The rooting reflex as an infant feeding cue

Experts in infant health and development consider the rooting reflex a cue of a baby's hunger and recommend feeding the infant when this reflex occurs. However, the relation between rooting and infant feeding status has not been well established in the literature. In the current study, seven parents documented the occurrence of their newborns' rooting, crying, and a control reflex (palmar grasp) before, after, and between naturally occurring feedings. For all participants, rooting occurred during a greater percentage of reflex checks prior to feedings, whereas the palmar grasp occurred during a similar percentage of checks across these time periods. These results provide empirical support for the rooting reflex as a feeding cue. However, data for only one dyad suggested a high probability of the rooting reflex occurring without crying during prefeeding checks. Thus, our data do not provide evidence that feeding in response to the rooting reflex would preempt infant crying.     

Learning from a failure in threat assessment: 11 questions and not enough answers

Threat assessment theory and practice have evolved significantly since Columbine. The US Secret Service's guidelines for threat assessment include 11 questions that school officials should ask to identify, investigate, and manage students of concern. Yet, no research examines how school officials implement these questions. This qualitative case study examines the way that school officials used the 11 questions with a student of concern, who underwent a threat assessment and 3 months later shot and killed a classmate and himself on school grounds. The data include deposition testimony from 12 school and district officials and more than 8,000 pages of records in the case. For each of the 11 questions, the findings reveal what the threat assessment team knew and might have learned; the findings also demonstrate the importance of multiple sources of information, a multidisciplinary team, and an investigative mindset. The questions may prove difficult to answer in “loosely coupled” systems, like schools, where information is unintentionally lost due to the organization's structural hierarchy, specialization of tasks, and heavy workloads. The findings provide critical lessons learned for threat assessment, information gathering, and violence prevention in schools.     

Understanding Variations in Judgments of Infidelity: An Application of Attribution Theory

The current program of research examined how the four dimensions of the attribution (locus of causality, controllability, stability, intentionality) influenced judgments of a partner’s hypothetical infidelity and actor-observer discrepancies associated with judgments of real-life infidelity. The results from Study 1 (N?=?396) revealed that the dimensions of the attribution affected the extent to which adults’ judged a partner’s hypothetical behavior as indicative of infidelity differently depending on the type of behavior. When reporting on real-life behavior (Study 2, N?=?802), adults attributed the cause of their partner’s infidelity as being a result of internal, controllable, stable, and intentional causes to a greater extent than when judging their own infidelity.     

Hot and Cool Executive Function and its Relation to Theory of Mind in Children with and without Autism Spectrum Disorder

Previous research has clearly demonstrated that autism spectrum disorder (ASD) involves deficits in multiple neuropsychological functions, such as executive function (EF) and theory of mind (ToM). A conceptual distinction is commonly made between cool and hot EF. In ASD, continued attention has been paid to the cool areas of executive dysfunction. Cool EF has been strongly related to ToM, but research has not taken into account the association between hot EF and ToM in ASD. The present study investigated the associations between hot and cool EF and ToM in 56 school-aged children with ASD and 69 controls on tasks tapping cool EF (i.e., working memory, inhibition, planning), hot EF (i.e., affective decision making, delay discounting), and ToM (i.e., mental state/emotion recognition and false belief). Significant group differences in each EF measure support an executive dysfunction in both domains in ASD. Strong associations between delay discounting and ToM mental state/emotion recognition were found, suggesting that hot EF makes a unique contribution to ToM above and beyond cool EF in typical development and ASD. This study improves understanding of the profile of higher-order cognitive deficits in children with ASD, which may inform diagnosis and intervention.     

A Story Does Exist: A Qualitative Exploration of the Use of Reflective Stories in Pre-Practicum

The authors explored the lived experiences of two cohorts of counselors-in-training who experienced a metaphoric story creation activity in pre-practicum II, a clinical training course. Using Merriam’s interpretive qualitative approach, the data suggested that students perceived the activity to have facilitated their ability to make meaning of their experiences in the class, as well as to better understand their development as counselors-in-training.     

Costs and benefits of representational change: effects of context on age and sex differences in symbolic magnitude estimation

Studies have reported high correlations in accuracy across estimation contexts, robust transfer of estimation training to novel numerical contexts, and adults drawing mistaken analogies between numerical and fractional values. We hypothesized that these disparate findings may reflect the benefits and costs of learning linear representations of numerical magnitude. Specifically, children learn that their default logarithmic representations are inappropriate for many numerical tasks, leading them to adopt more appropriate linear representations despite linear representations being inappropriate for estimating fractional magnitude. In Experiment 1, this hypothesis accurately predicted a developmental shift from logarithmic to linear estimates of numerical magnitude and a negative correlation between accuracy of numerical and fractional magnitude estimates (r = −.80). In Experiment 2, training that improved numerical estimates also led to poorer fractional magnitude estimates. Finally, both before and after training that eliminated age differences in estimation accuracy, complementary sex differences were observed across the two estimation contexts.     

Teaching preschool children to avoid poison hazards

We evaluated the effectiveness of group safety training and in situ feedback and response interruption to teach preschool children to avoid consuming potentially hazardous substances. Three children ingested ambiguous substances during a baited baseline assessment condition and continued to ingest these substances following group safety training. In situ feedback and response interruption resulted in a decrease in opening ambiguous containers; this decrease was maintained when ambiguous novel containers were presented and when assessments occurred in a novel setting and with a novel experimenter. For 2 children, these gains were also maintained during a brief follow-up period. Twelve children did not ingest ambiguous substances prior to training, and group safety training did not evoke inappropriate ingestion.     

Grades of meaning

In this paper, I lend novel support to H. P. Grice’s account of speaker meaning (GASM) by blunting the force of a significant objection. Stephen Schiffer has argued that in order to make GASM sufficient, one must add restrictions that are psychologically impossible to fulfill, thereby making GASM untenable. In what follows, I explain the elements of GASM that require it to invoke these psychologically unrealizable restrictions. I then accept Schiffer’s criticism, but modify its significance to GASM. I argue that the problem that Schiffer notes is not a reason to reject GASM, but a reason to embrace it. GASM shows that meaning is best understood as an absolute concept—an unrealizable ideal limit. Taking some inspiration from contextualist theories of knowledge attribution, I argue that my version of GASM offers a useful contextualist account of meaning attribution. Hence, pragmatic theories of meaning and communication should not wholly exclude GASM from their theorizing, at least not for the reasons that are commonly given.     

Inspecting visual mental images: Can people “see” implicit properties as easily in imagery and perception?

Can people “see” previously unnoticed properties in objects that they visualize, or are they locked into the organization of the pattern that was encoded during perception? To answer this question, we first asked a group to describe letters of the alphabet and found that some properties (such as the presence of a diagonal line) are often mentioned, whereas others (such as symmetry) are rarely if ever mentioned. Then we showed not only that other participants could correctly detect both kinds of properties in visualized letters, but also that the relative differences in the ease of detecting these two types of properties are highly similar in perception (when the letters are actually visible) and imagery (when the letters are merely visualized). These findings provide support for the view that images can be reinterpreted in ways much like what occurs during perception and speak to the wider issue of the long-standing debate about the format of mental images.
