TL;DR: The sorts of evidence that have contributed to the fragmentation, if not the death, of an all-purpose short-term memory system have nonetheless advanced the knowledge of related cognitive processes.

TL;DR: In this article, the decomposition of immediate acts when structuring decision problems is examined, and seven different types of uncertainties are identified, and four of these are taken explicitly into account in models within the province of decision theory, described in terms of four interlocking systems interfaced with semantic memory.

TL;DR: In this paper, the authors explore the effects of requiring that two possible responses use the same finger or hand in some conditions of the experiment and find that multiple response preparation occurs prior to detection of the reaction signal, whereas when the two possible response are made with different fingers of the same hand it appears that advance preparation is limited to a single response.

TL;DR: In this article, the authors compare a number of motor control theories according to the form of control they exhibit and according to their ability to address issues in the area of human motor control.

TL;DR: It was found that varying the internal representation of one and the same sequence of taps affects the performance in a predictable way.

TL;DR: Two general types of visual persistence are tentatively identified: one resides in activity along the afferent visual pathway and is retinotopically organized; the other resides at central levels and is spatiotopicallyorganized.

TL;DR: Three approaches to a theoretical analysis of confidence judgments are considered: one linking confidence to the number of sensory observations, one based on a distinction between ‘state’ and ‘process’ factors, and a ‘balance of evidence’ hypothesis developed from an accumulator model of discrimination.

TL;DR: In this paper, both expert and novice subjects had difficulty generating complete sets of hypotheses and were overconfident in their subjective judgments of the probabilities of the generated hypotheses in an automobile trouble-shooting inference task.

TL;DR: In this article, the authors examined the relationship between the performance of a piece of music and its notated counterpart (the score) and found that the expressive characteristics of musical performances are related to structural characteristics of the music performed.

TL;DR: A brief review of the literature, and three experiments, are presented which investigated time of day effects in human performance at simple repetitive tasks (i.e. tasks involving little or no working memory load).

TL;DR: This article reported two experiments concerning the effects of word age-of-acquisition and other word attributes on speed of lexical decision and found that word length, frequency and familiarity were the major determinants of decision speed.

TL;DR: The mutual relations among the reaction variables did not change after sleep loss which argues in favor of the robustness of these relations, and, consequently, of the applicability of linear stage models to reaction processes.

TL;DR: This paper showed that the degree to which probability assessment tasks are seen in terms of certainty or total uncertainty appears to be a consistent individual difference between sets of past and future event questions with task difficulty held constant.

TL;DR: The prediction that this condition will generate more efficient time-sharing is tested and the separate “spatial’ and “verbal” resource demands of the two variants are established by observing their differential interference with concurrent spatial and verbal tasks.

TL;DR: This paper found that the feeling of knowing in the tip-of-the-tongue (TOT) states interfered with a subject's ability to perform well on a concurrent task.

TL;DR: In this paper, the dual-mechanism theory of recall is applied to the results of some previous experiments investigating recall with different types of cue, and two experiments are reported which allow these predictions to be tested.

TL;DR: In this article, a series of five experiments showed that a movement of a finger of one hand has a shorter latency if the alternative movement with the other hand is of the same form than in case of different forms, indicating that programming of the form of a movement is at least partly independent of the muscles involved in movement execution.

TL;DR: In this paper, the authors test the hypothesis that individuals differ in their use of the representativeness heuristic and find that there is no evidence of a correlation between the two types of errors.

TL;DR: It is proposed that an additive or interactive relationship between stimulus intensity and FP can be inferred only when the mental processes called for by the various uses of FP are simultaneously considered.

TL;DR: The concept of S-R-compatibility did not cover the pattern of results but that the concept of ideomotor compatibility did, and an increase in reaction time with the number of tactual choices was found with weak vibrations, but not with strong vibrations.

TL;DR: The present results are consistent with the view that size and direction of immediate arousal as exerted by intense stimuli are regulated by foreperiod duration as well as by the demands placed upon the response choice mechanism.

TL;DR: The pattern of main effects and interactions suggested that the same model of information flow described both single- and dual-tasks conditions; i.e., visual and auditory stimuli were encoded separately but shared capacity at the response selection stage.

TL;DR: It is suggested that a major effect of noise is to bias the allocation of effort towards the operation which appears to best repay the investment of more effort.

TL;DR: In this study sequential bias in randomized response sequences is simulated by computer and can be explained by the assumption that subjects try to control perseveration tendencies by using a comparison-based memory search mechanism.

TL;DR: Overall performance capacity appeared to be greatest at menstruation, and the degree of attentional selectivity was least, a finding typical of stressor variables.

TL;DR: It is suggested that the effect of noise on memory is not a uniform and mechanical exaggeration of dominance, but depends on the retrieval strategies being employed by the particular subject.

TL;DR: The results show a regular costs-benefit function for central signals and a complete absence of costs- benefit trade-off for peripheral signals, consistent with a resource volume theory and in the context of Posner's (1980) notions on covert orienting of attention.

TL;DR: In a previous study as discussed by the authors, Heuer found shorter binary choice RTs for finger movements of the right hand when the alternative movement with the left hand was of the same form that in case of different forms.

TL;DR: It was found that a more pronounced effect of sleep loss occurred when two signals are successively presented, but not when the signals are simultaneously viewed, while preceded by a shift of gaze.
