Perfectionism and efficiency: Accuracy,response bias,and invested time in proof-reading performance

Investigating problem-solving performance, Ishida, H. (2005). College students’ perfectionism and task-strategy inefficience: Why their efforts go unrewarded? Japanese Journal of Social Psychology, 20, 208–215. Found high levels of perfectionism were associated with lower efficiency. Aiming to replicate and further explore this finding, the present study investigated how two dimensions of perfectionism (high standards, discrepancy between expectations and performance) predicted efficiency in proof-reading performance. N = 96 students completed a proof-reading task involving the detection of spelling, grammar, and format errors. When error-detection performance was subjected to signal detection analysis, high standards correlated positively with the number of incorrectly detected errors (false alarms). Moreover, when task-completion time was taken into account, high standards were negatively correlated with efficiency (accuracy/time). In comparison, discrepancy correlated negatively with the number of correctly detected errors (hits) and positively with a conservative response bias. The findings show that perfectionistic standards are associated with reduced efficiency demonstrating the importance of considering invested time, errors, and response bias when investigating the relationship between perfectionism and performance.     

Comparison of automated procedures for ARMA model identification

This article evaluates the performance of three automated proceduresfor ARMA modelidentification commonly available in current versions of SAS for Windows: MINIC, SCAN, and ESACF. Monte Carlo experiments with different model structures, parameter values, and sample sizes were used to compare the methods. On average, the procedures either correctly identified the simulated structures or selected parsimonious nearly equivalent mathematical representations in at least 60% of the trials conducted. For autoregressive models, MINIC achieved the best results. SCAN was superior to the other two procedures for mixed structures. For moving-average processes, ESACF obtained the most correct selections. For all three methods, model identification was less accurate for low dependency than for medium or high dependency processes. The effect of sample size was more pronounced for MINIC than for SCAN and ESACE SCAN and ESACF tended to select higher-order mixed structures in larger samples. These findings are confined to stationary nonseasonal time series.     

Psychische Betreuung von Patienten und Angehörigen in der Transplantationsmedizin

During the decision making process and waiting period before organ transplantation patients and their families often suffer from psychological distress. After transplantation a subgroup of patients keeps showing psychological symptoms and also impairments of quality of life. Psychological treatment manuals are often demanded, but are rarely achieved. This study describes the experience with a low frequent (8 sessions/year) therapeutic group for lung transplant candidates. The group, which is based on a cognitive behavioural concept, is lead by a physician (internal medicine), a psychotherapist and a physiotherapist. This therapeutic group has been continuously offered for patients and their caregivers for the past 7 years. About 50% of all patients participated in this program before transplantation, after transplantation only a few patients visited the group sessions. On average 12 patients and 8 caregivers visited each session. One problem for these patients with severe lung-disease was the long distance between patient’s homes and the hospital. This has been the reason for self-help organisations to demand better psychotherapeutic outpatient support for patients and their families before and after organ transplantation.     

Shock without awe

In January 2011, the American Psychologist ran a special issue on "Comprehensive Soldier Fitness," edited by Martin Seligman and Michael Matthews. Thirteen articles described a collaborative effort by the U.S. Army and positive psychologists to "improve our force's resilience" (Casey, 2011, p. 1). If successful, one assumes, these efforts will make military engagements shorter (though not less frequent) and more victorious, while reducing human suffering on all sides. How can one object? Yet, the contributors themselves anticipated criticism. To justify their engagement with the military, they argued that psychological science has been relevant throughout its history, most notably during the world wars (Seligman & Fowler, 2011). They further noted that although the deployment of psychology may seem rushed, the exigency of the situation in the field demands it. Like other groups in conflict, the Army has an interest in standardizing the behavior of its members. To achieve this, the Army can threaten and deliver punishment. From the group's perspective, this interest is necessary and legitimate. It is, in the author's view, not legitimate for psychologists to obfuscate the conflict of interest between Army and soldier and to act as though they care, above all, about the well-being of the soldier.     

Reaching out for the object in the process of meeting

Reaching out for an object has been broadly discussed within psychoanalysis using the term 'object-seeking'. This article develops the idea that it is a fundamental feature of human beings to reach out for objects in order to survive and/or to gain vitality. Self-love, which is a derivative of object love, is not possible to achieve in a developmental manner without a sufficient phase-specific emotional response to the subject’s object seeking. In terms of psychoanalytic methodology, the present article represents a tradition (e.g. Tähkä) of renewal related to the classique approach, which is a more passive psychoanalytic technique (e.g. Freud and Winnicott). This traditional psychoanalytic methodology is complemented with a more active technique in order to be therapeutically efficient – especially in the treatment of individuals who are not primary neurotic. The four psychoanalytic schools (drive, object relations, ego and self-psychology) are integrated in a patient’s authentic attempt to reach out for the developmental object in the process of meeting.     

Cultural diversity in nanotechnology ethics

Along with the rapid worldwide advance of nanotechnology, debates on associated ethical issues have spread from local to international levels. However unlike science and engineering issues, international perceptions of ethical issues are very diverse. This paper provides an analysis of how sociocultural factors such as language, cultural heritage, economics and politics can affect how people perceive ethical issues of nanotechnology. By attempting to clarify the significance of sociocultural issues in ethical considerations my aim is to support the ongoing international dialogue on nanotechnology. At the same time I pose the general question of ethical relativism in engineering ethics, that is to say whether or not different ethical views are irreconcilable on a fundamental level.     

The specificity of temporal expectancy: evidence from a variable foreperiod paradigm

In speeded choice tasks with variable foreperiods (FPs), individuals behaviourally adapt to various frequency manipulations. Adaptations have been shown to frequencies of different stimulus-response events, to frequencies of different foreperiods, and to frequencies of different event-foreperiod combinations. We have investigated how participants adapt to a situation where all three frequency manipulations are done simultaneously. Three variable foreperiod experiments are reported. In Experiment 1, one target (the peak distributed target) appeared particularly frequently after one particular FP (the peak foreperiod), while another target was less frequent and equally distributed over all foreperiods. In Experiment 2, the equally distributed target was overall more frequent than the peak distributed one. In both experiments, performance advantages for the peak distributed target were specific to the peak foreperiod, and performance advantages at the peak foreperiod were specific to the peak distributed targets. A third experiment showed that, when two differently frequent target are both equally distributed over FPs, the performance distribution over FPs is not significantly different between both targets. Together, the results suggest that participants were able to simultaneously and specifically adapt to frequency manipulations in events, foreperiods, and event-foreperiod combinations.     

Problematic video game use: estimated prevalence and associations with mental and physical health

A nationwide survey was conducted to investigate the prevalence of video game addiction and problematic video game use and their association with physical and mental health. An initial sample comprising 2,500 individuals was randomly selected from the Norwegian National Registry. A total of 816 (34.0 percent) individuals completed and returned the questionnaire. The majority (56.3 percent) of respondents used video games on a regular basis. The prevalence of video game addiction was estimated to be 0.6 percent, with problematic use of video games reported by 4.1 percent of the sample. Gender (male) and age group (young) were strong predictors for problematic use of video games. A higher proportion of high frequency compared with low frequency players preferred massively multiplayer online role-playing games, although the majority of high frequency players preferred other game types. Problematic use of video games was associated with lower scores on life satisfaction and with elevated levels of anxiety and depression. Video game use was not associated with reported amount of physical exercise.     

Elements of trust: Risk and perspective-taking

Trust is essential to personal well-being and economic success, but it cannot occur without accepting the possibility of betrayal. In the experimental trust game, game-theoretic rationality prescribes that trust decisions should depend on the potential risk (egocentric costs and benefits) and the probability of reciprocity (derived from the trustee's temptation to defect). The current work tests the relative weights of these elements. Experiment 1 shows that trust increases when costs decrease and benefits increase. The latter finding is critical because increasing the trustor's benefit also means increasing the trustee's temptation to defect. Hence, this finding suggests that egocentrism prevails over perspective-taking. Experiment 2 shows that the trustee's temptation to defect (negatively) affects trust, but only when the trustor's cost and benefit are favorable. Results are interpreted as reflecting a boundedly rational decision process.     

Social perception as induction and inference: an integrative model of intergroup differentiation, ingroup favoritism, and differential accuracy

Three general properties of social stereotypes are the perception of differences between ingroups and outgroups (intergroup differentiation), the perception of ingroups as having more desirable attributes than outgroups (ingroup favoritism), and the greater accuracy of ingroup perceptions (differential accuracy). We present and test an inductive-reasoning model that accounts for all 3 phenomena, and we explicate the relations among them. Based on empirical evidence, the model assumes that most people have a positive self-image, that they project these self-images more strongly to ingroups than to outgroups, and that their self-images are valid cues for judgments about social groups. Two minimal-group experiments using a crossed-categorization paradigm support the model and provide new evidence for underlying psychological processes.
