1. Some of the research and studies is unethical - in the study by Bandura, children were shown aggressive behaviour that may affect the participants behaviour once the study had finished
2. The approach focuses mainly on childhood development (Piaget's stages of development)
3. The developmental approach suggests our behaviour is determined by our up-bringing and is less governed by our own free will - nature v nurture debate.
4. Lab studies can have low ecological validity - Bandura for example, children would rarely, if at all, be shown violent aggression towards a Bobo doll in real life.
5. Case studies are difficult to generalise - The case study of Little Hans form Freud's study is unique to the "dreams" and phobias of Hans .. these results and conclusions won't be able to be applied easily to another individual
