Visual Memory Improvement In Recognition, Allison Prandl Jan 2012

Visual Memory Improvement In Recognition, Allison Prandl

Theses : Honours

Fluid intelligence and working memory has been improved by training on a visual working memory n-back task (Jaeggi, Buschkuehl, Jonides & Perrig, 2008). The present study investigated whether n-back training can improve visual memory using a test of visual recognition. A sample of 47 participants were trained for 20 days on either the single n-back task (n = 26) or a general knowledge and vocabulary task (n = 21). The results showed that training using the single n-back task did not significantly increase scores on a test of visual recognition when compared with general knowledge and vocabulary training. However, when initial scores were ...

Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) and active control (n = 21) groups; and engaged in 20 daily, 20-minute training sessions over a 30-day period using either a single n-back task, or a combination of two general knowledge tasks respectively. STM and WM psychometric tests were administered before and after the 30-day training process. No significant difference was found between pre- and post-training STM or WM scores, indicating both constructs were unlikely near transfer mechanisms for single nback training. There ...
