One interaction between cognition + physiology in terms of behaviour (8/22)
One interaction between cognition + physiology in terms of behaviour (8/22)
INTRODUCTION
the BLA states that all cognitions, emotions and behaviours have a physiological basis
interaction between cognition + physiology in terms of the behaviour amnesia
amnesia = inability to retain / recall info from past experiences
has a physiological cause = brain damage to hippocampi region
physiology = internal, biological mechanisms of live-in organisms (way it functions)
cognition = mental processes: perception, attention, language, memory + thinking
affects cognition (memory)
CONCLUSION
physiology = damage to brain (hippocampus)
cognition = memory
supports idea of interaction between cognition + physiology in terms of amnesia
illustrates bi-directional relationship between physiological cause (brain damage) + cognitive process (memory)
damage to certain brain areas (hippocampus) affects memory in amnesia patients
MILNER & SCOVILLE (1957) -
HM
concluded - hippocampus is needed for memories to be transferred to long-term memory
reveals interaction between cognition (memory) + physiology (brain damage to hippocampus) in amnesia
HM had amnesia
after operation, HM = unable to create new memories
removes tissue from medial temporal lobe (MTL) - including hippocampus
HM had brain surgery to control epilepsy + stop seizures
study lacks population validity
SACKS (2007) -
CLIVE WEARING
caused memory impairment (effect on cognition)
couldn't transfer info from STM > LTM
on the cognitive process of memory
memory lasted 7 - 30 secs. + unable to form new memories
left him with serious brain damage to hippocampus (physiological cause)
highlights interaction between cognition + physiology in terms of amnesia
musician - got viral infection (encephalitis)
demonstrates effect of physiological cases in brain (damage to hippocampus shown on MRI's)
Clive - suffered from severe case of amnesia
