Several authors have investigated the risks arising from the growth in mobile phone use (e.g. debts incurred by young people). The aims of the present study are (1) to validate a new questionnaire assessing problematic mobile phone use: the Problematic Mobile Phone Use Questionnaire (PMPUQ), and (2) to investigate the relationships between the PMPUQ and the multi‐faceted construct of impulsivity. With these aims, 339 subjects were screened using the PMPUQ and the UPPS Impulsive Behaviour Scale (UPPS) which assesses four distinct components associated with impulsive behaviours (urgency, lack of premeditation, lack of perseverance and sensation seeking). The results showed that the PMPUQ has an acceptable fit and assesses four different dimensions of problematic mobile phone use (prohibited use, dangerous use, dependence, financial problems). While each facet of impulsivity played a specific role in mobile phones use, urgency appeared to be the strongest predictor of problematic use. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Path dependent preferences: The role of early experience and biased search in preference development 总被引:2,自引:0,他引:2

What is the role of early experiences in shaping preferences? What are the mechanisms by which such early encounters influence the way preferences are formed? In this research, we examine the impact of the entry position and favorability of initial (and ongoing) experiences on preference development. We predict that the starting point will heavily influence which particular region people select from initially, and favorableness of early experiences and myopic search will both limit their search to that particular region. Across four studies, we find that when the initial experiences are favorable, subjects engage in lower levels of search, experience only a narrow breadth of possible alternatives, demonstrate less ongoing experimentation, and have a reduction in the amount of preference development. 相似文献

We investigated the word-list-learning performance of younger and older adults over 4 consecutive days at different times of day to study age-related differences in consistency of performance over time and the influence of circadian variation on performance. Eighteen younger (M age, 23.4 years) and 18 older (M age, 73.3 years) men and women participated. The start time of testing alternated between morning and early evening across the 4 days of testing. On each test day, participants learned a different list of 15 unrelated words over four learning trials. As expected, younger adults performed better than older adults on immediate recall, delayed recall, and recognition. Contrary to our expectations, time of day did not significantly influence recall or recognition performance in either the older or younger adults. Older adults did show a greater incidence of false memory (i.e., previously learned list intrusions in free recall and false alarms in recognition) than younger adults. Older adults also exhibited greater intra-individual performance variability on the measures of false memory across test days. This variability was not related to circadian variation. False memory and variability of performance have both been linked to frontal systems dysfunction. The findings presented here are consistent with the notion that changes in cognition with aging in part reflect age-related decline in frontal lobe function. 相似文献

Although socio‐emotional changes are very frequently encountered after traumatic brain injury (TBI), the psychological mechanisms underlying these disorders are still poorly understood. This study aimed to explore the relationships between dysexecutive syndrome (assessed with the Behavioural Assessment of the Dysexecutive Syndrome [BADS]) and socio‐emotional changes assessed by the Iowa scales of personality change (ISPC) in patients with TBI. The BADS was thus administered to 25 patients with TBI and to 25 healthy controls. Simultaneously, a close relative of each patient was given the ISPC in order to assess socio‐emotional changes. Results indicated that patients displayed significantly lower executive performances than controls and experimented significant socio‐emotional changes. The Modified Six Elements Test was the only subtask of the BADS to be significantly related to behavioural changes, and more specifically to externalizing disorders. It is concluded that executive functions, and especially multitasking, encompass processes whereby one can consciously control one's emotional reactions and behaviours. 相似文献

The aim of the study was to use cognitive neuropsychological analysis to investigate object‐based visual processing skills in children with spina bifida myelomeningocele and hydrocephalus (SBH). Fourteen children with SBH (aged 8–12) and 21 age‐, socio‐economic status‐, and Verbal IQ‐matched healthy controls were assessed using the Birmingham Object Recognition Battery. Overall, the performance of the children with SBH on the object‐processing tasks was intact, indicating normal development of the ventral visual processing pathway. While the initial results indicated that the children with SBH performed statistically significantly less accurately on some tasks, these group differences no longer met significance criteria after capacity for sustained attention was statistically controlled. 相似文献

Research has established that challenging memory goals always lead to score increases for younger adults, and can increase older adults' scores under supportive conditions. This study examined beliefs and on-task effort as potential mechanisms for these self-regulatory gains, in particular to learn whether episodic memory gains across multiple trials of shopping list recall are controlled by the same factors for young and old people. Goals with feedback led to higher recall and strategic categorisation than a control condition. Strategy usage was the strongest predictor of gains over trials for both age groups. Age, goal condition, and effort also predicted scores across the entire sample. Older adults' gains, but not younger adults' gains, were affected significantly by the interaction of self-efficacy beliefs and goal condition, and condition interacted with locus of control to predict younger adult gains. These results emphasise the importance of self-regulatory effort and positive beliefs for facilitating goal-related memory gains. 相似文献

Response times on test items are easily collected in modern computerized testing. When collecting both (binary) responses
and (continuous) response times on test items, it is possible to measure the accuracy and speed of test takers. To study the
relationships between these two constructs, the model is extended with a multivariate multilevel regression structure which
allows the incorporation of covariates to explain the variance in speed and accuracy between individuals and groups of test
takers. A Bayesian approach with Markov chain Monte Carlo (MCMC) computation enables straightforward estimation of all model
parameters. Model-specific implementations of a Bayes factor (BF) and deviance information criterium (DIC) for model selection
are proposed which are easily calculated as byproducts of the MCMC computation. Both results from simulation studies and real-data
examples are given to illustrate several novel analyses possible with this modeling framework.

This study investigated the role of auditory selective attention capacities as a possible mediator of the well-established association between verbal short-term memory (STM) and vocabulary development. A total of 47 6- and 7-year-olds were administered verbal immediate serial recall and auditory attention tasks. Both task types probed processing of item and serial order information because recent studies have shown this distinction to be critical when exploring relations between STM and lexical development. Multiple regression and variance partitioning analyses highlighted two variables as determinants of vocabulary development: (a) a serial order processing variable shared by STM order recall and a selective attention task for sequence information and (b) an attentional variable shared by selective attention measures targeting item or sequence information. The current study highlights the need for integrative STM models, accounting for conjoined influences of attentional capacities and serial order processing capacities on STM performance and the establishment of the lexical language network. 相似文献
