Robust memory of where from way back when: evidence from behaviour and visual attention

Retention of events typically exhibits a sharp initial decrease followed by levelling off of forgetting. In an apparent exception to this general rule, college students have robust memory for their own locations in obscured versions of photographs of their entering classes taken during orientation-related activities, whether tested 2 months or 42 months after the event. Experiment 1 of the present research was a test for conceptual replication of this finding in photographs depicting more than twice the number of students (and thus potential distracters). There was no difference in memory accuracy for personal spatial location across retention intervals of 6–30 months. Experiment 2 featured 40-h and 2-month retention intervals, thereby providing a more fine-grained test of the forgetting function. The findings replicated Experiment 1. In Experiment 3, eye-tracking measures of visual attention revealed that participants rapidly fixated their own spatial locations within the photographs, even in the absence of explicit awareness. In all three experiments, memory for temporal features of the orientation activities (e.g., day and time the photograph was taken) followed the typical forgetting function. The findings suggest differential preservation of episodic memory for where relative to other aspects of events and experiences, such as when.     

三维图形的客体和空间工作记忆存储机制

采用单探测变化检测范式,通过两个实验探讨了三维双特征图形在视空间工作记忆中的存储方式。实验一的记忆材料为由颜色和形状两种基本特征组成的三维图形,实验二的材料为由基本特征和细节特征组成的三维图形。被试为60名大学本科生（实验1、2各30名,年龄在19~24岁之间,平均21.25岁和21.71岁）。两个实验的结果均显示：特征交换变化条件下的记忆成绩与单一特征变化条件下最小的平均检测正确率无显著差异。这表明,由两种异质特征组成的三维图形在视觉客体和视觉空间工作记忆中均能以整合的单元进行存储。     

Looking the past in the eye: Distortion in memory and the costs and benefits of recalling from an observer perspective

Jordi Fernández (2015) discusses the possible benefits of two types of allegedly distorted memories: observer memories and fabricated memories. Fernández argues that even when memory does not preserve the past, some memories can still provide an adaptive benefit for the subject. I explore Fernández’s claims focussing on the case of observer perspective memories. For Fernández, observer perspectives are distorted memories because they do not preserve past experience. In contrast, I suggest that observer perspectives can accurately reflect past experience: observer perspectives are not necessarily distorted memories. By looking at the complexity of the relation between remembering trauma from an observer perspective and emotional closure, I also sound a note of caution against Fernández’s assertion that observer memories of trauma can be adaptively beneficial. Finally, I suggest that because observer perspectives are not necessarily distorted, but involve a distinct way of thinking about one’s past, such memories can be epistemically beneficial.     

Better understanding the perceptions of organizational politics: its impact under different types of work unit structure

Research has uncovered inconsistent results regarding the influence of the perceptions of organizational politics (POP) on employee job performance, suggesting the existence of boundary conditions for such an influence. Drawing from uncertainty management theory, we investigated the interaction effect of POP and work unit structure on job performance, and examined the mediating role of taking charge. We tested the theoretical model with data gathered across three phases over 6 months from 577 individuals and their supervisors in 133 work units. Results showed that when the unit operated an organic structure, POP was significantly negatively related to job performance. In contrast, results demonstrated that when the unit operated a mechanistic structure, POP was significantly positively related to job performance. Furthermore, the results of the mediated moderation analysis revealed that POP was negatively associated with job performance through taking charge in an organic structure, and the indirect effect disappeared in a mechanistic structure.     

Embodied learning: Teaching sexuality and religion to a changing student body

Sexuality, more so than other subject areas, magnifies the embodied nature of teaching and learning as well as conspicuously silences open dialogue given its taboo status in many religious and theological contexts. Yet, student learning about sexuality that incorporates knowledge of and about religion, in particular, may greatly improve the public discourse about sexuality through our students as responsible citizens and as leaders in their chosen professions. To bridge this gap, through a year‐long collaboration, a group of professors and instructors with expertise and experience teaching sexuality and religion in a variety of disciplines and diverse institutional and religious contexts developed, tested, and refined classroom teaching strategies to shift from a content‐based “subject matter” to an embodied learning experience, resulting in perspective transformation as a primary student‐learning outcome. Findings in the form of “guiding questions,” encourage instructors to attend to contextual, experiential, and performative aspects of the classroom environment.     

Does aging affect the formation of new topographical memories? Evidence from an extensive spatial training

A decline in navigational abilities is a consistent feature of aging. Although many studies focused on recall of navigational information, the impact of time and type of learning on recall has received little attention. We submitted older adults and young participants to an extensive training of an ecological environment, from both route and survey perspectives. Then, we tested participants’ learning using from both route and survey perspectives. Although older adults benefit from the extensive training, they did not reach the same performance of the young participants. Despite this main effect of age, the effect of the type of learning was the same in the two groups. Congruence between type of learning and recall led to better performance in both groups. We discuss these findings in the light of cognitive models of human navigation and aging. Useful suggestions about how these findings may inform a specific cognitive intervention in older adults are also provided.     

Construct validation of the Zimbardo Time Perspectives Inventory

The aim of the present study was to validate the factorial structure and psychometric properties of the Zimbardo Time Perspectives Inventory (ZTPI) in a South African student sample. A total of 200 students completed the ZTPI. The sample comprised 58 0.8% female students. Of these, 61.1% were black students and 38.9% were white students. The average age for the sample was 21.59 years. Exploratory and confirmatory factor analyses were used to examine the construct and discriminant validity of the ZTPI. The data suggest ZTPI to comprise four factors of Present-Fatalistic (PF), Present-Hedonistic (PH), Past-Negative (PN), and Past-Positive (PP). Many of the factors cross-loaded onto one or two others, suggesting poor differentiation in the study sample. Scores from the ZTPI were of acceptable reliability. The study results suggest the ZTPI is usable for research purposes in South Africa.

Magnification rate of objects in a perspective image to fit to our perception

Abstract: A landscape photograph may give a different impression from that formed at the real scene, with respect to the size and distance of objects. Researchers have reported that the perceived sizes and distances of objects in a photograph are not identical to those in a real space. In order to develop a method to create a graphic image that is close to our visual impression as seen in the real space, two experiments were conducted. In Experiment 1, we examined how the magnification rate of the perceived size to the object size on the retina varied with the viewing distance (range was from 1 m to 10 m). In Experiment 2, we examined whether transformation based on the magnification rate is effective for creating an image that matches the perceived size of the object at the scene. Our results indicate that the magnification rate is useful for transforming the perspective image to match our perception of the objects regardless of the viewing distance.     

Imitative learning from a third-party interaction: relations with self-recognition and perspective taking

Young children’s ability to learn something new from a third-party interaction may be related to the ability to imagine themselves in the third-party interaction. This imaginative ability presupposes an understanding of self-other equivalence, which is manifested in an objective understanding of the self and an understanding of others’ subjective perspectives. The current study measured imitative learning of a novel action seen only in a third-party interaction, mirror self-recognition, and perspective taking in a group of 48 18- to 20-month-olds. Patterns of performance suggest that understanding self-other equivalence is related to third-party learning.
