neuro-imaging research evidence

Tulving et al(1989) provides empirical research support that LTM has different subsystems. participants were asked to perform various tasks whilst being scanned by PET scans; Tulving found that episodic memories were recalled from the pre-frontal cortex and semantic memories from the posterior region of the brain. this shows how different types of LTM are found in different areas showing that it’s made up of different parts, also PET scans provide empirical data, therefore, this strengthens the support for types of LTM as the data is bias free and scientifically credible.

real life applications

research support for different types of LTM allows psychologists and clinicians to improve lives, as episodic memory is often the most affected. Belleville et al(2006) showed that episodic memory can be improved with those who have mild cognitive impairment, as trained participants perform better than the control group. this suggests that if psychologists know about the LTM stores, then programs can be made to improve lives.

overlap between semantic and episodic LTM stores

main issue is that the extent to which episodic and semantic stores are different is unclear, there’s a lot of overlap between the two systems. this is because we gain knowledge based on personal experiences, semantic memories can originate in episodic memories, therefore it’s unclear if semantic memory is a gradual transformation of episodic memory. as this is difficult to be sure of, it questions the validity of the theory as we can’t be sure of the internal validity of the research.

low population validity using case studies

limitation of the research is that it uses very small samples, case studies such as Clive Wearing are very useful for research, however, they are unique to the individual, which means that the findings cannot be generalised to the general population. this is an issue as evidence isn’t able to provide conclusions, meaning that the research lacks population validity.
