A comparison of functional analysis methods of inappropriate mealtime behavior

Investigators have evaluated two procedural variations for conducting a functional analysis of inappropriate mealtime behavior exhibited by children with feeding problems. One method involves prompting bites only in the escape condition (e.g., Najdowski et al., 2008). Another method involves prompting bites across all conditions (e.g., Piazza et al., 2003). We assessed the food refusal of 3 children diagnosed with a feeding disorder by comparing the two variations. The two methods resulted in different outcomes for 2 of 3 children. Prompting bites only in the escape condition identified a single function (i.e., escape). Prompting bites across all conditions identified multiple functions (i.e., escape and attention). We then examined the relative effects of extinction procedures (individually and in combination) to determine the validity of each method. Results of the treatment evaluation suggested that the procedural variation that failed to identify an attention function for 2 of 3 children produced false negative findings.     

Noncontingent and differential reinforcement in the treatment of pediatric feeding problems

We conducted functional analyses of the inappropriate mealtime behavior of 5 children diagnosed with feeding problems. Then, we compared the effects of differential and noncontingent reinforcement, and the relative effects of escape extinction with and without differential or noncontingent reinforcement, when escape extinction appeared necessary. Both reinforcement procedures were effective without escape extinction to treat food refusal for 1 child, but only differential reinforcement was effective without escape extinction to treat the child's liquid refusal. Escape extinction was necessary for 4 of 5 children. The addition of positive reinforcement resulted in beneficial effects (i.e., more stable acceptance, decreased inappropriate mealtime behavior or negative vocalizations) with 3 of 4 children. With escape extinction, differential reinforcement was more effective to treat food refusal for 2 children and noncontingent reinforcement was more effective for 1 child.     

Associations of Emotional Abuse Types With Suicide Ideation Among Dating Couples

Numerous studies have demonstrated that coercive control is more strongly associated with suicidal ideation than other forms of intimate partner violence. However, a majority of these studies focused on samples of help-seeking women. This study examined whether coercive control remains the form of intimate partner violence most strongly associated with suicidal ideation within a sample of nonclinical dating couples. This cross-sectional, survey study on 104 dating couples examined the associations of coercive control (i.e., dominance/intimidation and restrictive engulfment) with suicidal ideation, while controlling for other forms of emotional abuse (i.e., hostile withdrawal and denigration), physical assault, and depressive symptoms. As expected, dominance/intimidation and depressive symptoms, but not denigration and physical assault, were associated with suicidal ideation. Contrary to our hypothesis, hostile withdrawal, but not restrictive engulfment, was associated with suicidal ideation. This study suggests that dominance/intimidation and hostile withdrawal are forms of emotional abuse that are pertinent to suicidal ideation in nonclinical dating couples.     

The explanatory structure of unexplainable events: Causal constraints on magical reasoning

A common intuition, often captured in fiction, is that some impossible events (e.g., levitating a stone) are “more impossible” than others (e.g., levitating a feather). We investigated the source of this intuition, hypothesizing that graded notions of impossibility arise from explanatory considerations logically precluded by the violation at hand but still taken into account. Studies 1–4 involved college undergraduates (n = 357), and Study 5 involved preschool-aged children (n = 32). In Studies 1 and 2, participants saw pairs of magical spells that violated one of 18 causal principles—six physical, six biological, and six psychological—and were asked to indicate which spell would be more difficult to learn. Both spells violated the same causal principle but differed in their relation to a subsidiary principle. Participants’ judgments of spell difficulty honored the subsidiary principle, even when participants were given the option of judging the two spells equally difficult. Study 3 replicated those effects with Likert-type ratings; Study 4 replicated them in an open-ended version of the task in which participants generated their own causal violations; and Study 5 replicated them with children. Taken together, these findings suggest that events that defy causal explanation are interpreted in terms of explanatory considerations that hold in the absence of such violations.

Linking Workplace Aggression to Employee Well-Being and Work: The Moderating Role of Family-Supportive Supervisor Behaviors (FSSB)

Purpose

The present study examined the moderating effects of family-supportive supervisor behaviors (FSSB) on the relationship between two types of workplace aggression (i.e., patient-initiated physical aggression and coworker-initiated psychological aggression) and employee well-being and work outcomes.

Methodology

Data were obtained from a field sample of 417 healthcare workers in two psychiatric hospitals. Hypotheses were tested using moderated multiple regression analyses.

Findings

Psychiatric care providers’ perceptions of FSSB moderated the relationship between patient-initiated physical aggression and physical symptoms, exhaustion and cynicism. In addition, FSSB moderated the relationship between coworker-initiated psychological aggression and physical symptoms and turnover intentions.

Implications

Based on our findings, family-supportive supervision is a plausible boundary condition for the relationship between workplace aggression and well-being and work outcomes. This study suggests that, in addition to directly addressing aggression prevention and reduction, family-supportive supervision is a trainable resource that healthcare organizations should facilitate to improve employee work and well-being in settings with high workplace aggression.

Originality

This is the first study to examine the role of FSSB in influencing the relationship between two forms of workplace aggression: patient-initiated physical and coworker-initiated psychological aggression and employee outcomes.

     

Executive functioning and prospective memory in young children

The current study examined the role of executive functioning (EF) in children's prospective memory (PM) by assessing the effect of delay and number of intentions to-be-remembered on PM, as well as relations between PM and EF. Ninety-six 4-, 5-, and 6-year-olds completed a PM task and two executive function tasks. The PM task required children to interrupt an ongoing card game to perform one action (single intention) or two actions (dual intention) with target cards after a short delay (1 min) or a long delay (5 min). There was no main effect of number of intentions or delay on the PM task. However, performance improved with age, and age and delay interacted such that 4-year-olds’ performance remained the same after a long delay whereas 5-year-olds’ performance improved after a long delay. We suggest that the age by delay interaction is a product of age differences in cognitive monitoring. Working memory but not inhibitory control predicted PM with age controlled. We argue that an executive function framework permits an integrative understanding of many processes involved in young children's prospective memory.     

Endocannabinoids and stress

Endogenous cannabinoids play an important role in the physiology and behavioral expression of stress responses. Activation of the hypothalamic-pituitary-adrenal (HPA) axis, including the release of glucocorticoids, is the fundamental hormonal response to stress. Endocannabinoid (eCB) signaling serves to maintain HPA-axis homeostasis, by buffering basal activity as well as by mediating glucocorticoid fast feedback mechanisms. Following chronic stressor exposure, eCBs are also involved in physiological and behavioral habituation processes. Behavioral consequences of stress include fear and stress-induced anxiety as well as memory formation in the context of stress, involving contextual fear conditioning and inhibitory avoidance learning. Chronic stress can also lead to depression-like symptoms. Prominent in these behavioral stress responses is the interaction between eCBs and the HPA-axis. Future directions may differentiate among eCB signaling within various brain structures/neuronal subpopulations as well as between the distinct roles of the endogenous cannabinoid ligands. Investigation into the role of the eCB system in allostatic states and recovery processes may give insight into possible therapeutic manipulations of the system in treating chronic stress-related conditions in humans.
