This explorative content-analytic study completes earlier studies on the lifespan distributions of number and affect of past and future life-events, collected by means of the Life-line Interview Method (LIM), for three age groups of men and women (young, middle and late adulthood). LIM events were classified into 40 subcategories divided over 9 categories: Relations, School, Work, Health, Growth, Home, Birth, Death and Other. Compression of the full data set by age group, gender, affect, decade, and time perspective, disclosed various patterns of events underlying the human life-course, e.g., the 'bump,' 'rosy view' and 'gender phase contrast' patterns. The compressed data set provided detailed material for the composition of three written group portraits of life, reflecting the modal life story of young, middle-aged and older men and women. Patterns and portraits show a content shift of past memories and future expectations over the lifespan, supporting a more dynamic view on the human life-course.  相似文献

Within alphabetic languages, spelling-to-sound consistency can differ dramatically. For example, English and German are very similar in their phonological and orthographic structure but not in their consistency. In English the letter a is pronounced differently in the words bank, ball, and park, whereas in German the letter a always has the same pronunciation (e.g., Ball, Park, Bank). It is often argued that reading acquisition has a reciprocal effect on phonological awareness. As reading is acquired, therefore, spoken language representation may be affected differently for English and German children. Prior to literacy acquisition, however, phonological representation in English and German children should be similar due to the similar phonological structure of the two languages. We explored this hypothesis by comparing phonological awareness at the rime and phoneme levels in prereaders and beginning readers in English and German. Similar developmental effects were indeed observed in prereaders, but differential effects had emerged within the first year of reading instruction.  相似文献

This study assesses the optimal cut-off point for the Impact of Event Scale and compares its screening properties with those of the Self-rating Inventory for Posttraumatic Stress Disorder among war-related trauma victims. 74 patients with war-related trauma were administered the Impact of Event Scale and the Self-rating Inventory for Posttraumatic Stress Disorder, followed 1 wk. later by the Clinician-administered PTSD Scale. Receiver operating characteristic analysis indicated for the Impact of Event Scale a sensitivity of .77 and a specificity of .51 at a cut-off value of 36. For the Self-rating Inventory for Posttraumatic Stress Disorder a sensitivity of .86 and a specificity of .69 were found at a cut-off value of 52. The authors conclude that careful use of the Impact of Event Scale as a screening measure for Posttraumatic Stress Disorder is warranted.  相似文献

We argue, from an ethology-inspired perspective, that the internal concepts 'surface colours' and 'illumination colours' are part of the data format of two different representational primitives. Thus, the internal concept of 'colour' is not a unitary one but rather refers to two different types of 'data structure', each with its own proprietary types of parameters and relations. The relation of these representational structures is modulated by a class of parameterised transformations whose effects are mirrored in the idealised computational achievements of illumination invariance of colour codes, on the one hand, and scene invariance, on the other hand. Because the same characteristics of a light array reaching the eye can be physically produced in many different ways, the visual system, then, has to make an 'inference' whether a chromatic deviation of the space-averaged colour codes from the neutral point is due to a 'non-normal', ie chromatic, illumination or due to an imbalanced spectral reflectance composition. We provide evidence that the visual system uses second-order statistics of chromatic codes of a single view of a scene in order to modulate corresponding transformations. In our experiments we used centre surround configurations with inhomogeneous surrounds given by a random structure of overlapping circles, referred to as Seurat configurations. Each family of surrounds has a fixed space-average of colour codes, but differs with respect to the covariance matrix of colour codes of pixels that defines the chromatic variance along some chromatic axis and the covariance between luminance and chromatic channels. We found that dominant wavelengths of red-green equilibrium settings of the infield exhibited a stable and strong dependence on the chromatic variance of the surround. High variances resulted in a tendency towards 'scene invariance', low variances in a tendency towards 'illumination invariance' of the infield.  相似文献

ABSTRACT

Recent studies have found that digital games can be used to improve the players’ mood, especially after emotionally unpleasant experiences. We introduce competence repair as an extension of previous work on mood repair. To investigate the effects of digital games on both mood and competence repair, we conducted 3 studies using quiz games. In the quasi-experimental Study 1 (N = 143), we manipulated the necessity for repair via a false feedback task (positive vs. negative), and looked at the impact of in-game success (victory vs. defeat). In the experimental Studies 2 (N = 91) and 3 (N = 109), we aimed at conceptually replicating and extending the findings on the impact of in-game success by varying participants’ success over a series of 4 matches (Study 2: close game outcomes, Study 3: clear victory/defeat). The results of these studies indicate that the efficacy of digital games for mood repair, as well as competence repair, depends on the necessity for repair, as well as success in the game. However, competence repair occurred even after participants were defeated repeatedly in a series of close matches. These results are discussed in light of the potential of digital games for fulfilling (previously thwarted) psychological needs.  相似文献

Applying the Needs‐Based Model of Reconciliation to contexts of group disparity, two studies examined how messages from outgroup representatives that affirmed the warmth or competence of advantaged or disadvantaged groups influenced their members' intergroup attitudes. Study 1 involved natural groups differing in status; Study 2 experimentally manipulated status. In both studies, advantaged‐group members responded more favorably, reporting more positive outgroup attitudes and willingness to change the status quo toward equality, to messages reassuring their group's warmth. Disadvantaged‐group members responded more favorably to messages affirming their group's competence. Study 2 further demonstrated that the effectiveness of reassuring a disadvantaged group's competence stemmed from restoring its threatened dimension of identity, irrespective of a change of the status quo. In line with Social Identity Theory (Tajfel & Turner, 1979), these results indicate that beyond the competition over tangible resources, groups are concerned with restoring threatened dimensions of their identities. Exchanging messages that remove identity‐related threats may promote not only positive intergroup attitudes but also greater willingness to act collectively for intergroup equality.

Abstract

Considerable attention has been devoted recently to changes in the psychological contract and the implications for HRM. However, much of our understanding of both the socio-cognitive processes involved in the contracting process and the ability of national HRM systems to accommodate the new demands of psychological contracting is accultural or unicultural. This article reviews the content, process, and context of changes in the contract within Europe. A model of the relationship between national culture and other cross-national factors and the process of contracting is developed.  相似文献

A study of 494 employees nested in workgroups from 19 different organizations revealed group identification to be an important factor influencing work-related bullying at both the individual and the group level. Results show that the more employees identified with their group, the less likely they were victims of bullying, which is in line with previous social identity-based analyses of work stress. More importantly, the higher the average level of group identification in the organization, the lower the odds of being a victim versus not being a victim. The latter effect constituted a genuine context effect. These findings redress a neglect of the social bases of workplace bullying and suggest that bullying needs to be understood within a broader perspective of workgroup identities.  相似文献

Theory of Mind (ToM) is the ability to infer other people’s mental states like intentions or desires. ToM can be differentiated into affective (i.e., recognizing the feelings of another person) and cognitive (i.e., inferring the mental state of the counterpart) subcomponents. Recently, subcortical structures such as the basal ganglia (BG) have also been ascribed to the multifaceted concept ToM and most BG disorders have been reported to elicit ToM deficits. In order to assess both the correlates of affective and cognitive ToM as well as involvement of the basal ganglia, 30 healthy participants underwent event-related fMRI scanning, neuropsychological testing, and filled in questionnaires concerning different aspects of ToM and empathy. Directly contrasting affective (aff) as well as cognitive (cog) ToM to the control (phy) condition, activation was found in classical ToM regions, namely parts of the temporal lobe including the superior temporal sulcus, the supplementary motor area, and parietal structures in the right hemisphere. The contrast aff > phy yielded additional activation in the orbitofrontal cortex on the right and the cingulate cortex, the precentral and inferior frontal gyrus and the cerebellum on the left. The right BG were recruited in this contrast as well. The direct contrast aff > cog showed activation in the temporoparietal junction and the cingulate cortex on the right as well as in the left supplementary motor area. The reverse contrast cog > aff however did not yield any significant clusters. In summary, affective and cognitive ToM partly share neural correlates but can also be differentiated anatomically. Furthermore, the BG are involved in affective ToM and thus their contribution is discussed as possibly providing a motor component of simulation processes, particularly in affective ToM.  相似文献

Abstract

Recognition and cued recall of ordinary action phrases (e.g. “open the book”) and bizarre ones (e.g. “plant the hammer”) were compared under two encoding conditions: in verbal tasks (VTs), subjects learned the phrases by simply listening to them; in subject-performed tasks (SPTs), subjects learned the phrases by performing the denoted actions (without real objects). Memory performance was better after SPTs than after VTs in recognition and cued recall. In addition to this already established finding, it was observed that recognition was better for bizarre phrases than for ordinary ones after VTs and that bizarreness was unrelated to recognition after SPTs. Cued recall, on the other hand, depended on bizarreness after VTs as well as after SPTs and, in contrast to the recognition findings, ordinary phrases were recalled better than bizarre phrases. This pattern of findings was explained by the assumptions that lexical and conceptual information is encoded after VTs and motor information is additionally encoded after SPTs, and that different kinds of information are used in recognition and cued recall, and after VTs and SPTs.  相似文献
