A study of the effects of cranial electrical stimulation on attention and concentration.

There have been several anecdotal accounts that cranial electrical stimulation (CES) enhances attention and the ability to learn new tasks in a normal population, but only one published investigation confirms that CES improves attention using the Alpha Stim CES (Madden and Kirsch, 1987). The purpose of this study was to corroborate the findings of Madden and Kirsch, using more precise measures of attention, such as a Continuous Performance Test (CPT). A pretest and posttest CPT was given to two groups using the LISS CES device. The control group consisted of twenty-one subjects who received the placebo treatment. The experimental group of thirty-one subjects received twenty minutes of CES. Four measures of the CPT show significant gains in attention: Number of Hits, p =.010 Hit RT ISI Change, p =.016, Risk Taking, p =.055; and Attentiveness, p =.054. Based on subjects who demonstrated improvement by one standard deviation on two different measures of the CPT, thirty-one percent of the experimental group improved versus four percent of the control group. The use of CES as a method of increasing attention is a promising area that requires further investigation.     

Cerebellum and processing of negative facial emotions: Cerebellar transcranial DC stimulation specifically enhances the emotional recognition of facial anger and sadness

Some evidence suggests that the cerebellum participates in the complex network processing emotional facial expression. To evaluate the role of the cerebellum in recognising facial expressions we delivered transcranial direct current stimulation (tDCS) over the cerebellum and prefrontal cortex. A facial emotion recognition task was administered to 21 healthy subjects before and after cerebellar tDCS; we also tested subjects with a visual attention task and a visual analogue scale (VAS) for mood. Anodal and cathodal cerebellar tDCS both significantly enhanced sensory processing in response to negative facial expressions (anodal tDCS, p=.0021; cathodal tDCS, p=.018), but left positive emotion and neutral facial expressions unchanged (p>.05). tDCS over the right prefrontal cortex left facial expressions of both negative and positive emotion unchanged. These findings suggest that the cerebellum is specifically involved in processing facial expressions of negative emotion.     

Psychotherapeutic Interventions for Symptom Reduction in Veterans With PTSD: An Observational Study in a Residential Clinical Setting

Cognitive processing therapy (CPT) and eye movement desensitization and reprocessing (EMDR) therapy were compared for veterans in a posttraumatic stress disorder (PTSD) residential program (N = 51) who received individual EMDR and group CPT, individual CPT and group CPT, or trauma group exposure (TGE) therapy. Analyses revealed an overall significant difference on posttest measures of the PTSD Checklist for individual EMDR/group CPT and individual CPT/group CPT when compared to TGE, with no significant difference found between EMDR and CPT. Depression scores were significantly decreased between pre- and posttest for patients who received individual EMDR/group CPT. Results support EMDR and CPT as clinically effective and complementary treatments in residential PTSD treatment programs.     

A meta-analytic review of cognitive processing therapy for adults with posttraumatic stress disorder

Numerous studies have demonstrated the efficacy of cognitive processing therapy (CPT) for treating posttraumatic stress disorder (PTSD). Two prior meta-analyses of studies are available but used approaches that limit conclusions that can be drawn regarding the impact of CPT on PTSD outcomes. The current meta-analysis reviewed outcomes of trials that tested the efficacy of CPT for PTSD in adults and evaluated potential moderators of outcomes. All published trials comparing CPT against an inactive control condition (i.e. psychological placebo or wait-list) or other active treatment for PTSD in adults were included, resulting in 11 studies with a total of 1130 participants. CPT outperformed inactive control conditions on PTSD outcome measures at posttreatment (mean Hedges’ g = 1.24) and follow-up (mean Hedges’ g = 0.90). The average CPT-treated participant fared better than 89% of those in inactive control conditions at posttreatment and 82% at follow-up. Results also showed that CPT outperformed inactive control conditions on non-PTSD outcome measures at posttreatment and follow-up and that CPT outperformed other active treatments at posttreatment but not at follow-up. Effect sizes of CPT on PTSD symptoms were not significantly moderated by participant age, number of treatment sessions, total sample size, length of follow-up, or group versus individual treatment; but, older studies had larger effect sizes and percent female sex moderated the effect of CPT on non-PTSD outcomes. These meta-analytic findings indicate that CPT is an effective PTSD treatment with lasting benefits across a range of outcomes.     

Rating Level and Accuracy as a Function of Rater Personality

We investigated the predictability of rating level and two measures of rating accuracy from rater Agreeableness (A) and Conscientiousness (C) scores of the Five Factor Model. One hundred and twenty‐six students made peer ratings after participating in several group exercises under conditions designed to emulate the modal peer rating system in which raters had low accountability for their ratings. Scores were correlated with average rating level (r=.18, p<.05) and both measures of rating accuracy (p<.05) and C scores were correlated with rating level (?.20, p<.05) and both measures of rating accuracy (p<.05). As suggested by Bernardin, Villanova, and Cooke (Journal of Applied Psychology, 85, 232–236, 2000), raters who were both more agreeable and less conscientious made the most lenient and least accurate ratings. Contrary to Yun, Donahue, Dudley, and McFarland (International Journal of Selection and Assessment, 13, 97–107, 2005), more agreeable raters also tended to rate the least effective performers more leniently than did other raters.     

Reliability of heterosocial skills measurement with sex offenders

The heterosocial skills of 79 sex offenders were assessed using two self-report inventories, the Social Anxiety and Distress Scale (SAD) and the S-R Inventory of Anxiousness (SRI). In addition, staff members rated the offenders on modified versions of the SAD and the Heterosocial Skills Behavior Checklist for Males (HSB). Twenty-one offenders were also videotaped during a brief interaction with a female confederate. The tapes were rated using the HSB. All ratings and videotapings were conducted twice within a two-week period. The two self-report scales showed good test-retest reliability (r=.88) and correlatedr=.63 with each other. However, the SAD correlated significantly with the Crowne-Marlowe Social Desirability Scale and showed significant change from first to second administrations. The SRI showed less reactivity to social desirability and changed less over time. The staff ratings showed higher test-retest (r=.72–.76) than interrater (r=.36–.43) reliability. They correlatedr=–.56 with each other and did not show a significant relationship to the Crowne-Marlowe. However, both staff-ratings changed significantly from test to retest. Inspection of correlations between staff and self-report measures indicated that these instruments may be strongly affected by rater variance. Different measures completed by the same person correlated higher than the same measure completed by different persons. The HSB showed high levels of interrater agreement (90–100%) and split-half reliability (r=.95–.97). However, test-retest reliability was poor for the overall score and for the category measuring form of conversation. Categories measuring voice and affect were moderately reliable over time (r=.53–.74). However, the voice category scores changed substantially from first to second videotaping. On almost all measures used in this study, the sex offenders' scores were similar to those derived from normal populations. Only the category measuring affect on the HSB seemed to differentiate this group from normals.     

INCREASING EXTENDED CARE FACILITY RESIDENTS' ATTENDANCE AT RECREATIONAL ACTIVITIES WITH CONVENIENT LOCATIONS AND PERSONAL INVITATIONS1

Residents of extended care facilities generally exhibit a low level of attendance at recreational and therapeutic activities. Spatial arrangement of rooms, prompting, snacks, and small prizes have been suggested as factors that affect attendance. The present study examined the effects of an extensive system of prompts and the location of activity areas on the attendance of residents at a variety of activities. Twenty-six subjects were randomly selected from the ambulatory population of the facility. The first time each subject entered the activity room during the first 6 min of an activity session their name was recorded. Reliability measures were taken at 10 sessions, with a 95% mean agreement between observers. The variables examined were the amount of individualization of subjects (experimental group I: names announced versus experimental group 2: names not announced), room location (central or peripheral), use of names in announcements (activity only versus activity and group I names), and mode of announcement (PA system only versus PA system and in-person). A counter-balanced group design with repeated measures was used, with a randomly determined order of application of experimental treatments. An analysis of variance split plot 2.222 (Kirk, R. E. Experimental Design: Procedures for the Behavioral Science. Belmont, Ca.: Brooks-Cole, 1968.) of the level of subject attendance yielded significant main effects for room location, F(1, 24) = 5.47, p < 0.05, and type of announcement, F(1, 24) = 9.10, p < 0.01, and significant interactions for Individualization × Use of Names in Announcements, F(1, 24) = 5.57, p < 0.05, and Room Location × Mode of Announcement, F(1, 24) = 7.90, p < 0.01. The results indicate that using a centrally located room and announcement of resident names increases attendance at a variety of activities. The increased social and environmental interaction generated by activity attendance has potential therapeutic benefits for the residents involved. Furthermore, the kind of information reported here and by others should be taken into consideration by planners of a variety of group living facilities, ranging from nursing homes to residential treatment cottages.     

Does the Conners' Continuous Performance Test Aid in ADHD Diagnosis?

The performance of clinic-referred children aged 6–11 (N = 100) was examined using the Conners' Continuous Performance Test (CPT) and measures of auditory attention (Auditory Continuous Performance Test; ACPT), phonological awareness, visual processing speed, and visual-motor competence. The Conners' CPT overall index was unrelated to measures of visual processing speed or visual-motor competence. Although the Conners' CPT converged with the ACPT, the latter demonstrated age and order effects. Significant variance in Conners' CPT parameters was predicted by phonological awareness measures, suggesting that Reading Disordered (RD) children could be false positives on the Conners' CPT. The Conners' CPT overall index, phonological awareness, and visual-motor measures were submitted to a 2×2 MANCOVA (ADHD vs. RD, covarying for age and socieoeconomic status): a main effect for RD status was found. Children with ADHD did not have higher Conners' CPT scores than did clinical controls; however, children with Reading Disorders did. Phonological measures distinguished RD children from ADHD children and other clinical controls. ADHD children who failed the Conners' CPT were rated by teachers as more hyperactive. Despite the strengths of the Conners' CPT, its utility for differential diagnosis of ADHD is questioned.     

AULA virtual reality test as an attention measure: Convergent validity with Conners’ Continuous Performance Test

The majority of neuropsychological tests used to evaluate attention processes in children lack ecological validity. The AULA Nesplora (AULA) is a continuous performance test, developed in a virtual setting, very similar to a school classroom. The aim of the present study is to analyze the convergent validity between the AULA and the Continuous Performance Test (CPT) of Conners. The AULA and CPT were administered correlatively to 57 children, aged 6–16 years (26.3% female) with average cognitive ability (IQ mean = 100.56, SD = 10.38) who had a diagnosis of attention deficit/hyperactivity disorder (ADHD) according to DSM-IV-TR criteria. Spearman correlations analyses were conducted among the different variables. Significant correlations were observed between both tests in all the analyzed variables (omissions, commissions, reaction time, and variability of reaction time), including for those measures of the AULA based on different sensorial modalities, presentation of distractors, and task paradigms. Hence, convergent validity between both tests was confirmed. Moreover, the AULA showed differences by gender and correlation to Perceptual Reasoning and Working Memory indexes of the WISC-IV, supporting the relevance of IQ measures in the understanding of cognitive performance in ADHD. In addition, the AULA (but not Conners’ CPT) was able to differentiate between ADHD children with and without pharmacological treatment for a wide range of measures related to inattention, impulsivity, processing speed, motor activity, and quality of attention focus. Additional measures and advantages of the AULA versus Conners’ CPT are discussed.     

Preterm behavior,maternal adjustment,and competencies in the newborn period: What influence do they have at 12 months postnatal age?

This article examines whether preterm newborns' behavior and their mother's adjustment to the premature birth and infant hospitalization have an influence on subsequent infant development and behavior, maternal adjustment, and mother–infant relationship. The behavioral competencies of 42 well, singleton preterm infants (mean gestational age=31 weeks) were assessed, as were their mothers' adjustment (depression and coping) and competencies (knowledge of child development). At 12 months of postnatal age, child competencies (development and behavior) were assessed, together with maternal adjustment (parenting stress and depression). Mother–infant interaction also was observed. Regression analyses indicated that in the newborn period, maternal positive reappraisal and a planful coping style, more knowledge of child development, and previous experience with baby‐sitting were associated with better infant development (p=.002), maternal adjustment (p=.012), and mother–child relationship (p=.002) at 12 months. Newborn infant muscle‐tone maturity was predictive of better motor quality at 12 months (p=.011), and being a firstborn infant who was more sleepy and drowsy was associated with subsequent higher maternal parenting stress (p=.007). Social and educational support groups combined with an approach that assists mothers to develop problem‐solving coping styles may have a beneficial influence on infant development.     

Mediterranean diet and wellbeing: evidence from a nationwide survey

Objective: Although there is some evidence of the association between specific food groups, such as plant foods, and subjective wellbeing, this is the first study to assess the relationship between adherence to the Mediterranean dietary pattern and subjective wellbeing. Design: Data were collected in 2014–2015, within the Edad con Salud project, a follow-up study of a multistage clustered survey on a representative sample of the population of Spain. The final sample comprised 2397 individuals with ages ranging from 21 to 101 years. Main outcome measures: Experienced wellbeing (positive and negative affect) was measured using the Day Reconstruction Method, and evaluative wellbeing was assessed with the Cantril Self-Anchoring Striving Scale. Results: A higher adherence to the Mediterranean diet showed a small but statistically significant inverse relationship with negative affect (β?=??0.076, p=.001), and direct with evaluative wellbeing (β?=?0.053, p=.015), whereas it was not related to positive affect. Several components of the Mediterranean diet were independently associated with wellbeing. Conclusion: The results suggest that adherence to a dietary pattern such as the Mediterranean diet, and not only the isolated consumption of its components, is associated with a better subjective wellbeing.     

Emotional Intelligence in Selection Contexts: Measurement method,criterion‐related validity,and vulnerability to response distortion

Two studies examined aspects of the validity of self‐report and performance‐based measures of emotional intelligence (EI) relevant to their use in personnel selection. In Study 1, structural equation modeling indicated that a two‐factor model with separate factors for the two types of EI measures fit better than a one‐factor solution. The performance‐based EI factor was more related to cognitive ability (R=.38) than personality (R=.26), whereas the self‐report EI factor was more related to personality (R=.85) than cognitive ability (R=.09). Although the performance‐based EI factor correlated more strongly with job performance (ρ=.24) than did that of the self‐report (ρ=.05), it provided little incremental validity beyond cognitive ability and conscientiousness. In Study 2, participants were asked to complete the measures as if applying for a job, and mean scores were then compared with those of Study 1. Results indicated that self‐report EI measures were more vulnerable to distortion than were the performance‐based measures. Implications for the assessment of EI in personnel selection contexts are discussed.     

Performance-based and parent ratings of attention in children treated for a brain tumor: The significance of radiation therapy and tumor location on outcome

Children are at increased risk for cognitive difficulties following the diagnosis and treatment of a brain tumor. Radiation therapy (RT) and tumor location are commonly-cited predictors of neurocognitive functioning. Disruptions to foundational neurocognitive processes such as attention, working memory, and processing speed underlie declines on measures of general intellectual functioning. While several studies have examined visual sustained attention in pediatric brain tumor patients, auditory sustained attention has yet to be examined. This study employs a longitudinal design to examine performance-based and parent ratings of attention in children undergoing surgical resection of a brain tumor (n = 29) and treated with (n = 11) or without (n = 18) RT at 6.79 months post-surgery (baseline) and then again at 30.56 months post-surgery (follow-up). The measures include an auditory continuous performance test (CPT) and parent ratings of attention and hyperactivity on a behavior rating scale. Ultimately, children treated with and without RT performed similarly on performance-based and parent ratings of attention. However, the performance on the auditory CPT differed according to tumor location, with children with infratentorial tumors committing more inattention and inhibitory control errors compared to children with supratentorial tumors. Parent ratings did not differ according to tumor location, and parent ratings and auditory sustained attention performance are not significantly correlated. The findings are interpreted in the context of neurocognitive and brain development.     

Main and interactive effects of controllability and generalisability attributions upon self-efficacy

ObjectivesThis study examined main effects of controllability and interactive effects of controllability and generalisability attributions upon self-efficacy.DesignA cross-sectional study design was employed with pre-competition self-efficacy assessed at least one week prior to attributions and subsequent self-efficacy.MethodParticipants (N=360; mean age 21.64, SD=6.96 years) completed measures of pre-competition self-efficacy (1 h prior to competition 1), attributions (1 h after competition 1) and subsequent self-efficacy (at least one week following competition 1 and 1 h prior to competition 2). All measures were completed in reference to sport competitions.ResultsDemographic variables and pre-competition self-efficacy were entered as control variables in moderated hierarchical regression analyses. Results demonstrated that individuals who perceived performance as more successful, had higher subsequent self-efficacy when they generalised (ΔR²=.34, p<.01) causes of performance across time (stability: b=.44, p<.01), and/or across situations (globality: b=.47, p<.01), and/or perceived causes to be unique to themselves (universality: b=−.45, p<.01). Individuals who perceived performance as less successful, had higher subsequent self-efficacy when they viewed causes of performance as controllable (ΔR²=.08, b=.23, p<.01); an interaction (ΔR²=.06, p<.05) for controllability and globality (b=.20, p<.01) demonstrated that if causes were perceived to be global, higher levels of controllability were associated with higher levels of subsequent self-efficacy.ConclusionThis study provides evidence, following more successful performances, that attributions to generalisability (stability, globality and universality) affect self-efficacy; following less successful performances, globality (a generalisability dimension) moderates the effect of controllability upon self-efficacy.     

Effects of guided imagery with relaxation training on anxiety and quality of life among patients with inflammatory bowel disease

Background: Inflammatory Bowel Disease (IBD) impacts quality of life (QoL). Psychological factors influence the course of the disease and should be targeted for intervention.

Methods: Our study was a prospective, randomised control trial. Fifty-six outpatients were randomly chosen and allocated to a treatment group or a waiting-list control group. Treatment group patients attended three relaxation-training sessions and received an audio disc for home practice. Evaluations performed pre and post-treatment: state anxiety was assessed with the State-Trait Anxiety Inventory, QoL with the IBD Questionnaire. The Visual Analogue Scale assessed pain, depression, stress and mood. Patients completed a symptom monitoring diary. The control group's symptoms were monitored without study-related treatment.

Results: Thirty-nine subjects completed the study and were included in the data analysis. Following the relaxation-training intervention, the treatment group's (n?=?18) measured results showed a statistically significant improvement as compared to the control group (n?=?21) (time by treatment interaction): anxiety levels decreased (p?<?0.01), QoL and mood improved (p?<?0.05), while levels of pain and stress decreased (p?<?0.01).

Conclusions: Findings indicate IBD patients may benefit from relaxation training in their holistic care. New studies as well as further investigation of the subject are warranted.     

Contralateral Transfer of the Phenomenon of Repeated Bout Rate Enhancement in Unilateral Index Finger Tapping

Abstract

These hypotheses were tested: (1) Freely chosen frequency in unilateral index finger tapping is correlated between the two index fingers, and (2) A 3-min bout of unilateral index finger tapping followed by 10?min rest results in an increase of the freely chosen tapping frequency performed by the contralateral index finger in a second bout. Thirty-two adults participated. Freely chosen tapping frequencies from first bouts were 167.2?±?79.0 and 161.5?±?69.4 taps/min for the dominant and non-dominant hand, respectively (p=.434). These variables correlated (R=.86, p<.001). When bout one and two were performed with the dominant and non-dominant hand, respectively, the frequency increased by 8.1%±17.2% in bout two (p=.011). In opposite order, the frequency increased by 14.1%±17.5% (p<.001), which was not different from the ～8% (p=.157).     

Persistent Problems in Systematic Psychology IV. Structural versus Functional Analysis

The purpose of this investigation was to determine the effect of iris color on critical flicker frequency (CFF). CFF thresholds were obtained on 56 male subjects between the ages of 18 and 25 divided into three groups on the basis of iris color (blue, green, and brown). The results indicate that iris color is a statistically significant factor in the determination of CFF (p < .05), though it was emphasized that the effect may have been due to the correlation between iris color and other ocular pigmentation. The blue-eyed group received the highest mean CFF and the brown-eyed group the lowest mean CFF with the mean CFF threshold of the green-eyed group falling between these values.     

Locus of control and persistence in structured and unstructured preschool classrooms

The effect of locus of control and classroom structure on persistence and attention in preschool children was examined. Teachers' ratings of persistence were obtained for 16 children from a relatively structured classroom and for 18 children from a relatively unstructured classroom. Locus of control was measured by administering the Preschool and Primary Nowicki-Strickland Internal-External Scale (Nowicki & Duke, 1974). As predicted, teachers from the structured classrooms rated externally controlled children as more persistent (r=.55, p<.05), while teachers from the unstructured classroom rated internally controlled children as more persistent (r= -.35, p<.10). Practical implications of this line of research for making classroom placement decisions are discussed.     

Effects of Response Instructions on Faking a Situational Judgment Test

A situational judgment test (SJT) and a Big 5 personality test were administered to 203 participants under instructions to respond honestly and to fake good using a within‐subjects design. Participants indicated both the best and worst response (i.e., Knowledge) and the most likely and least likely response (i.e., Behavioral Tendency) to each situation. Faking effect size for the SJT Behavioral Tendency response format was (d=.34) when participants responded first under honest instructions and (d=.15) when they responded first under faking instructions. Those for the Big 5 dimensions ranged from d=.26 to d=1.0. For the Knowledge response format results were inconsistent. Honest condition Knowledge SJT scores were more highly correlated with cognitive ability (r=.56) than were Behavioral Tendency SJT scores (r=.38). Implications for researchers and practitioners are discussed.
