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.     

WONDER OPENS THE HEART: POPE FRANCIS AND LISA SIDERIS ON NATURE,ENCOUNTER, AND WONDER

This article argues that Pope Francis's invocations of wonder can speak to and at times challenge Lisa Sideris's recent contributions to the interdisciplinary discussion of wonder, science, and religion. Although the importance of wonder to Pope Francis's 2015 environmental encyclical Laudato si’ is acknowledged, it has not been widely recognized that wonder is implicated in and forms connections between multiple concepts and postures acknowledged as defining marks of Francis's papacy: coming out of oneself, encountering others, going to the margins; aversion to doctrinal rigidity; compassion, mercy, tenderness, and humility; to name a few. These defining concepts and stances resonate strongly with certain views on wonder, ethics, and ecology recently articulated by Lisa Sideris. In Francis, however, one finds a more affirming treatment of science‐based wonder and a response to Sideris's criticism of theistic wonder.     

A Review of Measures of Erikson’s Stages of Psychosocial Development: Evidence for a General Factor

Recent research suggests that values on Erikson’s psychosocial stages covary to form a general factor of psychosocial development (GFPD). The purpose of the current investigation was to further test this possibility by conducting a meta-analysis on the association among the psychosocial stages. Sixty-two correlation matrices from 50 different samples (N = 20,326) were analyzed. Factor analyses supported the existence of a GFPD. Future research should explore the nature of the GFPD.     

A Positive Perspective on Attentional Bias: Positive Affectivity and Attentional Bias to Positive Information

In recent years there has been growing interest in determining the attentional basis of positive affectivity. Investigators have sought to evaluate the hypothesis that elevated positive affectivity is characterized by an attentional bias that favours the processing of positive information over neutral information. Unfortunately, in the studies carried out to date, the assessment procedures used by researchers to assess such attentional selectivity have either been methodologically limited or methodologically flawed. Hence, the validity of the hypothesis has remained indeterminate. To overcome the problems associated with attentional assessment procedures used in previous studies, and so shed light on the attentional basis of positive affectivity, we employed an appropriate variant of the attentional probe task. Our findings show that participants high in positive affectivity displayed greater relative attention to positive information compared to neutral information, than was the case for their low positive affectivity counterparts. Thus, the present results support the hypothesis that an attentional bias to positive information, relative to neutral information, is characteristic of elevated positive affectivity.     

Trait compassion is associated with the neural substrate of empathy

Individual differences in the personality trait Agreeableness underlie humans’ ability to interpret social cues and coordinate effectively with others. However, previous investigations of the neural basis of Agreeableness have yielded largely inconsistent results. Recent evidence has demonstrated that Agreeableness can be divided into two, correlated subdimensions. Compassion reflects tendencies toward empathy, sympathy, and concern for others, while Politeness reflects tendencies toward compliance and refraining from aggression and exploitation. The present study seeks to clarify the neural substrates of Agreeableness by examining whether structural differences in the brain show distinct associations with Compassion and Politeness. Results of a meta-analysis of fMRI studies examining empathy were used to generate hypotheses about the brain regions and networks that underlie trait Compassion. Results of a large-scale structural neuroimaging investigation (N = 275) were largely consistent with the meta-analysis: Compassion was positively correlated with gray matter volume in the bilateral anterior cingulate cortex (ACC) and anterior insula (AI). Further, these differences appear to be associated with Compassion specifically, as opposed to Politeness, suggesting that these two traits have at least partially distinct neuroanatomical substrates.     

Binding object features to locations: Does the “spatial congruency bias” update with object movement?

One of the fundamental challenges of visual cognition is how our visual systems combine information about an object’s features with its spatial location. A recent phenomenon related to object–location binding, the “spatial congruency bias,” revealed that two objects are more likely to be perceived as having the same identity or features if they appear in the same spatial location, versus if the second object appears in a different location. The spatial congruency bias suggests that irrelevant location information is automatically encoded with and bound to other object properties, biasing perceptual judgments. Here we further explored this new phenomenon and its role in object–location binding by asking what happens when an object moves to a new location: Is the spatial congruency bias sensitive to spatiotemporal contiguity cues, or does it remain linked to the original object location? Across four experiments, we found that the spatial congruency bias remained strongly linked to the original object location. However, under certain circumstances—for instance, when the first object paused and remained visible for a brief time after the movement—the congruency bias was found at both the original location and the updated location. These data suggest that the spatial congruency bias is based more on low-level visual information than on spatiotemporal contiguity cues, and reflects a type of object–location binding that is primarily tied to the original object location and that may only update to the object’s new location if there is time for the features to be re-encoded and rebound following the movement.     

Eating together apart: patterns of segregation in a multi‐ethnic cafeteria

Research on segregation has tended to focus on relations located at a macro‐spatial level of analysis and unfolding in contexts where boundaries to interaction are formally established. This research, by contrast, investigated segregation as a micro‐ecological process by observing patterns of seating in a multi‐ethnic cafeteria. A total of 3114 seating positions were coded over a 2‐week period and the resulting data were analysed using both adapted segregation indices (P and D) and loglinear and logistic regression techniques. The results suggested that ethnic segregation existed both at the level of interactional groups and in the form of broader patterns of racial clustering and dispersal in the cafeteria. Moreover, the magnitude of segregation was predicted by the gender composition of seating groups and by variations in the density of the cafeteria's population over time. Some implications of these results for social psychological research on contact and desegregation are considered. Copyright © 2004 John Wiley & Sons, Ltd.
