Subjective magnitude characteristics for vibrotaction were determined by the method of numerical magnitude balance for three body sites varying in the density of neural innervation: the distal pad of the middle finger, the thenar eminence, and the volar forearm. The effects of a rigid surround upon threshold and the rate of growth of subjective intensity were measured. The results support the suggestion that absolute threshold and the rate of growth of subjective intensity are inverse functions of the total number of sensory neural units stimulated rather than being related simply to the density of neural innervation.  相似文献

This essay challenges whether or not the use of district money for Reading Recovery© (RR) instruction is an effective expenditure of funds that results in sustained improvement in student reading outcomes. As a Tier 3 intervention, RR provides expensive, one-on-one tutoring for first- and second-grade readers that is occupying an increasingly larger instructional space across districts. While some studies have shown improvement due to RR, others show these results eventually dissolve. A disturbing trend is advocacy by some RR teachers that RR methods be incorporated into Tier 1 instruction. In this essay we further explore the issues surrounding RR.  相似文献

Decreased dysfunctional thinking in recovering depressed patents could reflect predominantly (a). reduced access to dysfunctional schemas or (b). increased metacognitive monitoring of dysfunctional schematic products. Twenty acutely depressed patients, 20 partially remitted depressed patients, and 20 controls were compared on tasks primarily reflecting one or the other of these processes. On both tasks, acutely depressed patients differed significantly from controls. Partially remitted patients resembled acutely depressed patients on the task assessing dysfunctional schema access but resembled controls on the metacognitive monitoring task. Results suggest that reduced dysfunctional thinking associated with partial remission is mediated primarily by increased metacognitive monitoring of dysfunctional cognitive products rather than reduced access to dysfunctional schemas.  相似文献

The present study examines whether the degree of congruence between the patient's and the partner's perceptions of myocardial infarction (MI) has an influence on a range of recovery outcomes in the patient. The MI perceptions of 70 Portuguese couples in which the male had suffered a first heart attack were assessed at 3 months after discharge from hospital, using the Illness Perception Questionnaire (IPQ). Several dimensions of patient recovery were assessed at 3, 6 and 12 months post-MI, using standardised measures of psychological well-being, return to work, disability, social functioning, sexual functioning, and indices of lifestyle changes. The degree of congruence in each couple's illness perceptions was assessed and related to each outcome measure. The results suggest that the degree of congruence between patients and partners in their illness perceptions was related to different dimensions of recovery at 3, 6 and 12 months. The results revealed that in couples who had similar positive perceptions of the identity and consequences of the MI, patients showed (a) better physical and psychological functioning, (b) better sexual functioning, and (c) less impact of MI on social and recreational activities. Also, similar positive perceptions of timeline were associated with lower levels of disability, and similar positive cure/control beliefs were linked with greater dietary changes. Separate analyses showed that these effects were not confounded with marital functioning. This study provides clear evidence that the degree of match/mismatch between the patient's and partner's perceptions of the MI is associated with a range of recovery outcomes.  相似文献

New learning often interferes with the production of older, previously learned responses. However, the original responses usually appear to spontaneously recover and regain their dominance after a delay. This article takes a new approach to questions of interference and recovery by examining performance on immediate and delayed tests using direct or indirect instructions. Direct instructions asked participants to deliberately retrieve the original responses, and indirect instructions allowed them to respond on a more automatic basis, using whatever response came to mind first. Results suggest that interference and recovery may have their largest effects via relatively automatic influences on memory, such as the accessibility of new versus original information. This finding adds a new perspective to classic theories of interference and recovery, and may also inform current understanding of performance in populations (e.g., older adults) that often rely predominantly on automatic memory processing.  相似文献

Adaptation of perceived movement during head motion (apparent concomitant motion, ACM) and the subsequent elimination of adaptation were studied in two experiments. During the adaptation phase of both experiments, subjects performed voluntary 1-Hz head oscillations for 6 min while fixating a stimulus moving either in the same (with) direction as or the opposite (against) direction of head movements. In Experiment 1, ACM adaptation was measured following either a 1- or a 4-min delay after the adaptation phase. Results indicated some loss of adaptation during the additional 3-min delay, demonstrating a tendency of the system linking head and image to return to its preadaptation state following removal of an adaptation stimulus. In Experiment 2, subjects viewed a stimulus after adaptation that appeared to move minimally in the same manner as the adaptation stimulus during 3 min of head oscillations. No loss of adaptation was measured in these subjects between the beginning and the end of the 3-min interval. In another condition, subjects viewed a stimulus that appeared to move alternately in the same direction as and in the opposite direction of the adaptation stimulus during a similar 3-min interval following adaptation. ACM adaptation was substantially reduced during this 3-min interval. These results implicate two mechanisms that operate to either maintain or eliminate ACM adaptation. One is passive and operates in the absence of visual feedback to eliminate the short-term adapted state, and the other responds to postadaptation visual feedback.  相似文献

The aim of this study was to assess the psychological state of women who have undergone surgery for breast cancer or cardiac surgery, including examination of the role of social support in both groups. The study included 48 women (mean age: 66.04?±?8.3 years). They were divided into two groups according to diagnosis: 23 women (mean age: 69.2?±?8.6 years) who underwent heart surgery (cardiac group, CG) and 25 women (mean age: 63.2?±?7.0 years) treated for breast cancer and associated with the Women After Mastectomy Club (oncology group, OG). In addition to the assessment of socio-demographic variables, the following self-report questionnaires were administered: Satisfaction with Life Scale, Acceptance of Illness Scale, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory as well as Berlin Social Support Scale. In the CG, the severity of depressive symptoms was two times higher than in OG (p?=?.003). In both groups, there was a high percentage (80%) of women with severe symptoms of anxiety (p?=?.37). In both groups, the level of life satisfaction was similar (p?=?.58), but OG was characterized by a higher level of acceptance of the disease (p?=?.003). The correlation analysis showed that in both groups, social support was related differently to the parameters of emotional state. Women treated for breast cancer were in a better mental condition than women treated for heart disease. The support coming from other women in similar circumstances (Women After Mastectomy Club) seems to be more effective than the support coming from the patient’s immediate environment. The results for social support ought to be interpreted not only through the prism of mean values of received support, but also with regard to the information on the sources of support.  相似文献

Background: Anxiety and depression have been linked to repetitive negative self-regulation styles in the form of worry and rumination respectively. Following predictions of the metacognitive model [Wells, A., & Matthews, G. (1994). Attention and emotion: A clinical perspective. Hove: Erlbaum], the current study compared the effect on recovery from stress of three strategies: worry, rumination, and distraction using a stress exposure paradigm. It was predicted that worry and/or rumination would be associated with delayed recovery on physiological and/or self-report indices when compared to distraction.

Method: Fifty-four participants were randomly assigned to one of the self-regulation conditions and then completed a modified version of the Trier Social Stress Test [TSST; Kirschbaum, C., Pirke, K. M., & Hellhammer, D. H. (1993). The “TSST” – A tool for investigating psychobiological stress responses in a laboratory setting. Neuropsychobiology, 28, 76–81. doi:10.1159/000119004]. Skin conductance and negative affect (NA) measurements were obtained at six different time points.

Results: Skin conductance indicated a prolonged recovery in the rumination condition when compared with the distraction condition. Individuals in the worry condition reported an immediate-delayed recovery from stress marked by higher NA scores in comparison to the distraction condition.

Conclusions: These findings may provide important insights into the effects of different forms of repetitive negative thinking on physiological and psychological recovery from stress. The different response patterns observed are discussed within the context of the metacognitive model.  相似文献

This study investigated the role of four recovery experiences during lunch break for employees’ afternoon well‐being. We hypothesized that lunch‐break recovery experiences (psychological detachment, relaxation, control, and relatedness) reduce afternoon exhaustion and enhance afternoon work engagement via replenished personal resources (i.e., state of being recovered immediately after break and subsequent self‐efficacy regarding the upcoming tasks in the afternoon). One hundred and nine employees provided daily survey data three times a day (i.e., start of work, after lunch break, end of work) over a period of two workweeks. Multilevel path analysis showed that relaxation, control, and relatedness during lunch break negatively predicted afternoon exhaustion and positively predicted afternoon work engagement via state of being recovered. For relaxation and relatedness, we additionally found positive serial indirect effects on afternoon work engagement via state of being recovered and self‐efficacy. Psychological detachment was not related to personal resources and afternoon well‐being. This study demonstrates that experiencing control over lunch break and using the lunch break to relax and to relate to others are indirectly associated with improved afternoon well‐being via replenished personal resources.

Practitioner points

  • Relaxation, control, and relatedness constitute lunch‐break recovery experiences that indirectly foster feeling confident, replenished, and engaged in the afternoon.
  • Employees should strive to spend their lunch breaks in ways that help them feel relaxed, related, and in control.
  • Organizations should provide their employees with sufficient break control and offer environments that facilitate relaxation and socializing during lunch break.

This study explored women’s lived recovery experiences from alcohol use disorder (AUD) facilitated by Alcoholics Anonymous (AA). The women (n?=?10; age range 30–62 years; married?=?6) completed life story interviews regarding their recovery from AUD with AA participation. Discourse analysis of the interview data yielded themes to suggest the women characterise their recovery as spiritual growth, a healing process with reliance of a higher authority, renewed purpose of life, and actively engaging rehabilitation. Spirituality appears a key resource in women’s AUD recovery.  相似文献

This study examines the mechanisms through which experiences in the home domain influence work performance by bringing together the literature on recovery and the work-family interface. A longitudinal study among 123 employees from different organizations was conducted to investigate whether need for recovery and home-work interference (HWI) impeded concentration at work 1 month later, and whether concentration adversely affected in-role performance over time. Structural equation modeling analysis supported these hypotheses. Whereas need for recovery and HWI had negative, lagged effects on concentration, concentration had a positive lagged effect on in-role performance. Moreover, need for recovery and HWI were reciprocal and negatively related over time, suggesting that these two states may create a negative spiral in the home domain that could easily intrude into the work domain. These findings increase our insight in the processes leading to reduced performance at work, and suggest that organizations should facilitate opportunities for recovery.  相似文献

A self-administered questionnaire was answered by 2014 drivers, 853 of whom were taking a course. The data were analyzed aiming to identify the factors that are linked to taking the course, i.e. to recurrent reoffending.The course-takers, of whom 89% were male, admitted committing more violations than the control group. They had more accidents. More male course-takers than controls reported not being happy, and they more frequently had high extroversion scores.The multivariate analysis showed that, among men, taking the course was associated with the mileage, the feeling of being almost certain to be charged for an offence and having a high risk of losing one’s licence, in addition to being young, having a large number of brothers and sisters, higher socio-occupational category and smoking. Among women, in spite of the small number of them on the course, the mileage, the feeling of having a high risk of losing one’s licence, driving alone, the mental representation of their own vehicle as an extension of their office, and defining themselves as liking to take risks during leisure activities were significantly linked to taking a points recovery course.Those taking the course were not therefore doing so by chance; they differed from the general population of drivers, which was also precisely described with regard to driving habits and representations.Recommendations are then made in order to redirect the content of courses more towards introspection than technical matters.  相似文献

Evidence suggests that a high percentage of people with a psychiatric disability can recover--find meaningful work, develop positive relationships, and participate fully in their communities. Evidence also suggests that work is an essential component of recovery. However, few people with a serious psychiatric disability are actually employed and most of those who are employed work only part-time at barely minimum wages.To assess the impact of federal programs such as Social Security Disability Insurance, vocational rehabilitation, medical insurance, and psychiatric services upon employment, we conducted a qualitative study of 16 employed and 16 unemployed individuals with psychiatric disabilities. All of our participants had disabilities severe enough to qualify them for Social Security Disability benefits.They told us that current federal policies and practices encouraged employment and integration of only a few participants, in a particular stage of their recovery, and placed significant barriers in the employment path of others.  相似文献

While previous work on mindfulness has focused predominantly on the benefits of mindfulness and of mindfulness interventions, the present article addresses the question of how natural experiences of mindfulness can be promoted in the context of work. Accordingly, this article sheds light on day‐to‐day fluctuations in workload and recovery experiences (psychological detachment and sleep quality) as antecedents of state mindfulness. Furthermore, this study extends extant research that has documented beneficial effects of mindfulness on subsequent recovery experiences by arguing that the relationship between mindfulness and recovery experiences is reciprocal rather than unidirectional. Using an experience‐sampling design across five workdays and involving three daily measurement occasions, we found that sleep quality and workload were related to subsequent levels of mindfulness. While not displaying a significant direct relationship with mindfulness, psychological detachment was indirectly related to mindfulness via sleep quality. Fatigue was identified as an important mechanism explaining these relationships. Furthermore, findings confirmed that the relationship between mindfulness and recovery experiences is reciprocal rather than unidirectional. Taken together, this study contributes to an enriched understanding of the role of mindfulness in organizations by shedding light on factors that precede the experience of mindfulness and by pointing to the existence of gain spirals associated with recovery experiences and mindfulness.

Practitioner points

  • Organizations seeking to promote mindfulness among their workforce should try to keep workload to a manageable degree.
  • Organizations may also pay attention to care for employees' day‐to‐day recovery as it has been shown to facilitate mindfulness.

This research examines organizational attempts to recover internally from ethical failures witnessed by employees. Drawing on research on service failure recovery, relationship repair, and behavioral ethics, we investigate how witnessing unethical acts in an organization impacts employees and their relationship with their organization. In two studies—one in the lab and one in the field—we examine the extent to which it is possible for organizations to recover fully from these ethical lapses. Results reveal an ethical recovery paradox, in which exemplary organizational efforts to recover internally from ethical failure may enhance employee perceptions of the organization to a more positive level than if no ethical failure had occurred.  相似文献

This study examines the impact of work-related smartphone use on daily recovery from work-related efforts. The literature shows that work–home interference (WHI) is an important inhibitor of the recovery process. We propose that the extensive use of smartphones with its implicit request of 24/7 availability inhibits the process of engaging in activities that are required for daily recovery. A total of 80 employees (40 smartphone users, 40 controls) completed a 6-day diary questionnaire over a time period of 2 weeks. Contrary to our hypothesis, smartphone users did not experience more overall WHI than nonusers. Furthermore, four activities aimed at recovery were examined. We predicted that daily WHI would increase employees’ engagement in recovery activities, but only if they did not use a smartphone. Results showed that, for the control group, WHI was positively related to psychological detachment, relaxation, mastery, and control activities, whereas smartphone users facing high WHI did not succeed in engaging in these recovery activities. This implies that being connected to work in the evening hours through smartphones has consequences for the extent to which employees succeed in undertaking recovery activities.  相似文献
