Recruitment of intuitive versus analytic thinking strategies affects the role of working memory in a gambling task

Previous studies found mixed results concerning the role of working memory (WM) in the gambling task (GT). Here, we aimed at reconciling inconsistencies by showing that the standard version of the task can be solved using intuitive strategies operating automatically, while more complex versions require analytic strategies drawing on executive functions. In Study 1, where good performance on the GT could be achieved using intuitive strategies, participants performed well both with and without a concurrent WM load. In Study 2, where analytical strategies were required to solve a more complex version of the GT, participants without WM load performed well, while participants with WM load performed poorly. In Study 3, where the complexity of the GT was further increased, participants in both conditions performed poorly. In addition to the standard performance measure, we used participants’ subjective expected utility, showing that it differs from the standard measure in some important aspects.     

Time estimation in Alzheimer's disease and the role of the central executive

The aim of this study was to evaluate the role of short-term memory and attention in time estimation. For this purpose we studied prospective time verbal estimation in 21 patients with Alzheimer's disease (AD), and compared their performance with that of 21 matched normal controls in two different conditions: during a digit span task and during an attentional task. Results showed that the performance of AD patients was significantly worse than that of the controls; the interaction between group and condition was significant. We suggest a role of attentional-executive functions in prospective time estimation.     

Generational Differences in Work-Related Attitudes: A Meta-analysis

Purpose

Differences among generations on a wide variety of outcomes are of increasing interest to organizations, practitioners, and researchers alike. The goal of this study was to quantitatively assess the research on generational differences in work-related attitudes and to provide guidance for future research and practice.

Design/Methodology/Approach

We conducted a meta-analysis of generational differences on three work-related criteria: job satisfaction, organizational commitment, and intent to turnover. Our review of published and unpublished research found 20 studies allowing for 18 generational pairwise comparisons across four generations (Traditionals, Baby Boomers, Generation Xers, and Millennials) on these outcomes using 19,961 total subjects.

Findings

Corrected mean differences for job satisfaction ranged from .02 to .25, for organizational commitment they ranged from ?.22 to .46, and for intent to turnover the range was ?.62 to .05. The pattern of results indicates that the relationships between generational membership and work-related outcomes are moderate to small, essentially zero in many cases.

Implications

The findings suggest that meaningful differences among generations probably do not exist on the work-related variables we examined and that the differences that appear to exist are likely attributable to factors other than generational membership. Given these results, targeted organizational interventions addressing generational differences may not be effective.

Originality/Value

This is the first known quantitative review of research on generational differences in the workplace.     

The Influence of Christian Conversion in Mapuche Traditional Medicine in Temuco, Chile: Toward a Cultural Syncretism or a form of Ideological Assimilation?

The Mapuche communities living in the urban areas of Chile have undergone radical cultural changes due to Christian conversion. This article analyzes the influence of these changes on the Mapuche ideas and practices of the traditional healers (machi) and patients in Temuco (IX Region), Chile, and the changes and adaptations in the perceptions of healing practices and rituals by the patients. The paper shows how, despite some evident challenges, the encounter with the religion of Christianity can create a process of cultural and spiritual syncretism and push traditional medicine toward an increased specialization in the therapeutic practices.     

When meaning is useless

The aim of this study is to disentangle the relative contribution of semantic and phonological representation in immediate serial recall. Indeed, short-term memory (STM) performance could be enhanced by familiarity with the phonological form of the word only or together with semantic information. Participants learned two sets of words in an unknown language: for one set they acquired both phonology and semantics, while for the other only phonology. After that, they performed two immediate serial recall tasks involving either “phonology and semantics” or “only phonology” words and one with untrained words. The analyses showed that the trained lists did not differ from each other, while they did from the untrained one. These data confirm that familiarity with the phonological form is sufficient for immediate serial recall. Therefore, we argue that semantics is not required for verbal STM, but knowledge of the phonological form is what matters.     

Do your high potentials have potential? The impact of individual differences and designation on leader success

We propose an integrated model of leadership potential, the high‐potential designation process, and leader success that is intended to clarify the theoretical and practical relationships among these concepts. Drawing on research in the areas of social judgment and cognition, cognitive abilities, personality, leadership development, and motivation and on practice‐oriented observations and writings, we propose a process model of potential, the designation of individuals as high potential, and the antecedent and moderating variables that combine to impact success. We conclude that by using this model we can understand better the individual, social, and organizational factors that impact potential and the high‐potential identification process, and help develop more successful leaders and organizations.     

School Bullying and Cyberbullying Among Boys and Girls: Roles and Overlap

The purpose of this study was to investigate gender differences in the overlap between school and cyberbullying according to the different types of involvement in such behaviors. The current study involved 2,785 Italian students, ages 11–17 recruited from 7 secondary schools, who anonymously self-reported about school and cyberbullying as victims and/or perpetrators. Based on their responses, students were classified as ‘only-bullies,’ ‘only-victims,’ ‘bully/victims,’ or ‘not involved’ in school and/or online. To explain the relationship between school and online bullying, 2 theoretical frames were tested: role continuity and role inversion. Results showed that, for girls, ‘school only-bullies’ were not overlapping with ‘cyber only-bullies,’ and ‘school only-victims’ were not overlapping with ‘cyber only-victims,’ but these categories were related for boys. ‘School bully/victims’ were significantly overlapping with ‘cyber bully/victims’ for both boys and girls. It was concluded that the role continuity approach is most appropriate to explain these 2 disturbing problems in adolescents especially for boys. Intervention efforts should especially target the bully/victims group.     

How grammar can cope with limited short-term memory: simultaneity and seriality in sign languages

It is known that in American Sign Language (ASL) span is shorter than in English, but this discrepancy has never been systematically investigated using other pairs of signed and spoken languages. This finding is at odds with results showing that short-term memory (STM) for signs has an internal organization similar to STM for words. Moreover, some methodological questions remain open. Thus, we measured span of deaf and matched hearing participants for Italian Sign Language (LIS) and Italian, respectively, controlling for all the possible variables that might be responsible for the discrepancy: yet, a difference in span between deaf signers and hearing speakers was found. However, the advantage of hearing subjects was removed in a visuo-spatial STM task. We attribute the source of the lower span to the internal structure of signs: indeed, unlike English (or Italian) words, signs contain both simultaneous and sequential components. Nonetheless, sign languages are fully-fledged grammatical systems, probably because the overall architecture of the grammar of signed languages reduces the STM load. Our hypothesis is that the faculty of language is dependent on STM, being however flexible enough to develop even in a relatively hostile environment.     

Suicide Signs on the Rorschach

This paper reviews the literature concerning the assessment of suicide using the Rorschach and updates the important developments since Goldfried, Stricker, and Weiner's comprehensive review of the literature in 1971. Special attention is given to those indicators which show the most support in the literature and are most efficient to use. The presence or absence of any of these signs in a patient's record should not be taken to signify the presence or absence of suicidal ideation. However, the presence of even one of these indicators does provide a warning to the clinician, indicating that further exploration in this area may be warranted. Knowledge of the many suicidal indicators on projective tests places the clinician in a better position to predict such destructive behavior and intervene appropriately.     

Esteem,Social Norms and Status Inequality

When we appraise others as talented or virtuous, we esteem them: we register admiration of their traits and virtues. It is generally believed that, unless they involve a violation of respect, distributions of esteem are not a concern from the point of view of justice. In this paper, I want to dispute this commonly-held view. I will argue that attributions of esteem can become problematic when a particular trait becomes such a uniquely relevant source of social esteem in a community that its absence becomes a reason to regard others as less than full members of the community. For instance, in contemporary capitalist societies those perceived as lacking certain socially valued traits and unable or unwilling to make certain kinds of contribution to the community, such as those who are unemployed or have committed criminal offences, are widely disesteemed and also regarded as inferior qua members of the community by others. From the fact that they fail to possess particular qualities a broader negative judgment of their ability to contribute to the community is inferred. Moreover, their failure to gain esteem in these pervasive domains eclipses their possession of other esteem-worthy traits as well as other positive contributions they might have made to society. This perception of inferiority renders it impossible for them to live on equal terms with other citizens. I argue that as egalitarians we should oppose these distributions of esteem.
