Mapas «usted está aquí»: importancia de la alineación con el ambiente y puntos de correspondencia mapa-medio

Resumen

Este estudio se centra en la influencia de la alineación mapa/medio y del número de puntos de correspondencia mapa/medio sobre la interpretación de los mapas «Usted está aquí». Se llevó a cabo en el Campus Universitario de Santiago de Compostela, utilizándose un diseño factorial 2 x 2. Cada sujeto tenía que localizar un objeto en un mapa y desplazarse hacia él. Se utilizaron cuatro versiones diferentes de mapas y, como variables dependientes, una amplia gama de índices (tiempo de observación del mapa, tiempo invertido en llegar al punto-meta, éxito o fracaso en la tarea, diversas medidas del trayecto, legibilidad percibida del mapa, seguridad y grado de dificultad subjetiva de la tarea).

Los resultados indcaron que los sujetos tardan menos tiempo en interpretar y localizar un objetivo en un mapa cuando está alineado con el ambiente, lo perciben como más legible que uno no alienado, y seleccionan un trayecto más adecuado hacia el punto-meta.     

Coping profiles characterize individual flourishing,languishing, and depression

Abstract

According to the broaden-and-build theory of positive emotions, negative emotions narrow one's thought–action repertoire. In contrast, positive emotions have a broadening effect, expanding cognitive capacity, increasing potential coping strategies that come to mind, and enhancing decision-making, reaction, and adaptation to adversity. Fredrickson and Losada determined that a positivity ratio – the ratio of experienced positive to negative emotions – at or above 2.9 promotes human flourishing. A ratio below 2.9 is indicative of languishing individuals, whereas a ratio below 1.0 is a marker of depression. This study examined whether adaptive and maladaptive coping profiles differentiated those who flourish, languish, or are depressed in two convenience samples – military spouses (n =367) and public school teachers (n=267). Results were consistent with the theoretical predictions, as coping profiles of the groups differed significantly, with flourishing individuals favoring adaptive coping strategies more than those who were languishing or depressed. Conversely, depressed individuals reported greater use of maladaptive coping strategies than those who were languishing or flourishing. These results provide further empirical support for the mathematical model of Fredrickson and Losada, as the set of positivity criteria were predictive of coping profiles in two samples where successful coping and adaptation are important.     

The influence of semantic property and grammatical class on semantic selection

Research to-date has not successfully demonstrated consistent neural distinctions for different types of ambiguity or explored the effect of grammatical class on semantic selection. We conducted a relatedness judgment task using event-related functional magnetic resonance imaging (fMRI) to further explore these topics. Participants judged relatedness within word pairs. Consistent and inconsistent conditions were included along with filler items. Imaging results revealed a main effect of ambiguity in the dorsolateral prefrontal cortex (DLPFC) and parietal cortices. A main effect of grammatical class was observed in the parahippocampal and lingual gyri, and a main effect of consistency was found in the DLPFC, ventrolateral prefrontal cortex (VLPFC) and occipital cortices. Interactions among these factors were observed in the cingulate gyrus and motor cortices in addition to the DLPFC. These results suggest that both ambiguity type and grammatical class modulate semantic selection through different neural regions.     

The Confluence of Psychiatric Symptoms and Neurodegenerative Disease: Impact on Genetic Counseling

Hereditary neurodegenerative diseases can present with a psychiatric prodrome that overlaps with psychiatric symptoms that are not primary to these diseases. When individuals present for predictive testing while experiencing such symptoms, clinicians including genetic counselors, must proceed with caution and evaluate each situation on a case-by-case basis. Legitimate reasons may exist for moving forward with testing. Additionally predicting the consequences of testing is unrealistic so that the clinicians must do their best to prepare patients for both positive and negative results. A multidisciplinary team following the Huntington disease protocol remains the gold standard care for predictive testing for such patients. We discuss 3 case histories that demonstrate the complex nature of genetic counseling and testing in the presence of psychiatric symptoms, whether emanating from the disease itself or the results of living in an affected family.     

Body Objectification, Self-Esteem, and Relationship Satisfaction: A Comparison of Exotic Dancers and College Women

We examined body objectification, self-esteem, and relationship satisfaction differences between college women and exotic dancers and the relationships among these measures for both groups. Forty-three college women and 40 female exotic dancers completed a questionnaire that assessed each of these constructs. Relative to college women, exotic dancers reported less relationship satisfaction, more body surveillance, and a greater prioritizing of body attractiveness over physical competence. Relationship satisfaction and the prioritizing of appearance over physical competence varied for the heterosexual and bisexual dancers. For exotic dancers, the body objectification measures of surveillance and shame were negatively, and body control was positively, related to self-esteem; body shame was negatively related to relationship satisfaction. For college women, higher levels of body surveillance and body shame were associated with higher prioritizing of physical attractiveness relative to physical competence.     

Inequities in Under-Five Mortality in Nigeria: Differentials by Religious Affiliation of the Mother

Observations in Nigeria have indicated polio vaccination refusal related to religion that ultimately affected child morbidity and mortality. This study assessed the role of religion in under-five (0–59 months) mortality using a cross-sectional, nationally representative sample of 7,620 women aged 15–49 years from the 2003 Nigeria Demographic and Health Survey and included 6,029 children. Results show that mother’s affiliation to Traditional indigenous religion is significantly associated with increased under-five mortality. Multivariable modelling demonstrated that this association is explained by differential use of maternal and child health services, specifically attendance to prenatal care. To reduce child health inequity, these results need to be incorporated in the formulation of child health policies geared towards achieving a high degree of attendance to prenatal care, irrespective of religious affiliation.
