Validation of the Chinese Revision of Emotional and Behavioral Screener among Preschoolers (4–7 years old)

The study aimed to examine the psychometric properties of the Chinese revision of the Emotional and Behavioral Screener (EBS), and to extend its application to preschoolers (4–7 years old). Teachers and parents of 216 preschoolers (age M?=?5.11, SD?=?0.9) were invited to complete the EBS, and some of the teachers were also asked to complete the Preschool Behavioral and Emotional Rating Scale (PreBERS) (N?=?80) and the Strength and Difficulties Questionnaires (SDQ) (N?=?90). Results of confirmatory factor analysis suggested that the original single-factor model of the EBS didn’t fit the data well. Based on the results of a series of exploratory factor analyses, we proposed a two-factor model instead, representing externalizing and internalizing problems respectively. The Chinese revision demonstrated satisfactory internal reliability, inter-rater reliability, convergent validity and divergent validity. All these evidences supported its use among Chinese preschoolers to identify those who will be at risk of suffering from emotional and behavioral disturbances.     

Longitudinal Associations between Oppositional Defiant Symptoms and Interpersonal Relationships among Chinese Children

Children with oppositional defiant disorder (ODD) are at increased risk for developing poor relationships with people around them, but the longitudinal links between ODD symptoms and subsequent interpersonal functioning remain unclear. In the current study, we examined the bidirectional associations between ODD symptoms and children’s relationships with parents, peers, and teachers. We included separate analyses for parent vs. teacher reports of ODD symptoms, with regard to subsequent interpersonal relationships. Participants included 256 children with ODD, recruited in China, along with their parents and teachers, assessed at three time points roughly two years apart. Parents and teachers reported child ODD symptoms at each time point, and children reported their perceptions of father– and mother–child attachment, peer relationships, and teacher–student relationships across the three time points. ODD symptoms reported either by parents or teachers predicted impairments in interpersonal functioning. Meanwhile, child interpersonal impairments with peers and teachers predicted subsequent increase in teacher-reported ODD symptoms. These findings highlight the importance of transactional models of influence—and of considering early intervention for ODD in protecting children from developing further deficits and impairments. Additionally, we discuss the perspectives of multiple informants on ODD symptoms, including their different patterns of association with subsequent interpersonal relationships.     

Discrimination threshold for haptic volume perception of fingers and phalanges

Humans exhibit a remarkable ability to discriminate variations in object volume based on natural haptic perception. The discrimination thresholds for the haptic volume perception of the whole hand are well known, but the discrimination thresholds for haptic volume perception of fingers and phalanges are still unknown. In the present study, two psychophysical experiments were performed to investigate haptic volume perception in various fingers and phalanges. The configurations of both experiments were completely dependent on haptic volume perception from the fingers and phalanges. The participants were asked to blindly discriminate the volume variation of regular solid objects in a random order by using the distal phalanx, medial phalanx, and proximal phalanx of their index finger, middle finger, ring finger, and little finger. The discrimination threshold of haptic volume perception gradually decreases from the little finger to the index finger as well as from the proximal phalanx to the distal phalanx. Overall, both the shape of the target and the part of the finger in contact with the target significantly influence the precision of haptic perception of volume. This substantial data set provides detailed and compelling perspectives on the haptic system, including for discrimination of the spatial size of objects and for performing more general perceptual processes.     

Perceptual experience shapes our ability to categorize faces by national origin: A new other-race effect

People are better at recognizing own-race than other-race faces. This other-race effect has been argued to be the result of perceptual expertise, whereby face-specific perceptual mechanisms are tuned through experience. We designed new tasks to determine whether other-race effects extend to categorizing faces by national origin. We began by selecting sets of face stimuli for these tasks that are typical in appearance for each of six nations (three Caucasian, three Asian) according to people from those nations (Study 1). Caucasian and Asian participants then categorized these faces by national origin (Study 2). Own-race faces were categorized more accurately than other-race faces. In contrast, Asian American participants, with more extensive other-race experience than the first Asian group, categorized other-race faces better than own-race faces, demonstrating a reversal of the other-race effect. Therefore, other-race effects extend to the ability to categorize faces by national origin, but only if participants have greater perceptual experience with own-race, than other-race faces. Study 3 ruled out non-perceptual accounts by showing that Caucasian and Asian faces were sorted more accurately by own-race than other-race participants, even in a sorting task without any explicit labelling required. Together, our results demonstrate a new other-race effect in sensitivity to national origin of faces that is linked to perceptual expertise.     

Both Earlier Times and the Future Are “Front”: The Distinction Between Time‐ and Ego‐Reference‐Points in Mandarin Speakers’ Temporal Representation

Mandarin speakers, like most other language speakers around the world, use spatial terms to talk about time. However, the direction of their mental temporal representation along the front‐back axis remains controversial because they use the spatial term “front” to refer to both earlier times (e.g., front‐year means “the year before last”) and the future (e.g., front‐road means “prospect”). Although the linguistic distinction between time‐ and ego‐reference‐point spatiotemporal metaphors in Mandarin suggests a promising clarification of the above controversy, there is little empirical evidence verifying this distinction. In this study, Mandarin speakers’ time‐ and ego‐reference‐point temporal representations on three axes (i.e., sagittal, lateral, and vertical) were separately examined through two tasks. In a time‐reference‐point task, Mandarin speakers judged whether the time point of the second picture was earlier or later than the time point of the first picture, while in an ego‐reference‐point task, they judged whether an event or phase had happened in the past or would happen in the future. The results indicate that Mandarin speakers construe an earlier‐times‐in‐front‐of‐later‐times temporal sequence and adopt the front‐to‐the‐future orientation.     

The role of retributive justice and the use of international criminal tribunals in post‐conflict reconciliation

Four experiments examined people's responses to intergroup violence either committed or suffered by their own group. Experiment 1 demonstrated that Serbs who strongly glorified Serbia were more supportive of future violence against, and less willing to reconcile with, Bosniaks after reading about Serbian victimization by Bosniaks rather than Serbian transgressions against Bosniaks. Replicating these effects with Americans in the context of American–Iranian tensions, Experiment 2 further showed that demands for retributive justice explained why high glorifiers showed asymmetrical reactions to ingroup victimization vs. perpetration. Again in the Serb and the American context, respectively, Experiments 3 and 4 demonstrated that post‐conflict international criminal tribunals can help satisfy victim group members' desire for retributive justice, and thereby reduce their support for future violence and increase their willingness to reconcile with the perpetrator group. The role of retributive justice and the use of international criminal justice in intergroup conflict (reduction) are discussed.     

No advantage for remembering horizontal over vertical spatial locations learned from a single viewpoint

Previous behavioral and neurophysiological research has shown better memory for horizontal than for vertical locations. In these studies, participants navigated toward these locations. In the present study we investigated whether the orientation of the spatial plane per se was responsible for this difference. We thus had participants learn locations visually from a single perspective and retrieve them from multiple viewpoints. In three experiments, participants studied colored tags on a horizontally or vertically oriented board within a virtual room and recalled these locations with different layout orientations (Exp. 1) or from different room-based perspectives (Exps. 2 and 3). All experiments revealed evidence for equal recall performance in horizontal and vertical memory. In addition, the patterns for recall from different test orientations were rather similar. Consequently, our results suggest that memory is qualitatively similar for both vertical and horizontal two-dimensional locations, given that these locations are learned from a single viewpoint. Thus, prior differences in spatial memory may have originated from the structure of the space or the fact that participants navigated through it. Additionally, the strong performance advantages for perspective shifts (Exps. 2 and 3) relative to layout rotations (Exp. 1) suggest that configurational judgments are not only based on memory of the relations between target objects, but also encompass the relations between target objects and the surrounding room—for example, in the form of a memorized view.     

Children’s Reward and Punishment Sensitivity Moderates the Association of Negative and Positive Parenting Behaviors in Child ADHD Symptoms

Atypical reward processing, including abnormal reward responsivity and sensitivity to punishment, has long been implicated in the etiology of ADHD. However, little is known about how these facets of behavior interact with positive (e.g., warmth, praise) and negative (e.g., hostility, harsh discipline) parenting behavior in the early expression of ADHD symptoms in young children. Understanding the interplay between children’s reward processing and parenting may be crucial for identifying specific treatment targets in psychosocial interventions for ADHD, especially given that not all children benefit from contingency-based treatments (e.g., parent management training). The study consisted of a sample of kindergarten children (N?=?201, 55% male) and their parents, who completed questionnaires about their parenting practices, their child’s behaviors and participated in an observed parent-child play task in the laboratory. Children’s reward responsivity and sensitivity to punishment were positively associated with child ADHD symptoms. However, children with high reward responsivity had more symptoms of ADHD but only under conditions of low negative parenting (self-reported and observed) and high self-reported positive parenting, compared to children with low reward responsivity. Children with high sensitivity to punishment had more ADHD symptoms relative to children with low sensitivity to punishment, but only under conditions in which observed praise was infrequent. Results provide evidence that individual differences in sensitivity to reward/punishment may be an important of marker of risk for ADHD, but also highlights how children’s responses to positive and negative parenting behavior may vary by children’s sensitivities. Clinical and treatment implications are discussed.     

Autonomic conditioning to monetary and social stimuli and aggression in children

Poor conditioning to punishment, such as loud tones or electric shock, has been proposed as an important factor involved in the etiology of aggressive and psychopathic behavior. However, it is not known whether the association holds when monetary or social stimulus is used as the unconditioned stimulus, and if aggressive individuals also have impaired conditioning to rewards. In this study, skin conductance responses in a conditioning task involving both monetary/social reward and punishment as unconditioned stimuli were assessed in 340 male and female 8‐ to 9‐year‐old children from the community. Children reported their reactive and proactive aggression using the Reactive and Proactive Aggression Questionnaire (RPQ; Raine et al., 2006). Results showed that monetary/social reward and punishment were effective in eliciting physiological classical conditioning in children, and that reduced reward conditioning was associated with high levels of proactive aggression in particular. Findings highlight the importance of distinguishing between reactive and proactive aggression when examining antisocial behavior in children, and suggest that reward‐oriented treatment programs may not be effective for children with more proactive, instrumental aggressive behavior.

     

The natural mathematics of behavior analysis

Models that generate event records have very general scope regarding the dimensions of the target behavior that we measure. From a set of predicted event records, we can generate predictions for any dependent variable that we could compute from the event records of our subjects. In this sense, models that generate event records permit us a freely multivariate analysis. To explore this proposition, we conducted a multivariate examination of Catania's Operant Reserve on single VI schedules in transition using a Markov Chain Monte Carlo scheme for Approximate Bayesian Computation. Although we found systematic deviations between our implementation of Catania's Operant Reserve and our observed data (e.g., mismatches in the shape of the interresponse time distributions), the general approach that we have demonstrated represents an avenue for modelling behavior that transcends the typical constraints of algebraic models.
