Time and Money

This article analyzes the simultaneous determination of economic satisfaction and leisure satisfaction, separately for women and for men. Different hypotheses are tested; including the hypothesis that leisure satisfaction depends on both the quantity and quality of leisure—where quality is proxied by good intensiveness and social intensiveness. Evidence suggests that gender matters, such that good intensiveness is more important for men (e.g. housing conditions), whereas social intensiveness is more important for women (e.g. the presence of children and participation in leisure-time activities). Conversely, concerning economic satisfaction men appear more directly affected by income levels than women. In addition, we find that intra-household effects and especially individual characteristics are more pronounced for women than for men for both domain satisfactions.     

Domain generality and domain specificity in aesthetic appreciation

Aesthetic appreciation is looked at with respect to domain generality and domain specificity. Within the classic cognitive paradigm, modality- and domain-specific receptive processes are explored. These are then complemented with central processing structures. These reveal domain-specific as well as domain-general processing. Extending the classic cognitive science approach, the role of emotion in aesthetic appreciation is also explored. While domain-specific models of aesthetic appreciation are clearly called for, there are also numerous domain-general subprocesses and structures.     

Poor working memory predicts false memories

Two studies investigated whether individual differences in simple span verbal working memory and complex working memory capacity are related to memory accuracy and susceptibility to false memory development. In Study 1, undergraduate students (N=60) were given two simple span working memory tests: forward and backward digit span. They also underwent a memory task that is known to elicit false memories of nonpresented words, the Deese/Roediger-McDermott (DRM) paradigm. Poor simple span working memory (as reflected by suboptimal backward digit span scores) was related to elevated levels of false recognition. Study 2 (N=65) replicated this finding, in that suboptimal backward digit span performance was found to be predictive of false recognition. However, complex working memory capacity (operation span) was not related to false recognition. This pattern suggests that even in a homogenous sample of undergraduates, poor working memory is associated with the susceptibility to recollect words never presented.     

Evolutionary consumer psychology: Ask not what you can do for biology,but…

The commentaries raise questions about modularity, and about the evidence required to establish evolutionary influences on behavior. We briefly discuss evidence leading evolutionary psychologists to assume that human choices reflect evolutionary influences, and to assume some degree of modularity in human information processing. An evolutionary perspective is based on a multidisciplinary nomological network of evidence, and results of particular experiments are only one part of that network. The precise nature of, and number of, information processing systems, is an empirical question. Consumer psychologists need not retrain as biologists to profit from using insights and findings from evolutionary biology to generate new hypotheses, and to contribute novel insights and findings to the emerging nomological network of modern evolutionary science.     

Efficient spatio-temporal data mining with GenSpace graphs

We describe a method for spatio-temporal data mining based on GenSpace graphs. Using familiar calendar and geographical concepts, such as workdays, weeks, climatic regions, and countries, spatio-temporal data can be aggregated into summaries in many ways. We automatically search for a summary with a distribution that is anomalous, i.e., far from user expectations. We repeatedly ranking possible summaries according to current expectations, and then allow the user to adjust these expectations. We also choose a propagation path in the GenSpace subgraph that reduces the storage and time costs of the mining process.     

Relative accessibility of domain knowledge and creativity: The effects of knowledge activation on the quantity and originality of generated ideas

In brainstorming research, quantity is assumed to breed quality. However, little is known about the cognitive mechanisms underlying this relationship. A parsimonious explanation assumes a random process, in which every idea has an equal chance of being a high-quality (original and feasible) idea. In contrast, a ‘deep exploration’ approach suggests that the originality (but not the feasibility) of generated ideas is dependent on the degree to which people engage in deep exploration of their knowledge. We conducted two experiments to test the latter hypothesis. Prior to a brainstorming task, participants were primed with subcategories of the brainstorming topic. Priming caused a higher relative productivity and average originality within the primed subcategory, but did not affect global productivity and originality across categories. This effect was replicated in dyadic interactions. These results support the deep exploration hypothesis, and suggest that the relationship between quantity and quality is more complex than has previously been assumed.     

Domain specificity versus expertise: factors influencing distinct processing of faces

To explore face specificity in visual processing, we compared the role of task-associated strategies and expertise on the N170 event-related potential (ERP) component elicited by human faces with the ERPs elicited by cars, birds, items of furniture, and ape faces. In Experiment 1, participants performed a car monitoring task and an animacy decision task. In Experiment 2, participants monitored human faces while faces of apes were the distracters. Faces elicited an equally conspicuous N170, significantly larger than the ERPs elicited by non-face categories regardless of whether they were ignored or had an equal status with other categories (Experiment 1), or were the targets (in Experiment 2). In contrast, the negative component elicited by cars during the same time range was larger if they were targets than if they were not. Furthermore, unlike the posterior-temporal distribution of the N170, the negative component elicited by cars and its modulation by task were more conspicuous at occipital sites. Faces of apes elicited an N170 that was similar in amplitude to that elicited by the human face targets, albeit peaking 10 ms later. As our participants were not ape experts, this pattern indicates that the N170 is face-specific, but not specie-specific, i.e. it is elicited by particular face features regardless of expertise. Overall, these results demonstrate the domain specificity of the visual mechanism implicated in processing faces, a mechanism which is not influenced by either task or expertise. The processing of other objects is probably accomplished by a more general visual processor, which is sensitive to strategic manipulations and attention.     

Applying Research Domain Criteria to the study of emotion dysregulation in infancy and early childhood

Emotion regulation is a principal task of early development. The failure to develop effective emotion regulation skills is associated with behavioural, academic, psychological and socioemotional difficulties. Although researchers have studied emotion regulation for decades, work on emotion dysregulation—defined as the inability to maintain emotional control, engage with the environment or recover from distress in a developmentally appropriate manner—is rare and there are discrepancies in its conceptualisation among very young samples. While some scientists refer to emotion dysregulation as if it were a discrete concept, it may be more accurately depicted as a multidimensional system of developmental processes. The National Institute of Mental Health's Research Domain Criteria (RDoC) is a framework that allows researchers to track dysfunction across multiple areas of analysis and may be an ideal system for exploring the multidimensional nature of infant emotion dysregulation. In this paper, we draw on empirical studies to describe how the RDoC framework can be used to support studies of emotion dysregulation in infancy. This proposed model can also serve as a roadmap for future researchers to follow to generate the evidence base for a multidimensional conceptualisation of infant emotion dysregulation and its underlying mechanisms.     

Advancing measurement of work and family domain boundary characteristics

Recent research offers promising theoretical frameworks for thinking about the work–family interface in terms of the boundaries individuals develop around work and family. However, measures for important constructs proposed by these theories are needed. Using two independent samples, we report on the refinement of existing boundary flexibility measures. Additionally, inter-domain transitions are introduced as a theoretically sound conceptualization of the frequency with which the work and family domains come in contact. Results from Study 1 further support the existence of two flexibility factors, willingness and ability, for the work and family domains, respectively. Results from Study 2 provide evidence for the nomological network surrounding the flexibility and inter-domain transitions measures in relation to role centrality, perceptions of domain blurring, and family-supportive organizational perceptions. Also, as hypothesized, boundary flexibility predicted inter-domain transitions, and inter-domain transitions predicted work–family conflict, with additional support for several hypothesized mediated effects between these constructs.     

The Effects of Domain Knowledge and Instructional Manipulation on Creative Idea Generation

The experiment was designed to explore the effects of domain knowledge, instructional manipulation, and the interaction between them on creative idea generation. Three groups of participants who respectively possessed the domain knowledge of biology, sports, or neither were asked to finish two tasks: imagining an extraterrestrial animal and creating a new sport. Participants in each group were randomly assigned to one of three instructions, in order to encourage them to perform the tasks using a specific instance strategy (relying on specific instances), an abstract strategy (relying on abstract principles), or their habitual ways. Based on an analysis of the participants' verbal reports and their creations, the results suggested that domain knowledge enhanced the tendency to use the abstract strategy, and improved the originality and practicality of the generated ideas. Instructions also influenced the strategy participants used in creative idea generation. The instruction to use abstract principles brought forth the most original creations. Moreover, there was an interaction between domain knowledge and instructions. Encouraging participants to use the specific instance strategy blocked the knowledgeable people from developing novel ideas. Other factors, such as age, grade and gender, were found to be unrelated to either the originality or the practicality of the creations. The implications of the results were discussed in detail.
