This study examined the lexical representations and psycholinguistic mechanisms underlying the production and recognition of novel words with two pronunciation variants in French. Participants first learned novel schwa words (e.g., /??nyk/), which varied in their alternating status (i.e., whether these words were learned with one or two variants) and, for alternating words, in the frequency of their variants. They were then tested in picture-naming (free or induced) and recognition memory tasks (i.e., deciding whether spoken items were learned during the experiment or not). Results for free naming show an influence of variant frequency on responses, more frequent variants being produced more often. Moreover, our data show an effect of the alternating status of the novel words on naming latencies, with longer latencies for alternating than for nonalternating novel words. These induced naming results suggest that both variants are stored as lexical entries and compete during the lexeme selection process. Results for recognition show an effect of variant frequency on reaction times and no effect of variant type (i.e., schwa versus reduced variant). Taken together, our findings suggest that participants both comprehend and produce novel French schwa words using two lexical representations, one for each variant. 相似文献

Search performance is sequence-dependent. A specific finding observed in compound-search tasks consists of an interaction between cross-trial sequences (repetition vs. change) of the target-defining (primary) and response-defining (secondary) features: The effect of a target change is greater when the response stays the same than when the response changes. The present study tested whether this interaction arises from processes involved in target search or from later processes in compound tasks. Uncertainty about the upcoming target location??that is, the search component of compound tasks??was removed in different experiments, either by the use of exogenous spatial precues or by presenting only one, central item. Despite having removed the search component, we observed a robust interaction between target (primary) and response (secondary) feature sequences. These results suggest that this interaction originates from a processing stage concerned with discriminating the response feature of a single (selected) item, rather than from a search-related stage. Furthermore, the results support our multiple-weighting-systems hypothesis, according to which sequence effects in visual search tasks do not stem from a single, unitary mechanism; rather, multiple stages of processing on any given trial can lead to separate memory traces, which in turn have effects on different stages of processing on the subsequent trial. 相似文献

Background sounds, such as narration, music with prominent staccato passages, and office noise impair verbal short-term memory even when these sounds are irrelevant. This irrelevant sound effect (ISE) is evoked by so-called changing-state sounds that are characterized by a distinct temporal structure with varying successive auditory-perceptive tokens. However, because of the absence of an appropriate psychoacoustically based instrumental measure, the disturbing impact of a given speech or nonspeech sound could not be predicted until now, but necessitated behavioral testing. Our database for parametric modeling of the ISE included approximately 40 background sounds (e.g., speech, music, tone sequences, office noise, traffic noise) and corresponding performance data that was collected from 70 behavioral measurements of verbal short-term memory. The hearing sensation fluctuation strength was chosen to model the ISE and describes the percept of fluctuations when listening to slowly modulated sounds (f(mod) < 20?Hz). On the basis of the fluctuation strength of background sounds, the algorithm estimated behavioral performance data in 63 of 70 cases within the interquartile ranges. In particular, all real-world sounds were modeled adequately, whereas the algorithm overestimated the (non-)disturbance impact of synthetic steady-state sounds that were constituted by a repeated vowel or tone. Implications of the algorithm's strengths and prediction errors are discussed. 相似文献

Abstract The existence of man is distinguished by its split state: man stands in the middle of life yet still has an awareness of his own death. He has to compensate whatever is missing in him naturally at the societal level, created as culture, and at the individual level through creativity. Rank investigated the human ‘creative drive’, the anthropological aspiration to express oneself in creative works, and to overcome the fear of death with its help. Freud admired poets and artists, whose achievements he could not psychoanalytically access, but he considered science superior to the harmless and naïve arts. There are two anthropological radicals: premature birth and the consciousness of death. Freud's massive fear of death made it difficult for him to acknowledge the problem of death appropriately. In Rank's concept, the development of human creativity contributes towards the fear of death being alleviated so that the knowledge of death can be integrated into life; creativity belongs to the fundamental opportunities of man that may enable him to find a way through neurosis. Failure is as much a part of life as is creativity: those who do not experience and accept life in its tragic dimension are denied creativity. Only a creative person who accepts his partial failure finds the strength to continue to be creative without his imperfect work leading to the ritual repetition of the same thing again and again, that is, getting stuck in recidivism. 相似文献

Objective: Previous research on illness perceptions has focused on single illnesses, but most adults over 65 suffer from multiple illnesses (multimorbidity). This study tests three competing operationalisations of multiple illness perceptions in predicting physical functioning and adherence: (1) main effects and interactions model; (2) peak model with effects of the most prominent illness perception; and (3) combined model with averaged illness perceptions over multiple illnesses.Design: Longitudinal study in N?=?215 individuals (65–86?years) with multimorbidity at two measurement points over six months. Participants filled in two Brief Illness Perception Questionnaires (B-IPQ) on their two most severe illnesses.Main outcome measures: Physical functioning, medication adherence.Results: Factor analyses suggest that the B-IPQ contains three dimensions; consequences, control and timeline. Multiple regression models fit the data best for (1) and (3). Timeline (β?=??.18) and control (β?=?.21) predict adherence in (1); consequences (β?=?.16) and control (β?=?.20) in (3). Physical functioning was significantly predicted by interacting control beliefs in (1; β?=?.13), by peak consequences in (2; β?=??.14) and by consequences (β?=??.15) in (3).Conclusions: Individuals with multimorbidity hold both distinct and combined perceptions about their illnesses. To understand individual responses to multimorbidity, perceptions about all illnesses and multimorbidity as entity should be examined. 相似文献

Objectives: Subjective age is an important correlate of health, well-being, and longevity. So far, little is known about short-term variability in subjective age and the circumstances under which individuals feel younger/older in daily life. This study examined whether (a) older adults’ felt age fluctuates on a day-to-day basis, (b) daily changes in health, stressors, and affect explain fluctuations in felt age, and (c) the daily associations between felt age and health, stressors, or affect are time-ordered.Method: Using an eight-day daily diary approach, N = 43 adults (60–96 years, M = 74.65, SD = 8.19) filled out daily questionnaires assessing subjective age, health, daily stressors, and affect. Data were analysed using multilevel modelling.Main outcome measures: Subjective age, health, daily stressors, affect.Results: Intra-individual variability in felt age was not explained by time but by short-term variability in other variables. Specifically, on days when participants experienced more than average health problems, stress, or negative affect they felt older than on days with average health, stress, or negative affect. No time-ordered effects were found.Conclusion: Bad health, many stressors, and negative affective experiences constitute circumstances under which older adults feel older than they typically do. Thus, daily measures of subjective age could be markers of health and well-being. 相似文献

Background
The restructuring of the European educational system in line with the Bologna process forms a source of complaints in German universities because of the rigid structure of the curricula and higher pressure to perform. By comparison of students in the former diploma system with students in the bachelor master system during the period of restructuring it was analyzed if the changes in the educational system affect psychological distress in a negative way.Methods
The analysis of 535 datasets from the psychotherapeutic outpatient department for students of the university Göttingen in the years between 2006 and 2010 was carried out to clarify if students in the bachelor master system suffered more from severe psychological distress than students of the former German diploma system. Dependent variables are a questionnaire comprising current problems and the global severity index (GSI) from the symptom checklist (SCL)-90-R. The confounding factors resulting from course of study and stud -time in the period of the restructuring have been controlled.Results
The bachelor master students who sought help were not generally suffering from more psychological distress than diploma students. However, in comparison to students from the former diploma system they suffered more from psychological distress and problems resulting from the study situation and organization in the first semesters.Conclusions
Psychotherapeutic university outpatient departments have to be aware of the changing demand. The study organization has to be changed to be more student friendly, especially in the beginning. An adequate infrastructure for psychotherapeutic university outpatients has to be provided. 相似文献949.

ABSTRACTCopper-mould-cast Al–Cu–Ni alloys show adjacent coexistence of in situ grown ordered and eutectic phases. A bimodal microstructure of α–Al and eutectic α-Al+θ-Al2Cu phases with length-scale hierarchy evolves during solidification. Microstructural analysis through Transmission Electron Microscopy (TEM) and Scanning Electron Microscopy (SEM) shows the presence of Vacancy-ordered phases (VOPs) with different morphologies in two different compositions. 相似文献

The psychoanalyst Luise Meyer documents the inextricable entanglement of the inner and outer world in post-war Germany. With the assistance of psychoanalysis she hoped to find inner peace and a social niche which allowed a professional development. 相似文献
