Many adolescents have hopes of college graduation, independent living, and satisfying careers. Career preparation is an important component that can facilitate these desires. However, many adolescents do not achieve these hopes in their desired timeframes due to interruptions, such as unplanned pregnancies. As illustrated by the Theory of Adolescent Sexual Decision-Making Influencing Teen Pregnancy (Weiss, 2012. Who will listen? Rural teen pregnancy reflections. The Journal for Nurse Practitioners, 8, 804–809. doi:10.1016/j.nurpra.2012.02.028), desiring future success can promote low-risk decision-making. Based on this theory, a Getting Plans Started (GPS) Timeline Tool (GPS Timeline©) was developed to help adolescents plan for future success by using a time perspective and, thereby, avoid interruptions. The purpose of this paper is to describe the GPS Tool©, how it might be used, and a study to determine the feasibility of using the GPS Tool©. Thirty adolescents found the tool easy to use and effective in helping them plan for the future. Their responses indicated almost unanimous desires for college graduation and independence with strong confidence in achieving their plans, but their responses also indicated a need for more effective planning to achieve their desired goals.  相似文献

When attempting to detect a near-threshold signal, participants often incorrectly report the presence of a signal, particularly when a stimulus in a different modality is presented. Here we investigated the effect of prior experience of bimodal visuotactile stimuli on the rate of falsely reported touches in the presence of a light. In Experiment 1, participants made more false alarms in light-present than light-absent trials, despite having no experience of the experimental visuotactile pairing. This suggests that light-evoked false alarms are a consequence of an existing association, rather than one learned during the experiment. In Experiment 2, we sought to manipulate the strength of the association through prior training, using supra-threshold tactile stimuli that were given a high or low association with the light. Both groups still exhibited an increased number of false alarms during light-present trials, however, the low association group made significantly fewer false alarms across conditions, and there was no corresponding group difference in the number of tactile stimuli correctly identified. Thus, while training did not affect the boosting of the tactile signal by the visual stimulus, the low association training affected perceptual decision-making more generally, leading to a lower number of illusory touch reports, independent of the light.  相似文献

The effect of test-induced priming on false recognition was investigated in children aged 5, 7, 9, and 11 years using lists of semantic associates, category exemplars, and phonological associates. In line with effects previously observed in adults, nine- and eleven-year-olds showed increased levels of false recognition when critical lures were preceded by four studied items. This pattern was present with all three list types. In contrast, no effects of test-induced priming were observed in five- or seven-year-olds with any list type. The results also support those of previous studies in showing a developmental shift from phonological to semantic false memories. The findings are discussed in terms of current theories of children's false memories.  相似文献

Mental simulations of future experiences are often concerned with emotionally arousing events. Although it is widely believed that mental simulations enhance future behavior, virtually nothing is known about how memory for these simulations changes over time or whether simulations of emotional experiences are especially well remembered. We used a novel paradigm that combined recently developed methods for generating simulations of future events and well-established procedures for testing memory to examine the retention of positive, negative, and neutral simulations over delays of 10 min and 1 day. We found that at the longer delay, details associated with negative simulations were more difficult to remember than details associated with positive or neutral simulations. We suggest that these effects reflect the influence of the fading-affect bias, whereby negative reactions fade more quickly than positive reactions, and that this influence results in a tendency to remember a rosy simulated future. We discuss implications of our findings for individuals with affective disorders, such as depression and anxiety.  相似文献

Objective: To examine the feasibility, safety, and acceptability of a manualized protocol of occupational therapy using sensory integration principles for children with autism. Methods: Ten children diagnosed with autism spectrum disorder ages 4-8 years received intensive occupational therapy intervention using sensory integration principles following a manualized protocol. Measures of feasibility, acceptability and safety were collected from parents and interveners, and fidelity was measured using a valid and reliable fidelity instrument. Results: The intervention is safe and feasible to implement, acceptable to parents and therapist, and therapists were able to implement protocol with adequate fidelity. These data provide support for implementation of a randomized control trial of this intervention and identify specific procedural enhancements to improve study implementation.  相似文献

Happiness is a positive phenomenon that is universal in nature and is therefore, pertinent to all human beings. However, the definition of happiness differs from person to person, and varies among cultures, economic status, social connectedness, spiritual upbringing and daily situations. An individual’s contextual perception of happiness can change when subjected to bleak conditions such as incarceration wherein inmates, especially those who are old and are experiencing health impairments are stripped off with their customary source of happiness. Since Filipinos are known to be as “happy people,” this study purports to surface the different facets of what constitute happiness in the context of a penal institution in the Philippine setting. The Q-methodology is the primary design used in the study. It combines the objectivity of quantitative approach with the essence of human experiences as explored in qualitative studies. The participants (P-sample) were twenty elderly inmates suffering from chronic ailments. They were asked to arrange 32 statements (Q-sample), derived from the initial interview, in the Q-sort table based on their degree of agreement, which were then further explicated in the post-sort interviews. The results were then subjected to by-person factor analysis with varimax rotation using the PQ Method version 2.11. Five profiles emerged from the by-person factor analysis, namely: (1) ‘Sense of Affinity’, (2) ‘Sense of Opportunity’, (3) ‘Sense of Indemnity’, (4) ‘Sense of Positivity’ and (5) ‘Sense of Resiliency’. The discussion focused on similarities and differences among profiles regarding the four principal themes (familial, social, internal and spiritual components of happiness) derived from the statements used as the Q-sample. The perception of happiness varies from profile to profile. The differences in views on what constitutes happiness among profiles are more prominent than their said similarities. Most leanings are directed toward the familial and spiritual aspects of happiness however, happiness can also be internally motivated and cognitively construed. While happiness has a direct relationship to an individual’s overall perception of well-being, the nurse, being the primary provider of holistic care, plays a pivotal role in promoting optimum health through awareness, knowledge, and appreciation of vis-a vis an unwavering involvement with the unique and distinct psychological and emotional needs of the elderly inmates characterized by respect, openness, authenticity and inter-subjectivity.  相似文献

This paper is the first phase of a longitudinal study of the class of 2014 on the effectiveness of ethics education at a business university. This phase of the project establishes the baseline attributes of incoming college freshmen with a pretest of the students’ ethical proclivity as measured by Defining Issues Test (DIT-2) scores. The relationship between the students’ ethical reasoning and their behavior in experimental stock trading sessions is then examined. In the trading simulations, randomly selected students were provided with the option of receiving privileged insider information about the final payoff of several stocks. The students could either accept or reject such information, with acceptance considered illegal insider trading. The results of the pretest indicate that moral reasoning as measured by the DIT-2 is related to insider trading behavior, with students with higher DIT-2 scores being less likely to accept insider information. The paper also presents demographic differences across DIT-2 scores and trading behavior as a foundation for the longitudinal examination of changes in students’ moral cognition characteristics and behavior during their undergraduate career.  相似文献

The performance of 14 soldiers was evaluated during 3 hr of simulated sentry duty when (a) the primary work rate was varied and (b) participants were required to intermittently perform a simple secondary task. Performance measurements included latency to detect a target, number of correct target detections, correct friend versus foe identification, targets hit, and latency to respond to the presentation of a continuous tone (secondary task). Activity monitors measured motor activity during study participation. During higher work rate sessions, participants responded to the appearance of a target more quickly, discriminated friend from foe more accurately, and hit more foe targets. The addition of a simple auditory task to the primary task did not affect performance on any of the sentry duty measures. These findings demonstrated that moderate increases in task engagement, or work rate, improved most performance metrics on a long duration (3-hr), militarily relevant vigilance task.  相似文献

Investigated were relations among executive cognitive function (ECF), food intake, and physical activity in 184, fourth grade children. It was hypothesized that self-reported ECF proficiency would predict greater self-reported fruit/vegetable intake and physical activity, but less “snack food” intake. Structural models demonstrated that ECF was significantly correlated with less concurrent snack food intake and greater concurrent fruit/vegetable intake, but not physical activity. Baseline ECF also significantly predicted greater fruit/vegetable intake and physical activity four months later, but not snack food intake. One implication is to promote ECF as a correlate and predictor of food intake and physical activity in children by providing opportunities for youth to practice newly developing ECF capacities.  相似文献

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) was published in May 2013 and features (in Section III) a new model for the diagnosis of personality disorders. The aim of this paper is to introduce this model to a broader German-speaking readership. The article begins by explaining why a new model seems necessary. Secondly, the different components of the new DSM-5 model are presented, the theoretical and empirical background is explained and it is shown how the model works using a clinical case example. Thirdly, several advantages of the new model as compared to the DSM-IV diagnostic categories (which will be retained in DSM-5 Section II) are discussed. Finally, the article highlights some open questions and problems that require further conceptual and empirical research.  相似文献
