Repetition blindness in sentence contexts: Not just an attribution?

Selective "blindness" to repeated words in rapid serial visual presentation (RSVP) occurs even when omitting these words compromises sentence syntax and meaning. The contributions of lexical and contextual factors to this repetition blindness (RB) phenomenon were evaluated using three tasks that combined RB and ambiguity resolution paradigms. During an RSVP sentence, a repeated word and matched but incongruous control were presented simultaneously, and participants were asked to report the entire sentence, including only the appropriate word. Substantial RB was evident in impaired report of repeated targets, whereas report of nonrepeated targets was enhanced when the distractor was a repeat. Experiment 2 confirmed these results with reduced reporting requirements, and Experiment 3 demonstrated the independence of repetition and sentence congruity effects. Results across all contexts support a lexical account of RB, which assumes that reactivation and identification of rapidly repeated words are impaired due to the refractory nature of lexical representations.     

The effect of early cognitions on cigarette and alcohol use during adolescence

The present study predicts cigarette and alcohol use in adolescence from the development of children's cognitions in the elementary years. Using latent growth modeling, the authors examined a model using data from 712 participants in the Oregon Youth Substance Use Project, who were in the 2nd through 5th grade at the 1st assessment and followed for 6 annual or semiannual assessments over 7 years. Growth in children's prototypes and subjective norms in the elementary years (Times 1 through 4) were related to their substance use in adolescence (Time 6) through their willingness and intentions (Time 5) to smoke and drink. Across the sample, for both substances, the intercept and slope of prototypes were either indirectly related to use through willingness or directly related to use. Both the intercept and slope of subjective norms were indirectly related to use of both substances through both willingness and intentions and directly related to cigarette use. Results suggest that elementary children have measurable cognitions regarding substance use that develop during the elementary years and predict use later in adolescence. These findings emphasize the need for prevention programs targeted at changing children's social images of substance users and encouraging more accurate perceptions of peers' use.     

The Hill Interaction Matrix

The Hill Interaction Matrix represents a system of classifying group process and group progress, which has been empirically derived and systematically researched. Leadership style, group composition, and group development are simultaneously quantified through the use of this matrix. It represents an attempt to objectify the art of group therapy.     

Radon and cigarette smoking: perceptions of this synergistic health risk.

Past approaches to the measurement of the perceived risk of combined hazards have failed to demonstrate awareness of synergy (S. E. Hampson et al., 1998; D. Hermand, E. Mullet, & B. Coutelle, 1995; D. Hermand, E. Mullet, & S. Lavieville, 1997). Respondents (N = 650) were provided with information about the synergistic risk of lung cancer from the combination of smoking and radon, and their risk perceptions were assessed on two occasions. At Time 1, using Likert-type scales, there was no evidence of synergistic risk perception. At Time 2, using a scale based on the appraisal of relative risk with anchors allowing for the expression of synergy, the combined hazard of radon and smoking was rated as significantly more of a health risk than the single hazards. The findings are discussed in terms of methodological issues in assessing synergistic risk.     

Optimizing Contingency Management With Methamphetamine-Using Men Who Have Sex With Men

Among men who have sex with men (MSM), methamphetamine use is associated with multiple, overlapping syndemic conditions including increased risk for HIV seroconversion and onward HIV transmission. Contingency management (CM) is an evidence-based behavioral intervention implemented to curb methamphetamine use and optimize HIV/AIDS prevention among MSM in San Francisco since 2003. We conducted a program evaluation to document the evolution of this 12-week CM program to include delivery of brief, individual counseling incorporating motivational interviewing and behavioral skills. A drop-in group delivered concurrently with CM urine-screening visits also provides peer support as well as referrals for other social and medical services. From December 2011–October 2013, a total of 131 clients enrolled in the CM program and provided a median of 22 urine samples (Interquartile Range = 10–34) that were nonreactive for methamphetamine. Findings support the feasibility and acceptability of integrating individual and group counseling with community-based CM for methamphetamine-using MSM.     

Acceptability of,and Information Needs Regarding,Next-Generation Sequencing in People Tested for Hereditary Cancer: A Qualitative Study

Next generation sequencing (NGS) for patients at risk of hereditary cancer syndromes can also identify non-cancer related mutations, as well as variants of unknown significance. This study aimed to determine what benefits and shortcomings patients perceive in relation to NGS, as well as their interest and information preferences in regards to such testing. Eligible patients had previously received inconclusive results from clinical mutation testing for cancer susceptibility. Semi-structured telephone interviews were subjected to qualitative analysis guided by the approach developed by Miles and Huberman. The majority of the 19 participants reported they would be interested in panel/genomic testing. Advantages identified included that it would enable better preparation and allow implementation of individualized preventative strategies, with few disadvantages mentioned. Almost all participants said they would want all results, not just those related to their previous diagnosis. Participants felt that a face-to-face discussion supplemented by an information booklet would be the best way to convey information and achieve informed consent. All participants wanted their information stored and reviewed in accordance with new developments. Although the findings indicate strong interest among these individuals, it seems that the consent process, and the interpretation and communication of results will be areas that will require revision to meet the needs of patients.     

Psychological,endocrine, and neural correlates of attentional bias in subclinical depression

Background: Our knowledge with respect to psychological, endocrine, and neural correlates of attentional bias in individuals with high vulnerability to developing depression – the subclinically depressed, still remains limited. Design: The study used a 2?×?2 mixed design. Methods: Attentional bias toward happy and sad faces in healthy (N?=?26) and subclinically depressed individuals (N?=?22) was assessed via a neuroimaging dot-probe attention task. Participants also completed trait and state psychological measures and provided saliva samples for cortisol analysis. Results: The subclinical group showed attentional bias toward happy faces; past use of problem-focused coping strategies when dealing with a personally relevant stressor as well as state levels of anxiety, together, contributed to this bias. In the control group, the happy attentional bias was positively correlated with activity in the right caudate. In the subclinical group, the bias was negatively associated with the left fusiform gyrus and positively with the left inferior parietal lobule and bilateral putamen. We observed group differences in association between cortisol levels during the task and neural activity during happy attentional bias processing within the key regions involved in attention. Conclusions: The attentional bias toward happy faces may reflect an active coping attempt by the subclinical participants.     

Preschool Executive Control and Internalizing Symptoms in Elementary School

Depression and anxiety are prevalent and impairing forms of psychopathology in children and adolescents. Deficits in early executive control (EC) may contribute to the development of these problems, but longitudinal studies with rigorous measurement across key developmental periods are limited. The current study examines EC in preschool as a predictor of subsequent depression and anxiety symptoms in elementary school in a community sample (N?=?280). Child participants completed a battery of nine developmentally-appropriate tasks designed to measure major aspects of EC at age 5 years, 3 months. Children later participated in an elementary school follow-up phase, during which they completed validated norm-referenced self-report questionnaires of depression and anxiety symptoms in fourth grade. Results indicate that poorer preschool EC was significantly associated with both greater depression and anxiety symptoms in elementary school, controlling for baseline depression and anxiety symptoms in preschool and other relevant variables. These findings suggest that poor EC may be an important risk factor for the development of internalizing psychopathology in childhood. Given emerging evidence for the modifiability of EC, particularly in preschool, EC promotion interventions may hold promise as a potential target in psychopathology prevention.     

Correspondence between MMPI PTSD measures and clinical diagnosis

Correspondence of the Minnesota Multiphasic Personality Inventory (MMPI) posttraumatic stress disorder (PTSD) subscale and the clinical scale decision rules reported by Keane, Malloy, and Fairbank (1984) with clinical diagnoses of PTSD was measured on a sample of 595 veterans. The measures demonstrated good sensitivity and selectivity, but the false-positive rate was high. It is suggested the MMPI measures be used to rule out, but not to establish, the diagnosis of PTSD. The construct validity of the PTSD subscale was supported by the finding of a higher mean score in combat than noncombat veterans.
