Teaching children with autism to follow gaze shift: A brief report on three cases

This study evaluated the extent to which prompting and reinforcement increased three participants' correct selections of items following a therapist's gaze shift using a non‐concurrent multiple baseline design for two participants and an ABCD design for one participant. Results show that each participant learned to discriminate an adult's gaze direction to make a correct selection and each participant's responding generalized to selections with non‐reinforcing stimuli. Two participants also displayed the skill during probe sessions with their parents; however, the third participant required tangible reinforcement for correct selections to demonstrate the skill with a parent.     

Adolescent development of insula‐dependent interoceptive regulation

Adolescence is hypothesized to be a critical period for the maturation of self‐regulatory capacities, including those that depend on interoceptive sensitivity, but the neural basis of interoceptive regulation in adolescence is unknown. We used functional magnetic resonance imaging and psychophysiology to study interoceptive regulation in healthy adolescent females. Participants regulated their gut activities in response to a virtual roller coaster by deep breathing aided by visually monitoring their online electrogastrogram (EGG) activity through a virtual thermometer (i.e. gut biofeedback), or without biofeedback. Analyses focused on the insula, given its putative role in interoception. The bilateral posterior insula showed increased activation in the no‐biofeedback compared to biofeedback condition, suggesting that the participants relied more on interoceptive input when exteroceptive feedback was unavailable. The bilateral dorsal anterior insula showed activation linearly associated with age during both induction and regulation, and its activation during regulation correlated positively with change of EGG in the tachygastria frequency band from induction to regulation. Induction‐related activation in the bilateral ventral anterior insula was nonlinearly associated with age and peaked at mid‐adolescence. These results implicate different developmental trajectories of distinct sub‐regions of the insula in interoceptive processes, with implications for competing neurobiological theories of female adolescent development.     

Challenges for aging Holocaust survivors and their children: The impact of early trauma on aging

ABSTRACT

Is the impact of early trauma continually present or does the negative psychological impact disappear when survivors are younger and then reappear as they age? In Transcending Trauma Project interviews survivors noted the impact of the Holocaust was always present but some stated that it increased as they aged. A small number of children of survivors interviewed observed a dependence upon defense mechanisms to cope with aging which differed from the survivors’ identification of using active and family coping strategies during the war and postwar years. Though children who experienced positive parent-child relationships mentioned the negative coping strategies, they also spoke positively of the impact of their parents in their own lives and expressed empathy for their parents. In the families where tensions existed between the survivors and their children, the children did not express empathy for their aging parents. Several studies supported the importance of family relationships in the aging process. This secondary analysis study further explored the impact of the Holocaust in aging survivors and the views of some children of survivors on aging.     

Not every credible interval is credible: Evaluating robustness in the presence of contamination in Bayesian data analysis

As Bayesian methods become more popular among behavioral scientists, they will inevitably be applied in situations that violate the assumptions underpinning typical models used to guide statistical inference. With this in mind, it is important to know something about how robust Bayesian methods are to the violation of those assumptions. In this paper, we focus on the problem of contaminated data (such as data with outliers or conflicts present), with specific application to the problem of estimating a credible interval for the population mean. We evaluate five Bayesian methods for constructing a credible interval, using toy examples to illustrate the qualitative behavior of different approaches in the presence of contaminants, and an extensive simulation study to quantify the robustness of each method. We find that the “default” normal model used in most Bayesian data analyses is not robust, and that approaches based on the Bayesian bootstrap are only robust in limited circumstances. A simple parametric model based on Tukey’s “contaminated normal model” and a model based on the t-distribution were markedly more robust. However, the contaminated normal model had the added benefit of estimating which data points were discounted as outliers and which were not.     

Reporting of life events over time: methodological issues in a longitudinal sample of women

The number of life events reported by study participants is sensitive to the method of data collection and time intervals under consideration. Individual characteristics also influence reporting; respondents with poor mental health report more life events. Much current research on life events is cross-sectional. Data from a longitudinal study of women's health from 4 waves over a decade suggest that over time additional systematic biases in reporting life events occur. Inconsistency over time is due to both fall-off of reporting and telescoping. Intracategory variability and ambiguity of items, as well as respondent characteristics, also potentially contribute to response biases. Although some factors (e.g., item wording) are controllable, others (e.g., respondents' mental health) are not and must be factored into data analysis and interpretation.     

Rumination and distraction periods immediately following a speech task: effect on postevent processing in social anxiety

The purpose of this study was to investigate social anxiety and the effect of rumination and distraction periods immediately following a speech task on subsequent postevent processing. A secondary aim was to examine the content of postevent rumination. Participants (N = 114 students) completed measures of social anxiety and depression, delivered a 3-minute speech, and were randomly assigned to complete (1) a rumination form about the speech (guided negative rumination condition) or (2) an anagram form (distraction condition). One week later participants completed measures of postevent processing related to the speech task. It was hypothesized that social anxiety would interact with condition in predicting levels of postevent processing. This hypothesis was supported in the prediction of positive thoughts such that at high levels of social anxiety the distraction condition led to more positive thoughts compared with the guided negative rumination condition, whereas at low levels of social anxiety conditions were similar with respect to positive thoughts. Irrespective of condition, both social anxiety and depression predicted greater postevent rumination and negative thoughts 1 week later. With respect to the content of postevent rumination, socially anxious individuals reported being more concerned about some aspects of the presentation (e.g. poor posture), whereas other concerns were equally noted regardless of social anxiety level (e.g. poor content). The present results highlight the potential clinical utility of distracting from social anxiety to allow for greater access to positive thoughts postevent.     

The non-Christian influence on Anselm’s <Emphasis Type="Italic">Proslogion</Emphasis> argument

This paper considers Anselm’s Proslogion argument against a background of historical events that include philosophical disputes between Christian and Jewish polemicists. I argue that the Proslogion argument was addressed, in part, to non-Christian theists and that it offered a response to Jewish polemicists who had argued that the Christian conception of God as an instantiated unity was irrational. Anselm is not trying to convince atheists that there really is a God. He is arguing that the Christian conception of God is logically coherent.     

Measuring and reducing college students' procrastination

We examined college students' procrastination when studying for weekly in-class quizzes. Two schedules of online practice quiz delivery were compared using a multiple baseline design. When online study material was made available noncontingently, students usually procrastinated. When access to additional study material was contingent on completing previous study material, studying was more evenly distributed. Overall, the mean gain in percentage correct scores on weekly in-class quizzes relative to pretests was greater during contingent access than during noncontingent access conditions.
