In the present study, we investigated long-term effects of self-disclosure on social support in face-to-face and instant messenger (IM) communication between mutual friends. Using a representative sample of 583 German IM users, we explored whether self-disclosure and positive experiences with regard to social support would dynamically interact in the form of a reinforcing spiral across three measurement occasions. If mutual friends self-disclose today, will they receive more social support 6 months later? In turn, will this affect their willingness to self-disclose another 6 months later? We further analyzed spill-over effects from face-to-face to IM communication and vice versa. We found that self-disclosure predicted social support and vice versa in IM communication, but not in face-to-face communication. In light of these results, the impact of IM communication on how individuals maneuver friendships through the interplay between self-disclosure and social support are discussed.  相似文献

We summarize the results of four recent translational studies from our lab that used the predictions of behavioral momentum theory to inform the development of more durable treatments for destructive behavior. Treatments informed by behavioral momentum theory generally showed better suppression of target responding during an extinction challenge than did a comparison treatment. We reanalyze data from each of the four studies to show that this general finding is apparent both at the aggregate (i.e., proportion of baseline response rates averaged across participants) and within participant (i.e., percentage reduction in proportion of baseline response rates, difference in raw response rates during the extinction challenge). Interestingly, participants who experienced multiple cycles of the extinction challenge generally showed less differentiation in target responding between the treatment informed by behavioral momentum theory and the comparison treatment. Overall results suggest that applications of behavioral momentum theory can substantially improve the durability of common treatments for destructive behavior.  相似文献

Spontaneous recovery occurs when a previously reinforced and recently extinguished response reemerges over the course of time, often at the beginning of a new session of extinction. Spontaneous recovery could underlie instances of treatment relapse that threaten otherwise effective behavioral interventions for problem behavior. In two experiments, we arranged multiple schedules with pigeons and a human child to assess the effects of different training reinforcer rates on spontaneous recovery. In both experiments, responding was both more resistant to extinction and more likely to relapse following training with greater reinforcement rates upon returning to extinction after time off from extinction testing. A quantitative model based on behavioral momentum theory accounted well for the data, which suggests reexposure to the extinction context following time off during extinction resulted in (1) the failure of extinction learning to generalize, and (2) greater generalization of original learning during training. The present model attempts to quantify theories attributing spontaneous recovery to changes in temporal context.  相似文献

In two experiments, experimentally naïve rats were trained in concurrent variable‐interval schedules in which the reinforcer ratios changed daily according to a pseudorandom binary sequence. In Experiment 1, relative response rates showed clear sensitivity to current‐session reinforcer ratios, but not to previous sessions' reinforcer ratios. Within sessions, sensitivity to the current session's reinforcement rates increased steadily, and by session end, response ratios approached matching to the current‐session reinforcer ratios. Across sessions, sensitivity to the current session's reinforcer ratio decreased with continued exposure to the pseudorandom binary sequence, contrary to expectations based on previous studies demonstrating learning sets. Using a second group of naïve rats, Experiment 2 replicated the main results from Experiment 1 and showed that although there were increases over sessions in both changeover rate and response rate during the changeover delay, neither could explain the accompanying reductions in sensitivity. We consider the role of reinforcement history, showing that our results can be simulated using two separate representations, one local and one nonlocal, but a more complex approach will be needed to bring together these results and other history effects such as learning sets and spontaneous recovery.  相似文献

This study examines the individual and contextual factors associated with sociopolitical control expressed by immigrants in southern Spain. We used hierarchical linear modeling to evaluate the relations between individual (community participation, social connectedness, and perceived cultural competence of receiving community services) and municipality characteristics (city community participation, city social connectedness, and city community services’ cultural competence) and immigrants’ feelings of sociopolitical control. Data were analyzed using a two‐level model based on 707 Moroccan immigrants in 25 municipalities. After adjusting for gender, educational level, and psychosocial confounding factors, we observed a positive association between social connectedness and sociopolitical control at the individual level. At the contextual level, we observed a positive association between (a) city community participation, (b) city social connectedness, and (c) city community services’ cultural competence, and sociopolitical control. Indeed, living in a municipality where there are community services with high levels of cultural competence and where, on average, many people participate in organizations and neighbors are connected, was associated with higher levels of perceived control in the sociopolitical domain for immigrants. We also discuss implications for community‐based research and practice.  相似文献

We examined the extent to which different sounds functioned as motivating operations (MO) that evoked problem behavior during a functional analysis for two participants. Results suggested that escape from loud noises reinforced the problem behavior for one participant and escape from arguing reinforced problem behavior for the other participant. Noncontingent delivery of preferred music through sound‐attenuating headphones decreased problem behavior without the use of extinction for both participants. We discuss the results in terms of the abolishing effects of the intervention.  相似文献

According to a social rank hypothesis, consumers who live in regions with higher income inequality will show greater interest in, and attention toward, positional goods and high‐status brands that serve a social signaling role. We analyze millions of posts on the microblogging platform Twitter for mentions of high‐ and low‐status brands. We find that luxury brands such as “Louis Vuitton” and “Rolex” are more frequently mentioned in tweets originating from US states, counties, and major metropolitan areas with higher levels of income inequality. In contrast, mentions of everyday brands such as “Walmart” or “Kmart” are more frequent in regions with a more equal distribution of income. Using sentiment analysis, we find higher valence (positivity) and arousal (excitement) for tweets that both mention high‐status brands and originate from regions with high levels of income inequality. These results corroborate the social rank hypothesis, showing that more psychological resources are allocated to positional consumption when the income gap between the rich and the poor is larger.  相似文献

The body is as a living entity with three interrelated aspects: the physical motor skills, development processes, social and emotional interaction. The young child, regardless of his mental or physical condition, appropriates this entity when he is in contact with the surrounding world. Thus, the self-image will depend, in large part, on the person he is, the situation in which he lives (society, family), the nature and frequency of surrounding stimuli. A child carrying a handicap is likely to have a poor representation of his own self-image (disproportionate or deformed body) and an altered self-image, as far as he lives in a rejecting environment. In this paper, we have focused our research on how deaf children sees their self-image, based on our nineteen years of experience as a psychologist with hearing impaired children, in special schools. The various observations and assessments in this research, in addition to groups support offered to parents during all these years, give us today enough elements to show what kind of self-image the deaf child has of himself. Our assessment material was essentially thematic projective test of socialization –TSEA– and the drawing of the person.  相似文献

Children as pedestrians are one of the most vulnerable groups of road users. Therefore factors associated with risky pedestrian behaviour should be carefully studied. The aim of this article is to clarify how the traffic behaviour of 6th grade students as pedestrians is associated with the behaviour of their traffic companions and prevention activities at school, also taking gender into consideration. The research was conducted based on a randomly-selected sample of 1033 6th-grade students with the mean age of 12.77 ± 0.38 (SD) years. The results showed that compared to girls boys take significantly more risks as pedestrians: they rarely use reflectors during periods of darkness and often cross the road against the red light. The most important role models for adolescents in traffic behaviour are their parents. The role model behaviour with the strongest effect on adolescent high-risk behaviour in traffic is the role model not using crosswalks to cross the street. The results also showed that higher-risk traffic behaviour by adolescent pedestrians is predicted by higher-risk behaviour on the part of their companions (parents, teachers), walking alone on the street, as well as by an adolescent’s lower involvement in the less active prevention activities in the classroom. To improve adolescent pedestrians’ traffic behaviour social environment and school-based factors should be considered more thoroughly in prevention work at school.  相似文献
