Image Organization

This is a preprint. Please find the published and peer reviewed version of the paper here: https://www.journalofcognition.org/articles/10.5334/joc.80/. Images differ in their intrinsic memorability. The factors driving image memorability are not fully understood. Here, we hypothesized that memorability at least partly depends on goodness of image organization. Good organizations have been associated with fast, efficient processing and robustness against transformation (e.g., shrinking). Based on the main hypothesis, these characteristics would then also pertain to memorable images. Study 1 focused on fast processing and predicted that memorable images are easier to categorize rapidly, while Study 2 predicted that they survive a shrinking transformation better. We used real-life scene images of 14 semantic categories from a previous memorability study. Each image was assigned a “categorizability” and “shrinkability” score based on the average performance across participants on a rapid-scene categorization task (Study 1) and a thumbnail search task (Study 2), respectively. The predicted positive relation between categorizability and memorability was not observed. A post-hoc explanation attributed this null result to a masking role of image distinctiveness. In the thumbnail search task, memorable images were located faster, as predicted, but Study 2 could not rule out that this was merely a result of their distinctiveness. A third study quantified the images on distinctiveness and statistically controlled for this variable in a reanalysis of Study 1 and Study 2. When distinctiveness was controlled for, categorizability and memorability did show a significant positive correlation. Moreover, the results also argued against the alternative explanation of the results of Study 2. Taken together, the results support the hypothesis that goodness of organization contributes to image memorability.

AbstractThis study examines the relations among style and development level of four interpersonal and intrapsychic processes: interpersonal thought, self-reported interpersonal action, mechanisms of defense, and object representation. Subjects were 25 girls and 25 boys from the eighth grade of an urban public school System. All four constructs were measured along developmental and stylistic dimensions. Both interpersonal thought and self-reported action processes were measured with the hypothetical and real-life interpersonal negotiation strategies interviews of Selman and colleagues. Defensive process was measured with a questionnaire revised to include Vaillant's developmental analysis of defense mechanisms as well as assessment of style of defense (internalizing vs. externalizing). Object representation style and level were measured with constructs and instruments of Blatt and colleagues. The results supported the main hypothesis: Levels of defense mechanisms and object representation independently predicted level of self-reported interpersonal action, even when controlling for level of interpersonal thought (which also predicted action). This suggests that if there are gaps between interpersonal thought and action levels, the relative level of maturity of psychodynamic processes helps explain action level. In contrast, there were few relationships among the stylistic components of the four constructs, although each style construct was related to its associated level construct. Contrary to hypotheses, no gender differences were found on any of the composited level or style variables. The study suggests operational links between structural-developmental and psychodynamic aspects of personality.

The present study compared cognitive abilities and academic achievement of adolescents studying in three different school systems namely Urdu medium schools, English medium schools, and Cambridge system schools. The sample comprised of 1001 secondary school student. Cognitive abilities were assessed by Raven’s Standard Progressive Matrices (1960) and marks obtained by the students in the last annual examination were used as an index of academic achievement. Results showed that cognitive abilities of the students were positively associated with academic achievement of the respondents. It was further found that cognitive abilities and academic achievement of students studying in Cambridge school system was better as compared to those studying in other systems. Post-hoc comparison revealed that level of academic achievement of Urdu medium schools was lower as compared to English medium and Cambridge system of schools. The findings suggest that difference in schooling system influenced cognitive abilities and academic achievement of the students. Results further demonstrated that gender was a significant predictor of academic achievement in both Urdu and English medium schools. Future implications of the study were also discussed.

In the anarchism that governs the nature and patterns of international relations characterized by instability and uncertainty in light of several changes, as well as the information revolution and the resulting developments and qualitative breakthroughs in the field of scientific and advanced technological knowledge and modern technologies.  All of these variables pushed toward the information flow and flow tremendously, so rationality became an indispensable matter for the decision maker as he faces these developments and changes. There must be awareness and rationality in any activity or behavior because it includes choosing the best alternative and making the right decision and selecting the information accurately and mental processing Through a mental system based on objectivity, methodology, and accumulated experience away from idealism and imagination, where irrationality and anarchy are a reflection of the fragility of the decision-maker, his lack of awareness of the subject matter, his irresponsibility, and recklessness that inevitably leads to failure by wasting time and Effort and potential. The topic acquires its importance from a search in the strategies of the frivolous state and its characteristics with the ability to influence the regional, and what it revealed is a turning point in how to adapt from the variables and employ them to their advantage and try to prove their existence. Thus, the problem comes in the form of a question about the possibility of the frivolous state in light of the context of various regional and international events and trends. The answer to this question stems from the main hypothesis that (the aim which the frustrating state seeks to prove is that it finds itself compelled to choose several strategies that start from the nature of its characteristics and the goals that aim at it, which are centered in the circle of its interests in the field of its struggle for the sake of its survival and area of influence).

The CreditRisk+ model is one of the industry standards for the valuation of default risk in credit loans portfolios. The calibration of CreditRisk+ requires, inter alia, the specification of the parameters describing the structure of dependence among default events. This work addresses the calibration of these parameters. In particular, we study the dependence of the calibration procedure on the sampling period of the default rate time series, that might be different from the time horizon onto which the model is used for forecasting, as it is often the case in real life applications. The case of autocorrelated time series and the role of the statistical error as a function of the time series period are also discussed. The findings of the proposed calibration technique are illustrated with the support of an application to real data.

AbstractIn the absence of any neuropsychiatric condition, older adults may show declining performance in several cognitive processes and among them, in retrieving and producing words, reflected in slower responses and even reduced accuracy compared to younger adults. To overcome this difficulty, healthy older adults implement compensatory strategies, which are the focus of this paper. We provide a review of mainstream findings on deficient mechanisms and possible neurocognitive strategies used by older adults to overcome the deleterious effects of age on lexical production. Moreover, we present findings on genetic and lifestyle factors that might either be protective or risk factors of cognitive impairment in advanced age. We propose that “aging-modulating factors” (AMF) can be modified, offering prevention opportunities against aging effects. Based on our review and this proposition, we introduce an integrative neurocognitive model of mechanisms and compensatory strategies for lexical production in older adults (entitled Lexical Access and Retrieval in Aging, LARA). The main hypothesis defended in LARA is that cognitive aging evolves heterogeneously and involves complementary domain-general and domain-specific mechanisms, with substantial inter-individual variability, reflected at behavioral, cognitive, and brain levels. Furthermore, we argue that the ability to compensate for the effect of cognitive aging depends on the amount of reserve specific to each individual which is, in turn, modulated by the AMF. Our conclusion is that a variety of mechanisms and compensatory strategies coexist in the same individual to oppose the effect of age. The role of reserve is pivotal for a successful coping with age-related changes and future research should continue to explore the modulating role of AMF.

AbstractLearning is a complex phenomenon. Contemporary theories of education underline active participation of learners in their learning processes. One of the key arguments supporting this approach is the learner’s simultaneous and unconscious development of their ability of “learning to learn”. This ability belongs to the soft skills highly valued by employers today.For Mathematics Education, it means that teachers have to go beyond making calculations and memorizing formulas. We have to teach the subject in its social context. When the students start understanding the relationship between real-life problems and the role of numbers and formulas for their solutions, their learning becomes a part of their tacit knowledge. Below we explain the theoretical background of our approach and provide examples of such activities.

Artistic Training

In seventeenth-century Holland, the role of the live model in the making of art and, importantly, as a vehicle for artistic training had become a topic of contention. No other aspect of artists’ education had received more criticism than the use of real-life models. Artists ran the risk of drawing too much attention to the live model, leaving the model’s features visible in their works. These works would look too much like life itself. This essay argues that seventeenth-century theorists devised an intricate concept of style in order to keep life in an artwork at bay. To train artists was to discipline them in style.

The Relationship

Objective: This research examined whether negative and positive arousal emotions modify the relationship between experience level and cue utilization among anesthetists. Background: The capacity of a practitioner to form precise associations between clusters of features (e.g., symptoms) and events (e.g., diagnosis) and then act on them is known as cue utilization. A common assumption is that practice experience allows opportunities for cue acquisition and cue utilization. However, this relationship is often not borne out in research findings. This study investigates the role of emotional state in this relationship. Method: An online tool (EXPERTise 2.0) was used to assess practitioner cue utilization for tasks relevant to anesthesia. The experience of positive and negative arousal emotions in the previous three days was measured, and emotion clusters were generated. Experience was measured as the composite of practice years and hours of practice experience. The moderating role of emotion on the relationship between experience and cue utilization was examined. Results: Data on 125 anesthetists (36% female) were included in the analysis. The predicted interaction between arousal emotions and the experience level emerged. In particular, post hoc analyses revealed that anxiety-related emotions facilitated the likelihood of high cue utilization in less experienced practitioners. Conclusion: The findings suggest a role for emotions in cue use and suggest a functional role for normal range anxiety emotions in a simulated work-relevant task. Application: This research illustrates the importance of understanding the potentially functional effects common negative arousal emotions may have on clinical performance, particularly for those with less experience.

The ability to exert control over automatic behavior is of particular importance as it allows us to interrupt our behavior when the automatic response is no longer adequate or even dangerous. However, despite the literature that exists on the effects of practice on brain activation, little is known about the neuroanatomy involved in reestablishing executive control over previously automatized behavior. We present a visual search task that enabled participants to automatize according to defined criteria within about 3 hr of practice and then required them to reassert control without changing the stimulus set. We found widespread cortical activation early in practice. Activation in all frontal areas and in the inferior parietal lobule decreased significantly with practice. Only selected prefrontal (Brodmann's areas [BAs] 9/46/8) and parietal areas (BAs 39/40) were specifically reactivated when executive control was required, underlining the crucial role of the dorsolateral prefrontal cortex in executive control to guide our behavior.

Antecedents And Consequences

As our lives become increasingly dominated by mediated experiences, presence scholars have noted that an increasing number of these mediated experiences evoke (tele)-presence, perceptions that ignore or misconstrue the role of the medium in the experience. In this paper we explore an interesting countertrend that seems to be occurring as well. In a variety of contexts, people are experiencing not an illusion that a mediated experience is in fact nonmediated, but the illusion that a nonmediated “real” experience is mediated. Drawing on news reports and an online survey, we identify 3 categories of this “illusion of mediation”: positive (when people perceive natural beauty as mediated), negative (when people perceive a disaster, crime, or other tragedy such as the events of September 11, 2001, as mediated), and unusual (when close connections between people's “real life” activities and mediated experiences lead them to confuse the former with the latter). We label this phenomenon inverse presence and consider its place and value in a comprehensive theory of presence, its possible antecedents and consequences, and what it suggests about the nature of our lives in the 21st century.
