A strength of episodic memory is that it is supported by case study evidence. |
HM & CLIVE WEARING: clinical studies of amnesia show difficulty of recalling past events. but their semantic memories were unaffected e.g. HM didn't recall stroking a dog earlier but didn't need the concept of 'dog' explaining. THEREFORE, supports that there are different memory stores in LTM as a damaged one left other unaffected. |
|
|
A strength is that brain scan studies show that there are different LTM stores. |
TULVING et al (1994): participants permed various memory tasks while their brains were scanned using a PET scanner. -episodic (right side) and semantic (left side) memories were in prefrontal cortex THEREFORE, shows physical reality in the brain to different types of LTM , confirmed by research studies, supports validity. |
|
|
A strength is that identifying different LTM stores has real-life application. |
BELLEVILLE et al (2006): found episodic memories can be improves in older people with cognitive impairments. THEREFORE, highlights benefit of distinguishing between different types of LTM - allows specific treatments to be developed. |
|
|
A limitation is there are problems with clinical evidence. |
HM & CLIVE WEARING: evidence often based on clinical evidence about memory damage. - lack of control variables THEREFORE, difficult to generalise from case studies to determine exact nature of LTM. |
|
|
A limitation of Tulving's approach is that there may only be two types of LTM. |
COHEN & SQUIRE (1980): argued episodic and semantic memories are stored together in one LTM store called declarative memory (memories that can be consciously recalled). BUT agree procedural is separate (non-declarative) THEREFORE, it's important to get semantic and episodic distinctions right as it influences how memory studies are conducted. |
