Experiencing nearby locations together in time: the role of spatiotemporal contiguity in children's memory for location

Three studies investigated how experiencing nearby locations together in time influences memory for location. Seven-, 9-, and 11-year-old children and adults learned 20 object locations in a small-scale space. The space was divided into regions by lines or walls. In Study 1, participants learned the locations either region by region or in a random order. Following learning, participants replaced the objects without the aid of the dots marking the locations and the boundaries subdividing the space. They replaced the objects in any order they chose. After experiencing the locations in random orders during learning, only adults underestimated distances between locations belonging to the same group (i.e., region). Conversely, 9- and 11-year-old children and adults who had experienced the locations region by region during learning underestimated these distances. These findings suggest that experiencing nearby locations together in time increases the weight children assign to categorical information in their estimates of location. Results from Studies 2 and 3 in which participants learned the locations region by region and then replaced the objects region by region (Study 2) or in a random order (Study 3) were similar, highlighting the importance of spatiotemporal cues in memory for location.

Effects of mask use and other-race on face perception,emotion recognition,and social distancing during the COVID-19 pandemic

We tested the effect of mask use and other-race effect on (a) face recognition, (b) recognition of facial expressions, and (c) social distance. Caucasian subjects were tested in a matching-to-sample paradigm with either masked or unmasked Caucasian and Asian faces. The participants exhibited the best performance in recognizing an unmasked face condition and the poorest to recognize a masked face that they had seen earlier without a mask. Accuracy was poorer for Asian faces than Caucasian faces. The second experiment presented Asian or Caucasian faces having emotional expressions, with and without masks. The participants' emotion recognition performance decreased for masked faces. From the most accurately to least accurately recognized emotions were as follows: happy, neutral, disgusted, fearful. Performance was poorer for Asian stimuli compared to Caucasian. In Experiment 3 the same participants indicated the social distance they would prefer with each pictured person. They preferred a wider distance with unmasked faces compared to masked faces. Distance from farther to closer was as follows: disgusted, fearful, neutral, and happy. They preferred wider social distance for Asian compared to Caucasian faces. Altogether, findings indicated that during the COVID-19 pandemic mask wearing decreased recognition of faces and emotional expressions, negatively impacting communication among people from different ethnicities.     

I need you closer to me: Effects of affiliation goals on perceptions of interpersonal distance

People's perceptions are often distorted in a way that aligns with their desires and goals. We argue that having a goal to affiliate changes the perception of interpersonal distance in a way that may help to fulfil this affiliation goal. As other people are goal‐relevant when having an affiliation goal, we expected that people with affiliation goals would estimate the distance between themselves and another person as smaller than people with no affiliation goals. In two studies, we manipulated affiliation goals by priming participants with affiliation or control words. Our main dependent variable was the estimated interpersonal distance between themselves and the experimenter. Results showed that participants primed with affiliation estimated the interpersonal distance as smaller compared with participants primed with control words. We did not obtain reliable differences between the affiliation and control conditions on other distance and height estimations. Our results suggest that having or not having affiliation goals influences people's perception of the distance between them and other people.     

SNARC (spatial–numerical association of response codes) meets SPARC (spatial–pitch association of response codes): Automaticity and interdependency in compatibility effects

Concepts, including the mental number line, or addressing pitch as high and low, suggest that the spatial–numerical and spatial–pitch association of response codes (SNARC and SPARC) effects are domain-specific and thus independent. Alternatively, there may be dependencies between these effects, because they share common automatic or controlled decision mechanisms. In two experiments, participants were presented with spoken numbers in different pitches; their numerical value, pitch, and response compatibility were varied systematically. This allowed us to study SNARC and SPARC effects in a factorial design (see also Fischer, Riello, Giordano, &; Rusconi, 2013 Fischer, M. H., Riello, M., Giordano, B. L., &; Rusconi, E. (2013). Singing numbers?…?in cognitive space--a dual-task study of the link between pitch, space, and numbers. Topics in Cognitive Science, 5(2), 354–366. Retrieved from http://doi.org/10.1111/tops.12017[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Participants judged the stimuli on numerical magnitude, pitch, or parity (odd–even). In all tasks, the SNARC and SPARC effects had superadditive interactions. These were interpreted as both effects sharing a common mechanism. The task variation probes the mechanism: In the magnitude judgement task, numerical magnitude was explicit, whereas pitch was implicit; in the pitch judgement task, it was vice versa. In the parity judgement task, both dimensions were implicit. Regardless of whether they were implicit or explicit, both SNARC and SPARC effects occurred in all tasks. We concluded that by not requiring focal attention the common mechanism operates automatically.     

Seeing Like a Geologist: Bayesian Use of Expert Categories in Location Memory

Memory for spatial location is typically biased, with errors trending toward the center of a surrounding region. According to the category adjustment model (CAM), this bias reflects the optimal, Bayesian combination of fine‐grained and categorical representations of a location. However, there is disagreement about whether categories are malleable. For instance, can categories be redefined based on expert‐level conceptual knowledge? Furthermore, if expert knowledge is used, does it dominate other information sources, or is it used adaptively so as to minimize overall error, as predicted by a Bayesian framework? We address these questions using images of geological interest. The participants were experts in structural geology, organic chemistry, or English literature. Our data indicate that expertise‐based categories influence estimates of location memory—particularly when these categories better constrain errors than alternative (“novice”) categories. Results are discussed with respect to the CAM.     

领导-成员交换与情绪枯竭:互惠信念和权力距离导向的作用

结合社会交换理论和角色理论,领导-成员交换关系中下属的回报不仅受到互惠规范的约束,还受到上下级关系权力不对称的影响。因此,将探索互惠信念和权力距离导向单独及交互项对领导-成员交换与情绪枯竭关系的调节作用。采用两个时间点172名员工的匹配数据,运用层级回归对假设进行了检验。结果表明,领导-成员交换(T1)与情绪枯竭(T2)总体上呈显著负向关系。互惠信念(T1)和权力距离导向(T1)单独对领导-成员交换与情绪枯竭关系的调节作用并不显著,但是二者的交互项的调节作用显著。即,领导-成员交换、互惠信念和权力距离导向对情绪枯竭有显著三维交互作用。具体的,高互惠信念和低权力距离导向的员工,领导-成员交换与情绪枯竭呈显著正向关系;高互惠信念和高权力距离导向的员工,领导-成员交换与情绪枯竭呈显著负向关系。研究验证了领导-成员交换过程中互惠规范的作用,表明互惠规范的适用性受到上下级关系特征的影响。     

Finger counting habit and spatial–numerical association in children and adults

Sensory-motor experiences are known to build up concrete and abstract concepts during the lifespan. The present study aimed to test how finger counting habits (right-hand vs. left-hand starters) could influence the spatial–numerical representation in number-to-position (explicit) and digit-string bisection (implicit) tasks. The subjects were Italian primary school children (N = 184, from the first to the fifth year) and adults (N = 42). No general preference for right- or left-starting in the finger counting was found. In the explicit task, right- or left-starting did not affect performance. In the implicit task, the right-hand starters shifted from the left to the right space when bisecting small and large numbers respectively, while the left-hand starters shifted from the right to the left space with higher leftward bias for large numbers. The finger configuration in Italian children and adults influences the spatial–numerical representation, but only when implicit number processing is required by the task.
