Thanatoperience

Near-death experiences (NDEs) can be seen as special cases of psychological transition. They often involve a deep transformation in the sense of self. I examine the NDE as such, according to my phase theory of transition, and I analyze an NDE with the help of that theory. I conclude that the study of NDEs may provide insight into the general psychology of transition.     

Problem‐Solving Phase Transitions During Team Collaboration

Multiple theories of problem‐solving hypothesize that there are distinct qualitative phases exhibited during effective problem‐solving. However, limited research has attempted to identify when transitions between phases occur. We integrate theory on collaborative problem‐solving (CPS) with dynamical systems theory suggesting that when a system is undergoing a phase transition it should exhibit a peak in entropy and that entropy levels should also relate to team performance. Communications from 40 teams that collaborated on a complex problem were coded for occurrence of problem‐solving processes. We applied a sliding window entropy technique to each team's communications and specified criteria for (a) identifying data points that qualify as peaks and (b) determining which peaks were robust. We used multilevel modeling, and provide a qualitative example, to evaluate whether phases exhibit distinct distributions of communication processes. We also tested whether there was a relationship between entropy values at transition points and CPS performance. We found that a proportion of entropy peaks was robust and that the relative occurrence of communication codes varied significantly across phases. Peaks in entropy thus corresponded to qualitative shifts in teams’ CPS communications, providing empirical evidence that teams exhibit phase transitions during CPS. Also, lower average levels of entropy at the phase transition points predicted better CPS performance. We specify future directions to improve understanding of phase transitions during CPS, and collaborative cognition, more broadly.     

Pressure-induced changes in electronic and vibrational properties of LaS

The high-pressure induced phase transition in LaS has been investigated by means of first-principles calculations, and density-functional linear-response theory. A pressure-induced soft-acoustic phonon mode is identified at 30?GPa, which is in favourable agreement with the measured pressure-induced phase transition in LaS from the rocksalt to the CsCl structure. Phonon calculations reveal that pressure-induced instabilities of the transverse acoustic modes at the [?00] and [??0] directions are responsible for the phase transition. Furthermore, it is found that a decrease of bonding for S-p bonds and an increase of anti-bonding for La-d bonds significantly weakens the stability of the rocksalt phase of LaS under pressure, and hence inducing the structural phase transformation.

As the Lights Fade: A Grounded Theory of Male Professional Athletes’ Decision-Making and Transition to Retirement

Retirement can be particularly challenging for professional athletes, given their commitment and identification with their sport. The purpose of this study was to examine how American male professional athletes make the decision to retire and how that decision process affects transition in retirement. The researchers used constructivist grounded theory to analyze personal accounts from professional athletes who wrote about retirement, and a model on the decision-making and transition process of retirement was developed. The findings show that athletes struggle in retirement, but by relying on their social support, they can accept the conclusion of their career as a professional athlete.     

Autobiographical Misremembering: John Dean is not Alone

Survey respondents were asked to provide knowledge responses to public events and names that occurred as long ago as the 1930s and as recently as the 1980s. Respondents made errors that reflect the use of semantic and lexical memory systems, and reconstructive processes based on a semantic theme. Errors, as well as correct responses, are affected by whether the events originally occurred during the transition phase (early teens to mid-twenties). Responses indicate that events that occur during the transition phase are remembered better than events that occur during other life phases (in contradiction to the differential sampling hypothesis), but that events that occur during the transition phase can also promote error-prone reporting by interfering with other events or by promoting inaccurate reconstructions. The evidence suggests that the transition phase is not a monolithic entity, but that young adolescence differs from older transition phase ages by having a greater concentration on determining general properties of the world. Support is strongest for cognitive accounts of transition phase effects such as the first experience hypothesis, and results challenge physiological and evolutionary accounts that are tied to the transition phase promoting better memory. Finally, the more dramatic observed errors (such as inverting the subject and object of an event) point to possible undocumented instances of autobiographical misremembering. © 1997 by John Wiley & Sons, Ltd.     

On the girl's psychosexual development: reconsiderations suggested from direct observation

Following on two decades of longitudinal direct observation of young children, revisions of two component parts of psychosexual theory seem warranted. First, direct observation does not support the concept of a "phallic" phase as being representative of the girl's first genital phase. Observational findings challenge "phallic" concept-dependent hypotheses Freud proposed in 1925, including how the girl enters her Oedipus complex as well as the nature of her wish to have a baby. In the children observed by the author, phallic aggression was not manifest as much in girls as in boys, between the ages of two and four. Second, it is proposed we put aside the "phallic" phase concept in our considerations of the girl's dynamics and that we heighten our awareness of her early experiences of ambivalence--which lie at the heart of the oedipal conflict--and which leads to a formulation of superego development in the girl more compatible with clinical findings.     

Retirement Adjustment Quality: Optimism and Self-Efficacy as Antecedents of Resource Accumulation

The resource-based dynamic perspective posits that retirement adjustment quality is a direct result of an individual’s access to valuable resources during transition and in the post-retirement phase, while at the same time underscoring the need to explore the distal antecedents of adjustment quality. The present study aims to examine how distal antecedents—dispositional traits and motivational variables—influence older workers’ resource accumulation and, ultimately, how it affects retirement adjustment quality, under the resource-based dynamic perspective and Hobfoll’s resource theory. A three-wave study was designed with older Spanish workers (N = 455), who were still in active employment at time 1 and time 2 but who had retired within the last 4 months at time 3. Dispositional traits like optimism have predictive power as a gauge of resource accumulation in the short run, although not all of them were fully significant. Some unexpected findings are the limited impact of personal finances on retirement adjustment quality and the absolutely nugatory influence of cognitive resources on quality of life. The present study employs a widely validated measure of retirement adjustment quality, which should ensure comparability of findings with evidence obtained from other studies.     

Metacognition in monkeys during an oculomotor task

This study investigated whether rhesus monkeys show evidence of metacognition in a reduced, visual oculomotor task that is particularly suitable for use in fMRI and electrophysiology. The 2-stage task involved punctate visual stimulation and saccadic eye movement responses. In each trial, monkeys made a decision and then made a bet. To earn maximum reward, they had to monitor their decision and use that information to bet advantageously. Two monkeys learned to base their bets on their decisions within a few weeks. We implemented an operational definition of metacognitive behavior that relied on trial-by-trial analyses and signal detection theory. Both monkeys exhibited metacognition according to these quantitative criteria. Neither external visual cues nor potential reaction time cues explained the betting behavior; the animals seemed to rely exclusively on internal traces of their decisions. We documented the learning process of one monkey. During a 10-session transition phase, betting switched from random to a decision-based strategy. The results reinforce previous findings of metacognitive ability in monkeys and may facilitate the neurophysiological investigation of metacognitive functions.     

Phase transitions and critical fluctuations in the visual coordination of rhythmic movements between people

By watching each other's lower oscillating leg, 2 seated Ss kept a common tempo and a particular phase relation of either 0 degrees (symmetric mode) or 180 degrees (alternate mode). This study investigated the differential stability of the 2 phase modes. In Experiment 1, in which Ss were instructed to remain in the initial phase mode, the alternate phase mode was found to be less stable as the frequency of oscillation increased. In addition, analysis of the nonsteady state cycles revealed evidence of a switching to the symmetric phase mode for the initial alternate phase mode trials. In Experiments 2 and 3, Ss were instructed to remain at a noninitial phase angle if it was found to be more comfortable. The transition observed between the 2 phase modes satisfies the criteria of a physical bifurcation--hysteresis, critical fluctuations, and divergence--and is consonant with previous findings on transitions in limb coordination within a person.     

Older Workers and Bridge Employment: Redefining Retirement

The authors present a qualitative study that explored the transition experiences of older workers who retired from long‐term careers and who were working in bridge jobs (i.e., transitional work between career employment and retirement). Using grounded theory methodology, the authors interviewed 24 older workers to learn why they decided to pursue a bridge job, how they made the transition, and what challenges they faced and benefits they received. The core theme from the study is that bridge employment redefines retirement. The authors present the findings of the study along with recommendations for career counselors and implications for future research.     

Systemic Barriers to Family Involvement in Transition Planning for Youth with Disabilities: A Qualitative Metasynthesis

Family involvement is particularly important to the postschool success of young adults with disabilities who typically experience fewer education and employment opportunities after leaving high school than their same age peers without disabilities. Despite mandates for family involvement, school-home partnerships remain elusive, particularly for low-income and culturally and linguistically diverse families. This metasynthesis of findings from 22 qualitative studies examines family perceptions of barriers to transition from school to adulthood and involvement in transition planning. This metasynthesis adds to the literature on family involvement in special education by utilizing Bourdeuian social reproduction theory and Bronfenbrenner's ecological systems theory to frame the discussion and inform recommendations for research and practice that focus on schools and adult service systems rather than deficiencies in families.     

Ego Development during the Transition from Adolescence to Young Adulthood: A 9-Year Longitudinal Study

Although Loevinger's (1976) ego development theory represents a milestone approach to life-span personality development, little is known about ego development during the transition from adolescence to young adulthood, including the average gain in group means, whether individuals maintain their relative position to each other, and age-related changes in within-cohort variability. These issues are examined using the ongoing Block and Block Longitudinal Study. Across a 9-year interval—from age 14 to age 23—the findings indicate that: (a) the average person gains approximately 1.5 ego development steps, (b) within-cohort variability in ego development increases with age, (c) ego level at ages 14 and 23 is moderately related, (d) large individual differences exist in the timing and extent of ego development, and (e) the magnitude of change is smallest for individuals who have already reached the Self-aware level as adolescents. The findings suggest that the Self-aware level represents a developmental “hurdle” during the transition from adolescence to young adulthood. Possible explanations are explored in terms of pacers for ego development.     

生育年龄限制感提高女性的计划生育数量

近几年我国已陷入低生育率国家的行列, 提高育龄女性的生育意愿迫在眉睫。本研究结合心理阻抗以及毕生控制理论, 探索女性对于生育的年龄限制的知觉对于其生育意愿和计划生育数量的影响。研究1为问卷研究, 结果显示, 女性距离自己认为的理想生育年龄越接近时, 生育意愿越强烈。研究2和研究3为实验法研究, 分别启动未婚女性(研究2)和已婚女性(研究3)对于女性生育年龄的限制感。结果表明, 生育年龄的时间限制可以提升未婚女性对儿童的内隐态度和已婚女性的计划生育数量。研究2还发现, 这种提升效果对于前测生育意愿高的女性影响更大, 且将最佳生育年龄设定为26岁的提升效果优于设定为32岁。本研究的结果表明, 生育限制感可以提高女性的生育意愿。创设女性对适宜生育的年龄有限制感的环境, 将有助于提升育龄女性的生育意愿。不建议以进一步放开人口生育指标(如全面放开生育数量的限制)作为提高生育率的手段, 这反而可能导致育龄女性的生育意愿进一步下滑。     

Profiling retirees in the retirement transition and adjustment process: examining the longitudinal change patterns of retirees' psychological well-being

The author used role theory, continuity theory, and the life course perspective to form hypotheses regarding the different retirement transition and adjustment patterns and how different individual and contextual variables related to those patterns. The longitudinal data of 2 samples (n(1) = 994; n(2) = 1,066) from the Health and Retirement Survey were used. Three latent growth curve patterns of retirees' psychological well-being were identified as coexisting in the retiree samples through growth mixture modeling (GMM) analysis. On the basis of the latent class membership derived from GMM, retiree subgroups directly linked to different growth curve patterns were profiled with individual (e.g., bridge job status) and contextual variables (e.g., spouse working status). By recognizing the existence of multiple retiree subgroups corresponding to different psychological well-being change patterns, this study suggests that retirees do not follow a uniform adjustment pattern during the retirement process, which reconciles inconsistent previous findings. A resource perspective is further introduced to provide a more integrated theory for the current findings. The practical implications of this study are also discussed at both individual level and policy level.     

From Piaget's Epistemic Subject to Pascual-Leone's Metasubject: Epistemic Transition in the Constructivist—Rationalist Theory of Cognitive Development

The explanation of the transition from one epistemic theory to another is an important part of Piaget's genetic epistemology. It is argued that this epistemic transition leads to a retrodictable orthogenetic tendency toward optimizing equilibration. The objective of this paper is to establish a relationship between Piaget's epistemic subject and Pascual-Leone's metasubject and to demonstrate that the postulation of the latter can be considered as an epistemic transition between two constructivist—rationalist theories, which leads to the development of a theory with greater explanatory power. Epistemic transition in this paper refers to a progressive problemshift (cf. Lakatos, 1970), between the theories of Piaget and Pascual-Leone. Piaget builds a “general model” by neglecting individual differences, that is, studies the epistemic subject, whereas Pascual-Leone by incorporating a framework for individual difference variables, studies the metasubject—the psychological organization of the epistemic subject. Empirical evidence is presented to demonstrate that Pascual-Leone's theory of constructive operators is a model of the psychological organism (the metasubject), which is at work inside Piaget's epistemic subject. Finally, it is concluded that the greater explanatory power of Pascual-Leone's theory can be interpreted as an epistemic transition between Piaget's epistemic subject and Pascual-Leone's metasubject.     

Stressful work, psychological job strain, and turnover: a 2-year prospective cohort study of truck drivers

Based on a model that combines existing organizational stress theory and job transition theory, this 2-year longitudinal study examined antecedents and consequences of turnover among Dutch truck drivers. For this purpose, self-reported data on stressful work (job demands and control), psychological strain (need for recovery after work and fatigue), and turnover were obtained from 820 drivers in 1998 and 2000. In agreement with the model, the results showed that strain mediates the influence of stressful work on voluntary turnover. Also in conformity with the model, job movement to any job outside the trucking industry (i.e., interoccupational turnover) resulted in a larger strain reduction as compared to job movement within the trucking industry (intraoccupational turnover). Finally, strain was found to stimulate interoccupational turnover more strongly than it stimulated intraoccupational turnover. These findings provide a thorough validation of existing turnover theory and give new insights into the turnover (decision) process.     

Aspects of the syntax of behavior: Syllable structure and speech rate

This paper shows that maximal rate of speech varies as a function of syllable structure. For example, CCV syllables such as [sku] and CVC syllables such as [kus] are produced faster than VCC syllables such as [usk] when subjects repeat these syllables as fast as possible. Spectrographic analyses indicated that this difference in syllable duration was not confined to any one portion of the syllables: the vowel, the consonants and even the interval between syllable repetitions was longer for VCC syllables than for CVC and CCV syllables. These and other findings could not be explained in terms of word frequency, transition frequency of adjacent phonemes, or coarticulation between segments. Moreover, number of phonemes was a poor predictor of maximal rate for a wide variety of syllable structures, since VCC structures such as [ulk] were produced slower than phonemically longer CCCV structures such as [sklu], and V structures such as [a] were produced no faster than phonemically longer CV structures such as [ga]. These findings could not be explained by traditional models of speech production or articulatory difficulty but supported a complexity metric derived from a recently proposed theory of the serial production of syllables. This theory was also shown to be consistent with the special status of CV syllables suggested by Jakobson as well as certain aspects of speech errors, tongue-twisters and word games such as Double Dutch.
