EFFECTS OF SIGNALING INVASIVE PROCEDURES ON A HOSPITALIZED INFANT'S AFFECTIVE BEHAVIORS

We report the effects of using a visual and auditory stimulus signaling impending painful medical procedures versus “safe” periods on the affective behavior of a hospitalized infant. The results of a reversal design suggested that the signaling procedures increased positive behaviors and decreased negative behaviors during both noninvasive and invasive caregiver events.     

On the relationship between Fortier's simultaneous linear prediction and van den Wollenberg's redundancy analysis

The purpose of this note is to show that Van den Wollenberg's method of redundancy analysis is a special case of a simultaneous linear prediction method offered by Fortier.     

The effects of labelling,expert testimony,and information processing mode on juror decisions in SVP civil commitment trials

Expert witnesses offering testimony in sexually violent predator civil commitment trials may use diagnostic labels that are either familiar (e.g. ‘psychopath’) or unfamiliar (e.g. ‘paraphilia’) to jurors. Using predictions based on cognitive experiential self-theory, we explored the influence of testimony type (clinical versus actuarial) and diagnostic label (psychopath versus paraphilia) on jurors motivated to adopt either an experiential processing mode (PM; in which heuristic cues may be strongly relied upon) or an analytic rational PM. Consistent with previous research, our results indicated that when given a psychopathic diagnostic label, mock jurors motivated to process information experientially were more influenced by clinical testimony, whereas mock jurors induced into a rational mode were more influenced by actuarial testimony. However, experientially oriented jurors given a paraphilia diagnostic label did not show the expected influence of clinical expert testimony, and instead were more persuaded by actuarial testimony. These findings are discussed from a judgement and heuristics cues framework. The implications of several procedural suggestions are examined. Copyright © 2009 John Wiley & Sons, Ltd.     

中文故事阅读中预期与前后向推理的关系

通过3项实验,考察了中文故事阅读中前后向推理的差异及其与预期的关系。采用3×2独立设计,以反应时为指标,以较长的语篇为实验材料,分别利用核证法与命名法进行了实验一和二。实验三在实验二的基础上,用2×2独立设计,并根据实验目的修改了实验材料。实验一的结果显示,前向推理和后向推理差异显著;实验二的结果则是前向推理和后向推理无显著差异,而且预期的3个水平在前后向推理上均无显著差异;实验三的结果表明,在预期与前后向推理间距离近和预期句详述的情况下,预期与前后向推理产生了交互作用     

Predicting sports performance from well-being: A mapping of professional athletes’, amateur athletes’ and non-athletes’ positions

IntroductionPrediction of performance and well-being are two essential keys in sports performance.ObjectiveThe study aimed to map different positions regarding the way in which individuals integrated mentally five elements of eudaimonic well-being (relatedness, autonomy, competence, mental vitality and physical vitality) for predicting the degree of performance at the beginning of a match.MethodTwenty-four non-athletes, 44 amateur athletes and 26 professional athletes indicated their prediction of performance in 32 scenarios constructed from the combination of these elements of well-being. Cluster analysis, ANOVAs, and chi-square test have been done.ResultsTwo positions on prediction of performance were found. The first cluster was called “Sometimes Performance Prediction” and the second cluster was named “Seldom Performance Prediction”. The five elements had a positive effect on the prediction of performance. The composition of both clusters was linked to the level of involvement in sport.ConclusionOffering athletes a “well-being environment” may lead to predict the sports performance.     

The temporal dynamics of the perceptual consequences of action-effect prediction

An essential aspect of voluntary action control is the ability to predict the perceptual effects of our actions. Although the influence of action-effect prediction on humans’ behavior and perception is unequivocal, it remains unclear when action-effect prediction is generated by the brain. The present study investigates the dynamics of action effect anticipation by tracing the time course of its perceptual consequences. Participants completed an acquisition phase during which specific actions (left and right key-presses) were associated with specific visual effects (upward and downward dots motion). In the test phase they performed a 2 AFC identification task in which they were required to indicate whether the dots moved upward or downward. To isolate any effects of action-effect prediction on perception, participants were presented with congruent and incongruent dot motion in which the association participants learned in the previous acquisition phase was respected and violated, respectively. Crucially, to assess the temporal dynamics of action prediction, congruent and incongruent stimuli were presented at different intervals before or after action execution. We observed higher sensitivity (d′) to motion discrimination in congruent vs. incongruent trials only when stimuli were presented from about 220 ms before the action to 280 ms after the action. The temporal dynamics of our effect suggest that action-effect prediction modulates perception at later stages of motor preparation.     

Does repeated reading predict reading development over time? A study of children from Grade 3 to 4

The purpose of this study was to investigate whether immediate gains in reading fluency achieved during repeated reading of text can predict long‐term reading development over and above traditional predictors of reading development. Eighty‐one Grade 3 children read texts three times consecutively and were instructed either to read as quickly as possible (speed‐focused repeated reading), or to retell the text afterwards (meaning‐focused repeated reading). Measures of text reading fluency, sentence reading fluency, and text comprehension were administered to the children in Grades 3 and 4 to assess their reading development over time. The results indicate that children's immediate response to repeated reading can contribute to the prediction of their development of reading fluency over time. Even after controlling for individual differences in general cognitive ability, word reading fluency, rapid automatized naming, and vocabulary, the experimental measure with meaning‐focused repeated reading remained a significant predictor.     

Dynamic interplay of depression,perfectionism and self-regulation on procrastination

This study aimed at investigating the intercorrelation among affective, cognitive and behavioural components on procrastination. A total of 402 undergraduate students (115 males, 286 females, 1 not indicated) participated in the study. Students completed the General Procrastination Scale, Depression, Anxiety and Stress Scale, Frost Multidimensional Perfectionism Scale and Self-regulation Inventory. A constructed hypothesised model was tested by utilising path analysis. Overall, the analysis indicated that the model sufficiently explained the data. The findings showed the multicorrelation among the variables, ranging from 14 to 58. Squared multiple correlation coefficients (R²) of procrastination revealed that endogenous and mediator variables explained 33% of the total variance in procrastination. The results demonstrated the importance of affect, cognition and behaviour on problematic delay referred to as procrastination.     

Behavioural Investigative Advice: Assistance to Investigative Decision‐making in Difficult‐to‐detect Murder

This paper considers the role of a Behavioural Investigative Adviser (BIA) in assisting with the decision‐making of a Senior Investigating Officer (SIO) in difficult‐to‐detect murder investigations. It outlines the need for transparent evidence‐based decision‐making from both the SIO and the BIA. The paper then details a piece of relevant, applied research that can assist in this end. The research utilised a pragmatic psychology approach to analyse 312 detected murder cases from the Serious Crime Analysis Section database. Some significant patterns relating what is known about the offence at different stages of an investigation and inferences regarding the offender were found, indicating that certain offence information can lead to some reliable predictions and these can be refined as more information becomes available. However, the findings also indicate that base rate frequencies and a ‘best‐guess’ methodology may be as, if not more, useful than more complex statistical techniques when providing advice to investigations.
