Reports an error in "Longitudinal Changes in Behavioral Approach System Sensitivity and Brain Structures Involved in Reward Processing During Adolescence" by Sne?ana Uro?evi?, Paul Collins, Ryan Muetzel, Kelvin Lim and Monica Luciana (Developmental Psychology, Advanced Online Publication, Mar 5, 2012, np). Figure 2 was distorted in production. The correct version is presented in the erratum. (The following abstract of the original article appeared in record 2012-05404-001.) Adolescence is a period of radical normative changes and increased risk for substance use, mood disorders, and physical injury. Researchers have proposed that increases in reward sensitivity (i.e., sensitivity of the behavioral approach system [BAS]) and/or increases in reactivity to all emotional stimuli (i.e., reward and threat sensitivities) lead to these phenomena. The present study is the first longitudinal investigation of changes in reward (i.e., BAS) sensitivity in 9- to 23-year-olds across a 2-year follow-up. Support was found for increased reward sensitivity from early to late adolescence, and evidence was found for decline in the early 20s. This decline is combined with a decrease in left nucleus accumbens (Nacc) volume, a key structure for reward processing, from the late teens into the early 20s. Furthermore, we found longitudinal increases in sensitivity to reward to be predicted by individual differences in the Nacc and medial orbitofrontal cortex (OFC) volumes at baseline in this developmental sample. Similarly, increases in sensitivity to threat (i.e., behavioral inhibition system sensitivity) were qualified by sex, with only females participants experiencing this increase, and predicted by individual differences in lateral OFC volumes at baseline.

The aim of this study was to explore the influence on Mexican citizens of several variables that have been reported as being important in the literature on fear of victimization. Sociodemographic variables such as gender, age group and socioeconomic level, together with perceived risk of victimization, perceived seriousness in the face of different acts, experienced victimizations and perception of control of violence and crime are included among these variables. One hundred and eighty-one people were interviewed in a cross-sectional field study. Multiple regression analyses were carried out in three fear of victimization dimensions: personal, property and general situations. On the whole, the findings confirm the influence of the aforesaid variables. Being a woman, feeling at risk of being the object of violent attacks and the seriousness with which moderately violent acts are perceived were some of the major variables considered to predict fear of victimization. 相似文献

Healthy adolescents, ages 9-23, completed delay and probability discounting tasks and measures of verbal and nonverbal intelligence, executive functioning, and self-reported internalizing and externalizing behavior. Delay but not probability discounting decreased with age. Delay discounting was also associated with verbal intelligence and Go-NoGo and Iowa Gambling Task performance. Probability discounting was associated only with externalizing behavior. Findings conform to an accumulation of evidence that while delay and probability discounting may have some overlapping components, they also reflect some fundamentally different processes in this age group. 相似文献

The purpose of this paper is to summarize the empirical findings related to the assessment and treatment of sexual difficulties commonly experienced by gynecological cancer survivors and to make suggestions for future research and practice in this area. First, we describe the sexual problems that are most frequently reported by gynecological cancer patients and some of their common medical and psychological correlates. These include pain, premature ovarian failure, changes in vaginal anatomy, emotional distress, body image, and sexual self-concept. The complex interaction of physiological and psychological variables plays an important role in the development of sexual dysfunction in this patient population. Furthermore, we review the empirical studies that have examined the effects of sexual rehabilitation therapy on the sexual functioning of gynecological cancer survivors and provide relevant research and clinical recommendations. We also discuss reasons to involve patients' sexual partners in psychosocial oncology research, given the complex interplay between patients' and partners' psychosexual issues. 相似文献

Healthy adolescents (79 girls, 66 boys), ages 9-17, completed the Iowa Gambling Task (IGT; A. Bechara, A. R. Damasio, H. Damasio, & S. W. Anderson, 1994) as well as working memory (digit span) and behavioral inhibition (go/no-go) tasks. Cross-sectional age-related changes were seen on all 3 tasks. Gender differences were seen in IGT deck preference and attentional variables (i.e., go/no-go hit rate and forward digit span). After age, gender, and general intellectual abilities were controlled for, IGT performance was not predicted by working memory or behavioral inhibition scores. Findings suggest that the ventromedial prefrontal cortex or its connections are functionally maturing during adolescence in a manner that can be distinguished from maturation of other prefrontal regions. Development of these functions may continue into young adulthood. 相似文献

Even though disposition is present in the consumer behavior research agenda, most of the studies focus mainly on intentional movements of products leaving the home. The present article describes a less conscious and co‐incidental journey of products into a liminal zone between use and disposal inside homes. A qualitative field study, based on the itinerary method, was undertaken with a group of 26 affluent women in Brazil. The findings show that consumers maintain purgatories – “forgotten” repositories of products no longer in use – as an in‐home disposition practice. The aspects and functioning of purgatory are also detailed, through a typology of purgatories and a discussion of specific strategies to deal with cluttering as a consequence of product accumulation inside homes. Finally, purgatories emerge as a contemporary consumer solution to deal not with individual products but with product collectivities' disposition. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献
