Intolerance of uncertainty and novelty facilitated extinction: The impact of reinforcement schedule

Individuals who score high in intolerance of uncertainty (IU) display reduced threat extinction. Recently, it was shown that replacing threat associations with novel associations during extinction learning (i.e., presenting a novel tone 100% of the time) can promote threat extinction retention in individuals with high IU. This novelty facilitated extinction (NFE) effect could be driven by the tone's novelty or reliability. Here, we sought to address this question by adjusting the reliability of the novel tone (i.e., the reinforcement rate) during NFE. We measured skin conductance response during an associative learning task in which participants (n = 92) were assigned to one of three experimental groups: standard extinction, NFE 100% reinforcement, or NFE 50% reinforcement. For standard extinction, compared to NFE 100% and 50% reinforcement groups, we observed a trend for greater recovery of the conditioned response during extinction retention. Individuals with high IU relative to low IU in the standard extinction group demonstrated a larger recovery of the conditioned response during extinction retention. These findings tentatively suggest that NFE effects are driven by the novelty rather than the reliability of the new stimulus. The implications of these findings for translational and clinical research in anxiety disorder pathology are discussed.     

The Role of Social and Cognitive Processes in the Relationship Between Fear Network and Psychological Distress Among Parents of Children Undergoing Hematopoietic Stem Cell Transplantation

The current study examined whether cognitive and social processing variables mediated the relationship between fear network and depression among parents of children undergoing hematopoietic stem cell transplant (HSCT). Parents whose children were initiating HSCT (N = 179) completed survey measures including fear network, Beck Depression Inventory, cognitive processing variables (positive reappraisal and self-blame) and social processing variables (emotional support and holding back from sharing concerns). Fear network was positively correlated with depression (p < .001). Self-blame and holding back emerged as individual partial mediators in the relationship between fear network and depression. Together they accounted for 34.3 % of the variance in the relationship between fear network and depression. Positive reappraisal and emotional support did not have significant mediating effects. Social and cognitive processes, specifically self-blame and holding back from sharing concerns, play a negative role in parents’ psychological adaptation to fears surrounding a child’s HSCT.     

Domesticated dogs’ (Canis familiaris) use of the solidity principle

Organisms must often make predictions about the trajectories of moving objects. However, often these objects become hidden. To later locate such objects, the organism must maintain a representation of the object in memory and generate an expectation about where it will later appear. We explored adult dogs’ knowledge and use of the solidity principle (that one solid object cannot pass through another solid object) by evaluating search behavior. Subjects watched as a treat rolled down an inclined tube into a box. The box either did or did not contain a solid wall dividing it in half. To find the treat, subjects had to modify their search behavior based on the presence or absence of the wall, which either did or did not block the treat’s trajectory. Dogs correctly searched the near location when the barrier was present and the far location when the barrier was absent. They displayed this behavior from the first trial, as well as performed correctly when trial types were intermingled. These results suggest that dogs direct their searches in accordance with the solidity principle.     

How Adolescents’ Mental Health Predicts Their Physical Health: Unique Contributions of Indicators of Subjective Well-being and Psychopathology

Studies among youth have established a link between mental health and physical health, and highlight the importance of attending to these relationships to provide a more complete picture of functioning. However, most previous investigations have limited their focus to examining the relationship between physical health and either particular aspects of psychopathology or particular aspects of subjective well-being. The current study serves as a first examination that includes both positive (subjective well-being [SWB]) and negative (psychopathology) indicators of mental health in relation to physical health functioning, assessed via self-report measures completed by a sample of 401 early adolescents from the general population. Mental health indicators accounted for 30% of the variance in physical health ratings, and 4 of the 5 mental health indicators were unique predictors of physical health. Positive affect, a component of SWB, explained the most unique variance in physical health, followed by the other components of SWB. Results support the importance of attending to positive indicators of mental health when determining the link with physical health among youth. Implications for a research and practice focus on comprehensive wellness among youth are discussed.     

Suppression of emotional stroop effects by fear-arousal

Abstract

Previous studies have suggested that subjects are slower to colour-name emotional words, when the meaning of these words is related to a fear or current concern. We carried out three experiments on subjects having either high or low fear of snakes, with the aim of replicating this finding, and of testing the effects of arousing fear in subjects at the same time. Unexpectedly, we could only replicate the predicted interference effect in the absence of threat, whether due to a snake or to another threatening stimulus. We conclude that emotional interference effects do depend on high levels of fearfulness or trait anxiety, and on a match between the content of the subjects' concerns and the meaning of the interfering material. However, this interference may be paradoxically obscured by fear arousal, or the presence of a real danger that alters processing priorities in highly fearful subjects.     

Parental Characteristics,Ecological Factors,and the Academic Achievement of African American Males

Parental characteristics, ecological factors, and the academic achievement of African American male high school students were examined. One hundred fifty‐three 11th and 12th grade African American males completed the Parenting Style Index ( Steinberg, Lamborn, Darling, Mounts, & Dornbusch, 1994 ) and a demographic questionnaire. Results indicated no significant relationship between parenting styles and enrollment in honors courses. However, the results indicated that fathers’ education level and two‐parent family structures are positive predictors of grade point average (GPA), and fathers’ expectations is a negative predictor of GPA. Implications for counselor practice and research are delineated.     

The Relationship Between Postdeployment Factors and PTSD Severity in Recent Combat Veterans

Combat traumas precipitate posttraumatic stress disorder (PTSD); however, nontraumatic deployment and postdeployment factors may also contribute to PTSD severity. The Deployment Risk and Resilience Inventory (DRRI) was used to investigate pre-, peri-, and postdeployment factors associated with current PTSD severity in 150 recent combat veterans with PTSD and hazardous alcohol use. Hierarchal linear regression analyzed what factors independently predicted PTSD severity when controlling for sociodemographic characteristics and combat specific variables. Four postdeployment factors independently predicted PTSD severity: unemployment, alcohol use, social support, and stressful (nontraumatic) life events. The centrality of trauma in the maintenance of PTSD and clinical implications for treatment providers are discussed.     

“Good job, you’re so smart”: The effects of inconsistency of praise type on young children’s motivation

Previous research has demonstrated that generic praise (“good drawer”) is related to children giving up after failure because failure implies the lack of a critical trait (e.g., drawing ability). Conversely, nongeneric praise (“good job drawing”) is related to mastery motivation because it implies that success is related to effort. Yet children may receive a mixture of these praise types (i.e., inconsistent praise), the effects of which are unclear. We tested how inconsistent praise influenced two components of motivation: self-evaluation and persistence. Kindergarteners (N = 135) were randomly assigned to one of five conditions in which consistency of praise type was varied. After two failure scenarios, children reported self-evaluations and persistence. Results indicated that more nongeneric praise related linearly to greater motivation, yet self-evaluation and persistence were impacted differently by inconsistent praise types. Hearing even a small amount of generic praise reduced persistence, whereas hearing a small amount of nongeneric praise preserved self-evaluation.     

Is compassion for others stress buffering? Consequences of compassion and social support for physiological reactivity to stress

The present study examined the role of compassion for others and social support in physiological stress reactivity. In this experiment, participants who had previously completed an online assessment of compassion experienced a social stress task in front of either two supportive or neutral evaluators, while their blood pressure, cortisol, high frequency heart rate variability (HF-HRV), and liking for the evaluators were monitored. Participants’ compassion for others interacted with social support condition to buffer their physiological reactivity to stress. When provided with social support during the task, higher trait compassion was associated with lower blood pressure reactivity, lower cortisol reactivity, and higher HF-HRV reactivity. Higher compassion was also associated with greater liking for the supportive evaluators. These relationships were not observed for participants in the neutral condition, regardless of their trait compassion. Compassion for others may increase our ability to receive social support, which may lead to more adaptive profiles of stress reactivity.     

Systems Factorial Technology provides new insights on global-local information processing in autism spectrum disorders

Previous studies of global-local processing in autism spectrum disorders (ASDs) have indicated mixed findings, with some evidence of a local processing bias, or preference for detail-level information, and other results suggesting typical global advantage, or preference for the whole or gestalt. Findings resulting from this paradigm have been used to argue for or against a detail focused processing bias in ASDs, and thus have important theoretical implications. We applied Systems Factorial Technology, and the associated Double Factorial Paradigm (both defined in the text), to examine information processing characteristics during a divided attention global-local task in high-functioning individuals with an ASD and typically developing controls. Group data revealed global advantage for both groups, contrary to some current theories of ASDs. Information processing models applied to each participant revealed that task performance, although showing no differences at the group level, was supported by different cognitive mechanisms in ASD participants compared to controls. All control participants demonstrated inhibitory parallel processing and the majority demonstrated a minimum-time stopping rule. In contrast, ASD participants showed exhaustive parallel processing with mild facilitatory interactions between global and local information. Thus our results indicate fundamental differences in the stopping rules and channel dependencies in individuals with an ASD.
