The accuracy of the recidivism risk assessment instruments Static-99 and Stable-2007 for sexual offenders was examined in a population of released male forensic sexual offenders hospitalized under mandatory treatment in Austria (N?=?96). The Static-99 with an area under the curve (AUC) ?value of 0.86 and the Stable-2007 (AUC?=?0.71) were significantly related to sexual reoffending after nearly 7 years time at risk, thus revealing a predictive power comparable with offenders released from prison (N?=?274). Also the Stable-2007 incrementally supplemented the predictive accuracy of the Static-99. Static-99/Stable-2007 risk/need categories identified a high risk group with a 50?% chance for sexual reconviction within 5 years after release despite a favorable risk assessment as the precondition for release and post-release risk management. On the other hand, there was virtually no relapse in the three lowest risk categories suggesting a specific effect of the mandatory treatment at least in these offender categories. The data suggest that the instruments are valid not only for offenders released from prison but also for forensic sexual offenders. 相似文献

This study examines the interplay of unemployment stress, trait anxiety and physical exercise in the development of physical health. Longitudinal data were taken from a sample of East German migrants (N = 330) who were confronted with the potentially stressful demand of finding a job in the Western society. Unemployment stress was found to exert a main effect on illness level. Trait anxiety was a moderator of the stress-illness relationship, but exercise was not. As indicated by a three-way interaction involving exercise, anxiety, and stress, exercise was most beneficial among high-anxious subjects who were not exposed to unemployment stress. Results of this study suggest that exercise may not buffer the deleterious effects of stressful situational conditions (unemployment), but may effectively mitigate the health-damaging consequences of lacking personal resources, such as high dispositional anxiety. 相似文献

The purpose of the present study was to investigate whether the link that has been established between stuttering and linguistic stress in adolescents and adults (the so-called stress effect) can also be observed in childhood stuttering. To account for confounding variables, both within-word position and grammatical class were measured, because these factors covary with linguistic stress. Speech samples of 22 preschool children (mean time of 9 months since onset of stuttering) were analyzed. The relative stress of each syllable was rated and syllables were categorized into long and short stressed, unstressed, and intermediately stressed syllables. Results showed that 97.8% of stuttering events occurred on first syllables of words and 76.5% on the first sound of syllables, that means a clear word-initial effect. Stuttering frequency on first syllables of function words was 16.9% and significantly higher than the frequency of stuttered first syllables of content words (11.5%). In function words short stressed syllables and intermediately stressed syllables were stuttered more often than unstressed syllables. The analysis for individual disfluency types revealed that, for function words, stuttering on short stressed syllables was associated with prolongations and syllable repetitions. However, in intermediately stressed syllables stuttering coincided most often with one-syllable word repetitions. This differentiation of the stress effect may suggest different causal mechanisms underlying these disfluency types. Educational objectives: The reader will learn about and be able to: (1) describe how within-word position, grammatical class, and linguistic stress effect stuttering frequency in preschool children who stutter; (2) explain how the occurrence of individual disfluency types depends on linguistic stress; (3) discuss how patterns of adults and preschool children who stutter differ in regard to these aspects. 相似文献

The normal distribution is characterized in a measurement theoretic framework. The qualitative conditions guarantee that representations can be regarded as random variables. Additional axioms, also qualitative in the measurement sense, yield the normal. One characterization draws on a limit theorem. The main result derives the normal distribution from conjoint measurement axioms. This approach consists of formulating properties of a linear model as a component structure with error as one component. The normal distribution of errors is shown to be a consequence of the measurement theoretic assumptions. The possible impact of these results on statistical models is discussed.

In the present study in 20 healthy subjects, event-related potentials (ERPs) were used to investigate the identification of picture stimuli. Each of 36 landscape pictures and 36 scrambled pictures was presented by a tachistoscope repeatedly until the subject made an identification response. Presentation of one picture was finished after 12 exposures. On the average, landscapes were identified after 5.8 ± 0.4 exposures; identification responses to scrambles were always wrong and occurred after 11.8 ± 0.1 exposures. Latencies and amplitude measures were assessed for P2, P3, N400, and the slow wave (SW). Changes in P2 across stimulus presentations did not differ between landscapes and scrambles excluding this component from being indicative for the processing of stimulus meaning. Amplitude of P3 generally declined across presentations, but increased prior to identification for landscape pictures. N400 rapidly declined across presentations of landscapes, but less rapidly for scrambles. The SW increased across stimulus presentations. This increase was more pronounced for landscape than scrambled pictures. The pattern of ERP changes can be interpreted in a framework of a stepwise inhibition of spreading activation within semantic memory with progressing picture identification. 相似文献

The present research examined lie detection abilities of a rarely investigated group, namely offenders. Results of the studies conducted thus far indicated a better performance of offenders compared to non‐offenders when discriminating between true and false messages. With two new studies, we aimed at replicating offenders' superior abilities in the context of deception detection. Results of Study 1 (N = 76 males), in contrast, revealed that offenders were significantly worse at accurately classifying true and false messages compared to non‐offenders (students). Results of Study 2 (N = 175 males) revealed that offenders' discrimination performance was not significantly different compared to non‐offenders (clinic staff). An internal meta‐analysis yielded no significant difference between offenders and non‐offenders, questioning the generalizability of previous findings. 相似文献

The application of Internet-based interventions within stepped-care models raises the question of when patients should receive Internet-based treatment and when patients should receive face-to-face (FtF) treatment. To address this question, the patient perception and effects of working mechanisms were evaluated after brief psychotherapy for insomnia applying a mixed-methods approach. Treatment was either delivered through a text-based chat or it was delivered FtF. Almost half of the patients who received the chat-based treatment indicated that chat-based communication was appropriate for them when dealing with sleep difficulties, but that they would prefer FtF communication for more sensitive topics. Results from the therapists’ evaluations of working mechanisms yielded that these working mechanisms were more strongly associated with treatment outcome in the FtF condition than they were in the chat-based condition. To understand and to interpret the results, media richness theory may be a useful tool: More severely impaired patients and patients with more complex concerns may need more complex (richer) communication formats for treatment delivery. Such heuristics may help to better justify treatment recommendations and optimize media choice in Internet-based interventions, e.g., by defining moments when human interaction is needed and moments when communication could be conducted by nonhuman chatbots. 相似文献

Empirical studies have revealed that teachers face problems when assessing task difficulty for their students. By drawing on research that focuses on how individuals assess what others know, we argue that these difficulties are a consequence of the imputation of one’s own knowledge to others (i.e., social projection). In particular, we tested the assumption that individuals impute more of their own knowledge to others, the more they elaborate what these others might know. In a first experiment, students were asked to judge task difficulty for their best friend. In the second experiment, teacher trainees were asked to assess task difficulty for 9th graders. Results revealed that individuals, who deeply elaborated when assessing task difficulty for another person, more closely relied on their own rating of task difficulty than individuals with a lower elaboration depth. These findings support the notion that social projection becomes stronger, the deeper individuals elaborate. 相似文献

This article presents a new database of 2,654 German nouns rated by a sample of 3,907 subjects on three psycholinguistic attributes:
concreteness, valence, and arousal. As a new means of data collection in the field of psycholinguistic research, all ratings
were obtained via the Internet, using a tailored Web application. Analysis of the obtained word norms showed good agreement
with two existing norm sets. A cluster analysis revealed a plausible set of four classes of nouns: abstract concepts, aversive
events, pleasant activities, and physical objects. In an additional application example, we demonstrate the usefulness of
the database for creating parallel word lists whose elements match as closely as possible. The complete database is available
for free from ftp://ftp.uni-duesseldorf.de/ pub/psycho/lahl/WWN. Moreover, the Web application used for data collection is
inherently capable of collecting word norms in any language and is going to be released for public use as well. 相似文献

A longitudinal study was conducted to investigate the influence of practice on the long-term development of expert pianists' motor skills in a relevant musical context. Temporal evenness in standardized scale playing was assessed twice in 19 pianists within an average time interval of 27 months. Questionnaires were used for retrospective assessment of practice quantity and several qualitative parameters related to practicing of scales. The development of temporal evenness in scale playing over the follow-up period correlated with the practice time accumulated during that period and with the average daily practice time. Expert pianists with an average daily practice time of 3.75h or more showed an improvement of performance in this selected motor skill. No significant association was observed between motor skill development during the follow-up period and the content of practice. Stepwise linear regression revealed a model predicting 43% of the variance of motor skill development, with practice time accumulated during the follow-up period as the only predictor. It was concluded that, in expert pianists, maintenance of motor skills in the selected motor task was strongly influenced by practice quantity. 相似文献
