The accessibility of concepts related to justice and injustice is proposed as a basic cognitive mechanism underlying the personality trait of justice sensitivity. To provide evidence for this assertion, the manner in which justice sensitivity shapes the interpretation of an ambiguous situation was investigated. It was found that, without priming, and after injustice is primed, persons high in justice sensitivity tend to perceive greater injustice in an ambiguous situation than persons low in justice sensitivity. If the restoration of justice is primed, however, persons high in justice sensitivity tend to interpret the ambiguous situation as more just when compared to persons low in justice sensitivity. Results are discussed with regard to a process‐oriented explanation of emotional and behavioural effects of justice sensitivity. 相似文献

To what extent can individuals gain insight into their own or another person's implicit dispositions' We investigated whether self‐perceivers versus neutral observers can detect implicit dispositions from nonverbal behavioural cues contained in video feedback (cue validity) and whether these cues are in turn used as a valid basis for explicit dispositional inferences (cue utilization). Across three studies in the domains of extraversion and anxiety we consistently obtained reliable cue validity and cue utilization for neutral observers but not for self‐perceivers. An additional measure of state inferences in Study 3 showed that one reason for the lack of mediation in self‐perceivers is their reluctance to use their state inferences as a basis for more general trait inferences. We conclude that people have a ‘blind spot’ with respect to the nonverbal behavioural manifestations of their unconscious selves, even though neutral observers may readily detect and utilize this information for dispositional inferences.

Sudden changes of visual stimulation attract attention. The observer's body motion generates retinal-flow field patterns containing information about his/her own speed and trajectory and relative motion of other objects. We investigated the effectiveness of relative motion as an attentional cue and compared it with conventional cueing by appearance of a frame in the far periphery of the visual field. In a group of ten subjects, contrast thresholds for the perception of static Gabor grating orientation [four alternative non-forced-choice (4ANFC)] task were determined at 20 degrees, 30 degrees, 40 degrees, and 60 degrees eccentricity. Subsequently, near-threshold discrimination performance of Gabor pattern orientation without versus with a ring-shaped cue was measured at the same positions. The same Gabor patterns were then presented embedded in a random-dot flow field, and uncued discrimination performance was compared with performance after presentation of a relative-motion cue (RMC), ie a small random-dot field with motion in the opposite direction of the flow field. Both the conventional ring cue and the RMC induced significantly increased discrimination performance at all test locations. With the parameters chosen for this study, the RMC was slightly less effective than the conventional cue, but its effects were somewhat more pronounced in the far periphery of the visual field. Thus, relative motion is a powerful cue to attract attention to peripheral visual objects and improves performance as effectively as a conventional ring cue. The findings have practical relevance for everyday life, in particular for tasks like driving and navigation. 相似文献

This study examines the life course of 2 independent components of adult affective development, 1 aimed at differentiation and complexity, the other aimed at optimization and positive emotional balance. These 2 components are predicted to have different developmental trajectories over the adult life span and to become related in a compensatory fashion under conditions of resource restrictions, such as those related to late life. Using individual growth curve estimation, we modeled 6-year longitudinal changes in the 2 components in a total sample of 388 individuals ranging in age from 15 to 88 years. As predicted, initial level of affect optimization was positively associated with age up to late middle age with a subsequent leveling off; individual rates of change were found to decelerate with age up to age 60 years and accelerate again around age 80 years. For affect complexity, initial level of affect complexity was positively associated with age up to age 45 years and negatively associated with age from then on, whereas individual rates of change were negatively associated with age, and this association tended to get stronger with age. 相似文献

Initial psychometric properties of the experiences questionnaire: validation of a self-report measure of decentering 总被引:1,自引:1,他引:0

Decentering is defined as the ability to observe one's thoughts and feelings as temporary, objective events in the mind, as opposed to reflections of the self that are necessarily true. The Experiences Questionnaire (EQ) was designed to measure both decentering and rumination but has not been empirically validated. The current study investigated the factor structure of the EQ in both undergraduate and clinical populations. A single, unifactorial decentering construct emerged using 2 undergraduate samples. The convergent and discriminant validity of this decentering factor was demonstrated in negative relationships with measures of depression symptoms, depressive rumination, experiential avoidance, and emotion regulation. Finally, the factor structure of the EQ was replicated in a clinical sample of individuals in remission from depression, and the decentering factor evidenced a negative relationship to concurrent levels of depression symptoms. Findings from this series of studies offer initial support for the EQ as a measure of decentering. 相似文献

Regular physical exercise improves cognitive functions and lowers the risk for age-related cognitive decline. Since little is known about the nature and the timing of the underlying mechanisms, we probed whether exercise also has immediate beneficial effects on cognition. Learning performance was assessed directly after high impact anaerobic sprints, low impact aerobic running, or a period of rest in 27 healthy subjects in a randomized cross-over design. Dependent variables comprised learning speed as well as immediate (1 week) and long-term (>8 months) overall success in acquiring a novel vocabulary. Peripheral levels of brain-derived neurotrophic factor (BDNF) and catecholamines (dopamine, epinephrine, norepinephrine) were assessed prior to and after the interventions as well as after learning. We found that vocabulary learning was 20 percent faster after intense physical exercise as compared to the other two conditions. This condition also elicited the strongest increases in BDNF and catecholamine levels. More sustained BDNF levels during learning after intense exercise were related to better short-term learning success, whereas absolute dopamine and epinephrine levels were related to better intermediate (dopamine) and long-term (epinephrine) retentions of the novel vocabulary. Thus, BDNF and two of the catecholamines seem to be mediators by which physical exercise improves learning. 相似文献

This study tested an internalization model of emotional development proposing that emotional expression decreases during childhood in situations in which emotions serve only self-regulation. This model was tested by inducing joy and disappointment in solitary versus interpersonal conditions in 3 gender-matched, 20-member groups of 6-, 7-, and 8-year-olds. Results supported the model: Expression--but not self-reported feeling--decreased in solitary conditions as a function of increasing age, whereas both expression and feeling remained stable in the interpersonal condition. This effect also correlated positively with the ability to discriminate between expression and feeling on a conceptual level. Results are discussed in relation to the major developmental trend toward creating a mental level of self-regulation--first described by Vygotsky. 相似文献

The purpose of this study was to reveal underlying processes in adoptive kinship networks that experienced increases or decreases in levels of openness during the child's adolescent years. Intensive case study analyses were conducted for 8 adoptive kinship networks (each including an adoptive mother, adoptive father, adopted adolescent, and birth mother), half of whom had experienced an increase in openness from indirect (mediated) to direct (fully disclosed) contact and half of whom had ceased indirect contact between Waves 1 and 2 of a longitudinal study. Adoptive mothers tended to be more involved in contact with the birth mother than were adoptive fathers or adopted adolescents. Members of adoptive kinship networks in which a decrease in level of contact took place had incongruent perspectives about who initiated the stop in contact and why the stop took place. Birth mothers were less satisfied with their degree of contact than were adoptive parents. Adults' satisfaction with contact was related to feelings of control over type and amount of interactions and permeability of family boundaries. In all adoptive kinship networks, responsibility for contact had shifted toward the adopted adolescent regardless of whether the adolescent was aware of this change in responsibility. 相似文献

Schizophrenia, like other pathological conditions of mental life, has not been systematically included in the general study of consciousness. By focusing on aspects of chronic schizophrenia, we attempt to remedy this omission. Basic components of Husserl’s phenomenology (intentionality, synthesis, constitution, epoche, and unbuilding) are explicated and then employed in an account of chronic schizophrenia. In schizophrenic experience, basic constituents of reality are lost and the subject must try to explicitly re-constitute them. “Automatic mental life” is weakened such that much of the world that is normally taken-for-granted cannot continue to be so. The subject must actively re-lay the ontological foundations of reality. 相似文献
