- In response to the COVID-19 pandemic, the Psychological Science Accelerator coordinated three large-scale psychological studies to examine the effects of loss-gain framing, cognitive reappraisals, and autonomy framing manipulations on behavioral intentions and affective measures. The data collected (April to October 2020) included specific measures for each experimental study, a general questionnaire examining health prevention behaviors and COVID-19 experience, geographical and cultural context characterization, and demographic information for each participant. Each participant started the study with the same general questions and then was randomized to complete either one longer experiment or two shorter experiments. Data were provided by 73,223 participants with varying completion rates. Participants completed the survey from 111 geopolitical regions in 44 unique languages/dialects. The anonymized dataset described here is provided in both raw and processed formats to facilitate re-use and further analyses. The dataset offers secondary analytic opportunities to explore coping, framing, and self-determination across a diverse, global sample obtained at the onset of the COVID-19 pandemic, which can be merged with other time-sampled or geographic data.

- Over the past 10 years, Oosterhof and Todorov's valence-dominance model has emerged as the most prominent account of how people evaluate faces on social dimensions. In this model, two dimensions (valence and dominance) underpin social judgements of faces. Because this model has primarily been developed and tested in Western regions, it is unclear whether these findings apply to other regions. We addressed this question by replicating Oosterhof and Todorov's methodology across 11 world regions, 41 countries and 11,570 participants. When we used Oosterhof and Todorov's original analysis strategy, the valence-dominance model generalized across regions. When we used an alternative methodology to allow for correlated dimensions, we observed much less generalization. Collectively, these results suggest that, while the valence-dominance model generalizes very well across regions when dimensions are forced to be orthogonal, regional differences are revealed when we use different extraction methods and correlate and rotate the dimension reduction solution.

Tactile prosthetics in WiseSkin
- 2015
-
Ingår i: Proceedings of the 2015 Design, Automation and Test in Europe Conference and Exhibition, DATE 2015. - 9783981537048 ; 2015-April, s. 1695-1697

- The use of prosthetic hands is limited in part by the lack of sensory feedback to the wearer. In order to provide sensory feedback, an adequate number of sensors must be integrated with the prosthesis. The WiseSkin project targets the use of artificial skin embedding ultra-low power wireless sensor nodes. This presentation provides an overview of the WiseSkin project and the current status of the developments.

The Psychological Science Accelerator: Advancing Psychology Through a Distributed Collaborative Network
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Concerns about the veracity of psychological research have been growing. Many findings in psychological science are based on studies with insufficient statistical power and nonrepresentative samples, or may otherwise be limited to specific, ungeneralizable settings or populations. Crowdsourced research, a type of large-scale collaboration in which one or more research projects are conducted across multiple lab sites, offers a pragmatic solution to these and other current methodological challenges. The Psychological Science Accelerator (PSA) is a distributed network of laboratories designed to enable and support crowdsourced research projects. These projects can focus on novel research questions or replicate prior research in large, diverse samples. The PSA’s mission is to accelerate the accumulation of reliable and generalizable evidence in psychological science. Here, we describe the background, structure, principles, procedures, benefits, and challenges of the PSA. In contrast to other crowdsourced research networks, the PSA is ongoing (as opposed to time limited), efficient (in that structures and principles are reused for different projects), decentralized, diverse (in both subjects and researchers), and inclusive (of proposals, contributions, and other relevant input from anyone inside or outside the network). The PSA and other approaches to crowdsourced psychological science will advance understanding of mental processes and behaviors by enabling rigorous research and systematic examination of its generalizability.

Design and evaluation of miniaturized solenoid actuators for providing sensory feedback for upper limb amputee
- 2018

- Losing a hand or arm can dramatically degrade life quality of an amputee. Although the development of advanced prosthesis has made significant progress, the prosthesis abandon rate is reported high (30% and 50%). One of the major reasons for prosthesis abandonment is the lack of sensory feedback. Providing sensory feedback can not only increase the functionality of the prostheses, but also introduce a body ownership feeling to the amputees. In current work, a miniaturized solenoid device was designed and integrated in the prosthetic socket for providing grasping force feedback for upper limb amputees. The sensory feedback system was tested with one amputee subject and proved to be useful for deformability detection and objective manipulation.

Eliciting intelligence from sources informed about counter-interrogation strategies: An experimental study on the Scharff technique
- 2020
-

Tidskriftsartikel (refereegranskat)abstract
- The Scharff technique aims to elicit information by affecting the source's perception of the interviewer's existing knowledge. Although the technique has been found to be effective for gathering new information, countermeasures to the technique have not been examined. In a 2 x 2 between-subjects experiment, we informed half of the 120 sources about the counter-interrogation strategy of carefully considering the interviewer's prior knowledge and the tactic of providing information perceived as already known to the interviewer. After this, sources were interviewed with the Scharff technique or the Direct approach, widely used in human intelligence-gathering situations and consisting of open-ended and direct questions. We found that "informed sources" did not succeed in revealing information already known to the interviewer, where informed sources and uninformed sources revealed known information to a similar degree (1.62 pieces vs. 1.65 pieces). Sources interviewed with the Direct approach (vs. Scharff technique) revealed a larger amount of information previously known to the interviewer (2.18 pieces vs. 1.08 pieces). When interviewed with the Scharff technique, sources informed about the counter-interrogation strategy attempted to adopt more counter-interrogation strategies. The present study replicates earlier research on the Scharff technique as a technique effective in affecting the source's perception of the interviewer's prior knowledge. The results of the current study indicate that both the Scharff technique and the Direct approach might be similarly robust against counter-interrogation strategies, in terms of gathering new information. Future studies should focus on implementing more comprehensive training in counter-interrogation strategies for the sources.

Gene-Environment Correlation Between the Dopamine Transporter Gene (DAT1) Polymorphism and Childhood Experiences of Abuse

- In the present study, we investigated the possible gene-environment correlation between the dopamine transporter gene (DAT1) polymorphism and childhood experiences of abuse and neglect. Genetic information was obtained from 1,442 male and 2,178 female twins and their siblings drawn from a Finnish population-based sample. The Childhood Trauma Questionnaire was used to measure the childhood experiences of abuse and neglect. In men, the DAT1 polymorphism was associated with having experienced sexual abuse in childhood, such that men with the 9R9R genotype reported less sexual abuse experiences than men with the 9R10R or the 10R10R genotypes. In women, there was an association between the DAT1 polymorphism and childhood experiences of emotional abuse, such that women with the 9R9R genotype reported less emotional abuse experiences than women with the 9R10R or 10R10R genotypes. No other associations between the DAT1 polymorphism and childhood experiences of abuse and neglect were found. In sum, the results suggested that some genetic components might predispose children to experience childhood abuse and neglect. Possible reasons for this association were discussed.
