The present study examined whether cinematographic editing density affects viewers’ perception of time. As a second aim, based on embodied models that conceive time perception as strictly connected to the movement, we tested the hypothesis that the editing density of moving images also affects viewers’ eye movements and that these later mediate the effect of editing density on viewers’ temporal judgments. Seventy participants watched nine video clips edited by manipulating the number of cuts (slow- and fast-paced editing against a master shot, unedited condition). For each editing density, multiple video clips were created, representing three different kinds of routine actions. The participants’ eye movements were recorded while watching the video, and the participants were asked to report duration judgments and subjective passage of time judgments after watching each clip. The results showed that participants subjectively perceived that time flew more while watching fast-paced edited videos than slow-paced or unedited videos; by contrast, concerning duration judgments, participants overestimated the duration of fast-paced videos compared to the master-shot videos. Both the slow- and the fast-paced editing generated shorter fixations than the master shot, and the fast-paced editing led to shorter fixations than the slow-paced editing. Finally, compared to the unedited condition, editing led to an overestimation of durations through increased eye mobility. These findings suggest that the editing density of moving images by increasing the number of cuts effectively altered viewers’ experience of time and add further evidence to prior research showing that performed eye movement is associated with temporal judgments. 相似文献

The subjective feeling of free choice is an important feature of human experience. Experimental tasks have typically studied free choice by contrasting free and instructed selection of response alternatives. These tasks have been criticised, and it remains unclear how they relate to the subjective feeling of freely choosing. We replicated previous findings of the fMRI correlates of free choice, defined objectively. We introduced a novel task in which participants could experience and report a graded sense of free choice. BOLD responses for conditions subjectively experienced as free identified a postcentral area distinct from the areas typically considered to be involved in free action. Thus, the brain correlates of subjective feeling of free action were not directly related to any established brain correlates of objectively-defined free action. Our results call into question traditional assumptions about the relation between subjective experience of choosing and activity in the brain’s so-called voluntary motor areas. 相似文献

Over the past 9 years approximately 2 million U.S. military personnel have deployed in support of Operation Iraqi Freedom
in Iraq and Operation Enduring Freedom in and around Afghanistan. It has been estimated that 5–17% of service members returning
from these deployments are at significant risk for combat-related posttraumatic stress disorder (PTSD). Many of these returning
war veterans will seek medical and mental health care in academic health centers. This paper reviews the unique stressors
that are related to the development of combat-related PTSD. It also reviews evidence-based approaches to the assessment and
treatment of PTSD, research needed to evaluate treatments for combat-related PTSD, and opportunities and challenges for clinical
psychologists working in academic health centers. 相似文献

Models of decision making postulate that interactions between contextual conditions and characteristics of the decision maker determine decision-making performance. We tested this assumption by using a possible positive contextual influence (goals) and a possible negative contextual influence (anchor) in a risky decision-making task (Game of Dice Task, GDT). In this task, making advantageous choices is well known to be closely related to a specific decision maker variable: the individual level of executive functions. One hundred subjects played the GDT in one of four conditions: with self-set goal for final balance (n?=?25), with presentation of an anchor (a fictitious Top 10 list, showing high gains of other participants; n?=?25), with anchor and goal definition (n?=?25), and with neither anchor nor goal setting (n?=?25). Subjects in the conditions with anchor made more risky decisions irrespective of the negative feedback, but this anchor effect was influenced by goal monitoring and moderated by the level of the subjects' executive functions. The findings imply that impacts of situational influences on decision making as they frequently occur in real life depend upon the individual's cognitive abilities. Anchor effects can be overcome by subjects with good cognitive abilities. 相似文献

What Mamardašvili meant by “process of knowledge” is not an all-embracing vision of reality accomplished “once-and-for-all”;
it is not a step by step procedure of deduction; rather it is an anti-dialectical reconstruction of a constellation of signs
put together over and over again by the subject by an act of non-premeditated genius. It is a kind of aesthetic act that makes
the sense appear, like a vertical cut in the sequential line of space and time. 相似文献

In response to Schmidt, Le, and Ilies' (2003) call for further assessment of transient error variance in measures of key individual difference variables, the current study examines transient error estimates for eight speeded cognitive ability scales and a composite scale. One hundred twenty‐three participants were tested on two occasions with a 1‐week interval between administrations. Estimates of transient error ranged from a low of .01 to a high of .18, with an average value of .09. The coefficient of equivalence, based on the split‐half method, resulted in overestimates of reliability by as little as 1.90% to as much as 25.96%, with an average 12.96%. 相似文献

Self-report and mono-method bias often threaten the validity of research conducted in business settings and thus hinder the development of theories of organizational behavior. This paper outlines a conceptual framework for understanding factors that influence the motivation of an employee to bias his or her responses to questions posed by organizational researchers. Using a longitudinal, multitrait-multimethod dataset, we illustrate various aspects of the problem and argue that traditional approaches for controlling self-report bias do not adequately prevent the problem. The results suggest the need for developing a theory of method effects and companion analytic techniques to improve the accuracy of psychological research in business settings. 相似文献

Siddha Samadhi Yoga is a program in which meditation is associated with pranayama (breathing exercises). 22 volunteers with anxiety complaints (M age = 42.8 yr., SD = 10.3) were assigned to two groups: 14 attended the yoga group, and 8 attended a waiting-list or control group. They were evaluated before the intervention and 1 month after it on the State-Trait Anxiety Inventory, the Beck Depression Inventory, Tension Feelings Self-evaluation Scales, and the Well-being Self-evaluation Scales. A significant reduction in scores on anxiety, depression, and tension was found in yoga group, as well as an increase in well-being in comparison with the control group. 相似文献

This study assessed the influence of clinical and socio-demographic variables on the psychological adaptation of transplanted
adolescents. Twenty-six transplanted adolescents and 25 healthy adolescents, aged 13–17, and their parents participated in
the study. The following domains were measured: social competence, emotional/behavioral problems, self-concept, self-esteem
and subjective well-being. The findings revealed that transplanted boys presented significantly less social competence (U = 26,000, p < .05) and more externalizing problems (U = 25,000, p < .05), social problems (U = 25,000, p < .05) and attention problems (U = 17,500, p < .01) than healthy boys. In contrast, transplanted girls displayed significantly more internalizing problems (U = 47,000, p < .05) and lower physical self-concept (U = 49,500, p < .05) than healthy girls. Hierarchical regression analysis showed clinical variables, especially waiting-list time, significantly
predicted attention problems (β = .364, p < .05) and negative affect (β = .632, p < .05) in transplanted adolescents. Also, male (β = −0.554, p < .01) and younger (β = −0.444, p < .01) transplanted adolescents were at risk for attention problems. Our data suggest the importance of the waiting-list time
for transplanted adolescents. Efforts to reduce the pretransplant phase would help adolescents achieve better psychological
adaptation at long-term posttransplant. 相似文献

Conditioned reinforcers, or tokens, are frequently used in clinical settings; however, little applied research has focused on establishing and validating their effectiveness. Following pairing of a novel token with an edible reinforcer in the present study, preference and reinforcer assessments verified that the tokens functioned as conditioned reinforcers. Results indicated that the tokens were established as conditioned reinforcers that matched the reinforcer value of the primary reinforcers with which they had been paired. The effects of motivating operations (MOs) on the effectiveness of these conditioned reinforcers were then evaluated. Conditioned reinforcer effectiveness decreased during satiation conditions. Subsequently it was found that increasing the number of backup reinforcers with which the token was paired resulted in the effectiveness maintaining during satiation conditions.
