In rehabilitation, rhythmic acoustic cues are often used to improve gait. However, stride-time fluctuations become anti-persistent with such pacing, thereby deviating from the characteristic persistent long-range correlations in stride times of self-paced walking healthy adults. Recent studies therefore experimented with metronomes with persistence in interbeat intervals and successfully evoked...

People often recognize same-race faces better than other-race faces. This cross-race effect (CRE) has been proposed to arise in part because learners devote fewer cognitive resources to encode faces of social out-groups. In three experiments, we evaluated whether learners' other-race mnemonic deficits are due to "cognitive disregard" during study and whether this disregard is under metacognitiv...

Premovement, sensory, and cognitive brain potentials were recorded from patients with Chronic Fatigue Syndrome (CFS) in four tasks: i) target detection, ii) short-term memory, iii) self-paced movement, and iv) expectancy and reaction time (CNV). Accuracy and reaction times (RTs) were recorded for tasks i, ii, and iv. Results from CFS patients were compared to a group of healthy normals. Reactio...

Mental fatigue induced by an earlier cognitive task can impair performance on a subsequent physical task. The current study investigated whether such impairment could be mitigated feedback. In experimental sequential-task design, 63 sport science students completed series of three tasks: 5-min (pre-test), 20-min cognitive, (post-test). Participants were randomly allocated to one groups: feedbac...

OBJECTIVES To examine the effects of sleep restriction on firefighters' physical task performance during simulated wildfire suppression. METHODS Thirty-five firefighters were matched and randomly allocated to either a control condition (8-hour sleep opportunity, n = 18) or a sleep restricted condition (4-hour sleep opportunity, n = 17). Performance on physical work tasks was evaluated across ...

Stowe (1989) reported that semantic information eliminates garden paths in sentences with the direct-object vs. subject ambiguity, such as Even before the police stopped the driver was very frightened. Three experiments are presented which addressed some methodological problems in Stowe's study. Experiment 1, using a word-by-word, self-paced reading task with grammaticality judgements, manipula...

Do perfectionists try harder? Previous research on perfectionism and effort has used self-report items and task performance as indicators of effort. The current study investigated whether individual differences in perfectionism predicted effort-related cardiac activity during a mental effort task. Based on past research that suggests adaptive perfectionism is associated with higher effort, it w...

PM, Propositional Model, is a highly interactive model of language comprehension which can be contrasted with language processing models which assume an autonomous syntactic component. Models assuming an autonomous syntax can be divided into two basic types: (a) Strong Autonomy Models which assume that only the part of speech of lexical items is available to the syntactic analyzer, and (b) Weak...

This study reports results from a sentence completion task and a self-paced reading experiment examining relative clause (RC) attachment preferences in native speakers of Greek. To determine the role of lexical-semantic as well as referential context information for RC attachment, we examined two constructions under different context conditions: RCs preceded by complex noun phrases with genitiv...
