Final answer:
The statement that disintegration is the second stage of culture adaptation characterized by nervousness and insecurity is false. Culture shock indeed involves stress and disorientation, but 'disintegration' is not a recognized stage in the process of adapting to a new culture.
Step-by-step explanation:
The question about whether the second stage of culture adaptation is disintegration, with associated feelings of nervousness and insecurity, is actually false. While the concept of culture shock does include experiences of stress and disorientation, the stages of culture adaptation as defined by anthropologist Kalervo Oberg do not include a stage named 'disintegration.' The stages Oberg identified are: the honeymoon stage, culture shock, adjustment, and mastery. During the culture shock stage, individuals may indeed experience stress due to differences in language, etiquette, and other cultural norms, which can lead to feelings of incompetence and insecurity. These experiences are part of the stress adaptation process known as the general adaptation syndrome, which includes stages such as the alarm reaction, stage of resistance, and stage of exhaustion.
