Cognitive impairment is one of the most pronounced symptoms reported by patients with stress‐related mental health problems. Impairments related to executive function and to some extent speed and attention are therefore common in patients with stress‐related burnout/exhaustion. In this paper we present a follow‐up of cognitive performance in patients with stress‐related exhaustion several years after they initially sought medical care. Thirty patients and 27 healthy controls, mean age 49 years (SD 6.5) and 55 years (SD 6.7) respectively, were included, all of whom had undergone baseline measurements of neuropsychological functioning. The mean follow‐up time was three years. Half of the patients still reported mental health problems at follow‐up and over time no major changes in cognitive performance were noted. The patients still performed significantly poorer than controls with regard to cognitive functions, mainly related to speed, attention and memory function. Long‐lasting impairment of cognitive functions related to speed, attention and memory function noted in patients with stress‐related exhaustion should be acknowledged and taken into consideration during treatment and when discussing a return to work. Follow‐up periods longer than three years are needed to explore the persistence of the cognitive impairment. 相似文献

This study investigated the interplay between perceived investment in contract worker development by the client organization and contract workers' perceived organizational support from their temporary employment agency. A study among 2021 contract workers from three temporary employment agencies in Norway showed that the relationships between perceived investment in contract worker development and task and contextual performance were moderated by contract workers' perceived organizational support from the agency. The form of the moderations revealed no positive relationships between perceived investment in contract worker development and performance unless the perceived investment by the client organization was accompanied by higher levels of perceived support from the temporary employment agency. These findings suggest that client organizations, which hire from temporary employment agencies that provide support to their contract workers, will get the most out of their investments in these contract workers' development. 相似文献

Motivational sources of confirmation bias in criminal investigations: the need for cognitive closure
Karl Ask Pr Anders Granhag 《Journal of Investigative Psychology & Offender Profiling》2005,2(1):43-63
In two experiments, criminal investigators (N = 50) and undergraduate students (N = 68) read a set of facts from the preliminary investigation of a homicide case. Participants' initial hypothesis regarding the crime was manipulated by providing background information implying that the prime suspect had a jealousy motive or that there might be an alternative perpetrator. Students displayed a framing effect, such that guilt was ascribed to the prime suspect only when a potential motive was presented, whereas investigators did so regardless of hypothesis, thus being less sensitive to alternative interpretations. Investigators' need for cognitive closure (NFC) moderated the effect of the hypothesis on perceptions of the strength of the evidence against the prime suspect; high (v low) NFC investigators were less likely to acknowledge inconsistencies in the material when presented with a potential motive, but were more likely to do so when made aware of the possibility of an alternative perpetrator. Interpretations are somewhat clouded by the fact that dispositional NFC did not seem to affect in a consistent manner participants' motivation toward the experimental task.

This longitudinal, year‐long study compared sleep–wake state organization in two groups of infants–infants whose mothers abused substances during their pregnancies and nonexposed, typically developing, age‐matched comparison infants–to determine whether differences in sleep–wake state organization existed between the two groups. Seventeen infants of mothers who were participating in a parent–infant residential treatment program for substance abuse were enrolled. Their sleep–wake state organization over the first year of life was compared to that of 17 age‐matched comparison infants. The intent was to follow each infant on five occasions over the first year of life using established methods of time‐lapse videosomnography to record sleep–wake state organization; however, attrition in the substance‐abusing group was problematic. Some sleep–wake variables (i.e., Active Sleep%, Quiet Sleep%, Awake%, number of nighttime awakenings) were similar for both groups of infants at comparable ages across the first year. Total sleep time and the longest sustained sleep period (sleep continuity variables) differed significantly at some of the ages measured. Although overall sleep architecture appears highly resilient and well organized, some indications of sleep fragmentation and shortened nighttime sleep periods were observed in the substance‐exposed infants. More research is needed to explain why sleep‐continuity variables and not sleep‐state proportion variables differed between the two groups. 相似文献

The acoustic qualities of a room can have a deleterious effect on the quality of speech signals. The acoustic measurement of reverberation time (RT) has shown to impact second language (L2) speech comprehension positively when lower due to release from spectral and temporal masking effects as well as top-down processing factors. This auralization experiment investigated the benefits of better L2 vocabulary and executive function (updating) skills during L2 listening comprehension tests under shorter versus longer RT conditions (0.3 and 0.9?s). 57 bilingual university students undertook L2 vocabulary, number updating and L2 listening comprehension tests. After splitting groups into high/low vocabulary and updating groups, a mixed ANOVA was conducted. The high number updating group showed no significant differences or interactions in L2 listening comprehension than the lower number updating group across RT conditions. The high vocabulary group had 22% better L2 listening comprehension than the low vocabulary group in long RT, and 9% better in short RT. A significant benefit in L2 listening comprehension due to release from reverberation was only evident in the high vocabulary group. Results indicate that the benefit of good room acoustics for listening comprehension is greatest for those with better language (vocabulary) ability. 相似文献

The aim of the study was to explore if recall of words and recognition of sentences orally presented was affected by a background noise. A further aim was to investigate the role of working memory capacity in performance in these conditions. Thirty‐two subjects performed a word recall and a sentence recognition test. They repeated each word to ensure that they had heard them. A reading span test measured their working memory capacity. Performance on the word recall task was impaired by the background noise. A high reading span score was associated with a smaller noise effect, especially on recall of the last part of the word list. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Research with general knowledge items demonstrates extreme overconfidence when people estimate confidence intervals for unknown quantities, but close to zero overconfidence when the same intervals are assessed by probability judgment. In 3 experiments, the authors investigated if the overconfidence specific to confidence intervals derives from limited task experience or from short-term memory limitations. As predicted by the naive sampling model (P. Juslin, A. Winman, & P. Hansson, 2007), overconfidence with probability judgment is rapidly reduced by additional task experience, whereas overconfidence with intuitive confidence intervals is minimally affected even by extensive task experience. In contrast to the minor bias with probability judgment, the extreme overconfidence bias with intuitive confidence intervals is correlated with short-term memory capacity. The proposed interpretation is that increased task experience is not sufficient to cure the overconfidence with confidence intervals because it stems from short-term memory limitations. 相似文献

Bowlby (1969/1982, 1973, 1980) has proposed that internal working models of self and other are psychic structures that guide an individual's subjective experience of and responses to others in important relationships. They are termed “working” models because they are believed to be dynamic mental representations that are modifiable, although they are presumed to become more resistant to change after the early years. This paper reviews Bowlby's construct of internal working models, including some recent empirical evidence usefully explained by the construct. The authors apply the construct of working models to parents' subjective experiences of their infants and review some preliminary evidence that suggests that parental working models of their infants are present even prior to the infants' birth and influence the parents' perception and interpretation of the infants' characteristics and behaviors. The authors then consider the development of infants' working models of self and other in the context of parental attributions. They conclude that subjectivity in parent-infant relationships is an exciting and promising area for investigation, although, at present, future progress is limited by problems of measurement. A brief discussion of directions for future research is included. 相似文献

A proposed model for behavioral change is described as a process in several steps from habitual nonenvironmentally friendly behavior to environmentally friendly behavior. Every step is linked to factors promoting or impeding further progress. Data from a questionnaire addressed to a random sample of 500 Swedish adults supported the hypothesis that general factors such as environmental values and a sense of responsibility for the environment will be more influential in an early phase rather than in a later phase of changing established habits regarding purchases of washing and washing-up detergents, respectively. Furthermore, in a later phase of transition, specific beliefs about particular products will affect the testing and evaluation of a new behavior. 相似文献
