Sex Roles in Management: The Impact of Varying Power of Speech Style on Union Members' Perception of Satisfaction and Effectiveness

Effective management has traditionally been associated with men and masculine characteristics. In this study, I focused on manager communication, specifically the perceived effects of stereotypical gender/power speech styles. Union members viewed and rated a male and a female manager on videotape using three gender/power speech styles: stereotypical masculine (powerful), stereotypical feminine (powerless), and mixed gender/power. Union respondents judged both the male and female manager using the mixed gender/power speech style as most effective and as being associated with the most satisfied employees.     

The Relationships Among Black Consciousness,Self-Esteem,and Academic Self-Efficacy in African American Men

The purpose of this study was to investigate the relationships among Black consciousness, self-esteem, and academic self-efficacy in African American men. The participants were 120 African American male college students at a predominantly African American university. The authors administered 3 instruments—the Developmental Inventory of Black Consciousness (DIB-C; J. Milliones, 1980), the M. Rosenberg (1965) Self-Esteem Scale, and R. E. Wood and E. A. Locke's (1987) Academic Self-Efficacy Scale—to test the hypotheses. They used an independent-measures t test and a Pearson r correlation to analyze the data. The results of the study supported the hypotheses under investigation. Significant positive relationships were found between Black consciousness and self-esteem and Black consciousness and academic self-efficacy. The results of the study showed that Black consciousness appears to be an important construct to use in understanding self-esteem and academic self-efficacy in African American men.     

The case of the magic bones: Dogs’ memory of the physical properties of objects

Dogs’ memory for properties of occluded objects was assessed using a looking-time procedure. The looking-time procedure has been used to indicate that a change in expectation has been observed, with longer looking times associated with change as compared with no change. In our experiments, a bone-shaped dog biscuit (bone) was placed behind a horizontal screen that then rotated up to occlude the object before the screen returned to its horizontal position. Dogs were shown one of two test events. In one (congruent) event, the screen rotated up to obscure the bone and then rotated back down to reveal the unchanged bone. In the other (incongruent) event, the screen rotated up to obscure the bone and then rotated back down to reveal a bone that had changed in size (Experiment 1) or color (Experiment 2). Looking times were measured to assess which events represented the detection of a change. Increased looking time on incongruent trials indicated that the dogs remembered the size and color of the occluded object.     

Memory abilities in generally gifted and excelling-in-mathematics adolescents

This paper presents part of a multidimensional examination of mathematical giftedness. The present study examined the memory mechanisms associated with general giftedness (G) and excellence in mathematics (E) in four groups of 10th–12th grade students (16–18 years old) varying in levels of G and E. The participants first underwent the Raven test for general ability evaluation and SAT-M — the mathematical excellence tests in order to design the study groups. Afterwards, the students were tested on a battery of three memory tests including tests for short-term (STM) and working memory (WM). The results reveal that the G factor is related to high STM for both phonological loop and phonological central executive mechanisms. It was also found that the E factor is associated with high visual–spatial memory (VSM), in particular with the visual central executive mechanism. An interaction effect was found between G and E factors regarding WM. The central executive mechanism appeared to be related to both G and E factors. In addition, gender differences were shown within the groups. Male participants performed better than their female counterparts on a phonological storage task and a phonological central executive mechanism task. The results can contribute to the theoretical knowledge regarding similarities and differences in memory mechanisms in G and E groups.     

社会自我效能感的结构、测量及其作用机制

班杜拉的自我效能理论一直是当代心理学的热点话题。作为社交情境中的特殊自我效能感,社会自我效能感是能够影响个人人际互动质量的重要心理因素之一,因此也逐渐开始受到研究者的关注。通过对国内外理论文章与实证研究的分析发现,社会自我效能感与社交自尊、社交果敢性、社交信心等相关概念有所不同,是指个体对自己社交能力的主观信念;其内涵在不同文化自我或情境的视角下可能存在差异,具有多元结构的可能性。社会自我效能感与个人特质、情绪、态度及行为等变量相关,并能够显著预测抑郁、社交焦虑、生活满意度、社会适应等变量。此外,社会自我效能感也在外向、性别角色、依恋、目标定向、网络人际交往的影响机制中起到中介作用,且能够对压力和不公平感所造成的消极影响具有一定的缓冲作用。然而有关研究仍存在诸多问题与不足,未来研究应该关注社会自我效能感内涵与结构的确定、测量工具的开发,并加强对其影响因素与影响效应的探索、系统模型的构建和跨文化研究的扩展。     

The effects of collaborative practice on statistical problem solving: Benefits and boundaries

In recent years, understanding the effects of collaboration on learning and memory has emerged as a major topic of investigation. Findings from applied educational research and from basic cognitive research demonstrate a complex view of how collaboration affects learning. The present laboratory study bridged these two domains of research to address the question of how collaborative learning affects statistical problem solving. After viewing a lecture, participants completed two statistics tests. They either completed the tests collaboratively and then individually, or completed both tests individually. Results showed an immediate benefit of collaboration, but this benefit did not persist on a subsequent individual test. Repeated practice by those who worked individually increased performance to the level of those who had previously collaborated. These results were qualified by gender as females showed a consistent benefit from prior collaboration on the post-collaborative test, particularly on conceptual problems. Implications for education are discussed.     

Subjective cognitive complaint in healthy older adults: Identification of major domains and relation to objective performance

This study analyzed complaints across a range of memory domains in middle-aged and older adults, as well as assessed their relationship with objective cognitive performance and personal characteristics. A total of 115 community-dwelling, healthy adults between the ages of 45 and 87 completed the Self-Evaluation Questionnaire (QAM) and were tested with a comprehensive neuropsychological battery. A principal component analysis identified seven dimensions of complaint. Difficulty inhibiting internal and external sources of interference when learning or remembering something was the main area of complaint and it was correlated with word-list recall and Digit Symbol. We identified complaints related to a set of memory failures that appear to be more detrimental to autonomy and safety. These were correlated with a measure of functional autonomy and might, therefore, indicate more severe difficulties. Overall, this study provides indications regarding the main domains of memory complaints and identifies which complaints are most reflective of objective cognitive problems.     

The effects of exposure to dynamic expressions of affect on 5-month-olds’ memory

The purpose of this study was to examine the behavioral effects of adults’ communicated affect on 5-month-olds’ visual recognition memory. Five-month-olds were exposed to a dynamic and bimodal happy, angry, or neutral affective (face–voice) expression while familiarized to a novel geometric image. After familiarization to the geometric image and exposure to the affective expression, 5-month-olds received either a 5-min or 1-day retention interval. Following the 5-min retention interval, infants exposed to the happy affective expressions showed a reliable preference for a novel geometric image compared to the recently familiarized image. Infants exposed to the neutral or angry affective expression failed to show a reliable preference following a 5-min delay. Following the 1-day retention interval, however, infants exposed to the neutral expression showed a reliable preference for the novel geometric image. These results are the first to demonstrate that 5-month-olds’ visual recognition memory is affected by the presentation of affective information at the time of encoding.     

Electrophysiological correlates of processes supporting memory for faces

The retrieval processes supporting recognition memory for faces were investigated using event-related potentials (ERPs). The focus for analyses was ERP old/new effects, which are the differences between neural activities associated with correct judgments to old (studied) and new (unstudied) test stimuli. In two experiments it was possible to identify three old/new effects that behaved as neural indices of the process of recollection. In both experiments there was one old/new effect that behaved as an index of the process of familiarity. These outcomes are relevant to the ongoing debate about the functional significance of ERP old/new effects and the implications that scalp-recorded electrophysiological data have for theories of the processes supporting long-term memory judgments.
