Tap,swipe, and build: Parental spatial input during iPad® and toy play

Despite the increase in the use of interactive technological devices, little is known about the impact that play context has on the production of spatial language by parents. To investigate whether there is differential parental spatial input afforded by play contexts with their preschoolers, 34 children (20 girls, 14 boys) and their primary caregivers engaged in 30‐min 3‐dimensional (3D) spatial play using blocks and puzzles and virtual 2‐dimensional (2D) spatial play using an iPad^® in 2 separate home visits. There were no significant differences in the average amount of spatial talk and the number of spatial categories used by parents in both 3D and 2D play contexts. However, the amount of parental spatial talk decreased significantly with older preschoolers using the iPad^®. In the 3D play contexts, parents produced more words related to spatial dimensions, location and directions, and continuous amount than in the 2D play contexts. However, in the 2D play contexts, they produced more words associated with orientations and transformations as well as deictics than in the 3D play contexts. Our findings suggest that technology can be effectively introduced into play contexts to elicit enriched parental spatial input by supporting parents and caregivers with best practices.

Highlights

• The present study examines the differences in parental spatial talk when using traditional versus technology‐based learning tools with their preschoolers.
• Two 30‐min home observations of parent–child dyads playing blocks and puzzles versus spatial apps on an iPad^®. No significant differences in the amount of parental spatial talk and the number of spatial categories in both play contexts were found.
• Our findings suggest that technology can be effectively introduced into play contexts to elicit enriched parental spatial input.

     

A case-controlled field study evaluating ICD-11 proposals for relational problems and intimate partner violence

Background/Objective: Intimate partner relationship problems and intimate partner abuse and neglect — referred to in this paper as “relational problems and maltreatment” — have substantial and well-documented impact on both physical and mental health. However, classification guidelines, such as those found in the International Classification of Diseases (ICD-10), are vague and unlikely to support consistent application. Revised guidelines proposed for ICD-11 are much more operationalized. We used standardized clinical vignette conditions with an international panel of clinicians to test if ICD-11 changes resulted in improved classification accuracy. Method: English-speaking mental health professionals (N = 738) from 65 nations applied ICD-10 or ICD-11 (proposed) guidelines with experimentally manipulated case presentations of presence or absence of (a) individual mental health diagnoses and (b) relational problems or maltreatment. Results: ICD-11, compared with ICD-10, guidelines resulted in significantly better classification accuracy, although only in the presence of co-morbid mental health problems. Clinician factors (e. g., gender, language, world region) largely did not impact classification performance. Conclusions: Despite being considerably more explicated, raters’ performance with ICD-11 guidelines reveals training issues that should be addressed prior to the release of ICD-11 in 2018 (e. g., overriding the guidelines with pre-existing archetypes for relationship problems and physical and psychological abuse).     

A Place for Individual Differences in What Everyone Knows About What Everyone Does: Positive Affect,Cognitive Processes,and Cognitive Experiential Self Theory

Individual differences are often incorporated into experimental research to elucidate inconsistent effects. We argue that the inclusion of such differences into established and seemingly straightforward findings is imperative to the goal of reaching a more complete understanding about the processes of interest. Drawing on research on the cognitive effects of positive affect, we illustrate how integrating individual differences in cognitive processing styles to this literature might lead to a more nuanced understanding of the impact of affect on cognitive processes. The addition of individual differences to psychological research should be seen as a means to a thorough scientific comprehension of a topic rather than as burdensome caveats to otherwise straightforward findings.     

Harm, intent, and the nature of aggressive behavior: measuring naturally occurring aggression in barroom settings

The research goals were to use the constructs of harm and intent to quantify the severity of aggression in the real-world setting of the bar/club, to describe the range of aggressive behaviors and their relationship to harm and intent, and to examine gender differences in the form and severity of aggression. Systematic observations were conducted by trained observers on 1,334 nights in 118 bars/clubs. Observers documented a range of aggressive acts by 1,754 patrons in 1,052 incidents, with many forms of aggression occurring at more than one harm and intent level. Women used different forms of aggression, inflicted less harm, and were more likely to have defensive intent compared with men. Implications of the findings for research and measurement of aggression and applications to preventing aggression and violence are discussed.     

Detecting true lies: police officers' ability to detect suspects' lies

Ninety-nine police officers, not identified in previous research as belonging to groups that are superior in lie detection, attempted to detect truths and lies told by suspects during their videotaped police interviews. Accuracy rates were higher than those typically found in deception research and reached levels similar to those obtained by specialized lie detectors in previous research. Accuracy was positively correlated with perceived experience in interviewing suspects and with mentioning cues to detecting deceit that relate to a suspect's story. Accuracy was negatively correlated with popular stereotypical cues such as gaze aversion and fidgeting. As in previous research, accuracy and confidence were not significantly correlated, but the level of confidence was dependent on whether officers judged actual truths or actual lies and on the method by which confidence was measured.     

False reports of childhood events in appropriate interviews

The present study employed the "parental misinformation" paradigm to examine whether individuals report false events from their childhood even when they are interviewed in an appropriate manner by a trained interviewer. Each participant was interviewed on three occasions. By the final interview, one participant produced a "full" report, and six participants produced "partial" reports, of childhood events that did not occur. Although participants reported perceiving greater pressure to report the false events than the real events, independent judges' ratings of social pressure in the interviews did not differ as a function of what type of event participants were being asked about. Participants also reported higher confidence in their parents', compared to their own, recall of events from their childhood. False reports were also positively correlated with scores on both the full and the revised versions of the Dissociative Experiences Scale, and negatively correlated with score on the Self-Monitoring scale. These results indicate that, despite being interviewed in an appropriate manner by a trained interviewer, some participants will falsely report events from their childhoods.     

Online versus offline processing of visual feedback in the control of movement amplitude

Researchers have suggested that visual feedback not only plays a role in the correction of errors during movement execution but that visual feedback from a completed movement is processed offline to improve programming on upcoming trials. In the present study, we examined the potential contribution of online and offline processing of visual feedback by analysing spatial variability at various kinematic landmarks in the limb trajectory (peak acceleration, peak velocity, peak negative acceleration and movement end). Participants performed a single degree of freedom video aiming task with and without vision of the cursor under four criterion movement times (225, 300, 375 and 450 ms). For movement times of 225 and 300 ms, the full vision condition was less variable than the no vision condition. However, the form of the variability profiles did not differ between visual conditions suggesting that the contribution of visual feedback was due to offline processes. In the 375 and 450 ms conditions, there was evidence for both online and offline control as the form of the variability profiles differed significantly between visual conditions.     

Evidence for the substantia nigra pars compacta as an essential component of a memory system independent of the hippocampal memory system

The aim of the present study was to test if the nigrostriatal pathway is an essential component for a water maze cued task learning and if it works independently of the hippocampal memory system. This hypothesis was tested using an animal model of Parkinson's disease in which male Wistar rats were lesioned in the substantia nigra pars compacta (SNc) by the intranigral infusion of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP), thus causing a partial depletion of striatal dopamine. SNc-lesioned and sham-operated animals were implanted bilaterally with guide cannulae above the dorsal hippocampus in order to be tested after the administration of 0.4 microl 2% lidocaine or saline into this structure. The animals were tested in a spatial or in a cued version of the water maze, memory tasks previously reported to model hippocampal-dependent spatial/relational and striatal-dependent S-R learning, respectively. Hippocampal inactivation, but not SNc lesion, impaired learning and memory in the spatial version of the water maze. An opposite situation was observed with the cued version. No significant interaction was observed between the SNc lesion and hippocampal inactivation conditions affecting scores in the spatial or in the cued version of the water maze. These results suggest that the nigrostriatal pathway is an essential part of the memory system that processes S-R learning and that it works independently of the hippocampal memory system that processes spatial/relational memories.     

Emotional effect of physical aggression among adults in the general population in a Canadian province

The emotional effect of personal involvement in physical aggression was examined in a random sample of 1,753 adults from Ontario, Canada, using Computer Assisted Telephone Interviewing (response rate of 67%). Respondents reported a range of emotional responses from feeling good or justified to feeling angry, upset, terrified, disgusted, hurt, and embarrassed. Open-ended responses regarding emotional response were rated by the authors for 149 incidents of aggression, which yielded five categories: (1) positive impact 4%, (2) no feeling or no effect 31%, (3) mildly negative 20%, (4) moderately negative 28%, and (5) severely negative 17% (Kappa statistic of interrater agreement=.77). The substantial proportion of incidents involving positive or no emotional response suggests that a greater understanding of aggression among individuals can be gained by the development and application of a quantitative measure of emotional response that reflects the full range of emotions (positive and negative), using dimensions identified in this study such as feeling upset, fear, and anger.
