The aim of the present study was to investigate the effects of social intentions on action. Participants (N=13) were requested to reach towards, grasp an object, and either pass it to another person (social condition) or put it on a concave base (single-agent condition). Movements' kinematics was recorded using a three-dimensional motion analysis system. The results indicate that kinematics is sensitive to social intention. Movements performed for the 'social' condition were characterized by a kinematic pattern which differed from those obtained for the 'single-agent' condition. Results are discussed in terms of a motor simulation hypothesis, which assumes that the same mechanisms underlying motor intention are sensitive to social intentions. 相似文献

This study investigates how stereoscopy (the illusion of depth and 3D imaging) affects the sense of presence and the intensity of the positive mood that users feel in virtual environments (VEs). A between-group design was used, and 40 volunteers were randomly assigned to one of two experimental conditions (stereoscopy vs. no stereoscopy) and to one of two emotional VEs (relaxation or joy). The participants' emotions were assessed before and after the VR experience. Presence was measured with two postexperiment questionnaires (ITC-SOPI and SUS). Results show that there were no differences between stereoscopic and monoscopic presentations in VEs (neither subjective sense of presence nor emotional reactions). Practical and theoretical implications of these findings are discussed herein. 相似文献

Considering that the intersexual condition has a negative impact on the individual, their family, and society, health professionals and researchers have dedicated themselves to is to describe and understand the perceptions of primary caregivers regarding intersexuality and its developmental aspects. Six mothers and one grandmother of school age children were interviewed. The data indicated that living with the stigma of intersexuality can mean a permanent state of crisis within the family system. Issues such as guilt about the child's suffering and questions related to the choice of gender follow the family from the moment of diagnosis. It is suggested that the therapeutic follow-up should foster the necessary conditions for the family group to be organized as a model of competence, replacing the model of guilt. 相似文献

This study examines children's comprehension of non‐essential counting features (conventional rules). The objective of the study was to determine whether the presence or absence of cardinal values in pseudoerrors and the type of conventional rule violated affects children's performance. A detection task with pseudoerrors was presented through a computer game to 146 primary school children in grades 2 through 4. The same pseudoerrors were presented both with and without cardinal values; the pseudoerrors violated conventional rules of spatial adjacency, temporal adjacency, spatial–temporal adjacency, and left‐to‐right direction. Half of the participants within each age group were randomly assigned to an experimental condition that included pseudoerrors with a cardinal value, and the other half were assigned to a condition that included pseudoerrors without a cardinal value. The results show that when presented with a cardinal value, children more easily recognize the optional nature of non‐essential counting features. Likewise, the type of conventional rule transgressed significantly affected the children's acceptance of pseudoerrors as valid counts. Participants penalized breaches of temporal and spatial–temporal adjacency to a greater degree than breaches of spatial adjacency and left‐to‐right direction. 相似文献

Our goal was to assess the role of timing in pigeons' performance in the midsession reversal task. In discrete-trial sessions, pigeons learned to discriminate between 2 stimuli, S1 and S2. Choices of S1 were reinforced only in the first half of the session and choices of S2 were reinforced only in the second half. Typically, pigeons choose S2 before the contingency reverses (anticipatory errors) and S1 after (perseverative errors), suggesting that they time the interval from the beginning of the session to the contingency reversal. To test this hypothesis, we exposed pigeons to a midsession reversal task and, depending on the group, either increased or decreased the ITI duration. We then contrasted the pigeons' performance with the predictions of the Learning-to-Time (LeT) model: In both conditions, preference was expected to reverse at the same time as in the previous sessions. When the ITI was doubled, pigeons' preference reversal occurred at half the trial number but at the same time as in the previous sessions. When the ITI was halved, pigeons' preference reversal occurred at a later trial but at an earlier time than in the previous sessions. Hence, pigeons' performance was only partially consistent with the predictions of LeT, suggesting that besides timing, other sources of control, such as the outcome of previous trials, seem to influence choice. 相似文献

Seventy-five left and right brain-damaged patients, with or without hemispatial neglect, and 40 age-matched control subjects were tested on cancellation tasks with two different visual textures modeled after Julesz (1981). In one condition (“preattentive”), target elements segregated easily from background elements and were perceived effortlessly. In the other (“attentive”), target elements did not segregate easily and could be detected only after prolonged focal scrutiny. Both controls and patients were more accurate and faster on the preattentive than attentive texture. However, only neglect patients were disproportionately impaired on the attentive texture, thus suggesting that unilateral neglect is exacerbated by the low visual salience of the stimuli and a higher engagement of focal attention. Thus, a simple bedside test may help to tell apart the level of visual information processing maximally impaired in neglect patients. 相似文献

This paper aims to highlight four major points: first: a ‘Jungian attitude’ understood as a viewpoint which enables work with interconnectedness through various fields of knowledge. Second, that complexes are dynamic, as is memory, and that both are transformed by experience and develop hand in hand with each other i.e., the transformation of the complex occurs through the transformation of memory as embodied in internal working models, and vice versa. Third, complexes and archetypes are linked to each other in matrices of one form or another and lead to the complexity of the psyche, which is a developing system. Fourth, the analytical process provides an arena that enables and consolidates interconnections that foster a better intrapsychic transition. The analytic meeting promotes profound changes, redesigning our neural architecture as well as our psychic landscape. 相似文献
