Unimpaired attentional disengagement in toddlers with autism spectrum disorder

A prominent hypothesis holds that ‘sticky’ attention early in life in children with autism spectrum disorder (ASD) limits their ability to explore and learn about the world. Under this hypothesis, the core clinical symptoms of ASD – restricted interests, repetitive behaviors and impaired social/communication abilities – could all result from impaired attentional disengagement during development. However, the existence of disengagement deficits in children with ASD is controversial, and a recent study found no deficit in 5‐ to 12‐year‐olds with ASD. Nonetheless, the possibility remains that disengagement is impaired earlier in development in children with ASD, altering their developmental trajectory even if the attentional deficit itself is remediated or compensated for by the time children with ASD reach school age. Here, we tested this possibility by characterizing attentional disengagement in a group of toddlers just diagnosed with ASD (age 21 to 37 months). We found strikingly similar performance between the ASD and age‐matched typically developing (TD) toddlers, and no evidence of impaired attentional disengagement. These results show that even at a young age when the clinical symptoms of ASD are first emerging, disengagement abilities are intact. Sticky attention is not a fundamental characteristic of ASD, and probably does not play a causal role in its etiology.     

I can time with a little help from my friends: effect of social enrichment on timing processes in Pigeons (<Emphasis Type="Italic">Columba livia</Emphasis>)

There is evidence that impulsive decision-making is associated with errors in timing. However, there has been little attempt to identify the putative mechanism responsible for impulsive animals’ timing errors. One means of manipulating impulsivity in non-human animals is providing different levels of access to conspecifics. These preclinical models have revealed that social isolation increases impulsive responding across a wide range of tasks. The goal of the present study was to determine whether social isolation modulates time perception in pigeons by inducing more variability or a bias to underestimate the passage of time in temporal judgments. A temporal bisection task was used to characterize time perception. One group of pigeons performed the bisection following social enrichment, and the remaining half of the pigeons were tested following social isolation. Results revealed pigeons in the social isolation condition categorized a temporal stimulus sample as “long” at shorter durations than pigeons in the social enrichment condition. These data highlight the mechanism(s) thought to underlie timing-based interventions aimed at reducing impulsivity in humans. Future work should consider whether impulsivity is produced by misperceptions of time or a reduced threshold for a response.     

Group Peer Disagreement

A popular view in mainstream social epistemology maintains that, in the face of a revealed peer disagreement over p, neither party should remain just as confident vis‐a‐vis p as she initially was. This ‘conciliatory’ insight has been defended with regard to individual epistemic peers. However, to the extent that (non‐summativist) groups are candidates for group knowledge and beliefs, we should expect groups (no less than individuals) to be in the market for disagreements. The aim here will be to carve out and explore an extension of the conciliatory insight from individual peer disagreement to group peer disagreement; in doing so, I'll raise and address three key problems that face any plausible defence of such a constraint.     

Race and Nation: How Racial Hierarchy Shapes National Attachments

We contend that the boundaries and nature of national attachments are shaped by the position of one's group within America's racial order, with higher status yielding more racially exclusive forms of identity. We test our claims in the realm of xenophobia. Using an original survey of African Americans (n = 1,000) and Whites (n = 1,000), we assess national pride, nationalism, nativism, and racial identity, plus affect toward various immigrant groups. We establish that national attachments have racially varied meanings, thereby producing sharp differences in each racial group's response to foreigners. Although national pride is unrelated to White antipathy toward outsiders, nationalism and nativism increase White hostility to immigrants—except when they are White. In contrast, national pride diminishes African American hostility to Black and non‐Black immigrants, while nativism is generally unrelated to Black antipathy to outsiders. Finally, while nationalism heightens xenophobia among Blacks, this sentiment envelops all foreigners—including African immigrants. We discuss our results' implications for theories of national attachment in intergroup settings.     

The neural circuitry supporting goal maintenance during cognitive control: a comparison of expectancy AX-CPT and dot probe expectancy paradigms

Goal maintenance is an aspect of cognitive control that has been identified as critical for understanding psychopathology according to criteria of the NIMH-sponsored CNTRICS (Cognitive Neuroscience Treatment Research to Improve Cognition in Schizophrenia) and Research Domain Criteria (RDoC) initiatives. CNTRICS proposed the expectancy AX-CPT, and its visual-spatial parallel the dot probe expectancy (DPX), as valid measures of the cognitive and neural processes thought to be relevant for goal maintenance. The goal of this study was to specifically examine the functional neural correlates and connectivity patterns of both goal maintenance tasks in the same subset of subjects to further validate their neural construct validity and clarify our understanding of the nature and function of the neural circuitry engaged by the tasks. Twenty-six healthy control subjects performed both the letter (AX) and dot pattern (DPX) variants of the CPT during fMRI. Behavioral performance was similar between tasks. The 2 tasks engaged the same brain networks including dorsolateral prefrontal cortex (DLPFC) and dorsal parietal regions, supporting their validity as complementary measures of the goal maintenance construct. Interestingly there was greater engagement of the frontal opercular insula region during the expectancy AX-CPT (letter) and greater functional connectivity between the PFC and medial temporal lobe in the DPX (dot pattern). These differences are consistent with differential recruitment of phonological and visual-spatial processes by the two tasks and suggest that additional long-term memory systems may be engaged by the dot probe version.     

A Comparison of the Nomological Networks Associated With Forced-Choice and Likert Formats of the Narcissistic Personality Inventory

The Narcissistic Personality Inventory (NPI) is one of the most popular measures of narcissism. However, its use of a forced-choice response set might negatively affect some of its psychometric properties. The purpose of this research was to compare a Likert version of the NPI, in which only the narcissistic response of each pair was given, to the original NPI, in 3 samples of participants (N = 1,109). To this end, we compared the nomological networks of the forced-choice and Likert formats of the NPI in relation to alternative measures of narcissism, narcissistic personality disorder, entitlement, self-esteem, general personality traits (reported by self and informants), interpersonal styles, and general pathological traits included in the DSM–5. The Likert format NPI—total and subscales—manifested similar construct validity to the original forced-choice format across all criteria with only minor differences that seem to be due mainly to the increased reliability and variability found in the Likert NPI Entitlement/Exploitativeness subscale. These results provide evidence that a version of the NPI that employs a Likert format can justifiably be used in place of the original.     

Preliminary acceptability and psychometrics of the infant–toddler social and emotional assessment (ITSEA): A new adult-report questionnaire

The preliminary acceptability, internal consistency, test–retest reliability, and validity of the Infant–Toddler Social and Emotional Assessment (ITSEA), a parent-report questionnaire concerning social-emotional problems and competencies, were examined in a sociodemographically diverse pediatric sample of 214 parents of 12- to 36-month-olds. Results supported the ITSEA's acceptability and preliminary internal consistency, test–retest reliability, and validity. Most parents had a positive response to the ITSEA, found the questions easy to understand, and would consider recommending it to a friend. Confirmatory factor analyses supported 16 conceptually hypothesized problem and competence scales. Most scales had strong internal consistency, good to excellent 2-week test–retest reliability, and moderate 1-year test–retest reliability. Significant correlations among ITSEA scales and parent reports of child temperament and problem behaviors supported the ITSEA's validity. Psychometric findings are viewed as preliminary due to the relatively small sample size. Parents reported greater competence and more maladaptive behaviors in older children than younger children. Consistent with observational studies, boys lagged behind girls in certain parent-reported competencies, including empathy, compliance, prosocial peer interactions, and emotional awareness. Parent reports yielded empirically coherent problem and competence scales and domains, suggesting the early emergence of parental perceptions of organized and differentiated clusters of social-emotional behaviors.     

A Narrative Approach to the Clinical Reasoning Process in Pediatric Intensive Care: The Story of Matthew

This paper offers a narrative approach to understanding the process of clinical reasoning in complex cases involving medical uncertainty, moral ambiguity, and futility. We describe a clinical encounter in which the pediatric health care team experienced a great deal of conflict and distrust as a result of an ineffective process of interpretation and communication. We propose a systematic method for analyzing the technical, ethical, behavioral, and existential dimensions of the clinical reasoning process, and introduce the Clinical Reasoning Discussion Tool—a dialogical and interpretive device aimed at improving communication, understanding, empathy, and moral deliberation in the clinical setting.
