In two experiments, the peak-interval procedure was used with humans to test effects related to gaps in multisecond timing. In Experiment 1, peak times of response distributions were shorter when the gap occurred later during the encoding of the criterion time to be reproduced, suggesting that gap expectancy shortened perceived durations. Peak times were also positively related to objective target durations. Spreads of response distributions were generally related to estimated durations. In Experiment 2, peak times were shortest when gaps were expected but did not occur, confirming that the shortening effect of gap expectancy is independent of the gap occurrence. High positive start-stop correlations and moderate positive peak-time-spread correlations showed strong memory variability, whereas low and negative start-spread correlations suggest small response-threshold variability. Correlations seemed not to be influenced by expectancy. Overall, the peak-interval procedure with gaps provided relevant information on similarities and differences in timing in humans and other animals. 相似文献

Here we reprint, and provide background and a commentary on, a recently-rediscovered lecture by Godfrey H. Thomson entitled, “Intelligence and civilisation.” It was delivered at the University of Manchester, UK, on 23rd October, 1936, printed in 1937 in the short-lived Journal of the University of Manchester and as a pamphlet in Edinburgh. It was one in the series of lectures supported by the industrialist and philanthropist Ludwig Mond. The lecture is unusually valuable in that it places the theory, testing and practical application of intelligence against the background of the rise of fascism and its threat to civilisation. The lecture is a candid and accessible ‘confession and contemplation'; the frank thoughts of a person committed to, but critical of, intelligence testing and theory, but convinced of the power and place of intelligence differences in people's lives and in civilisation. It comes at an important time for Thomson, with regard to three of his major achievements: his Moray House Test series, the Scottish Mental Survey of 1932 (and the Northumbrian testing exercise that preceded it), and the preparation of his book The Factorial Analysis of Human Ability. The understanding of the lecture is enhanced by recently-discovered archive materials on Thomson and his circle. ([Thomson, G.H. (1937a). Intelligence and civilisation: A Ludwig Mond lecture delivered at the University of Manchester on October 23rd, 1936.

This paper examines the role of self-interest and symbolic attitudes as predictors of support for two domestic policy issues—guaranteed jobs and incomes and national health insurance—in the American National Election Survey (ANES) between 1972 and 2004. As was the case in 1976 when Sears, Lau, Tyler, and Allen (1980 ) first explored this topic, symbolic attitudes continue to be much more important predictors of policy attitudes than various indicators of self-interest over the 30 years we analyze. We explore this finding further to determine whether any individual/internal and external/contextual variables affect the magnitude of self-interest effects on policy support. Five possible internal moderators of self-interest effects are examined: (1) political knowledge, (2) issue publics, (3) political values, (4) social identifications, and (5) emotions, but none are found to boost the magnitude of the self-interest effect. However, we do find some evidence that contextual variables representing the social/information environment moderate the impact of self-interest on public opinion. 相似文献

Background Prior studies outside of the UK have shown that peer victimization is negatively associated with school adjustment. Aims To examine concurrent and short‐term longitudinal associations between peer victimization (physical, malicious teasing, deliberate social exclusion, and malicious gossiping) and two measures of school adjustment (school liking and recess liking), and test if these associations were moderated by year and sex. Sample A UK sample of 429 pupils in Years 4, 5, and 6 (Grades 3, 4, and 5, respectively, in USA) participated in the Autumn/Winter (Time 1) and 189 of these provided follow‐up data during the Spring/Summer (Time 2) of the same school year. Method Peer nominations of victimization, and self‐reports of school adjustment were collected in individual and small group interviews. Results At time 2 (but not Time 1), victimization predicted concurrent school liking among year 6 pupils but not among year 4/5 pupils, and victimization predicted recess liking among all pupils. Victimization also predicted changes in School liking among boys (not girls) and among Year 6 (not Year 4/5) pupils, and victimization predicted changes in recess liking among all pupils. Conclusions The associations between victimization and poor school adjustment found elsewhere were replicated with this British sample. The implications of these results for children's social adjustment at school were discussed. 相似文献

Recent work has demonstrated that horizontal saccadic eye movements enhance verbal episodic memory retrieval, particularly in strongly right-handed individuals. The present experiments test three primary assumptions derived from this research. First, horizontal eye movements should facilitate episodic memory for both verbal and non-verbal information. Second, the benefits of horizontal eye movements should only be seen when they immediately precede tasks that demand right and left-hemisphere processing towards successful performance. Third, the benefits of horizontal eye movements should be most pronounced in the strongly right-handed. Two experiments confirmed these hypotheses: horizontal eye movements increased recognition sensitivity and decreased response times during a spatial memory test relative to both vertical eye movements and fixation. These effects were only seen when horizontal eye movements preceded episodic memory retrieval, and not when they preceded encoding (Experiment 1). Further, when eye movements preceded retrieval, they were only beneficial with recognition tests demanding a high degree of right and left-hemisphere activity (Experiment 2). In both experiments the beneficial effects of horizontal eye movements were greatest for strongly right-handed individuals. These results support recent work suggesting increased interhemispheric brain activity induced by bilateral horizontal eye movements, and extend this literature to the encoding and retrieval of landmark shape and location information. 相似文献

The current experiments examine mental health clinicians' beliefs about biological, psychological, and environmental bases of the DSM-IV-TR mental disorders and the consequences of those causal beliefs for judging treatment effectiveness. Study 1 found a large negative correlation between clinicians' beliefs about biological bases and environmental/psychological bases, suggesting that clinicians conceptualize mental disorders along a single continuum spanning from highly biological disorders (e.g., autistic disorder) to highly nonbiological disorders (e.g., adjustment disorders). Study 2 replicated this finding by having clinicians list what they thought were the specific causes of nine familiar mental disorders and rate their bio–psycho–environmental bases. Study 3 further found that clinicians believe medication to be more effective for biologically based mental disorders and psychotherapy to be more effective for psychosocially based mental disorders. These results demonstrate that even expert mental health clinicians make strong distinctions between psychological and biological phenomena. 相似文献

Can we build endogenous expectations about the locus of occurrence of a target without being able to describe them? Participants performed cue-target detection tasks with different proportions of valid and invalid trials, without being informed of these proportions, and demonstrated typical endogenous effects. About half were subsequently able to correctly describe the cue-target relationships ('verbalizers'). However, even non-verbalizer participants showed endogenous orienting with peripheral cues (Experiments 1 and 3), not depending solely on practice (Experiment 2). Explicit instructions did not bring about dramatic advantages in performance (Experiment 4). With central symbolic cues, only verbalizers showed reliable endogenous effects (Experiment 5). We concluded that endogenous orienting with peripheral cues can occur independently of participants developing explicit hypotheses about the cue-target relationships. 相似文献

Some individuals with superior memory, such as the mnemonist Shereshevskii (Luria, 1968), are known to have synaesthesia. However, the extent to which superior memory is a general characteristic of synaesthesia is unknown, as is the precise cognitive mechanism by which synaesthesia affects memory. This study demonstrates that synaesthetes tend to report subjectively better than average memory and that these reports are borne out with objective testing. Synaesthetes experiencing colours for words show better memory than matched controls for stimuli that induce synaesthesia (word lists) relative to stimuli that do not (an abstract figure). However, memory advantages are not limited to material that elicits synaesthesia because synaesthetes demonstrate enhanced memory for colour per se (which does not induce a synaesthetic response). Our results suggest that the memory enhancement found in synaesthetes is related to an enhanced retention of colour in both synaesthetic and nonsynaesthetic situations. Furthermore, this may account for the fact that synaesthetic associations, once formed, remain highly consistent. 相似文献

In previous semantic-illusion research the tacit assumption has been that questions and statements-to-be-verified of similar semantic content lead to a similar proportion of semantic illusions. This assumption was made despite the fact that questions are thought to have different processing demands from those of statements. This paper presents empirical evidence that questions tend to lead to more semantic illusions than do statements-to-be-verified. Two experiments were carried out to provide a direct comparison between the semantic-illusion rates for statements and for questions. In Experiment 1, open-ended questions led to significantly more semantic illusions than did true/false statements. Experiment 2 replicated this effect using multiple-choice response options in the question condition. It is concluded that the syntactic form of a sentence affects the way in which semantic information is processed, and the implications of the findings are discussed. 相似文献
