摘要：Whereas human beings are only seem to” have” cognitive processes they have the knowledge about the process itself as well. This process, which is known as metacognition should be taken as a system responsible for the proper functioning of whole memory system via its executive role in information processing. .Despite some differences on naming and defining the term metacognition in literature, researchers agreed on the fact that metacognition has two general aspects; monitoring and controlling. When taken from a developmental perspective an increment takes start in information processing capacity and functionality of cognitive functions directly related with executive functions including non-verbal reasoning, decision making, problem solving, abstracting, using the acquired information and producing new information of adolescents by the age 11 which is the onset of the formal operational stage. Thus level of metacognitive development might be an indicator and predictor of the general developmental status of executive functions such as decision making in adolescents. A total of 150 adolescents (75 female and 75 male) attended different schools in European and Anatolian sides of Istanbul participated in this study in which relation among metacognitive functions, decision making and locus of control was inquired. Another goal of this study was take the relation among metacognitive function and some socio-demographic features such as age, sex, educational status of the parents and family structure under investigation. Results underpin that the level of metacognitive functionality as a prominent predictor of decision making and locus of control in first years of adolescence period
