1) Over the past 3-4 years, Rebecca has been going through numerous physical changes including a growth spurt and reaching sexual maturation. This is a normal developmental process occurring during adolescence, and is known as puberty. During puberty, an increase in growth hormone leads to a larger body size, characterized by the lengthening of the torso and weight gain. In average American girls, this growth spurt occurs around 10-11 years old; Rebecca was 10 when she went through her amazon minecraft lego. Gradually, Rebecca would begin to see more changes indicative of her sexual maturation, such as breasts, wider hips and accumulation of fat. Furthermore, there is an increase in brain activity within the frontal lobe, causing an increase in responsiveness to excitatory neurotransmitters. What this means, is that someone going through puberty often becomes more reactive to lego minecraft amazon. This may explain Rebecca’s thrill seeking behavior such as experimenting with drugs and it is also a factor in adolescent depression and eating disorders.
Rebecca’s parents have noticed a variable appetite. One cause may be her new concern with other people’s opinions. Recent physical changes may have lowered her self-esteem, as she now feels awkward and strange in her new body. She may be dealing with the social pressure to be thin and is therefore not eating regularly. This first began when she was 12 and took to staring at herself in the mirror, thinking, “I’m too fat.” On the other hand, perhaps Rebecca is unhappy because her new female physique is separating her from her male friends. Rebecca has been described as somewhat of a tomboy and maybe she is having difficulty with newly discovered gender identities and gender roles.
Finally, Rebecca’s physical changes may be causing mood swings. Her high points are likely around friends, whereas low points tend to be during adult-structured activities where she has less control. Rebecca may be feeling like school is no longer as enjoyable as it once was, and in an attempt to challenge authority, has decided she does not want to go to college. This could also be a plea for attention from her parents. Overall, it seems that the physical and psychological effects of puberty are taking a toll on Rebecca’s emotional well-being and social stability.
2) According to Piaget, the main cognitive change Rebecca will have gone through recently is her transition to the formal operations stage. This stage is normally reached by age 12 but it may take some children longer. The key difference between formal operations and concrete operations is that the adolescent is now able to think abstractly and deductively: They can consider future possibilities, test hypotheses, and draw conclusions about events they have not experienced firsthand. They do this in two ways.
The first is called ‘hypothetic-deductive reasoning’. Adolescents solve problems by considering all the possibilities and then proceed by eliminating those that could not occur in the real world. The second way has to do with the ‘propositional’ nature of the stage. Adolescents can focus on verbal assertions and evaluate their validity without making reference to real-world circumstances. So, the main change is that adolescents no longer need concrete evidence to make decisions.
Rebecca is clearly in the formal operational stage. For the past few years her parents have noticed her ability to grasp abstract concepts. For example, at 14, she was pointing out how aspects of her personality were similar to one parent or the other. Furthermore, she is gifted in math, with a particularly interest in science, which suggests she has a knack for understanding abstract ideas.
