The stop signal task is widely adopted to assess motor inhibition performance in both clinical and non-clinical populations. Several recent studies explored the influence of strategic approaches to the task. In particular, response slowing seems to be a strategic approach commonly adopted to perform the task. In the present study, we compared a standard version with a strategic version of the task, in which participants were explicitly instructed to slow down responses. Results showed that the instructed slowing did not affect the main inhibition measure, thus confirming the robustness of the stop signal index. On the other hand, it apparently changed the nature of the task, as shown by the lack of correlation between the standard and the strategic versions. In addition, we found a specific influence of individual characteristics on slowing strategies. In the standard version, adherence to task instructions was positively correlated with compliant traits of personality. Despite instructions to maximize response speed, non-compliant participants preferred to adopt a slowing strategy in the standard version of the task, up to a speed level similar to the strategic version, where slowing was required by task instructions. Understanding the role of individual approach to the task seems to be crucial to properly identify how participants cope with task instructions. 相似文献

Contrasting results have been reported regarding the phonetic acquisition of bilinguals. A lack of discrimination has been observed for certain native contrasts in 8-month-old Catalan-Spanish bilingual infants (Bosch & Sebastián-Gallés, 2003a), though not in French-English bilingual infants (Burns, Yoshida, Hill & Werker, 2007; Sundara, Polka & Molnar, 2008). At present, the data for Catalan-Spanish bilinguals constitute an exception in the early language acquisition literature. This study contributes new findings that show that Catalan-Spanish bilingual infants do not lose the capacity to discriminate native contrasts. We used an adaptation of the anticipatory eye movement paradigm (AEM; McMurray & Aslin, 2004) to explore this question. In two experiments we tested the ability of infants from Catalan and Spanish monolingual families and from Catalan-Spanish bilingual families to discriminate a Spanish-Catalan common and a Catalan-specific vowel contrast. Results from both experiments revealed that Catalan-Spanish bilingual infants showed the same discrimination abilities as those shown by their monolingual peers, even in a phonetic contrast that had not been discriminated in previous studies. Our results demonstrate that discrimination can be observed in 8-month-old bilingual infants when tested with a measure not based on recovery of attention. The high ratio of cognates in Spanish and Catalan may underlie the reason why bilinguals failed to discriminate the native vowels when tested with the familiarization-preference procedure but succeeded with the AEM paradigm. 相似文献

The effect of interactivity on identification with characters in audiovisual fiction was observed. 310 participants were asked to watch a film in one of these two conditions: 1) interactive (they selected the plot), and 2) non-interactive (they consumed the fiction in a conventional way). After watching the movie, they completed a questionnaire with the EDI scale of identification and empathy with characters, created by Igartua and Paez. The capacity to intervene in the configuration of the plot (interactivity) affected identification with characters. The results provide data about the psychology of media and interactivity in communication and allow us to understand the processes of empathy and identification with characters. 相似文献

The agreement between teachers’ and parents’ ratings of the prevalence of DSM-IV attention deficit hyperactivity disorder (ADHD) symptoms and the concordance of the factor structure of ADHD symptoms was analyzed in a sample of 653 Spanish schoolchildren aged 4 to 12 divided into two age groups. The prevalence of ADHD symptoms ranged between 0.66 and 16.73% and was higher when the rater was the teacher. Agreement between parents and teachers was low. Confirmatory factor analysis (CFA) shows a slightly better fit for the three-factor model (Inattention, Hyperactivity and Impulsivity) than for the two-factor model (Inattention and Hyperactivity–impulsivity), except for parents’ ratings in the sample of children under six. CFA using a multitrait–multimethod model (CFA-MTMM) shows similar results. 相似文献

Recent research has found that people with Irritable Bowel Syndrome (IBS) and those with Inflammatory Bowel Disease (IBD) show a relative deficit in verbal IQ, compared to their own performance IQ, and the IQ of a healthy comparison group. It has been suggested that the elevated prevalence of left-handedness shown in previous studies investigating people with IBD is due to compromised left-hemisphere development. This may be associated with a decrement in certain cognitive functions such as verbal IQ. A shift in brain dominance from left to right has been found in many atopic and immunological diseases as well as in autonomic dysfunctions. It was uncertain whether this would apply to people with IBS, a functional disorder in which the cause or causes remain unclear. Therefore, the aim of this preliminary study was to investigate whether people with IBS have an increased prevalence of left-handedness. It was found that there was an association between IBS and left-handedness, showing that further research on this association both in IBS and other functional disorders (as well as on the similarities between IBS and IBD) is warranted. 相似文献

Consensual validity parameters of the Zuckerman-Kuhlman personality questionnaire: evidence from self-reports and spouse reports 总被引:1,自引:0,他引:1
One way of validating questionnaire responses is correlating them with ratings made by external assessors who know the ratee well: This is known as consensual validity. In this study, we assessed the consensual validity of the Zuckerman-Kuhlman Personality Questionnaire (ZKPQ; Zuckerman, 2002; Zuckerman, Kuhlman, Joireman, Teta, & Kraft, 1993). A multitrait-multimethod matrix of self-reported and spouse reported personality ratings was used to establish convergent and discriminant validity by means of Campbell and Fiske's (1959) evaluative criteria. Self-reports of 86 men and 85 women were correlated with their spouses' reports. Intraclass correlations ranged from .47 to .63 for the 5 dimensions, providing strong evidence of convergent and discriminant validity. The results obtained favor the use of the ZKPQ as a valid self-report measure of personality traits. 相似文献

Inhibition of return (IOR) is a response delay that occurs when the target is preceded by an irrelevant stimulus (cue) at
the same location. IOR can be object based, as well as location based. The aim of the present study was to investigate the
role of the pragmatic features of a visually presented object in causing IOR. Two experiments were carried out using different
objects as stimuli, for which the graspable part (affordance) was clearly defined. The presentation of a whole object, with
the part commonly used to grasp it located below, served as a cue. The presentation of either the graspable or the ungraspable
part of the cued or uncued object served as the target Results showed that responses were slower when the graspable part was
shown in the cued location than when the ungraspable part was shown in the same location. The effect was apparently linked
to the kind of action necessary to grasp an object. 相似文献

Previous papers have mainly demonstrated the presence of cognitive impairment in patients with multiple sclerosis (MS), these changes have been traditionally associated with the later stages of the disease. In the current study, a comprehensive neuropsychological battery was administered to 216 relapsing-remitting MS patients with mild clinical disability (EDSS相似文献
