Early consequences of pre-Oedipal maternal deprivation

Abstract

The goal of this paper is to emphasize the early consequences of pre-Oedipal maternal deprivation, addressing the theories and techniques of the pioneers of child psychoanalysis. Even when these theories differ in their understanding and conceptualization of child psychopathology, their common denominator is that they believe in the importance of the infant’s early experiences of life and the necessary physical and emotional constancy of the mother–infant dyad. This paper approaches the different theories using three clinical vignettes. Through the synthesis of the psychoanalytic therapeutic process of a four-year-old boy, we can see how the conflicts and symptoms evolved and resolved in the course of five years of treatment, during which the boy’s behavior and productivity changed, allowing the treatment to come to an end. This boy was able to work through his traumatic separation experience in analysis, and to develop more mature defense mechanisms that led him toward a better adjustment to his environment. We can conclude that the early interruption of maternal care led to serious symptoms in this child’s behavior and mental organization. If these difficulties had not been addressed in time, the symptoms would have gone on to become severe.     

Air pollution, cognitive deficits and brain abnormalities: a pilot study with children and dogs

Exposure to air pollution is associated with neuroinflammation in healthy children and dogs in Mexico City. Comparative studies were carried out in healthy children and young dogs similarly exposed to ambient pollution in Mexico City. Children from Mexico City (n: 55) and a low polluted city (n:18) underwent psychometric testing and brain magnetic resonance imaging MRI. Seven healthy young dogs with similar exposure to Mexico City air pollution had brain MRI, measurement of mRNA abundance of two inflammatory genes cyclooxygenase-2, and interleukin 1 beta in target brain areas, and histopathological evaluation of brain tissue. Children with no known risk factors for neurological or cognitive disorders residing in a polluted urban environment exhibited significant deficits in a combination of fluid and crystallized cognition tasks. Fifty-six percent of Mexico City children tested showed prefrontal white matter hyperintense lesions and similar lesions were observed in dogs (57%). Exposed dogs had frontal lesions with vascular subcortical pathology associated with neuroinflammation, enlarged Virchow-Robin spaces, gliosis, and ultrafine particulate matter deposition. Based on the MRI findings, the prefrontal cortex was a target anatomical region in Mexico City children and its damage could have contributed to their cognitive dysfunction. The present work presents a groundbreaking, interdisciplinary methodology for addressing relationships between environmental pollution, structural brain alterations by MRI, and cognitive deficits/delays in healthy children.     

The Role of Simple Emotion Recognition Skills among School Aged Boys at Risk of ADHD

Poor social skills and behavioral problems are a major component of ADHD. The different explanations offered so far, such as cognitive deficits and deficient self regulation, have not been able fully to account for the various aspects of the social dysfunction, suggesting that other mechanisms might underlay this impairment. Our study sought to assess the emotion recognition of Israeli boys at risk of ADHD, and to evaluate its associations with their social skills. A group of 111 boys (grades 4 and 5) were assigned to an At-risk (n=50) and a control (n=61) group based on their scores in an ADHD symptoms questionnaire. The two groups were matched on age, socio-economic status and class and school environment. Group comparisons revealed that compared to their non-At-risk counterparts, At-risk boys have impaired emotion recognition. Finally, multiple groups Structural Equation Modeling analyses (SEM) demonstrated that emotion misrecognition plays a significant role in the At-risk children's social functioning and behavioral problems compared to its role in the social competence and behavioral problems among the comparison group. Implications for the understanding and treatment of social skills problems among children at risk of ADHD are proposed.     

Big Picture,Bad Outcomes: When Visual Perspectives Harm Health Goal Pursuit

People often fail to achieve health goals, which compromises their well‐being. Prior research suggests that seeing events through an observer's eyes (i.e., adopting a third‐person perspective) should facilitate goal pursuit. However, we find that third‐person perspectives discourage goal‐consistent intentions and behavior for health goals when goal centrality is low (i.e., the goal is peripheral to one's self‐concept). In Experiment 1, people who adopted a third‐person perspective chose more sugary foods if they considered a healthy eating goal to be more peripheral to the self. Experiment 2 examines why a third‐person perspective can hinder goal pursuit; it encourages a breakdown in implemental thinking which, in turn, increases negative self‐conscious emotions. While high goal centrality buffers people from negative effects on goal intentions, low centrality does not. Experiment 3 demonstrates that this effect is robust when goal centrality is manipulated. We recommend that consumers pursuing health goals (and individuals who support them) exercise caution when employing perspective‐based strategies, as they may backfire for people at greatest risk of goal abandonment.

Oceans of stimuli: an individual-based model to assess the role of olfactory cues and local enhancement in seabirds’ foraging behaviour

Animal Cognition - Oceans are extremely dynamic environments, which poses challenges for top-predators such as seabirds to find food resources. Yet, seabirds evolved sensorial abilities (olfactory...
