ILLUSION OF CONTROL:

Abstract— Experiments in which subjects are asked to analytically assess response-outcome relationships have frequently yielded accurate judgments of response-outcome independence, but more naturalistically set experiments in which subjects are instructed to obtain the outcome have frequently yielded illusions of control. The present research tested the hypothesis that a differential probability of responding p (R), between these two traditions could be at the basis of these different results. Subjects received response-independent outcomes and were instructed either to obtain the outcome (naturalistic condition) or to behave scientifically in order to find out how much control over the outcome was possible (analytic condition). Subjects in the naturalistic condition tended to respond at almost every opportunity and developed a strong illusion of control. Subjects in the analytic condition maintained their p (R) at a point close to 5 and made accurate judgments of control. The illusion of control observed in the naturalistic condition appears to be a collateral effect of a high tendency to respond in subjects who are trying to obtain an outcome, this tendency to respond prevents them from learning that the outcome would have occurred with the same probability if they had not responded.     

A partially ordered extention of the integers

This paper presents a monotonic system of Post algebras of order +* whose chain of Post constans is isomorphic with 012 ... -3-2-1. Besides monotonic operations, other unary operations are considered; namely, disjoint operations, the quasi-complement, succesor, and predecessor operations. The successor and predecessor operations are basic for number theory.The editing of this unified version of two previous papers [Epstein, Rasiowa 1990, 1991] by the authors was completed, except for footnotes, while the first author visited at Warsaw University during June–July, 1994. The footnotes were added by the first author in September, 1994.Presented byRyszard Wójcicki     

Multidimensional signal detection analyses (MSDA) for testing separability and independence: A Pascal program

A Pascal (Turbo 6.0) program for testing perceptual separability, decisional separability, and perceptual independence—three types of independence defined in the context of general recognition theory (GRT)—is presented. GRT is essentially a multidimensional extension of signal detectability theory (Green & Swets, 1966) and has been employed in complete-identification experimental paradigms to examine whether information processing of stimulus dimensions is perceptually and/or decisionally separable and/or perceptually independent. The definitions of these different forms of “independence” are provided, the experimental design is described, and the program, MSDA, is described and demonstrated.     

On estimation and hypothesis testing problems for correlation coefficients

A selection of statistical problems commonly encountered in psychological or psychiatric research concerning correlation coefficients are re-evaluated in the light of recently developed simplifications in the forms of the distribution theory of the intraclass correlation coefficient (exact theory), of the product-moment correlation coefficient and of the Spearman rank correlation coefficient (approximate).     

Secondary school professionals' ability to identify depression in adolescents

Adolescent depression represents a growing concern for secondary school personnel. Depression is often related to suicide, which currently ranks as the second leading cause of death in adolescents. Since secondary school personnel should be able to identify characteristics of adolescent depression, the purpose of this study was to assess regular classroom teachers', guidance counselors', and special education teachers' ability to identify characteristics of adolescent depression. Results indicated that counselors possess the greatest knowledge of these characteristics, while regular and special education teachers are somewhat less able to identify them. Results are discussed in terms of training and evaluation issues for teachers.     

The Association Between Self-Critical Rumination and Parenting Stress: The Mediating Role of Mindful Parenting

Self-critical rumination is a type of rumination focused on the content of self-critical thoughts. Although self-criticism and rumination are two maladaptive psychological processes with a negative effect on parenting, including parenting stress, the role of self-critical rumination on parenting outcomes has never been explored. The aim of this study is to analyze the role of self-critical rumination on parenting stress and examine whether mindful parenting dimensions (listening with full attention, compassion for the child, non-judgmental acceptance of parental functioning, emotional awareness of the child, and self-regulation in parenting) mediate this association. The moderating role of child’s age in the direct and indirect effects was also examined. A sample of 265 Portuguese mothers of children/adolescents from the general community completed measures of self-critical rumination, mindful parenting, and parenting stress. Self-critical rumination was negatively associated with all mindful parenting dimensions and positively associated with parenting stress. However, only non-judgmental acceptance of parental functioning and emotional awareness of the child dimensions were significant mediators of the relationship between self-critical rumination and parenting stress. The link between self-critical rumination and parenting stress as well as the indirect effects were not moderated by the child’s age. This study identifies an important maladaptive psychological process (self-critical rumination) that explains individual differences in parenting and a mechanism that may account for the link between self-critical rumination and parenting stress, which can both be modified through intervention.     

The Network Structure of Childhood Psychopathology in International Adoptees

International adoptees are at an increased risk of emotional and behavioral problems, especially those who are adopted at an older age. We took a new approach in our study of the network structure and predictability of emotional and behavioral problems in internationally adopted children in Finland. Our sample was from the on-going adoption study and comprised 778 internationally adopted children (387 boys and 391 girls, mean age 10.5 (SD 3.4) years). Networks were estimated using Gaussian graphical models and lasso regularization for all the children, and separately for those who were adopted at different ages. The results showed that anxiety/depressive symptoms, social problems, and aggressiveness were the most central symptom domains. Somatic symptoms were the least central and had the weakest effect on the other domains. Similarly, aggressiveness, social problems, and attention problems were high in terms of predictability (73–65%), whereas internalizing problems were relatively low (28–56%). There were clear but local age-group differences in network structure, symptom centrality, and predictability. According to our findings, network models provide important additional information about the centrality and predictability of specific symptom domains, and thus may facilitate targeted interventions among international adoptees.     

A systematic review of psychoneuroimmunology-based interventions

Psychoneuroimmunology-based interventions are used to attenuated disease progression and/or side effects of pharmacological treatment. This systematic review evaluates the different therapeutic and/or clinical psychoneuroimmunology-based interventions associated to both psychological, neuroendocrine and immunological variables. The review was conducted for all English, Portuguese and Spanish language articles published between 2005 and 2015. Independent investigators analyzed 42 studies concerning human psychoneuroimmunology-based interventions. Decreased levels of cortisol, epinephrine and norepinephrine (stress-related hormones) were associated to interventions like yoga, meditation, tai chi, acupuncture, mindfulness, religious/spiritual practices, cognitive behavior therapy, coping and physical exercises. Moreover, those interventions were also associated to reductions in inflammatory processes and levels of pro-inflammatory cytokines in cancer, HIV, depression, anxiety, wound healing, sleep disorder, cardiovascular diseases and fibromyalgia. Despite the associations between PNI variables and clinical/therapeutic interventions, only one study evidenced significant effects on a disease progression.     

<Emphasis Type="Italic">Recta Ratio Agibilium</Emphasis> in a medical context: the role of virtue in the physician-patient relationship

Acting for the good of the patient is the most fundamental and universally acknowledged principle of medical ethics. However, given the complexity of modern medicine as well as the moral fragmentation of contemporary society, determining the good is far from simple. In his philosophy of medicine, Edmund Pellegrino develops a conception of the good that is derived from the internal morality of medicine via the physician-patient relationship. It is through this healing relationship that rights, duties, and privileges are defined for both physicians and patients. Moreover, this relationship determines the characteristics or virtues that are necessary to engage in the medical telos. This paper addresses the role of the moral virtues in clinical medicine and the physician-patient relationship. First, it provides a brief background of the Aristotelian foundations of virtue-ethics. Second, it delves into Pellegrino’s philosophy of medicine understood as a practice oriented towards a teleological goal. Third, it relates the telos of medicine to the notion of the medical community as a fundamentally moral community. Finally, it concludes with a section that creates a dialogue between virtue ethics and principlism.     

Sympathetic reactivity in late pregnancy is related to labour onset in women

Stress regulation during pregnancy is considered to be connected to the timing of labour initiation. Although increasing knowledge is emerging on the regulation of parturition, there is currently no way to predict the start of spontaneous labour in women. The main aim of this study was to assess pain threshold and the sympathetic nervous system response to cold pain in relation to the onset of labour in healthy pregnant women. Ninety-three pregnant women were recruited and assessed for skin conductance (SC) activity during a cold pressor test in gestational week 38. Pain threshold and cold endurance were also measured and the results were compared with data obtained from hospital records. Seventy-four women had a spontaneous labour onset and a valid SC measurement. SC activity during the cold pressor test decreased significantly with the number of days left to spontaneous parturition. This may indicate a gradual decrease in sympathetic autonomic nervous system reactivity even during the last weeks of pregnancy. Measuring SC activity during mild stress provocation is a rapid and non-invasive means to study variation in sympathetic reactivity during pregnancy, and may be useful in research on stress regulation in pregnancy and its relation to labour initiation.
