In this study, ROC and z-ROC parameters are applied in word recognition memory, with words classified according to frequency and class. In doing so, unbiased techniques can be used to assess hits and false alarms and to obtain standardized distributions for each experimental condition. Our results confirm the existence of differences in word recognition memory for experimental exposition time, type of words and other pre-experimental effects. These data are consistent with familiarity and recollection models when words' frequency is used, and with familiarity, recollection and dual-route models when words are organized according to class. Finally, we argue in favour of an interactive processing model (words organized according to frequency) versus a processing model nearer to modularity (words organized according to class). 相似文献

Concerns have been raised about the ability of diagnostic criteria for attention-deficit/hyperactivity disorder (ADHD) to distinguish subtypes that are clearly distinct from each other with regard to clinical correlates. One area of concern is that research regarding differences in anxiety and depression as a function of ADHD subtype has produced discrepant findings. This study was designed to systematically evaluate whether the ADHD subtypes differ with regard to level of internalizing symptoms. From a large pool of children referred to an ADHD center based in a pediatric hospital, children were differentiated into three groups: ADHD, Combined Type (ADHD/COM); ADHD, Inattentive Type (ADHD/I); and a non-ADHD, comparison group (COMP). Parent- and child-report measures using both dimensional and categorical methods were used to assess internalizing symptoms. The results indicated that children with ADHD/COM and ADHD/I had similar levels of anxiety and depression. Subtype differences related to parent-reported depression were accounted for by group differences in level of externalizing problems. The results were discussed with regard to their implications for refining the criteria used to differentiate children with ADHD into subtypes. 相似文献

The earliest phases of the mother-infant relationship may markedly be influenced, for better or worse, by the emotional availability of the father. In our contemporary Western societies young expectant couples are often isolated psychologically. It is suggested that if such circumstances exist and the mother also has psychological risk factors stemming from her past history and/or from her experience with the pregnancy and delivery, the husband's ability to fulfill some special mothering functions toward his wife would tip the balance between adequate coping or manifest disturbance in the mother—infant relationship. 相似文献

Twins' marriages to non‐twins yield genetically and socially informative kinships. Monozygotic (MZ) twins' genetic identity makes them ‘genetic parents’ of their nieces/nephews, and their nieces/nephews their ‘genetic children’. The present study is the first to apply twin‐family models to study social relatedness. Analyses of twin families (MZ: N = 248; DZ: N = 75) tested evolutionary‐based concepts concerning social closeness, perceived similarity and caretaking. Hypotheses based on Hamilton's inclusive fitness theory were supported: MZ twin aunts/uncles expressed greater social closeness towards their nieces/nephews than DZ twin aunts/uncles; and female twins from same‐sex pairs expressed greater closeness towards their nieces/nephews than male twins from same‐sex pairs. This study underlines benefits of associations between behavioural‐genetic and evolutionary psychological theories, methods and interpretations. Copyright © 2007 John Wiley & Sons, Ltd. 相似文献

Exposure to a repeating set of target strings generated by an artificial grammar in a speeded matching task generates both explicit and implicit knowledge. Previous research has shown that implicit knowledge (assessed via a priming measure) is preserved after a retention interval of one week but explicit knowledge (assessed via recognition) is significantly reduced. In two experiments, we replicated and extended Tunney's findings. Experiment 1 was a partial replication of the experiment conducted by Tunney, and demonstrated that the decline in recognition shown by Tunney was not due to a repetition of test items at the pre and post times of assessment. In addition, Experiment 1 lends credibility to Tunney's assumption that recognition scores assess explicit rather than implicit knowledge. Experiment 2 extended Tunney's findings theoretically by demonstrating that interference can produce the pattern of findings demonstrated in the present Experiment 1 as well as in Tunney. 相似文献

This study examines women’s representation in Spanish national online newspapers. For this purpose, we developed an automatic content analysis method to analyze an extensive sample of 34,235 news articles gathered from March to May 2006. Our general objective was to investigate possible gender bias in Spanish online news. To do so we focused on three journalistic routines, one at the individual level of the reporter (gender) and two at the media routine level (sections, publication day, and article length). The results of the estimated multivariate models revealed that women are still linked to traditionally “female” sections, such as people, society, and culture. Analysis of article length and publication day showed that women appear more frequently in shorter news items and in the Sunday news, which we interpreted as indicators of male association with newsworthiness. We also found differences in gender reporting since female journalists tend to include more women in the news they report than their male peers. These results provide evidence that online newspapers continue to perpetuate underrepresentation, stereotyping, and discrimination of women in web news thereby reinforcing gender inequality. 相似文献

Aggressive interactions between animals often occur in the presence of third parties. By observing aggressive signalling interactions, bystanders may eavesdrop and gain relevant information about conspecifics without the costs of interacting. On the other hand, interactants may also adjust their behaviour when an audience is present. This study aimed to test how knowledge about fighting ability of an audience affects aggressive interactions in male Siamese fighting fish. Subjects were positioned between two dyads of non-interacting males and allowed to observe both dyads shortly before the view to one of the dyads was blocked, and the dyads were allowed to interact. Subjects were subsequently exposed to an unknown opponent in the presence of either the winner or the loser of the seen or unseen interaction. The results suggest a complex role of the characteristic of an audience in the agonistic behaviours of a subject engaged in an interaction. The presence of a seen audience elicited more aggressive displays towards the opponent if the audience was a loser. This response was different in the presence of an unseen audience. Subjects then directed a higher aggressiveness against their opponent if the audience was a winner. These results also suggest a potentially more complex and interesting process allowing individuals to gain information about the quality and threat level of an unknown audience while it is interacting with a third party. The importance of information acquisition for an individual to adapt its behaviour and the role of communication networks in shaping social interactions are discussed. 相似文献
