Work conditions, social status and sex differences in primary and secondary enuresis

From previous investigations on the enuresis problem a distinction between primary and secondary enuresis is established. The first type concerns children who have never been dry and the second those with acquired enuresis. The theory is advanced that primary enuresis is a development problem mainly due to delayed cortical development or insufficient bladder capacity, whereas secondary enuresis is regarded as caused by an increased anxiety level. Some social and psychological factors in this theory, i.e., the mother's working conditions, the social status of the family, and the sex of the child, are empirically examined in an investigation of 82 children 7–15 years old. The results support the view that the main factors in the enuresis problem are related to the child's daily practice and in the socialization form of the family.     

Giving dyadic data analysis away: A user‐friendly app for actor–partner interdependence models

The actor–partner interdependence model (APIM) is widely used for analyzing dyadic data. Although dyadic research has become immensely popular, its statistical complexity can be a barrier. To remedy this, a free user‐friendly web application, called APIM_SEM, has been developed. This app automatically performs the statistical analyses (i.e., structural equation modeling) of both simple and complex APIMs. It allows the researcher to analyze distinguishable or indistinguishable dyads, to examine dyadic patterns, to estimate actor and partner effects of one or two predictors, and to control for covariates. Results are provided in software and text format, complemented by summary tables and figures. As an illustration, the effect of perception of the partner on satisfaction is assessed by fitting APIMs with varying complexity.     

Social status and language comprehension

Abstract.— Previous research on differences in language use in relation to social status have dealt almost exclusively with language production. The present study investigated the comprehension of connected discourse by 116 adult Danes from two different socio-economic status groups, high status (HSES) and low status (LSES). On a task at the lexical level of comprehension (choosing between alternatives to two words in each of four texts) there appeared no differences between HSES and LSES subjects. At the structural level a difference ( p <0.05) was found in drawing conclusions from the texts, but the groups nevertheless agreed completely ( p <0.05) in underlining important segments of the texts. Thus the symmetry between production and comprehension hypothesized by Bernstein did not appear. The results are interpreted in accordance with a general model of language processing. It is suggested that in the future more attention should be paid to variables other than the purely sociological variable of social status or social class.     

Is there an optimal factor structure of the Positive and Negative Syndrome Scale in patients with first‐episode psychosis?

The Positive and Negative Syndrome Scale (PANSS) is the most widely used scale to assess a variety of symptoms in patients with schizophrenia and other psychoses. The factor structure of the PANSS has been examined with confirmatory factor analyses in several studies, but not in a well‐defined first‐episode psychosis sample. The aim of this paper is to examine the statistical fit of five different PANSS models in a first‐episode, non‐affective psychosis sample. Confirmatory factor analyses were performed on PANSS data (n = 588). A main criterion for best fit was defined as the Expected Cross Validation Index (ECVI). No tested model revealed an optimally satisfactory model fit index. The Wallwork/Fortgang five‐factor model demonstrated the most optimal psychometric properties. The corresponding subscales of all evaluated five‐factor models were strongly intercorrelated. The Wallwork/Fortgang five‐factor model was found to be statistically and clinically ideal among patients with first‐episode psychosis. Therefore, we recommend this model in forthcoming studies among patients with first‐episode psychosis. However, to prevent the loss of clinically valuable information on an item level, we do not recommend removing any items from the original form. Our study also implies that the specific choice of model will not have a substantial effect on outcome results in studies on the course and outcome in first‐episode psychosis.     

Psychometric properties of a Danish translation of the Rutter Scale B in a community sample of seven-year-old children

The psychometric properties of a Danish translation of the Rutter Scale B for completion by teachers were examined in a nonreferred sample of 686 7-year-old children. The Danish translation of the Rutter scale had a similar factor structure to the original, producing a three-factor structure corresponding to the subscales. The agreement between the questionnaire and direct observations of the children ten months earlier was fair ( K =0.42). The findings suggest that the translated scale could serve as a rapid and useful screening instrument in clinical and in research settings.     

Common mechanisms in apparent motion perception and visual pattern matching

There are close functional similarities between apparent motion perception and visual pattern matching. In particular, striking functional similarities have been demonstrated between perception of rigid objects in apparent motion and purely mental transformations of visual size and orientation used in comparisons of objects with respect to shape but regardless of size and orientation. In both cases, psychophysical data suggest that differences in visual size are resolved as differences in depth, such that transformation of size is done by translation in depth. Furthermore, the process of perceived or imagined translation appears to be stepwise additive such that a translation over a long distance consists of a sequence of smaller translations, the durations of these steps being additive. Both perceived and imagined rotation also appear to be stepwise additive, and combined transformations of size and orientation appear to be done by alternation of small steps of pure translation and small steps of pure rotation. The functional similarities suggest that common mechanisms underlie perception of apparent motion and purely mental transformations. In line with this suggestion, functional brain imaging has isolated neural structures in motion area MT used in mental transformation of size.     

Processing differences in the right and left visual half-field

Strings each containing 3 single digits were displayed tachistoscopically in the right and left visual half-field to 59 normal children, 8 to 14 years old. A distinction between 4 types of responses was made. Correct responses most frequently occurred to items in the left half-field, no half-field advantages was found for reversed responses, and wrong-order responses most frequently occurred to items in the right half-field. These results are explained by suggesting a more analog mode of processing in the left visual half-field and a more conceptual mode of processing in the right half-field. The degree of asymmetry was found to be age-related.     

On sensation, perception and thought: A reply to Rönnberg

A traditional partition of cognitive phenomena into sensation, perception and thought is reintroduced in response to recent arguments (Rönnberg, 1990) for conditions that must be met in order to distinguish between perception and cognition. The suggested division seems grossly compatible with Ronnberg's basic aim and receives support from several different lines of inquiry, including single cell recordings in the brain, neurospsychology, computational studies of vision and experimental psychology.     

ANTICIPATED SOCIAL COST AND INTERPERSONAL ACCOMODATION

The paper is concerned with demonstrating the value of social cost—a concept derived from a social psychological theory of prejudice—in analyzing the cognitive processes underlying the encoding of convergent speech acts. A study showed that when speakers anticipate meeting socially significant others immediately, the effect on their perceptual processes is to perceive greater similarity to, and less undesirable traits in, such others. It was argued that this reduction of a perceived linguistic distance between a speaker and the interlocutor, termed perceptual convergence, should facilitate the adoption of convergent speech in the former. Areas for further research were discussed.
