Radial bisection of words and lines in right‐brain‐damaged patients with spatial neglect

The bisection of lines positioned radially (with the two ends of the line close and far, with respect to the participant's body) has been less investigated than that of lines placed horizontally (with their two ends left and right, with respect to the body's midsagittal plane). In horizontal bisection, patients with left neglect typically show a rightward bias for both lines and words, greater with longer stimuli. As for radial bisection, available data indicate that neurologically unimpaired participants make a distal error, while results from right‐brain‐damaged patients with left spatial neglect are contradictory. We investigated the bisection of radially oriented words, with the prediction that, during bisection, linguistic material would be recoded to its canonical left‐to‐right format in reading, with the performance of neglect patients being similar to that for horizontal words. Thirteen right‐brain‐damaged patients (seven with left spatial neglect) and fourteen healthy controls were asked to manually bisect 40 radial and 40 horizontal words (5–10 letters), and 80 lines, 40 radial and 40 horizontal, of comparable length. Right‐brain‐damaged patients with spatial neglect exhibited a proximal bias in the bisection of short radial words, with the proximal part corresponding to the final right part of horizontally oriented words. This proximal error was not found in patients without neglect and healthy controls. For bisection, short radial words may be recoded to the canonical orthographic horizontal format, unveiling the impact of left neglect on radially oriented stimuli.     

Response inhibition in the parametric go/no-go task and its relation to impulsivity and subclinical psychopathy

The current study utilizes the parametric go/no-go task (PGNG), a task that examines changes in inhibitory performance as executive function load increases, to examine the link between psychopathic traits, impulsivity, and response inhibition in a cohort of healthy participants. The results show that as executive function load increased, inhibitory ability decreased. High scores on the Cognitive Complexity subscale of the Barratt Impulsivity Scale (BIS–11) predict poor inhibitory ability in the PGNG. Similarly, high scores on the Psychopathy Personality Inventory–Revised (PPI–R) Blame Externalization subscale predict response inhibition deficits in the PGNG, which loads more on the executive functions than the standard go/no-go task. The remaining BIS–11 as well as PPI–R subscales did not interact with inhibitory performance in the PGNG highlighting the specificity of associations between aspects of personality and impulsivity with inhibitory performance as cognitive load is increased. These data point towards the sensitivity of the PGNG in studying response inhibition in the context of highly impulsive populations and its utility as a measure of impulsivity.     

Relating lab to life: Decrements in attention over time predict math productivity among children with ADHD

A child’s ability to sustain attention over time (AOT) is critical in attention-deficit/hyperactivity disorder (ADHD), yet no prior work has examined the extent to which a child’s decrement in AOT on laboratory tasks relates to clinically-relevant behavior. The goal of this study is to provide initial evidence for the criterion validity of laboratory assessments of AOT. A total of 20 children with ADHD (7–12 years of age) who were enrolled in a summer treatment program completed two lab attention tasks (a continuous performance task and a self-paced choice discrimination task) and math seatwork. Analyses focused on relations between attention task parameters and math productivity. Individual differences in overall attention (OA) measures (averaged across time) accounted for 23% of the variance in math productivity, supporting the criterion validity of lab measures of attention. The criterion validity was enhanced by consideration of changes in AOT. Performance on all laboratory attention measures deteriorated as time-on-task increased, and individual differences in the decrement in AOT accounted for 40% of the variance in math productivity. The only variable to uniquely predict math productivity was from the self-paced choice discrimination task. This study suggests that attention tasks in the lab do predict a clinically-relevant target behavior in children with ADHD, supporting their use as a means to study attention processes in a controlled environment. Furthermore, this prediction is improved when attention is examined as a function of time-on-task and when the attentional demands are consistent between lab and life contexts.     

Ethical Guidelines for Mass Trauma and Complex Humanitarian Emergencies

Issues pertaining to trauma, especially mass trauma and complex humanitarian emergencies, are explored through the lens of ethical counseling guidelines. In mass trauma, particular attention must be paid to the experiences of both survivors and counselors to enhance understanding of ethical best practices and to emphasize the importance of contextual factors in framing effective responses to trauma and humanitarian crises. Recommendations regarding ethical guidelines for counseling practice, clinical involvement, and training are offered.     

The role of fear in predicting sexually transmitted infection screening

Objective: This study assessed the extent to which social-cognitive factors (attitude, subjective norm and perceived control) and the fear of a positive test result predict sexually transmitted infection (STI) screening intentions and subsequent behaviour.

Design: Study 1 (N = 85) used a longitudinal design to assess the factors that predict STI screening intention and future screening behaviour measured one month later at Time 2. Study 2 (N = 102) used an experimental design to determine whether the relationship between fear and screening varied depending on whether STI or HIV screening was being assessed both before and after controlling for social-cognitive factors.

Main Outcome Measures: Across the studies the outcome measures were sexual health screening.

Results: In both studies, the fear of having an STI positively predicted STI screening intention. In Study 1, fear, but not the social-cognitive factors, also predicted subsequent STI screening behaviour. In Study 2, the fear of having HIV did not predict HIV screening intention, but attitude negatively and response efficacy positively predicted screening intention.

Conclusion: This study highlights the importance of considering the nature of the health condition when assessing the role of fear on health promotion.     

Recalcitrant Fears of Death

According to what I will refer to as judgmentalist approaches to the fear of death (JFD), the fear of death conforms to the structure implied by judgmentalist theories of emotion. JFD holds that fears of death are constituted in part by evaluative judgments or beliefs about one’s own death. Although many philosophers endorse JFD (explicitly or implicitly), there is good reason to believe that it may be problematic. For, there is a troubling (and, for the purposes of this discussion, rather interesting) objection to judgmentalist theories of emotion; if judgmentalism is false, then so too is JFD. In brief, the worry with judgmentalist theories is this: it is sometimes the case that one has an emotion, but holds a belief (or beliefs) that is in tension with the emotion. For example, I sometimes fear flying despite the fact that I believe flying is not dangerous. Emotions of this sort are often referred to as recalcitrant emotions, and they are widely thought to pose a serious challenge to judgmentalist theories. In this paper, I consider an objection to JFD based on the existence of recalcitrant bouts of the fear of death. I include in this discussion an Epicurean-inspired solution to the problem of emotional recalcitrance. Although I argue this solution may be ultimately unsuccessful, I believe it is still worth considering. For, in most discussions of the problem of emotional recalcitrance, philosophers abandon judgmentalism in favour of some other theory of emotion. The Epicurean-inspired solution I discuss in this paper, however, may allow one to retain one’s commitment to judgmentalism.     

Fear of crime and community concerns: Mediating effect of risk and pragmatic fear

This study investigates the relationship between community concerns (i.e., perceived crime, incivilities, and infrastructure) and fear of crime (FOC) while examining the mediating role of risk of victimisation and pragmatic fear. Gender and ethnic differences were also explored. Data were collected using a proportionate multistage random sample of 3,003 participants from a southern Caribbean island in 2015. The following self‐reported measures were used: risk of victimisation and FOC scales, a general (noncrime) fear scale measuring pragmatic fear, and a community concern scale. Data were analysed using path analysis, Sobel tests, and multiple group analysis. Findings revealed that perceived crime and incivilities significantly predicted FOC, whereas infrastructure was insignificant as a direct predictor. Females had higher FOC, and among ethnic groups, Indo‐Trinidadians had the highest FOC than Afro‐Trinidadians and Mixed participants. Risk of victimisation and pragmatic fear had significant mediating effects on community concerns and FOC. Findings are discussed in the context of the social psychology of social disorganisation and previous research.     

Group‐analytic network process for balancing stakeholder views on fire protection of steel‐framed buildings

To select appropriate fire protection options for buildings during their design stage, economic, safety, environmental, and societal criteria need to be accounted for. The divergent and sometimes conflictual desires from different fire design stakeholders involved in the process present a multicriteria decision problem. Design decision criteria and fire protection options can be interdependent, and so there is a need to manage these desires with an advanced decision analysis technique, thereby reducing uncertainties in the complex decision‐making process. The aim of this paper is to use the weighted/geometric mean method‐analytic network process (W/GMM‐ANP) to balance the opinions of fire design stakeholders extracted from 42 structured stakeholder interviews on selecting the most suitable fire protection option for buildings constructed of steel frames. Different categories of interdependent decision elements were developed from 22 design decision criteria and 5 proposed fire protection options to produce a network of decision clusters for multicriteria decision analysis. In the synthesis and ranking of fire protection options, the W/GMM‐ANP accounted for the multiple interdependencies of weighted and unweighted stakeholder desires and managed the complexity of the decision‐making problem. The technique is proposed for approaching suitable group decisions in structural fire design of steel‐framed buildings as well as other performance‐based engineering decision making that may involve multidisciplinary stakeholders.     

高低情感开放性者概率内隐序列学习进程差异

大五人格情感开放性子量表(openness/feeling)能否预测内隐序列学习的问题存在争议。本研究采用概率性内隐序列学习范式, 比较高低情感开放性者在各反应刺激间隔(response stimulus interval, 即RSI)的差异。发现：(1) RSI = 0 ms和250 ms, 高分组在转移组块后习得高概率序列, RSI = 500 ms及以上在其之前习得; 所有RSI点低分组都在其之前习得。每个RSI点只有高分组习得低概率序列。证明随RSI增加两者内隐进程有本质差异, openness/feeling子量表可预测内隐序列学习个体差异。(2)低概率序列可作为测量概率性内隐序列学习及个体差异的新指标, 经典转移组块、再认、生成任务的测量效果却十分有限。
