Using an arithmetic-based retrieval-induced forgetting (RIF) paradigm, researchers have found evidence that participants with very high arithmetic proficiency (Chinese adults), but not less-skilled participants (Canadian adults), solved some simple additions (e.g. 3 + 2) using fast procedural skills. Here we sought converging evidence for this using the operator-priming paradigm. Previous research testing simple addition and multiplication found that a 150-ms preview of the operator (+ or ×) facilitated only addition performance. This was taken as evidence that addition, but not multiplication, was solved by procedural algorithms that could be primed by presentation of the plus sign. In the present study, Chinese and Canadian adults (N = 144) were tested in the operator-priming paradigm but, in contrast to the RIF results, there was little evidence that operator-priming effects differed between the groups and robust operator priming was observed in both addition and multiplication. Thus, the operator preview results did not reinforce the results of previous research but the experiment revealed robust group differences in operand preview effects: For the Chinese, but not the Canadians, a preview of the numerical operands produced much greater facilitation for multiplication than addition. The fact that CN obtained a mean 103-ms gain for multiplication from the 150-ms preview of the operands strongly suggests that multiplication was their default operation in this paradigm. This result adds a potentially important new phenomenon to the behavioural distinctions between Chinese and North American adults' arithmetic skills. 相似文献

The concern about man's harmful impact on the environment focuses attention on the external environment, i.e., the real world out there, which may not survive in a form to support life. But supporting life of an individual is in the hands of that individual's brain, which is primarily concerned with various needs of the internal environment, also referred to as the self. Confronted with diverse and often competing needs, the brain has evolved a complexity in man, which makes it doubtful that any one collective strategy may be effective in preserving the external environment. 相似文献

The purpose of this paper was to investigate how individual differences in glance strategy could impact the glance performance test defined in the NHTSA visual manual distraction guidelines. Better understanding of the test procedure could help development of new technology for safe driving. A custom in-vehicle information system was developed and assessed in a driving simulator by eighteen participants. The interfaces were designed according to recommendations in the NHTSA guidelines and contained manual radio-tuning tasks, sound settings tasks and six letter spelling tasks. Two of the six tested interfaces fully complied with the test. In addition, clear individual differences in glance strategy were found among the participants. Four individual glance strategies were identified. Two of these, long glancers and frequent glancers, highly affected the outcome of the compliance test. Participants belonging to the long glancers and the frequent glancers categories were identified as statistical outliers in many test cases. For example, if the individual values of these participants were replaced with sample mean, the number of complying interfaces would increase to five out of six, which is more in line with expectations for these interfaces. The results of this study show that individual variations in glance strategy exist. Also, these individual variations seem to have a non- negligible influence on the result when performance-testing of in-vehicle interfaces is done according to the NTHSA guidelines. 相似文献

Our contribution aims to verify whether parental knowledge about child development and parenting constitutes a protective factor in the application of dysfunctional educational practices. Numerous studies have found that parental knowledge has a great influence on parenting, however it remains unclear whether both are casually linked in a direct and linear way. Data currently available on parental knowledge almost exclusively refers to mothers and subjects at risk. Furthermore, there are almost no studies which take into consideration subjects who are Italian citizens.In contrast our work takes into consideration a normative sample of 157 Italian couples who are the parents of children aged between 16 and 36 months and who completed the Knowledge of Infant Development Inventory (KIDI; MacPhee, 1981) and the Parenting Scale (Arnold, O’Leary, Wolff, & Acker, 1993). The results highlight differences between mothers and fathers, both in terms of knowledge levels (higher for mothers) and educational practices (maternal practices are more frequently dysfunctional); knowledge influences educational practices above all in the case of fathers, although said effect is slight, which supports the idea that interaction between knowledge and parental practices is not linear but rather mediated by other factors. 相似文献

Affective forecasting often drives decision-making. Although affective forecasting research has often focused on identifying sources of error at the event level, the present investigation draws upon the “realistic paradigm” in seeking to identify factors that similarly influence predicted and actual emotions, explaining their concordance across individuals. We hypothesised that the personality traits neuroticism and extraversion would account for variation in both predicted and actual emotional reactions to a wide array of stimuli and events (football games, an election, Valentine's Day, birthdays, happy/sad film clips, and an intrusive interview). As hypothesised, individuals who were more introverted and neurotic anticipated, correctly, that they would experience relatively more unpleasant emotional reactions, and those who were more extraverted and less neurotic anticipated, correctly, that they would experience relatively more pleasant emotional reactions. Personality explained 30% of the concordance between predicted and actual emotional reactions. Findings suggest three purported personality processes implicated in affective forecasting, highlight the importance of individual-differences research in this domain, and call for more research on realistic affective forecasts. 相似文献

Individuals with agrammatic Broca's aphasia experience difficulty when processing reversible non‐canonical sentences. Different accounts have been proposed to explain this phenomenon. The Trace Deletion account (Grodzinsky, 1995, 2000, 2006) attributes this deficit to an impairment in syntactic representations, whereas others (e.g., Caplan, Waters, Dede, Michaud, & Reddy, 2007; Haarmann, Just, & Carpenter, 1997) propose that the underlying structural representations are unimpaired, but sentence comprehension is affected by processing deficits, such as slow lexical activation, reduction in memory resources, slowed processing and/or intermittent deficiency, among others. We test the claims of two processing accounts, slowed processing and intermittent deficiency, and two versions of the Trace Deletion Hypothesis (TDH), in a computational framework for sentence processing (Lewis & Vasishth, 2005) implemented in ACT‐R (Anderson, Byrne, Douglass, Lebiere, & Qin, 2004). The assumption of slowed processing is operationalized as slow procedural memory, so that each processing action is performed slower than normal, and intermittent deficiency as extra noise in the procedural memory, so that the parsing steps are more noisy than normal. We operationalize the TDH as an absence of trace information in the parse tree. To test the predictions of the models implementing these theories, we use the data from a German sentence—picture matching study reported in Hanne, Sekerina, Vasishth, Burchert, and De Bleser (2011). The data consist of offline (sentence‐picture matching accuracies and response times) and online (eye fixation proportions) measures. From among the models considered, the model assuming that both slowed processing and intermittent deficiency are present emerges as the best model of sentence processing difficulty in aphasia. The modeling of individual differences suggests that, if we assume that patients have both slowed processing and intermittent deficiency, they have them in differing degrees. 相似文献

Li and Baroody present a study in which they investigate toddlers’ spontaneous attention to exact quantity without acknowledging how previous studies of spontaneous focusing on numerosity (SFON) are related to their concept and methods. In this commentary requested by the European Journal of Developmental Psychology, we argue that the concept and the methods of spontaneous attention to exact quantity in the study of Li and Baroody clearly arise from previous research on SFON, as the authors have previously noted in their paper published in 2008. It is highly questionable whether their approach can be theoretically or methodologically dissociated from the previous research on SFON tendency to the extent that it is necessary to use an alternative name for the concept in their study. 相似文献

The remarkable cognitive abilities of bats indicate that they may recognise particular conspecifics. Because of their highly developed auditory system, it is obvious that vocalisations of bats may give information about the individual emitting them. In a field study of the social behaviour in the Indian false vampire bat (Megaderma lyra), two different types of vocalisation were recorded and analysed. The bats emitted these vocalisations only while aggregating with conspecifics inside the day roost. The “landing strophe” consisted of a number of brief multiharmonic downward frequency-modulated (FMdown) sounds which levelled off as a constant frequency (CF), and the “clatter strophe” was composed of a number of multiharmonic FMdown sounds which became shallow at the end as a short CF. The sounds of the landing strophe and the ¶clatter strophe differed in repetition rate, duration, harmonic components and frequency. Time pattern and peak frequency of the two sound types differed highly significantly between single, unidentified bats. The sounds were inter-individually distinct when the three parameters were combined as an acoustical space. Therefore, these vocalisations might be used for individual recognition in adult bats. 相似文献
