Why Research-Oriented Design Isn’t Design-Oriented Research: On the Tensions Between Design and Research in an Implicit Design Discipline

Human–computer interaction (HCI) is the discipline concerned with the design, evaluation, and implementation of interactive computing systems. Unlike many empirical sciences, HCI researchers do not typically solely study existing technologies, styles of interaction, or interface solutions. On the contrary, one of the core activities in contemporary HCI is to design new technologies – in the form of software and hardware prototypes – that act as vehicles through which HCI researchers’ ideas materialize and take on concrete form. Despite this situation, there is a very modest discussion in the discipline on the role of design as an activity in the research process; whether or not HCI could in fact be better understood as a design discipline than as an empirical science; and if, and if so how, the design element in HCI goes with its empirical claims. This paper is specifically about the element of design as currently manifest in HCI research. We dig deeper into HCI as a design discipline by suggesting, analyzing, and discussing what appear to be tensions between two competing traditions in the relationship between design and research.

Five Key Topics on the Frontier of Theology and Science Today

Abstract : This article explores the creative mutual interaction between Christian theology and the natural sciences through five key issues: (1) the relation between creation ex nihilo and Big Bang cosmology; (2) biological evolution and continuous creation; (3) the search for non‐interventionist objective divine action in light of physics and biology; (4) the problem of suffering in nature and with it the turn to redemption theology via the bodily Resurrection of Jesus; and (5) the challenge raised for its eschatological implications by scientific predictions for the future of the universe. The article concludes with a brief suggestion for the ways Christian theology, reformulated in light of these sciences, might offer creative suggestions for future scientific research, and, in doing so, complete the loop promised by the phrase “mutual creative interaction.”     

Multiple Determinants of Externalizing Behavior in 5-Year-Olds: A Longitudinal Model

In a community sample of 116 children, assessments of parent-child interaction, parent-child attachment, and various parental, child, and contextual characteristics at 15 and 28 months and at age 5 were used to predict externalizing behavior at age 5, as rated by parents and teachers. Hierarchical multiple regression analysis and path analysis yielded a significant longitudinal model for the prediction of age 5 externalizing behavior, with independent contributions from the following predictors: child sex, partner support reported by the caregiver, disorganized infant-parent attachment at 15 months, child anger proneness at 28 months, and one of the two parent-child interaction factors observed at 28 months, namely negative parent-child interactions. The other, i.e., a lack of effective guidance, predicted externalizing problems only in highly anger-prone children. Furthermore, mediated pathways of influence were found for the parent-child interaction at 15 months (via disorganized attachment) and parental ego-resiliency (via negative parent-child interaction at 28 months).

What can make the difference? Premature birth and maternal sensitivity at 3 months of age: the role of attachment organization, traumatic reaction and baby's medical risk

The influence of prematurity and maternal attachment organization on sensitivity was investigated in 40 mother–infant dyads. Results show a main effect of attachment and an interaction between attachment and prematurity. Sensitivity was differently associated with medical risk and mothers’ traumatic reaction, depending on the quality of attachment.     

Rocking together: dynamics of intentional and unintentional interpersonal coordination

The current study investigated the interpersonal coordination that occurred between two people when sitting side-by-side in rocking chairs. In two experiments participant pairs rocked in chairs that had the same or different natural periods. By instructing pairs to coordinate their movements inphase or antiphase, Experiment 1 investigated whether the stable patterns of intentional interpersonal coordination were consistent with the dynamics of within person interlimb coordination. By instructing the participants to rock at their own preferred tempo, Experiment 2 investigated whether the rocking chair movements of visually coupled individuals would become unintentionally coordinated. The degree to which the participants fixated on the movements of their co-actor was also manipulated to examine whether visual focus modulates the strength of interpersonal coordination. As expected, the patterns of coordination observed in both experiments demonstrated that the intentional and unintentional interpersonal coordination of rocking chair movements is constrained by the self-organizing dynamics of a coupled oscillator system. The results of the visual focus manipulations indicate that the stability of a visual interpersonal coupling is mediated by attention and the degree to which an individual is able to detect information about a co-actor's movements.     

The effects of bilateral presentations on lateralized lexical decision

We investigated how lateralized lexical decision is affected by the presence of distractors in the visual hemifield contralateral to the target. The study had three goals: first, to determine how the presence of a distractor (either a word or a pseudoword) affects visual field differences in the processing of the target; second, to identify the stage of the process in which the distractor is affecting the decision about the target; and third, to determine whether the interaction between the lexicality of the target and the lexicality of the distractor ("lexical redundancy effect") is due to facilitation or inhibition of lexical processing. Unilateral and bilateral trials were presented in separate blocks. Target stimuli were always underlined. Regarding our first goal, we found that bilateral presentations (a) increased the effect of visual hemifield of presentation (right visual field advantage) for words by slowing down the processing of word targets presented to the left visual field, and (b) produced an interaction between visual hemifield of presentation (VF) and target lexicality (TLex), which implies the use of different strategies by the two hemispheres in lexical processing. For our second goal of determining the processing stage that is affected by the distractor, we introduced a third condition in which targets were always accompanied by "perceptual" distractors consisting of sequences of the letter "x" (e.g., xxxx). Performance on these trials indicated that most of the interaction occurs during lexical access (after basic perceptual analysis but before response programming). Finally, a comparison between performance patterns on the trials containing perceptual and lexical distractors indicated that the lexical redundancy effect is mainly due to inhibition of word processing by pseudoword distractors.     

Effects of bilateral eye movements on gist based false recognition in the DRM paradigm

The effects of saccadic bilateral (horizontal) eye movements on gist based false recognition was investigated. Following exposure to lists of words related to a critical but non-studied word participants were asked to engage in 30s of bilateral vs. vertical vs. no eye movements. Subsequent testing of recognition memory revealed that those who undertook bilateral eye movement were more likely to correctly recognise previously presented words and less likely to falsely recognise critical non-studied associates. This result joins other research in demonstrating the conditions in which false memory effects can be attenuated.     

Family Interactions in Children With and Without ADHD

We used global ratings to compare the family (parent[s]-child) interactions of 51 clinic-referred children with ADHD and 32 non problem children. Children and parent(s) were videotaped while engaging in problem solving and game playing activities. Independent coders, blind to children's diagnostic status, rated the interactions using measures designed to assess interaction competence and quality. Significant group differences emerged between the ADHD and control groups during problem solving on the interaction quality measures of Warmth, Engagement and Communication. Comparisons of the interactions of families of children with ADHD, with (ADHD W) and without (ADHD W/O) comorbid disruptive behavior disorders, were non significant, although increased symptomology was associated with reduced Warmth and Engagement during problem solving. Irrespective of group membership family interactions were more positive during game playing versus problem solving.
