The Mandate of the Ecumenical Movement

This is the text of the address given by Willem A. Visser 't Hooft to the Uppsala Assembly of the World Council of Churches (WCC) in 1968 after being named honorary president of the WCC, following his retirement as general secretary two years earlier. In this address, Visser 't Hooft reviews the 20th‐century history of the ecumenical movement and the contemporary mandate of the WCC, in which the central issue is the relationship between the church and the world, where the vertical dimension to God of the church's unity determines the horizontal dimension of its service to the world. The address concludes with four challenges: no horizontal advance without vertical orientation; the ecumenical movement and the churches need each other; church unity is important; and youth expects answers.     

The impact of premature childbirth on parental bonding

The development of an affectionate parent-infant bond is essential for a newborn infant's survival and development. However, from evolutionary theory it can be derived that parental bonding is not an automatic process, but dependent on infants' cues to reproductive potential and parents' access to resources. The purpose of the present study was to examine the process of bonding in a sample of Dutch mothers (n = 200) and fathers (n = 193) of full-term (n = 69), moderately premature (n = 68), and very premature infants (n = 63). During the first month postpartum parents completed the Pictorial Representation of Attachment Measure (PRAM) and Postpartum Bonding Questionnaire (PBQ). Longitudinal analyses revealed that mothers' PRAM scores decreased after moderately preterm delivery, whereas decreases in PRAM scores occurred in both parents after very preterm delivery. As lower PRAM scores represent stronger feelings of parent-infant connectedness, our findings suggest a higher degree of bonding after premature childbirth. Results of the PBQ analysis were in line with PRAM outcomes, as parents of preterm infants reported less bonding problems compared to parents of full-terms. These findings support the hypothesis that in affluent countries with adequate resources, bonding in parents of preterm infants on average may be higher than in parents of full-term infants.     

Affective regulation of cognitive-control adjustments in remitted depressive patients after acute tryptophan depletion

Negative affect in healthy populations regulates the appraisal of demanding situations, which tunes subsequent effort mobilization and adjustments in cognitive control. In the present study, we hypothesized that dysphoria in depressed individuals similarly modulates this adaptation, possibly through a neural mechanism involving serotonergic regulation. We tested the effect of dysphoria induced by acute tryptophan depletion (ATD) in remitted depressed patients on conflict adaptation in a Simon task. ATD temporarily lowers the availability of the serotonin precursor L-Tryptophan and is known to increase depressive symptoms in approximately half of remitted depressed participants. We found that depressive symptoms induced by ATD were associated with increased conflict adaptation. Our finding extends recent observations implying an important role of affect in regulating conflict-driven cognitive control.     

Redundant sensory information does not enhance sequence learning in the serial reaction time task

In daily life we encounter multiple sources of sensory information at any given moment. Unknown is whether such sensory redundancy in some way affects implicit learning of a sequence of events. In the current paper we explored this issue in a serial reaction time task. Our results indicate that redundant sensory information does not enhance sequence learning when all sensory information is presented at the same location (responding to the position and/or color of the stimuli; Experiment 1), even when the distinct sensory sources provide more or less similar baseline response latencies (responding to the shape and/or color of the stimuli; Experiment 2). These findings support the claim that sequence learning does not (necessarily) benefit from sensory redundancy. Moreover, transfer was observed between various sets of stimuli, indicating that learning was predominantly response-based.     

Facets of autobiographical memory in adolescents with major depressive disorder and never‐depressed controls

Adolescence is a crucial developmental window because it involves elaboration of the self‐concept, the laying down of lifelong autobiographical memories, and the development of emotional resilience during a time of substantial risk for mood problems. Autobiographical memory retrieval plays an important role in depression both in adults (van Vreeswijk & de Wilde, 2004 van Vreeswijk, MF and de Wilde, EJ. (2004). Autobiographical memory specificity, psychopathology, depressed mood and the use of the Autobiographical Memory Test: a meta‐analysis. Behaviour Research and Therapy, 42: 731–743. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and adolescents (Kuyken, Howell, & Dalgleish, 2005; Park, Goodyer, & Teasdale, 2002 Park, RJ, Goodyer, IM and Teasdale, JD. (2002). Categoric overgeneral autobiographical memory in adolescents with major depressive disorder. Psychological Medicine, 32: 267–276. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). This study examined facets of autobiographical memory associated with memory retrieval in never‐depressed and currently depressed adolescents: personal importance, imagery, recency, source monitoring, and field‐observer perspective. Compared with never‐depressed adolescents, adolescents with depression were significantly more likely to retrieve memories from an observer perspective and more recent time period, preferentially rehearsed negative memories and rated their memories as more personally important. Depressed adolescents who reported a history of trauma retrieved more vivid autobiographical memories than depressed adolescents not reporting such a history, had rehearsed them more frequently, and reported more confidence in their veracity.     

Bridging developmental systems theory and evolutionary psychology using dynamic optimization

Interactions between evolutionary psychologists and developmental systems theorists have been largely antagonistic. This is unfortunate because potential synergies between the two approaches remain unexplored. This article presents a method that may help to bridge the divide, and that has proven fruitful in biology: dynamic optimization. Dynamic optimization integrates developmental systems theorists’ focus on dynamics and contingency with the ‘design stance’ of evolutionary psychology. It provides a theoretical framework as well as a set of tools for exploring the properties of developmental systems that natural selection might favor, given particular evolutionary ecologies. We also discuss limitations of the approach.     

Kristallnacht: Experiencing Nazi Germany

Lore Zeller, long-time friend and proofreader of Psychological Perspectives, is a first-time contributor to our journal—or any journal. Lore is also something of an icon at the bookstore of the C.G. Jung Institute of Los Angeles, where she has worked, dispensing books and wisdom, for over twenty years. She is eighty-seven years old. Over the past few years she has translated all of the correspondence from her German-Jewish parents and in-laws after she, her husband, and their two-year-old son fled their hometown of Berlin to seek safety in the United States via England. Within a few years of their escape, both sets of parents had perished in death camps. As survivors in Los Angeles, her husband and she helped found the Jung Institute here.

When she mentioned that she had been working on this paper, it was suggested she send it to us for review. After giving the idea some consideration, she eventually overcame her innate shyness — the results of which can be seen in the riveting story that follows.

Dimensions of temperament and depressive symptoms: Replicating a three-way interaction

High negative emotionality (NE), low positive emotionality (PE), and low self-regulatory capacity (i.e., effortful control or EC) are related to depressive symptoms and furthermore, may moderate one another’s relations to such symptoms. Indeed, preliminary evidence suggests they may operate in a three-way interaction (Dinovo & Vasey, 2011), but the replicability of that finding remains unknown. Therefore, we tested this NE × PE × EC interaction in association with depressive symptoms in 5 independent samples. This interaction was significant in 4 of the 5 samples and a combined sample and approached significance in the fifth sample. In contrast, the NE × PE × EC interaction was unrelated to general anxious symptoms and thus may be specific to symptoms of depression. Implications, directions for future research, and limitations are discussed.     

Willful Ignorance

Michelle Moody-Adams suggests that “the main obstacle to moral progress in social practices is the tendency to widespread affected ignorance of what can and should already be known.” This explanation is promising, though to understand it we need to know what willful (affected, motivated, strategic) ignorance actually is. This paper presents a novel analysis of this concept, which builds upon Moody-Adams (1994) and is contrasted with a recent account by Lynch (2016).     

Sadism linked to loneliness: psychodynamic dimensions of the sadistic serial killer Jeffrey Dahmer

In this article the psychodynamic link between loneliness and sadism is examined on basis of a case report of the sadistic and cannibalistic serial killer Jeffery Dahmer. Envy, shame/rage mechanism, a disturbed oral-sadistic development, castration fear and severe feelings of inferiority, the conviction of being unlovable and unacceptable, need to diminish tension, powerful and sadistic fantasies as a consequence of inadequate and frustrated parenting, and reality distortion appear to be involved in sadistic etiology.
