Preventing the detrimental effect of posttraumatic stress in young children: The role of theory of mind in the aftermath of a natural disaster

We conducted a field study to test whether parents' negative reactions to a natural disaster affected children's reactions, together with the factors buffering this negative influence. Specifically, we examined whether parents' posttraumatic stress symptoms following an earthquake were associated with children's posttraumatic symptoms and their use of negative coping strategies. Theory of mind (ToM) was tested as the factor allowing children to reduce the detrimental effects of posttraumatic stress symptoms on negative coping. Hypotheses were tested in a sample of elementary school children and their parents in the aftermath of the earthquakes that struck Northern Italy in 2012. Results revealed that mothers' (but not fathers') posttraumatic stress symptoms were positively associated with children's posttraumatic stress symptoms, which acted as mediator on the use of negative coping strategies by children, but only among children with low ToM abilities. We discuss the theoretical and practical implications of findings.     

Verbal facilitation effects instead of verbal overshadowing in face memory of 4- to 6-year olds

Research on eye witness memory in older children and adults revealed that verbally describing unfamiliar faces impairs later recognition of these faces, known as the “verbal overshadowing effect”. The aim of this study was to investigate whether a verbal overshadowing effect occurs in 4- to 6-year olds, too, and whether visualization (i.e., drawing the seen face) might elicit a visual overshadowing effect. Instead of a verbal overshadowing effect, a verbal facilitation effect was revealed with verbal intelligence being a significant predictor for recognition accuracy in the verbalization group but not in the control group. No effect of visualization was observed on recognition accuracy. Potential explanations for the results are discussed.     

Elucidating The Etiology and Nature of Beliefs about Parenting Styles

This study was designed to investigate relationships among self‐reported and spouse‐reported beliefs about parenting styles, the characteristics of the individuals manifesting these styles, and the contextual characteristics of parenting. Demographic characteristics, life circumstances, family functioning, personality traits, ability indices, and parenting‐styles indicators were collected from a sample of 452 women and 293 men, all of whom were raising adolescents in contemporary Russia. Of the families studied, 275 were intact (i.e. consisted of married and cohabiting couples). It was found that individual characteristics and contextual characteristics (e.g. family functioning) together predicted about 20% of the variance in reported beliefs about parental styles of responsiveness and demandingness. Moreover, these variables discriminated about 65% of the parents reporting indulging, neglectful, authoritarian or authoritative beliefs about parenting. The percentage of explained variance doubled when beliefs about parenting styles of partners were placed in the model. Thus, in attempts to understand the etiology of parents’ beliefs about parenting styles, more attention should be given to beliefs about parenting styles of their spouses. It might be that beliefs about parenting styles emerge as a structure shared by spouses; they are mediated, but not solely determined, by the individual characteristics of parents and their children.     

Learning and foraging efficiency in German cockroaches, Blattella germanica (L.) (Insecta: Dictyoptera)

We analysed, under laboratory test conditions, how German cockroach larvae oriented their outgoing foraging trip from their shelter. Our results stressed the importance of external factors, like availability and spatial distribution of food sources, in the choice of a foraging strategy within their home range. When food sources were randomly distributed, larvae adopted a random food search strategy. When food distribution was spatially predictable and reliable, cockroaches were able to relate the presence of food with a landmark during a 3-day training period and to develop an oriented search strategy. Cockroaches were able to associate learned spatial information about their home range to the presence of food resources and then to improve their foraging efficiency. However, conflict experiments revealed that detection of food odour overrode learned landmark cues. Received: 16 October 1999 / Accepted after revision: 18 July 2000     

Applications Of Paraconsistency In Data And Knowledge Bases

The study of paraconsistent logic as a branch of mathematics and logic has been pioneered by Newton da Costa. With the growing advent of distributed and often inconsistent databases over the last ten years, there has been growing interest in paraconsistency amongst researchers in databases and knowledge bases. In this paper, we provide a brief survey of work in paraconsistent databases and knowledge bases affected by Newton da Costa's important and lasting contributions to the field.     

Gerry Adams and the Northern Ireland Peace Process

This research note uses Hermann's personality-at-a-distance (PAD) method and applies it to negotiating behavior. Gerry Adams's personality and its effect upon his negotiating behavior in the current peace process in Northern Ireland is used as an illustration of the expanded application of PAD in a negotiating context.     

Anxiety and Threat Perception Abnormalities in Normal Children

The current study examined the relationship between childhood anxiety and threat perception abnormalities. Children (N = 105) were exposed to stories reflecting three types of anxiety: social anxiety, separation anxiety, and generalized anxiety. From children's reactions to the stories, a number of threat perception indices were derived. Children's level of anxiety was assessed by means of questionnaires and a structured diagnostic interview. Results indicated that high levels of anxiety, as measured by questionnaires and interview, were accompanied by a high frequency of threat perception, high ratings of threat, a high frequency of threatening interpretations, high levels of negative feelings and cognitions, and an early detection of threat. Furthermore, results seemed to suggest that threat perception abnormalities were mediated by children's general level of anxiety rather than by levels of specific anxiety symptoms.
