Preventing Maltreatment with a Community-Based Implementation of Parent–Child Interaction Therapy

The purpose of this study was to examine rates of child abuse and neglect reports following a community implementation of Parent–Child Interaction Therapy (PCIT), an evidence-supported intervention for the prevention of maltreatment. Among a group of families receiving PCIT, predictors of reports were examined including family demographics, course of treatment, changes in clinical measures, and caregiver report for prior maltreatment victimization and perpetration. Participants (n = 120) included families at-risk for future maltreatment with and without prior maltreatment history. Agency case records were linked with state administrative records of child welfare reports. Time to follow-up ranged from 13 to 40 months. Bivariate and multivariate survival analyses were used to model risk for a later report. During the follow-up period, 12.5 % of families had a report for physical abuse or neglect. Reports of prior victimization as a child and prior perpetration as an adult were strong predictors of a report of perpetration after PCIT. Dosage of PCIT and change in clinical measures did not increase risk for a later report. PCIT can be an effective intervention for preventing maltreatment. Family history of child welfare involvement is a prominent factor in assessing risk for future involvement.     

Health Related Quality of Life and Social Support in Pediatric Patients with Pacemakers

Prior research evaluating health-related quality of life (HRQOL) among pediatric patients with internal cardiac devices has primarily focused on children with cardiac defibrillators, with scant attention devoted to pacemaker recipients. Social support has been conceptualized as a protective factor that partially accounts for differences in HRQOL. This study compares the HRQOL of children with pacemakers with that of healthy children, and examines associations between HRQOL and social support. Twenty-seven pediatric pacemaker recipients completed measures of HRQOL and social support. Their parents also completed measures of child HRQOL. High concordance was found for child and parent-proxy reports of child HRQOL. Children with pacemakers and their parents both reported relatively low child HRQOL when compared to published normative data for healthy children and parents of healthy children. Family and friends emerged as the sources of support positively associated with the greatest number of HRQOL domains. In conclusion, these findings suggest that pediatric pacemaker recipients experience lower levels of HRQOL compared to healthy peers, and that social support from those closest to the child is associated with their perceived HRQOL.     

On Lions and Adolescents: Affective Temperaments and the Influence of Negative Stimuli on Memory

The present study investigated the relation between reaction to negative stimuli and memory for stimuli. The relation was further investigated using as a framework individuals’ affective temperaments (AFTs). Eighty adolescents participated in the study. The AFTs are based on selfreported affect and categorizes individuals in four temperaments: self-actualizing, high affective, low affective and self-destructive. Reaction to negative stimuli was measured by interpretation of specific words in a short story. Two days later, participants were presented with a list of words and asked which of them were present in the short story. Individuals’ AFTs were expected to predict the promotion of pleasure or the prevention of displeasure. On a general level, reaction to negative stimuli predicted memory for negative, positive and neutral words. At an individual level, self-actualizers and high affectives’ negative reaction predicted the memory of positive words (i.e., promotion). In contrast, low affectives’ negative and positive reaction predicted the memory of neutral words (i.e., prevention).     

Using a runway paradigm to assess the relative strength of rats’ motivations for enrichment objects

Laboratory animals should be provided with enrichment objects in their cages; however, it is first necessary to test whether the proposed enrichment objects provide benefits that increase the animals’ welfare. The two main paradigms currently used to assess proposed enrichment objects are the choice test, which is limited to determining relative frequency of choice, and consumer demand studies, which can indicate the strength of a preference but are complex to design. Here, we propose a third methodology: a runway paradigm, which can be used to assess the strength of an animal’s motivation for enrichment objects, is simpler to use than consumer demand studies, and is faster to complete than typical choice tests. Time spent with objects in a standard choice test was used to rank several enrichment objects in order to compare with the ranking found in our runway paradigm. The rats ran significantly more times, ran faster, and interacted longer with objects with which they had previously spent the most time. It was concluded that this simple methodology is suitable for measuring rats’ motivation to reach enrichment objects. This can be used to assess the preference for different types of enrichment objects or to measure reward system processes.     

The sustained effect of emotional signals on neural processing in 12‐month‐olds

Around the end of the first year of life, infants develop a social referencing ability – using emotional information from others to guide their own behavior. Much research on social referencing has focused on changes in behavior in response to emotional information. The present study was an investigation of the changes in neural responses that underlie social referencing behavior, reflected in event‐related potentials (ERPs). Twenty‐six 12‐month‐olds participated in a single‐session visit in which ERPs were recorded both immediately before and after a behavioral intervention in which infants' caregivers provided positive, negative or neutral information about each of three stimuli (ERP data available for n = 17). After the intervention, infants devoted more neural resources to processing negative versus neutral and positive information, as observed in early and late positive‐going components. Changes in neural responses from the pre‐ to post‐intervention recordings clarify this observation, indicating a sustained response in the negative and positive conditions, and a decrease in the neutral condition, suggesting an attenuation effect in the neutral condition. Further, infants who attended most to the objects in the behavioral intervention showed increased neural responses in the negative condition and decreased responses in the positive condition. Taken together, these findings suggest that infants' neural responses are differentially affected by positive, negative and neutral information. Furthermore, the findings highlight the importance of measuring the change in neural responses to better interpret post‐experience responses.     

Transfer between Picture Books and the Real World by Very Young Children

Picture book reading is a very common form of interaction between parents and very young children. Here we explore to what extent young children transfer novel information between picture books and the real world. We report that 15- and 18-month-olds can extend newly learned labels both from pictures to objects and from objects to pictures. However, the degree to which they do so is affected by iconicity—how much the objects and pictures resemble one another. The children in these studies more often extended the labels between picture and object when realistic photographs and drawings were involved than less realistic cartoons. These results show that higher levels of perceptual similarity between symbol and referent make the referential relation more transparent, thereby helping children transfer information between them. Thus, the educational function of early picture book interactions may best be served with realistic illustrations.     

Toward a Comprehensive Understanding of Officers’ Shooting Decisions: No Simple Answers to This Complex Problem

Police officers make life-or-death shooting decisions in complex situations under extreme time pressure. If officers make a mistake, there are dire consequences—they could kill an innocent or be killed themselves. In contrast to prior work's near-exclusive focus on suspect race, the present study examined features of methodology, officers, suspects, and neighborhoods that may affect officers’ shooting decisions. Empirical exploration of officers’ shooting decisions and mistakes is still in its infancy, and given the seriousness and importance of this phenomenon—and the potential for this research to inform policy decisions—additional research is needed.     

The relativity of time perception produced by facial emotion stimuli

Insults elicit intense emotion. This study tests the hypothesis that one's social image, which is especially salient in honour cultures, influences the way in which one reacts to an insult. Seventy-seven honour-oriented and 72 non-honour oriented participants answered questions about a recent insult episode. Participants experienced both anger and shame in reaction to the insult. However, these emotions resulted in different behaviours. Anger led to verbal attack (i.e., criticising, insulting in return) among all participants. This relationship was explained by participants’ motivation to punish the wrongdoer. Shame, on the other hand, was moderated by honour. Shame led to verbal disapproval of the wrongdoers behaviour, but only among the honour-oriented participants. This relationship was explained by these participants’ motivation to protect their social image. By contrast, shame led to withdrawal among non-honour-oriented participants.     

Coping with the 10th anniversary of 9/11: Muslim Americans' sadness,fear, and anger

The events of 9/11 marked an increase in prejudice, discrimination, and other forms of unfair treatment toward Muslim Americans. We present a study that examined the emotions of Muslim Americans in the days preceding the ten-year 9/11 anniversary. We measured the antecedents (concerns) and consequences (coping) of sadness, fear, and anger. The 9/11 anniversary precipitated intense concerns with loss and discrimination, and intense feelings of sadness, fear, and anger. We measured three coping responses: rumination, avoidance of public places, and religious coping. Participants engaged in all three coping responses, with seeking solace in one's religion being the most frequent response. Moreover, emotions mediated the relationship between concerns and coping responses. Sadness accounted for the association between concern with loss and rumination. Fear explained the association between concern with discrimination and avoidance. Anger accounted for the association between concern with discrimination and religious coping.     

Cognitive bias and emotion in neuropsychological models of depression

Neuropsychological models of depression were tested by examining encoding and recognition biases elicited by emotional stimuli manifested in regional brain wave activity. Participants were pre-exposed to emotional stimuli. These stimuli were presented again embedded in new stimuli, and event-related brain potentials (ERPs) were recorded while participants judged whether they had viewed each stimulus previously. Controls showed an enhanced P300 during encoding and reduced P300 during recognition of positive stimuli, indicating a response bias for positive information. In contrast, participants diagnosed with major depression showed no valence difference during encoding of new stimuli or recognition of old stimuli. These results suggest positive cognitive biases in controls and a lack of such a biases in depressed individuals. Additionally, regression analyses demonstrated that a substantial proportion of P300 variance was related to clinical scale
