The influence of indirect and direct emotional processing on memory for facial expressions

We used the remember-know procedure (Tulving, 1985 ) to test the behavioural expression of memory following indirect and direct forms of emotional processing at encoding. Participants (N=32) viewed a series of facial expressions (happy, fearful, angry, and neutral) while performing tasks involving either indirect (gender discrimination) or direct (emotion discrimination) emotion processing. After a delay, participants completed a surprise recognition memory test. Our results revealed that indirect encoding of emotion produced enhanced memory for fearful faces whereas direct encoding of emotion produced enhanced memory for angry faces. In contrast, happy faces were better remembered than neutral faces after both indirect and direct encoding tasks. These findings suggest that fearful and angry faces benefit from a recollective advantage when they are encoded in a way that is consistent with the predictive nature of their threat. We propose that the broad memory advantage for happy faces may reflect a form of cognitive flexibility that is specific to positive emotions.     

Logical dynamics of belief change in the community

In this paper we explore the relationship between norms of belief revision that may be adopted by members of a community and the resulting dynamic properties of the distribution of beliefs across that community. We show that at a qualitative level many aspects of social belief change can be obtained from a very simple model, which we call ‘threshold influence’. In particular, we focus on the question of what makes the beliefs of a community stable under various dynamical situations. We also consider refinements and alternatives to the ‘threshold’ model, the most significant of which is to consider changes to plausibility judgements rather than mere beliefs. We show first that some such change is mandated by difficult problems with belief-based dynamics related to the need to decide on an order in which different beliefs are considered. Secondly, we show that the resulting plausibility-based account results in a deterministic dynamical system that is non-deterministic at the level of beliefs.     

Investigating the relationship between social behaviors and phonological awareness in preschool children

Purpose

This study examined the longitudinal effects of social behaviors in predicting phonological awareness outcomes in 4-year-old children.

Method

One hundred two children (52 boys, 50 girls) were recruited from 11 schools serving low-income neighborhoods in a large metropolitan city and were assessed at the beginning and end of the preschool year. All children received assessments of their phonological awareness skills, expressive vocabulary, non-verbal IQ, and teachers completed behavioral ratings at pretest. At the end of the academic year, children participated in tests of phonological awareness using standardized assessments.

Results

The results of a multiple regression analysis indicated that being excluded by peers contributed up to 3% of the variance in negatively predicting phonological awareness outcomes after controlling for initial phonological awareness skills, expressive vocabulary, and cognition which is a small effect size.

Conclusion

Early peer exclusion can impact negatively on the acquisition of phonological awareness skills in 4-year-old children in preschool. The results of this study suggest that a child's overall behavioral competence and how they are treated by the peer group may play an important role in their ease of academic skill attainment. Given the link between peer exclusion and difficulties with phonological awareness outcomes, additional professional development programs that provide teachers with strategies to create inclusive classrooms may be warranted in preventing against the emergence of maladaptive behaviors at first entry into formal schooling.     

About hemispheric differences in the processing of temporal intervals

The purpose of the present study was to identify differences between cerebral hemispheres for processing temporal intervals ranging from .9 to 1.4 s. The intervals to be judged were marked by series of brief visual signals located in the left or the right visual field. Series of three (two standards and one comparison) or five intervals (four standards and one comparison), marked by sequences of 4 or 6 signals, were compared. While discrimination, as estimated by d', was significantly better in the 4-standard than in the 2-standard condition when stimuli were presented in the left visual field (LVF), this number-of-standard effect on discrimination varied with the difficulty levels when the signals were presented in the LVF. Moreover, the discrimination levels were constant for the different base durations with stimuli presented in the LVF, but not with stimuli presented in the right visual field. This article discusses the implication of these findings for the study of hemispheric dominance for temporal processing and for a single-clock hypothesis.     

Forgivingness and Satisfaction with Life

The present study was aimed at examining the link between satisfaction with life and forgivingness using a dispositional measurement for forgiveness. The participants were 810 adolescent and adults living in France, and 192 college students living in Portugal. They were presented with the Forgivingness questionnaire (Mullet, E., J. Barros, L. Frongia, V. Usai and F. Neto: 2003, Journal of Personality 71, pp. 1–19), and the Satisfaction With Life Scale (Diener, E., R.J. Emmons, R.J. Larsen and S. Griffin: 1985, Journal of Personality Assessment 49, pp. 71–75). The link between satisfaction with life and all three components of forgivingness (enduring resentment, sensitivity to circumstances, and overall willingness to forgive) was weak, and most of the time non-significant. This result is consistent with previous findings showing that (a) forgiving an offense to an offender does not result in a strong increase in overall satisfaction, and (b) strictly self-referential traits (e.g., self-esteem and loneliness) are typically not linked with forgivingness. Possible reasons why forgivingness and satisfaction with life are not linked are discussed.     

Expressive language and prosocial behaviour in early childhood: Longitudinal associations in the UK Millennium Cohort Study

Background: Early childhood is a crucial period for language development and building social skills. While distinct, these two processes may impact upon each other.

Aims: The current study aimed to identify the directional associations between expressive language ability and prosocial behaviour between three and five years of age.

Methods: Participants included 14, 004 children and their families enrolled in the UK Millennium Cohort Study. Children’s expressive language and prosocial behaviour were assessed at three and five years of age utilizing standardized assessments and parent reports. Cross-lagged models were used for data analysis.

Results: Better expressive language at three years was associated with increased prosocial behaviour by five years. No support for the inverse direction of association was found.

Conclusions: Children’s early ability to effectively express themselves with others may help in building better social relationships by entry into formal schooling. Programming efforts that are tailored towards enhancing positive behavioural growth and social skills in the toddler years are likely to be effective when expressive language is also a targeted component of the toddler’s skill development.     

Everything Else Being Equal: A Modal Logic for <Emphasis Type="Italic">Ceteris Paribus</Emphasis> Preferences

This paper presents a new modal logic for ceteris paribus preferences understood in the sense of “all other things being equal”. This reading goes back to the seminal work of Von Wright in the early 1960’s and has returned in computer science in the 1990’s and in more abstract “dependency logics” today. We show how it differs from ceteris paribus as “all other things being normal”, which is used in contexts with preference defeaters. We provide a semantic analysis and several completeness theorems. We show how our system links up with Von Wright’s work, and how it applies to game-theoretic solution concepts, to agenda setting in investigation, and to preference change. We finally consider its relation with infinitary modal logics.     

Winnicott’s foundation for the basic concepts of Freud’s metapsychology?1

In a recent paper, Fulgencio shows how Winnicott rejected the basic speculative concepts of Freud’s metapsychology – Trieb, psychical apparatus and libido – and replaced them with non-speculative concepts that promoted a factual theorization. In this paper, the author examines some of Winnicott’s concepts and attempts to demonstrate how, rather than replacing Freud’s concepts, he provides a factual foundation for the metapsychology in the double dependence of the infant in care. Freud never actually disregards the necessity of early mothering but he takes it for granted. By differentiating between ego needs and id needs, ego-relatedness and id-relatedness, object-mother and environment-mother, Winnicott attempts to theorize what Freud takes for granted: the function of the holding environment as a framework for id-experiences and the function of object-presenting as a condition of reality-testing. Furthermore, by differentiating between pure male and pure female elements, he is also able to construct a highly speculative theorization in order to distinguish two basic principles: doing and being. Although the death drive is clearly rejected, this rejection follows from his theorization of double dependence. Consequently, the author suggests that Winnicott did not discard metapsychological concepts but theorized the conditions for using both these and the intrapsychic topography.     

The influence of indirect and direct emotional processing on memory for facial expressions

We used the Remember–Know procedure (Tulving, 1985 Tulving, E. 1985. Memory and consciousness. Canadian Psychology, 26: 1–12. [Crossref], [Web of Science ®] , [Google Scholar]) to test the behavioural expression of memory following indirect and direct forms of emotional processing at encoding. Participants (N=32) viewed a series of facial expressions (happy, fearful, angry, and neutral) while performing tasks involving either indirect (gender discrimination) or direct (emotion discrimination) emotion processing. After a delay, participants completed a surprise recognition memory test. Our results revealed that indirect encoding of emotion produced enhanced memory for fearful faces whereas direct encoding of emotion produced enhanced memory for angry faces. In contrast, happy faces were better remembered than neutral faces after both indirect and direct encoding tasks. These findings suggest that fearful and angry faces benefit from a recollective advantage when they are encoded in a way that is consistent with the predictive nature of their threat. We propose that the broad memory advantage for happy faces may reflect a form of cognitive flexibility that is specific to positive emotions.     

Characterization of room-temperature plastic deformation of ß-Si3N4 by atomic force microscopy and transmission electron microscopy

Dislocation microstructures induced by room-temperature microhardness tests have been investigated in silicon nitride. Surface analysis of the residual indent by atomic force microscopy reveals intragranular slip bands and demonstrates that room-temperature plastic deformation involves dislocation motion as well as cross-slip events. Cross-slip events have been found to occur between {1010} prismatic planes. Transmission electron microscopy shows that dislocations have a Burgers vector b = [0001] and are located along the screw direction. Based on these observations, specific dislocation core configurations are discussed.
