The time-based resource-sharing model of working memory assumes that memory traces suffer from a time-related decay when attention is occupied by concurrent activities. Using complex continuous span tasks in which temporal parameters are carefully controlled, P. Barrouillet, S. Bernardin, S. Portrat, E. Vergauwe, & V. Camos (2007) recently provided evidence that any increase in time of the processing component of these tasks results in lower recall performance. However, K. Oberauer and R. Kliegl (2006) pointed out that, in this paradigm, increased processing times are accompanied by a corollary decrease of the remaining time during which attention is available to refresh memory traces. As a consequence, the main determinant of recall performance in complex span tasks would not be the duration of attentional capture inducing time-related decay, as Barrouillet et al. (2007) claimed, but the time available to repair memory traces, and thus would be compatible with an interference account of forgetting. The authors demonstrate here that even when the time available to refresh memory traces is kept constant, increasing the processing time still results in poorer recall, confirming that time-related decay is the source of forgetting within working memory. 相似文献

Younger and older adults performed an inequality verification task (7+6 < 15, Yes/No?) in a control condition and in a dual-task condition where they simultaneously performed an executive-component task. Arithmetic-problem characteristics were manipulated in order to test strategy selection (i.e., choice of appropriate strategies in order to improve performance) and strategy execution (i.e., performance of the cognitive processes involved in each strategy). Results revealed that strategy selection changes with age: Older adults mainly selected one type of strategies in contrast to younger adults who used several types of strategies. These age-related changes were similar in the control and dual-task conditions. Strategy execution also changed with age, as shown by larger age-related differences on hardest problems. These age-related changes were larger in the dual-task condition, compared to the control condition. This impact of executive components as mediator of age-related changes depended on general age-related slowing. We discuss these findings in order to further understand the effects of age on arithmetic performance. 相似文献

Cognitive and linguistic skills in Swedish children with cochlear implants - measures of accuracy and latency as indicators of development 总被引:1,自引:1,他引:0

The purpose of the present study was to examine working memory (WM) capacity, lexical access and phonological skills in 19 children with cochlear implants (CI) (5;7-13;4 years of age) attending grades 0-2, 4, 5 and 6 and to compare their performance with 56 children with normal hearing. Their performance was also studied in relation to demographic factors. The findings indicate that children with CI had visuospatial WM capacities equivalent to the comparison group. They had lower performance levels on most of the other cognitive tests. Significant differences between the groups were not found in all grades and a number of children with CI performed within 1 SD of the mean of their respective grade-matched comparison group on most of the cognitive measures. The differences between the groups were particularly prominent in tasks of phonological WM. The results are discussed with respect to the effects of cochlear implants on cognitive development. 相似文献

This study examined to what extent bullying behavior of popular adolescents is responsible for whether bullying is more or
less likely to be accepted or rejected by peers (popularity-norm effect) rather than the behavior of all peers (class norm).
Specifically, the mean level of bullying by the whole class (class norm) was split into behavior of popular adolescents (popularity-norm)
and behavior of non-popular adolescents (non-popularity-norm), and examined in its interaction with individual bullying on
peer acceptance and peer rejection. The data stem from a peer-nominations subsample of TRAILS, a large population-based sample
of adolescent boys and girls (N = 3312). The findings of multilevel regression analyses demonstrated that the negative impact of individual bullying on peer
acceptance and the positive impact on peer rejection were particularly weakened by bullying by popular adolescents. These
results place the class-norm effects found in previous person-group dissimilarity studies in a different light, suggesting
that particularly bullying by popular adolescents is related to the social status attached to bullying.

This study investigated the effect of thin images according to two dimensions of body-image (BI) investment. Ninety-five females were classified as high or low investors based on the Appearance Schemas Inventory-Revised Self-Evaluative Salience (SES) and Motivational Salience (MS) subscales. Participants viewed advertisements portraying either the thin ideal or products. Results indicated that both women high in SES and MS reported lowered appearance self-esteem but greater BI importance following thin exposures. However, only the high SES group reported greater BI dissatisfaction and importance of current-ideal discrepancies after seeing thin images. Although highly invested women (regardless of their motivation for investment) are more responsive to thin media images than are women low in investment, those invested for self-definition are affected on more dimensions than are those invested for appearance management. 相似文献

In the 2-4-6 rule discovery task, reasoners seek to discover a rule that governs the arrangement of three numbers (or triple). The to-be-discovered rule is “ascending numbers”. Upon being given the triple 2-4-6 as an initial example, however, reasoners tend to formulate algebraically specific hypotheses. Traditionally, this task is conducted primarily from an internal representation of the triples and candidate hypotheses. More recently, substantial representational effects have been demonstrated wherein an external representation of the dimensions of the problem space facilitated successful rule discovery. In the two experiments reported here, an interactive graphical representation was created by concurrently plotting each triple produced by the participants. In Experiment 1, participants who performed the task with this external representation were more likely to discover the rule than were a group of control participants. Experiment 2 replicated the effect but also assessed participants' hypotheses for each triple generated. Results indicated that a graphical representation of the triples fostered the development of hypotheses that were less constrained by the implied algebraic specificity of the initial triple. 相似文献

Relational reasoning (A > B, B > C, therefore A > C) shares a number of similarities with numerical cognition, including a common behavioural signature, the symbolic distance effect. Just as reaction times for evaluating relational conclusions decrease as the distance between two ordered objects increases, people need less time to compare two numbers when they are distant (e.g., 2 and 8) than when they are close (e.g., 3 and 4). Given that some remain doubtful about such analogical representations in relational reasoning, we determine whether numerical cognition and relational reasoning have other overlapping behavioural effects. Here, using relational reasoning problems that require the alignment of six items, we provide evidence showing that the subjects' linear mental representation affects motor performance when evaluating conclusions. Items accessible from the left part of a linear representation are evaluated faster when the response is made by the left, rather than the right, hand and the reverse is observed for items accessible from the right part of the linear representation. This effect, observed with the prepositions to the left of and to the right of as well as with above and below, is analogous to the SNARC (Spatial Numerical Association of Response Codes) effect, which is characterized by an interaction between magnitude of numbers and side of response. 相似文献

Health-related quality of life (QoL) is reduced in patients with recurrent vasovagal (VVS) or unexplained (US) syncope. Little
is known regarding these patients’ QoL as pertains to their capacity to attain their life goals. Factors influencing QoL,
such as sex, syncope type and illness representations have not been studied. Our objective is to examine the relationship
between illness representations and QoL, as well as possible sex and syncope type differences. One hundred and four patients
undergoing tilt-table testing (TTT) for recurrent syncope were interviewed one month before TTT, using questionnaires. Data
were analysed using ANCOVAs, a-priori Helmert contrasts for illness representations, and regressions. Patients with US had
a poor QoL compared to those with VVS [F(1, 91) = 10.46; p < 0.01], particularly in men (p < 0.01). Patients with higher perceived syncope severity showed an impoverished QoL relative to those with less severe perceptions
[F(1, 91) = 5.47; p < 0.05]. A hierarchical regression revealed that illness representations mediate the impact of lifetime number of syncope
on QoL. In conclusion, QoL is reduced in these patients, and is influenced by illness representations. Helping patients change their
perceptions about their syncope may be an efficient way to promote QoL. 相似文献

In this reply, three core notions from Schürmann’s comment The materiality of the abstraction “voice” are picked out and discussed: the ethos, the so called trialogical self and vocality as principle. The notion of ethos is explored through the word’s history, coming to say that ethos develops in relation to a certain geographical place and is determined by the social practices of a historically situated community. Thus, the concept allows to see how current scientific activities are rooted in reality, taken in the socio-cultural sense. The “trialogical self” is discussed in its implications, leading to firmly retain “dialogical self” as sign of a movement leading through the other to self. Schürmann’s distinction of voice as phenomenon and vocality as principle is seen as fruitful supplement to own ideas, especially as it highlights the fact that it is the act of uttering in different modes which matters for a language notion based in addressivity. 相似文献

From 1957 through the mid-1970s, John Bowlby, one of the founders of attachment theory, was in close personal and scientific
contact with Harry Harlow. In constructing his new theory on the nature of the bond between children and their caregivers,
Bowlby profited highly from Harlow’s experimental work with rhesus monkeys. Harlow in his turn was influenced and inspired
by Bowlby’s new thinking. On the basis of the correspondence between Harlow and Bowlby, their mutual participation in scientific
meetings, archival materials, and an analysis of their scholarly writings, both the personal relationship between John Bowlby
and Harry Harlow and the cross-fertilization of their work are described.
Frank C.P. van der Horst is a PhD student and Lecturer at the Centre for Child and Family Studies at Leiden University, The Netherlands. The work presented in this special issue is part of his doctoral thesis on the roots of Bowlby’s attachment theory. The defence of this thesis, titled John Bowlby and ethology: a study of cross-fertilization, is scheduled for early 2009. Helen A. LeRoy recently retired from the Harlow Primate Lab at the University of Wisconsin-Madison after working there for nearly half a century. During that time, she worked closely with Harry Harlow from her arrival in 1958 until his retirement in 1974. She was Harlow’s executive assistant and was his help and stay in the editing of the Journal of Comparative and Physiological Psychology. René van der Veer is Professor of History of Educational Thinking at Leiden University, The Netherlands. His research addresses the work of key educational thinkers such as Gal’perin, Janet, Piaget, Vygotsky, Werner, and Wallon. In a longer study the origin of the idea of the social mind was traced. He is on the Editorial Board of Integrative Psychological and Behavioral Sciences. 相似文献
