Disruption in Pavlovian-Instrumental Transfer as a Function of Depression and Anxiety

The Pavlovian-Instrumental Transfer (PIT) paradigm examines probabilistic and reinforcement learning. Disruptions in mechanisms that mediate PIT (i.e., cues not triggering adaptive behaviors) are thought to be contributors to psychopathology, making the study of probabilistic and reinforcement learning clinically relevant. The current study evaluated an appetitive PIT effect and its relationship with symptom dimensions spanning depression and anxiety, with a particular focus on anhedonia. Forty young adults ranging in scores across dimensions of depression and anxiety symptoms completed the PIT paradigm and self-report symptom measures. The PIT paradigm consisted of three phases. The instrumental phase consisted of a contingent association in which participants squeezed a handgrip for monetary reward. The Pavlovian phase established a purely predictive association between three visual stimuli (CS?+?, CS-, baseline) and presence or absence of monetary reward. In the transfer phase, participants’ responses allowed for examination of whether motivational characteristics of Pavlovian predictors influenced the vigor of their handgrip squeezes (instrumental action), which were formerly independent of Pavlovian associations. Analyses revealed a baseline-reward PIT effect, whereby a reward-associated Pavlovian cue enhanced instrumental responding in the transfer phase. However, there were no significant differences between CS?+?and CS- or CS- and baseline cues, suggesting a disrupted interaction of Pavlovian and instrumental learning. Further, the appetitive PIT effect captured in this paradigm was not associated with anhedonia, fears, or general distress. Future work should investigate the influence of mood states using more specific appetitive PIT paradigms to further understanding of the implications of disrupted reflexive and instrumental responding.

     

Reducing Escape without Escape Extinction: A Systematic Review and Meta-Analysis of Escape-Based Interventions

Individuals with disabilities may engage in challenging behavior to escape aversive stimuli, like academic tasks or non-preferred foods. Interventions to reduce these behaviors often employ escape extinction; that is, the implementer withholds escape following challenging behavior. Escape extinction can increase risk of injury, restrict autonomy, and worsen the learner–implementer relationship. To mitigate collateral effects, interventions can use strategies without escape extinction (i.e., escape-based); that is, implementers can provide escape contingent on challenging behavior during intervention, in conjunction with other intervention components. However, no comprehensive syntheses of these interventions have been conducted. We identified 39 articles that included escape-based interventions, which contained 273 single-case designs. Escape-based interventions were associated with lower levels of challenging behavior and higher levels of adaptive behavior than baseline conditions. Most comparisons between escape-based and escape extinction interventions showed no functional relation, indicating that escape extinction may not add substantial benefit to intervention efficacy.

Attention Bias for Threatening Information in Children Following a Distressing Medical Procedure

Attention bias is common in adults with post‐traumatic stress disorder (PTSD) but is less studied in children. Children (n = 22) who experienced a potentially distressing procedure in an outpatient clinic (removal of K‐wires from orthopaedic fractures) and a group of medically unwell children (illness group; n = 27) were compared with healthy controls (n = 32). Children's baseline level of PTS symptoms were indexed prior to the medical procedure, and again at 1‐week follow‐up. Immediately after the K‐wire removal, children completed a dot probe task using two categories of target words (medical threatening and emotionally threatening). While K‐wire children showed an overall bias away from negative words relative to healthy controls, the illness group did not significantly differ from healthy controls. Attention bias in K‐wire and illness groups was unrelated to later PTS symptoms.     

Becoming a written word: Eye movements reveal order of acquisition effects following incidental exposure to new words during silent reading

We know that from mid-childhood onwards most new words are learned implicitly via reading; however, most word learning studies have taught novel items explicitly. We examined incidental word learning during reading by focusing on the well-documented finding that words which are acquired early in life are processed more quickly than those acquired later. Novel words were embedded in meaningful sentences and were presented to adult readers early (day 1) or later (day 2) during a five-day exposure phase. At test adults read the novel words in semantically neutral sentences. Participants’ eye movements were monitored throughout exposure and test. Adults also completed a surprise memory test in which they had to match each novel word with its definition. Results showed a decrease in reading times for all novel words over exposure, and significantly longer total reading times at test for early than late novel words. Early-presented novel words were also remembered better in the offline test. Our results show that order of presentation influences processing time early in the course of acquiring a new word, consistent with partial and incremental growth in knowledge occurring as a function of an individual’s experience with each word.     

Saints as the ‘Living Gospel’: Von Balthasar's Revealers of the Revealer,Rahner's Mediators of the Mediator

The theologies of the saints of Hans Urs Von Balthasar and Karl Rahner are grounded in the theologians' distinct articulations of the relationship between nature and grace, Rahner's shaped by his response to the Nouvelle Théologie and Von Balthasar's influenced by his engagement with Henri De Lubac and Karl Barth. It is a generalization, but one useful for drawing contrasts, that for Rahner the saints are mediators of the Mediator and that for Von Balthasar they are revealers of the Revealer. While the theologies can be reconciled, a richer understanding of the function of saints can emerge by maintaining the contrasts. The symbolic capacity of saints in Rahner's thought and the saints' exemplary abandonment to personal mission in Von Balthasar's thought are each an emphasis valuable in communicating saints' instructional and efficacious presence for others in the ecclesial Body.     

An Actor–Partner Interdependence Analysis of Associations between Affect and Parenting Behavior among Couples

Prior studies evaluating associations between parental affect and parenting behavior have typically focused on either mothers or fathers despite evidence suggesting that affect and parenting behavior may be interdependent among couples. This study addressed this gap in the literature by evaluating associations between self‐reported affect and parenting behavior using an actor–partner interdependence analysis among a sample of 53 mother‐father dyads of 3‐ to 5‐year‐old children. Results suggested that mothers' and fathers' negative affect, as well as mothers' and fathers' positive affect, were positively associated. Both mothers' and fathers' negative affect were negatively associated with fathers' positive affect. Mothers' and fathers' harsh/negative parenting behavior, and supportive/engaged parenting behavior, were positively associated. Furthermore, mothers' negative affect was positively associated with mothers' and fathers' harsh/negative parenting behavior while mothers' positive affect was negatively associated with mothers' harsh/negative behavior and positively associated with mothers' supportive/engaged behavior. Fathers' negative affect was positively associated with fathers' supportive/engaged parenting behavior, while fathers' positive affect was positively associated with mothers' and fathers' supportive/engaged behavior. Results highlight the importance of conceptualizing and measuring characteristics of both mothers and fathers, if applicable, when researching the dynamics of interpersonal relationships within families.     

The Pew Versus the Couch: Relationship Between Mental Health and Faith Communities and Lessons Learned from a VA/Clergy Partnership Project

The history of the relationship between religion and mental health is one of commonality, conflict, controversy, and distrust. An awareness of this complex relationship is essential to clinicians and clergy seeking to holistically meet the needs of people in our clinics, our churches, and our communities. Understanding this relationship may be particularly important in rural communities. This paper briefly discusses the history of this relationship and important areas of disagreement and contention. The paper moves beyond theory to present some current practical tensions identified in a brief case study of VA/Clergy partnerships in rural Arkansas. The paper concludes with a framework of three models for understanding how most faith communities perceive mental health and suggests opportunities to overcome the tensions between “the pew” and “the couch.”
