We investigate how vision affects haptic performance when task-relevant visual cues are reduced or excluded. The task was to remember the spatial location of six landmarks that were explored by touch in a tactile map. Here, we use specially designed spectacles that simulate residual peripheral vision, tunnel vision, diffuse light perception, and total blindness. Results for target locations differed, suggesting additional effects from adjacent touch cues. These are discussed. Touch with full vision was most accurate, as expected. Peripheral and tunnel vision, which reduce visuo-spatial cues, differed in error pattern. Both were less accurate than full vision, and significantly more accurate than touch with diffuse light perception, and touch alone. The important finding was that touch with diffuse light perception, which excludes spatial cues, did not differ from touch without vision in performance accuracy, nor in location error pattern. The contrast between spatially relevant versus spatially irrelevant vision provides new, rather decisive, evidence against the hypothesis that vision affects haptic processing even if it does not add task-relevant information. The results support optimal integration theories, and suggest that spatial and non-spatial aspects of vision need explicit distinction in bimodal studies and theories of spatial integration.  相似文献

Bo?kovi?'s explanatory procedure and his concept of explanation represents a certain departure from Newton's causal theory and his theory of explanation. Apart from particular elements of causal explanation, Bo?kovi? developed an alternative, non‐causal explanatory strategy. In this paper two different elements of this strategy are discussed: (i) the micro‐reductive explanatory strategy based on Bo?kovi?'s idea of determination, and (ii) a type of explanation of a theory by means of a more general law, through a thought‐experiment. In addition, an outline of the proposed (iii) ‘argument theory’ of explanation in his mature period is made. These aspects are considered with respect to the realist and anti‐realist elements in Bo?kovi?'s epistemology.  相似文献

In the paper there are introduced and discussed the concepts of an indexed category with quantifications and a higher level indexed category to present an algebraic characterization of some version of Martin-Löf Type Theory. This characterization is given by specifying an additional equational structure of those indexed categories which are models of Martin-Löf Type Theory. One can consider the presented characterization as an essentially algebraic theory of categorical models of Martin-Löf Type Theory. The paper contains a construction of an indexed category with quantifications from terms and types of the language of Martin-Löf Type Theory given in the manner of Troelstra [11]. The paper contains also an inductive definition of a valuation of these terms and types in an indexed category with quantifications.  相似文献

In this article I look at the methodology of one the most unique figures in Russian philosophy—Merab Mamarda?vili—who was known for his focus on consciousness. According to him, the application of the subject–object dualism to the analysis of consciousness leads to a series of complications. Within the phenomenological framework of intentionality there is an interwining of perspective and object to which this perspective is directed. As soon as we try to apply to consciousness subject–object schemes, then we immediately come across paradoxes. It is impossible to determine consciousness by means of subject–object, not only because it is neither an object nor a subject, but also because consciousness inevitably turns out to be “prior” to such distinctions.  相似文献

Developmental prosopagnosia (DP) is a severe impairment in identifying faces that is present from early in life and that occurs despite no apparent brain damage and intact visual and intellectual function. Here, we investigated what aspects of face processing are impaired/spared in developmental prosopagnosia by examining a relatively large group of individuals with DP (n = 8) using an extensive battery of well-established tasks. The tasks included measures of sensitivity to global motion and to global form, detection that a stimulus is a face, determination of its sex, holistic face processing, processing of face identity based on features, contour, and the spacing of features, and judgments of attractiveness. The DP cases showed normal sensitivity to global motion and global form and performed normally on our tests of face detection and holistic processing. On the other tasks, many DP cases were impaired but there was no systematic pattern. At least half showed deficits in processing of facial identity based on either the outer contour or spacing of the internal features, and/or on judgments of attractiveness. Three of the eight were impaired in processing facial identify based on the shape of internal features. The results show that DP is a heterogeneous condition and that impairment in recognizing faces cannot be predicted by poor performance on any one measure of face processing.  相似文献

Predictions of social identity and self‐categorization theories about the relevance of social identification in organizational contexts are presented. We propose that different foci of identification (e.g. with own career, team, organization, occupation) as well as different dimensions of organizational identification (cognitive, affective, evaluative, and behavioural) can be separated. Furthermore, these different aspects of organizational identification are assumed to be differentially associated with work‐related attitudes and behaviours. Predictions are first tested in a questionnaire study of 515 German school teachers. Confirmatory factor analyses demonstrated that dimensions and foci can indeed be differentiated. In addition, results indicate that different aspects correlate differentially with different criteria. The results are cross‐validated in two samples of 233 German school teachers and 358 bank accountants, respectively.  相似文献

Self-regulation plays an important role in successful adaptation to preschool and school contexts as well as in later academic achievement. The current study relates different aspects of self-regulation such as temperamental effortful control and executive functions (updating, inhibition, and shifting) to different aspects of adaptation to school such as learning-related behavior, school grades, and performance in standardized achievement tests. The relationship between executive functions/effortful control and academic achievement has been established in previous studies; however, little is known about their unique contributions to different aspects of adaptation to school and the interplay of these factors in young school children. Results of a 1-year longitudinal study (N=459) revealed that unique contributions of effortful control (parental report) to school grades were fully mediated by children's learning-related behavior. On the other hand, the unique contributions of executive functions (performance on tasks) to school grades were only partially mediated by children's learning-related behavior. Moreover, executive functions predicted performance in standardized achievement tests exclusively, with comparable predictive power for mathematical and reading/writing skills. Controlling for fluid intelligence did not change the pattern of prediction substantially, and fluid intelligence did not explain any variance above that of the two included aspects of self-regulation. Although effortful control and executive functions were not significantly related to each other, both aspects of self-regulation were shown to be important for fostering early learning and good classroom adjustment in children around transition to school.  相似文献

Psychology is frequently confronted with mind-body issues—is there a way by which mentalist and physical approaches to cognition can be integrated? Can the intentional attributes of mind be understood in scientific terms? The authors propose that synergetics, the theory of non-linear complex systems, offers steps towards a possible solution to this conundrum. In particular, we maintain that an essential property of self-organized pattern formation lies within its functionality, this being the ability to optimize, respond and adapt ‘meaningfully’ to environmental constraints. Patterns become functional because they consume in a most efficient manner the gradients which cause their evolution, thereby making synergetic pattern formation appear ‘intentional’. We therefore posit that self-organization phenomena may afford basic explanations for the adaptive, intentional and purposive behavior of many complex systems, in particular of cognitive systems. This present approach elaborates on the second law of thermodynamics.  相似文献

Today local, national and international ethics committees have become an effective means of social regulation in many European countries. Science itself is an important precondition for the development of bioethical knowledge and ethics expertise. Cultural, social, historical and religious preconditions can facilitate different forms and methods of ethics expertise in each country. Ukrainian ethics expertise has some methodological problems connected with its socio-cultural, historical, science and philosophy development particularities. In this context, clarification of some common legitimacies or methodological approaches to ethics committee (EC) phenomena such as globalization, scientization and the prioritization of an ethics paradigm are very important. On the other hand, elaborate study and critical analysis of international experience by Ukraine and other Eastern European countries will provide the integration of their local and national ethics expertises into a world bioethics ethos. An earlier version of this paper was presented at the 6th International Bioethics Conference entitled ‘The Responsible Conduct of Basic and Clinical Research’, held in Warsaw, Poland, 3–4 June 2005.  相似文献

We compared the predictions from several kinds of metamemory judgments (on the same set of items), both in terms of their predictive accuracy and in terms of the commonality of predictions. Undergraduates made judgments about the ease with which they could learn each item in a list (ease-of-learning judgments); then they learned every item, either to a minimal criterion of learning or with overlearning, and made judgments about how well they knew each item (judgments of knowing); finally, they returned 4 weeks later for a retention session and made feeling-of-knowing judgments on every time they could not recall, after which a recognition test assessed predictive accuracy. Ease-of-learning judgments had the least predictive accuracy. Surprisingly, however, the recognition of nonrecalled items was predicted equally well by judgments of knowing (made 4 weeks earlier) as by feeling-of-knowing judgments (made immediately prior to recognition). Moreover, those two kinds of judgments were only weakly correlated with each other, which implies that they do not tap memory in the same way.  相似文献

Few people would doubt that alternative therapies have become increasingly popular over the last two decades in Western societies. The expulsion of evil spirits, otherwise known as ‘deliverance’, in order to overcome physical, psychological and emotional problems might appear to be on the fringe of the most ‘fringe’ alternatives. Nevertheless, in Christian charismatic circles the practice is of central importance over and above the apparent aim of spiritual healing. This article explains what deliverance involves with reference to observations and interviews conducted during field work study at deliverance meetings and training sessions. I conclude by exploring a number of sociological themes which might allow an insight into its wider frinctions. In doing so I will contend that deliverance provides a purpose for the charismatic community in upholding boundary maintenance, as well as integrating and sustaining the individual within the collective.  相似文献

This research draws from social cognitive theory to develop a construct known as moral attentiveness, the extent to which an individual chronically perceives and considers morality and moral elements in his or her experiences, and proposes that moral attentiveness affects a variety of behaviors. A series of 5 studies with undergraduates, MBA students, and managers were conducted to create and validate a reliable multidimensional scale and to provide evidence that moral attentiveness is associated with (a) the recall and reporting of self- and others' morality-related behaviors, (b) moral awareness, and (c) moral behavior. Results of the studies suggest that moral attentiveness has a significant effect on how individuals understand and act in their moral worlds.

When do children become consciously aware of events in the world? Five possible strategies are considered for their usefulness in determining the age in question. Three of these strategies ask when children show signs of engaging in activities for which conscious awareness seems necessary in adults (verbal communication, executive control, explicit memory), and two of the strategies consider when children have the ability to have the minimal form of higher-order thought necessary for access consciousness and phenomenal consciousness, respectively. The tentative answer to the guiding question is that children become consciously aware between 12 and 15 months (+/-3 months).  相似文献

This paper presents findings from an intensive, mixed methods case study of one session of psychoanalytic parent–infant psychotherapy (PPIP) addressing early relational trauma, and aims to shed light on the multimodal interactive processes that take place in the moment-to-moment exchanges comprising the therapeutic encounter. Different research methods were used on video material from PPIP sessions, including microanalysis of adult–infant interactions, discourse analysis of talk, and coding systems developed to study parent–infant interaction. These different perspectives were brought together with the clinical narrative to illuminate the complex, dynamic processes of parent–infant–therapist interaction. More specifically, the detailed analysis of one interactive episode revealed brief behavioral manifestations of fearful and disoriented states of mind, reflecting dysregulated interaction between mother and infant, which also powerfully affected the therapist. The processes through which the therapist gradually resolves this rupture are also described in detail. Through this pilot study, we were able to show that it is possible to systematically study the process of PPIP. The study contributes to the growing psychotherapy research literature that takes into account both the verbal domain and implicit, interactional processes in therapeutic practice, and underscores the therapist's comprehensive engagement in the therapeutic process.  相似文献

Background

Therapists and counsellors increasingly use online video applications to offer treatment in place of face-to-face delivery. In the alcohol treatment sector, this offers a range of potential benefits for treatment providers. However, the impact of working remotely via video on the therapeutic relationship remains unclear and under-researched.

Aims

This study aimed to explore how alcohol treatment clients make sense of the relational aspects of therapy delivered remotely, and to examine how the use of remote therapy might disrupt existing ideas around the therapeutic relationship.

Methodology

This study utilised a qualitative design using thematic analysis, with 15 participant interviews with adult service users from a single treatment provider. All participants had previously undertaken at least four 1-h online therapy sessions.

Findings

The themes that were identified highlighted the significance of the participants' own homes as the site of therapy, with emphasis on the comfort of the home, and the presence of family members and pets. Participants stressed the importance of viewing the face of the therapist, the establishment of a therapeutic bond and specific therapist qualities. Participants also reflected on issues around denial and avoidance associated with self-image and identity.

Discussion

There are nuanced and potentially unforeseen consequences of undertaking therapy for alcohol problems via video, relating to the significance of the therapy environment and relationship between client and therapist. This may include issues of shame, denial and avoidance, which are of particular significance for clients experiencing difficulties associated with alcohol.  相似文献

The Openness/Intellect (O/I) model proposes that Openness to Experience has two major facets—Openness and Intellect—that can be measured with the Big Five Aspect Scales (BFAS). Thus far, however, research has not shown distinct, unique relationships between the Openness and Intellect aspects and other outcomes. The present research evaluated the relationships between Openness and Intellect with two outcomes: creative behavior and achievement (conceptually closer to Openness) and fluid intelligence (conceptually closer to Intellect). Young adults completed the BFAS, several measures of fluid intelligence, and several measures of creative achievement. Latent variable models indicated that the Openness aspect significantly predicted creativity but not fluid intelligence; the Intellect aspect, in contrast, significantly predicted fluid intelligence but not creativity. The findings thus offer support for the validity of the O/I model.  相似文献

The sound “OM” is believed to bring mental peace and calm. The cortical activation associated with listening to sound “OM” in contrast to similar non-meaningful sound (TOM) and listening to a meaningful Hindi word (AAM) has been investigated using functional magnetic resonance imaging (MRI). The behaviour interleaved gradient technique was employed in order to avoid interference of scanner noise. The results reveal that listening to “OM” sound in contrast to the meaningful Hindi word condition activates areas of bilateral cerebellum, left middle frontal gyrus (dorsolateral middle frontal/BA 9), right precuneus (BA 5) and right supramarginal gyrus (SMG). Listening to “OM” sound in contrast to “non-meaningful” sound condition leads to cortical activation in bilateral middle frontal (BA9), right middle temporal (BA37), right angular gyrus (BA 40), right SMG and right superior middle frontal gyrus (BA 8). The conjunction analysis reveals that the common neural regions activated in listening to “OM” sound during both conditions are middle frontal (left dorsolateral middle frontal cortex) and right SMG. The results correspond to the fact that listening to “OM” sound recruits neural systems implicated in emotional empathy.  相似文献
