The effect of lexicality and stimulus length was studied in 32 third- and fourth-grade Italian dyslexics and in 86 age-matched controls. A visual lexical decision task was used. As proposed by Faust et al. (1999), the results were analyzed in terms of raw reaction time (RT) data and using the z-score transformation to control for the presence of overadditivity effects. In terms of RTs, dyslexics showed a larger difference between words and nonwords (lexicality effect) and between short and long stimuli (length effect) than proficient readers. When data were transformed into z scores, only the group by length interaction remained significant while that with lexicality vanished. This pattern indicates that stimulus length has a specific role in Italian dyslexics’ reading deficit; in contrast, slowness in responding to nonwords was not specific but was interpreted as one aspect of dyslexics’ general inability to deal with alphabetical material (overadditivity effect). 相似文献

We investigated the characteristics of route and survey processing of a unique complex virtual environment both at the behavioral
and brain levels. Prior to fMRI scanning, participants were trained to follow a route and to learn the spatial relationships
between several places, acquiring both route and survey knowledge from a ground-level perspective. During scanning, snapshots
of the environment were presented, and participants were required to either indicate the direction to take to follow the route
(route task), or to locate unseen targets (survey task). Data suggest that route and survey processing are mainly supported
by a common occipito-fronto-parieto-temporal neural network. Our results are consistent with those gathered in studies concerning
the neural bases of route versus survey knowledge acquired either from different perspectives or in different environments.
However, rather than arguing for a clear distinction between route and survey processing, “mixed” strategies are likely to
be involved when both types of encoding take place in the same environment. 相似文献

Overall reinforcer rate appears to affect choice. The mechanism for such an effect is uncertain, but may relate to reinforcer rate changing the discrimination of the relation between stimuli and reinforcers. We assessed whether a quantitative model based on a stimulus‐control approach could be used to account for the effects of overall reinforcer rate on choice under changing time‐based contingencies. On a two‐key concurrent schedule, the likely availability of a reinforcer reversed when a fixed time had elapsed since the last reinforcer, and the overall reinforcer rate was varied across conditions. Changes in the overall reinforcer rate produced a change in response bias, and some indication of a change in discrimination. These changes in bias and discrimination always occurred quickly, usually within the first session of a condition. The stimulus‐control approach provided an excellent account of the data, suggesting that changes in overall reinforcer rate affect choice because they alter the frequency of reinforcers obtained at different times, or in different stimulus contexts, and thus change the discriminated relation between stimuli and reinforcers. These findings support the notion that temporal and spatial discriminations can be understood in terms of discrimination of reinforcers across time and space. 相似文献

Abstract Rescue workers are frequently exposed to highly stressful situations during their everyday work activity. Stress and coping theory emphasizes the interaction between primary and secondary appraisal in determining coping responses to stressful events and quality of life. According to Social Cognitive Theory, stress reactions depend on self-appraisal of coping capabilities. The present study investigated whether self-efficacy moderates the relationship between stress appraisal and professional quality of life. A self-administered questionnaire was submitted to a sample of 451 Italian rescue workers (firefighters, paramedics, and medical technicians), including the Professional Quality of Life Scale, which measures three dimensions of emergency workers' quality of working life: compassion fatigue, burnout, and compassion satisfaction. Multiple regression analyses indicated that the relationship between stress appraisal and professional quality of life was significant only among rescue workers with low levels of self-efficacy but not among those with higher levels of self-efficacy. These results confirmed the expectations based on Social Cognitive Theory that self-efficacy buffers the impact of perceived stressful encounters on professional quality of life. Results suggest the usefulness of interventions aimed at increasing rescue workers' psychosocial skills. 相似文献

ABSTRACTThis research wants to verify the effectiveness of couple's treatment, when a neurodegenerative disease affects one of the two partners. The disease affects not only the ailing individual, but also the dynamics within the couple. Fourteen patients affected by neurodegenerative diseases participated in an emotionally focused couple therapy (EFT) with their spouses. We collected a measure of the quality of life (SF-36) and relationship satisfaction (DAS) at the beginning and at the end of the treatment for both partners. The results show an improvement in quality of life and couple contentment, underlining the usefulness of such a psychotherapeutic intervention on the couple. 相似文献

Image theory was tested in the context of Italian/American relationships. Participants were Italian students. In addition to the images of ally, barbarian, imperialist, enemy, a new image was suggested: that of father. We predicted that political orientation would affect the structural perceptions (goal compatibility, relative power, relative status), and, as a consequence, the image of Americans: right-wing participants should prefer the images of father and ally, while left-wing participants should associate Americans with barbarian. Findings generally supported our predictions; also the figure of father obtained some support. The theoretical and practical implications of results are discussed. 相似文献

During central fixation, a moving pattern of nontargets induces repeated temporary blindness to even salient peripheral targets: motion-induced blindness (MIB). Hitherto, behavioral measures of MIB have relied on subjective judgments. Here, we offer an objective alternative that builds on earlier findings regarding the effects of MIB on the detectability of physical target offsets. We propose a small modification of regular MIB displays: Following a variable duration (lead time), one of the targets is physically removed. Subjects are to respond immediately afterward. We hypothesize that illusory target offsets, caused by MIB, are mistaken for physical target offsets and that errors should thus increase with lead time. Indeed, for both nonsalient and salient targets, we found that detection accuracy for physical target offsets dramatically decreased with lead time. We conclude that target offset detection accuracy is a valid objective measure of MIB. With our method, effects of guessing are minimal, and the fitting of psychometric functions is straightforward. In principle, a staircase extension—for more efficient data collection—is also possible. 相似文献

The purpose of this paper is to show how the interaction between Kantian ethics and some aspects of Heideggerian philosophy can lead to the model of a subject in immediate relationship with others and with his or her community. The positions of Jean-Luc Nancy and Jacques Derrida on this question are presented in contrast with those of Alain Renaut and Emmanuel Lévinas to elucidate their differing ways of interpreting the relationship between Kant and Heidegger with regard to ethics, apriorism, and subjectivity. 相似文献

Two prominent cognitive capacity limitations are the maximal number of objects we can place in working memory (WM) and the maximal number of objects we can track in a display. Both are believed to have a numeric value of 3 or 4, which has led to the proposal that we have a general cognitive capacity, and that this capacity is most likely linked to limitations of how many objects we can attend simultaneously. Based on previous results showing that we can memorize more objects if they come from different categories than if they come from the same category (e.g., Feigenson & Halberda, 2008; Wong, Peterson, & Thompson, 2008; Wood, 2008), we compare how category-based grouping affects performance for WM and multiple object tracking (MOT). We present participants with either “pure” displays of either cars or faces, or with “mixed” displays of cars and faces. Overall, the effects of category are weak. In some analyses but not others, we replicate the mixed advantage for WM, albeit with a small effect size. In contrast, we observe a weak pure advantage for MOT tasks, at least in a meta-analysis of five experiments, but not in all experiments. Accordingly, WM and MOT tasks differed significantly in their sensitivity to category membership. We also find that WM is slightly better for faces than for cars, but that no such difference exists for MOT. We tentatively suggest that cognitive capacity limitations in different domains are at least partially due to the limitations of distinct mechanisms. 相似文献
