Behavioural Problems in Children with Headache and Maternal Stress: Is Children's Attachment Security a Protective Factor?

Headache is a potentially disabling condition involving enduring pain that negatively influences the quality of family life. Behavioural problems are more common in children with headache and are potentially associated with higher levels of parental stress. The aim of this study was to evaluate the extent to which children's behavioural problems were associated with maternal stress and how the child's perception of security in the maternal attachment relationship moderates this association. Seventy‐one school‐aged children with headache (headache group (HG), age M = 9.8 years old, SD = 1.3) and 71 children from a low‐risk normative population (control group (CG), age M = 9.2 years old, SD = 1) and their mothers were involved in the study. Mothers' reports of children's behavioural problems were associated with higher maternal stress in the caring task both in the HG and in the CG. Results also showed that the HG was more at risk for behavioural problems, whereas no difference between groups was detected for parenting stress and for attachment insecurity. In children with headache, perception of attachment security decreased the strength of the association between maternal stress and externalizing behavioural problems. Secure attachment may provide children with headache and their parents with support in managing the negative emotions that arise in the context of significant health issues. Implications for practice are discussed. Copyright © 2015 John Wiley & Sons, Ltd.     

Multiple and Counterstereotypic Categorization of Immigrants: The Moderating Role of Political Orientation on Interventions to Reduce Prejudice

Multiple and counterstereotypic categorization of outgroup members reduces prejudice towards them. The present research addresses, for the first time, the role of political orientation in moderating the impact of these strategies on prejudice reduction. Given that right‐wingers have very likely a higher need for cognitive closure compared to left‐wingers and thus may be less tolerant to social diversity, for them, increasing the complexity of outgroup members through counterstereotypic versus stereotypic or multiple versus simple categorizations should be a less effective strategy of prejudice reduction than it is for left‐wingers and moderate individuals. Results using Romanians and immigrants as outgroup targets for Italian participants supported our prediction. Further, we found that the effect of prejudice reduction was explained by the sequential mediation of increased individuation of immigrants and reduced sense of threat from them. Implications of the interplay between multiple categorization and political orientation are discussed.     

Neuropsychology of Environmental Navigation in Humans: Review and Meta-Analysis of fMRI Studies in Healthy Participants

In the past 20 years, many studies in the cognitive neurosciences have analyzed human ability to navigate in recently learned and familiar environments by investigating the cognitive processes involved in successful navigation. In this study, we reviewed the main experimental paradigms and made a cognitive-oriented meta-analysis of fMRI studies of human navigation to underline the importance of the experimental designs and cognitive tasks used to assess navigational skills. We performed a general activation likelihood estimation (ALE) meta-analysis of 66 fMRI experiments to identify the neural substrates underpinning general aspects of human navigation. Four individual ALE analyses were performed to identify the neural substrates of different experimental paradigms (i.e., familiar vs. recently learned environments) and different navigational strategies (allocentric vs. egocentric). Results of the general ALE analysis highlighted a wide network of areas with clusters in the occipital, parietal, frontal and temporal lobes, especially in the parahippocampal cortex. Familiar environments seem to be processed by an extended temporal-frontal network, whereas recently learned environments require activation in the parahippocampal cortex and the parietal and occipital lobes. Allocentric strategy is subtended by the same areas as egocentric strategy, but the latter elicits greater activation in the right precuneus, middle occipital lobe and angular gyrus. Our results suggest that different neural correlates are involved in recalling a well-learned or recently acquired environment and that different networks of areas subtend egocentric and allocentric strategies.     

Plural <Emphasis Type="Italic">Grundgesetze</Emphasis>

PG (Plural Grundgesetze) is a predicative monadic second-order system which exploits the notion of plural quantification and a few Fregean devices, among which a formulation of the infamous Basic Law V. It is shown that second-order Peano arithmetic can be derived in PG. I also investigate the philosophical issue of predicativism connected to PG. In particular, as predicativism about concepts seems rather un-Fregean, I analyse whether there is a way to make predicativism compatible with Frege’s logicism.     

Are people with high and low mental rotation abilities differently susceptible to the alignment effect?

We investigated whether the alignment effect (Levine et al, 1982 Journal of Experimental Psychology: General 111 157-175) is influenced by mental rotation abilities. In two experiments, groups of undergraduate students with high and low performance in mental rotation tasks were required to study either schematic (experiment 1) or more complex (experiment 2) maps, and to perform a number of pointing tasks adopting a perspective which could be aligned, misaligned (45 degrees, 135 degrees), or counteraligned (180 degrees) with the perspective assumed during learning. Cognitive styles in spatial representation have also been considered. Results of experiment 1 show that people with low performance in mental rotation tasks prefer to adopt a representation of space focused more on landmarks. Their performance in the pointing tasks depends on the alignment conditions, with more errors in the counteraligned condition followed by the two misaligned and aligned ones. In contrast to this, high-ability mental rotators prefer survey and route spatial representations and are affected only by the aligned and non-aligned conditions. In the second experiment, practice was studied as a function of mental rotation and alignment. The group high in mental rotation ability was found to be free from the alignment effect in the pointing tasks performed after the final of four learning phases.     

Confirmatory factor analyses of DSM-IV Cluster C personality disorder criteria

Notwithstanding its research and clinical relevance, the dimensionality and validity of the DSM-IV avoidant, dependent, and obsessive-compulsive personality disorders (PDs) criteria is still a largely unexplored topic. The aim of this study was to test the factor structure for DSM-IV Cluster C PD criteria in a sample of 641 consecutively admitted outpatients. Factor analysis results suggested that avoidant, dependent, and obsessive-compulsive PDs share a common latent dimension, and supported the three-factor structure of both observer and self-report ratings of DSM-IV Cluster C PD criteria. The pattern of factor loadings, however, was different from the one expected according to the DSM-IV classification.     

Hypnotic suggestion modulates cognitive conflict: the case of the flanker compatibility effect

The present work was aimed at investigating whether the flanker compatibility effect can be eliminated by means of a posthypnotic suggestion influencing attentional focusing. In Experiment 1, participants who scored high and low on hypnotic susceptibility performed the flanker compatibility task when naturally awake and when under a posthypnotic suggestion aimed at increasing the target's discriminability from the flankers. Results showed that the posthypnotic suggestion effectively eliminated the flanker compatibility effect in highly susceptible participants, whereas low-susceptibility participants did not show any reduction in the effect. In Experiment 2, highly susceptible participants performed the task after receiving a suggestion but without the induction of hypnosis. Results showed that the suggestion alone was not sufficient to reduce the flanker compatibility effect. These results support the view that in highly susceptible participants, hypnotic suggestion can influence the ability to focus on relevant information.     

Negative automaintenance omission training is effective

Twelve pigeons were exposed to negative automaintenance contingencies for 17-27 sessions immediately after brief (14-16 sessions) or extended (168-237 sessions) exposure to positive automaintenance contingencies, or after 4-10 sessions of instrumental training. In all conditions, negative automaintenance contingencies virtually eliminated responding, reducing response rates to an average 1.3 responses per min. This reduction in response rate was validated by a model of transition between early and late response rates that assumed exponential transition of rates from one set of contingencies to the next. The model faithfully reproduced cumulative records, and yielded estimates of terminal rates under negative automaintenance that were close to operant level.     

Three-month-olds' visual preference for faces and its underlying visual processing mechanisms

This study was aimed at investigating the face preference phenomenon and its underlying mechanisms at 3 months of age. Using an eye-tracker apparatus, Experiment 1 demonstrated that 3-month-olds prefer natural face images to unnatural ones, replicating and extending previous evidence obtained with schematic facelike stimuli. Experiments 2 and 3 showed that the general mechanisms that induce face preference in newborns could not explain the same phenomenon at 3 months of age, when infants are attracted by perceptual cues more specific to faces. This suggests that signs of a process of cognitive specialization are already present in 3-month-olds' visual behavior toward faces.
