Final answer:
Erikson's model of identity development has been criticized for potentially lacking empirical evidence, rather than being too focused on adulthood or having limited applicability to adolescence, as his theory does indeed address adolescent development extensively.
Step-by-step explanation:
Erik Erikson's model of identity development has faced criticism for various reasons throughout academic discussions. The phase most pertinent to adolescence is the identity versus role confusion stage, where adolescents question their purpose and strive to discover their personal identity. A criticism that relates directly to this stage may not be explicitly listed in the provided options; however, one possible criticism could be that Erikson's model may appear to lack empirical evidence supporting the distinct stages or could be deemed too focused on the individual without enough emphasis on societal or peer influences which are crucial during adolescence.
However, considering the other options provided such as being too focused on adulthood or having limited applicability to adolescence, they do not align well with Erikson's stages since his theory extensively addresses the adolescent phase. Thus, the most fitting criticism in context to the available options might be the suggestion that the model lacks empirical evidence, similar to some critiques of Piaget's stage-based approaches to cognitive development or Freud's theories, which were often criticized for not being empirically testable.
