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.     

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.     

Concreteness and word production

Two experiments are reported that investigated the effect of concreteness on the ability to generate words to fit sentence contexts. When participants attempted to retrieve words from dictionary definitions in Experiment 1, abstract words were associated with more omissions and more alternates than were concrete words. These findings are consistent with the view that the semantic–lexical weights in the word production system are weaker for abstract than for concrete words. We found no evidence that greater competition from semantic neighbors was an additional reason why abstract words were harder to produce. Participants also reported more positive tip-of-the-tongue states (TOTs) when attempting to produce abstract words from their definitions, consistent with more phonological retrieval problems for abstract than for concrete words. In Experiment 2, participants attempted to generate words to fit into a sentence that described a specific event. The difference between the numbers of abstract and concrete words recalled was significantly smaller in the event condition than in the definition condition, and evidence no longer emerged of greater phonological retrieval failure for abstract words. Overall, the results are consistent with the view that the semantic–lexical weights, but not the lexical–phonological weights, are weaker for abstract than for concrete words in the word production system.     

Evaluation of stimulus control over a communication response as an intervention for stereotypical responding

Stereotypical behavior maintained by automatic reinforcement often does not result in harm but may be undesirable in some situations. In the current investigation, participants were 2 individuals who engaged in nonharmful stereotypical responses shown in an analogue functional analysis to be insensitive to social contingencies. After bringing these responses under stimulus control using differential punishment, both participants learned a mand to terminate punishment for stereotypy. We also assessed whether the mand could be brought under stimulus control.     

“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.     

Neurocognitive perspectives in language outcomes of Early Head Start: Language and cognitive stimulation and maternal depression

A neurocognitive, developmental framework was used to examine the effectiveness of Early Head Start (EHS) programs. Evidence has shown that caregiver variables impact early brain development. This study aimed to better understand this relation. Results showed that the EHS program made no significant impact, and at 3 years old, children were significantly behind population norms in language development, partially replicating previous findings with children from poverty backgrounds. EHS and parental depression were significant predictors of language and cognitive stimulation; however, depression and stimulation, but not involvement in EHS, were significant predictors of vocabulary. Implications for EHS programs are discussed, such as addressing caregiver variables (e.g., depression) and increasing focus on services to expectant families. Future directions also are discussed, such as understanding how young children's stress, within the context of caregiver variables, is related to neurocognitive outcomes.     

Providing Care for the “Whole Patient” in the Cancer Setting: The Psycho-Oncology Consultation Model of Patient Care

This paper describes a psycho-oncology consultation model of care (POCM) that provides a framework for psychosocial clinical work with cancer patients. Goals for care are addressed that follow the recommendations of the Institute of Medicine report advocating care for the “whole patient.” Specific goals include reducing distress and symptoms, building on the patient’s existing strengths, enhancing self-efficacy, expanding the patient’s repertoire of healthy coping strategies, and addressing informational needs. Specific interventions are described that clinicians can implement in order to address the above goals. The paper also addresses the unique challenges encountered in working with cancer patients, as well as programmatic difficulties that are inherent in providing mental health care in a medical setting.
