ABSTRACT
Resumen El objetivo de este trabajo es estudiar la relación entre los estilos de humor adaptativos (humor afiliativo y humor mejoramiento personal) y desadaptativos (humor agresivo y humor descalificación personal) propuestos por Martin (2003), y las conductas agresivas físicas y verbales. Se trabajó con una muestra de 100 adolescentes argentinos, entre 16 y 18 años, de ambos sexos, quienes respondieron dos escalas: el Cuestionario de Agresividad Física y Verbal (Caprara y Pastorelli, 1993, versión española de del Barrio, Moreno Rosset, López y Martínez, 2001), y la versión adaptada al español por Cayssials (2004) de la Escala de Estilos de Humor (Martin, 2003). Los resultados indican que el humor agresivo predice positivamente las conductas agresivas en general, tanto verbales como físicas, mientras que el estilo de humor de mejoramiento personal mitiga las conductas agresivas evaluadas en general y las conductas agresivas verbales. Por último, las conductas agresivas físicas únicamente fueron predichas por el estilo de humor agresivo.
Abstract The sense of humor gives a new perspective of life by turning the person into a spectator of what is happening, being able to laugh at oneself and to what happens to one. Because of that, it is considered that humor allows us to face problematic situations in a different way. Carbelo and Jáuregui (2006) argue that sense of humor is not a mere remedy to prevent or help overcome disease; instead, it has the capacity to promote greater well-being, enjoyment of life, growth towards greater humanity and fulfillment. These same authors add that sense of humor is a unique trait of the human species and it is possessed by all human beings of different cultures (Carbelo y Jáuregui, 2006). While each culture has its own rules about which facts or situations may be the object or cause of humor, "both humor and laughter are universal" (Cassaretto y Martínez, 2009, p. 289). Although humor has been associated with psychological, physical and social well-being, not all research show consistent results. This is because sense of humor does not imply only positive components, but also negative components (Martin, 2003; Cassaretto y Martínez, 2009). In general, the different studies carried out have perceived sense of humor as a positive feature with the potential to generate positive effects. However, there are negative elements of humor that have a negative correlation with psychological well-being (Martin, 2003; Grimshaw, Kirsh, Kuiper y Leite, 2004). Therefore, it is important to be able to consider the sense of humor not as a one-dimensional construct (taking into account only its positive components), but to be able to focus on a multi-dimensional approach capable of considering all the characteristics and consequences -positive and negative- of it. Martin (2003) postulates that humor is a personality trait composed of either healthy or adaptive components and of unhealthy or unadaptable components. This author proposes the following classification: Adaptive humor is formed by affiliative humor (the tendency to say funny things, to make jokes, and spontaneous and witty jokes to amuse other people) and self-enhancing humor (it implies having fun with the incongruities of life even in adversity and using humor as a strategy to face the vicissitudes), and unadaptive humor is formed by aggressive humor (the tendency to use humor for the purpose of criticizing or manipulating others by resorting to sarcasm, bothering with jokes, ridiculing others) and self-defeating humor (people who use this kind of humor are self-deprecating, make or say funny things at the expense of themselves and laugh with others while ridiculing or belittling). The aim of this work is to study the relationship between these two types of humor and physical and verbal aggressive behaviors. We worked with a sample of 100 adolescents from Argentina of both sexes, aged between 16 and 18 years, of the middle socioeconomic strata of Buenos Aires, Argentina. All participants responded to two scales: the questionnaire of physical and Verbal aggression (Caprara y Pastorelli, 1993, Spanish version of Barrio, Moreno Rosset, López Martínez, 2001), and the version adapted to Spanish by Cayssials (2004) of the scale of humor styles (Martin, 2003). The results indicate that aggressive humor positively predicts aggressive behaviors evaluated in a general way, and aggressive behaviors verbal and physical evaluated specifically. On the other hand, personal improvement humor style mitigates general aggressive behaviors and verbal aggression specifically. Finally, aggressive physical behaviors were only predicted by the aggressive humor style.
ABSTRACT
Los accidentes de tránsito son un fenómeno complejo, resultado de factores ambientales, vehiculares y humanos, y una de las principales causas de muerte a nivel mundial. La inatenciónes un factor primordial que contribuye a los accidentes de tránsito. El objetivo del presente trabajo fue analizar la relación entre la atención según el modelo de redes atencionales de Posner (1994) y la propensión a cometer errores relacionados con la inatención durante la conducción vehicular. La muestra estuvo compuesta por 70 participantes, edades entre 19 y 59 años, ambos géneros, 9.83 años de experticia como promedio. Se utilizó el Cuestionario de Experiencias durante la conducción (ARDES-ERIC),Test de Redes Atencionales (ANT) y un cuestionario sociodemográfico. Los resultados indican que existe una correlación significativa en-tre el tiempo de reacción (TR) total y la propensión a cometer errores durante la conducción. La interacción entre la experticia y el TR total sobre la propensión a cometer errores fue significativa. La atención ejecutiva tuvo un efecto significativo sobre la propensión a cometer errores y la dimensión de control. El modelo que incluye la red de orientación y tiempos de reacción explicó el 20% de la propensión a cometer errores en la conducción. Una alta orientación está asociada con una baja propensión a cometer errores, y los tiempos de reacción más lentos están relacionados con altos errores de conducción. Los resultados son consistentes con estudios previos y aportan nueva evidencia sobre el rol de los tiempos de reacción y redes atencionales en interacción con variables sociodemográficas y experticia sobre la propensión a cometer errores en la conducción.
Traffic accidents are a complex phenomenon resulting from a combination of environmental, vehicular and human factors, which have become one of the leading causes of death worldwide. Inattention is one of the main factors contributing to traffic accidents. The aim was to analyze the relationships between attention and the error proneness while driving. Posner´s model states three attentional networks quantified by reaction time measures: orienting, alerting, and executive control (Posner, 1994; Fan et al., 2002). Orienting is responsible for the information selection. Alerting facilitates achieving and sustaining an alert state. Executive attention controls interference and solves conflicts between possible responses. Driver inattention was conceptualized from a perspective of individual differences as a "tendency or personal propensity of drivers to experience attentional lapses" (Ledesma et al., 2010, 2015). This tendency canbe expressed at different levels of driving behavior: operational level, maneuvering, and strategic level (Michon, 1985). The sample consisted of 70 drivers from Buenos Aires (Argentina), both genders (57% female; Mage = 29.29; SD =9.258; Mexperience years = 9.83; SD = 8.861), inclusion criteria: driver's license, regular driving during the last two months (at least once a week), normal vision, and at least one year of driving experience. Factorial design 2 (low- high for each of the attentional networks) x 2 (gender). Measures: ARDES-ERIC (Ledesma et al., 2010): a 19-items self-report instrument to evaluate individual differences in the propensity to commit attentional failures while driving and can be classified according to the driving task le-vel at which they occur (navigation, maneuve-ring, or control) (Alpha: .88; navigation Alpha:.744, maneuvering Alpha: .727, and control Alpha: .770), Attention Network Test (Fan et al., 2002) to measure three attentional networks: alerting (Alpha: .52), orienting (Alpha: .61), and executive attention (Alpha: .77) and RT attention (Alpha: .87) and a sociodemographic questionnaire that includes question about driver behavior (e.g. frequency and experience). Results show that no relationship was detected between ARDES and age but there are significant correlation between ARDES and driving task level with Global Reaction Time (Global RT). ANOVA results show a significant interaction between Global Reaction Times and expertise on driving errors [F(1,64) = 7.746; p < .01; η² =.108]. Experts drivers with low RT (lower processing speed) have a higher propensity to commit attentional failures while driving (Mlowrt =35.58; SD = 13.08; Mhighrt = 26.95; SD = 5.21).There are no interactions between Global RT, sociodemographics variables (age, gender), and driving frequency on propensity to commiterrors. Global RT correlates significantly withtotal score driving errors (r= .373, p < .01). Executive Attention has a significant effect on total driving errors [F(1,66)= 3.760; p = .05; η² =.054], and only on the Control Dimension [F(1,66) =7.889; p < .01; η² =.124]. There are no effects of Alerting and Orienting on total driving errors neither on each dimension of driving. A linear regression model involving the Orientation network and Global RT explained the 20% of the total variance of the error proneness while driving (R² adjusted= .203). A higher level of Orienting attention is related to a lower propensity to commit errors (ß= -.332; p < .01), and alower processing speed (higher Global RT) explained higher driving errors (ß = .242; p <.05). Results are consistent with previous studies (López-Ramón et al., 2011) and provide new evidence about the role of executive control on specific dimensions of driving. In addition, the findings provide new evidence on the role of reaction times and attentional networks, in interaction with sociodemographic variables and expertise on the propensity to commit errors while driving. Limitations and theoretical-practical implications will be discussed.
ABSTRACT
Abstract Microsatellites are valuable molecular markers for evolutionary and ecological studies. Next generation sequencing is responsible for the increasing number of microsatellites for non-model species. Penguins of the Pygoscelis genus are comprised of three species: Adélie (P. adeliae), Chinstrap (P. antarcticus) and Gentoo penguin (P. papua), all distributed around Antarctica and the sub-Antarctic. The species have been affected differently by climate change, and the use of microsatellite markers will be crucial to monitor population dynamics. We characterized a large set of genome-wide microsatellites and evaluated polymorphisms in all three species. SOLiD reads were generated from the libraries of each species, identifying a large amount of microsatellite loci: 33,677, 35,265 and 42,057 for P. adeliae, P. antarcticus and P. papua, respectively. A large number of dinucleotide (66,139), trinucleotide (29,490) and tetranucleotide (11,849) microsatellites are described. Microsatellite abundance, diversity and orthology were characterized in penguin genomes. We evaluated polymorphisms in 170 tetranucleotide loci, obtaining 34 polymorphic loci in at least one species and 15 polymorphic loci in all three species, which allow to perform comparative studies. Polymorphic markers presented here enable a number of ecological, population, individual identification, parentage and evolutionary studies of Pygoscelis, with potential use in other penguin species.
