Sensory processing sensitivity, memory and cognitive training with neurofeedback

Sensory processing sensitivity (SPS) is a biological trait associated with enhanced awareness of and responsivity to the environment, as well as depth of cognitive processing. However, only a few studies have investigated how contextual factors impact cognition as a function of SPS. Thus, this study examined whether SPS is associated with differential changes in cognitive function resulting from participation in a 4-week app-based cognitive training program with neurofeedback (CT-NF). Participants (M age = 66 years) were randomized to either a treatment (CT-NF) or control group (Tetris). They completed a self-report measure of SPS (the Highly Sensitive Person Scale), and cognitive tests at pre- and post–intervention. Results revealed that individuals with higher levels of SPS in the treatment group showed superior improvements in memory (MEM) and visual memory (VSM), relative to other participants and other measures of cognition. These findings are consistent with theories of SPS and studies showing that enhanced visual perceptiveness and memory are associated with the trait. Moreover, they highlight the cognitive mechanisms that might be especially important for SPS. In conclusion, these findings suggest that those with high SPS may experience enhancements in MEM and VSM, resulting from a 4-week app-based CT-NF program.

Using Eye-Tracking Methodology to Study Grid Question Designs in Web Surveys

Abstract Grid questions are frequently employed in web surveys due to their assumed response efficiency. In line with this, many previous studies have found shorter response times for grid questions compared to item-by-item formats. Our contribution to this literature is to investigate how altering the question format affects response behavior and the depth of cognitive processing when answering both grid question and item-by-item formats. To answer these questions, we implemented an experiment with three questions in an eye-tracking study. Each question consisted of a set of ten items which respondents answered either on a single page (large grid), on two pages with five items each (small grid), or on ten separate pages (item-by-item). We did not find substantial differences in cognitive processing overall, while the processing of the question stem and the response scale labels was significantly higher for the item-by-item design than for the large grid in all three questions. We, however, found that when answering an item in a grid question, respondents often refer to surrounding items when making a judgement. We discuss the findings and limitations of our study and provide suggestions for practical design decisions.

Facilitating Online Learning Communities: A Comparison of Two Discussion Facilitation Techniques

ABSTRACT The advent of the twenty-first century has brought a proliferation of web-based courses in higher education. While prior studies have examined the comparability of online and traditional courses, a better understanding of effective pedagogical strategies to enhance online learning is needed. This study compared two distinct approaches to facilitating discussions in relation to participation rates, interaction patterns, depth of cognitive processing, and learning outcomes in two sections of an online course. Significant differences were found between sections (N = 41) in the frequency and types of interaction among students as well as in learning outcomes.

Eye-Movement Parameters and Perceived Map Complexity—II

In part I of this study, it was concluded (Castner and Eastman 1984) that eye movements are an outward manifestation of visual/cognitive processing, and that studies of how, rather than where, the eye moves might prove useful in map-design experiments. Two eye-movement parameters, fixation duration (indicating depth of cognitive processing) and interfixation distance (indicating extent of peripheral processing) reflect the ease with which a display's information can be assimilated. In part II, we describe a twelve-map experiment that confirms the hypothesized correlation between perceived complexity (assessed by 38 subjects) and imageability (indicated by the fixation durations and interfixation distances of 22 subjects), demonstrating the value of eye-movement studies in assessing the holistic properties of maps.
