When measuring inverse effectiveness it is important to ensure that we make use of grey scaled stimuli and short durations for the project tasks. The use of lateralized stimulation does not prohibit against the transfer of information to the brain. The task of undertaking the lateralization process does not require the use of greyscale or color. The output of any system could be used in through holistic representations or representations which are bi-lateral of contra-lateral (Balota, 2004). Capabilities of accessing each hemisphere in isolation or through processing in each different hemisphere among people are challenging.
Holistic processing could be undertaken using varied forms of facial expression. In these instances, the brain will take time to recognize differences in expression if similar expressions are used. For instance, if two happy facial expressions belonging to different people are distorted then the brain can process the composite expression as happy. However, the brain through the right hemisphere might recognize that both distorted faces are not similar. This experiment re-affirms the thoughts and research undertaken by Calder in the field of cognitive psychology (Kellogg, 2003).
Composite figures tend to tap on figural processing since the objects are arranged to come up with a composite face with one expression. In the process of making out the faces of the subjects used in the images, the participants were engaged in using the different facial expressions. However, none of them used these expressions in the task of facial recognition. Due to this, we can conclude that facial expressions are processed in terms of their configurable make-up (Galotti, 2010). For instance, the position of the mouth, nose or mouth in displaying emotions is coded according to each participant.
It is also true to conclude that making use of different facial expressions can be used in coming up with one composite expression. In this case, we can use a different expression to come with one totally new expression.
