Abstract
Low acceptance and adoption of farming technologies has been reported in various
studies from both developed and developing countries. In Tanzania, an attempt to
modernise cassava processing with modern technology has received low acceptance, thus,
low adoption rates. Previous studies on low adoption rates of the improved cassava
processing technology, however, have placed little emphasis on cognitive variables in
their conceptual models. Consequently, little is known of how technology adoption is
influenced by cognitive and behavioural factors. Through the psychological approach and
with application of the Social Cognitive Theory, this study sought to investigate cognitive
correlates of adoption of improved cassava processing technology among farmers in
Tanzania. This study specifically sought to; examine the relationship between the farmers’
attitudes towards improved cassava processing technology and its adoption; investigate
the relationship between the farmers’ perceived self-efficacy and adoption of the
improved cassava processing technology; examine the relationship between the farmers’
cognitive flexibility and adoption of improved cassava processing technology; and to
explain adoption of the improved cassava processing technology from cognitive
viewpoint when all intervening variables are put under control. Data were collected using
a cross–sectional survey among purposively selected sample of 360 respondents.
The sample included 181 (50.3%) males and 179 (49.7%) females from Mara, Mwanza
and Kagera regions in Tanzania. The study respondents were exposed to a questionnaire
with instruments that measured attitude, perceived self–efficacy, cognitive flexibility and
adoption of the improved cassava processing technology. The questionnaire also
comprised of socio-demographic variables such as age, sex, education level, training on
cassava processing technology, participation in other economic activities and intention to
adopt.
Data analysis was performed using the Statistical Package for Social Sciences
(SPSS V. 21). The Component Principle Analysis was used to check the psychometric
structures of the scales; Chi square for independence was used to check the association
between cognitive traits and adoption; The Pearson product moment correlation analysis
was performed to assess correlation among cognitive traits and between them and
adoption; and binary logistic analysis supplemented the analyses to explain adoption from
cognitive traits while controlling for other non–cognitive variables. Binary logistic
regression analysis indicated that cognitive traits such as attitude, perceived self–efficacy,
cognitive flexibility as well as one non–cognitive trait (training on improved cassava
processing technology) explained adoption of improved cassava processing technology.
The thesis indicates that each cognitive trait explain adoption in specific implementation
stage differently from the other. The thesis concludes that cognitive traits such as attitude
towards improved cassava processing technology, perceived self–efficacy and cognitive
flexibility partly explain adoption of the improved cassava processing technologies.
It is recommended to adoption promotion agents including the Government and nongovernment
stakeholders that from the onset of introduction of the cassava processing
technologies, training that is given to farmers should be tailored in a way that it may enlist
cognitive traits among the farmers. This may help improve adoption of improved cassava
processing technologies in all its implementation stages.
