  • Searching for object pointers in the visual cortex. [Journal Article]
    J Neurophysiol. 2020 May 01; 123(5):1979-1994.Zhu SD, Zhang LA, von der Heydt R
  • We perceive objects as permanent and stable despite frequent occlusions and eye movements, but their representation in the visual cortex is neither permanent nor stable. Feature selective cells respond only as long as objects are visible, and their responses depend on eye position. We explored the hypothesis that the system maintains object pointers that provide permanence and stability. Pointers…
  • Enhancing "self-control": The paradoxical effect of delay of reinforcement. [Journal Article]
    Learn Behav. 2020 Mar; 48(1):165-172.Zentall TR
  • Delay of reinforcement is generally thought to be inversely correlated with speed of acquisition. However, in the case of simultaneous discrimination learning, in which choice results in immediate reinforcement, delay of reinforcement can improve acquisition. For example, in the ephemeral reward task, animals are given a choice between two alternatives, A and B. Choice of A provides reinforcement…
  • Investigating the social environment of the A-not-B search task. [Journal Article]
    Dev Sci. 2019 Nov 08 [Online ahead of print]Dunn K, Bremner JG
  • Controversy exists concerning the origins of object permanence, with different measures suggesting different conclusions. Looking measures have been interpreted as evidence for early understanding (Baillargeon, 1987, Developmental Psychology, 23:655), while Piaget (The construction of reality in the child, 1954) interpreted perseverative reaching behaviour on his AB search task to be indicative o…
  • Neuroimaging Findings on Amodal Completion: A Review. [Journal Article]
    Iperception. 2019 Mar-Apr; 10(2):2041669519840047.Thielen J, Bosch SE, … van Lier R
  • Amodal completion is the phenomenon of perceiving completed objects even though physically they are partially occluded. In this review, we provide an extensive overview of the results obtained from a variety of neuroimaging studies on the neural correlates of amodal completion. We discuss whether low-level and high-level cortical areas are implicated in amodal completion; provide an overview of h…
  • Farm Animal Cognition-Linking Behavior, Welfare and Ethics. [Review]
    Front Vet Sci. 2019; 6:24.Nawroth C, Langbein J, … von Borell E
  • Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioral but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and interact with their environment is of major import…
  • Using automated controlled rearing to explore the origins of object permanence. [Journal Article]
    Dev Sci. 2019 05; 22(3):e12796.Prasad A, Wood SMW, Wood JN
  • What are the origins of object permanence? Despite widespread interest in this question, methodological barriers have prevented detailed analysis of how experience shapes the development of object permanence in newborn organisms. Here, we introduce an automated controlled-rearing method for studying the emergence of object permanence in strictly controlled virtual environments. We used newborn ch…
  • A Detour Task in Four Species of Fishes. [Journal Article]
    Front Psychol. 2018; 9:2341.Sovrano VA, Baratti G, Potrich D
  • Four species of fish (Danio rerio, Xenotoca eiseni, Carassius auratus, and Pterophyllum scalare) were tested in a detour task requiring them to temporarily abandon the view of the goal-object (a group of conspecifics) to circumvent an obstacle. Fishes were placed in the middle of a corridor, at the end of which there was an opaque wall with a small window through which the goal was visible. Midli…
  • Object permanence in Giraffa camelopardalis: First steps in giraffes' physical cognition. [Journal Article]
    J Comp Psychol. 2019 05; 133(2):207-214.Caicoya ÁL, Amici F, … Colell M
  • Although behavior, biology, and ecology of giraffes have been widely studied, little is known about their cognition. Giraffes' feeding ecology and their fission-fusion social dynamics are comparable with those of chimpanzees (Pan troglodytes), suggesting that they might have complex cognitive abilities. To assess this, we tested 6 captive giraffes on their object permanence, short-term memory, an…
  • Intravesical migration of female urethral dilator: a case report of a new urologic emergency in the era of e-commerce. [Case Reports]
    BMC Urol. 2018 Oct 03; 18(1):85.Mogorovich A, Selli C, … De Maria M
  • CONCLUSIONS: The retrieval of foreign objects introduced through body orifices with purpose of sexual gratification is a known urological expertise. Curiously, in the case reported, the patient was able to manipulate the object thus facilitating its correct orientation and passage outside the bladder during micturition. To the best of our knowledge this is the first case of documented spontaneous emission through the urethra of a sizable intravesical foreign body. Sexual gratification in females though the insertion of urethral dilators is a growing practice, as demonstrated by the broad proposal of such instruments on the web. Therefore, the occurrence of accidental intravesical displacement of such kind of foreign body is increasingly likely, and the Urologists must be aware of this possibility.
  • [Feature Integration in Visual Working Memory]. [Review]
    Brain Nerve. 2018 Jul; 70(7):733-743.Saiki J
  • This article reviews studies on feature integration in visual working memory, which is critical for various cognitive activities using visual information. Studies involving change detection and multiple object tracking tasks reported that feature-integrated object representations are successfully maintained, and that the parietal cortex plays a major role. Subsequent studies that involved explici…
  • Where's the cookie? The ability of monkeys to track object transpositions. [Journal Article]
    Anim Cogn. 2018 Jul; 21(4):603-611.Majecka K, Pietraszewski D
  • Object permanence is the ability to represent mentally an object and follow its position even when it has disappeared from view. According to Piaget's 6-stage scale of the sensorimotor period of development, it seems that object permanence appears in Stage 4 and fully develops in Stage 6. In this study, we investigated the ability of some species of monkeys (i.e. pig-tailed macaque, lion-tailed m…
  • Power in methods: language to infants in structured and naturalistic contexts. [Journal Article]
    Dev Sci. 2017 Nov; 20(6)Tamis-LeMonda CS, Kuchirko Y, … Bornstein MH
  • Methods can powerfully affect conclusions about infant experiences and learning. Data from naturalistic observations may paint a very different picture of learning and development from those based on structured tasks, as illustrated in studies of infant walking, object permanence, intention understanding, and so forth. Using language as a model system, we compared the speech of 40 mothers to thei…
  • Intuitive probabilistic inference in capuchin monkeys. [Journal Article]
    Anim Cogn. 2017 Mar; 20(2):243-256.Tecwyn EC, Denison S, … Buchsbaum D
  • The ability to reason about probabilities has ecological relevance for many species. Recent research has shown that both preverbal infants and non-human great apes can make predictions about single-item samples randomly drawn from populations by reasoning about proportions. To further explore the evolutionary origins of this ability, we conducted the first investigation of probabilistic inference…
  • Attentional Predictors of 5-month-olds' Performance on a Looking A-not-B Task. [Journal Article]
    Infant Child Dev. 2016 Jul-Aug; 25(4):233-246.Marcovitch S, Clearfield MW, … Bell MA
  • In the first year of life, the ability to search for hidden objects is an indicator of object permanence and, when multiple locations are involved, executive function (i.e. inhibition, cognitive flexibility and working memory). The current study was designed to examine attentional predictors of search in 5-month-old infants (as measured by the looking A-not-B task), and whether levels of maternal…
  • Scale of emotional development-Short. [Journal Article]
    Res Dev Disabil. 2016 Dec; 59:166-175.Sappok T, Barrett BF, … Morisse F
  • CONCLUSIONS: The SED-S offers an empirical-based, practical tool to assessing ED in adults with ID. Further research will be needed to meet the requirements of a standardized diagnostic instrument.
