    Failures of source memory, which is the ability to recall the specific context in which events took place, have been associated with cognitive decline in the elderly. Source memory deficits appear to be more indicative of age-related memory impairment than disruption of item memory

    Diving into the vertical dimension of elasmobranch movement ecology

    Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and share similar risk to anthropogenic threats that vary on a vertical gradient. We highlight the critical next steps toward incorporating vertical movement into global management and monitoring strategies for elasmobranchs, emphasizing the need to address geographic and taxonomic biases in deployments and to concurrently consider both horizontal and vertical movements

    Repetition Priming of Face Gender Judgments: An Instance Based Explanation.

    Get PDF
    Earlier studies of repetition priming using faces have been interpreted as indicating that such effects are confined to the processing of known faces. The experiment reported here employed 8 rather than the more usual 2 presentation trials and required subjects to make gender decisions ( is it a male or is it a female face?) to both familiar and unfamiliar faces. This allowed the currently favoured recognition unit theories of face processing to be compared with the Logan (1988) instance model. Equivalent repetition priming effects were observed for both familiar and unfamiliar faces and were well fitted by power functions. It is argued that the findings are consistent with the strong predictions made by Logan’s model and pose problems for recognition unit based theories
