Most college-student readers have difficulty in detecting the letter F in instances of the word OF embedded in a single statement. Throughout a series of five experiments designed to clarify the basis of these detection failures, their unique and robust nature was demonstrated. The detection failures persisted in spite of repeated attempts to detect the letters by subjects who, in separate conditions and experiments, first memorized or copied the statement, or who, for purposes of comparison, also detected the O in OF, the N in ON, or the F in IF, or who read the statement in a number of physical formats, which included lower and upper letter cases, scrambled syntax, unsegmented letter strings, and vertical (list) presentation. Although many of these manipulations significantly improved performance, none produced perfect performance or performance comparable to the detection of F in IF. Several hypotheses, including those of redundancy, unitization, and phonetic recoding, were tested as explanations of the detection failures: The hypothesis that received the strongest support was that of phonetic recoding. This hypothesis focuses upon the atypical pronunciation of F as/v/(as in the word OF), rather than as the more typical/f/. In short, this reading illusion was concluded to be, in large part, a result of the subjects’ scanning their acoustic rather than their visual images of the printed word. 相似文献

In the first phase of an experiment reducing hostility through fantasy, 203 first and second-year high school students completed a daydreaming scale, Rotter ISB, and a sociometric scale designed to ascertain which of their peers behave aggressively. The students of the upper and lower quarters of the daydreaming scale were classified as high and low fantasy, and as aggressive or nonaggressive subjects. The second phase, two weeks later, consisted of 94 subjects forming three groups: a trait aggressive group, a nonaggressive control group, and a group of nonaggressive subjects experimentally manipulated for aggression. Half of the subjects composed stories to four high-cue aggressive TAT cards; the other half read neutral stories. All the subjects then again completed the Rotter ISB which was scored for aggression. Analysis of covariance of the scores indicated that a reduction in hostility occurred only for the group experimentally aroused to aggression in the TAT condition. The scores of the trait-aggressive subjects, tested in a before-after analysis, showed an increase in their hostility level. Fantasy capacity did not influence the scores. 相似文献

Adult attachment style has consequences for mental health, interpersonal functioning and emotion regulation. This occurs partly deliberately, also referred to as explicit, and partly on an automatic level outside of conscious awareness, also referred to as implicit. Whereas explicit adult attachment can be assessed with self-report instruments, measurement of implicit adult attachment requires indirect methods. This paper describes the psychometric properties of two Implicit Association Tests measuring general adult attachment in a population sample. The study evaluated the reliability and the validity of the Avoidant Attachment IAT (ANX-IAT) and the Anxious Attachment IAT (AVOID-IAT). Validity was evaluated against self-report measures of adult attachment style (RQ), psychopathology (SQ-48), and well-being (MHC-SF). The split-half reliabilities of both IATs were good; the test-retest reliability of the ANX-IAT was adequate; however the AVOID-IAT had low test-retest reliability. Both IATs did not explain variance in psychopathology additional to explicit measures. The AVOID-IAT showed added value over explicit measurement of avoidant attachment in explaining variance in well-being, particularly regarding emotional and psychological well-being. The ANX-IAT did not explain variance in any measure of well-being additional to the explicit measure of anxious attachment. Our findings provide a basis from which more valid IATs measuring general adult attachment can be developed. Furthermore, they suggest that implicit avoidant attachment might be related to well-being, particularly emotional and psychological well-being. However, further research is needed to investigate the role of implicit general adult attachment in mental health and to optimize the two IATs in terms of validity before clinical use is recommended. 相似文献

The gateway sign configuration has been effective at increasing motorist yielding and reducing speeds at crosswalks. A gateway configuration uses in-street signs at a crosswalk on each edge of the roadway and on each lane line. Although this intervention is effective at increasing motorist yielding at uncontrolled crosswalks, the limits of the intervention have yet to be tested. The present study examined if 1) the effects of the gateway intervention on one crosswalk would generalize to an untreated adjacent crosswalk, and 2) if the effects of an offset configuration of signs which partially treated each crosswalk could maximize the effects of that generalization. Experiment 1 showed that less yielding occurred at the untreated crosswalk than at the treated crosswalk, though yielding was higher than baseline. In Experiment 2, results showed that an offset gateway configuration could produce comparable levels of yielding at both crosswalks. 相似文献

Lists of thematically related words were presented to participants with or without a concurrent task. In Experiments 1 and 2, respectively, English or Spanish word lists were either low or high in concreteness (concrete vs abstract words) and were presented, respectively, auditorily or visually for study. The addition of a concurrent visual or auditory task, respectively, substantially reduced correct recall and doubled the frequency of false memory reports (nonstudied critical or theme words). Divided attention was interpreted as having reduced the opportunity for participants to monitor successfully their elicitations of critical associates. Comparisons of concrete and abstract lists revealed significantly more recalls of false memories for abstract than concrete word lists. Comparisons between two levels of attention, two levels of word concreteness, and two presentation modalities failed to support the "more is less" effect by which enhanced correct recall is accompanied by increased frequencies of false memories. 相似文献

This study served to replicate and extend our previously obtained hierarchical model of the relationships among general anxiety vulnerabilities, specific anxiety vulnerabilities and specific anxiety manifestations including panic symptoms, health anxiety, obsessive-compulsive symptoms and worry. Questionnaires assessing these variables, as well as positive affectivity and depressiveness, were administered to 125 outpatients seeking treatment for panic disorder, social anxiety disorder, obsessive-compulsive disorder, generalized anxiety disorder or major depressive disorder. The results, using a clinical sample, were highly consistent with the hierarchical model obtained in the previous study using a student sample. A more elaborate model, based on published theoretical and empirical evidence, was identified and tested, and similar results were obtained. Negative affectivity had expected direct positive effects on all of the specific anxiety and depression manifestations, with the exception of health anxiety, which showed a negative relationship, and OCD symptoms, which showed no relationship. Positive affectivity was found to be a specific risk factor for depression, while intolerance of uncertainty was found to be a specific risk factor for worry and depression. Finally, anxiety sensitivity appears to be a significant risk factor for panic and health anxiety. 相似文献

The effects of a symbolic "yield here to pedestrians" sign and advance yield pavement markings on pedestrian/motor vehicle conflicts, motorists' yielding behavior, and the distance motorists' yield in advance of crosswalks were evaluated at multilane crosswalks at uncontrolled T intersections. In Experiment 1, the sign, when used alone, reduced pedestrian/motor vehicle conflicts and increased motorist yielding distance. The use of fluorescent yellow-green sheeting as the background of the sign did not increase the effectiveness of the sign. Further reductions in pedestrian/motor vehicle conflicts and further increases in yielding distance were associated with the addition of advance yield pavement markings. In Experiment 2, advance yield pavement markings, when used alone, were as effective in reducing pedestrian/motor vehicle conflicts and increasing yielding distance as the sign combined with pavement markings. These data suggest that the pavement markings were the essential component for reducing conflicts and increasing yielding distance. 相似文献

The authors suggest that decisions made from multiple pieces of evidence are performed hy mechanisms of parallel constraint satisfaction, which are related to cognitive consistency theories. Such reasoning processes are bidirectional--decisions follow from evidence, and evaluations of the evidence shift toward coherence with the emerging decision. Using a factually complex legal case, the authors observed patterns of coherence shifts that persisted even when the distribution of decisions was manipulated (Study 1) and influenced by the participants' attitudes (Study 2). The evaluations of the evidence cohered with the preferred decision even when participants changed their preference (Study 3). Supporting the bidirectionality of reasoning. Study 4 showed that assigning participants to a verdict affected their evaluation of the evidence. Coherence shifts were observed also in related background knowledge. This research suggests that cognitive consistency theories should play a greater role in the understanding of human reasoning and decision making. 相似文献

Verb production is notoriously difficult for individuals with Broca's aphasia, both at the word and at the sentence level. An intriguing question is at which level in the speech production these problems arise. The aim of the present study is to identify the functional locus of the impairment that results in verb production deficits in Broca's aphasia. Levelt's (1989) model is used as a theoretical framework for this study. Two experiments have been conducted, one on verb movement and one on verbs with alternating transitivity. The results suggest that the functional impairment in Broca's aphasia should be located in Levelt's "grammatical encoder." 相似文献
