The role of partners for employees' recovery during the weekend

We examined the effects of positive and negative experiences with the partner (absorption in joint activities and conflict with the partner) during the weekend on affective states at the beginning of the following work week and tested whether recovery experiences (psychological detachment, relaxation, and mastery experiences) mediated these effects. In total, 269 university faculty members completed online surveys before and after the weekend. Hierarchical regression analyses revealed that absorption in joint activities with the partner predicted recovery experiences during the weekend and increased positive affective states (vigor, joviality, serenity) at the beginning of the following work week. Relaxation mediated the effects of absorption in joint activities on positive affective states. Conflict with the partner increased negative affective states (negative activation, fatigue), but was unrelated to recovery experiences. Our findings emphasize the importance of experiences with the partner for employees' recovery and show that the social environment of employees matters for their recovery.     

Mapping the tip of the tongue--deprivation, sensory sensitisation, and oral haptics

We investigated the impact of food deprivation on oral and manual haptic size perception of food and non-food objects. From relevant theories (need-proportional perception, motivated perception, frustrative nonreward, perceptual defence, and sensory sensitisation) at least four completely different competing predictions can be derived. Testing these predictions, we found across four experiments that participants estimated the length of both non-food and food objects to be larger when hungry than when satiated, which was true only for oral haptic perception, while manual haptic perception was not influenced by hunger state. Subjectively reported hunger correlated positively with estimated object size in oral, but not in manual, haptic perception. The impact of food deprivation on oral perception vanished after oral stimulations even for hungry individuals. These results favour a sensory sensitisation account maintaining that hunger itself does not alter oral perception but the accompanying lack of sensory stimulation of the oral mucosa. Both oral and manual haptic perception tended to underestimate actual object size. Finally, an enhancing effect of domain-target matching was found, ie food objects were perceived larger by oral than by manual haptics, while non-food objects were perceived larger by manual than by oral haptics.     

The next generation of psychological autopsy studies: part 2. Interview procedures

The psychological autopsy (PA) is a systematic method of assessing the psychological and contextual circumstances preceding suicide. The method requires interviews with one or more proxy respondents (i.e., informants) of suicide decedents. Procedural challenges that need to be addressed to conduct PA interviews are described in this article and recommendations for meeting these challenges in future PA investigations are made. Procedures addressed include determining the timing of PA interviews after suicide, designing the structure and flow of interviews, selection of proxy respondents, integrating interview data with information gathered from records, and selecting and training interviewers. This methodological article is the second in a two-part series-the first article focused on interview content.     

How Contextual Frames Normalize Submission

ABSTRACT

Two studies demonstrate how contextual frames normalize submission and hereby complement and legitimize the exercise of power. Combining Kuhn’s qualitative concept of the self with Charles Osgood’s empirical measurements of self-attitudes, the first study tests the impact of the frame of submission on self-attitudes. This assessment of the self allows to quantify the influence of a frame or context. A second study tests the hypothesis that selves, organized by the context of submission, will normalize acts of submission. Computer simulations that quantitatively operationalize the Cybernetic Symbolic Interactionist perspective, find evidence for the normalizing quality of frames.     

Usability,aesthetics and emotions in human–technology interaction

In the past, research on human–technology interaction has almost exclusively concentrated on aspects of usefulness and usability. Despite the success of this line of research, its narrow perspective has recently become a target for criticism. To explain why people prefer some systems over others, factors such as aesthetic qualities and emotional experiences play an important role in addition to instrumental aspects. In the following, we report three experiments that illustrate the importance of such factors. In the first experiment, we study the role of emotions in human–technology interaction by using Scherer's ( 1984 1984) component theory of emotions as a theoretical foundation. A combination of methods is derived from that theory and employed to measure subjective feelings, motor expressions, physiological reactions, cognitive appraisals, and behaviour. The results demonstrate that the manipulation of selected system properties may lead to differences in usability that affect emotional user reactions. The second experiment investigates the interplay of instrumental and non-instrumental system qualities. The results show that users' overall appraisal of a technical device is influenced by both groups of qualities. In the third experiment, we join the approaches of the first two studies to analyse the influence of usability and aesthetics within a common design. The results indicate that systems differing in these aspects affect the perception of instrumental and non-instrumental qualities as well as the users' emotional experience and their overall appraisal of the system. Summarizing our results, we present a model specifying three central components of user experience and their interrelations (CUE-Model). The model integrates the most important aspects of human–technology interaction and hints at a number of interesting issues for future research.
