An evaluation of counselling and rehabilitation courses for Chronic Fatigue Syndrome

The aim of the current study was to evaluate the services offered by Action for ME to sufferers of Chronic Fatigue Syndrome using measures developed and validated in previous research. Preliminary studies had suggested that clients attending rehabilitation residential courses were benefiting from the service. A further, more in‐depth evaluation process with a greater number of health‐related outcome measures was warranted. In addition, assessment was widened to include other services offered to sufferers of the illness. Data relating to the usefulness and success of the services (rated by the clients) were also collected. Data from client volunteers were collected at baseline (that is, before intervention) and approximately six months later. Quantitative comparative analyses were conducted using within‐group comparisons to assess any improvements in scores at six‐month follow‐up from baseline. Fifty‐six participants completed wide‐ranging questionnaires assessing illness history, psychopathology, psychosocial factors and health and well‐being. Data relating to improvements in illness status and acceptability of treatment were also collected by means of global outcome measures. Both the counselling and residential groups showed improvements in many areas assessed at follow‐up. Most importantly, improvements were indicated in areas such as fatigue and the levels of disability suffered by patients. In addition, there were significant improvements in ratings of mood, anxiety, depression and physical symptoms. Overall, clients reported satisfaction with the care received and most found the services useful. All of the participants who completed the evaluation stated that they would recommend Action for ME services to fellow sufferers. The outcome of the current study is encouraging. The data presented provides evidence of the high level of support and advice Action for ME offers to sufferers of this illness. Furthermore, measurable improvements in scores relating to illness status were accompanied by improvements in mental health and psychosocial variables in the patient group.     

Judgments of emotion from spontaneous facial expressions of New Guineans

The claim that specific discrete emotions can be universally recognized from human facial expressions is based mainly on the study of expressions that were posed. The current study (N=50) examined recognition of emotion from 20 spontaneous expressions from Papua New Guinea photographed, coded, and labeled by P. Ekman (1980). For the 16 faces with a single predicted label, endorsement of that label ranged from 4.2% to 45.8% (mean 24.2%). For 4 faces with 2 predicted labels (blends), endorsement of one or the other ranged from 6.3% to 66.6% (mean 38.8%). Of the 24 labels Ekman predicted, 11 were endorsed at an above-chance level, and 13 were not. Spontaneous expressions do not achieve the level of recognition achieved by posed expressions.     

Anxiety and sensitivity to gaze direction in emotionally expressive faces

This study investigated the role of neutral, happy, fearful, and angry facial expressions in enhancing orienting to the direction of eye gaze. Photographs of faces with either direct or averted gaze were presented. A target letter (T or L) appeared unpredictably to the left or the right of the face, either 300 ms or 700 ms after gaze direction changed. Response times were faster in congruent conditions (i.e., when the eyes gazed toward the target) relative to incongruent conditions (when the eyes gazed away from the target letter). Facial expression did influence reaction times, but these effects were qualified by individual differences in self-reported anxiety. High trait-anxious participants showed an enhanced orienting to the eye gaze of faces with fearful expressions relative to all other expressions. In contrast, when the eyes stared straight ahead, trait anxiety was associated with slower responding when the facial expressions depicted anger. Thus, in anxiety-prone people attention is more likely to be held by an expression of anger, whereas attention is guided more potently by fearful facial expressions.     

From marine ecology to crime analysis: Improving the detection of serial sexual offences using a taxonomic similarity measure

Jaccard has been the choice similarity metric in ecology and forensic psychology for comparison of sites or offences, by species or behaviour. This paper applies a more powerful hierarchical measure—taxonomic similarity (Δ_s), recently developed in marine ecology—to the task of behaviourally linking serial crime. Forensic case linkage attempts to identify behaviourally similar offences committed by the same unknown perpetrator (called linked offences). Δ_s considers progressively higher‐level taxa, such that two sites show some similarity even without shared species. We apply this index by analysing 55 specific offence behaviours classified hierarchically. The behaviours are taken from 16 sexual offences by seven juveniles where each offender committed two or more offences. We demonstrate that both Jaccard and Δ_s show linked offences to be significantly more similar than unlinked offences. With up to 20% of the specific behaviours removed in simulations, Δ_s is equally or more effective at distinguishing linked offences than where Jaccard uses a full data set. Moreover, Δ_s retains significant difference between linked and unlinked pairs, with up to 50% of the specific behaviours removed. As police decision‐making often depends upon incomplete data, Δ_s has clear advantages and its application may extend to other crime types. Copyright © 2007 John Wiley & Sons, Ltd.     

On the Idea that God is Continuously Re-creating the Universe

Many theists believe that God is continuously acting to sustain the universe in existence. One way of understanding this act of sustenance is to see God as actually creating the universe anew at each moment. This paper argues against the coherence of this view by drawing out some of its consequences. I argue that the re-creationist must deny the causal efficacy of created f things, as well as the identity of things across time. Most problematically, I argue that re-creationism ultimately denies the reality of time itself.

Attitude learning through exploration: advice and strategy appraisals

Processes of attitude learning were investigated through a game requiring discrimination between good and bad objects, where feedback about object valence (involving gain or loss) is contingent on approach. Previous research demonstrates a preponderance of false‐negative errors, with some good objects (‘learning asymmetry’) and most novel objects (‘generalization asymmetry’) being judged as bad, but provides no direct evidence concerning how participants appraise alternative strategies and their own performance. To compare alternative strategies, participants received advice, supposedly from a previous participant, that most objects were bad and should be avoided, or good and should be approached. Learning and generalization asymmetries were replicated, especially among participants who followed the former (risk‐averse) advice. Additionally, participants' evaluations of their own game strategy were inversely related to amount of negative feedback (the number of bad objects approached), but unrelated to positive feedback (from good objects approached), pointing to the salience of negative information for self‐appraisals.

Environmental Correlates of Gambling Behavior in Urban Adolescents

The present study considered the relation between adolescent gambling behavior and the perceived environment, the component of Jessor and Jessor’s (1977) Problem Behavior Theory that assesses the ways that adolescents perceive the attitudes and behaviors of parents and peers. The predominantly African-American sample included 188 sophomores from two urban public high schools. Using the South Oaks Gambling Screen-Revised for Adolescents to assess gambling risk, rates of both at-risk (20.7%) and problem (12.8%) gambling were found to be high. Boys displayed more gambling problems than did girls. The perceived environment accounted for significant variance in gambling problems and frequency, with proximal components displaying stronger relationships than distal components. Perceiving parent gambling and friend models for problem behavior were positively correlated with gambling problems, and friend models were positively related to gambling frequency. Among girls, family support was positively related to gambling problems. Among boys, this relation was negative. The authors Emerson M. Wickwire, Jr. James P. Whelan, and Andrew W. Meyers are members of The Institute for Gambling Education and Research, Department of Psychology, The University of Memphis, Memphis, TN. The primary research interest of this group is the prevention and treatment of gambling related problems. David M.

Words, hemispheres, and processing mechanisms: A response to Marsolek and Deason (2007)

Ellis, Ansorge and Lavidor (2007) [Ellis, A.W., Ansorge, L., & Lavidor, M. (2007). Words, hemispheres, and dissociable subsystems: The effects of exposure duration, case alternation, priming and continuity of form on word recognition in the left and right visual fields. Brain and Language, 103, 292–303.] presented three experiments investigating the effects of exposure duration and format (normal vs mixed or alternating case) on the recognition of words presented in the left and right visual fields. The experiments were conducted within the framework of ‘dissociable neural subsystems theory’ developed by Marsolek and colleagues. Marsolek and Deason (2007) [Marsolek, C.J. & Deason, R.G. (2007). Hemispheric asymmetries in visual word-form processing: Progress, conflict, and evaluating theories. Brain and Language, 103, 304–307.] offer some reflections on our paper, including alternative interpretations of some of our findings. We respond to those reflections in this reply.
