In the present study, a computerized test was used to compare the attention level of a group of healthy older participants aged 75 with that of a group of students aged 31. The second part of the study examined only the older participants and sought to discover how three measures of lifestyle were related to measures of attention. The results showed that the young group performed better on meas...

The array invariant method, previously derived for instantaneous range and bearing estimation of a single broadband impulsive source in a horizontally stratified ocean waveguide, can be generalized to simultaneously localize multiple uncorrelated broadband noise sources that are not necessarily impulsive in the time domain by introducing temporal pulse compression and an image processing techni...

Evidence from both human and animal studies suggests that sensitivity to rewarding stimuli is positively associated with impulsive behaviors, including both impulsive decision making and inhibitory control. The current study examined associations between the hedonic value of a sweet taste and two forms of impulsivity (impulsive choice and impulsive action) in healthy young adults (N = 100). Par...

Lower limb rehabilitation exoskeleton robots (LLRERs) play an important role in lower training and assistance walking for patients with movement disorders. In order to reduce eliminate adverse effects on the accuracy of human motion gait tracking during LLRER, which is caused by gravity friction, periodic ground shock force, human–exoskeleton interaction this paper proposes a feedforward–feedba...

Impulsive and convective frequencies are one of the most important subjects for evaluation of the seismic behavior of tanks. These two frequencies are defined by Housner and used for obtaining Rayleigh damping in time history analysis. ACI 350 and NZSEE standards have suggested some analytical solutions for finding convective and impulsive frequencies. These frequencies can also extract from mo...

This paper studies the stability of large-scale impulsive delay differential systems and impulsive neutral systems. By developing some impulsive delay differential inequalities and a comparison principle, sufficient conditions are derived for the stability of both linear and nonlinear large-scale impulsive delay differential systems and impulsive neutral systems. Examples are given to illustrat...

Impulsive choice is a common charactertistic among individuals with gambling problems, obesity, and substance abuse issues. Impulsive choice has been classified as a trans-disease process, and understanding the etiology of trait impulsivity could help to understand how diseases and disorders related to impulsive choice are manifested. The Western diet is a possible catalyst of impulsive choice ...

BACKGROUND Parkinson's disease (PD) is a degenerative brain disorder accompanied by the loss of dopaminergic neurons and the presence of motor and non-motor symptoms. OBJECTIVE We performed a cross-sectional, questionnaire-based analysis of impulsive behavior in our PD clinic population to assess prevalence and associated characteristics. RESULTS We found a higher prevalence of impulsive be...

A number of maladaptive behaviors and poor health outcomes (e.g., substance abuse, obesity) correlate with impulsive choice, which describes the tendency to prefer smaller, immediate rewards in lieu of larger, delayed rewards. Working memory deficits are often reported in those diagnosed with the same maladaptive behaviors. Human studies suggest that impulsive choice is associated with working ...

Young has proposed a schema mode model of borderline personality disorder (BPD), hypothesizing that BPD patients tend to flip from 1 of 4 maladaptive schema modes to another. The present study is the first empirical test of this model, investigating whether these 4 modes are specific for BPD patients and whether BPD-relevant stress specifically increases one of the modes, the detached protector...
