Suicidal Behaviors in Surviving Monozygotic and Dizygotic Co‐Twins: Is the Nature of the Co‐Twin's Cause of Death a Factor?

Genetically informative samples can address hereditary and experiential influences on suicide‐related behaviors. The frequency of suicide‐related behaviors was compared in twins from two survivor groups: (1) those whose co‐twins' deaths were suicides (monozygotic [MZ]: n = 47; dizygotic [DZ]: n = 31), and (2) those whose co‐twins' deaths were nonsuicides (MZ: n = 347; DZ: n = 170). The frequency of suicide attempts among suicide survivors was significantly higher in MZ than DZ twins, while the frequency of suicide attempts among nonsuicide twin survivors did not differ between MZ and DZ twins. Twin concordance for suicide attempts more likely reflects a genetic predisposition than a behavioral reaction to the loss.     

Single-Stage Prediction Models Do Not Explain the Magnitude of Syntactic Disambiguation Difficulty

The disambiguation of a syntactically ambiguous sentence in favor of a less preferred parse can lead to slower reading at the disambiguation point. This phenomenon, referred to as a garden-path effect, has motivated models in which readers initially maintain only a subset of the possible parses of the sentence, and subsequently require time-consuming reanalysis to reconstruct a discarded parse. A more recent proposal argues that the garden-path effect can be reduced to surprisal arising in a fully parallel parser: words consistent with the initially dispreferred but ultimately correct parse are simply less predictable than those consistent with the incorrect parse. Since predictability has pervasive effects in reading far beyond garden-path sentences, this account, which dispenses with reanalysis mechanisms, is more parsimonious. Crucially, it predicts a linear effect of surprisal: the garden-path effect is expected to be proportional to the difference in word surprisal between the ultimately correct and ultimately incorrect interpretations. To test this prediction, we used recurrent neural network language models to estimate word-by-word surprisal for three temporarily ambiguous constructions. We then estimated the slowdown attributed to each bit of surprisal from human self-paced reading times, and used that quantity to predict syntactic disambiguation difficulty. Surprisal successfully predicted the existence of garden-path effects, but drastically underpredicted their magnitude, and failed to predict their relative severity across constructions. We conclude that a full explanation of syntactic disambiguation difficulty may require recovery mechanisms beyond predictability.     

Postnatal trajectories of maternal depressive symptoms: Postpartum antecedents and differences in toddler adjustment

Infants are uniquely vulnerable to maternal depression's noxious effects, but few longitudinal studies have tried to identify discrete postnatal trajectories of maternal depressive symptoms (MDS) beginning in infancy. This study extends evidence of heterogeneous change in postnatal MDS by examining their cross-contextual antecedents in infancy and their consequences for children's early behavior problems and language skills in late toddlerhood. A community sample of mother–child dyads (N = 235, 72% Caucasian) was assessed when children were 7, 15, and 33 months old. Mothers reported their socioeconomic status (SES), social support, marital relationship quality, family dysfunction, parenting stress, and infants’ functional regulatory problems at 7 months postpartum, and children's internalizing and externalizing symptoms at 33 months. Children completed a receptive vocabulary assessment at 33 months in the lab. Latent class growth analysis identified three postnatal MDS trajectory classes that fit the data best: low-decreasing, moderate, and increasing. Psychosocial measures at seven months postpartum primarily predicted membership to these postnatal trajectory classes, which subsequently differed in children's internalizing, externalizing, and receptive vocabulary in late toddlerhood, controlling for family SES and functional regulatory problems in infancy. We discuss salient antecedents and consequences of postnatal depression for mothers and their offspring.     

Proactive Vitality Management,Work Engagement,and Creativity: The Role of Goal Orientation

This study tested the hypothesis that individuals can proactively manage their own energetic, affective, and cognitive resources in order to be creative at work. Building on proactivity and creativity literatures, we propose a theoretical model in which employees who proactively manage their vitality are more engaged in their work and show improved creative performance. We also tested the boundary conditions of this process. Participants were Dutch employees from various occupations who filled out a background questionnaire and five weekly surveys. The results of multilevel modelling analyses offered support for our model. Weekly proactive vitality management was positively related to changes in weekly creativity through changes in weekly work engagement. As predicted, learning goal orientation strengthened and performance goal orientation weakened the links between proactive vitality management and engagement, and between engagement and creativity. We discuss the theoretical contributions, and indicate how these findings can be used in daily working life.     

Enactment as understanding and as misunderstanding

The author considers the concept of enactment as a ubiquitous event that is best seen as part of a sequence in the process of understanding a patient. As such, enactments are not unusual or special save as they are often subject to disavowal or to being singled out by the analyst as especially subject to scrutiny. Once recognized, enactments need to be interpreted: not so much in terms of their unconscious origins, but more with regard to the need to include them in the analytic dialogue.     

Reflections on creative aspects of psychoanalytic diagnosing

This paper explores the therapeutic value of considering psychoanalytic diagnoses as co-constructions, and emphasizes two interrelated points: First, there are distinctions between medical, psychiatric, and psychoanalytic diagnoses, and similarly, a distinction may be drawn between diagnoses as nouns and the activity of diagnosing. Second, the author stresses that psychoanalytic diagnoses are theory bound. Various competing theories facilitate or interfere with the maintenance of an optimal analytic attitude. Some theories facilitate an analyst's urge to engage in the activity of diagnosing, which may reflect a destructive countertransference enactment. Analytic data in support of these premises is presented and discussed.
