Gaze position regulates memory accessibility during competitive memory retrieval
- 2020
-
Ingår i: Cognition. - : Elsevier BV. - 0010-0277. ; 197
-
Tidskriftsartikel (refereegranskat)abstract
- While previous research has demonstrated that gaze position can increase the accessibility of previous memories when reconstructing the past (Johansson & Johansson, 2014), the present study tested whether such gaze behavior can assist in selecting target memories in the face of competing memories. An adapted retrieval practice paradigm was used, where participants were engaged in selective retrieval while looking at locations that overlapped with the encoding location of either the target item or the competing item. Replicating previous findings, we show that encoding-retrieval compatibility in gaze positions increases the likelihood of successful remembering. We furthermore provide novel evidence that looking at locations where competing items were encoded during retrieval practice induces forgetting of the competitors during subsequent tests of memory. Corroborating evidence from changes in pupil size suggests that such gaze induced forgetting is modulated by the increased demands to successfully resolve interference from competing memories. This study represents the first demonstration that gaze position can both up- and downregulate memory accessibility during competitive memory retrieval and offers novel insights into the underlying dynamics.

How encoding-retrieval overlap in gaze positions influences episodic memory accessibility in the “real world”
- 2020
-
Konferensbidrag (refereegranskat)abstract
- An extensive body of research has shown that episodic remembering involves spontaneous eye movements that largely reproduce the gaze patterns that were present during encoding (e.g. Brandt & Stark, 1997; Johansson, et al., 2006; 2012; Johansson & Johansson, 2014; Richardson & Spivey, 2000). We have further demonstrated that gaze positions showing compatibility between encoding and retrieval increase the likelihood of successful remembering (Johansson & Johansson, 2014, 2020). However, to date, there is virtually no research on how gaze direction influences episodic remembering outside the laboratory. The aim of the present project was, therefore, to systematically investigate this effect in a “real-world” scenario. In a first experiment, participants (N=40, equipped with a mobile eye tracker) entered a room where they were faced with six framed stimuli at six different locations. Each stimulus comprised a letter in the center and an associated item to the left or right side of this letter. Participants were given 60 s to freely inspect and encode how each letter was associated with the items’ three features (shape, color and location). Participants then exited the room and engaged in a two-minute distracter task before they re-entered the room. They were now faced with the six frames again, but this time only the letter cue was present. They were then given 90 s to orally recall the associated items’ features in a free-recall procedure. For each participant, the same encoding-retrieval procedure was repeated over four rounds. During retrieval, the framed letters were either located in the same location as they were encoded in (congruent) or shuffled around to different locations (incongruent). Results overall replicated our previous lab-finding, with superior retrieval performance in the congruent condition. However, the effect was virtually absent for the participants who faced an incongruent condition in their first round of retrieval. In four follow-up experiments, we manipulated the number of congruent and incongruent frames within trials over the four rounds (0, 2, 4 or 6 congruent frames) and also introduced different degrees of interference between associated items. Interference was created by using two exemplars of each shape and each color instead of using unique shapes and unique colors across stimuli frames. In effect, this creates a situation where there are overlapping and competing features between items across frames. Collectively, the results from those follow-up experiments revealed that the congruency benefit is dependent on both contextual expectation and the need to handle interference from competing memories. Specifically, we show that the expectation of how relevant the spatial context is for the retrieval task can be both up- and down-regulated depending on previous rounds and that the congruency effect increases in accordance with the need to handle interference from competing memories. Those findings are further qualified by data from participants’ gaze patterns. In sum, we extend previous work by demonstrating that facilitatory effects of gaze direction on episodic remembering generalize to “real-world” scenarios, and we present novel findings that shed light on the underlying mechanisms.

Tidskriftsartikel (refereegranskat)abstract
- Human consumption of fruits and vegetables are generally below recommended levels. Waste from the production, e.g., of un-used parts such as broccoli leaves and stem when producing broccoli florets for food, is a sustainability issue. In this study, broccoli leaves were analyzed for the content of various dietary fibre and phenolics, applying the Uppsala method and HPLC analyses, respectively. The results showed that broccoli leaves had comparable levels of dietary fibre (26%-32% of dry weight (DW)) and phenolic compounds (6.3-15.2 mg/g DW) to many other food and vegetables considered valuable in the human diet from a health perspective. A significant positive correlation was found among soluble dietary fibre and phenolic acids indicating possible bindings between these components. Seasonal variations affected mainly the content of conjugated phenolics, and the content of insoluble dietary fibre. This study verified the importance of the use of broccoli production side streams (leaves) as they may contribute with health promoting components to the human diet and also socio-economic and environmental benefits to the bioeconomic development in the society.

Subpopulations of extracellular vesicles from human metastatic melanoma tissue identified by quantitative proteomics after optimized isolation
- 2020
-
Ingår i: Journal of Extracellular Vesicles. - : Wiley. - 2001-3078. ; 9:1

Tidskriftsartikel (refereegranskat)abstract
- The majority of extracellular vesicle (EV) studies conducted to date have been performed on cell lines with little knowledge on how well these represent the characteristics of EVs in vivo. The aim of this study was to establish a method to isolate and categorize subpopulations of EVs isolated directly from tumour tissue. First we established an isolation protocol for subpopulations of EVs from metastatic melanoma tissue, which included enzymatic treatment (collagenase D and DNase). Small and large EVs were isolated with differential ultracentrifugation, and these were further separated into high and low-density (HD and LD) fractions. All EV subpopulations were then analysed in depth using electron microscopy, Bioanalyzer (R), nanoparticle tracking analysis, and quantitative mass spectrometry analysis. Subpopulations of EVs with distinct size, morphology, and RNA and protein cargo could be isolated from the metastatic melanoma tissue. LD EVs showed an RNA profile with the presence of 18S and 28S ribosomal subunits. In contrast, HD EVs had RNA profiles with small or no peaks for ribosomal RNA subunits. Quantitative proteomics showed that several proteins such as flotillin-1 were enriched in both large and small LD EVs, while ADAM10 were exclusively enriched in small LD EVs. In contrast, mitofilin was enriched only in the large EVs. We conclude that enzymatic treatments improve EV isolation from dense fibrotic tissue without any apparent effect on molecular or morphological characteristics. By providing a detailed categorization of several subpopulations of EVs isolated directly from tumour tissues, we might better understand the function of EVs in tumour biology and their possible use in biomarker discovery.

How the blind audience receive and experience audio descriptions of visual events – a project presentation
- 2020
-
Ingår i: ; , s. 39-41
-
Konferensbidrag (refereegranskat)abstract
- We present a three-year multidisciplinary research project that started in 2019 and is funded by FORTE (Swedish Research Council for Health, Working Life and Welfare). The theoretical aim of the project is to gain a better understanding of the principles that underlie successful communication between the sighted and the blind via audio description (AD). The aim of a series of experiments is to identify similarities and differences in how the sighted and the blind understand, segment and experience visual, spatial as well as temporal properties of an event. The applied goal is to increase the quality of AD and to support the training of audio de-scribers and AD practices, and ultimately facilitate the understanding and accessibility of visual information for the visually impaired.
