ABSTRACT This work presents a new set of 360 high quality colour images belonging to 23 semantic subcategories. Two hundred and thirty-six Spanish speakers named the items and also provided data from seven relevant psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived from Internet search hits. Apart from the high number of variables evaluated, knowing that it affects the processing of stimuli, this new set presents important advantages over other similar image corpi: (a) this corpus presents a broad number of subcategories and images; for example, this will permit researchers to select stimuli of appropriate difficulty as required, (e.g., to deal with problems derived from ceiling effects); (b) the fact of using coloured stimuli provides a more realistic, ecologically-valid, representation of real life objects. In sum, this set of stimuli provides a useful tool for research on visual object- and word-processing, both in neurological patients and in healthy controls.

    ABSTRACT: The Boston Naming Test (BNT) (Kaplan, Goodglass, & Weintraub, 1983 ) is the most commonly used test of confrontation naming in neuropsychology (Rabin, Barr, & Burton, 2005 ). However, there are significant criticisms of the BNT which suggest that it might not be the assessment measure of choice. These criticisms are that the BNT has poor psychometric properties, is not adequately standardized, and has inadequate norms. It is further suggested that when considered in the context of contemporary conceptualizations of the neuropsychology of naming, the BNT does not adequately capture the processes known to be required for successful naming, and does not sample widely enough from the content domain of "naming". These criticisms suggest that the BNT is flawed as a measure of naming, and are discussed in detail in this review. Other stand-alone visual confrontation naming tasks are reviewed to evaluate whether any might be viable substitutes for the BNT in clinical neuropsychology. The Naming Test from the Neuropsychological Assessment Battery (Stern & White, 2009 ) was identified as a possible alternative to the BNT, however, neither of these tests was designed with reference to models of the neuropsychology of naming, and development of a new test of naming is indicated.

    ABSTRACT: Memory stability and change are considered opposite outcomes. We tested the counterintuitive notion that both depend on one process: hippocampal binding of memory features to associatively novel information, or associative novelty binding (ANB). Building on the idea that dominant memory features, or "traces," are most susceptible to modification, we hypothesized that ANB would selectively involve dominant traces. Therefore, memory stability versus change should depend on whether the currently dominant trace is old versus updated; in either case, novel information will be bound with it, causing either maintenance (when old) or change (when updated). People in our experiment studied objects at locations within scenes (contexts). During reactivation in a new context, subjects moved studied objects to new locations either via active location recall or by passively dragging objects to predetermined locations. After active reactivation, the new object location became dominant in memory, whereas after passive reactivation, the old object location maintained dominance. In both cases, hippocampal ANB bound the currently dominant object-location memory with a context with which it was not paired previously (i.e., associatively novel). Stability occurred in the passive condition when ANB united the dominant original location trace with an associatively novel newer context. Change occurred in the active condition when ANB united the dominant updated object location with an associatively novel and older context. Hippocampal ANB of the currently dominant trace with associatively novel contextual information thus provides a single mechanism to support memory stability and change, with shifts in trace dominance during reactivation dictating the outcome.

    ABSTRACT: The role of objects' motor affordances in cognition is a topic that has gained in popularity over the last decades. However, few studies exist that have normed the different motor dimensions of the objects; this limits researchers regarding usable stimuli, as well as comparability between studies. In the present study, we normed a set of 560 objects on four motor dimensions: the ease with which they can be grasped, moved, and pantomimed and the number of actions they afford. We then examined whether these four dimensions predict objects' naming latency. We believe that these norms will allow researchers interested in the role of motor affordances to have a better control over the dimensions they want to manipulate.
