This paper is concerned with intercultural relationships within the trigenerational family. As part of our study of sociostructural changes affecting the family, we have looked at these relationships from a basis of the concepts: generation gap and seriality between generations. The information reported in this paper was obtained from twenty inter-generational triads (ten female, six male, four mixed) who were given a series of highly structured and open ended questions by trained interviewers. The results showed significant differences in the definitions of culture given by the three generations. The most important result in analysing ‘taste cultures’ and cultural activities within trigenerational families is that within the trigenerational family there are varying relationship structures and that these are perceived differently by the different generations. This is attributed to an overall process of individualisation in society. The findings indicate that similar taste cultures and shared activities in grandparent-grandchild generations are not common and that consecutive generations resemble each other more in tastes and activities. In general, the position of the old in relation to the youngest generation can be described as remote. Grandparents are not important in the cultural life of young adult grandchildren and vice versa. On the basis of our findings, it would appear that the family is declining as a factor in the sociocultural integration of the elderly.
