“…In contrast with humans, mice did not show a tendency to reduce the number of sequential patterns used to explore the set of poles. This finding is consistent with results that we report elsewhere (De Lillo, 2012, 2019De Lillo et al, 2014), which show that in other search tasks the ability to selfregulate and develop fixed search sequences is a peculiar characteristic of primates (and humans in particular) but not observed in mice (Valsecchi et al, 2000).…”

“…In primates, the temporal organisation of behaviour is mediated by frontal functions (Carlen, 2017). Moreover, the strategic use of predictable TP of resource availability in our task could be considered an instance of a more general ability to pick up patterns in other task domains (see De Lillo, 2012Lillo, , 2019. Such type of ability is also associated with frontal functions in humans and with the activity of the dorsolateral prefrontal cortex (DLPFC) in particular (Bor et al, 2003).…”

“…It has been pointed out that self-regulatory processes, occurring when repeatedly practising a search task, can lead to the development of fixed search sequences (De Lillo, 2012, 2019De Lillo et al, 1997, 1998Hills et al, 2015). Using one fixed sequence or a small subset of sequences, among all the paths that can be taken to explore a set, can have the effect of off-loading WM.…”

“…This is critical for the characterisation of what is unique about human cognition and for the understanding of its architecture and evolutionary history (Carlen, 2017;Carruthers, 2013;Passingham, 2008). It has been argued that comparisons between humans and non-human primates, because of their close taxonomic distance and allegedly similar brain organisation, allow the best possible inferences about human cognitive idiosyncrasies and their evolution (Antinucci, 1989;De Lillo, 2012, 2019Uylings et al, 2003). Nonetheless, key psychological processes and competences can be observed in both humans and animals, which are taxonomically very distant from our species such as rodents and birds (e.g., Davis, 1992;Von Fersen et al, 1991) and can be explained by basic associative mechanisms that pertain to most animals (Frank et al, 2005).…”

Assessing variations in cognitive function between humans and animals is vital for understanding the idiosyncrasies of human cognition and for refining animal models of human brain function and disease. We determined memory functions deployed by mice and humans to support foraging with a search task acting as a test battery. Mice searched for food from the top of poles within an open-arena. Poles were divided into groups based on visual cues and baited according to different schedules. White and black poles were baited in alternate trials. Striped poles were never baited. The requirement of the task was to find all baits in each trial. Mice’s foraging efficiency, defined as the number of poles visited before all baits were retrieved, improved with practice. Mice learnt to avoid visiting un-baited poles across trials (Long-term memory) and revisits to poles within each trial (Working memory). Humans tested with a virtual-reality version of the task outperformed mice in foraging efficiency, working memory and exploitation of the temporal pattern of rewards across trials. Moreover, humans, but not mice, reduced the number of possible movement sequences used to search the set of poles. For these measures interspecies differences were maintained throughout three weeks of testing. By contrast, long-term-memory for never-rewarded poles was similar in mice and humans after the first week of testing. These results indicate that human cognitive functions relying upon archaic brain structures may be adequately modelled in mice. Conversely, modelling in mice fluid skills likely to have developed specifically in primates, requires caution.

“…Taken together, the results of these studies point to a trend in the ability to benefit from clustered search spaces that parallels the taxonomic distance of the species tested from humans (and would also parallel the relative expansion of the frontal cortex of the species involved: Fuster, 2008;Passingham & Smaers, 2014). In fact, neither of the two rodent species-mice (Valsecchi et al, 2000) and rats (De Lillo, 2012, 2019Foti et al, 2007)-displayed more efficient searches in clustered sets compared with diffuse matrices of locations. Moreover, neither mice nor rats performed systematic searches that explored each set exhaustively before moving onto the next.…”

Search – the problem of exploring a space of alternatives in order to identify target goals – is a fundamental behaviour for many species. Although its foundation lies in foraging, most studies of human search behaviour have been directed towards understanding the attentional mechanisms that underlie the efficient visual exploration of two-dimensional scenes. With this review, we aim to characterise how search behaviour can be explained across a wide range of contexts, environments, spatial scales, and populations, both typical and atypical. We first consider the generality of search processes across psychological domains. We then review studies of interspecies differences in search. Finally, we explore in detail the individual and contextual variables that affect visual search and related behaviours in established experimental psychology paradigms. Despite the heterogeneity of the findings discussed, we identify that variations in control processes, along with the ability to regulate behaviour as a function of the structure of search space and the sampling processes adopted, to be central to explanations of variations in search behaviour. We propose a tentative theoretical model aimed at integrating these notions and close by exploring questions that remain unaddressed.

La prueba de Bloques de Corsi es utilizada en Psicología y ciencias cognitivas para evaluar la memoria de trabajo visoespacial. La versión original era administrada por un/a investigador/a manualmente, lo cual podía facilitar la comisión de errores de evaluación, así como generar dificultades para reproducir la experiencia de manera precisa. A partir de ello, se desarrollaron diversas versiones digitales que usaban computadoras o tabletas, lo cual generó debates respecto de las posibles diferencias diagnósticas entre dichas versiones digitales y las mismas pruebas en versiones manuales. En este trabajo, se presenta el desarrollo del CorsiBot, una versión manual y automatizada que permite estudiar el desempeño y las estrategias de resolución de la https://doi.org/10.16888/interd.2023.40.3.17 CorsiBot: evaluación de la memoria de trabajo prueba Bloques de Corsi. El trabajo tuvo como objetivo la comparación del desempeño de participantes adultos en una versión digital de la tarea de Corsi y el CorsiBot, así como comparar la experiencia subjetiva de los/as participantes al utilizar cada versión.El dispositivo se ha probado en una muestra de personas adultas con quienes se pudieron verificar similitudes y diferencias con una versión digital. En particular, los participantes obtuvieron una proporción similar de ensayos correctos en cada versión de Corsi, pero mostraron diferencias en los tipos de errores cometidos.
