In the past, society has restricted the vocational opportunity of some of its members. This restriction has affected the individual's self-concepts and his mode of adaptation. The ex-public offender, due to societal limitations of vocational choice, may anticipate some difficulty in obtaining and licensing. Other problems, which handicap the person with a criminal record, are denoted and discussed.  相似文献

THE "FRESHMAN 15"Facts and Fantasies About Weight Gain in College Women   总被引:1,自引:0,他引:1  
This research tested the hypothesis that the "freshman 15" may be more fantasy than fact. The "freshman 15" refers to the belief that college students, particularly women, gain an average of 15 pounds during their first year of college. Female college students were weighed during their first month at college and again 6 months later. They also completed measures of self-esteem, body image, locus of control, and self-monitoring. Findings indicated that the majority of women remained the same weight during the first 6 months of college. A favorable body image was related to less weight loss among those who lost weight, but none of the other characteristics were related to weight change.  相似文献

The central nervous system of altricial infants is specialized for optimizing attachments to their caregiver. During the first postnatal days, infant rats show a sensitive period for learning and particularly susceptible to learning an attraction to their mother’s odor. Classical conditioning appears to underlie this learning that is expressed behaviorally as anincreased ability to acquire odor preferences and a decreased ability to acquire odor aversions. Specifically, in neonatal rats, pairing an odor with moderately painful shock (0.5mA) or milk produces a subsequent relativepreference for that odor. The neural circuitry supporting theincreased ability to acquire odor preferences appears to be the heightened functioning of the noradrenergic pontine nucleus locus coeruleus. Indeed, norepinephrine from the locus coeruleus appears to be both necessary and sufficient for learning during the sensitive period. On the other hand, thedecreased ability to acquire odor aversions seems to be due to the lack of participation of the amygdala in at least some aversive learning situations. The site of plasticity in the pup’s brain appears to be limited to the olfactory bulb. This neonatal sensitive period for learning ends around postnatal day 9–10, at which time pups make the transition from crawling to walking and classical conditioning becomes “adultlike”. The neonatal behavioral and neural induced changes are retained into adulthood where it modifies sexual behavior.  相似文献
