The role of age on reactivity and memory for emotional pictures

The purpose of this study was to investigate subjects' reactivity to emotional pictures and their recollection of these pictures, and to examine these two factors as they relate to age. Adolescents and young adults were shown emotionally arousing scenic pictures for long (4-s) and very brief (50-ms) durations. Recognition of the pictures and recall and recognition of words presented along with the pictures were assessed both immediately after the presentation and six weeks later. The results showed that very negative pictures are retained better than neutral or even positive pictures, and that very negative pictures reduce memory for associated information. It was also found that adolescents show a somewhat lower reactivity to very negative pictures and a higher degree of retention of these pictures than adults. The results are discussed in relation to (a) habituation effects, (b) strategies that subjects might develop to block emotional involvement, and (c) the notion that watching violence might serve as a powerful prime to socially undesirable behaviour.     

Color naming: A mapping in the IMCS of common color terms

This study can be considered a follow-up of the investigations of basic color terms by Berlin & Kay and others following their paradigm. It is complementary to these inasmuch as a different method was used for identifying focal areas and boundaries of common color categories, namely semantic differential scales and isosemantic mapping. Further, colors from the entire color space were studied. No comparisons were made between languages, this study being only concerned with the Swedish language. The purpose of this study was to provide a more thorough mapping of the "spread gradients" in various areas of the NCS color space of color categories as represented by the most common color terms.     

Competence in Children at Risk for Psychopathology Predicted from Confirmatory and Disconfirmatory Family Communication

The relationship between confirmation/ disconfirmation in parental and family communication and offspring social competence was examined in 59 families in which at least one of the parents had been hospitalized for a functional psychiatric disorder. Communication samples were obtained using the Consensus Rorschach procedure both with parental couples and with parent-child family units. The communication was analyzed using the Confirmation-Disconfirmation Coding System (CONDIS). The competence at school of 7-and 10-year-old boys was rated by both peers and teachers. Competence at home was rated by the parents. The results indicated that the more competent the high-risk children were, both at school and at home, the more their family communicated in confirmatory ways and the less they communicated in disconfirmatory ways. Furthermore, although the parental couple CONDIS score and the family CONDIS score were modestly correlated, each contributed separately to the prediction of offspring competence. These communication data were not significantly related to parental psychopathology, neither severity of parental impairment nor the diagnosis of the patient-parent.     

Determinants of word fragment completion

A current debate in the memory literature concerns the validity of word fragment completion (WFC) as a test of implicit memory. It has been claimed that language variables exert a strong influence on the task, and that the task reflects memory only to a small extent (Hintzman & Hartry, 1990). For these reasons, the use of contingency analyses of recognition and WFC performance as a means of studying underlying memory processes has been criticized. The present study addressed this issue by examining the influence of language variables on completion of a set of computer generated single-solution fragments of Swedish words (Olofsson & Nyberg, 1992). It was found that language variables indeed had a large effect on completion performance, and that priming only accounted for a small portion of variance in the task. It is therefore suggested that the method of triangulation should be employed for contingency analyses involving WFC.     

Swedish norms for completion of word stems and unique word fragments

Swedish norms for completion of word stems and single-solution word fragments, with few or many letters specified, were obtained from Swedish students. Comparisons were made for completion rates between stems and fragments that were possible to complete with the same word. As expected, completion rates for fragments were generally superior to those of word stems since the word stems allowed alternative completions. Adding one letter to the word stems and fragments resulted in a significant increase in the probability of completion, for both stems and fragments. A stepwise regression analysis was conducted in order to partial out factors determining the completion probability for fragments. The ratio of specified letters to blank characters, and the familiarity of the solution was found to be the most important factors. Finally, the effect of number of given letters in the word stem on the number of generated words per stem was studied. The mean number of words generated per stem was found to be equal for both two- and three-letter word stems.     

RASP: A system for the analysis of memory tasks

The purpose of this paper is to introduce a system for the analysis of memory tasks. The system involves four basic task dimensions, derived from an ecological analysis of memory functioning: Reproductivity (R), Acquisition (A), Sufficiency (S), and Productivity (P). Three studies are reported in which professional memory psychologists were asked to rate sets of standard laboratory and more ecologically relevant memory tasks in terms of the four RASP dimensions. In general, results implied independence across the two sets of tasks between the four dimensions. Interrater reliabilities were found to be modest to high. However, it was suggested that RASP best be used as a tool for understanding the meaningful relations that exist among dimensions within general sets or pools of tasks, for different classes of tasks, as well as for prototypical tasks. We argue that, especially when the relationship between RASP profiles for two particular tasks is crossvalidated by behavioral data, and conflict with assumptions about what memory systems or processes are involved, then there is a potential for conceptual refinement. This refinement could be attained either through an increased theoretical generalization, or through an increased theoretical precision. Based on obtained RASP information at the level of classes of tasks (e.g., episodic vs. semantic) as well as at a prototypical task level (e.g., word recall vs. prose recall), several intriguing memory phenomena are discussed. Finally, we suggest that RASP may serve as a tool for reducing the number of task-specific assumptions of what systems and processes mediate memory performance.     

Disconfirmatory feedback in families of schizophrenics

A new approach to the study of family communication and psychopathology, in particular schizophrenia, using Saugstad's theory about use of language as its point of departure is presented. Conflicts between family members were observed and measured using a new unrevealed difference technique, the Colour Conflict Method (CCM). Communication was analysed in terms of continuous feedback processes, using the new computerized method, Confirmation-Disconfirmation Coding System (CONDIS). Feedback mechanisms in the internal communication of families of schizophrenics, normals, and non-schizophrenic pathological controls (n = 21) are described. The findings show that families of schizophrenics lack the ability to adapt their communication to changing situational requirements. When conflicts were introduced, families of schizophrenics-in contrast to non-schizophrenics within the extended schizophrenia spectrum and normals-increased their frequency of disconfirmatory feedback reactions instead of expressing disagreements openly. This was due to active disqualifications occurring between the parents and from the parents towards their schizophrenic offspring, who reacted with incomprehensible egocentric communication acts.     

Episodic remembering in young adults, 73-year-olds, and 82-year-olds

Younger adults (mean age = 20.6), 73-year-olds, and 82-year-olds were examined in free and cued recall of words preceded by standard instructions or organizational instructions. The younger adults outperformed the elderly groups in free and cued recall preceded by standard instructions. When organizational instructions were provided, recall differences between the younger adults and the 73-year-olds were eliminated, while both these groups outperformed the 82-year-olds. Within-group comparisons showed that the younger group was relatively independent of contextual support at encoding (organizational instructions) and retrieval (cues) respectively. Furthermore, the group of 73-year-olds was able to utilize support at both stages of remembering, whereas the group of 82-year-olds utilized contextual support only at retrieval. The results were compared with research on memory development in childhood through the application of Ribot's law.
