“…The standard gain length measurement procedure in LCLS-I employs such kicks in order to terminate the interaction at a given location and record the corresponding radiation pulse energy. Other applications include schemes such as the DELTA variable polarization undulator [7] (where different polarization components are separated by means of an angular kick to the bunched e-beam) or proposed fast gain length measurement techniques using energy-loss data from kicked beams [8].…”

“…Furthermore, these elements can represent reference points around which the mental representation of the route is built, just like environmental landmarks [ 1 , 2 ]. For this reason, studies suggest that the emotional salience of landmarks is a key dimension to consider when investigating how individuals represent environmental spatial information [ 3 , 4 ]. However, the influence of both valence and arousal of these elements on the mental representations of a route has hardly been explored [ 5 ].…”

The Influence of Stimuli Valence and Arousal on Spatio-Temporal Representation of a Route

This study assesses the influence of valence and arousal of element/landmarks along a route on the spatio-temporal representation of the route itself. Participants watched a movie of a virtual route containing landmarks with high arousal and positive (HP) or negative valence (HN), or landmarks with low arousal and positive (LP) or negative valence (LN). Afterwards, they had to (a) imagine walking distances between landmarks, (b) indicate the position of the landmarks along the route, (c) judge the spatial and temporal length of the route, and (d) draw the route. Results showed that the tasks were differentially influenced by the valence and arousal levels. Specifically, participants were more accurate in representing distances between positive, rather than negative, landmarks and in localizing positive high arousing landmarks. Moreover, the high arousing landmarks improved performance at the route drawing task. Finally, participants in the negative and low arousing conditions judged the route as being metrically and temporally longer than participants in positive and high arousing conditions. These results are interpreted in the light of theories about the effects of emotions on memory processes and the “feelings-as-information” theory. In brief, the results support the idea that representations of a route reflect a combination of cognitive and emotional processes.

“…They are visually prominent, structurally significant, and salient [ 60 , 61 ]. They are characterized by a certain shape (they are extended in the space), visible from the pathway, with a leisure meaning (a beach with a seaside pathway and the city largest urban park, respectively), fundamental qualities contributing to their strong place identity [ 62 ]. They can be qualified as visually, semantically, and structurally attractive [ 63 ] and they are frequented by the elderly as meeting and socialization places.…”

Studying Individual Differences in Spatial Cognition Through Differential Item Functioning Analysis

et al. 2020

Background: In the field of spatial cognition, the study of individual differences represents a typical research topic. Gender and age have been prominently investigated. A promising statistical technique used to identify the different responses to items in relation to different group memberships is the Differential Item Functioning Analysis (DIF). The aim of the present study was to investigate the DIF of the Landmark positioning on a Map (LPM) task, across age groups (young and elderly) and gender, in a sample of 400 healthy human participants. Methods: LPM is a hometown map completion test based on well-known and familiar landmarks used to assess allocentric mental representations. DIF was assessed on LPM items two times: on categorical (i.e., positions) and coordinate (i.e., distances) scores, separately. Results: When positions and distances were difficult to assess with respect to the intended reference point, the probability to endorse the items seemed to get worse for the elderly compared to the younger participants. Instead other features of landmarks (high pleasantness, restorativeness) seemed to improve the elderly performance. A gender-related improvement of probability to endorse distance estimation of some landmarks, favoring women, emerged, probably associated with their repeated experiences with those landmarks. Overall, the complexity of the task seemed to have a differential impact on young and elderly people while gender-oriented activities and places seemed to have a differential impact on men and women. Conclusions: For the first time DIF was applied to a spatial mental representation task, based on the schematic sketch maps of the participants. The application of DIF to the study of individual differences in spatial cognition should become a systematic routine to early detect differential items, improving knowledge, as well as experimental control, on individual differences.
