Social cognition is not reducible to theory of mind: When children use deontic rules to predict the behaviour of others

The objective of this paper is to discuss whether children have a capacity for deontic reasoning that is irreducible to mentalizing. The results of two experiments point to the existence of such non‐mentalistic understanding and prediction of the behaviour of others. In Study 1, young children (3‐ and 4‐year‐olds) were told different versions of classic false‐belief tasks, some of which were modified by the introduction of a rule or a regularity. When the task (a standard change of location task) included a rule, the performance of 3‐year‐olds, who fail traditional false‐belief tasks, significantly improved. In Study 2, 3‐year‐olds proved to be able to infer a rule from a social situation and to use it in order to predict the behaviour of a character involved in a modified version of the false‐belief task. These studies suggest that rules play a central role in the social cognition of young children and that deontic reasoning might not necessarily involve mind reading.

Histamine reverses a memory deficit induced in rats by early postnatal maternal deprivation

Early partial maternal deprivation causes long-lasting neurochemical, behavioral and brain structural effects. In rats, it causes a deficit in memory consolidation visible in adult life. Some of these deficits can be reversed by donepezil and galantamine, which suggests that they may result from an impairment of brain cholinergic transmission. One such deficit, representative of all others, is an impairment of memory consolidation, clearly observable in a one-trial inhibitory avoidance task. Recent data suggest a role of brain histaminergic systems in the regulation of behavior, particularly inhibitory avoidance learning. Here we investigate whether histamine itself, its analog SKF-91844, or various receptor-selective histamine agonists and antagonists given into the CA1 region of the hippocampus immediately post-training can affect retention of one-trial inhibitory avoidance in rats submitted to early postnatal maternal deprivation. We found that histamine, SKF-91844 and the H2 receptor agonist, dimaprit enhance consolidation on their own and reverse the consolidation deficit induced by maternal deprivation. The enhancing effect of histamine was blocked by the H2 receptor antagonist, ranitidine, but not by the H1 receptor antagonist pyrilamine or by the H3 antagonist thioperamide given into CA1 at doses known to have other behavioral actions, without altering locomotor and exploratory activity or the anxiety state of the animals. The present results suggest that the memory deficit induced by early postnatal maternal deprivation in rats may in part be due to an impairment of histamine mediated mechanisms in the CA1 region of the rat hippocampus.     

Cross-sectional transmission electron microscopy of electrodeposited Ni-P alloys

Abstract

Ultramicrotoming has been employed to prepare thin cross-sections of Ni-P alloys electrodeposited on to a copper substrate. The sections, as thin as 10nm or even less, can be prepared readily with negligible damage to the alloys. Subsequent examination of the ultramicrotomed sections in an analytical transmission electron microscope has revealed that Ni-P alloys of low P content consist of fine layers of different composition and crystallinity. High-resolution transmission electron microscopy of ultramicrotomed sections has also revealed the presence of ordered regions, a few nanometres in size, in the Ni₇₇P₂₃ alloy which has been thought previously to be amorphous.     

Effect of acoustic cue modifications on evoked vocal response to calls in zebra finches (Taeniopygia guttata)

Besides their song, which is usually a functionally well-defined communication signal with an elaborate acoustic structure, songbirds also produce a variety of shorter vocalizations named calls. While a considerable amount of work has focused on information coding in songs, little is known about how calls' acoustic structure supports communication processes. Because male and female zebra finches use calls during most of their interactions and answer to conspecific calls without visual contact, we aimed at identifying which calls' acoustic cues are necessary to elicit a vocal response. Using synthetic zebra finch calls, we examined evoked vocal response of male and female zebra finches to modified versions of the distance calls. Our results show that the vocal response of zebra finches to female calls requires the full harmonic structure of the call, whereas the frequency downsweep of male calls is necessary to evoke a vocal response. It is likely that both female and male calls require matching a similar frequency bandwidth to trigger a response in conspecific individuals.     

Comparison of pausing behavior in children who stutter and children who have Asperger syndrome

Purpose

The objective of this research was to compare the number and types of grammatical and non-grammatical silent pauses presented by stutterers and subjects with Asperger syndrome in their narratives.

Method

Ten children who stutter and four participants with Asperger syndrome (mean ages of both groups 10 years) were assessed at the Speech and Language Disorders Department of the Universidade Federal de São Paulo/Brasil. They narrated a story based on a pre-selected sequence of pictures. They were filmed and their productions were analyzed using version 5.0.47 of Praat (http://www.fon.hum.uva.nl/praat/download_win.html). Silent intervals in the speech that ranged from 0.25 to 4 s were considered pauses. The pauses were classified as grammatical and non-grammatical, depending on the words that preceded and followed them.

Results

Both groups presented grammatical and non-grammatical pauses and the former predominated. The children with Asperger syndrome produced a greater number of pauses than the stutterers.Educational objectives: The reader will be able to: (1) characterize the use of pauses in the oral narrative; (2) distinguish a grammatical pause from a non-grammatical pause regarding the use and function; (3) recognize the pattern of pause found in the two populations.     

The cost of being watched: Stroop interference increases under concomitant eye contact

Current models in social neuroscience advance that eye contact may automatically recruit cognitive resources. Here, we directly tested this hypothesis by evaluating the distracting strength of eye contact on concurrent visual processing in the well-known Stroop’s paradigm. As expected, participants showed stronger Stroop interference under concomitant eye contact as compared to closed eyes. Two control experiments allowed ruling out low-level account of this effect as well as non-specific effect of the presence of open eyes. This suggests that refraining from processing eye contact is actually as difficult as refraining from word reading in the Stroop task. Crucially, the eye contact effect was obtained while gaze was not under the direct focus of attention and the participants were faced with another powerful distracter (the incongruent word) in the task at hand. Thus, there is a cost of being watched even in circumstances where the processing of direct gaze is strongly disfavored. The present results emphasize the crucial status of eye contact in human cognition.     

Borders, Globalization and Eucharistic Hospitality

Abstract :  This article relates the sacrament of the Eucharist to world migration and hospitality. To weave these themes is to find borders all around the Eucharistic table/altar, borders often unnoticed but borders that define economic, social, cultural, sexual and class divides. Using the notion of  borderless borders  and engaging Jacques Derrida's notion of hospitality, the author tries to expand the possibilities of the Christian demand to welcome people in and around and through the eucharistic sacrament as people gather with one another to be with one another and issue this constant call of welcome to whomever wants to come and eat.     

Living in the Borderlands—An Identity and a Proposal

Abstract :  We live in the borderlands, a place not of separation but of coming together, of connection. The continuing efforts to discern what it means to express who we are as religious people, and what it means regarding the religious identity of those who live in the borderlands is the focus of this study. In many ways, this identity is one that is in the process of being restored, renewed, and reaffirmed after many years of a combination of benign neglect and overt suppression.
