Changes in ADHD Symptom Endorsement: Preschool to School Age

To investigate endorsement patterns among the 18 DSM-IV symptoms of ADHD in a longitudinal sample of children with and without ADHD (n?=?144), as assessed at ages 4-5, 5-6, and 6-7 years. Symptom endorsements and diagnoses were determined at all time-points via K-SADS-PL interview administered to parents and supplemented by teacher questionnaires and clinician observations. Changes in endorsement patterns over time for each of the 18 DSM-IV symptoms were ascertained. Several symptoms, particularly those of inattention, were infrequently endorsed and of apparently limited diagnostic utility at ages 4-5; hyperactive/impulsive symptoms were more frequently endorsed among young children with ADHD than were inattentive symptoms. However, by ages 6-7, inattention items were somewhat superior at discriminating ADHD from Non-ADHD children. Several DSM-IV and now DSM-V symptoms provide limited diagnostic differentiation prior to school-age, particularly those most commonly observed in the context of formal schooling. Consideration should be made in future iterations of the DSM that account for such developmental and contextual differences.     

On feeling good at work: the role of regulatory mode and passion in psychological adjustment

The major postulate of this work is that regulatory modes influence the type of passion people experience with regard to an activity, which in turn influences their psychological adjustment. Integrating regulatory mode theory and the dualistic model of passion, we hypothesized that locomotion—associated with intrinsic and autonomous motivations—would positively predict harmonious passion, which in turn would enhance workers' psychological adjustment. In contrast, we hypothesized that assessment—associated with extrinsic and non‐autonomous motivations—would positively predict obsessive passion, which in turn would reduce workers' psychological adjustment. Two field studies supported these hypotheses with psychological adjustment measures of stress (Study 1) and burnout (Study 2) in different work contexts.     

Positive affect as a moderator of liking effects on trust and attraction

Attitude similarity effects on attraction appear to be mediated sequentially by positive affect, inferred attraction, and trust. That is, the first two supposedly distal mediators influence each other in building trust, a mediator proximal to attraction. However, the correlational nature of data reported heretofore precludes definitive conclusions about sequential dependency between the two distal mediators. In the research reported, therefore, the authors manipulated positive affect in the participants (Time 1) and liking of the partner for them (Time 2), and measured trust before attraction. As predicted, liking effects on trust and attraction were stronger when positive affect in the participants was high than when it was low. Importantly, the interaction effect in trust fully mediated the interaction effect in attraction.     

An evaluation of matrix training to teach college students piano notes and rhythms

Twelve college students learned to tact the names of notes and rhythms and play them when presented with compound stimuli (visuals of notes and rhythms on a musical staff). In Experiment 1, we assessed generalization by presenting novel notes, rhythms, and compound stimuli not previously paired together. In the second experiment, we added a metronome that played at 60 beats per minute in all conditions for 3 out of 6 participants to ensure consistent tempo. Across both experiments, participants passed almost all posttests with the exception of tacting and playing in the presence of sound clips. Our data suggest that matrix training is an effective procedure to teach music skills to college students.     

Sleep Increases Susceptibility to the Misinformation Effect

When individuals witness an event and are exposed to misleading postevent information, they often incorporate the misleading information into their memory for the original event, a phenomenon known as the misinformation effect. The present study examined the role of sleep in the misinformation effect. Participants (N = 177) witnessed two events; were exposed to misleading postevent information immediately, 12 hours later the same day, 12 hours later the next day, or 24 hours later; and then took a recognition test. All groups demonstrated the misinformation effect, and this effect was larger in groups with an overnight retention interval. Signal detection analyses revealed that sleep decreased sensitivity. These results suggest that sleep increases susceptibility to the misinformation effect, which may occur because sleep results in gist‐based representations of original events or because sleep improves learning of postevent information. Implications for interviewing eyewitnesses are discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

The misinformation effect is unrelated to the DRM effect with and without a DRM warning

The misinformation and Deese–Roediger–McDermott (DRM) paradigms are used to study forms of false memories. Despite the abundance of research using these two paradigms, few studies have examined the relationship between the errors that arise from them. In the present study, 160 participants completed a misinformation task and two DRM tasks, receiving a warning about the effect before the second DRM task. Participants demonstrated misinformation and DRM effects (with and without the warning), but susceptibility to these forms of false memory were not significantly related across individuals. The DRM warning reduced the DRM effect, and signal detection analysis revealed that the DRM warning reduced a liberal response bias in this task. Sensitivity and response bias in both DRM tasks were not significantly related to these measures in the misinformation task. These findings suggest that these two forms of false memories are not interchangeable and they appear to be the result of different cognitive processes.     

‘You Wouldn’t have Your Granny Using Them’: Drawing Boundaries Between Acceptable and Unacceptable Applications of Civil Drones

Some industry and policy actors are concerned about public opposition to civil drones, in particular because of their association with military drones. However, very little is understood about public reactions to the technology. Strategies to ‘manage public acceptance’ have so far relied upon several untested assumptions. We conducted public engagement activities to explore citizens’ visions of civil drones. Several insights counteracted the prevailing assumptions. Rejecting the notion of blanket support for or opposition to civil drones, we found that citizens make nuanced decisions about the acceptability of civil drones depending upon the purpose of the flight and the actors involved. The results are positioned in support for calls to strengthen the role of citizens in civil drone development and, in particular, to shift away from the current focus on citizens’ acceptance of civil drone development towards the development of civil drones that are acceptable to citizens.     

Essentialist beliefs affect children's outgroup empathy,attitudes and prosocial behaviours in a setting of intergroup conflict

Empathy for salient outgroups can promote positive intergroup attitudes and prosocial behaviours. Less is known about which factors may promote empathy, particularly among children, in contexts of intergroup conflict. Empathy may depend on underlying cognitions, such as social essentialist beliefs, that is, believing that certain social categories have an underlying essence that causes members to share observable and non-observable properties. This study explored the influence of essentialist beliefs about ethno-religious categories on outgroup-directed empathy, attitudes and prosocial behaviours of children living in Northern Ireland (N = 88; M = 7.09, SD = 1.47 years old). Bootstrapped chain mediation found that lower essentialist beliefs predicted greater outgroup-directed empathy, which was positively related to outgroup attitudes, which in turn, predicted more outgroup prosocial behaviours. The findings highlight the importance of essentialist beliefs as an underlying factor promoting empathy, with links to prosocial behaviours in settings of intergroup conflict. The intervention implications are discussed.
