Emotionally charged pictorial materials are frequently used in phobia research, but no existing standardized picture database is dedicated to the study of different phobias. The present work describes the results of two independent studies through which we sought to develop and validate this type of database—a Set of Fear Inducing Pictures (SFIP). In Study 1, 270 fear-relevant and 130 neutral stimuli were rated for fear, arousal, and valence by four groups of participants; small-animal (N = 34), blood/injection (N = 26), social-fearful (N = 35), and nonfearful participants (N = 22). The results from Study 1 were employed to develop the final version of the SFIP, which includes fear-relevant images of social exposure (N = 40), blood/injection (N = 80), spiders/bugs (N = 80), and angry faces (N = 30), as well as 726 neutral photographs. In Study 2, we aimed to validate the SFIP in a sample of spider, blood/injection, social-fearful, and control individuals (N = 66). The fear-relevant images were rated as being more unpleasant and led to greater fear and arousal in fearful than in nonfearful individuals. The fear images differentiated between the three fear groups in the expected directions. Overall, the present findings provide evidence for the high validity of the SFIP and confirm that the set may be successfully used in phobia research.  相似文献

As a result of the increasing role of online advertising and strong competition among advertisers, intrusive techniques are commonly used to attract web users’ attention. Moreover, since marketing content is usually delivered to the target audience when they are performing typical online tasks, like searching for information or reading online content, its delivery interrupts the web user’s current cognitive process. The question posed by many researchers in the field of online advertising is: how should we measure the influence of interruption of cognitive processes on human behavior and emotional state? Much research has been conducted in this field; however, most of this research has focused on monitoring activity in the simulated environment, or processing declarative responses given by users in prepared questionnaires. In this paper, a more direct real-time approach is taken, and the effect of the interruption on a web user is analyzed directly by studying the activity of his brain. This paper presents the results of an experiment that was conducted to find the brain activity patterns associated with interruptions of the cognitive process by showing internet advertisements during a text-reading task. Three specific aspects were addressed in the experiment: individual patterns, the consistency of these patterns across trials, and the intra-subject correlation of the individual patterns. Two main effects were observed for most subjects: a drop in activity in the frontal and prefrontal cortical areas across all frequency bands, and significant changes in the frontal/prefrontal asymmetry index.  相似文献

We present a computational framework for attention-guided visual scene exploration in sequences of RGB-D data. For this, we propose a visual object candidate generation method to produce object hypotheses about the objects in the scene. An attention system is used to prioritise the processing of visual information by (1) localising candidate objects, and (2) integrating an inhibition of return (IOR) mechanism grounded in spatial coordinates. This spatial IOR mechanism naturally copes with camera motions and inhibits objects that have already been the target of attention. Our approach provides object candidates which can be processed by higher cognitive modules such as object recognition. Since objects are basic elements for many higher level tasks, our architecture can be used as a first layer in any cognitive system that aims at interpreting a stream of images. We show in the evaluation how our framework finds most of the objects in challenging real-world scenes.  相似文献

Environmental problems have been perceived as more worrying when they take place at greater distances. This phenomenon has been called “environmental hyperopia” ( 9 Uzzell, 2000; 7 Uzzell, Rice, Ballantyne, & Podlucká, 1994). Some studies have demonstrated that local environmental problems are perceived as being less important than the problems generated in other places, such as global warming or Amazon deforestation, unless the problem leads to an immediate risk. This article is part of a broader research programme, which tries to analyse the most relevant variables in the formation of pro‐environmental attitudes. More precisely, our intention is to explore the difference between attitudes about local and global environments. We present a study of the assessment of several environmental problems, in which 12 scales measured the importance given to these problems by a sample of students. The results were analysed with multidimensional methods, allowing us to establish temporal and space dimensions in the perception of environmental problems. The conclusions allowed us not only to explore the social representation of environmental problems, but also to establish priorities and recommendations for future environmental education programmes.  相似文献

Based on social‐cognitive theory ( 1 Bandura, 1997), this paper examined whether perceived self‐efficacy is a universal psychological construct that accounts for variance within various domains of human functioning. Perceived self‐efficacy is not only of a task‐specific nature, but it can also be identified at a more general level of functioning. General self‐efficacy (GSE) is the belief in one's competence to tackle novel tasks and to cope with adversity in a broad range of stressful or challenging encounters, as opposed to specific self‐efficacy, which is constrained to a particular task at hand. The study aimed at exploring the relations between GSE and a variety of other psychological constructs across several countries. Relations between general self‐efficacy and personality, well‐being, stress appraisals, social relations, and achievements were examined among 8796 participants from Costa Rica, Germany, Poland, Turkey, and the USA. Across countries, the findings provide evidence for associations between perceived general self‐efficacy and the selected variables. The highest positive associations were with optimism, self‐regulation, and self‐esteem, whereas the highest negative associations emerged with depression and anxiety. Academic performance is also associated with self‐efficacy as hypothesized. The replication across languages or cultures adds significance to these findings. The relations between self‐efficacy and other personality measures remained stable across cultures and samples. Thus, perceived general self‐efficacy appears to be a universal construct that yields meaningful relations with other psychological constructs.  相似文献

The aim of this study was to assess the relationships between depressive symptoms and symptom-centered panic-fear (P-F), and reports of health-related quality of life (HRQOL), in persons with near-fatal asthma (NFA), controlling for age, gender, and pulmonary function. Forty persons with NFA were interviewed. Sociodemographic and clinical asthma-related information were collected. HRQOL was assessed by the SF-36 Health Questionnaire, depressive symptoms were assessed by the Beck Depression Inventory, and P-F was assessed by the P-F scale of the Asthma Symptom Checklist. Multiple regression analyses were carried out with the Physical Component Summary (PCS) and the Mental Component Summary (MCS) of the SF-36 as a dependent variable, and depressive symptoms, P-F, age, gender, and pulmonary function as independent variables. Results showed that P-F and age were associated with PCS, whereas depressive symptoms accounted for a marked percentage of the variance explained in MCS. Neither gender nor pulmonary function were related to HRQOL. In conclusion, depressive symptoms and P-F play an important role in how persons with NFA assess their HRQOL. These patient-centered variables are potentially modifiable and may offer new ways to intervene in order to improve HRQOL in persons with NFA.  相似文献

Confirmatory factor analyses (CFA) carried out in the last decades to test the Five-factor simple structure have generally obtained negative results. McCrae, Zonderman, Costa, Bond, and Paunonen (1996) suggested that CFA limitations were the main cause of such negative results. They also claim that Procrustes Orthogonal rotation method is an adequate procedure to test the replicability of the Five-factor structure. The aim of the present paper is twofold: (A) comparing several Exploratory factor procedures (including the Procrustes rotation) to test what is the most appropriate one to analyse the replicability of the Five-factor structure, and (B) replicating the CFA results of the McCrae et al.’s study with a larger number of subjects. The normative American (N = 1000), and Spanish (2000) standardization samples of the NEO-PI-R, together with an independent university sample (N = 948) were analysed. Results were replicated in the three samples, and suggest that: (1) structural properties of the Five-factor model, as measured by the NEO-PI-R, are invariant irrespective of the Exploratory factor procedure used, and (2) when CFA limitations are surpassed, the Five-factor structure is supported.  相似文献

Background/Objective: Alzheimer-type dementia is one of the most frequent causes of dependence in an aging population, which combines with a considerable demand for care. Furthermore, when the caregiver is a family member or person without specialized training, such care impacts on that person's health. The Inventory of Overburden in Alzheimer's Patient Family Caregivers with no Specialized Training (IPSO-CA24) was designed to find out the needs of these caregivers and evaluate the caregiver's burden or distress. Method: The psychometric properties of the questionnaire were analyzed (in a reliability analysis, exploratory factor analysis and confirmatory analysis) based on the responses of 255 caregivers. Results: The factor analyses showed a six-factor structure (Reaction to diagnosis, Physical health, Psychological symptomatology (caretaker), Behavioral symptomatology (patient), Knowledge of the illness, and Level of dependence) explaining 66.52% of the total variance with a reliability of .75 to .93. Support was also found for its convergent validity. Conclusions: The IPSO-CA24 responds to the need for an instrument enabling multidimensional evaluation of the burden on the family caregiver without specialized training.  相似文献

Background/Objective: Emotional intelligence is a variable which has been the subject of significantly increased research in recent years. Relationships have been shown with both physical and psychological problems. The aim of this study is to analyse the direct and indirect effect that emotional intelligence exerts over the manifestation of physical and psychological clinical symptomatology and to severe disorders such as burnout syndrome in a professional group in which social function is fundamental. Method: So that, 881 Latin-American catholic priests (Mage = 45.89; SDage = 11.58) were evaluated using the Trait Meta-Mood Scale-24, the Maslach Burnout Inventory-22 and the General Health Questionnaire-28. Results: Using path analysis, emotional intelligence, especially Attention and Emotional Clarity, shows a high effect on psychological and somatic issues. Conclusions: Thus, both specific disorders and general well-being are related to emotional intelligence. Providing effective emotional intelligence training sessions seems to be able to reduce possible physical and emotional disorders.  相似文献

Research shows that contextual diversity (CD; the number of different contexts in which a word appears within a corpus) constitutes a better predictor of reading performance than word frequency (WF), that it mediates the access to lexical representations, and that controlling for contextual CD abolishes the effect of WF in lexical decision tasks. Despite the theoretical relevance of these findings for the study of serial memory, it is not known how CD might affect serial recall performance. We report the first independent manipulation of CD and WF in a serial recall task. Experiment 1 revealed better performance for low CD and for high WF words independently. Both effects affected omissions and item errors, but contrary to past research, word frequency also affected order errors. These results were confirmed in two more experiments comparing pure and alternating lists of low and high CD (Experiment 2) or WF (Experiment 3). The effect of CD was immune to this manipulation, while that of WF was abolished in alternating lists. Altogether the findings suggest a more difficult episodic retrieval of item information for words of high CD, and a role for both item and order information in the WF effect.  相似文献
