Effects of Tradislexia videogame on phonological awareness and word recognition in dyslexic children
The purpose of this research was to analyze the effects of multimedia training on phonological awareness and word recognition in dyslexic children. We used a control pretest-posttest design, and a sample of 62 children (26 male, 36 female) was selected from Primary Education. Children were selected and classified into two different groups: (1) an experimental group (N=32), and (2) a control group (N=30). The average range age was 9 and 12 years (M=126.7, SD=11.7). We administered phonological awareness tasks, which include different types of syllabic structure from the Sicole-R Multimedia Battery for assessment of cognitive processes in reading. We analyzed whether the Tradislexia videogame affected phonological awareness, considering separately the complexity of syllable structure and type of phonological awareness task. We also analyzed whether the gains in phonological processes were related to training based on type of task or type of syllable structure. The results showed that when we controlled the position of phoneme, the multimedia treatment in segmentation and blending with words that include CV syllables is a better predictor to explain improvement of word decoding processes. 相似文献

The Clock Drawing Test (CDT) is a widely used instrument in the neuropsychological assessment of Alzheimer's disease (AD). As CDT performance necessitates several cognitive functions (e.g., visuospatial and constructional abilities, executive functioning), an interaction of multiple brain regions is likely. Fifty-one subjects with mild cognitive impairment, 23 with AD and 15 healthy controls underwent high-resolution magnetic resonance imaging. Optimized voxel-based morphometry (VBM) was performed to investigate the putative association between CDT performance and gray matter (GM) density throughout the entire brain. In the first step of analysis (p<.001, uncorrected), VBM revealed a reduced GM density in numerous cortical (temporal lobe, frontal lobe, parietal lobe, cerebellum) and subcortical (thalamus, basal ganglia) brain regions to be associated with poorer CDT performance. When corrected for multiple comparisons (p<.01), the associations remained significant predominantly in the left temporal and--less pronounced--the right temporal lobe. VBM demonstrated CDT performance to depend on the integrity of widely distributed cortical and subcortical areas in both brain hemispheres with accentuation in the left-sided temporal lobe region. 相似文献

The study of prospective memory (ProM), the remembering of the delayed execution of intentions, has been growing in recent years, and we know quite a bit about the cognitive variables that affect it. But the performance of a task depends on personality variables as well as on cognitive ones, and the role of personality variables in ProM has only been partially studied, the results being less conclusive. We sought to address two main objectives: (1) to quantify the joint influence of cognitive and personality variables on three ProM tasks in the laboratory (two based on events and the other on time), and (2) to identify the personality profiles of those who perform well in these three ProM tasks as opposed to those who do not. The cognitive and personality variables were evaluated with two sessions of 157 participants. The 16 PF-5 was applied (Cattell, Cattell & Cattell, 1993) and other cognitive variables were measured. With the data obtained, we ran several regression analyses to determine how some cognitive variables (sustained attention, verbal fluency, interference, retrospective memory, selective attention) and personality factors (tested using the 16 PF-5) can help to explain the variance in the performance of prospective memory tasks. Our results show that the contribution of personality predictor variables is moderate and smaller than that of the cognitive variables for predicting the execution of ProM tasks in the laboratory. Furthermore the intervention of the personality variables differs depending on the ProM tasks used. Global self-control and rule-consciousness were the personality variables that contributed the most in the prediction of the scores in the ProM tasks that were used. 相似文献

Drawing on regulatory focus theory, the present work examined the motivations underlying intergroup attitudes expressed under conditions of majority versus minority support. In two studies, participants expressed their attitudes towards equality and non‐discrimination of foreigners and were informed that the equality and non‐discrimination principle was supported by either a majority or a minority. Regulatory focus was assessed as the extent to which participants felt promotion‐related and prevention‐related emotions when acting either inconsistently or consistently with the egalitarian principle. Results provided evidence supporting the hypothesis that attitudes are related to prevention emotions when supported by a majority, but to promotion emotions when supported by a minority.

Multiple victimization in adolescence is an issue that has received little research attention. Furthermore, adolescents are particularly vulnerable to victimization in different contexts. The aim of this study is to analyze correlates of multiple victimization in three contexts (home, school, and street). The following forms of victimization were considered: stealing, hitting, insulting, threatening, blackmailing, and weapon intimidation. Multiple victimization correlates explored were: sex, age, public/private school, socioeconomic status, quality of family relationships, and antisocial behavior. A probabilistic sample of 1,908 adolescents (ages 13 to 18) was used. Multilevel analyses were conducted to separate correlates at the individual level from those operating at the contextual level. Results show that gender, quality of family relationships, and deviant behavior were related to multiple victimization in adolescence. 相似文献

The present study investigated whether lexical access is affected by a regular phonological variation in connected speech: voice assimilation in French. Two associative priming experiments were conducted to determine whether strongly assimilated, potentially ambiguous word forms activate the conceptual representation of the underlying word. Would the ambiguous word form [sud] (either assimilated soute 'hold' or soude 'soda') facilitate "bagage" 'luggage', which is semantically related to soute but not to soude? In Experiment 1, words in either canonical or strongly assimilated form were presented as primes. Both forms primed their related target to the same extent. Potential lexical ambiguity did not modulate priming effects. In Experiment 2, the primes such as assimilated soute pronounced [sud] used in Experiment 1 were replaced with primes such as soude canonically pronounced [sud]. No semantic priming effect was obtained with these primes. Therefore, the effect observed for assimilated forms in Experiment 1 cannot be due to overall phonological proximity between canonical and assimilated forms. We propose that listeners must recover the intended words behind the assimilated forms through the exploitation of the remaining traces of the underlying form, however subtle these traces may be. 相似文献

Widiger and Simonsen (2005) state that given the limitations of the categorical model of Personality Disorders classification proposals are to be expected for dimensional classifications. The purpose of this paper is to test the alternative five factorial model (AFFM) of personality in a sample with PDs. Subjects were administered the ZKPQ to test the discriminant capacity of the AFFM in classifying subjects diagnosed with BPD (n = 74) vs normal-range controls (n = 148) paired by age and sex, and identifying sensitive and/or specific dimensions that can be of help in diagnosing BPD. The results showed that high scores on N-Anx and Imp-SS, and low scores on Act are prognostic factors for being diagnosed with BPD. Likewise, this model correctly classified 88% of subjects with a kappa index of 0.73. The AFFM of personality appears to have a substantial power for predicting SCID-II interview-based BPD diagnosis. 相似文献

Understanding how response time (RT) changes with manipulations has been critical in distinguishing among theories in cognition.
It is well known that aggregating data distorts functional relationships (e.g., Estes, 1956). Less well appreciated is a second
pitfall: Minimizing squared errors (i.e., OLS regression) also distorts estimated functional forms with RT data. We discuss
three properties of RT that should be modeled for accurate analysis and, on the basis of these three properties, provide a
hierarchical Weibull regression model for regressing RT onto covariates. Hierarchical regression model analysis of lexical
decision task data reveals that RT decreases as a power function of word frequency with the scale of RT decreasing 11% for
every doubling of word frequency. A detailed discussion of the model and analysis techniques are presented as archived materials
and may be downloaded from www.psychonomic.org/archive. 相似文献
