Decision making and visibility in cats (Felis catus) in a progressive elimination task

When making decisions animals can rely on information stored in memory and/or on information available through perceptual processes. Under some circumstances, perceptual access to a relevant piece of information can be lost as when a prey hides under a cover. If this piece of information is critical, the animal must be able to keep it active in the working memory until the final decision is made. Species endowed with object permanence can to a certain extent overcome such a lack of perceptual access. Numerous studies have investigated object permanence in animals, but no study systematically examined the interaction when making a decision between an information directly available through perception and an information that can no longer be perceived. In the present study, domestic cats (Felis catus) were administered a progressive elimination task in which they had to visit and deplete either two visible and one hidden target (e.g., Experiments 1 and 2) or one visible and two hidden targets (e.g., Experiments 3 and 4). The cats were brought back to the starting point after each visit to any target whether that target had been previously visited or not. The results revealed that the cats searched at the visible target(s) first and at the hidden target(s) last, which was referred to as the visibility rule. The results also revealed that the position of the bowl that was distinct (e.g., the visible bowl when the two other ones were hidden and the opposite) influenced the way this cognitive rule was implemented. More specifically, when the intermediate bowl was distinct the visibility rule was readily implemented but when either the right of the left bowl was distinct the visibility was violated. That is the cats did no longer choose the visible target(s) first. The visibility rule was interpreted in terms of optimization principles, the external distinct target effect was interpreted in terms of divided attention and lateralization.     

On‐line ostracism affects children differently from adolescents and adults

This research examines adults', and for the first time, children's and adolescents' reaction to being ostracized and included, using an on‐line game, ‘Cyberball’ with same and opposite sex players. Ostracism strongly threatened four primary needs (esteem, belonging, meaning, and control) and lowered mood among 8‐ to 9‐year‐olds, 13‐ to 14‐year‐olds, and adults. However, it did so in different ways. Ostracism threatened self‐esteem needs more among 8‐ to 9‐year‐olds than older participants. Among 13‐ to 14‐year‐olds, ostracism threatened belonging more than other needs. Belonging was threatened most when ostracism was participants' first experience in the game. Moreover, when participants had been included beforehand, ostracism threatened meaning needs most strongly. Gender of other players had no effect. Practical and developmental implications for social inclusion and on‐line experiences among children and young people are discussed.     

Emotional encounter: Researching young people's intimate spaces in their information & communication technology practices

This article discusses the role and place of emotions in research and, particularly, in researching young people's intimate spaces in their information and communication technology (ICT) practices. It echoes Harris and Hutington's remarks (2001) that we cannot claim to explore and understand people's social life, without taking into account the potentially powerful role played by emotion. In this paper, I show how adopting a relational position in terms of theoretical framework, such as I have developed it, has two main implications: First, it considers the exploration of young people's intimate sphere of emotion as a central task; second, it involves discussing the methodological tools that render such an exploration possible. I present how I translated these implications, by means of an ethnography of young people's practices in Montreal and, notably, by recursive interviews. Finally, I show how emotions cross over, and are imbricated in, both young people's practices and in my relationship with the young people themselves, showing all the great wealth of this emotional encounter.     

Unconscious phantasy and its conceptualizations: An attempt at conceptual integration

That there is a lack of consensus as to how to decide between competing, at times even contradictory theories, and about how to integrate divergent concepts and theories is well known. In view of this situation, the IPA Committee on Conceptual Integration (2009–2013) developed a method for comparing the different versions of any given concept, together with the underlying theories and fundamental assumptions on which they are based. Only when situated in the same frame of reference do similarities and differences begin to appear in a methodically comprehensible and reproducible form. After having studied the concept of enactment followed by the publication of a paper in this Journal in 2013, we proceeded to analyze the concept of unconscious phantasy while at the same time continuing to improve our method. Unconscious phantasy counts among the central concepts in psychoanalysis. We identified a wide range of definitions along with their various theoretical backgrounds. Our primary concern in the present paper addresses the dimensional analysis of the semantic space occupied by the various conceptualizations. By way of deconstructing the concepts we endeavoured to establish the extent to which the integration of the different conceptualizations of unconscious phantasy might be achieved.

Two-to-three-year-old children's interactions with peers in child-care centres: Effects of spatial distance to caregivers

In child-care centres, the influence of caregivers on the development of peer interactions seems ambivalent and mixed results are reported in the literature. Adopting an environmental approach, we examined the effects of the caregivers’ spatial proximity on children's social behaviour. The study was carried out with 175 children (18-40 months) in 12 child-care-centre groups. Children's behaviours were observed during free plays, and both children and caregivers’ locations were recorded. When peers were nearby, children's social behaviours were compared when they were in the immediate proximity (within 2 m) and out of the immediate proximity of a caregiver. Results show that in the latter situation children spend substantially more time addressing social overture to peers and interacting with them; positive interactions with peers show a particularly marked difference. This pattern of results is exhibited by the greater part of the children. Whatever the child-care-centre group, the age subgroup or the gender considered similar results are found. Results also demonstrate that when children are in the immediate proximity of caregivers they are socially oriented towards the attractive adult partners rather than towards peers.     

Attentional engagement is not sufficient to prevent spatial capture

What conditions, if any, can fully prevent attentional capture (i.e., involuntary allocation of spatial attention to an irrelevant object) has been a matter of debate. In a previous study, Folk, Ester, and Troemel (Psychonomic Bulletin & Review 16:127–132, 2009) suggested that attentional capture can be blocked entirely when attention is already engaged in a different object. This conclusion relied on the finding that in a search for a known-color target in a rapid serial visual presentation stream, a peripheral distractor with the target color did not further impair target identification performance when a distractor also with the target color that appeared in the stream had already captured attention. In the present study, we argue that this conclusion is unwarranted, because the effects of the central and peripheral distractors could not be disentangled. In order to isolate the effect of the peripheral distractor, we introduced a distractor–target letter compatibility manipulation. Our results showed that the peripheral distractor summoned attention, irrespective of whether attention had just been engaged. We conclude that neither spatially focused attention nor attentional engagement is sufficient to prevent attentional capture.
