What happened? Do preschool children and capuchin monkeys spontaneously use visual traces to locate a reward?

Proc Biol Sci 2021 08 4;288(1956):20211101. Epub 2021 Aug 4.

School of Psychology and Neuroscience, University of St Andrews, St Andrews, UK.

The ability to infer unseen causes from evidence is argued to emerge early in development and to be uniquely human. We explored whether preschoolers and capuchin monkeys could locate a reward based on the physical traces left following a hidden event. Preschoolers and capuchin monkeys were presented with two cups covered with foil. Read More

Pharmacists among Members of the Czech-Moravian Capuchin Province.

Karel Nesměrák

Ceska Slov Farm 2019 ;68(6):243-262

Based on a profound examination and evaluation of archival materials, the paper reconstructs the lives of eighteen pharmacists - members of the Czech-Moravian Capuchin Province from the 17th to the 19th century, of which sixteen served as monastic pharmacists. In addition to the identified biographical data (based on archival materials), the Latin summary reports on the life of a particular capuchin on the occasion of his death (the so-called elogia) from the Capuchin Provincial Chronicle (Annales capucinorum) are edited, together with their commented Czech translation. The discovered data allow a deeper insight into the pharmaceutical history of the Czech-Moravian Capuchin Province, where three monastic pharmacies were operated in Brno, Prague in Hradčany and Olomouc, and also a monastic pharmaceutical study was established.

Positional behavior and substrate use in wild adult bearded capuchin monkeys (Sapajus libidinosus).

Am J Primatol 2019 12 12;81(12):e23067. Epub 2019 Nov 12.

Department of Psychology, University of Georgia, Athens, Georgia.

Natural selection for positional behavior (posture and locomotion) has at least partially driven the evolution of anatomical form and function in the order Primates. Examination of bipedal behaviors associated with daily activity patterns, foraging, and terrestrial habitat use in nonhuman primates, particularly those that adopt bipedal postures and use bipedal locomotion, allows us to refine hypotheses concerning the evolution of bipedalism in humans. This study describes the positional behavior of wild bearded capuchins (Sapajus libidinosus), a species that is known for its use of terrestrial substrates and its habitual use of stones as tools.

A competitive drive? Same-sex attentional preferences in capuchins.

Am J Primatol 2019 07 12;81(6):e22998. Epub 2019 Jun 12.

Department of Psychology, Franklin and Marshall College, Lancaster, Pennsylvania.

In primates, faces provide information about several characteristics of social significance, including age, physical health, and biological sex. However, despite a growing literature on face processing and visual attention in a number of primate species, preferences for same- or opposite-sex faces have not yet been examined. In the current study, we explore the role of conspecific sex on visual attention in two groups of capuchin monkeys. Read More

Thalamic Inputs to Posterior Parietal Cortical Areas Involved in Skilled Forelimb Movement and Tool Use in the Capuchin Monkey.

Cereb Cortex 2019 12;29(12):5098-5115

Institute of Biophysics Carlos Chagas Filho, Federal University of Rio de Janeiro, 21941-902, Rio de Janeiro, Brazil.

The posterior parietal cortex (PPC) is a central hub for the primate forebrain networks that control skilled manual behavior, including tool use. Here, we quantified and compared the sources of thalamic input to electrophysiologically-identified hand/forearm-related regions of several PPC areas, namely areas 5v, AIP, PFG, and PF, of the capuchin monkey (Sapajus sp). We found that these areas receive most of their thalamic connections from the Anterior Pulvinar (PuA), Lateral Posterior (LP) and Medial Pulvinar (PuM) nuclei. Read More

Monkeys (Sapajus apella and Macaca tonkeana) and great apes (Gorilla gorilla, Pongo abelii, Pan paniscus, and Pan troglodytes) play for the highest bid.

J Comp Psychol 2019 08 27;133(3):301-312. Epub 2018 Dec 27.

Institut Pluridisciplinaire Hubert Curien, University of Strasbourg.

Many studies investigate the decisions made by animals by focusing on their attitudes toward risk, that is, risk-seeking, risk neutrality, or risk aversion. However, little attention has been paid to the extent to which individuals understand the different odds of outcomes. In a previous gambling task involving 18 different lotteries (Pelé, Broihanne, Thierry, Call, & Dufour, 2014), nonhuman primates used probabilities of gains and losses to make their decision.

Friar Leopold Mandic (1866-1942): the computed tomography of the body of a saint.

Surg Radiol Anat 2018 Aug 13;40(8):967-975. Epub 2018 Jun 13.

Department of Neuroscience, Institute of Human Anatomy, University of Padova, Via A. Gabelli 65, 35127, Padova, Italy.

Purpose: In forensic clinical anatomy computed tomography (CT) is used in post-mortem radiological investigation as an objective nondestructive documentation of the body surface and of the interior of the body. This technique is applied also in paleopathology, in particular in mummy studies, with the aim of providing a permanent record of the mummy's features, investigating the embalming procedure employed and analyzing the extent of the preservation in detail.

Methods: For the Extraordinary Jubilee of Mercy, the mortal remains of Saint Leopold Mandic and Saint Pio da Pietralcina, as examples of Mercy known by everyone, have been brought to Rome in February 2016. Read More

Through their eyes: The influence of social models on attention and memory in capuchin monkeys (Sapajus apella).

J Comp Psychol 2018 05 8;132(2):210-219. Epub 2018 Mar 8.

Department of Psychology, Franklin & Marshall College.

The ability to learn socially is of critical importance across a wide variety of species, as it allows knowledge to be passed quickly among individuals without the need of time-consuming trial-and-error learning. Among primates, social learning research has been particularly focused on foraging tasks, including transmission dynamics and the demonstration characteristics that appear to support social learning. Less work has focused on the attentional salience of the information being viewed, especially in New World monkeys. Read More

Irrational choice behavior in human and nonhuman primates.

Anim Cogn 2018 03 2;21(2):227-234. Epub 2018 Jan 2.

Agnes Scott College, 141 E. College Ave., Decatur, GA, 30030, USA.

Choice behavior in humans has motivated a large body of research with a focus on whether decisions can be considered to be rational. In general, humans prefer having choice, as do a number of other species that have been tested, even though having increased choice does not necessarily yield a positive outcome. Humans have been found to choose an option more often only because the opportunity to select it was diminishing, an example of a deviation from economic rationality. Read More

Connectivity of the Pulvinar.

Adv Anat Embryol Cell Biol 2018 ;225:19-29

Laboratory of Cognitive Physiology, Institute of Biophysics Carlos Chagas Filho, Federal University of Rio de Janeiro, Rio de Janeiro, Brazil.

Pulvinar connectivity has been studied using a variety of neuroanatomical tracing techniques in both New and Old World monkeys. Connectivity studies have revealed additional maps of the visual field other than those described using electrophysiological techniques, such as P3 in the capuchin monkey and P3/P4 in the macaque monkey. In this chapter, we argue that with increasing cortical size, the pulvinar developed new functional subdivisions in order to effectively interconnect and interact with the cortex. Read More

Seasonality, richness and prevalence of intestinal parasites of three neotropical primates ( and ) in a fragmented forest in Colombia.

Int J Parasitol Parasites Wildl 2017 Dec 21;6(3):202-208. Epub 2017 Jul 21.

Centro de Investigaciones en Microbiología y Parasitología Tropical, CIMPAT, Departamento de Ciencias Biológicas, Universidad de los Andes, Cra. 1 N° 18-12, Bogotá, Colombia.

Studies on parasites infecting non-human primates are essential to better understand the potential threat to humans of zoonoses transmission, particularly under the current processes of pervasive land use change and biodiversity loss. The natural ecosystems in the Middle Magdalena river basin in Colombia have suffered a dramatic reduction and transformation into pastures and agroindustrial monocultures, threatening their biodiversity, and probably affecting the dynamics between parasites and their hosts, as well as altering the disease transmission cycles between wild populations and humans. This study evaluated seasonality, prevalence and richness of intestinal parasites in three species of neotropical primates: and in a fragmented forest in the Middle Magdalena river valley, Colombia.

Social and demographic correlates of male androgen levels in wild white-faced capuchin monkeys (Cebus capucinus).

Am J Primatol 2017 07 7;79(7). Epub 2017 Apr 7.

Max Planck Institute for Evolutionary Anthropology, Deutscher Platz 6, Leipzig, Germany.

The Challenge Hypothesis, designed originally to explain the patterning of competitive behavior and androgen levels in seasonally breeding birds, predicts that males will increase their androgen levels in order to become more competitive in reproductive contexts. Here we test predictions derived from the Challenge Hypothesis in white-faced capuchin monkeys (Cebus capucinus), a species that has somewhat seasonal reproduction. We analyzed demographic and hormonal data collected over a 5. Read More

Chapparvoviruses occur in at least three vertebrate classes and have a broad biogeographic distribution.

J Gen Virol 2017 02;98(2):225-229

MRC-University of Glasgow Centre for Virus Research, Glasgow, UK.

Chapparvoviruses are a highly divergent group of parvoviruses (family Parvoviridae) that have recently been identified via metagenomic sampling of animal faeces. Here, we report the sequences of six novel chapparvoviruses identified through both metagenomic sampling of bat tissues and in silico screening of published vertebrate genome assemblies. The novel chapparvoviruses share several distinctive genomic features and group together as a robustly supported monophyletic clade in phylogenetic trees. Read More

Motor, cognitive, and affective areas of the cerebral cortex influence the adrenal medulla.

Proc Natl Acad Sci U S A 2016 08 15;113(35):9922-7. Epub 2016 Aug 15.

University of Pittsburgh Brain Institute, University of Pittsburgh School of Medicine, Pittsburgh, PA 15261; Systems Neuroscience Institute, University of Pittsburgh School of Medicine, Pittsburgh, PA 15261; Center for the Neural Basis of Cognition, University of Pittsburgh School of Medicine, Pittsburgh, PA 15261; Department of Neurobiology, University of Pittsburgh School of Medicine, Pittsburgh, PA 15261;

Modern medicine has generally viewed the concept of "psychosomatic" disease with suspicion. This view arose partly because no neural networks were known for the mind, conceptually associated with the cerebral cortex, to influence autonomic and endocrine systems that control internal organs. Here, we used transneuronal transport of rabies virus to identify the areas of the primate cerebral cortex that communicate through multisynaptic connections with a major sympathetic effector, the adrenal medulla.

Individual participation in intergroup contests is mediated by numerical assessment strategies in black howler and tufted capuchin monkeys.

Philos Trans R Soc Lond B Biol Sci 2015 Dec;370(1683):20150007

Department of Anthropology, University of Texas at Austin, 2201 Speedway C3200, Austin, TX 78712, USA Department of Anthropology, Stony Brook University, Social and Behavioral Sciences Building S-501, Stony Brook, NY 11794-4364, USA.

Asymmetries in resource-holding potential between opposing groups frequently determine outcomes of intergroup contests. Since both numerical superiority and high intergroup dominance rank may confer competitive advantages, group members should benefit from assessing the relative strength of rivals prior to engaging in defensive displays. However, differences in individual assessment may emerge when cost-benefit trade-offs differ among group members. Read More
