Enhanced Cardiac Perception Is Associated With Increased Susceptibility to Framing Effects

Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The “framing effect” is considered to capture implicit effects of task‐irrelevant emotional stimuli on decision‐making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to the framing effect. Forty volunteers performed a risky‐choice framing task in which the effect of loss versus gain frames on decisions based on identical information was assessed. The results show a positive association between cardiac awareness and the framing effect, accounting for 24% of the variance in the framing effect. These findings demonstrate that good interoceptive skills are linked to poorer performance in risky choices based on ambivalent information when implicit bias is induced by task‐irrelevant emotional information. These findings support a dual process perspective on decision‐making and suggest that interoceptive skills mediate effects of implicit bias on decisions.     

Continuous Access to Competing Stimulation as Intervention for Self-Injurious Skin Picking in a Child with Autism

Children with autism frequently display self-injurious behavior (SIB), but skin picking—a less severe topography of SIB—has not been the focus of much clinical research. The present study evaluated a home-based intervention that was implemented with a 9-year-old girl who had autism and picked her fingers with resulting tissue damage. The intervention allowed the girl to hold and manipulate preferred objects during play and leisure activities. Evaluated in an ABAB reversal design, intervention essentially eliminated skin picking. Clinical and research implications are discussed.     

Psychometric Properties of the Anticipatory Social Behaviours Questionnaire

Relative to other components of Clark and Wells’ (1995) model, anticipatory processing has been understudied, despite research that suggests that anticipatory processing may maintain social anxiety through mechanisms such as increased anxiety, negative memory biases, and other negative consequences. Anticipatory processing has only been examined as a unitary process, with no efforts examining the underlying structure of this process. The purpose of the current study was to examine the factor structure of the Anticipatory Social Behaviours Questionnaire (ASBQ, Hinrichsen and Clark Journal of Behavior Therapy and Experimental Psychiatry, 34, 205–218, 2003) and identify relationships between the measure’s factors and other constructs of social anxiety. Study 1 (N?=?861) used exploratory factor analysis and concluded that a two-factor model (Avoidance and Preparation) was the best conceptualization of anticipatory processing. Study 2 confirmed the two factor model in a separate sample (N?=?485) and demonstrated the superiority of the two-factor model over a unitary model. Results of Study 3 suggested that, with a sample of high-socially-anxious undergraduates (N?=?59), the Avoidance factor was more maladaptive than the Preparation factor. Results are discussed in the context of the anticipatory processing literature and future directions are proposed.     

Job Conditions,Coping and Wellness/Health Outcomes in Spanish Secondary School Teachers

This cross-sectional study is part of EUROTEACH; a project aimed at examining the possible relationships between job conditions and wellness/ health outcomes in teachers from 11 European countries. The Spanish sample consists of 198 (53% female) teachers working in mixed public secondary schools in Alicante. The Job Demand-Control-Social Support (JDCS) model (Johnson and Hall, <citeref rid="bib18">1988</citeref>; Karasek and Theorell, <citeref rid="bib22">1990</citeref>) provides the theoretical framework for the study and specific instruments measuring additional job conditions and coping are applied to investigate these variables in the teaching profession. Moreover, the relationships between the variables are studied to clarify their possible interaction. Results confirm the expected relationship between job conditions and wellness/health effects, and also show the presence of an interaction between coping and the variables in the JDCS model. The need to perform further research on the role of coping, as well as considering other individual variables that might influence teacher occupational stress, is pointed out.     

Measurement tool for preoperative anxiety in young children: The yale preoperative anxiety scale

To develop a preoperative anxiety scale (YPAS) for children undergoing surgery, 21 specific behaviors indicating anxiety were defined within five domains (activity, emotional expressivity, state of arousal, vocalization, and use of adults). A reliability Kappa analysis revealed that inter-observer agreement ranged from .66 to .94, while intra-observer Kappa ranged from .66 to .91. Validity analysis between a Visual Analog Scale and the YPAS revealed an r of .59 for entering the operating room. Multiserial analysis comparing the YPAS to the Vernon Anxiety Scale ranged from .61 to .64. Showing good to excellent observer reliability and validity, the YPAS proves to be an appropriate tool for studying children's responses in preoperative settings. As such, the new assessment instrument should be of interest to clinical and research neuropsychologists who need to assess a child's anxiety level prior to the undertaking of a given surgical procedure.     

Prenatal cocaine exposure and neurobehavioral development: How subjects lost to follow-up bias study results

Ninety-four prenatally cocaine-exposed and 50 non-cocaine-exposed infants were enrolled at birth and seen at 3,6, and 12 months. Applying a recently developed model (Cicchetti&Nelson, 1994) produced four independent groups: those infants assessed at birth only (n=61), those returning for at least one (n=29) or two (n=15) assessments after birth, and those returning for all three (n=35). Among those infants having all follow-up assessments, cocaine-exposed infants showed significantly lower psychomotor performance on the Bayley Scales of Infant Development (BSID) than did non-exposed infants. Results approached statistical significance for mental development. Except for birthweight (cocaine-exposed infants weighed significantly less), none of a wide range of maternal, perinatal, or neurobehavioral demographic variables biased study results or the generalization of findings to the total sample from those who returned for all visits.     

The impact of cognitive control on children’s goal monitoring in a time-based prospective memory task

The present study investigated whether developmental changes in cognitive control may underlie improvements of time-based prospective memory. Five-, 7-, 9-, and 11-year-olds (N = 166) completed a driving simulation task (ongoing task) in which they had to refuel their vehicle at specific points in time (PM task). The availability of cognitive control resources was experimentally manipulated by imposing a secondary task that required divided attention. Children completed the driving simulation task both in a full-attention condition and a divided-attention condition where they had to carry out a secondary task. Results revealed that older children performed better than younger children on the ongoing task and PM task. Children performed worse on the ongoing and PM tasks in the divided-attention condition compared to the full-attention condition. With respect to time monitoring in the final interval prior to the PM target, divided attention interacted with age such that older children’s time monitoring was more negatively affected by the secondary task compared to younger children. Results are discussed in terms of developmental shifts from reactive to proactive monitoring strategies.     

High-pressure phase transition and lattice dynamics of rock-salt and FeSi-type phases of MgS

A phase transition of MgS under high pressure is investigated using a first-principles method. It is found from energy-volume calculations that the rock-salt (B1) phase of MgS transforms into a FeSi-type (B28) phase at 143?GPa. The calculated ground-state parameters in the B1 phase are in excellent agreement with available experimental and theoretical data. Ab initio phonon calculations are also performed to investigate the structural behaviour of MgS under high pressure. An unstable transverse acoustic mode and a phase transition from B1 to B28 phase at ~143.7?GPa driven by this soft mode are predicted. The B28 structure of MgS is stable up to 350?GPa according to lattice dynamics calculations.     

Analysis of intrinsic diffusivities in multicomponent alloys

In this letter we consider the intrinsic diffusivities in a multicomponent random alloy in terms of the ratios of atom-vacancy exchange frequencies. Using the exact sum rule due to Moleko and Allnatt, which relates phenomenological coefficients in the multicomponent random alloy, we deduce an exact relationship between the intrinsic diffusivities and the ratios of the exchange frequencies. We exemplify the finding with a consideration of binary and ternary random alloys. We show that the new relationship should be robust enough for employment in multicomponent alloys showing non-ideality.     

Distortion analysis of magnetic excitation – a novel method for non-destructive evaluation of depth of surface-hardening in ferritic steels

The influence of ferritic steel samples with different case-depths on the distortion behaviour of magnetic excitation voltage has been investigated. The systematic changes in the height and position of the peak and the trough on the ((dV_E/dt) vs. V_T) profile (distortion analysis of the magnetic excitation, DAME profile) reflect the difference in the magnetization process and hence the effect of distortion of V_E in samples with different case-depths. This study shows the potential of this simple DAME method for evaluation of ferromagnetic steel components.
