This experimental investigation examined short term memory capacity differences in males and females. This was done by exposing subjects to random and sequenced visual, haptic and auditory sequences. It also explored the effect of memory retention techniques on the capacity of short term memory. The results obtained show that sequences are more effectively recalled when shown visually to a subject and in accordance with Miller’s number short term memory is limited to 7 plus/minus 2 items. Results also indicated that women had overall better memory retention than males. Also, when retention enhancing techniques were utilised, the frequency of successful sequence recall also increased. Furthermore it was found that auditory pathways were the most successful, followed by visual then haptic. INTRODUCTION Overtime, organisms have been able to adapt and develop in a range of diverse environments as a result of their ability to maintain homeostasis. Homeostasis is the tendency of anatomical, behavioural and physiological systems to maintain internal stability, owing to the coordinated response of its parts to any situation or stimulus that would tend to disturb its normal condition or function. (1) A major physiological system that works in maintaining homeostasis in animals, specifically humans, is the nervous system. The nervous system consists of a vast network of interconnecting neurons which transmit electronic signals throughout the body. All neurons relay information to
