Learning and growing from ‘communities of practice’: autoethnographic narrative vignettes of an aspiring educational researcher’s experience

This is an autoethnographic study that inquiries into my own journey as an aspiring educational researcher throughout the second course of my Master’s Program at the University of Gothenburg in Sweden. My experiences take place in the context of a group of real educational researchers and their on-going research project at the faculty of education called ‘Beyond Plant Blindness: Seeing the importance of plants for a sustainable world’ (BPB). All of the experiences included in this study are expressed in the form of chronologically ordered narrative vignettes. In order to bring theoretical meaning to these experiences, the vignettes were critically reflected upon and interpreted through the concept Communities of Practice (CoP), which is central to situated learning theory. Through this conceptual lens, my experiences revealed that an aspiring educational researcher may feel emotional and intellectual growth as a newcomer who is granted legitimate peripheral participation in the ‘real’ researcher CoP. Consequently, this study sheds light on ways that real researchers may play a part in shaping the identities of aspiring educational researchers through learning experiences. However, more generally, this study may facilitate fresh conversations about the complexities of learning, identity, and inclusion in the field of educational research.     

The cognitive substrate of subjective probability

The prominent cognitive theories of probability judgment were primarily developed to explain cognitive biases rather than to account for the cognitive processes in probability judgment. In this article the authors compare 3 major theories of the processes and representations in probability judgment: the representativeness heuristic, implemented as prototype similarity, relative likelihood, or evidential support accumulation (ESAM; D. J. Koehler, C. M. White, & R. Grondin, 2003); cue-based relative frequency; and exemplar memory, implemented by probabilities from exemplars (PROBEX; P. Juslin & M. Persson, 2002). Three experiments with different task structures consistently demonstrate that exemplar memory is the best account of the data whereas the results are inconsistent with extant formulations of the representativeness heuristic and cue-based relative frequency.     

A suicide peak after weekends and holidays in patients with alcohol dependence

This paper analyzes the variation of suicide by day of the week in alcohol dependence, with public holidays taken into consideration. From 1949 through 1969, 1,312 patients with alcohol dependence were admitted to the Department of Psychiatry in Lund. By 1997, a total of 102 (99 men) alcoholic patients had taken their own life. Suicide victims with severe depression and other diagnoses were compared. There was a suicide peak on the first two days after weekends and holidays in patients with alcohol dependence (p < .05). Alcohol withdrawal is proposed as a contributor to the suicide peak.     

Individual variable pay for performance,controlling effects,and intrinsic motivation

Motivation and Emotion - A core question in research on compensation and motivation is whether individual variable pay for performance (IVPFP) can undermine intrinsic motivation in the workplace....     

Empathy and viewing the other as a subject

Empathy and viewing another person as a subject rather than an object are often associated in theoretical contexts, but empirical research of the relation is scarce. The purpose of the present research was to investigate the relationship between subject/object view and empathy. In Study 1, participants watched film clips and indicated their empathy for specific characters in the clips, as well as the extent to which they saw these persons as subjects and objects. The subject/object view explained some, but not all, of the differences in empathy, which raised the question of what else accounts for differences in empathy. A second study was conducted to investigate whether the difficulty of the other's situation also contributes. In Study 2, another group watched the film clips and rated the difficulty of the film character's situations in addition to empathy and subject/object view. The results of Study 2 revealed that subject view/object and perceived difficulty together explain a substantial part of differences in empathy. It was concluded that empathy is evoked primarily when a person in difficulty is viewed as a subject.     

Right-sided human prefrontal brain activation during acquisition of conditioned fear

This H2(15)O positron emission tomography (PET) study reports on relative regional cerebral blood flow (rCBF) alterations during fear conditioning in humans. In the PET scanner, subjects viewed a TV screen with either visual white noise or snake videotapes displayed alone, then with electric shocks, followed by final presentations of white noise and snakes. Autonomic nervous system responses confirmed fear conditioning only to snakes. To reveal neural activation during acquisition, while equating sensory stimulation, scans during snakes with shocks and white noise alone were contrasted against white noise with shocks and snakes alone. During acquisition, rCBF increased in the right medial frontal gyrus, supporting a role for the prefrontal cortex in fear conditioning to unmasked evolutionary fear-relevant stimuli.     

Effects of mand-tact versus tact-only training on the acquisition of tacts

We sought to replicate and extend Carroll and Hesse's (1987) study of the acquisition of tacts by including participants with and without developmental disabilities. As in Carroll and Hesse, the present results showed that mand-tact training, rather than tact-only training, led to more rapid acquisition of tacts. Tacting on follow-up tests did not differ. In addition, our results show that mand-tact training established both verbal operants involved about as rapidly as tact-only training established only one verbal operant. DESCRIPTORS: verbal behavior, tact acquisition, mand-tact training, tact-only training, follow-up     

Psychological characteristics of elderly insomniacs

Sixty insomniacs, aged 60 years or over, fulfilling the DSM-IV criteria for primary insomnia, completed a set of questionnaires measuring psychological distress. These included the Sleep Impairment Index (SIM), the Symptom Check List 90-Revised (SCL-90-R), the Penn State Worry Questionnaire (PSWQ), the Toronto Alexithymia Scale-20 (TAS-20) and the Elders Life Stress Inventory (ELSI). The insomniacs were compared on these measures with two contrast groups, one of elderly good sleepers and one an elderly community sample. As norms were developed for the SCL-90-R and PSWQ, insomniacs were also contrasted with the norm groups on these measures. In general, the results indicated a higher level of psychological distress among insomniacs than among the good sleepers, while there were negligible differences between insomniacs and the community sample on most measures. Overall, elderly insomniacs scored higher on measures of worry compared with the other groups, followed by measures of somatization, obsessive-compulsion and depression. It is concluded that excessive worrying was the most characteristic feature of elderly insomniacs.     

Infant responsiveness and maternal confidence in the neonatal period

Responsiveness in prematurely and term-born infants was studied cross-sectionally in relation to maternal confidence. Orientation and arousal were measured in 140 prematurely (mean BW 1,398 g, GA 30.1 weeks) and 75 term-born infants (mean BW 3,613 g, GA 39.3 weeks) with the Neonatal Behavioral Assessment Scales. Mothers filled out the Maternal Confidence Questionnaire and a modified version of the Parenting Stress Index. Prematurely born infants had a significantly lower level of arousal than term-born neonates. Responsiveness was not associated with maternal confidence. Lower confidence was associated with primiparity in both groups of mothers. Multiparous mothers of prematurely born infants had significantly lower levels of confidence than multiparous mothers of term-born infants. Confidence was significantly associated with stress for mothers of prematurely and term-born infants, and may be focused in follow-up after giving birth. Prematurely born infants should be examined more thoroughly in aspects of arousal at the time of discharge.     

Effects of training on age estimation

This study examined the possibility to improve accuracy of age estimates through training. Thirty‐four participants were divided into an experimental and a control group. The sessions included a pre‐test before training, six feedback or no‐feedback training tests and a post‐test after training. The experimental group performed the feedback tests and the control group the no‐feedback tests. Training was found to improve age estimation accuracy, particularly estimations of old stimuli, and training with feedback seemed to be superior to training without feedback. No difference was found between the groups at pre‐test, but at post‐test the experimental group exhibited greater accuracy in age estimation. Moreover, the experimental group increased its accuracy between the pre‐ and post‐tests. Copyright © 2006 John Wiley & Sons, Ltd.
