The computer program Fractional Design Wizard creates fractional factorial designs that are cost-effective and especially useful for discarding irrelevant factors from a large number of possible candidates. The program is intended for researchers who are relativelynew to the field of fractional design and who want to acquaint themselves with the use of fractions for the reduction of large experimental designs. Fractional designs allow estimation of main effects, and sometimes two-way interactions, without one’s having to examine all treatment conditions. The program needs Microsoft Windows 95 or better and 32 MB of memory. In a step-by-step fashion, the user can specify the required properties of the fractional design. When there are more valid designs, the user can generate these successively If necessary the user can go back to diminish the requirements. The output can be copied, printed, and saved. The program generates all the information that is needed for the use and interpretation of fractional designs. A help file explains the use of the program and also the purpose, the analysis, and the interpretation of fractional designs. The program, which is written in Object Pascal, is available as freeware on www.fss.uu.nl/ms/hl/fracdes.htm. 相似文献

Inconsistency in the spelling-to-sound mapping hurts visual word perception and reading aloud (i.e., the traditional consistency effect). In the present experiment, we found a consistency effect in auditory word perception: Words with phonological rimes that could be spelled in multiple ways produced longer auditory lexical decision latencies and more errors than did words with rimes that could be spelled only one way. This finding adds strong support to the claim that orthography affects the perception of spoken words. This effect was predicted by a model that assumes a coupling between orthography and phonology that is functional in both visual and auditory word perception. 相似文献

SSRAT is an MS-DOS computer program for two-dimensional sociometric status determination with rating scales. It classifies members of a population into five sociometric status groups, using 3-, 5-, 7-, or 9-point ratings in matrices of assessors and assessed. The processing of rating scales instead of nominations offers several advantages, including increased variability and reliability of the resulting scores. SSRAT is built on the null hypothesis of conditional random attribution of ratings, according to the particular probability distribution of an assessor. Output is available in the form of an ASCII SPSS data file for further statistical processing. Recent studies show that SSRAT, in comparison with nomination methods, (1) is superior in determining popular persons while it detects rejected persons as well, and (2) probably yields classifications that have a higher temporal stability. 相似文献

The dependency of visually induced self-motion sensation upon the density of moving contrasts as well as upon additional stationary contrasts in the foreground or background was investigated. Using two different optokinetic stimuli, a disk rotating in the frontoparallel plane, and the projection of horizontally moving stripes onto a cylindrical screen, it was found that: (1) visually induced self-motion depends upon the density of moving contrasts randomly distributed within the visual field and, with a single contrast area of 1/4 %, is saturated when about 30% of the visual field is moving; (2) additional stationary contrasts inhibit visually induced serf-motion, proportional to their density; and (3) the location in depth of the stationary contrasts has a significant effect upon this inhibition. Their effect is considerable when located in the background of the moving stimuli but weak when appearing in the foreground. It is concluded that dynamic visual spatial orientation relies mainly on information from the seen periphery, both retinal and depth. 相似文献

The influence of non-verbal information on storage of different versions of negated sentences was investigated in a one-trial learning experiment. The negation governed either the subject, the object, or the predicate of the sentence. One group was presented with the sentences together with pictures. Another group the sentences only. The picture which was shown with a sentence represented the sentence content with an alternative for the negated concept. It was found that pictorial information had an effect on the recall of the sentences and that this effect is different for the different sentence versions. 相似文献

During the last years increasing attention has been paid to young children and adolescents with sexual coercive behaviour. During the year 2007 altogether 232 boys and 30 girls under the age of 14 years were reported to the police because of sexual assaults. In NRW an increasing number of in- and out-patient institutions offers specific and unspecific treatment programs for these children. The major aim of our study, which is supported by the Ministry of Employment, Health and Social Affairs of the state of NRW, is to evaluate the wide range of different treatment programs and to find predictors for successful or difficult treatment outcomes. Furthermore we are interested in differences between children with sexual problem behaviour and children with exclusively aggressive problems. So far 23 institutions take part in our research project and our total sample currently consists of 75 boys between 9 - 15 years. A psychometric test battery is applied at the beginning of individual treatment. Our first results highlight differences in socio-demographic data between children with sexual coercive behaviour and children with exclusively aggressive behaviour problems. Compared to children with exclusively aggressive problem behaviour, children with sexual problem behaviour come more often from incomplete families with no male parent, have experienced more psychological and physical violence and have been more often victims of sexual abuse. Compared to children with exclusively aggressive behaviour problems they score significantly higher on the “Depression / Anxiety” scale of the SPS-J, although average T-scores for both groups are within the normal range. Regarding cognitive functioning there are no significant differences between both groups. 相似文献

Background
The therapeutic relationship is a central factor for psychotherapy, which may be at least partially explained by attachment theory. However, research concerning the conditions under which attachment-related needs are activated in treatment followed by possibly dysfunctional coping strategies is rare.Patients and methods
Semi-structured interviews on attachment-related situations in psychotherapies were conducted with 36 inpatients and then rated with regard to content.Results
Triggers for attachment-related needs in therapies were interpersonal conflict and loss, beginning and end of therapy, symptom burden, specific interventions, addressing the therapeutic relationship and change of setting from outpatient to inpatient treatment. This was related to themes of desire for help and support, experience of rejection, self-disclosure and desire for understanding.Conclusions
The attachment system is activated in therapies similar to other interpersonal situations. The results may help to become more sensitive to attachment-related situations and needs. 相似文献69.

Background. Longitudinal studies allow us to identify, which specific maths skills are weak in young children, and whether there is a continuing weakness in these areas throughout their school years. Aims. This 2‐year study investigated whether certain socio‐demographic variables affect early mathematical competency in children aged 5–7 years. Sample. A randomly selected sample of 127 students (64 female; 63 male) participated. At the start of the study, the students were approximately 5 years old (M= 5.2; SD= 0.28; range = 4.5–5.8). Method . The students were assessed using the Early Numeracy Test and then allocated to a high (n= 26), middle (n= 76), or low (n= 25) achievers group. The same children were assessed again with the Early Numeracy Test at 6 and 7 years old, respectively. Eight socio‐demographic characteristics were also evaluated: family model, education of the parent(s), job of the parent(s), number of family members, birth order, number of computers at home, frequency of teacher visits, and hours watching television. Results . Early Numeracy Test scores were more consistent for the high‐achievers group than for the low‐achievers group. Approximately 5.5% of low achievers obtained low scores throughout the study. A link between specific socio‐demographic characteristics and early achievement in mathematics was only found for number of computers at home. Conclusions . The level of mathematical ability among students aged 5–7 years remains relatively stable regardless of the initial level of achievement. However, early screening for mathematics learning disabilities could be useful in helping low‐achieving students overcome learning obstacles. 相似文献

A key ingredient in the current proposal of the DSM-5 Work Group on Personality and Personality Disorders is the assessment of overall severity of impairment in personality functioning: the Levels of Personality Functioning Scale (LPFS). The aim of this article is to contribute a conceptual and empirical discussion of the LPFS from the perspective of the Operationalized Psychodynamic Diagnosis (OPD) system (OPD Task Force, 2008 ). First, we introduce the OPD Levels of Structural Integration Axis (OPD-LSIA), a measure of individual differences in severity of personality dysfunction that is rooted in psychodynamic theory. We show that the OPD-LSIA is reliable, valid, and highly associated with observer ratings of personality disorders. In the second part, we present results from an OPD expert consensus study exploring potential limitations of the current LPFS item set from the perspective of the OPD-LSIA. We conclude with highlighting implications for future revisions of the DSM-5 proposal. 相似文献
