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.     

Effects of workaholism on volunteer firefighters’ performance: a moderated mediation model including supervisor recognition and emotional exhaustion

ABSTRACT

Background and Objectives: Although workaholism has been associated with job performance, the mechanisms that explain this relationship remain unclear. In this study, we investigated the conditional indirect effects of workaholism on performance via emotional exhaustion, across low and high levels of supervisor recognition.

Methods: We conducted an empirical cross-sectional study using a sample of 1028 volunteer firefighters who completed a self-report questionnaire assessing workaholism, emotional exhaustion, work performance, and supervisor recognition.

Results: Tests of latent interactions were performed using the latent moderated structural equation modeling approach. Consistent with our predictions, results revealed that the negative indirect effects of workaholism on performance, through emotional exhaustion, were stronger when supervisor recognition was low.

Conclusions: Theorical contributions and perspectives, as well as implications for practice are discussed.     

(Non)words, (non)words, (non)words: evidence for a protolexicon during the first year of life

Previous research with artificial language learning paradigms has shown that infants are sensitive to statistical cues to word boundaries (Saffran, Aslin & Newport, 1996) and that they can use these cues to extract word‐like units (Saffran, 2001). However, it is unknown whether infants use statistical information to construct a receptive lexicon when acquiring their native language. In order to investigate this issue, we rely on the fact that besides real words a statistical algorithm extracts sound sequences that are highly frequent in infant‐directed speech but constitute nonwords. In three experiments, we use a preferential listening paradigm to test French‐learning 11‐month‐old infants' recognition of highly frequent disyllabic sequences from their native language. In Experiments 1 and 2, we use nonword stimuli and find that infants listen longer to high‐frequency than to low‐frequency sequences. In Experiment 3, we compare high‐frequency nonwords to real words in the same frequency range, and find that infants show no preference. Thus, at 11 months, French‐learning infants recognize highly frequent sound sequences from their native language and fail to differentiate between words and nonwords among these sequences. These results are evidence that they have used statistical information to extract word candidates from their input and stored them in a ‘protolexicon’, containing both words and nonwords.     

Towards a better use of psychoanalytic concepts: A model illustrated using the concept of enactment

It is well known that there is a lack of consensus about how to decide between competing and sometimes mutually contradictory theories, and how to integrate divergent concepts and theories. In view of this situation the IPA Project Committee on Conceptual Integration developed a method that allows comparison between different versions of concepts, their underlying theories and basic assumptions. Only when placed in a frame of reference can similarities and differences be seen in a methodically comprehensible and reproducible way. We used “enactment” to study the problems of comparing concepts systematically. Almost all psychoanalytic schools have developed a conceptualization of it. We made a sort of provisional canon of relevant papers we have chosen from the different schools. The five steps of our method for analyzing the concept of enactment will be presented. The first step is the history of the concept; the second the phenomenology; the third a methodological analysis of the construction of the concept. In order to compare different conceptualizations we must know the main dimensions of the meaning space of the concept, this is the fourth step. Finally, in step five we discuss if and to what extent an integration of the different versions of enactment is possible.     

Effects of task relevance and stimulus-driven salience in feature-search mode

Attentional allocation in feature-search mode (W. F. Bacon & H. E. Egeth, 1994) is thought to be solely determined by top-down factors, with no role for stimulus-driven salience. The authors reassessed this conclusion using variants of the spatial cuing and rapid serial visual presentation paradigms developed by C. L. Folk and colleagues (C. L. Folk, R. W. Remington, & J. C. Johnston, 1992; C. L. Folk, A. B. Leber, & H. E. Egeth, 2002). They found that (a) a nonsingleton distractor that possesses the target feature produces attentional capture, (b) such capture is modulated by bottom-up salience, and (c) resistance to capture by irrelevant singletons is mediated by inhibitory processes. These results extend the role of top-down factors in search for a nonsingleton target while arguing against the notion that effects of bottom-up salience and top-down factors on attentional priority are strictly encapsulated within distinct search modes.     

A matter of time: actual time and the production of the past

In psychoanalytic theory, space metaphors are frequently used to describe the psychic apparatus. As for time, it is traditionally invoked under the heading of timelessness of the unconscious, more aptly described as the resistance of the repressed to wearing away with time. This paper examines how the insertion of time into psychic events and structural differentiation form a single process. After looking into the parallelism between phenomenological and psychoanalytic views of time and differentiation, the author draws a distinction between two time categories: chronological versus actual. A clinical example is presented.
