Catholicism,Protestantism, and Mexicanness on the US–Mexico border: discourses,narrative identities,habits, and affect

ABSTRACT

In Mexico, Catholicism and national identity are deeply intertwined through what we call a process of articulation. Thus, not surprisingly, despite the recent impressive growth of Protestantism in the nation, most people still believe that being Mexican and being Catholic are almost synonymous. Additionally, because the two identifications do not ‘cross each other’ (as the metaphor of intersectionality posits) but, instead, enter a very complex process of articulation in which each modifies the other, there is a particular way in which many Mexicans experience and perform their Catholicism, in the same vein that there is a particular way in which Catholics experience and perform their Mexicanness. Simultaneously, because neither nationality nor religion is narrated and/or performed in isolation to other forms of identification (e.g. race, ethnicity, region, gender) other possible identifications are also articulated or co-inform (in different ways) nationality and religion in the identitarian encounters that occur on the border. In the way people build their identifications around religion, narratives, practices, habits, affect, and emotions are continuously interrelated. We show that having an altar outside one’s house or making the sign of the cross on one’s body is both (depending on the unfolding of the social interactions and their patterns of relations) a non-linguistic discourse and a habit. We also show that their mere presence (in the case of altars) or performance (in the case of the sign of the cross) affect the people around the site or the performance, triggering complex emotions. That altar and sign of the cross can potentially be all these things simultaneously highlights their importance as ‘affective conductors’—stressing their significance as central objects in the intensification of relations that give new capacities to the entities involved in the patterns of relationship at play in the identitarian encounter at stake.     

Responsividad y condicionamiento semántico en relación con el ciclo menstrual

Resumen

El trabajo examina el efecto de cambios internos atribuibles al ciclo menstrual en la responsividad y condicionamiento psicofisiológico de un grupo de mujeres normales con ciclos naturales. Los sujetos fueron examinados Premenstrualmente (PM) o Intermenstrualmente (IM), utilizando como variables dependientes medidas psicofisiológicas (Conductancia de la Piel y Tasa Cardíaca) y cuestionarios. Los sujetos IM mostraron mayor responsividad y habituación en la actividad cardíaca y menores latencies de recuperación en la conductancia de la piel ante estimulación auditiva intensa, así como mayor condicionamiento en la conductancia de la piel (respuestas al segundo intervalo) que los sujetos PM. Las medidas actuales y retrospectivas de estados emocionales mostraron mayor afecto negativo (fatiga y tensión) en los sujetos PM y en l a fase premenstrual. Estos resultados son comparados con los de estudios similares realizados con pacientes fóbicas y son discutidos en términos de diferentes estados emocionales y de activación fisiológica asociados a las fases menstruales examinadas.     

When head is tempered by heart: Heart rate variability modulates perception of other-blame reducing anger

This study examined the relationship between heart rate variability (HRV), as an index of individual differences in emotion regulation, and perception of other-blame, as a mechanism of anger induction. The physiological responses were recorded while subjects read a story from a computer screen. The story narrated a negative event in self-referred way -dismissal from a job as the result of a colleague’s action- under conditions of intentionality versus non-intentionality. Cognitive and emotional variables were assessed by questionnaire immediately after the physiological test. The resulting structural model supports the conclusion that HRV exerts its regulatory influence directly on perception of other-blame rather than on emotion. In situations of intentionality, individuals with higher HRV make less extreme evaluation of the offender’s blame, versus those with lower HRV, thus leading to a reduction in anger reaction. These results suggest that HRV is a direct index of cognitive rather than emotional regulation.     

Food approach conditioning and discrimination learning using sound cues in benthic sharks

The marine environment is filled with biotic and abiotic sounds. Some of these sounds predict important events that influence fitness while others are unimportant. Individuals can learn specific sound cues and ‘soundscapes’ and use them for vital activities such as foraging, predator avoidance, communication and orientation. Most research with sounds in elasmobranchs has focused on hearing thresholds and attractiveness to sound sources, but very little is known about their abilities to learn about sounds, especially in benthic species. Here we investigated if juvenile Port Jackson sharks could learn to associate a musical stimulus with a food reward, discriminate between two distinct musical stimuli, and whether individual personality traits were linked to cognitive performance. Five out of eight sharks were successfully conditioned to associate a jazz song with a food reward delivered in a specific corner of the tank. We observed repeatable individual differences in activity and boldness in all eight sharks, but these personality traits were not linked to the learning performance assays we examined. These sharks were later trained in a discrimination task, where they had to distinguish between the same jazz and a novel classical music song, and swim to opposite corners of the tank according to the stimulus played. The sharks’ performance to the jazz stimulus declined to chance levels in the discrimination task. Interestingly, some sharks developed a strong side bias to the right, which in some cases was not the correct side for the jazz stimulus.     

The development and validation of Spanish versions of the State and Trait Food Cravings Questionnaires

OBJECTIVE: We developed and tested the psychometric properties of Spanish versions of the Trait and State Food Cravings Questionnaires (FCQ-T and FCQ-S respectively). METHOD: The instruments were translated and adapted to Spanish and administered to undergraduate students from a Southern university in Spain (N = 271). The data were analyzed using confirmatory factor analysis to compare the factor structure of the English and Spanish versions of both questionnaires. RESULTS: The factors structure of both questionnaires obtained excellent fit indices across their Spanish versions with the one exception that some factors of the FCQ-S were more highly intercorrelated among the Spanish sample than the American. DISCUSSION: This study supports the conceptualization of food cravings as universal multidimensional motivational states that can be reliably measured and supports the use of the Spanish versions of the FCQ.     

Effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle

Effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle. The risetime is a parametric characteristic of the eliciting stimulus frequently used to differentiate among psychophysiological reflexes. The aim of the present study was to examine the effect of manipulating the risetime of an acoustic stimulus on two protective reflexes: cardiac defense and motor startle. 100 participants underwent a psychophysiological reactivity test to five presentations of an intense acoustic stimulus (105 dB white noise) under one of five risetime conditions: 0, 24, 48, 96, and 240 ms. Total energy of the stimulus was controlled by increasing the base duration of the stimulus (1000 ms) by one third of the risetime. Results showed that risetime significantly affected motor startle but not cardiac defense. Startle amplitude decreased linearly with increasing risetime after 24 ms. On the other hand, repetition of the stimulus significantly affected cardiac defense but not motor startle. These results question the traditional differentiation between startle and defense based on risetime.     

Aphemia after a penetrating brain wound: A case study

The speech of a patient with aphemia (pure anarthria) resulting from a penetrating brain wound was studied using linguistic and acoustic observations as well as electromyographic recordings from four labial muscles. The results are discussed in relation to phonetic disintegration's syndrome and apraxia of speech which, respectively, enhance linguistic disorders and motor programming disturbance.     

The Aggression Questionnaire: a validation study in student samples

The goal of this study was to examine the psychometric properties of the Aggression Questionnaire (AQ) in Spain. The AQ is a 29-item instrument designed to measure the different dimensions of the hostility/anger/aggression construct. It consists of 4 subscales that assess: (a) anger, (b) hostility, (c) verbal aggression, and (d) physical aggression. In Study 1, reliability, construct validity, and convergent validity were evaluated in a group of 384 male and female university students. Test-retest reliability was evaluated using a group of 154 male and female university students. The results of the factor analysis were similar to the scale structure claimed for this instrument. The subscales also showed internal consistency and stability over time. The AQ and its subscales were also compared with the scales and subscales of the Spielberger State-Trait Anger Expression Inventory (STAXI), the Cook-Medley Hostility Scale (Ho), the Buss-Durkee Hostility Inventory (BDHI), and the Jenkins Activity Survey-Form H (JASE-H). The results show that the AQ evaluates some aspects of anger, such as Anger-Trait and Anger-Out, rather than other elements, such as Anger-In or Anger-State. In Study 2, two new male groups were used to evaluate the criterion validity of the AQ: 57 prison inmates and 93 university students, finding that this instrument discriminated between the scores obtained by common offenders and university students.
