accidental biological changes also support basic biological mechanisms in the mind. Social pre-wiring hypothesis Twin studies have resulted in important evidence against the tabula rasa model of the mind, specifically, of social behaviour. The social pre-wiring hypothesis (also informally known as "wired to be social") refers to the ontogeny of social interaction. The theory questions whether there is a propensity to socially oriented action already present before birth. Research in the theory concludes that newborns are born into the world with a unique genetic wiring to be social. Circumstantial evidence supporting the social pre-wiring hypothesis can be revealed when examining newborns' behaviour. Newborns, not even hours after birth, have been found to display a preparedness for social interaction. This preparedness is expressed in ways such as their imitation of facial gestures. This observed behaviour cannot be attributed to any current form of socialization or social construction. Rather, newborns most likely inherit to some extent social behaviour and identity through genetics. Principal evidence of this theory is uncovered by examining twin pregnancies. The main argument is, if there are social behaviours that are inherited and developed before birth, then one should expect twin fetuses to engage in some form of social interaction before they are born. Thus, ten fetuses were analyzed over a period of time using ultrasound techniques. Using kinematic analysis, the results of the experiment were that the twin fetuses would interact with each other for longer periods and more often as the pregnancies went on. Researchers were able to conclude that the performance of movements between the co-twins were not accidental but specifically aimed. The social pre-wiring hypothesis was proven correct:The central advance of this study is the demonstration that 'social actions' are already performed in the second trimester of gestation. Starting from the 14th week of gestation twin fetuses plan and execute movements specifically aimed at the co-twin. These findings force us to predate the emergence of social behaviour: when the context enables it, as in the case of twin fetuses, other-directed actions are not only possible but predominant over self-directed actions. Computer science In artificial intelligence, tabula rasa refers to the development of autonomous agents with a mechanism to reason and plan toward their goal, but no "built-in" knowledge-base of their environment. Thus, they truly are a blank slate. In reality, autonomous agents possess an initial data-set or knowledge-base, but this cannot be immutable or it
