Combining video modeling and least‐to‐most prompting for establishing response chains

Video modeling combined with least‐to‐most intrusive prompting was compared using a parallel‐treatments design to least‐to‐most intrusive prompting alone in teaching daily‐living skills in the form of response chains. Two boys with the diagnosis of autism (ages 8 and 9) participated in the study. The results showed that the participants acquired skills taught with video modeling plus least‐to‐most prompting in fewer trials and with fewer prompts than skills taught with least‐to‐most prompting alone.

Effort during visual search and counting: insights from pupillometry

We investigated the processing effort during visual search and counting tasks using a pupil dilation measure. Search difficulty was manipulated by varying the number of distractors as well as the heterogeneity of the distractors. More difficult visual search resulted in more pupil dilation than did less difficult search. These results confirm a link between effort and increased pupil dilation. The pupil dilated more during the counting task than during target-absent search, even though the displays were identical, and the two tasks were matched for reaction time. The moment-to-moment dilation pattern during search suggests little effort in the early stages, but increasingly more effort towards response, whereas the counting task involved an increased initial effort, which was sustained throughout the trial. These patterns can be interpreted in terms of the differential memory load for item locations in each task. In an additional experiment, increasing the spatial memory requirements of the search evoked a corresponding increase in pupil dilation.These results support the view that search tasks involve some, but limited, memory for item locations, and the effort associated with this memory load increases during the trials. In contrast, counting involves a heavy locational memory component from the start.

Community Power Structure Analysis and the Ethical Considerations of “Studying Up”

This narrative outlines our challenges in studying power and power structures within an individual‐level ethical framework. Taking a social ethics perspective, we share the story of our “sticky situation” (Campbell, 2016 ) that transpired during a multi‐year community partnership. We were asked, by our community partners, to help collect interview data without informed consent. As a team of community‐engaged university researchers, we were faced with a seemingly easy ethical situation (no consent, no research) that had unexpectedly complicated and long‐lasting consequences. This experience revealed to us how community‐engaged research and action, under a traditional ethics framework, can often work to protect those in positions of power and offer little to disrupt the status quo. Reflecting on the tension between individual and social ethics, we discuss the limitations of an individual‐level framework, including the definitions for respect for persons, justice, and beneficence, on our ability as a field to understand, critique, and contribute to the dismantling of oppressive power structures.     

Predicting sugar-sweetened behaviours with theory of planned behaviour constructs: Outcome and process results from the SIPsmartER behavioural intervention

Objective: Guided by the theory of planned behaviour (TPB) and health literacy concepts, SIPsmartER is a six-month multicomponent intervention effective at improving SSB behaviours. Using SIPsmartER data, this study explores prediction of SSB behavioural intention (BI) and behaviour from TPB constructs using: (1) cross-sectional and prospective models and (2) 11 single-item assessments from interactive voice response (IVR) technology.

Design: Quasi-experimental design, including pre- and post-outcome data and repeated-measures process data of 155 intervention participants.

Main Outcome Measures: Validated multi-item TPB measures, single-item TPB measures, and self-reported SSB behaviours. Hypothesised relationships were investigated using correlation and multiple regression models.

Results: TPB constructs explained 32% of the variance cross sectionally and 20% prospectively in BI; and explained 13–20% of variance cross sectionally and 6% prospectively. Single-item scale models were significant, yet explained less variance. All IVR models predicting BI (average 21%, range 6–38%) and behaviour (average 30%, range 6–55%) were significant.

Conclusion: Findings are interpreted in the context of other cross-sectional, prospective and experimental TPB health and dietary studies. Findings advance experimental application of the TPB, including understanding constructs at outcome and process time points and applying theory in all intervention development, implementation and evaluation phases.     

Personal and Intergenerational Narratives of Transgression and Pride in Emerging Adulthood: Links to Gender and Well‐Being

Intergenerational narratives, stories parents share with children about their own youthful experiences, may facilitate the understanding of challenging life experiences and be related to psychological well‐being; yet, little research has examined what young people know of their parents' self‐challenging and self‐enhancing experiences and how they interpret them. Research examining intergenerational narratives has observed relations between adolescents' narratives and their psychological well‐being, but these relations may depend upon gender and narrative type. In the current study, 94 college students provided intergenerational and personal narratives of transgression and pride experiences. Narratives were coded for emotional, cognitive, and evaluative content. Results show that transgression and pride narratives differed in content, and that women provided more interpretative content than men. Stories about mothers contained more interpretative content than fathers, but this pattern varied by participant gender. Finally, relations to well‐being were observed, especially for cognitive content in stories of participants' same‐gender parent.

Deconstructing the Time-Out: What Do Mothers Understand About a Common Disciplinary Procedure?

Time-out (TO) is one of the most common and effective disciplinary tactics used to address problem behavior; however, parents rate TO as one of the least useful behavior modification techniques. This may be due to a discrepancy between empirically supported TO procedures and how mothers are actually conducting TO. Fifty-five mothers were asked to define TO, provide information on how they conduct TO, and identify errors in TO procedures. Results indicate that maternal knowledge and implementation of TO differs considerably from the empirical ideal, potentially impacting the utility and frequency of TO usage in the home to address child problem behaviors.     

Low Maternal Warmth Mediates the Relationship Between Emotional Neglect and Callous-Unemotional Traits Among Male Juvenile Offenders

Callous-unemotional traits (CU) are thought to be the developmental precursor to adult psychopathy, and identify antisocial youth at risk for persistent, aggressive conduct problems. Accumulating research supports the importance of parenting factors in the development of CU traits. The overlapping but distinct constructs, parental neglect and low warmth, are both associated with CU/psychopathic traits; however, research is yet to examine the relative contribution of these constructs. The purpose of the present study was to examine the unique contributions of parental neglect and low warmth to CU traits among 227 incarcerated male juvenile offenders (M?=?15.73, SD?=?1.27 years). Results indicated that low levels of maternal warmth were more strongly associated with CU traits than emotional and physical neglect. Maternal warmth also significantly mediated the association between emotional neglect and CU traits. Findings from this cross-sectional study suggest that parental neglect influences CU traits at least partly through experiences with unresponsive and emotionally “cold” parenting. The findings also support a movement within the field towards addressing parental warmth as a treatment target for antisocial youth with CU traits.
