Five perceived attributes of innovations (Rogers):

• Four attributes are positively correlated with the rate of adoption:
• Relative Advantage ($+$)
• Compatibility ($+$)
• Trialability ($+$)
• Observability ($+$)
• Only Complexity (the degree to which an innovation is perceived as relatively difficult to understand and use) is negatively related to its rate of adoption.
• The greater the complexity, the slower the adoption rate.

Y.P. Singh and Udai Pareek's Indian adoption model (1965):

• Singh established that in farming communities, perceived Need precedes awareness of specific technologies:
• Need (B)
• Awareness and Interest (A)
• Deliberation and Trial (D)
• Evaluation (E)
• Adoption (C)
• Unlike Western models that start with Awareness, Singh recognized felt Need as the initial impetus for information seeking.
  Sequence: (B) $\rightarrow$ (A) $\rightarrow$ (D) $\rightarrow$ (E) $\rightarrow$ (C).

Everett Rogers' Generalizations on communication channels across adopter categories:

• Generalization 1: Mass media channels are relatively more important for earlier adopters than for later adopters, whereas interpersonal channels are relatively more important for later adopters. Statement (I) claims the opposite, so it is incorrect.
• Generalization 2: Cosmopolite channels are relatively more important for earlier adopters than for later adopters, whereas localite channels are relatively more important for later adopters. Statement (II) claims the opposite, so it is incorrect.
• Therefore, both Statement (I) and Statement (II) are incorrect.
