My Scholarly Life in Cybernetics

This article narrates how I discovered cybernetics, who inspired me to make the contributions of which I am proud, and the ideas that led me to recognize the importance of understanding the social world we live in as a consequence of what we do in language. It took me some time before I recognized that circular causality and digitalization that made cybernetics the driver of the current revolution toward a computationally autonomous information society had serious limitations. When used to explain human involvements, the mathematics of cybernetics trivializes what we do to each other and blinds us to recognize how cybernetics transformed society. Studying conversations and discourses made me aware of how cybernetic vocabularies, guiding concepts, and computational metaphors were enacted. By contrast to (first- or second-order) cybernetics, I learned that a cybernetics that is practiced in conversations and acknowledges the social consequences of what it generates had to be reflexive. Shifting attention from causal circularities to reflexive circularities opens up huge new areas for exploring socially meaningful contributions and criticizing the epistemologies of mindless discursive practices (e,g., of claiming the superiority of artificial intelligence and the power of computers). Such claims merely entrap their believers into inaction.     

Self-Attributed Importance of Spiritual Practices in Catholic Pastoral Workers and their Association with Life Satisfaction

Although much is known about the frequency of the spiritual activities of pastoral workers, less is known related to how important specific spiritual and existential practices are to pastoral workers personally or existentially. This part of the German Pastoral Ministry Study analyzed (1) which forms of spiritual activities were regarded as important, (2) how the perceived importance of religious practices related to frequency of engagement in spiritual practices, and (3) how these practices contributed to the life satisfaction of ordained priests and of non-ordained pastoral workers. Participants included 1826 Catholic pastoral workers, composed of 65% priests and 35% (non-ordained) pastoral assistants and parish expert workers. Prosocial-Humanistic practices scored highest in importance, followed by Gratitude/Awe, Existentialistic practices, and Religious practices; specific forms of Spiritual Mind-Body practices were not relevant. Differences in the frequency and ascribed importance of spiritual practices between ordained and non-ordained pastoral workers were identified, as well as a surprising lack of connection between religious practices and their proclaimed importance, particularly of Prosocial-Humanistic and Gratitude/Awe practices. These findings may stimulate further research into the underlying causes of these differences between priests and other pastoral workers and between the frequency and importance of spiritual practices in all groups, which in the researchers’ opinion indicate challenging inconsistencies with regard to the ideals of religious vocations.     

<Emphasis Type="Italic">Ceteris</Emphasis>-<Emphasis Type="Italic">Paribus</Emphasis> Qualifiers

Antecedent-strengthening, a trivially valid inference of classical logic of the form: P → Q ? (P & R) → Q, has a counterpart in everyday reasoning that often fails. A plausible solution to the problem involves assuming an implicit ceteris paribus (CP) qualifier that can be explicated as an additional conjunct in the antecedent of the premise. The qualifier can be explicated as ‘everything else relevant remains unchanged’ or alternatively as ‘nothing interferes’. The qualifier appears most prominently in the context of the discussion of laws in the sciences, where these laws are often expressed with a CP qualifier. From an analysis of the qualifier’s role in the problem of antecedent-strengthening, we can learn more about CP qualifiers in general and in their application to the laws used in the sciences.     

Stereotypes as Pseudocontingencies

We introduce a heuristic called pseudocontingencies (PCs) as an alternative account of various stereotyping phenomena. PCs give rise to the expectation that attributes are correlated based solely on asymmetries in attribute base rates. Attributes that are encountered frequently and attributes that are encountered rarely are perceived to be correlated with each other. Such differences in information densities are typical of many stereotyped targets, including the self vs. others, the in-group vs. out-groups and majority vs. minority groups. Evidence is reviewed for PCs underlying illusory correlations, confirmation biases, gender stereotypes, Simpson’s paradox, and in procedures used for implicit stereotype measurement. PCs are shown to predict specific patterns of self-enhancement and self-depreciation, the effects of intergroup contact on in-group biases and the readiness to infer stereotypes from aggregated “big-data”. Although PCs can lead to seriously flawed stereotypic expectations, they afford an efficient and possibly adaptive inference strategy.     

Interpreting ambiguous stimuli: Separating perceptual and judgmental biases

Interpreting ambiguous situations is not a purely data-driven process but can be biased towards positive interpretations by top-down influences. The present study tries to identify the underlying processes of these top-down influences. There are two separable types of processes that can be influenced by motivational biases: A perceptual bias affects information uptake whereas a judgmental bias affects acceptance criteria for positive and negative outcomes. In the present study, motivated influences on perception and judgment were investigated with a simple color discrimination task in which ambiguous stimuli had to be classified according to their dominating color. One of two colors indicated a financial gain or a loss, whereas a third color was neutral. To separate perceptual and judgmental biases, Ratcliff’s [Ratcliff, R. (1978). A theory of memory retrieval. Psychological Review, 85, 59–108] diffusion model was employed. Results revealed motivational influences on perception and judgment.     

Electrophysiological markers of visual dimension changes and response changes

In cross-dimensional visual search tasks, target discrimination is faster when the previous trial contained a target defined in the same visual dimension as the current trial. The dimension-weighting account (DWA; A. Found & H. J. Müller, 1996) explains this intertrial facilitation by assuming that visual dimensions are weighted at an early perceptual stage of processing. Recently, this view has been challenged by models claiming that intertrial facilitation effects are generated at later stages that follow attentional target selection (K. Mortier, J. Theeuwes, & P. A. Starreveld, 2005). To determine whether intertrial facilitation is generated at a perceptual stage, at the response selection stage, or both, the authors focused on specific event-related brain potential components (directly linkable to perceptual and response-related processing) during a compound search task. Visual dimension repetitions were mirrored by shorter latencies and enhanced amplitudes of the N2-posterior- contralateral, suggesting a facilitated allocation of attentional resources to the target. Response repetitions and changes systematically modulated the lateralized readiness potential amplitude, suggesting a benefit from residual activations of the previous trial biasing the correct response. Overall, the present findings strengthen the DWA by indicating a perceptual origin of dimension change costs in visual search.     

Psychosocial Family Treatment for a 10-Year-Old with Schizoaffective Disorder

Schizophrenia spectrum disorders are rare in childhood and little is known about their psychosocial treatment. Relevant findings from the adult and child literature are reviewed. The case of 10-year-old “Michael” is presented, who participated in a randomized clinical trial of a psychoeducational family treatment for mood disorders. Following treatment, quantitative and qualitative data show that Michael's mood and social functioning improved, utilization of mental health services improved, the overall family emotional climate became more positive, and his parents felt supported. He no longer met criteria for a mood episode but continued to display psychosis. This family's response suggests that group psychoeducation may be an effective treatment for families of children with emerging schizophrenia spectrum disorders.
