Synthesis of autonomous robots through evolution

Evolutionary robotics is the attempt to develop robots through a self-organized process based on artificial evolution. This approach stresses the importance of the study of systems that have a body and that are situated in a physical environment, and which autonomously develop their own skills in close interaction with the environment. In this review we briefly illustrate the method and the main concept of evolutionary robotics, and examine the most significant contribution in this area. We also discuss some of the contributions that this research area is making to the foundational debate in cognitive science.     

Interfacial waves between two magneto-electro-elastic half-spaces with magneto-electro-mechanical imperfect interface

The propagation of shear horizontal waves between the interface of two magneto-electro-elastic materials with an magneto-electro-mechanical imperfect contact has been studied. Mechanical, electrical and magnetical imperfections are modelled by means of a spring, a capacitor and an inductor, respectively. A general expression for the dispersion relation is given in an explicit form. Some limit cases are analysed in detail. The influence of imperfect contacts is shown in some numerical results.     

Hypnotic assessment based on the Recurrence Quantification Analysis of EEG recorded in the ordinary state of consciousness

The cerebral cortical correlates of the susceptibility to hypnosis in the ordinary states of consciousness have not been clarified. Aim of the study was to characterize the EEG dynamics of subjects with high (highs) and low hypnotisability (lows) through the non-linear method of Recurrence Quantification Analysis (RQA). The EEG of 16 males – 8 highs and 8 lows – was monitored for 1 min without instructions other than keeping the eyes closed, being silent and avoiding movements (short resting), and during 15 min of simple relaxation, that is with the instruction to relax at their best. Highs and lows were compared on the RQA measures of Determinism (DET) and Entropy (ENT), which are related to the signal determinism and complexity. In the short resting condition discriminant analysis could classify highs and lows on the basis of DET and ENT values at temporo-parietal sites. Many differences in DET and all differences in ENT disappeared during simple relaxation, although DET still separated the two groups in the earliest 6 min of relaxation at temporo-parietal sites. Our RQA based approach allows to develop computer-based methods of hypnotic assessment using short-lasting, single channel EEG recordings analyzed through standard mathematical methods.     

Incremental Validity of Alexithymia, Emotional Coping and Humor Style on Happiness and Psychological Well-Being

This study attempts to ascertain whether alexithymia, suppression and reappraisal coping, and humor styles account for incremental variance in happiness (Lyubomirsky’s scale) and psychological well-being (Ryff’s scale), after controlling for Big Five traits and emotional positivity ratio of previous day’s mood. A total of 355 psychology undergraduates (72 % women) responded to measures of each construct, and two hierarchical multiple regressions were carried out for happiness and psychological well-being. The Big Five were entered in the first regression block, alexithymia was entered in a second block, and affiliative, self-enhancing, aggressive and self-defeating humor style, reappraisal and suppression coping were entered in the third block, and previous day’s mood in the last step. Alexithymia accounted for a small proportion of variance in psychological well-being, controlling for the Big Five traits. Suppression and affiliative, self-enhancing and self-defeating humor explained a complementary amount of variance in happiness and psychological well-being, controlling for the previous day’s mood, confirming the association of emotional regulation and affect with judgments of happiness and well-being. Taking into account humor and suppression, the multivariate association of alexithymia disappears. Results suggest that low suppression, low self-critical use of humor and affiliative humor are correlates of psychological well-being, whereas self-enhancing humor and low suppression are correlates of happiness, playing a mediational role between personality traits and well-being.     

ANOTHER HISTORY: FAMILY,NATION AND THE REMEMBRANCE OF THE EGYPTIAN JEWISH PAST IN CONTEMPORARY ISRAELI LITERATURE

In this article I will focus on how Egyptian Jews who migrated to Israel after 1948 and their descendants remember Egypt and how they situate themselves vis-à-vis Israeli society and culture. I will base my analysis on three semi-autobiographical novels published between 2003 and 2011 by Israeli writers of Egyptian descent belonging to three subsequent generations: Baderekh la'itztadion by Yitzhak Gormezano Goren, Kol tze‘adenu by Ronit Matalon, and Yolanda by Moshe Sakal. By analysing specific passages from these books, I will argue that even after the decline of the Jewish presence in Egypt in the 1950s, the cultural and social worlds to which their families belonged did not vanish completely but, rather, struggled for survival at a very intimate level. This ultimately produced a multifaceted archive in which the written narrative of the family's past became an alternative homeland where historical memories and fictional details are inextricably blended.     

Correction to: Effects of Parental Acceptance-Rejection on Children’s Internalizing and Externalizing Behaviors: A Longitudinal,Multicultural Study

Journal of Child and Family Studies -     

Introduction

This symposium presents the work of the Italian legal philosopher, Ferrajoli, to the English speaking public. Ferrajoli’s work offers a reflection on law and the constitutional democratic state from a post-positivist perspective, applying the axiomatic method to the theory of law and democracy. Besides his systematic approach, Ferrajoli’s theory is remarkable for a number of original and interesting reflections that he offers on the relationship between normativity and facticity, and on how to reconcile foundamental rights and democracy. In both respects, his work has similarities in scope, if not in approach and not always in substance, with that of Habermas.     

Gender Effects in Information Processing on a Nonverbal Decoding Task

Women typically outperform men on the ability to assess other people??s nonverbal behavior. This difference might occur because women are taught to be more sensitive to emotional and nonverbal cues at a very early age compared to men. As a consequence, women might use a more favorable cognitive processing style than men during nonverbal decoding. The present study investigated whether this gender difference is due to the use of different cognitive information processing styles (global or local). Participants (N?=?137) were Swiss undergraduate students that were randomly assigned to either a global (focusing on the whole) or a local (focusing on details) priming of information processing style, or to a control group. They then performed a nonverbal decoding task. Results showed that compared to the control group, local priming had beneficial and global priming detrimental effects for nonverbal decoding accuracy. This was due to an improved performance in men after the local priming; women??s performance was not significantly affected by the local priming. Global priming increased nonverbal decoding accuracy in men and decreased performance in women. We conclude that women already use the more beneficial local processing style by default and that men??s performance can be boosted when providing them a processing strategy.     

A Computational Evaluation of Two Models of Retrieval Processes in Sentence Processing in Aphasia

Can sentence comprehension impairments in aphasia be explained by difficulties arising from dependency completion processes in parsing? Two distinct models of dependency completion difficulty are investigated, the Lewis and Vasishth (2005) activation-based model and the direct-access model (DA; McElree, 2000). These models' predictive performance is compared using data from individuals with aphasia (IWAs) and control participants. The data are from a self-paced listening task involving subject and object relative clauses. The relative predictive performance of the models is evaluated using k-fold cross-validation. For both IWAs and controls, the activation-based model furnishes a somewhat better quantitative fit to the data than the DA. Model comparisons using Bayes factors show that, assuming an activation-based model, intermittent deficiencies may be the best explanation for the cause of impairments in IWAs, although slowed syntax and lexical delayed access may also play a role. This is the first computational evaluation of different models of dependency completion using data from impaired and unimpaired individuals. This evaluation develops a systematic approach that can be used to quantitatively compare the predictions of competing models of language processing.     

War experiences and emerging rights claims in postwar former Yugoslavia: The role of generalized conflict exposure and collective anomie

Violent conflicts have often been observed to generate social environments in which human rights violations are more easily tolerated and legitimized. However, recent research has documented cases in which communities exposed to violence react with increased condemnations of human rights violations. In this article, we focus on the distinction between generalized and particularized violence. Our findings show that, in the postwar ex-Yugoslavia context, when local communities have been exposed to violence that was generalized across different ethno-national groups, they strongly condemn human rights violations. Multilevel structural equation models show that the relationship between generalized victimization and the condemnation of human rights violations is mediated by a collective sense of anomie. The processes that move from collective exposure to violence to the collective reaffirmation of human rights are more likely to unfold in communities where violence transcended group boundaries than in communities where particular groups were disproportionately affected by the violence.
