Medical Psychology Services in Dutch General Hospitals: State of the Art Developments and Recommendations for the Future

In this article an overview is presented of the emergence of medical psychology in the care of somatically ill patients. The situation in the Netherlands can be considered as prototypical. For 60 years, clinical psychologists have been working in general, teaching and academic hospitals. Nowadays, they are an integrated non-medical specialism working in the medical setting of hospitals in the Netherlands, and are a full-member of the medical board. This paper discusses several topics: the position of the general hospital in the health care system in the Netherlands, the emergence of medical psychology in Dutch hospitals, the role of the professional association of medical psychologists, and the characteristics of patients seen by clinical psychologists. Following the discussion about the situation of medical psychology in other countries, recommendations are formulated for the further development of medical psychology in the Netherlands as well as in other countries.     

Erratic Appliances and Energy Awareness

We are exploring how to increase energy awareness through critical interaction design, creating objects that expose issues related to energy consumption in various ways. To draw attention to energy beyond ordinary conceptions as a technical solution in everyday life, we inquire into other ways of relating to energy in design and to uncover the properties of energy as a design material. To learn more about how energy can be made more present in product design, we have been redesigning a series of everyday objects around the theme of ‘erratic appliances’. As household energy consumption increases, these appliances start to behave strangely. The aim was to use designerly and experience-based means to make people aware of their energy consumption instead of measuring energy consumption solely with meters and numeric displays.     

The effect of category learning on the representation of shape: dimensions can be biased but not differentiated

Recent studies have suggested a profound influence of category learning on visual perception, resulting in independent processing of previously integral dimensions. The authors reinvestigate this issue for shape dimensions. They first extend previous findings that some shape dimensions (aspect ratio and curvature) are processed in a separable way, whereas others (radial frequency components) are not. They then show that a category-learning phase improved the discrimination of a relevant with respect to an irrelevant dimension, but only for separable dimensions. No similar effect was found on the relative sensitivity for integral shape dimensions. Thus, category learning is capable of biasing separable shape dimensions but does not alter the status of dimensions in the visual system as either separable or integral.     

The memorability of names and the divergent effects of prior experience

Pre-experimental familiarity can have paradoxical effects on episodic memory. Knowledge of the stimulus domain usually enhances memory, but word frequency—a presumed correlate of prior experience—is negatively related to recognition accuracy. The present study examined episodic recognition of names and its relation to two measures of pre-experimental knowledge, name frequency, and fame. Frequency was operationalised as the number of hits in a national telephone directory, and fame as hits on national mass media websites. Recognition accuracy was increased by fame, but diminished by frequency. Four experiments confirmed the findings, using yes/no recognition, ROC curves, and remember-know paradigms. Hit rates were consistently more strongly influenced by fame than by frequency, whereas the reverse was true for false alarm rates. These dissociations suggest that two different forms of semantic memory, specific and nonspecific knowledge, interact with episodic memory in separate ways.     

Possible worlds semantics: A research program that cannot fail?

Providing a possible worlds semantics for a logic involves choosing a class of possible worlds models, and setting up a truth definition connecting formulas of the logic with statements about these models. This scheme is so flexible that a danger arises: perhaps, any (reasonable) logic whatsoever can be modelled in this way. Thus, the enterprise would lose its essential tension. Fortunately, it may be shown that the so-called incompleteness-examples from modal logic resist possible worlds modelling, even in the above wider sense. More systematically, we investigate the interplay of truth definitions and model conditions, proving a preservation theorem characterizing those types of truth definition which generate the minimal modal logic.     

Beauty in the blink of an eye: The time course of aesthetic experiences

Under normal circumstances, perception runs very fast and seemingly automatic. In just a few ms, we go from sensory features to perceiving objects. This fast time course does not only apply to general perceptual aspects but also to what we call higher-level judgements. Inspired by the study on ‘very first impressions’ by Bar, Neta, and Linz (2006, Emotion, 6 , 269) the current research examined the speed and time course of three aspects of the aesthetic experience, namely beauty, specialness, and impressiveness. Participants were presented with 54 reproductions of paintings that covered a wide variety of artistic styles and contents. Presentation times were 10, 50, 100 and 500 ms in Experiment 1 and 20, 30 and 40 ms in Experiment 2. Our results not only show that consistent aesthetic judgements can be formed based on very brief glances of information, but that this speed of aesthetic impression formation also differs between different aesthetic judgements. Apparently, impressiveness judgements require longer exposure times than impressions of beauty or specialness. The results provide important evidence for our understanding of the time course of aesthetic experiences.     

Procedural justice and the hedonic principle: how approach versus avoidance motivation influences the psychology of voice

The authors investigate the relation between the hedonic principle (people's motivations to approach pleasure and to avoid pain) and procedural justice. They explore whether approach or avoidance motivation increases the effect that people feel they were treated more fairly following procedures that do versus do not allow them an opportunity to voice their opinion. Experiments 1 and 2 reveal that these procedures influence procedural justice judgments more strongly when people conduct approach motor action (arm flexion) than when they conduct avoidance motor action (arm extension). Experiment 3 indicates that individual-difference measures of participants' approach motivations predicted procedural justice judgments following voice versus no-voice procedures. The authors conclude that people's motivational orientations stimulate their fairness-based reactions to voice procedures.     

When forgiving enhances psychological well-being: the role of interpersonal commitment

The present research addresses the question of when and why forgiving might enhance psychological well-being. The authors predict that forgiving is associated with enhanced well-being but that this association should be more pronounced in relationships of strong rather than weak commitment. This hypothesis received good support in Studies 1-3. Studies 2 and 3 addressed the issue of why forgiving might be associated with psychological well-being, revealing that this association was reduced after controlling for psychological tension (i.e., a psychological state of discomfort due to conflicting cognitions and feelings). Study 4 revealed that in the context of marital relationships, tendencies toward forgiving one's spouse exhibited a more pronounced association with psychological well-being than did tendencies to forgive others in general.     

The phenotypic and genotypic relation between working memory speed and capacity

This study examined the phenotypic and genotypic relationship between working memory speed (WMS) and working memory capacity (WMC) in 12-year-old twins and their siblings (N = 409). To asses WMS all children performed a reaction time task with three memory loads from which a basic mental speed measure and the derived slope were used. WMC was measured with two subtests of the WISC-R, namely Arithmetic and Digit Span. The phenotypic correlations among the WMS and WMC indices were around − 0.30. Heritabilities for all variables ranged from 43% to 56%. Structural equating modelling revealed that a model with two genetic factors, representing WMS and WMC, which were correlated (− 0.54) fitted the data best, indicating that WMS and WMC are partly mediated by the same set of genes and partly by separate sets of genes. When general IQ was simultaneously analysed with the data the correlation between the genetic factors for WMS and WMC decreased (− 0.25), but was still significant. This means that  50% of the genetic correlation between WMS and WMC is explained by IQ.     

Crosstalk between on-line and off-line processing of visual features

Three dual-task experiments were conducted to investigate the relation between immediate, on-line judgments about visual features and delayed, off-line judgments. One hypothesis (selective interference) predicted that dual-task performance would be challenged specifically within a visual dimension, as both tasks compete for the same resources. Another hypothesis (cost of switching) made the opposite prediction. In Experiment 1, participants performed either color or shape discriminations in the on-line and off-line visual tasks, with systematic variation of feature similarity between the on-line and off-line features. In Experiment 2, participants performed either color or shape discriminations in the off-line task and color discriminations in the on-line task, with no overlap between the on-line and off-line features. In Experiment 3, participants performed color discriminations in both the on-line and off-line tasks, with partially overlapping stimulus sets. Altogether, the data from the three experiments provided evidence in favor of the hypothesis of cost of switching. Stimulus–stimulus compatibility effects between features in the off-line task and those in the on-line task further underscored the perceptual nature of the crosstalk.
