When eye and hand movements are concurrently aimed at double-step targets that call for equal and opposite changes of response direction (–10° for the eyes, +10° for the hand), adaptive recalibration of both motor systems is strongly attenuated; instead, hand but not eye movements are changed by corrective strategies (V. Grigorova et al., 2013a). The authors introduce a complementary paradigm, where double-step targets call for a –10° change of eye and a ?30° change for hand movements. If compared to control subjects adapting only the eyes or only the hand, adaptive improvements were comparable for the eyes but were twice as large for the hand; in contrast, eye and hand aftereffects were comparable to those in control subjects. The authors concluded that concurrent exposure of eyes and hand to steps of the same direction but different size facilitated hand strategies, but didn't affect recalibration. This finding together with previous one (V. Grigorova et al., 2013a), suggests that concurrent adaptation of eyes and hand reveals different mechanisms of recalibration for step sign and step size, which are shared by reactive saccades and hand movements. However, hand mostly benefits from strategies provoked by the difference in target step sign and size. 相似文献

This study is aimed to validate the Italian version of the dependency-oriented and achievement-oriented psychological control scale (DAPCS), a self-report questionnaire designed to assess the adolescent’s perception of the two dimensions of psychological control. In Study 1, we assessed factorial validity and reliability of the Italian version of DAPCS with a sample of adolescents. In Study 2, we examined the convergent validity of the Italian version of the DAPCS analyzing the associations between the two domains of psychological control and well-established measures related to them such as strictness/supervision, overprotection, non dependency on parents, and family functioning. Confirmatory factor analyses confirmed the hypothesized two-factor solution of the DAPCS, with a 16 items’ version better fitting the data, for paternal as well as for maternal ratings. High indices of internal consistency indicated that both subscales produced reliable scores. Convergent validity was confirmed by positive associations between the DAPCS’ subscales and measures of strictness and negative associations between the DAPCS’ subscales and measures of global family functioning, both for maternal and paternal ratings. Finally, results evidenced significant effects for adolescents’ and parental gender on achievement-oriented psychological control, with mothers rated higher than fathers by males and fathers rated higher than mothers by females. Overall, the results of these studies indicated that the Italian form of the DAPCS might be a useful instrument to assess the two domain-specific types of parental psychological control among Italian-speaking adolescents. 相似文献

Using data from the Birth to Three Phase (1996–2001) of the Early Head Start Research and Evaluation Project, we investigated whether family routines at 14, 24, and 36 months play a role in the development of children's self-regulation and cognitive ability at 36 months. The moderating effects of child sex and race/ethnicity were also examined. Analyses revealed that routines do matter for child outcomes; concurrent routines appear to be critical for fostering self-regulation at 36 months, whereas early routines may be important for children's later cognitive ability. Second, the effects differed by child sex, with early routines having a stronger association for girls and concurrent routines having a stronger association for boys. Associations also varied by race/ethnicity such that routines appear to matter slightly more for African–American children than European–American and Hispanic children. Implications of these findings with respect to strength-based interventions for low-income preschoolers and their families are discussed. 相似文献

Arts, Real-Time Video and Interactivity for Sustainability (ARTiVIS) is an ongoing collaborative research project investigating how real-time video, DIY surveillance technologies and sensor data can be used as a tool for environmental awareness, activism and artistic explorations. The project consists of a series of digital contexts for aesthetic contemplation of nature and civic engagement, aiming to foster awareness and empowerment of local populations through DIY surveillance. At the core of the ARTIVIS efforts are a series of interactive installations (namely B-Wind!, Hug@tree and Play with Fire), that make use of surveillance technologies and real-time video as raw material to promote environmental awareness through the emotion generated by real-time connections with nature. Throughout the project development, the surveillance concept has been shifting from the use of surveillance technology in a centralized platform, to the idea of veillance with distributed peer-to-peer networks that can be used for science and environmental monitoring. In this paper we present the history of the ARTiVIS project, related and inspiring work, describe ongoing research work and explore the present and future challenges of appropriating surveillance technology for artistic, educational and civic engagement purposes. 相似文献

The ability to imagine future events (episodic future thinking—EFT) emerges in preschoolers and further improves during middle childhood and adolescence. In the present study, we focused on the possible cognitive factors that affect EFT and its development. We assessed the ability to mentally project forward in time of a large cohort of 135 6- to 11-year-old children through a task with minimal narrative demands (the Picture Book Trip task adapted from Atance and Meltzoff in Cogn Dev 20(3):341–361. doi:10.1016/j.cogdev.2005.05.001, 2005) in order to avoid potential linguistic effects on children’s performance. The results showed that this task can be used to assess the development of EFT at least until the age of 8. Furthermore, EFT scores correlated with measures of phonological short-term and verbal working memory. These results support the possibility that cognitive factors such as working memory play a key role in EFT. 相似文献

Cannabinoid receptor 1 gene (CNR1) variants have been related to affective information processing and, in particular, to stress release. Here, we aimed to examine whether the endocannabinoid system via CNR1 signaling modulates affective working memory, the memory system that transiently maintains and manipulates emotionally charged material. We focused on rs2180619 (A?>?G) polymorphism and examined genotype data collected from 231 healthy females. Analyses showed how a general positivity bias in working memory (i.e., better memory for positive words) emerged as task strings lengthened only in carriers of the major allele (AA/AG). Differently, GG carriers showed better memory for affective items in general (i.e., positive and negative words). These findings are some of the first to directly highlight the role of variant on promoter of the CNR1 gene in affective working memory and to evidence a differentiation among CNR1 genotypes in terms of larger difficulties in disengaging from negative stimuli in GG carriers. 相似文献

A meta-analysis summarizing results of 187 studies reporting cross-sectional and longitudinal relationships between job satisfaction and personality is described. The Big Five factor of Neuroticism related most strongly and negatively to job satisfaction (?.25), with the other factors ranging from .16 (Conscientiousness) to ?.02 (Openness to Experience). Job satisfaction was positively related to internal locus of control (LOC), positive affectivity, and Type A (achievement striving). Results showed negative relationships with external LOC, trait anger, Machiavellianism, negative affectivity/trait anxiety, and Type A (global and impatience/irritability). Job satisfaction had a very weak, negative correlation with narcissism that was indistinguishable from zero. These relationships were similar, although the effect sizes were generally not as strong, when examined in a longitudinal context. The distinctiveness of Extraversion and positive affectivity, as well as that of global and composite measures of job satisfaction, are discussed. 相似文献

The authors propose a reflection on a time-limited psychoanalytic group for children, adolescents and families, run in a public service. Some patients in the group give accounts of violent relationships and traumatic experiences. The accounts of violent, interpersonal and intrapsychic relationships influence the group’s capacity of thinking, which leads to difficulties in the processing of symbolic aspects. The fundamental question is that of whether it is possible to work in a time-limited, institutional, psychoanalytical framework, in which psychotherapists have to attempt to give meaning to experiences which take place in a repetitive present, in a space/time in which the prospect of a conclusion appears to be inconceivable. By means of a clinical example, and with particular emphasis on the first sessions and the dream brought up by a patient who has been a victim of domestic violence, the authors discuss the possibility of modifying, chiefly from within, the feeling of the immutability of early psychic material, which is itself intrinsically violent. 相似文献

AbstractIn order to study the effects of mindfulness meditation interventions administered to adolescents within their educational institutions, a qualitative systematic review was conducted. Sixteen studies published in main databases were analysed. The results show that mindfulness, as a prevention strategy in educational contexts, resulted in significant changes in the followings variables: (a) psychological (e.g., reduction in depressive symptoms); (b) psychosocial (e.g., increased social skills); and (c) physiological (e.g., improvement of blood pressure). Although the results were conclusive, their interpretation and generalization should be carefully analysed as there were no medium- and long-term follow-up evaluations, in addition to the fact that there has been a minimal assessment of the psychological mechanisms involved in the change processes. 相似文献
