Language Generativity,Response Generalization,and Derived Relational Responding

Language generativity can be described as the ability to produce sentences never before said, and to understand sentences never before heard. One process often cited as underlying language generativity is response generalization. However, though the latter seems to promise a technical understanding of the former at a process level, an investigation of definitions and approaches to the term “response generalization” that appear in the literature suggests that it does not do so. We argue that a more promising candidate for the role of key process underlying language generativity is derived relational responding. We introduce the latter concept and describe empirical research showing its connection with language. We subsequently present a relational frame theory (RFT) conceptualization of derived relations as contextually controlled generalized relational responding. We then review a series of recent studies on derived manding in developmentally delayed children and adults that arguably demonstrate the applied utility of a derived relations-based approach with respect to the phenomenon of generative language.     

‘There is Nothing that is Difficult’: History and Hardship on and after the Ho Chi Minh Trail in North Vietnam

The North Vietnamese Army considered the Ho Chi Minh Trail a key part of their victory during the Vietnam War against the United States. The trail was often defended by encouraging large numbers of lowland Vietnamese villagers to show their patriotism by moving to the uplands. Ho Chi Minh himself said of the enormous task of making the trail, ‘There is nothing that is difficult’. Based on fieldwork in Ha Tinh province, where the trail began, this paper addresses what happened after the war to the many migrants who had moved to defend and support the trail. After 1975, many families had expected increased government support as a thank you for their tremendous patriotism and sacrifice during the war. Instead, they became gradually disillusioned with collective farming, and later with the retreat of state services, and incidences of social protest and discontent have been increasingly clamorous in the post-war era.
