The autoshaping procedure as a residual block clock

In the first experiment, 4 pigeons were each presented with a recurring sequence of four key colors followed by the delivery of grain (block clock). Once the rate of pecking had stabilized, three of the colors were replaced, during different series of sessions, by a darkening of the key. The rate of pecking was reduced within those segments of the interval between deliveries of food during which the key was dark; when the key was dark during the final portion of the interval, rates were reduced throughout the entire interval. In the second experiment, 3 new pigeons were exposed to a different sequence of colors, and the final stimulus was replaced in successive conditions by a novel color, a darkened key, and a restoration of the original color. The data indicated that darkening the key had a more severe, more extensive, and more persistent effect than did a mere change in color. These results suggest that it may be fruitful to conceptualize the autoshaping procedure as a special version of the block clock in which pecking is suppressed throughout the greater part of the interval by darkening the key. In the final condition, the same stimulus appeared in each of the last three portions of the interval. The rate of pecking was lower during the last two portions than when distinctive colors were presented, with the peak rate now appearing in the fifth of seven equal temporal components.     

Direct and continuous measurement of relational learning in human pavlovian conditioning

Three experiments were conducted employing a continuous measure of conditional stimulus/unconditional stimulus (CS/US) contingencies as perceived by the subject (i.e., subjective contingency or SC). It is argued that direct measurement of relational learning, as indexed by SC, can lead to a better understanding of Pavlovian conditioning processes. The first two experiments applied this approach to a methodologic controversy, raising the debate from a procedure-based argument to testing what the subject actually learns about CS/US relationships. While the issue was not resolved, testable hypotheses for future research were generated from the data. The third experiment contrasted the contingency stimulus-stimulus (S-S) account of Pavlovian conditioning with an earlier stimulus-response (S-R) continguity-reinforcement account. In this experiment, both SC and skin resistance were measured. Evidence for the existence of both cognitive-propositional and response-learning processes in conditioning was obtained.     

Treatment Effectiveness of PMTO for Children's Behavior Problems in Iceland: Child Outcomes in a Nationwide Randomized Controlled Trial

Well‐documented treatment methods must be tested following their implementation in community service agencies and across different cultures to ensure continuing effectiveness. This study was a randomized controlled trial (RCT) of Parent Management Training—the Oregon model (PMTO), conducted within a nationwide implementation in Iceland. Families of 102 clinically referred children with behavior problems were recruited from five municipalities throughout Iceland. Child age ranged from 5 to 12; 73% were boys. Families were randomly assigned to either PMTO or services usually offered in the communities (SAU). Child adjustment was measured with a latent construct based on parent, child, and teacher reports of externalizing and internalizing problems and social skills. Prepost intent‐to‐treat analyses showed that PMTO treatment led to greater reductions in child adjustment problems relative to the comparison group, obtaining a modest to medium effect size based on the construct score. Only one indicator (parent‐rated Social Skills) showed significant change independently and information on amount and kind of treatment in the SAU was limited. Overall, findings indicate that PMTO is an effective method to treat children's behavior problems in a Northern European culture and supply evidence for the method's successful implementation in community settings in Iceland. This is one of few nationwide implementation studies of PMTO outside the United States and the first RCT in Iceland to test a treatment model for children's behavior problems.     

Belastungen in der Kindheit und in der Jugend Essgestörter

Depending on definition and sample, a minority of varying size of women with eating disorders report to be victims of sexual and/or physical abuse. These stressful experiences are risk factors for mental disorders in general and not specifically for eating disorders. Parental high expectations and pre-morbid negative self-evaluation seem to be specific risk factors for anorexia nervosa and bulimia nervosa. Probably, patients with bulimia nervosa suffered more childhood adversity than those with restrictive anorexia nervosa. Patients with a history of sexual and/or physical abuse may be more severely ill and more difficult to treat than other patients with eating disorders. Careful questioning about childhood adversity seems advisable. In therapy, maintaining factors—like problems of self-esteem—are more important than predisposing or precipitating factors. For prevention, it is recommended to provide for the safety of children when treating their parents with mental illness—particularly substance use disorders—and to avoid parental high expectations.     

Argumentation: The Mixed Game

The paper introduces a new model of argumentation, the Mixed Game Model, that no longer separates rule-governed competence from actual performance but starts from human beings and their ability of competence-in-performance. Human beings are able to orientate themselves in ever-changing surroundings and to negotiate diverging views in argumentative action games. Argumentation is thus described as a mixed game played by human beings according to principles of probability. These principles include constitutive, regulative and executive principles. Constitutive Principles focus on the basic components of the game, that is, action, dialogue, and coherence as the interplay of different communicative means. Regulative Principles mediate between correlated human abilities and interests. Executive Principles guide the sequencing of action according to cognitive strategies. The mixed game no longer rests on pre-established harmony but describes performance as a non-equilibrial process of negotiation that mediates between order and disorder and is based on the integration of various parameters such as rationality, reason, persuasion and emotion. How the model works is exemplified by an analysis of part of a debate in the European Parliament.     

Implementation of Parent Management Training—Oregon Model (PMTOTM) in Iceland: Building Sustained Fidelity

Bringing empirically supported treatments (ESTs) into community settings is a challenge because of threats to therapy adherence. The nationwide implementation of Parent Management Training—the Oregon Model (PMTO) in Iceland was studied by comparing therapists' competent adherence to PMTO across three generations of therapists. To assess therapists' competence and adherence to the PMTO method, the Fidelity of Implementation Rating System (FIMP) was used as the measuring device. Of 16 therapists across three generations who entered training, 12 completed with certification. As expected, each of the three generations obtained adequate FIMP scores. Generations 1 and 3 showed equivalent levels of performance on FIMP scores at certification. A small drop in FIMP scores for Generation 2 was explained in terms of translating and culturally adjusting materials and strengthening training procedures. Results are parallel to earlier findings from the nationwide PMTO implementation in Norway and support the idea that PMTO can be implemented in community settings with high fidelity even when resources are scarce.     

‘Joining into God's breath’: travail of the negative as a connection between mysticism and political activism

This essay argues that a negative hermeneutics, i.e., a hermeneutics that takes its starting point from the experience of gaps, failures, and limits, is a suitable lens for the study of mysticism. It uses the concept of travail of the negative, which focuses on the dynamics of a continuous ‘unsaying’ and ‘subverting’ of traditional expressions of faith and religious practice, to explore the connection between aspects of practical and theoretical negativity in mystical expressions. It suggests that this approach to mystical theology makes an important contribution to the wider theological discourse and encourages theology to take the fundamental character of negation seriously.     

Relations between mental performance and reaction time: New aspects of an old problem

The relation between simple and complex reaction time and psychometrically determined mental performance was reexamined with 486 subjects of above-average intelligence. Various standardized tests measuring aspects of cognitive ability, memory and ability to concentrate were used. Simple and complex reaction times were measured using the Klebelsberg modification of the Mierke apparatus. Correlations between complex reaction time and mental performance as observed by other investigators were mostly confirmed. We found, however, the strongest and most consistent correlations with tests measuring short-term memory; ability to concentrate and spatial ability. On the other hand, tests known and shown again in this paper to load highly on Spearman's general factor g, such as verbal abilities; combinatoric thinking; abstraction; or calculation gave only trivial, and, in most cases, nonsignificant correlations with complex reaction time. We even observed a negative (though, for our data, not significant) correlation between g-loadings of subtests and their correlations with complex reaction time for the only complete standardized intelligence test used in this study, the “Intelligenz-Strukturtest (Amthauer).” Therefore, this study does not support the hypothesis that fast processing of complex information as measured by complex reaction time is the decisive component of the general factor of intelligence g.     

Treatment effectiveness of PMTO for children's behavior problems in Iceland: Assessing parenting practices in a randomized controlled trial

Findings are presented from an Icelandic randomized control trial (RCT) evaluating parent management training – Oregon model (PMTO?), a parent training intervention designed to improve parenting practices and reduce child behavior problems. In a prior report from this effectiveness study that focused on child outcomes, children in the PMTO condition showed greater reductions in reported child adjustment problems relative to the comparison group. The present report focuses on observed parenting practices as the targeted outcome, with risk by treatment moderators also tested. It was hypothesized that mothers assigned to the PMTO condition would show greater gains in pre‐post parenting practices relative to controls. The sample was recruited from five municipalities throughout Iceland and included 102 participating families of children with behavior problems. Cases were referred by community professionals and randomly assigned to either PMTO (n = 51) or community services usually offered (n = 51). Child age ranged from 5 to 12 years; 73% were boys. Contrary to expectations, findings showed no main effects for changes in maternal parenting. However, evaluation of risk by treatment moderators showed greater gains in parenting practices for mothers who increased in depressed mood within the PMTO group relative to their counterparts in the comparison group. This finding suggests that PMTO prevented the expected damaging effects of depression on maternal parenting. Failure to find hypothesized main effects may indicate that there were some unobserved factors regarding the measurement and a need to further adapt the global observational procedures to Icelandic culture.
