background, and cannot predict their future success based on their background.     

Migration Flows and Quality of Life in a Metropolitan Area: the Case of Barcelona-Spain

The phenomenon of human migration is certainly not new and it has been studied from a variety of perspectives. Yet, the attention on human migration and its determinant has not been fading over time as confirmed by recent contributions (see for instance Cushing and Poot 2004 and Rebhun and Raveh 2006). In this paper we combine the recent theoretical contributions by Douglas (1997) and Wall (2001) with the methodological advancements of Guimarães et al. (2000, 2003) to model inter-municipal migration flows in the Barcelona area. In order to do that, we employ two different types of count models, i.e. the Poisson and negative binomial and compare the estimations obtained. Our results show that, even after controlling for the traditional migration factors, QoL (measured with a Composite Index which includes numerous aspects and also using a list of individual variables) is an important determinant of short distance migration movements in the Barcelona area.     

Consequences of brain tumour resection on emotion recognition

Emotion processing impairments are common in patients undergoing brain surgery for fronto-temporal tumour resection, with potential consequences on social interactions. However, evidence is controversial concerning side and site of lesions causing such deficits. This study investigates visual and auditory emotion recognition in brain tumour patients with the aim of clarifying which lesion sites are related to impairments in emotion processing from different modalities. Thirty-four patients were evaluated, before and after surgery, on facial expression and emotional prosody recognition; voxel-based lesion–symptom mapping (VLSM) analyses were performed on patients’ post-surgery MRI images. Results showed that patients’ performance decreased after surgery in both visual and auditory modalities, but, in general, recovered 3 months after surgery. In facial expression recognition, left brain-damaged patients showed greater post-surgery deterioration than right brain-damaged ones, whose performance specifically decreased for sadness and fear. VLSM analysis revealed two segregated areas in the left hemisphere accounting for post-surgery scores for happy (fronto-temporo-insular region) and surprised (middle frontal gyrus and inferior fronto-occipital fasciculus) facial expressions. Our findings demonstrate that surgical removal of tumours in the fronto-temporal region produces impairment in facial emotion recognition with an overall recovery at 3 months, suggesting a partially different representation of positive and negative emotions in the left and right hemispheres for visually – but not auditory – presented emotions; moreover, we show that deficits in specific expression recognition are associated with discrete lesion locations.
