Interactive insight problem solving

Insight problem solving was investigated with the matchstick algebra problems developed by Knoblich, Ohlsson, Haider, and Rhenius (1999 Knoblich, G., Ohlsson, S., Haider, H. and Rhenius, D. 1999. Constraint relaxation and chunk decomposition in insight problem solving. Journal of Experimental Psychology: Learning, Memory and Cognition, 25: 1534–1555. [Crossref], [Web of Science ®] , [Google Scholar]). These problems are false equations expressed with Roman numerals that can be made true bymoving one matchstick. In a first group participants examined a static two-dimensional representation of the false algebraic expression and told the experimenter which matchstick should be moved. In a second group, participants interacted with a three-dimensional representation of the false equation. Success rates in the static group for different problem types replicated the pattern of data reported in Knoblich et al. (1999 Knoblich, G., Ohlsson, S., Haider, H. and Rhenius, D. 1999. Constraint relaxation and chunk decomposition in insight problem solving. Journal of Experimental Psychology: Learning, Memory and Cognition, 25: 1534–1555. [Crossref], [Web of Science ®] , [Google Scholar]). However, participants in the interactive group were significantly more likely to achieve insight. Problem-solving success in the static group was best predicted by performance on a test of numeracy, whereas in the interactive group it was best predicted by performance on a test of visuo-spatial reasoning. Implications for process models of problem solving are discussed.     

Two facets of cognitive control in analogical mapping: The role of semantic interference resolution andgoal-driven structure selection

The study used scene analogies to investigate two component processes of analogical thinking: resolution of semantic interference, which emerges when the proper mapping between analogically matching objects is incoherent with their categorical features (e.g., stereotypical functions), and goal-driven selection of the key relational structure, by directing attention to the most promising objects which constitute that structure among many other candidate objects. We manipulated interference by placing in corresponding scenes the objects from one category in different relational roles. Selection was loaded by including additional, relationally irrelevant objects in a scene. We also manipulated relational complexity and the presence of salient objects (people) in relations. Increased load on both interference resolution and selection decreased the accuracy of analogical mapping, but these factors did not interact. Moreover, the factors yielded opposite patterns of interaction with relational complexity. Finally, salience eased selection, but tended to negatively influence interference resolution. In summary, inference resolution and selection seem to constitute two relatively independent facets of cognitive control involved in analogical thinking. Selection may act before mapping occurs, while interference influences analogy making only if an interfering object takes part in mapping.     

No time for compromises: Age as a moderator of the relation between needs–supply fit and job satisfaction

In the light of the current demographic change, organizations need to be aware of factors influencing job satisfaction of older workers in order to maintain high motivation and commitment. The present study addresses this issue by examining the moderating effect of age on the relationship between needs–supply fit and job satisfaction. Based on the general assumption that older workers are more sensitive to circumstances that threaten their well-being (Carstensen, 2006 Carstensen, L. L. 2006. The influence of a sense of time on human development. Science, 312: 1913–1915. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), we hypothesize that older as compared to younger workers should react more negatively to a misfit between their needs and available job supplies. Hence, older as compared to younger workers should report lower levels of job satisfaction when experiencing a misfit between needs and supplies. This hypothesis was tested in a sample of 471 employed workers from different occupational areas. Results confirmed our hypothesis for four out of five domains of needs–supply fit: Significant three-way interactions between needs, supply, and age were observed. The present result that older as compared to younger workers react more strongly to needs–supply misfits additionally underlines the benefits of considering age-related changes in work values and needs in age-sensitive human resource practices.     

A Psychological Means for the Control and Prevention of Industrial Stress in Computerized Working Places

Abstract

There are common traditions in investigations into industrial stress and other kinds of poor workers' states in Western and Russian/Soviet applied psychology. Based upon these traditions we attempt to overview the main domains of research and possibilities for their application in a practical sense. Proposed psychodiagnostic and psychoprophylactic approaches have to be developed according to different kinds of work situations and technological progress. But the intention of basing research on the analysis of structural mechanisms of activity regulation seems to us the most productive in all of these cases. It corresponds to the increasing demands on human internal resources and mental activities in modern technological systems.     

Remembering Numbers in Old Age: Mnemonic Training Versus Self-Generated Strategy Training

The effectiveness of two memory training programs designed to enhance four-digit number recall was examined in 90 healthy older adults. One group received instruction and training in the number-consonant mnemonic, whereas another group was instructed to adopt their own encoding and retrieval strategies to enhance number recall. Also, a control group receiving no training between testing occasions was included. The criterion task was administered according to the Buschke selective reminding procedure. Posttest performance was evaluated with and without cognitive support for remembering (i.e., verbal cues). Under unsupported conditions, the mnemonic group improved number recall following training and the self-generated strategy group showed a tendency in the same direction. When support was provided, group differences in favor of the two training groups increased. In addition, no training-related gains were observed in two verbal transfer tasks. The relatively similar patterns of gains in the two intervention groups were discussed in terms of advantages and disadvantages in the two training regimens balancing each other.     

Task dependent modulation of exogenous attention: Effects of target duration and intervening events

Inhibition of return (IOR) consists of slower reaction times in response to stimuli appearing at previously attended or inspected locations. The exact mechanisms underlying the effect have not yet been determined. In the present work, we manipulated two variables, target duration and intervening event (fixation cue between cue and target), through which we modulated the IOR effect as a function of task. When the target was presented until response, the presence of an intervening event made the cueing effect more negative in all tasks, although facilitation in the absence of an intervening event was only observed in discrimination and go–no-go tasks. When the target duration was 50 ms, the effect of the intervening event on cueing was also only observed for the discrimination and go–no-go tasks. Target duration had no effect at all in the discrimination task. Possible mechanisms for these modulations (detection cost and spatial selection benefit, both of which are based on cue–target integration processes) are discussed.     

Textures shape the attentional focus: Evidence from exogenous and endogenous cueing

The spatial cueing paradigm (Posner Quarterly Journal of Experimental Psychology 32:3–25, 1980) has often been used to investigate the time course of the deployment of visual attention in space. In a series of eight experiments we investigated whether spatial cues would not only enhance processing of stimuli presented at cued locations, but also enhance processing of the entire texture in which the stimuli were presented. Results showed highest accuracy for responses to stimuli presented at cued locations, a replication of the traditional cueing effect (Posner 1980). Additionally, stimuli presented at uncued locations were responded to with higher accuracy when they were presented inside the same texture as the cued location, as compared with stimuli presented outside the texture with the cued location. To investigate this texture advantage for both automatic and voluntary attention deployment, exogenous and endogenous cues were used. The texture advantage was observed for short interstimulus intervals (ISIs) of 50 and 100 ms for exogenous cues and for a longer ISI of 200 ms for endogenous cues. These findings indicate that the arrangement of task-irrelevant visual stimuli also can have a large impact on the cueing effect. This suggests that visual spatial attention spreads texture-wise across the visual field. Control experiments revealed that the homogeneity within texture elements contributes most to the effect but that the texture advantage is a function of both orientation contrast at the texture border and homogeneity within texture elements.

The European Early Promotion Project: A new primary health care service to promote children's mental health

The number of children in Europe with significant psychologic and social problems is large and increasing. This article describes an innovative crosscultural method of working with families to promote the psychosocial well being of children and prevent the development of psychologic and social problems. A study designed to evaluate the effects of the service is also presented. Primary health care workers in five European countries have been trained to conduct promotional interviews with all prospective mothers in their area one month before and one month after birth. They have also been taught to work with mothers identified as in need of support as a parent by using a specific counselling model to try to prevent the onset of child mental health difficulties. Effects of the intervention on children's psychologic development and family adaptation are being evaluated at two years in comparison with matched groups not receiving the intervention. ©2002 Michigan Association for Infant Mental Health.     

Do Middle-Class Students Perceive Poor Women and Poor Men Differently?

In this study, we examined attitudes toward poor women, stereotypes about them, attributions for their poverty, and whether these thoughts and feelings differ from those about poor men. In our Midwestern college students sample (n = 206), attitudes toward poor women were significantly more positive than attitudes toward poor men. In addition, stereotypes of poor women were both more positive and more consistent with gender stereotypes than were those of poor men. Participants endorsed internal attributions for the poverty of both women and men more strongly than external or cultural attributions. However, the content of these attributions was different for the two target groups. Poor women were held responsible for nontraditional familial and reproductive patterns, whereas poor men were held responsible for lack of initiative and self-improvement. For poor men, all types of attributions included references to ability or willingness to work. The three types of attributions were more conceptually distinct for poor women.
