Character of inhibitory control ability and the relationship with craving of mobile phone dependence college students / 中国学校卫生

Objective@#This aim of the study is to analyze the general and specific inhibition control of college students who have mobile phone dependence and their craving for mobile phone after the wastage of inhibition control resource, and to provide a reference for the intervention.@*Methods@#The Mobile Phone Addiction Tendency Scale was used to screen 40 mobile phone dependence and 40 non-dependence college students, who were divided into two groups completed two conditions of Numerical Stroop Task with and without mobile phone ringing sound interference. Craving for mobile phone before and after the Numerical Stroop Task was assessed.@*Results@#Mobile phone dependence group had significantly more Stroop interference scores than mobile phone normal use group under the two conditions( F =19.34, P <0.01).After completing the Numerical Stroop Task under the interference condition, mobile phone dependence group experienced a significant boost craving of mobile phone ( t =-6.02, P <0.01). The scores of craving for mobile phones after the Numerical Stroop Task had significant positive relationships with Stroop interference scores( r =0.51, 0.51 , P <0.05).@*Conclusion@#The mobile phone dependence college students have poor inhibition control, inhibitory control which might associate with increase of craving for mobile phone.

El paradigma stop signal como medida de inhibición conductual / The Stop Signal Paradigm: a measure of behavioral inhibition

El Paradigma de la Señal de Parar, Stop Signal en inglés, es uno de los procedimientos más utilizados para medir el control inhibitorio. Su amplia difusión se explica por dos motivos: su extensa aplicación en el ámbito de la neuropsicología clínica y, porque aporta un índice -el tiempo de frenado- que no se obtiene con otros paradigmas o procedimientos. Esta medida, refiere al tiempo que necesita el individuo para inhibir una respuesta preponderante. El cálculo del índice deriva de un modelo clásico de inhibición, el "Modelo de Carrera de Caballos". Sin embargo, el modelo no ha sido suficientemente difundido en nuestro medio, debido a la complejidad de los análisis matemáticos de base y a que la bibliografía disponible en español en este tema es casi inexistente. Por ello, el objetivo de este trabajo es efectuar una revisión sobre este método y presentar algunas de sus aplicaciones en la neuropsicología clínica y de la psicopatología, tales como para el trabajo con pacientes con trastorno bsesivo compulsivo, adicciones, y trastorno de atención, entre otros.

The Stop Signal Paradigm is one of the most used procedures for measuring the inhibitory control. Their widespread diffusion is due to two reasons: its extensive application in the field of clinical neuropsychology and because it provides an index-braking time-that is not accessible with other paradigms or procedures. This index is defined as the time required for inhibiting a dominant response. The method used to calculate this measure is based on a classical model of inhibition: the "Horse Race Model". However, their diffusion is limited in our environment because the available literature in Spanish is poor due to the complexity of mathematical analysis involved. Therefore, the aim of this work is to carry out a review of this method and present some of its applications in the field of clinical neuropsychology and psychopathology, such as working with patients with obsessive compulsive disorder, addictions, and attention disorder, among others.
