This study was designed to assess the impact of social support on poststressor cognitive impairment, with the goal of providing a laboratory test of the buffering hypothesis of social support. High or low support was operationahzed as the warm or the neutral behavior of an interviewer, which preceded the experimental stressor, high or low task load Subjects were 32 nonpsychotic female psychiatr...

Many-Task Computing (MTC) is a widely used computing paradigm for large-scale task-parallel processing. One of the key issues in MTC is to schedule a large number of independent tasks onto heterogeneous resources. Traditional task-level scheduling heuristics, like Min-Min, Sufferage and MaxStd, cannot readily be applied in this scenario. As most of MTC tasks are usually fine-grained, the resour...

The rate monotonic scheduling algorithm is a commonly used task scheduling algorithm for periodic realtime task systems. This paper discusses feasibility decision fo r a given real-time task system b y the rate monotonic scheduling algorithm. It presents a new necessary a n d suficient condition fo r a given task system to be feasible, and a new feasibility decision algorithm based on that cond...

In this paper, we evaluate the performance of several robust speech recognition algorithms in a noisy automobile environment as characterized by the Finnish SpeechDat–Car ASR task [1]. By applying acoustic feature compensation, model compensation, and speech detection algorithms to this task, a 51% reduction in word error rate (WER) was obtained relative to the ETSI standard ASR front–end. In a...

Visual exploration and planning of actions are reported to be abnormal in schizophrenia. Most of the studies monitoring eye movements in patients with schizophrenia have been performed under free-viewing condition. The present study was designed to assess whether mentally performing an action modulates the visuomotor behavior in patients with schizophrenia and in healthy controls. Visual scan p...

Sequence-specific postural motor learning in a target-directed weight-shifting task in 12 older and 12 young participants was assessed. In the implicit sequence learning condition participants performed a concurrent spatial cognitive task and in the two explicit conditions participants were required to discover the sequence order either with or without the concurrent cognitive task. Participant...

I used a novel effect of adaptation to a moving stimulus to investigate the role of attention in the processing of motion-in-depth (MID). Following adaptation to expansion, the time required to detect an expanding target in the same location as the adaptation target was significantly longer than following viewing of a constant-sized target. Conversely, following adaptation to contraction, detec...

The effect of a sequentially presented memory scanning task on rule-based and information-integration category learning was investigated. On each trial in the short feedback-processing time condition, memory scanning immediately followed categorization. On each trial in the long feedback-processing time condition, categorization was followed by a 2.5-sec delay and then memory scanning. In the c...

BACKGROUND AND OBJECTIVES Previous studies have demonstrated that some individuals suffering from obsessive-compulsive disorder (OCD) are impaired in verbal memory performance. This study was designed to investigate the role of cognitive self-consciousness (CSC) as a putative underlying mechanism of these cognitive deficits. METHODS Verbal memory performance of 36 participants with OCD, 36 in...

The neural correlates of cognitive control in a picture-word interference task were investigated in 13 healthy individuals using event-related potentials. The differences between the incongruent condition and the congruent condition were examined. Behavioral data showed that the task yielded a robust interference effect as indexed by a longer reaction time for the incongruent condition. Scalp e...
