Effect of time and space uncertainty on a vigilance task

Two groups, each of 12 Ss, were instructed to detect increments in light level from displays of one or five lights. Signals appeared in regular and in irregular intervals. The display was flashed on simultaneously for 0.8 sec every 3.2 sec. Signal detection was superior with a display of one light than with a display of five lights. For two extreme response criteria, there was a decrement of false alarms and an increment of beta during a run. These changes were not dependent upon time and spatial uncertainty. There were no systematic changes in correct detections and d’ during a run. No difference was found between central and peripheral light positions. Correlation of measures was also examined.     

Mathematical structures and psychological measurements

The nature of psychological measurements in relation to mathematical structures and representations is examined. Some very general notions concerning algebras and systems are introduced and applied to physical and number systems, and to measurement theory. It is shown that the classical intensive and extensive dimensions of measurements with their respective ordinal and additive scales are not adequate to describe physical events without the introduction of the notions of dimensional units and of dimensional homogeneity. It is also shown that in the absence of these notions, the resulting systems of magnitudes have only a very restricted kind of isomorphism with the real number system, and hence have little or no mathematical representations. An alternative in the form of an extended theory of measurements is developed. A third dimension of measurement, the supra-extensive dimension, is introduced; and a new scale, the multiplicative scale, is associated with it. It is shown that supra-extensive magnitudes do constitute systems isomorphic with the system of real numbers and that they alone can be given mathematical representations. Physical quantities are supra-extensive magnitudes. In contrast, to date, psychological quantities are either intensive or extensive, but never of the third kind. This, it is felt, is the reason why mathematical representations have been few and without success in psychology as contrasted to the physical sciences. In particular, the Weber-Fechner relation is examined and shown to be invalid in two respects. It is concluded that the construction of multiplicative scales in psychology, or the equivalent use of dimensional analysis, alone will enable the development of fruitful mathematical theories in this area of investigation.The editors of this journal should perhaps point out that unanimous agreement with the arguments and points of view expressed in this article is not anticipated. They believe, however, that its publication may stimulate needed thinking and clarification of problems basic to psychological measurement and thus serve the purpose for which the journal was founded.

Mothers', fathers' and children's perceptions of parents' expectations about children's family obligations in nine countries

Children's family obligations involve assistance and respect that children are expected to provide to immediate and extended family members and reflect beliefs related to family life that may differ across cultural groups. Mothers, fathers and children (N = 1432 families) in 13 cultural groups in 9 countries (China, Colombia, Italy, Jordan, Kenya, Philippines, Sweden, Thailand and United States) reported on their expectations regarding children's family obligations and parenting attitudes and behaviours. Within families, mothers and fathers had more concordant expectations regarding children's family obligations than did parents and children. Parenting behaviours that were warmer, less neglectful and more controlling as well as parenting attitudes that were more authoritarian were related to higher expectations regarding children's family obligations between families within cultures as well as between cultures. These international findings advance understanding of children's family obligations by contextualising them both within families and across a number of diverse cultural groups in 9 countries.     

Links Among Cognitive Empathy,Theory of Mind,and Affective Perspective Taking by Young Children

The authors investigated the development of the affective, cognitive, and behavioral components of empathy in preschoolers, specifically examining how cognitive empathy is linked to theory of mind and affective perspective taking. Participants were 158 children aged 4–6 years. They listened to narratives and then answered questions about the protagonists' emotions. The affective component was probed with the question, “How do you feel seeing the little girl/boy?”; the cognitive component with the question, “Why do you feel [emotion shared with the character]?”; and the behavioral one with the question, “What would you do if you were next to the little boy/girl [experiencing an emotional scenario]?” Results revealed a developmental sequence in the self-focused attribution of cognitive empathy, and a trend toward a developmental sequence for behavioral empathy, which underwent a slight linear increase between 4 and 6 years old. Affective empathy remained stable. More interestingly, they showed that cognitive empathy is linked to both theory of mind and affective perspective taking.     

Neuroticism and Depression in Children: The Role of Cognitive Emotion Regulation Strategies

This study's general objective was to analyze whether different types of cognitive emotion regulation strategies (CERS), namely adaptive strategies—specifically positive refocusing and positive reappraisal—and maladaptive strategies—self-blame, catastrophizing, and rumination—mediated the neuroticism-depression relationship in children 9–12 years old, and whether gender and school transition moderated the relationships proposed. A self-reporting measure was administered to 315 children to evaluate said variables. The resulting data were analyzed using structural equations. The study verified that maladaptive CERS partially mediated neuroticism's relationship with depression, while adaptive CERS, though negatively associated with depression, did not show a mediating effect on this relationship. The results provide evidence of the mediating function of maladaptive CERS on the neuroticism-depression relationship. Gender and school transition did not moderate the relationships proposed. Because, by their very nature, these strategies are modifiable, these results constitute an important finding that can be transferred to the design and content of child mental health prevention and promotion programs.     

Factor Structure of the Torrance Tests of Creative Thinking Verbal Form B in a Spanish‐speaking Population

The objective of this study was to compare, through a Confirmatory Factor Analysis, two different theoretical models that explain the operationalized creativity construct with the Verbal Torrance Tests of Creative Thinking (TTCT), Form B. Model 1 is represented by six factors which correspond to each activity and its respective indicators while Model 2 is integrated by three factors which correspond to each TTCT ability (i.e., Fluency, Originality, and Flexibility) and the corresponding indicators for each variable. The study was carried out with a sample consisting of 432 Spanish‐speaking youngsters of both sexes aged 15–26. According to the research findings, the model which showed the most satisfactory fit identifies six correlated factors that correspond to each of the activities proposed (χ² = 414.48; df = 116; χ²/df = 3.57; GFI = .90; NFI = .95; CFI = .96 and RMSEA = .077). These results are discussed according to its psychometric implications for the construct assessment in different fields.     

Disorganization and Individual Psychotherapy for Schizophrenia: A Case Report of Metacognitive Reflection and Insight Therapy

Despite being a characteristic symptom of schizophrenia, implications for therapy with persons experiencing prominent disorganization have received less attention in the psychotherapy literature than have other aspects of the disorder. As such, formal thought disorder may be viewed largely as a barrier to effective participation in therapy. In contrast, though, a range of writers from varied traditions have stressed that this feature of schizophrenia is meaningful and improved coherence of speech is an important and viable component of treatment and recovery. This paper suggests that an emergent integrative psychotherapy, metacognitive reflection and insight therapy (MERIT), may be well-suited for work with persons experiencing disorganization symptoms. A brief overview of MERIT is provided, followed by a case report of an 18-month course of therapy with a man with severely disorganized speech.
