Career As Life-Style: An Existential View

Many individuals in our society experience degrees of psychological and spiritual deadness. This early-death syndrome is contrasted with a view of life that encompasses the concept of an ongoing prime through growth in psychological and spiritual aliveness. A four-dimensional model of career is presented that incorporates existential concepts and advocates attention to both experiences and personal philosophy as factors in the attainment of a meaningful life-style.     

Correcting Differences in Answer Sheets for the 1980 Armed Services Vocational Aptitude Battery Reference Population

In the late 1970s, the Department of Defense (DoD) requested that the reference population for the Armed Services Vocational Aptitude Battery (ASVAB), at that time based on a 1944 sample, be changed and updated to reflect the current youth population. In 1980, the data for the new reference group were collected. Data analyses indicate that the new sample's speeded test scores are atypically low; therefore, the sample might be inappropriate as a reference. The problem was traced to the format of an answer sheet used in the 1980 youth population data collection. In our study, we tested the differences between performance on the 1980 youth study answer sheet and that used operationally for the ASVAB. An adjustment was developed to resolve those differences. Data for this study were scores on two ASVAB speeded tests of about 9,500 service applicants at Military Entrance Processing Stations (MEPS). Half of these applicants were tested on the operational ASVAB answer sheet; half were tested with the answer sheet used in the 1980 youth study. The speeded test scores derived from the 1980 youth study answer sheets were then equated to those derived from the operational ASVAB answer sheets. Adjustments based on these equatings resolved the speeded test anomalies observed in the 1980 youth study.     

The Conceptualization of Team Flow

Despite the noted potential for team flow to enhance a team's effectiveness, productivity, performance, and capabilities, studies on the construct in the workplace context are scarce. Most research on flow at the group level has been focused on performance in athletics or the arts, and looks at the collective experience. But, the context of work has different parameters, which necessitate a look at individual and team level experiences. In this review, we extend current theories and essay a testable, multilevel model of team flow in the workplace that includes its likely prerequisites, characteristics, and benefits.     

Flow: Beyond Fluidity and Rigidity

The term flow refers to a particular type of experience characterized by feelings of fusion with an on-going activity, effortlessness and fluidity. This article concerns the results of an empirical investigation and phenomenological analysis of this type of experience. The analysis yields a distinction between three phenomenological structures, identified as arising in different combinations within concrete experiences of flow. These results are discussed in relation to the theories of Alfred Schutz and Erving Goffman regarding the organization of experience in everyday life, and in relation to the theory of Otto Friedrich Bollnow regarding moods in everyday life. The results of the analysis are also discussed in relation to different uses of the flow concept in a variety of contexts found in recent theoretical contributions. These differences of usage and approach are explained in the light of the results of the phenomenological analysis, which distinguishes qualitatively different varients within the phenomenon termed flow experience. In conclusion, the need to adopt a broader concept of experience in sociological analysis is emphasized, as well as the need for further empirical studies of the contextual frames of different variants of flow experiences.     

Flow experience influenced by car adjustments

Today’s cars offer a variety of possible setting options which have to be chosen by the driver. In order to examine the psychological effect of automatic adjustments in comparison to manual adjustments of the chassis and drive train while driving, a test vehicle was built up and tested in a naturalistic field operation test (nFOT) through various development stages. 207 BMW employees participated in the study focusing on emotional feedback and flow experience. The results were used to improve the function and to start the test scenario again.The automatic adjustment of the car’s setting (driving mode) due to the detection of the intended driving style of the subjects was preferred to the manual adjustments. Additionally, the feeling of safety increased while the level of distraction decreased. Our findings show that in addition to the positive technical aspects of an automatic adjustment, there is also an increase in driving experience, measured by the flow experience and the feeling of safety.     

Flow研究概述

Flow是一种重要的积极情绪,它是指人们对某一活动或事物表现出浓厚的兴趣并推动个体完全投入某项活动或事物的一种情绪体验。Flow体验具有九个特征,即所感知到的活动挑战性与技能水平相平衡、行动与意识相融合、明确的活动目的、清晰的即刻反馈、对当前活动的高度投入、控制感、丧失自我意识、活动的内在奖励以及时间体验失真。心理学界的Flow研究已主要在Flow自身属性和应用两个领域展开,而对Flow的测量主要有面谈、问卷调查和ESM等三种方法     

Flow and Happiness in Later Life: An Investigation into the Role of Daily and Weekly Flow Experiences

Fifty-four older adults ranging in age from 70 to 86 years old (M = 77.54) reported daily levels of positive and negative affect, life satisfaction and daily activities for seven consecutive days. Hierarchical linear modeling (HLM) was used to investigate inter- and intra-individual effects of flow experiences on affect. Higher quality of flow was positively associated with high arousal positive affect (i.e., feeling peppy, enthusiastic, happy), negatively associated with low arousal negative affect (i.e., feeling sad and disappointed), and positively associated with life satisfaction. However, more frequent flow experiences throughout the week predicted lower average levels of positive affect and life satisfaction. Overall, the results demonstrate that flow is linked to the affective experiences of older adults, and that an individual’s overall propensity to experience flow may be influential beyond the immediate effects of a given flow experience.     

Dynamics of Flow: A Nonlinear Perspective

The aims of this study are to consider the experience of flow from a nonlinear dynamics perspective. The processes and temporal nature of intrinsic motivation and flow, would suggest that flow experiences fluctuate over time in a dynamical fashion. Thus it can be argued that the potential for chaos is strong. The sample was composed of 20 employees (both full and part time) recruited from a number of different organizations and work backgrounds. The Experience Sampling Method (ESM) was used for data collection. Once obtained the temporal series, they were subjected to various analyses proper to the complexity theory (Visual Recurrence Analysis and Surrogate Data Analysis). Results showed that in 80% of the cases, flow presented a chaotic dynamic, in that, flow experiences delineated a complex dynamic whose patterns of change were not easy to predict. Implications of the study, its limitations and future research are discussed.

The Flow State Scale-2 and Dispositional Flow Scale-2: Examination of factorial validity and reliability for Japanese adults

ObjectiveThe primary purpose of this study was to examine the factorial validity and reliability of the Japanese versions of the Flow State Scale-2 and Dispositional Flow Scale-2 (JFSS-2 and JDFS-2) for use with Japanese adults.MethodTo accomplish the aim, a multi-staged approach was employed. Following the guidelines for test adaptation [Tanzer, N. K., & Sim, C. Q. E. (1999). Adapting instruments for use in multiple languages and cultures: A review of the ITC guidelines for test adaptations. European Journal of Psychological Assessment, 15, 258–269], the two flow scales were translated from English to Japanese and the best 36 items for each instrument was identified through two pilot studies. Employing a 9-factor 1st-order hypothesized model, the factorial validity of the JFSS-2 and JDFS-2 was tested and cross-validated with confirmatory factor analysis (CFA). In addition to internal consistency reliability for the both scales, stability was assessed over a 4-week time period for the JDFS-2. Furthermore, measurement equivalence was examined across Japanese independent samples as well as two cultural samples.ResultsThe results of a series of CFAs revealed that the data for the JFSS-2 and JDFS-2 were represented appropriately by the hypothesized 1st-order model. For the both scales, internal consistency estimates for all factors were satisfactory, whereas the stability of single factors over time were medium to high. Measurement invariance was established across the Japanese samples as well as the cultural samples.ConclusionsThe findings from this study provided strong support for the validity and reliability of the JFSS-2 and JDFS-2 in assessing flow experiences in physical activity for Japanese adults. In addition, this study indicated that the Japanese versions of the flow scales are useful instruments for cross-cultural research.     

Flow,performance and moderators of challenge-skill balance

The concept of flow is briefly reviewed and several theoretical and methodological problems related to flow research are discussed. In three studies, we attempted to avoid these problems by measuring the experience of flow in its components, rather than operationally defining flow in terms of challenge and skill. With this measure, we tested the assumption that experience of flow substantially depends on the balance of challenge and skill. This assumption could only be partially supported, and, as expected, this relationship was moderated by the (perceived) importance of the activity and by the achievement motive. Furthermore, flow predicted performance in two of the three studies.

Flow experience among information and communication technology users

The use of technologies is more common in daily life; working with technologies might be associated with positive experiences such as flow. However, there is little empirical research on flow experiences in technology settings. The main aim of this study was to confirm the three-dimensional construct of flow, i.e., absorption, enjoyment, and intrinsic interest, among 517 Information and Communication Technology users [234 students whose mean age was 23 yr. (SD = 3.8)] from different areas of study, mainly Law, Public Administration, Chemistry, and Psychology, and 283 employees [whose mean age was 33 yr. (SD = 7.8)] of 21 different companies from various sectors of production, namely, public administration, industrial production, and services. Analysis showed, as expected, flow is a three-dimensional psychological construct and invariant among samples of technology users. Practical and theoretical implications as well as further research are discussed.     

Determinism, Indeterminism And The Flow Of Time

A set of axioms implicitly defining the standard, though not instant-based but interval-based, time topology is used as a basis to build a temporal modal logic of events. The whole apparatus contains neither past, present, and future operators nor indexicals, but only B-series relations and modal operators interpreted in the standard way. Determinism and indeterminism are then introduced into the logic of events via corresponding axioms. It is shown that, if determinism and indeterminism are understood in accordance with their core meaning, the way in which they are formally introduced here represents the only right way to do this, given that we restrict ourselves to one real world and make no use of the many real worlds assumption. But then the result is that the very truth conditions for sentences about indeterministic events imply the existence of tensed truths, in spite of the fact that these conditions are formulated (in the indeterministic axiom) in terms of tenseless language. The tenseless theory of time implies determinism, while indeterminism requires the flow of time assumption.
