    What working memory is for

    Glenberg focuses on conceptualizations that change from moment to moment, yet he dismisses the concept of working memory (sect. 4.3), which offers an account of temporary storage and on-line cognition. This commentary questions whether Glenberg's account adequately caters for observations of consistent data patterns in temporary storage of verbal and visuospatial information in healthy adults and in brain-damaged patients with deficits in temporary retention.</jats:p

    An internet study of prospective memory across adulthood

    Get PDF
    In an Internet study, 73,018 18-79-year-olds were asked to “remember to click the smiley face when it appears”. A smiley face was present/absent at encoding, and participants were told to expect it “at the end of the test”/“later in the test.” In all 4 conditions, it occurred after 20 min of retrospective memory tests. Prospective remembering benefited at all ages from both prior target exposure and temporal uncertainty; moreover, it resembled working memory in its linear decline from young adulthood. The study demonstrates the power of Internet methodology to reveal age-related deficits in a single-trial prospective memory task outside the laboratory

    2666, o la legitimidad de la literatura en tiempos 'post'

    Get PDF
    En este artículo, se analiza la novela 2666 de Roberto Bolaño como emblemática de la tradición narrativa posapocalíptica, donde se pone de manifiesto el agotamiento del poder, el final de una época que no conoce zonas no contaminadas por la violencia. De allí que la representación más adecuada del mundo contemporáneo aparezca como una pesadilla caracterizada por esa violencia y por la guerra permanente, verdaderas sinécdoques de la historia contemporánea. 2666 clausura el siglo XX expresando dos naufragios: el primero atañe a la militancia de la izquierda, en la que todavía creía la generación del propio Bolaño, representada por un personaje, Amalfitano, que encarna las derrotas y pérdidas del proyecto revolucionario. El segundo naufragio es el que ha afectado a una concepción humanista del arte; en la actualidad, se asume que la literatura ya raramente incomoda o ilumina. Atrás ha quedado la sacralización de la figura del artista que marcó el período modernista de nuestra cultura, por lo que el arte ha perdido su poder emancipador, ha dejado de ser una fuerza civilizadora para ponerse al servicio de regímenes totalitarios, o para disolverse en el triunfo banal de la industria cultural. El texto parece proponer que para recuperar cierta legitimidad, en una obra debe coincidir el compromiso estético con el ético, por lo que los procesos de ficcionalización no pueden entenderse como meros proyectos estéticos

    Una muchacha muy bella de Julián López, o el gesto reparador de la escritura

    ABSTRACT This article focusses on the aspects that make Julián López’s novel Una muchacha muy bella (2013) original. First, we will examine how this text compares to other stories written by the post-dictatorial Argentine “second generation”. Then we will look into the strategies used by the narrator to cope with the trauma of his mother’s disappearance, where ellipsis, which in turn leads to compensating techniques, seems particularly noticeable. Finally, we will focus on a number of interventions of the text – such as the poeticization of experience and the importance attached to reading – that make it go against the flow and destabilize certain predominant practices in the contemporary literary field. KEY WORDS: the literature of the second generation, contemporary argentine narrative prose, Julián Lópe

    Event-based prospective remembering in a virtual world

    Most laboratory-based prospective memory (PM) paradigms pose problems that are very different from those encountered in the real world. Several PM studies have reported conflicting results when comparing laboratory with naturalistic based studies (e.g., Bailey,Henry, Rendell, Phillips & Kliegel, 2010). One key contrast is that for the former, how and when the PM cue is encountered typically is determined by the experimenter, whereas in the latter case, cue availability is determined by participant actions. However, participant-driven access to the cue has not been examined in laboratory studies focused on healthy young adults, and its relationship with planned intentions is poorly understood. Here we report a study of PM performance in a controlled, laboratory setting, but with participant-driven actions leading to the availability of the PM cue. This uses a novel PM methodology based upon analysis of participant movements as they attempted a series of errands in a large virtual building on the computer screen. A PM failure was identified as a situation in which a participant entered and exited the “cue” area outside an errand related room without performing the required errand whilst still successfully remembering that errand post-test. Additional individual difference measures assessed retrospective and working memory capacity, planning ability and PM. Multiple regression analysis showed that the independent measures of verbal working memory span, planning ability and PM were significant predictors of PM failure. Correlational analyses with measures of planning suggest that sticking with an original plan (good or bad) is related to better overall PM performance

    Dual task impairments in vascular dementia

    Several studies have shown that people with Alzheimer's disease (AD) demonstrate difficulties in doing two things at once or 'dual-tasking' and that this dual task impairment is insensitive to normal ageing, chronic depression or prodromal conditions like Mild Cognitive Impairment. It is not known, however, if this impairment is specific to AD, or also present in other dementias, such as vascular dementia (VaD). In this study 15 people with VaD, 25 healthy age-matched and 25 healthy young controls were assessed using a paper and pencil dual tasking paradigm and several measures of working and episodic memory. Age had no effect on dual task performance, but the VaD patients demonstrated a significant impairment in dual tasking ability. Performance on the memory measures was instead affected by age with a further deterioration in the VaD patients. Both dual tasking and memory ability were significantly correlated with disease severity, as assessed by the MMSE. These results indicate that performance on the dual task could be a specific indicator of pathological ageing

    Items on the Left Are Better Remembered

    We report evidence of a new phenomenon from three experiments: a leftward bias when people try to remember visually presented information. Experiments 1 and 2 showed lateral leftward biases in memory in a large (total N&#x3e;60000) sample of participants, with data collected via the British Broadcasting Corporation (BBC) web site. Experiment 3 replicated the findings of a leftwards bias in short-term memory with a more intensive data collection

    Case studies of thermally driven heat pump assisted drying

    In general, most heat losses in industrial dryers arise due to the discharge of humid air. By using heat pump drying (HPD) systems, heat from the exhaust humid air can be recovered, thus improving the energy efficiency substantially. In this study, the performance of thermally driven HP integration in an animal food and a blood dryer were examined. Computer simulation models of the original high temperature dryers and the proposed system with HP integration and auxiliary heating were developed. It is found that, when using a gas engine, the maximum energy cost saving is limited by the temperature of the coolant fluid. The maximum energy cost saving when using a gas turbine is a bit higher, however at a much higher operating temperature
