SenseCam is a wearable digital camera that captures an electronic record of the wearer's day. It does this by automatically recording a series of still images through its wide-angle lens, and simultaneously capturing a log of data from a number of built-in electronic sensors. Subsequently reviewing a sequence of images appears to provide a powerful autobiographical memory cue. A preliminary evaluation of SenseCam with a patient diagnosed with severe memory impairment was extremely positive; periodic review of images of events recorded by SenseCam resulted in significant recall of those events. Following this, a great deal of work has been undertaken to explore this phenomenon and there are early indications that SenseCam technology may be beneficial to a variety of patients with physical and mental health problems, and is valuable as a tool for investigating normal memory through behavioural and neuroimaging means. Elsewhere, it is becoming clear that judicious use of SenseCam could significantly impact the study of human behaviour. Meanwhile, research and development of the technology itself continues with the aim of providing robust hardware and software tools to meet the needs of clinicians, patients, carers, and researchers. In this paper we describe the history of SenseCam, and the design and operation of the SenseCam device and the associated viewing software, and we discuss some of the ongoing research questions being addressed with the help of SenseCam. 相似文献

SenseCam improves memory for recent events and quality of life in a patient with memory retrieval difficulties 总被引:1,自引:0,他引:1

A wearable camera that takes pictures automatically, SenseCam, was used to generate images for rehearsal, promoting consolidation and retrieval of memories for significant events in a patient with memory retrieval deficits. SenseCam images of recent events were systematically reviewed over a 2-week period. Memory for these events was assessed throughout and longer-term recall was tested up to 6 months later. A written diary control condition followed the same procedure. The SenseCam review procedure resulted in significantly more details of an event being recalled, with twice as many details recalled at 6 months follow up compared to the written diary method. Self-report measures suggested autobiographical recollection was triggered by the SenseCam condition but not by reviewing the written diary. Emotional and social wellbeing questionnaires indicated improved confidence and decreased anxiety as a result of memory rehearsal using SenseCam images. We propose that SenseCam images provide a powerful boost to autobiographical recall, with secondary benefits for quality of life. 相似文献

Personality traits prior to the onset of illness or disability may influence how well an individual psychologically adjusts after the illness or disability has occurred. Previous research has shown that after the onset of a disability, people initially experience sharp drops in life satisfaction, and the ability to regain lost life satisfaction is at best partial. However, such research has not investigated the role of individual differences in adaptation to disability. We suggest that predisability personality determines the speed and extent of adaptation. We analyzed measures of personality traits in a sample of 11,680 individuals, 307 of whom became disabled over a 4-year period. We show that although becoming disabled has a severe impact on life satisfaction, this effect is significantly moderated by predisability personality. After 4 years of disability, moderately agreeable individuals had levels of life satisfaction 0.32 standard deviations higher than those of moderately disagreeable individuals. Agreeable individuals adapt more quickly and fully to disability; disagreeable individuals may need additional support to adapt. 相似文献

The present study assessed business students’ responses to an innovative interactive presentation on academic integrity that
employed quoted material from previous students as launching points for discussion. In total, 15 business classes (n = 412 students) including 2nd, 3rd and 4th year level students participated in the presentations as part of the ethics component
of ongoing courses. Students’ perceptions of the importance of academic integrity, self-reports of cheating behaviors, and
factors contributing to misconduct were examined along with perceptions about the presentation. Discussion sessions revealed
that academic misconduct is a complex issue. For example, knowledge of what constitutes misconduct was not consistent across
domains (e.g. exam contexts versus group work), penalties were not wholly known, and there was variation in perceived responsibility
for reporting and representing academic integrity. Survey measures revealed that self-reported academic misconduct was more
prevalent than expected with only 7.5% of students indicating they had never cheated in any way. Furthermore, results showed
gender and year of study as predictive factors for issues related to academic misconduct. In general, students were receptive
to this form of presentation. The implications of such instructional interventions for enhancing ethical behaviors in higher
education classrooms are discussed. 相似文献

Quiet-eye training for soccer penalty kicks 总被引:1,自引:0,他引:1
Anxiety has been shown to disrupt visual attention, visuomotor control and subsequent shot location in soccer penalty kicks.
However, optimal visual attention has been trained in other far aiming skills, improving performance and resistance to pressure.
We therefore asked a team of ten university soccer players to follow a quiet eye (QE; Vickers 1996) training program, designed to align gaze with aiming intention to optimal scoring zones, over a 7-week period. Performance
and gaze parameters were compared to a placebo group (ten players) who received no instruction, but practiced the same number
of penalty kicks over the same time frame. Results from a retention test indicated that the QE-trained group had more effective
visual attentional control, were significantly more accurate, and had 50% fewer shots saved by the goalkeeper than the placebo
group. Both groups then competed in a penalty shootout to explore the influence of anxiety on attentional control and shooting
accuracy. Under the pressure of the shootout, the QE-trained group failed to maintain their accuracy advantage, despite maintaining
more distal aiming fixations of longer duration. The results therefore provide only partial support for the effectiveness
of brief QE training interventions for experienced performers. 相似文献

Perceptions of defeat have been linked to a range of clinical disorders including psychosis. Perceived defeat sometimes increases in response to failure, but the strength of this association varies between individuals. The present research investigated whether trait reappraisal, a thought-focused coping style, amplified response to stressful events. Two studies (Study 1, n = 120 nonclinical participants; Study 2, n = 77 participants with schizophrenia-spectrum disorders) investigated whether trait reappraisal amplified feelings of defeat following an experience of failure versus success. Frequent reappraisers showed the largest increases in subjective defeat after failure versus success in both studies, with nonclinical participants with greater habitual reappraisal also showing larger increases in sadness and general negative affect. Frequent use of reappraisal may confer vulnerability to subjective defeat in response to stressful life events among nonclinical and clinical populations and could be an area for relapse prevention interventions to target. 相似文献

Two studies examined whether perceiving a partner as responsive leads people to be more expressive with that partner, and whether the effects of perceived partner responsiveness on expressivity are moderated by self-esteem. In Study 1, female undergraduates with high or low self-esteem disclosed to a fictitious partner about a sad event. Participants either received an understanding, caring, and validating written response from their ostensible partner or did not receive a response. In Study 2, participants wrote an email, supposedly to another participant, about a sad event and received either a highly responsive or a non-responsive email response. In both studies, partner responsiveness increased expressivity among individuals with low self-esteem but not among individuals with high self-esteem. These results provide the first experimental evidence for Reis and Shaver's (1988) theorizing about responsiveness and self-disclosure. 相似文献

Modeling activity-based anorexia, food-deprived rats consistently show that activity increases as weight decreases. This effect was explored in 8 food-deprived, Sprague-Dawley rats as potentially mediated by intrinsic value of activity. Running-wheel activity rates were recorded for free-fed weight, reduction to 90% of free-fed weight, and to 80% of free-fed weight. As expected, activity increased as weight decreased. Further, significant differences appeared in the trends of individual run rates when compared across all trials. These individual trends were expressed as varied rates of running, with extreme high and low run rates prevalent. The rewarding nature of exercise itself might serve to predict these trends in individual rats and reveal potential indicators for the development of activity-based anorexia. 相似文献

What are the psychological mechanisms that trigger habits in daily life? Two studies reveal that strong habits are influenced by context cues associated with past performance (e.g., locations) but are relatively unaffected by current goals. Specifically, performance contexts—but not goals—automatically triggered strongly habitual behaviors in memory (Experiment 1) and triggered overt habit performance (Experiment 2). Nonetheless, habits sometimes appear to be linked to goals because people self-perceive their habits to be guided by goals. Furthermore, habits of moderate strength are automatically influenced by goals, yielding a curvilinear, U-shaped relation between habit strength and actual goal influence. Thus, research that taps self-perceptions or moderately strong habits may find habits to be linked to goals. 相似文献
