The effect of bilingualism on lexical learning and memory across two language modalities: some evidence for a domain-specific,but not general,advantage

ABSTRACT

The present study was conducted to replicate bilingual advantages in short-term memory for language-like material and word learning in young adults and extend this research to the sign domain, ultimately with the goal of investigating the domain specificity of bilingual advantages in cognition. Data from 112 monolingual hearing non-signers and 78 bilingual hearing non-signers were analysed for this study. Participants completed a battery of tasks assessing sign and word learning, short-term memory, working memory capacity, intelligence, and a language and demographic questionnaire. Overall, the results of this study suggested a bilingual advantage in memory for speech-like material – no other advantage (or disadvantage) was found. Results are discussed within the context of recent large-scale experimental and meta-analytic studies that have failed to find bilingual advantages in domain-general abilities such as attention control and working memory capacity in young adults.

Anaesthesia or psychotherapy: Eradicating thoughts or working them through

The author presents two sessions from the analysis of a depressive narcissistic doctor, which are characterised by a mixture of co-operation and pseudo-co-operation. The dialogue is in parts intellectualised, complicated, lifeless and schizoid. Points at which the patient shows surprising insights are then partly denigrated by him, on the basis that change is not to be expected. Semi-lifeless contact assists the defensive claustrophobia that he experiences in meaningful contact. It becomes very clear that he is then afraid of entering into an openly aggressive conflict that entails the existential threat of object loss. However, this has so far been avoided. The secret pleasure in an anal-narcissistic, sadomasochistic addiction to doubt persists in the partial denigration. The patient's artificially maintained self-doubt and doubt of the object reinforce a genuine confusion that consists in never knowing exactly what lies behind the helpful and needed object.     

Executive functions predict conceptual learning of science

We examined the relationship between executive functions and both factual and conceptual learning of science, specifically chemistry, in early adolescence. Sixty‐three pupils in their second year of secondary school (aged 12–13 years) participated. Pupils completed tasks of working memory (Spatial Working Memory), inhibition (Stop‐Signal), attention set‐shifting (ID/ED), and planning (Stockings of Cambridge), from the CANTAB. They also participated in a chemistry teaching session, practical, and assessment on the topic of acids and alkalis designed specifically for this study. Executive function data were related to (1) the chemistry assessment which included aspects of factual and conceptual learning and (2) a recent school science exam. Correlational analyses between executive functions and both the chemistry assessment and science grades revealed that science achievements were significantly correlated with working memory. Linear regression analysis revealed that visuospatial working memory ability was predictive of chemistry performance. Interestingly, this relationship was observed solely in relation to the conceptual learning condition of the assessment highlighting the role of executive functions in understanding and applying knowledge about what is learned within science teaching.     

Do goal cue and motor activity impact preschoolers’ working memory?

Preschoolers are well known for their poor working memory (WM) performance. This could result from goal neglect, which would hamper the setting of maintenance strategies. Previous studies have shown that preschoolers’ WM performance can be improved in game-like tasks, because they provide cues to support goal maintenance. However, in these studies, it was unclear what features of the task (either the main toy or the motor activity required by the game) provide efficient cues. The aim of the present study was to disentangle the two features to examine cue effects in 5- to 7-year-old children. No improvement of WM performance was observed when the toy was a potential goal cue, whereas the motor activity had a detrimental effect in all age groups. The latter effect could result from a distraction of attention from attention-based maintenance activities. Hence, preschoolers' poor WM performance would not be fundamentally due to goal neglect.     

Psychology of Science/Theology of Science: Reaching Out or Narrowing?

Formalizing a “psychology of science” today will constrain intellectual freedom in ways more likely stultifying than liberating. We should be more improvisational in seeking ideas from academic psychology to develop a more comprehensive purview. I suggest that a psychology of science should look at systematic theology and empirical theology. Liberal theologians have long experience trying to distill from religion those structural aspects that affirm openness in a search for truth. Science, as well as religion, has its myths and rituals, but theologians are more experienced than scientists at a large mythohistorical scale. There are distortions in the extreme degree to which psychological science has traditionally emphasized empiricism, positivism, hypothesis testing, and falsifiability. I argue for less critical reduction and more creative augmentation. This could include looking outside academia at cognitive competencies of people in trades. Exaggerated parsimony is an old story. This is illustrated by the opposition to David Hartley's 1749 theory of neural oscillations. There is an inexorable “margin of uncertainty” where scientific prediction and control can never outstrip the new uses to which human beings put ideas. Facts and values interact in this margin; theology has long made a home there, but scientists sometimes have been excessive in rejecting the “naturalistic fallacy.” There is also often a degree of disingenuousness in psychology's reluctance to take subjective phenomena seriously; here there may be lessons in how empirical theology has handled subjectivity, as well as in taking an honest look at the way much of the methodology of experimental psychology incorporates subjective assessments. Feist's book is a start, but these things need more thought before codifying a psychology of science.     

Individual Differences in Spatial Memory and Striatal ChAT Activity among Young and Aged Rats

Individual differences in spatial memory among young and aged rats were assessed using memory tasks related to integrity of the hippocampus and the neostriatum. Relationships were then examined between measures of spatial memory and regional choline acetyltransferase (ChAT) activity, a marker for cholinergic integrity. Twenty-four-month-old Long-Evans rats were impaired in comparisons with 6-month-old rats on measures of place learning, working memory, reference memory, and perseveration in water-maze tasks. Aged rats that were impaired on one measure of memory, however, were not necessarily impaired on other measures. ChAT activity in the ventromedial and dorsolateral neostriatum of aged rats was significantly reduced in comparisons with young rats whereas no difference was found in the hippocampus. Aged rats with the most ChAT activity in the anterior ventromedial neostriatum performed best on the place-learning and reference memory tasks but also made the most perseverative errors on the working memory task. In addition, young and aged rats with the most ChAT activity in the anterior dorsolateral neostriatum were those with the least accurate working memory. No relationships were found between ChAT activity in the hippocampus and spatial memory. Thus age-related memory impairment has components that can be segregated by measuring relationships between cholinergic integrity in subregions of the anterior neostriatum and memory tasks with different strategic requirements.     

Reflections on trauma,symbolization and psychic pain in a case of neurosis and a case of psychosis

This paper seeks to advance some considerations on trauma, historical reality, its symbolization and the psychic pain generated by the investigation of unconscious processes in psychoanalytic treatment. These themes will be explored by demonstrating the differences arising between traumatic experiences and their expression in phantasy, as they occurred in a case of neurosis and another of psychosis. In each case, the differences in the features of the symbolization and the processes of working through shall also be taken into consideration. Particular attention shall be paid to the specific difficulties encountered by the analyst in the interpretative treatment of the trauma resulting from the amount of psychic pain induced in the patient, which at times proves to be an insurmountable barrier and a destructive distortion of the process.
