Using a nationwide sample of 2656 eighteen- to twenty-nine-year-olds, the first part of the present study addressed the question of how non-traditional as compared to traditional living arrangements related to young people’s self-perception of being either adolescent or adult. Being in a romantic relationship increased the likelihood of feeling adult. Modern adult living arrangements (living alone in a single household or sharing an apartment with peers) increased the likelihood of feeling adolescent. Employing a longitudinal sample of 461 twenty- to twenty-seven-year-olds, changes in job status and sources of income were studied with regard to their connections to the emergence of subjective adulthood or the regression to subjective adolescence, respectively. No association between adult or adolescent self-perception and issues of work and material autonomy was found, but the emergence of subjective adulthood was related to romantic relationships and parenthood. Findings are discussed with reference to young people’s volatile living conditions and transient commitments implied by social change.  相似文献

The present study investigated event-based prospective memory in five age groups of preschoolers (i.e., 2-, 3-, 4-, 5-, and 6-year-olds). Applying a laboratory-controlled prospective memory procedure, the data showed that event-based prospective memory performance improves across the preschool years, at least between 3 and 6 years of age. However, our findings do not confirm early speculations that 2-year-olds may have attained reliable skills to carry out future intentions on their own. By contrast, there were first signs of prospective memory abilities among the 3-year-olds. The present study also revealed that children as young as 3 years can use external memory aids in the form of cue-action reminders to improve their event-based prospective remembering. Finally, the findings suggest that parents or caregivers can adequately estimate their preschool children's prospective memory abilities, as revealed by applying a modified version of the Prospective and Retrospective Memory Questionnaire (PRMQ).  相似文献

Pain modulation during drives through cold and hot virtual environments.   总被引:1,自引:0,他引:1  
Evidence exists that virtual worlds reduce pain perception by providing distraction. However, there is no experimental study to show that the type of world used in virtual reality (VR) distraction influences pain perception. Therefore, we investigated whether pain triggered by heat or cold stimuli is modulated by "warm "or "cold " virtual environments and whether virtual worlds reduce pain perception more than does static picture presentation. We expected that cold worlds would reduce pain perception from heat stimuli, while warm environments would reduce pain perception from cold stimuli. Additionally, both virtual worlds should reduce pain perception in general. Heat and cold pain stimuli thresholds were assessed outside VR in 48 volunteers in a balanced crossover design. Participants completed three 4-minute assessment periods: virtual "walks " through (1) a winter and (2) an autumn landscape and static exposure to (3) a neutral landscape. During each period, five heat stimuli or three cold stimuli were delivered via a thermode on the participant's arm, and affective and sensory pain perceptions were rated. Then the thermode was changed to the other arm, and the procedure was repeated with the opposite pain stimuli (heat or cold). We found that both warm and cold virtual environments reduced pain intensity and unpleasantness for heat and cold pain stimuli when compared to the control condition. Since participants wore a head-mounted display (HMD) in both the control condition and VR, we concluded that the distracting value of virtual environments is not explained solely by excluding perception of the real world. Although VR reduced pain unpleasantness, we found no difference in efficacy between the types of virtual world used for each pain stimulus.  相似文献

Patients who feel not wanted to exist as persons in their own right require that pastoral counseling or psychoanalysis address their need to be wanted. Drawing on case material, it is argued that the pastoral counselor has a particular responsibility to address adequately patients’ need to have their existence affirmed. Connecting psychoanalytic theory and technique with spiritual exploration of the notion of creation, this paper calls attention in clinical practice to patients’ need to be wanted to exist.  相似文献

This article provides an overview of a novel ecological momentary assessment method called the electronically activated recorder or EAR. The EAR is a portable audio recorder that periodically records snippets of ambient sounds from participants' momentary environments. In tracking moment-to-moment ambient sounds, the EAR yields an acoustic log of a person's day as it naturally unfolds. As a naturalistic observation method, it provides an observer's account of daily life and is optimized for the assessment of audible aspects of participants' daily social environments and interactions. The article discusses the EAR method conceptually and methodologically and identifies three important ways in which it can enrich social health research. Specifically, it can help cross-validate research findings independent of self-reports, calibrate psychological measures against behavioral markers of real-world social functioning, and further our understanding of the role that people's mundane social interactions and language use play in coping and health.  相似文献

Two types of experiments investigate the visual on-line and off-line processing of German ver-verbs (e.g., verbittern 'to embitter'). In Experiments 1 and 2 (morphological priming), latency patterns revealed the existence of facilitation effects for the morphological conditions (BITTER-VERBITTERN and BITTERN-VERBITTERN) as compared to the neutral conditions (SAUBER-VERBITTERN and SAUBERN-VERBITTERN). In Experiments 3 and 4 (rating tasks) participants had to judge whether the target (VERBITTERN) "comes from," "contains a form of," or "contains the meaning of" the root (BITTER) or the root+en substring (BITTERN). Taken together, these studies revealed the combined influence of the three factors of lexicality (real word status), morphological structure, and semantic transparency.  相似文献

The realization of delayed intentions (i.e., prospective memory) is a highly complex process composed of four phases: intention formation, retention, re-instantiation, and execution. The aim of this study was to investigate if executive functioning impairments are related to problems in the formation, re-instantiation, and execution of a delayed complex intention. In this context, it was another aim of the study to investigate the executive functioning hypothesis of cognitive aging in prospective memory performance. It was, therefore, explored if age-related prospective memory decline leads to similar decrements in the process of prospective remembering as executive functioning-related decline in young patients with traumatic brain injury. A group of patients with traumatic brain injury with retrospective memory within normal limits but impaired executive functions, a group of healthy older and a group of healthy younger adults completed a complex prospective memory task that allows for the separate assessment of the four phases of the prospective memory process. All groups showed a similarly high performance in the intention retention phase, whereas the patients with deficits in executive functioning and the older participants performed worse than the healthy young participants in the intention formation, re-instantiation and execution phases. The importance of executive functioning for prospective remembering in traumatic brain injury and normal aging is discussed.  相似文献

In the present study, the authors explored age differences in event-based prospective memory (PM) across adolescence. The tasks consisted of an ongoing task (OT; i.e., personality questionnaire items, math problems) and an embedded prospective task that required participants to remember to make a special response whenever they encountered a PM cue (i.e., a negative word in the OT). The 341 participants (aged 13-22 years) revealed a significant main effect of age, which indicated better PM performance of young adults compared with teenagers. Moreover, when emphasizing the OT versus the PM task, teenagers' PM profited from PM emphasis more than did young adults' PM. The authors discuss the data in the context of limited executive capacity as a factor influencing cognitive development across adolescence.  相似文献
