This paper reviews several psychosocial theories that have been applied to the study of adolescent health behavior. Some of these theories have existed for several decades and, though not originally intended for this purpose, have proven quite useful in predicting and explaining many different types of health‐relevant behaviors. During the last 10–15 years, however, there has been a significant increase in the application of social psychological theories to the examination of what is increasingly being seen as a social‐psychological phenomenon: health risk behavior among adolescents. This interest has been prompted, in part, by an appreciation of the value of dual‐processing principles in explaining these behaviors, and, in particular, a recognition that much adolescent health risk behavior: a) is not always planful or premeditated, and b) involves both heuristic and analytic processing. The paper includes discussion of how dual‐processing principles and social‐psychological theories can inform intervention efforts. 相似文献

We used event-related brain potentials (ERPs) to investigate the various mental processes contributing to evaluative priming—that is, more positive judgments for targets preceded by affectively positive, as opposed to negative, prime stimuli. To ensure ecological validity, we employed a priori meaningful landscape pictures as targets and emotional adjectives as visual primes and presented both primes and targets for relatively long durations (>1 s). Prime-related lateralized readiness potentials (LRPs) revealed response priming as one source of the significant evaluative priming effect. On the other hand, greater right-frontal positive slow wave in the ERP for pictures following negative, as compared with positive, primes indicated altered impression formation, thus supporting automatic spreading activation and/or affect misattribution accounts. Moreover, target LRPs suggested conscious counter-control to reduce the evaluative priming net effect. Finally, when comparing prime ERPs for two groups of participants showing strong versus weak evaluative priming, we found strong evidence for the role of depth of prime processing: In the weak-effect group, prime words evoked an increased visual P1/N1 complex, a larger posterior P2 component, and a greater left-parietal processing negativity presumably reflecting semantic processing. By contrast, a larger medial-frontal P2/N2 complex in the strong-effect group suggested top-down inhibition of the prime’s emotional content. Thus, trying to ignore the primes can actually increase, rather than decrease, the evaluative priming effect. 相似文献

Usually, a probe target appearing in a recently ignored distractor location is less efficiently processed. This robust phenomenon is called (visuo-) spatial negative priming (SNP). Among other explanations, concepts of persisting or retrieved spatial inhibition play a major role. Two relevant issues were investigated using event-related brain potentials (ERPs). The first pertains to context sensitivity of inhibition: Is a probe distractor necessary for SNP? The second concerns levels of processing at which spatial inhibition operates: Does SNP affect perception, selection, and/or stimulus classification? A localization task with and without probe distractors was employed while 64-channel EEG was recorded. Obviously, SNP does not require a probe distractor; the distractor-absent SNP effect was larger than the distractor-present SNP effect. Distractor-present SNP had two lateralized ERP effects, N1pc amplitude reduction and N2pc amplitude increase. Smaller N1pc may indeed reflect perceptual decrement, but was inversely related to size of behavioral SNP. By contrast, only strong-SNP participants showed N2pc increase, which points to selection disadvantage due to persisting inhibition of higher-level spatial representations. Distractor-absent SNP had no N1pc/N2pc correlates; instead, reduced amplitude of a broadly distributed P300 component suggests impaired stimulus classification due to episodic retrieval of inappropriate prime information. Overall, SNP seems to emerge from relatively late stages of processing, thus challenging the idea of context-free persisting inhibition of low-level spatial representations. Furthermore, distractor-present and distractor-absent SNP are qualitatively different from each other. 相似文献

Participants in two studies recalled autobiographical events and reported both the affect experienced at event occurrence and the affect associated with event recollection. The intensity of affect associated with a recalled event generally decreased, but the affective fading was greater for negative events than for positive events. The magnitude of this fading affect bias also varied with participants' dysphoria levels: Dysphorics showed a smaller fading affect bias than non-dysphorics. Additional analyses suggested that the fading affect bias is not a product of: (1) distorted retrospective memory for the affect originally accompanying events; (2) differences in the initial affect intensity of positive and negative events; or (3) differences in the ages of positive and negative events. Other variables that might be related to the fading affect bias are discussed. 相似文献

Two experiments were conducted to examine the effect of the mental retardation (MR) label on impression formation among retarded and nonretarded children and adolescents. The first experiment, conducted with nonretarded children in a mainstreamed school, indicated that they have pessimistic expectations of retarded children with regard to cognitive and ability-related behaviorsand, to a lesser extent, social behaviors (i.e., getting married). However, their reactions were not as pessimistic nor as “patronizing” as were those demonstrated by college students in previous research. In the second experiment, mentally retarded adolescents indicated that they also have negative behavioral expectations of retarded children, however, their self expectations were negative only for social behaviors. The results suggest that, among retarded persons, the expectations associated with the MR label are negative for social behavior, but apparently less pessimistic for cognitive and ability related tasks. 相似文献

This prospective study examined the relation between 308 adolescents' images of typical dinkers and nondrinkers and their subsequent alcohol consumption. The results indicate that both images are associated with changes in consumption between ages 16 and 18 but that they operate in different ways. Contrary to previous assumptions, drinker images do not represent goal states for adolescents in that they are more negative than their self-images and nondrinker images and are not correlated with their ideal selves. In contrast, nondrinker images do appear to represent goal states for adolescents who abstain from drinking. Implications for intervention are discussed. 相似文献

Two appearance-based interventions designed to increase sun protection intentions and behaviors were evaluated. Sixty-eight college students in Experiment 1 and 76 beachgoers in Experiment 2 were randomly assigned to receive or not receive a photoaging (premature wrinkling and age spots) information intervention and, separately, to receive or not receive a novel ultraviolet (UV) photo intervention that makes the negative-appearance consequences of UV exposure more salient. Both experiments indicated that the UV photo intervention significantly increased intentions to use sunscreen in the future. A follow-up conducted with the beach sample indicated that UV photo information also produced greater protective behaviors for incidental sun exposure and that the combination of UV photo and photoaging information resulted in substantially lower reported sunbathing. 相似文献

Anxiety symptoms are fairly common among patients with Alzheimer's Disease (AD). Such symptoms are likely to make patient care more problematic and, therefore, increase the risk of nursing home placement. Anxiety symptoms were evaluated on the basis of physician examinations, in conjunction with caregiver interviews, in 372 community-dwelling AD patients. Patients received annual follow-up for 1–12 years (M = 4.4). Patients who exhibited anxiety symptoms at baseline assessment were significantly more likely to enter nursing homes, regardless of initial cognitive status or other risks for institutionalization. There was a 15% increase in risk for each point on a 0–5 scale. This study supports the hypothesis that anxiety symptoms increase the risk of nursing home placement in patients with AD. Consequently, there is a need for better understanding of the causes of anxiety in AD and for the development of effective methods of assessment and treatment. 相似文献
