Developmental studies have demonstrated that cognitive processes such as attention, suppression of interference and memory develop throughout childhood and adolescence. However, little is currently known about the development of top-down control mechanisms and their influence on cognitive performance. In the present study, we used functional magnetic resonance imaging to investigate modulation of activity in the ventral visual cortex in healthy 7–11-year-old children and young adults. The participants performed tasks that required attention to either face (Fs task) or scene (Sf task) images while trying to ignore distracting scene or face images, respectively. A face-selective area in the fusiform gyrus (fusiform face area, FFA) and an area responding preferentially to scene images in the parahippocampal gyrus (parahippocampal place area, PPA) were defined using functional localizers. Children responded slower and less accurately in the tasks than adults. In children, the right FFA was less selective to face images and regulation of activity between the Fs and Sf tasks was weaker compared to adults. In the PPA, selectivity to scenes and regulation of activity, there according to the task demands were comparable between children and adults. During the tasks, children activated prefrontal cortical areas including the middle (MFG) and superior (SFG) frontal gyrus more than adults. Functional connectivity between the right FFA and left MFG was stronger in adults than children in the Fs task. Children, on the other hand, had stronger functional connectivity than adults in the Sf task between the right FFA and right PPA and between right MFG and medial SFG. There were no group differences in the functional connectivity between the PPA and the prefrontal cortex (PFC). Together the results suggest that, in 7–11-year-old children, the FFA is still immature, whereas the selectivity to scenes and regulation of activity in the PPA is comparable to adults. The results also indicated functional immaturity of the PFC in children compared to adults and weaker connectivity between the PFC and the rFFA, explaining the weaker regulation of activity in the rFFA between the Fs and Sf tasks. 相似文献

Background: Little is known about the impact of interventions targeting chronic stress levels on clinical outcomes among myocardial infarction (MI) patients with increased levels of stress. Objectives: To examine the impact of the addition of brief strategic therapy (BST) to usual care (UC) on clinical outcomes in first MI patients with increased levels of stress. Design: Eighty-one patients were randomly assigned to BST in conjunction with UC (medical treatment, risk factor information, and guidance on unhealthy behavior change) or to UC. Methods: The outcome measures were scores on the Perceived Stress Scale, reinfarction and cardiac mortality rates, and scores on the Health Survey. Measures were taken before, post-treatment, and at two follow-ups. Results: Patients subjected to BST showed reduced perceived stress at post-treatment and maintained decreased levels at follow-ups. At 1-year follow-up, they had a lower rate of non-fatal reinfarction, and at 2.5-year follow-up, they had a lower rate of fatal reinfarction. Their mental and physical health was improved at post-treatment and this was sustained at follow-ups. Conclusion: The addition of BST to UC favorably influences the disease course after MI in patients with increased levels of stress. 相似文献

The typology of interlocutors in internal dialogues comprises four main emotional types: faithful friend, ambivalent parent, proud rival, and helpless child. The two studies presented in the article aimed to identify which types appear in integrative and which in confrontational internal dialogues. Additionally, Study 2 compared the functions performed by these two types of dialogues. Both Study 1 (N = 101) and Study 2 (N = 99) confirmed the hypothesis that faithful friend and ambivalent parent are interlocutors typical of integrative dialogues, whereas proud rival and helpless child are characteristic for confrontational ones. It was also found that integrative dialogues perform certain functions—namely, support, bond, insight, and self-guiding—to a greater degree than confrontational dialogues. 相似文献

The two studies presented in the article aimed to empirically verify the tentative typology of internal interlocutors in self-talk proposed in a previous research project. The typology comprised four emotional types: Faithful Friend, Ambivalent Parent, Proud Rival, and Helpless Child. Study 1 involved 98 participants (49 women) and Study 2 involved 114 (55 women), mostly students. In both studies, the names of internal interlocutors were generated by participants as qualitative data, quantified by reference to the standard set of affect terms, and, as affective patterns, subjected to clustering. Study 2 fully confirmed the recent results, whereas Study 1 revealed a new interlocutor type instead of Helpless Child – Calm Optimist. The conducted studies confirm the existence of four main types of inner interlocutors and provide a reason to verify the existence of Calm Optimist. 相似文献

In this article, we trace and elucidate Heidegger’s radical re-thinking on the relation between science and technology from about 1940 until 1976. A range of passages from the Gesamtausgabe seem to articulate a reversal of the primacy of science and technology in claiming that “Science is applied technology.” After delving into Heidegger’s reflection on the being of science and technology and their “coordination,” we show that such a claim is essentially grounded in Heidegger’s idea that “Science and technology are the Same [das Selbe].” In addition, we argue that, although different ontic epochs can be distinguished in the evolvement of science and/or technology, for Heidegger there is only one unique ontological Epoch of modernity that encompasses various ontic epochs. Therefore, the change from an “epoch of objectivity” to an “epoch of orderability [Bestellbarkeit]” cannot be considered to be an ontological shift. Furthermore, it is not right to ascribe to Heidegger the view that the development of quantum physics signals the beginning of a new ontological Epoch. 相似文献

Interest in the distinction between integrative and confrontational internal dialogues has been growing, as research suggests numerous positive functions of the former compared to the latter. The article proposes a theoretical approach to integration and confrontation in internal dialogue and an empirical method of measuring these processes. Exploratory research is also presented that seeks to identify personality‐related and situational determinants of integration and confrontation in internal dialogue simulating social relationships. Canonical correlation analysis did not establish personality determinants but it did reveal situational determinants (understood as cognitive interpretation of the enacted situation) behind integration and confrontation in internal dialogue. Perceiving the internal interlocutor as similar to the dialogue's author is associated with the author's integrative attitude. An increase in the wishfulness of the dialogue is accompanied by an increase in the author's confrontational attitude and the interlocutor's integrative attitude. 相似文献
