Treating food selectivity as resistance to change in children with autism spectrum disorder

Change-resistant behavior, such as rigid and selective food consumption, is a core symptom of autism that can have significant negative consequences for the child (Flygare Wallén et al., 2018; Levy et al., 2019). In the current study, we used a matching-law-based intervention (Fisher et al., 2019) to treat the change-resistant feeding behavior of 7 young children with autism. The feeder gave the participant a choice between a change-resistant and an alternative food during free- and asymmetrical-choice conditions. Alternative-food consumption increased for 2 participants during asymmetrical choice when the feeder provided a preferred item for consuming the alternative food and no programmed consequence for consuming the change-resistant food. Alternative-food consumption increased for the other 5 participants after the feeder exposed at least 1 food to single choice in which the feeder guided the participant to put the bite of alternative food in his or her mouth if he or she did not do so within 8 s of presentation. Effects of the single-choice contingencies maintained during reversals and generalized to other alternative foods the feeder did not expose to single choice. These results are important because participants consumed alternative foods even when their change-resistant foods were present, which is similar to typical mealtime contexts in which children have choices among foods.     

The Epidemiology of Homicide followed by Suicide: A Systematic and Quantitative Review

This systematic review of population based studies of homicide followed by suicide was conducted to examine the associations between rates of homicide‐suicide, rates of other homicides and rates of suicide. The review analysed 64 samples, including the case of an outlier (Greenland) that were reported in 49 studies. There was a significant association between the rates of homicide‐suicide and those of other homicides in studies from the U.S.A. Outside the U.S.A. there was no clear association between homicide‐suicide and other homicide but there was modest but significant association between rates of suicide and homicide‐suicide. Homicide‐suicide appears to be closer in epidemiological terms to homicide than suicide in regions with high rates of homicide and measures to reduce homicide in these regions may also reduce homicide‐suicide.     

Categorical perception of tactile distance

The tactile surface forms a continuous sheet covering the body. And yet, the perceived distance between two touches varies across stimulation sites. Perceived tactile distance is larger when stimuli cross over the wrist, compared to when both fall on either the hand or the forearm. This effect could reflect a categorical distortion of tactile space across body-part boundaries (in which stimuli crossing the wrist boundary are perceptually elongated) or may simply reflect a localised increased in acuity surrounding anatomical landmarks (in which stimuli near the wrist are perceptually elongated). We tested these two interpretations across two experiments, by comparing a well-documented bias to perceive mediolateral tactile distances across the forearm/hand as larger than proximodistal ones along the forearm/hand at three different sites (hand, wrist, and forearm). According to the ‘categorical’ interpretation, tactile distances should be elongated selectively in the proximodistal axis thus reducing the anisotropy. According to the ‘localised acuity’ interpretation, distances will be perceptually elongated in the vicinity of the wrist regardless of orientation, leading to increased overall size without affecting anisotropy. Consistent with the categorical account, we found a reduction in the magnitude of anisotropy at the wrist, with no evidence of a corresponding localised increase in precision. These findings demonstrate that we reference touch to a representation of the body that is categorically segmented into discrete parts, which consequently influences the perception of tactile distance.     

Beyond Deep Incarnation: Rethinking Christology in Radical Lutheran Terms

This article takes the demise of Christendom and what Diana Butler Bass calls the end of religion as its point of departure for a “radical” rethinking of God in fully kenotic terms. It rejects any vestige of otherworldly transcendence as a temptation to escapism, inviting us instead to seek God's complete presence among us here in the world. Going beyond Niels Gregersen's understanding of the deep incarnation of the Logos and starting instead with a complete commitment to the infra‐Lutheranum, the author presents a radical Lutheran theology that embraces a total kenosis of God whose liberating and life‐giving reappearance we must find implicit among us in unexpected places, not least of which might include the embers of a dying church or the crumbling of our religious institutions.     

Guilty,But Not Ashamed: “True” Self‐Conceptions Influence Affective Responses to Personal Shortcomings

The current research examined how true self‐conceptions (who a person believes he or she truly is) influence negative self‐relevant emotions in response to shortcomings. In Study 1 (N = 83), an Internet sample of adults completed a measure of authenticity, reflected on a shortcoming or positive life event, and completed state shame and guilt measures. In Study 2 (N = 49), undergraduates focused on true versus other determined self‐attributes, received negative performance feedback, and completed state shame and guilt measures. In Study 3 (N = 138), undergraduates focused on self‐determined versus other determined self‐aspects, reflected on a shortcoming or neutral event, and completed state shame, guilt, and self‐esteem measures. In Study 4 (N = 75), undergraduates thought about true self‐attributes, an achievement, or an ordinary event; received positive or negative performance feedback; and completed state shame and guilt measures. In Study 1, differences in true self‐expression positively predicted shame‐free guilt (but not guilt‐free shame) following reminders of a shortcoming. Studies 2–4 found that experimental activation of true self‐conceptions increased shame‐free guilt and generally decreased guilt‐free shame in response to negative evaluative experiences. The findings offer novel insights into true self‐conceptions by revealing their impact on negative self‐conscious emotions.     

Openness to Experience,Intellect, and Cognitive Ability

An instrument designed to separate 2 midlevel traits within each of the Big Five (the Big Five Aspect Scales [BFAS]) was used to clarify the relation of personality to cognitive ability. The BFAS measures Openness to Experience and Intellect as separate (although related) traits, and refers to the broader Big Five trait as Openness/Intellect. In 2 samples (N = 125 and 189), Intellect was independently associated with general intelligence (g) and with verbal and nonverbal intelligence about equally. Openness was independently associated only with verbal intelligence. Implications of these findings are discussed for the empirical and conceptual relations of intelligence to personality and for the mechanisms potentially underlying both Openness/Intellect and cognitive ability.
