TOPOLOGICAL AND EUCLIDEAN SPATIAL FEATURES NOTED BY CHILDREN

The question explored in this study is whether the spatial-perceptual difficulties experienced in some cultures could be partly accounted for in terms of a persistence of predominantly topological functioning. An oddity-choice task was devised consisting of one set of regular and another of irregular figures such that responses could be classified as topological (T), Euclidean (E) or “unrelated” (U), the last indicating failure to categorize figures consistently. A total of 415 children aged 4–12 were tested in Hong Kong, India, Scotland and Zambia. Few significant age trends but highly significant cultural and sub-cultural differences were found. Contrary to expectation, T responses were roughly constant while the proportion of both E and U responses showed systematic cross-cultural variations. There was evidence that it is U responses rather than the proportion of E responses which directly reflect spatial ability. The factors producing cultural and sub-cultural differences are discussed.     

Syntactic structure and acoustic pattern in speech perception Arthur Wingfield

The interaction of syntactic structure and acoustic pattern in perceptual segmentation of heard speech was investigated using sentences recorded with intonation patterns appropriate to their underlying structure and sentences where intonation was placed in direct conflict with the underlying structure. Speech samples were monitored through dichotic earphones with messages switched from one ear to the other either between or within major linguistic constituents. Analysis of errors in source localization and in sentence reproduction suggested a primary role of acoustic pattern in segmentation is to cue underlying syntactic structure. Two subsidiary experiments provided evidence that observed effects were related to active perceptual processing of the speech signal.     

ORIENTATION AND PERCEPTION OF PICTORIAL DEPTH

Des échantillons d'écoliers zambiens et écossais sont soumis à une épreuve d'interprétation de dessin géométrique simple, présenté selon deux orientations: la figure est symétrique soit par rapport à L'axe vertical, soit par rapport à un axe incliné. Les résultats montrent que L'orientation affecte les réponses de L'échantillon écossais: les réponses bi-dimensionnelles sont plus fréquentes avec L'axe de symétrie vertical; mais ce n'est pas le cas pour les enfants zambiens. On ne constate aucun progrès dans la discrimination des deux orientations avec L'âge ou la scolarité dans L'échantillon zambien. L'auteur discute des implications de ces résultats.     

GENERATION OF WORDS FROM STEREOSCOPICALLY PRESENTED NON-WORD STRINGS OF LETTERS

R ommetveit , R., B erkley , M. & B røgger , J. Generation of words from stereoscopically presented non-word strings of letters. Scand. J. Psychol. , 1968, 9, 150–156.—Subjects were exposed to stereoscopically presented pairs of non-word strings of letters (e.g. shar/shap). Instead of responding with either left- or right-eye image, they frequently reported seeing a word generated by combining the two images (e.g., 'sharp'). The way a particular pair of superimposed letters (such as r and p) will be processed, seemed to depend upon semantic and morphological aspects. As rivals for the same serial position in two different words, only one of them will be 'seen'. When appropriate as neighbors in the same word, both tend to be seen, and in the appropriate spatial arrangement.     

A note on direct products and ultraproducts of logical matrices

In this contribution we shall characterize matrix consequence operation determined by a direct product and an ultraproduct of a family of logical matrices. As an application we shall describe finite consequence operations with the help of ultrapowers.     

Behavioral objectives in training for competence in the administration of individual intelligence tests

Competency standards are important to school psychology training, and this study demonstrates, in the area of individual intelligence test administration, how competency standards can be implemented. The study sets up behavioral objectives, determines what training is required for specified levels of mastery, and shows what specific training procedures contribute to the achievement of competency.     

Sola Scriptura—A Hermeneutical Impossibility and a Doctrinal Necessity: Twenty‐One Theses

The following theses represent an attempt to delineate some of the contemporary basic conditions for maintaining the use of the sola Scriptura in the Lutheran churches. This must, I argue, be done without using it as a means for ignoring other types of information and experience than that which is contained in the Scriptures. I argue that sola Scriptura formulates what is necessary for salvation, but cannot be used to delineate or present all information that is necessary to live in the contemporary world and interpret all contemporary experience.     

Riding the waves: A functional‐cognitive perspective on the relations among behaviour therapy,cognitive behaviour therapy and acceptance and commitment therapy

Different types of therapy explain psychopathology and the effects of psychotherapy differently. Different explanations are, however, not necessarily mutually exclusive. Based on the idea that functional and cognitive explanations are situated at different levels, we argue that functional therapies such as traditional Behaviour Therapy (BT) and Acceptance and Commitment Therapy (ACT) are not necessarily incompatible with Cognitive Behaviour Therapy (CBT). Whether a functional and a cognitive therapy actually align depends on whether they highlight the same type of environmental causes. This functional‐cognitive perspective reveals various differences and communalities among BT, CBT and ACT.     

Time-Varying Treatments in Observational Studies: Marginal Structural Models of the Effects of Early Grade Retention on Math Achievement

One of the main objectives of many empirical studies in the social and behavioral sciences is to assess the causal effect of a treatment or intervention on the occurrence of a certain event. The randomized controlled trial is generally considered the gold standard to evaluate such causal effects. However, for ethical or practical reasons, social scientists are often bound to the use of nonexperimental, observational designs. When the treatment and control group are different with regard to variables that are related to the outcome, this may induce the problem of confounding. A variety of statistical techniques, such as regression, matching, and subclassification, is now available and routinely used to adjust for confounding due to measured variables. However, these techniques are not appropriate for dealing with time-varying confounding, which arises in situations where the treatment or intervention can be received at multiple timepoints. In this article, we explain the use of marginal structural models and inverse probability weighting to control for time-varying confounding in observational studies. We illustrate the approach with an empirical example of grade retention effects on mathematics development throughout primary school.
