Increasing compliance with medical examination requests directed to children with autism: effects of a high-probability request procedure

The purpose of this study was to evaluate the effectiveness of a high-probability (high-p) request sequence as a means of increasing compliance with medical examination tasks. Participants were children who had been diagnosed with autism and who exhibited noncompliance during general medical examinations. The inclusion of the high-p request sequence effectively increased compliance with medical examination tasks. In addition, the procedure was efficient, could be implemented by parents and medical professionals, and did not involve aversive procedures.     

Integrating personality, daily life events and emotion: Role of anxiety and positive affect in emotion regulation dynamics

We investigated the roles of anxiety and positive affect in emotion regulation, looking simultaneously at personality, daily life events, and affects. We hypothesized that individual differences in the temporal dynamics of affective experience related to trait anxiety would manifest themselves both in affective responsiveness to life events and in homeostatic regulatory forces. Data were collected from 49 adults, who rated their affective state three times a day over a 40-day period. Data were analyzed using a dynamical system model and graphical representations in the form of vector fields. Results showed that anxiety chiefly interacted with home base (attractor) positions as a function of life events. It also influenced the shape of positive affectivity trajectories in response to negative events.     

Genetic testing for hereditary cancer: effects of alexithymia and coping strategies on variations in anxiety before and after result disclosure

This study assessed the impact of the results of genetic testing for hereditary cancer from a multifactorial health psychology perspective, considering that emotional expression plays a key role in psychological adjustment. Measures of dispositional and transactional coping strategies, anxiety and alexithymia were filled out by 77 participants in a longitudinal study design. Statistical analyses were performed using general linear models and partial least squares path modelling, low-constraint methods that are particularly useful in the behavioural sciences. While anxiety levels prior to the result announcement were predictive of the distress experienced by noncarriers, considerable variability was observed for mutation carriers. Some subjects who had lower anxiety levels before the test displayed greater anxiety afterwards, but others seemed to anticipate the distress they would experience with the result that they showed a decrease in anxiety. The mutation carriers behaved as though their adaptive functioning were reshaped by the test result, independent of their disposition and previous emotional state, except in the case of alexithymia. Difficulty expressing emotions prior to genetic testing contributed to a similar difficulty after receiving the result, adding to the latter's emotional impact by promoting emotion-focused coping strategies and increasing distress.     

Linear mapping of numbers onto space requires attention

Mapping of number onto space is fundamental to mathematics and measurement. Previous research suggests that while typical adults with mathematical schooling map numbers veridically onto a linear scale, pre-school children and adults without formal mathematics training, as well as individuals with dyscalculia, show strong compressive, logarithmic-like non-linearities when mapping both symbolic and non-symbolic numbers onto the numberline. Here we show that the use of the linear scale is dependent on attentional resources. We asked typical adults to position clouds of dots on a numberline of various lengths. In agreement with previous research, they did so veridically under normal conditions, but when asked to perform a concurrent attentionally-demanding conjunction task, the mapping followed a compressive, non-linear function. We model the non-linearity both by the commonly assumed logarithmic transform, and also with a Bayesian model of central tendency. These results suggest that veridical representation numerosity requires attentional mechanisms.     

Cheating the Lie Detector: Faking in the Autobiographical Implicit Association Test

ABSTRACT— The autobiographical Implicit Association Test (aIAT) was recently introduced in this journal as a new and promising lie-detection tool. The initial report found 91% accuracy in determining which of two autobiographical events was true. It was suggested that the aIAT, unlike other lie-detection tests, is resistant to faking. We investigated whether participants can strategically alter their performance on the aIAT. Experiment 1 showed that participants guilty of a mock theft were able to obtain an innocent test outcome. Two additional experiments showed that guilty participants can fake the aIAT without prior experience with the aIAT and when a response deadline is imposed. The aIAT is subject to the same shortcomings as other lie-detection tests.     

Lexical decomposition of complex Kanji characters in Japanese readers

Summary The study investigates the question whether during recognition of a complex Kanji character readers also access the meaning of opaque components of the character. The experiment used a speeded semantic-categorization task of two characters, in which readers were requested to decide whether two characters represented words related in meaning or not. The control pairs consisted of (a) graphically similar, but semantically unrelated, characters, and (b) a simple character and a complex character, of which the simple character was a component (part-whole relation), the two characters being again semantically unrelated. The critical pairs consisted of two characters unrelated in meaning, one of which contained an opaque component element related in meaning to the other character. A corresponding trial with English and its alphabetic system would be to ask a subject to decide whether boycott is related in meaning to girl or not. In this condition the subject is expected to give a No response, but if the pseudocomponent boy is activated, interference could occur. (If boy is recovered during recognition of the pseudocompound boycott, the appropriate No response for boycott-girl could become more difficult to take.) The result of the experiment indicated interference in all three conditions (graphically similar characters, part-whole related characters, and opaque-component related characters. Thus, in an analogous task with alphabetic material, it would be more difficult to say No about the existence of a semantic relation between (a) tree and free, (b) boy and boycott, and (c) boycott and girl. The last result can be interpreted as offering evidence for the activation of the opaque component upon recognition of the complex character.This account is somewhat oversimplified. It is not always easy to determine which is a radical in a complex character. A higher radical can in fact be a combination of a lower radical with the addition of one or more strokes.     

Anxiety,depression, and the suicidal spectrum: a latent class analysis of overlapping and distinctive features

ABSTRACT

Anxiety and depression diagnoses are associated with suicidal thoughts and behaviours. However, a categorical understanding of these associations limits insight into identifying dimensional mechanisms of suicide risk. This study investigated anxious and depressive features through a lens of suicide risk, independent of diagnosis. Latent class analysis of 97 depression, anxiety, and suicidality-related items among 616 psychiatric outpatients indicated a 3-class solution, specifically: (1) a higher suicide-risk class uniquely differentiated from both other classes by high reported levels of depression and anxious arousal; (2) a lower suicide-risk class that reported levels of anxiety sensitivity and generalised worry comparable to Class 1, but lower levels of depression and anxious arousal; and (3) a low to non-suicidal class that reported relatively low levels across all depression and anxiety measures. Discriminants of the higher suicide-risk class included borderline personality disorder; report of worthlessness, crying, and sadness; higher levels of anxious arousal and negative affect; and lower levels of positive affect. Depression and anxiety diagnoses were not discriminant between higher and lower suicide risk classes. This transdiagnostic and dimensional approach to understanding the suicidal spectrum contrasts with treating it as a depressive symptom, and illustrates the advantages of a tripartite model for conceptualising suicide risk.
