This paper reports the results of 2 studies that examine the perceptions of individuals attempting to generate random sequences. It was hypothesized that erroneous perceptions dominate probability judgment. The first study demonstrated that subjects verbalized significantly more erroneous than accurate perceptions when generating sequences of random binary events. The second study was designed both to replicate these data and to assess the role of motivation on the frequency of misconceptions. Results showed that the total number of erroneous perceptions again outnumbered accurate perceptions but, motivation did not increase the number of misconceptions. A basic error concerned subjects' inability to consider events as being independent of each other. The theoretical and practical implications of these results are discussed in relation to the psychology of gambling. 相似文献

The present study sought to determine the convergent validity of two macroscopic marital interaction coding systems: the Marital Interaction Coding System-Global and the Global Couple Interaction Coding System. The sample consisted of 40 couples who completed the Dyadic Adjustment Scale, the Potential Problem Checklist and a 30-min problem solving interactional task. Filmed interactions were coded by separate teams of observers using the Marital Interaction Coding System-Global and the Global Couple Interaction Coding System. Results showed that interobserver agreement, as assessed through intraclass correlations, was satisfactory for both coding systems. Between-system comparisons revealed that convergent validity coefficients were moderate; thus, it seems premature to conclude that macroscopic coding systems are interchangeable. Finally, multiple regression analyses indicated that both systems contained significant non-redundant behavioral predictors of marital adjustment. Implications of these results are discussed. 相似文献

This study predicted stable social maladjustment at ages 10, 11, and 12 from teacher behavioral ratings in kindergarten and a measure of family demographics. Kindergarten teachers rated 1,034 boys on hyperactivity, aggression, inattention, anxiety–withdrawal, and prosocial behavior. Sociodemographic information was collected from the parents. At ages 10, 11, and 12, teacher, parent, peer, and self-report behavior ratings were collected on 743 boys. School achievement was documented from school records. Boys whose average scores on each of the five behavioral ratings across ages 10, 11, and 12 were above the 90th percentile according to at least two informants were defined as having stable behavioral problems. From teacher ratings collected in kindergarten and family demographics, logistic regression analyses predicted stable social maladjustment. For each negative outcome there was a unique set of predictors. The results are discussed with reference to the early identification of children who are at risk.This research was supported by a grant from the Conseil Québécois de la Recherche Sociale.

It is well known that, in France, this important movement, which originated in Port-Royal, did not remain exactly on the same basis during its development. In this paper we attempt to show how a new concept (the logical analysis of sentence from phrase) was proposed by Du Marsais (see grammatical articles of the Encyclopédie), Beauzée (1767) and, finally, Letellier (1805, 1811). 相似文献

Effects of dual-responding on tracking performance after 49-h of sleep deprivation (SD) were evaluated behaviorally and with functional magnetic resonance imaging (fMRI). Continuous visuomotor tracking was performed simultaneously with an intermittent color-matching visual detection task in which a pair of color-matched stimuli constituted a target and non-matches were non-targets. Tracking error means were binned time-locked to stimulus onset of the detection task in order to observe changes associated with dual-responding by comparing the error during targets and non-targets. Similar comparison was made with fMRI data. Our result showed that despite a significant increase in the overall tracking error post SD, from 20 pixels pre SD to 45 pixels post SD, error decreased to a minimum of about 25 pixels 0-6s after dual-response. Despite an overall reduced activation post SD, greater activation difference between targets and non-targets was found post SD in task-related regions, such as the left cerebellum, the left somatosensory cortex, the left extrastriate cortex, bilateral precuneus, the left middle frontal gyrus, and the left motor cortex. Our results suggest that dual-response helps to alleviate performance impairment usually associated with SD. The duration of the alleviation effect was on the order of seconds after dual-responding. 相似文献

Age-related decline in auditory perception reflects changes in the peripheral and central auditory systems. These age-related changes include a reduced ability to detect minute spectral and temporal details in an auditory signal, which contributes to a decreased ability to understand speech in noisy environments. Given that musical training in young adults has been shown to improve these auditory abilities, we investigated the possibility that musicians experience less age-related decline in auditory perception. To test this hypothesis we measured auditory processing abilities in lifelong musicians (N = 74) and nonmusicians (N = 89), aged between 18 and 91. Musicians demonstrated less age-related decline in some auditory tasks (i.e., gap detection and speech in noise), and had a lifelong advantage in others (i.e., mistuned harmonic detection). Importantly, the rate of age-related decline in hearing sensitivity, as measured by pure-tone thresholds, was similar between both groups, demonstrating that musicians experience less age-related decline in central auditory processing. 相似文献
