Determinantes psicológicos e situacionais do comportamento de conserva??o de água: um modelo estrutural
Corral-Verdugo, Víctor;
Estudos de Psicologia (Natal) , 2003, DOI: 10.1590/S1413-294X2003000200006
Abstract: a model of psychological and situational factors affecting water consumption was specified and tested. 500 individuals living at two cities of sonora, mexico were the subjects for this study. one of those cities experienced a chronic scarcity of water, while the other one had a sufficient supply of the liquid. direct observations of individuals' water consumption (in different activities) and of their conservation skills were conducted. also, their utilitarian beliefs regarding the use of water, and their conservation motives were assessed using a questionnaire. the possession of furniture for using water was considered as one situational factor promoting water consumption, and water scarcity was considered as a potential inhibitor of that consumption. these variables were incorporated in a structural model. results of this model revealed that water consumption was significantly and positively influenced by utilitarian beliefs and the possession of furniture, while conservation motives, conservation skills and water scarcity inhibited such consumption. conservation motives were positively affected by water scarcity and conservation skills, and negatively influenced by utilitarian beliefs. significant covariances between the determinants of water consumption revealed the interdependence of situational and psychological variables affecting water use.
Psicologia Ambiental: objeto, "realidades" sócio-físicas e vis?es culturais de intera??es ambiente-comportamento
Corral-Verdugo, Víctor;
Psicologia USP , 2005, DOI: 10.1590/S0103-65642005000100009
Abstract: the author defines the object of environmental psychology as the mutual influence of environmental and behavioral factors on the analysis of specific problems and their solutions. as for the dimensions of reality, he firstly discusses the topic physical environment and the conditions that should be taken into account when one studies environmental behavior. secondly, he discusses the socio-cultural aspects of our surroundings and how they influence both our lay and scientific views of the world, arguing that, as different cultures produce different environmental views, these can manifest in specific environmental psychologies, but this does not mean the idea of a universal environmental psychology should be abandoned.
Consideration of Immediate and Future Consequences in Accepting and Responding to Anthropogenic Climate Change  [PDF]
Victor Corral-Verdugo, Joaquin Caso-Niebla, Cesar Tapia-Fonllem, Martha Frías-Armenta
Psychology (PSYCH) , 2017, DOI: 10.4236/psych.2017.810101
Abstract: Decreasing greenhouse gas emissions (climate change mitigation) is one of the most important types of pro-environmental behavior. Greenhouse gases have been repeatedly cited as a leading cause of climate change (CC). However, before engaging in CC mitigation behaviors, individuals must accept the reality of CC. Few studies addressing the influence of individual time perspective on climate change mitigation have been found. No study investigating the relationship between time perspectives and acceptance of the reality of CC exists. This study was aimed at filling that research gap. The study examines the impact of consideration of immediate and distant consequences of behavior on individual acceptance of the reality of CC and commitment to engage in CC mitigation behaviors. Two-hundred-and-forty-five undergraduate students responded to an instrument investigating those variables. A structural-equation model revealed that consideration of distant consequences affects acceptance of CC, but considering immediate consequences do not influence that acceptance. Accepting that CC is real affects the commitment to act pro-environmentally, which in turn influences CC mitigation commitment. Consideration of distant consequences also positively affects willingness to engage in CC mitigation; yet, consideration of immediate consequences produced no effect on that commitment.
Intrinsic Motives of Autonomy, Self-Efficacy, and Satisfaction Associated with Two Instances of Sustainable Behavior: Frugality and Equity  [PDF]
Víctor Corral-Verdugo, Daniel González-Lomelí, Marisol Rascón-Cruz, Víctor O. Corral-Frías
Psychology (PSYCH) , 2016, DOI: 10.4236/psych.2016.75068

This paper explores the relationship between sustainable behavior, indicated by frugal and equitable actions, and three intrinsic motives: satisfaction, autonomy and self-efficacy. One-hundred and seventy-three undergraduates at a Mexican university responded to a questionnaire investigating their sustainable actions and the intrinsic repercussions derived from those actions. Using structural equations, a model is specified and tested, which reveals the presence of a higher-order factor (sustainable behavior) subjacent to a high and significant covariance between frugal and equitable behaviors. The resulting higher-order-factor, in turn, significantly predicts the report of feelings of satisfaction, autonomy, and self-efficacy. These findings are in line with the idea that sustainable behavior is to a good extent self-determined through the operation of intrinsic consequences, which instigate people’s pro-social and pro-environmental actions.

Condi??es para o estudo do comportamento pró-ambiental
Corral-Verdugo, Víctor;Pinheiro, José Q.;
Estudos de Psicologia (Natal) , 1999, DOI: 10.1590/S1413-294X1999000100002
Abstract: the current status of pro-environmental behavior (cpa) research is reviewed, emphasizing the conditions that, according to the authors, could result in obstacles or advantages to such kind of investigation. among those conditions we discuss the role played by the quantity and quality of predictive variáveis upon the explanatory power of models, the problem of self-reports as measurement technique of cpa, the effect of research contexts,
El rol de los eventos antecedentes y consecuentes en la conducta sustentable
Corral Verdugo, Víctor;Domínguez Guedea, Rosario Leticia;
Revista mexicana de análisis de la conducta , 2011, DOI: 10.5514/rmac.v37.i2.26137
Abstract: a review of the pertinent literature shows that the interest of most environmental psychologists focuses on studying the antecedent events (i.e., historical-and-situational dispositional variables) that promote sustainable behavior. this behavior is defined as the set of actions aimed at conserving the earth's natural and socio-cultural resources, so that the wellbeing of present and future generations can be guaranteed. although several psychological frameworks -eminently the behaviorist- acknowledge the importance of the positive consequent variables (i.e., positive repercussions) on the display and maintenance of sustainable behavior, a limited interest in their study is detected, especially in regard to the role played by intrinsic consequences. since a number of those consequences have been recently reported in research reports, this paper discusses how the positive repercussions might promote the display of sustainable lifestyles and how the antecedent events could be connected with the consequent ones, so that a higher likelihood of generating pro-environmental and pro-social behaviors among citizens may be achieved. the paper also reviews a possible way of connecting individual proenvironmental behavior with the cultural practice of sustainable actions.
Percepción de riesgos, conducta proambiental y variables demográficas en una comunidad de Sonora, México
Daniel González Lomelí,Martha Frías Armenta,Victor Corral Verdugo
Región y sociedad , 2003,
Abstract: Se estudiaron las respuestas que dieron 200 hab itantes de una ciudad del norte mexicano a un instrumento que investigaba el grado de riesgo percibido en 84 situaciones. éstas incluían peligros potenciales debidos a la naturaleza, uso de tecnologías, conductas criminales y comportamientos personales de riesgo. Los sujetos calificaron qué tan peligrosa era cada situación para el medio ambiente físico (riesgo ambiental), para la sociedad (riesgo social) y para sí mismos (riesgo personal) . Se examinaron ,asimismo, conductas de cuidado del medio ambiente reportadas por los sujetos, y algunas variables demográficas. De acuerdo con tres modelos de regresión múltiple, la percepción de riesgos ambientales parece desembocar en conductas de cuidado del ambiente, lo cual no sucede con la percepción de riesgos sociales y personales. En los tres casos, se encontró que las personas de mayor edad y con ingresos económicos más bajos perciben un mayor riesgo ambiental, social y personal. Se analizan estos resultados en el marco de posibles estrategias de prevención y afrontamiento de riesgos para el ambiente, la sociedad y los individuos en particular.
Hopf Bifurcation Analysis of the Repressilator Model  [PDF]
Anael Verdugo
American Journal of Computational Mathematics (AJCM) , 2018, DOI: 10.4236/ajcm.2018.82011
Abstract: The repressilator is a genetic network that exhibits oscillations. The net-work is formed of three genes, each of which represses each other cyclically, creating a negative feedback loop with nonlinear interactions. In this work we present a computational bifurcation analysis of the mathematical model of the repressilator. We show that the steady state undergoes a transition from stable to unstable giving rise to a stable limit-cycle in a Hopf bifurcation. The nonlinear analysis involves a center manifold reduction on the six-dimensional system, which yields closed form expressions for the frequency and amplitude of the oscillation born at the Hopf. A parameter study then shows how the dynamics of the system are influenced for different parameter values and their associated biological significance.
Análisis de características morfológicas y funcionales de competencias de lectura y escritura en ni?os de primaria
Sánchez Hernández, Beatriz A.;Bazán Ramírez, Aldo;Corral Verdugo, Vìctor;
Revista mexicana de análisis de la conducta , 2009,
Abstract: by the application of multitrait-multimethod strategy (campbell y fiske 1959; widaman, 1985) two morphologic and functional characteristics models of writing and reading have been tested. one hundred and seventy nine children registered in primary school (first, second and third grade) answered 18 tasks classified on a morphologic and on a functional criterion. the models we tested show goodness of fit, but the model that specifies the existence of ave functional factors doesn't show good divergent validity, while the model that specifies three functional factors shows convergent validity as well as divergent validity. the two models indicate the contribution of the two dimensions specified in the performance of the children. additionally, children's mean responses are identified as a complex index of answers. children in third grade have higher performance than children in first grade, these differences are significant. the results are discussed in terms of utility, the contribution of the analytical strategy used for the validation of tasks, and the pertinence of the use of the functional taxonomy of behavior (ribes y lópez, 1985), in the description of the psychological character of reading and writing.
Un registro observacional del consumo individual de agua: Aplicaciones a la investigación de la conducta sustentable
Corral Verdugo, Víctor;Fraijo Sing, Blanca S.;Tapia Fonllem, César;
Revista mexicana de análisis de la conducta , 2008,
Abstract: an observational technique for measuring individual water consumption is presented, which assesses diverse domestic uses of water. the recording is conducted by previously trained housewives in an attempt to obtain a reliable, valid assessment that minimizes the inconveniences of classical observational techniques, such as the intrusion from observers and the subsequent reactivity of the observed people. the water consumption of 510 individuals was recorded, computing through three days in a week the time invested by the observer and two other persons at her household in washing dishes, taking a shower, watering plants, tooth- brushing, and watering the sidewalk in front of their households. results of the recording indicated stability and internal consistency of the measures, revealing reliability of the instrument. a confirmatory factor analysis indicated evidence of convergent construct validity, which was reinforced by a significant correlation between the observations and the meter-recording of water consumption. also, an evidence of concurrent validity was obtained when correlating these observations with scales assessing utilitarian and ecological beliefs regarding water.
