Telling in-tune from out-of-tune: widespread evidence for implicit absolute intonation

Absolute pitch (AP) is the rare ability to name or produce an isolated musical note without the aid of a reference note. One skill thought to be unique to AP possessors is the ability to provide absolute intonation judgments (e.g., classifying an isolated note as “in-tune” or “out-of-tune”). Recent work has suggested that absolute intonation perception among AP possessors is not crystallized in a critical period of development, but is dynamically maintained by the listening environment, in which the vast majority of Western music is tuned to a specific cultural standard. Given that all listeners of Western music are constantly exposed to this specific cultural tuning standard, our experiments address whether absolute intonation perception extends beyond AP possessors. We demonstrate that non-AP listeners are able to accurately judge the intonation of completely isolated notes. Both musicians and nonmusicians showed evidence for absolute intonation recognition when listening to familiar timbres (piano and violin). When testing unfamiliar timbres (triangle and inverted sine waves), only musicians showed weak evidence of absolute intonation recognition (Experiment 2). Overall, these results highlight a previously unknown similarity between AP and non-AP possessors’ long-term musical note representations, including evidence of sensitivity to frequency.     

Acute Stress,Depression, and Anxiety Symptoms Among English and Spanish Speaking Children with Recent Trauma Exposure

A growing literature suggests the clinical importance of acute stress disorder symptoms in youth following potentially traumatic events. A multisite sample of English and Spanish speaking children and adolescents (N = 479) between the ages of 8–17, along with their caregivers completed interviews and self-report questionnaires between 2 days and 1 month following the event. The results indicate that children with greater total acute stress symptoms reported greater depressive (r = .41, p < .01) and anxiety symptoms (r = .53, p < .01). Examining specific acute stress subscales, reexperiencing was correlated with anxiety (r = .47, p < .01) and arousal was correlated with depression (r = .50, p < .01) and anxiety (r = .55, p < .01). Age was inversely associated with total acute stress symptoms (r = ?.24, p < .01), reexperiencing (r = ?.17, p < .01), avoidance (r = ?.27, p < .01), and arousal (r = ?.19, p < .01) and gender was related to total anxiety symptoms (Spearman’s ρ = .17, p < .01). The current study supports the importance of screening acute stress symptoms and other mental health outcomes following a potentially traumatic event in children and adolescents. Early screening may enable clinicians to identify and acutely intervene to support children’s psychological and physical recovery.     

Similar changes in muscle fiber phenotype with differentiated consequences for rate of force development: Endurance versus resistance training

Resistance training has been shown to positively affect the rate of force development (RFD) whereas there is currently no data on the effect of endurance training on RFD. Subjects completed ten weeks of either resistance training (RT, n = 7) or endurance cycling (END, n = 7). Pre and post measurements included biopsies obtained from m. vastus lateralis to quantify fiber phenotype and fiber area and isokinetic dynamometer tests to quantify maximal torque (Nm) and RFD (Nm/s) at 0–30, 0–50, 0–100 and 0–200 ms during maximal isometric contraction for both knee extensors and flexors. Both groups increased the area percentage of type IIa fibers (p < .01) and decreased the area percentage of type IIx fibers (p = .05), whereas only RT increased fiber size (p < .05). RT significantly increased eccentric, concentric and isometric strength for both knee extensors and flexors, whereas END did not. RT increased 200 ms RFD (p < .01) in knee flexor RFD and a tendency towards an increase at 100 ms (p < .1), whereas tendencies towards decreases were observed for the END group at 30, 50 and 100 ms (p < .1), resulting in RT having a higher RFD than END at post (p < .01). In conclusion, resistance training may be very important for maintaining RFD, whereas endurance training may negatively impact RFD.     

Reading music modifies spatial mapping in pianists

We used a novel musical Stroop task to demonstrate that musical notation is automatically processed in trained pianists. Numbers were superimposed onto musical notes, and participants played five-note sequences by mapping from numbers to fingers instead of from notes to fingers. Pianists' reaction times were significantly affected by the congruence of the note/number pairing. Nonmusicians were unaffected. In a nonmusical analogue of the task, pianists and nonmusicians showed a qualitative difference on performance of a vertical-to-horizontal stimulus-response mapping task. Pianists were faster when stimuli specifying a leftward response were presented in vertically lower locations and stimuli specifying a rightward response were presented in vertically higher locations. Nonmusicians showed the reverse pattern. No group differences were found on a task that required horizontal-to-horizontal mappings. We suggest that, as a result of learning to read and play keyboard music, pianists acquire vertical-to-horizontal visuomotor mappings that generalize outside the musical context.     

Cross-lateralisation in children with attention-deficit/hyperactivity disorder and motor skill performance

Cross-lateralisation and increased motor difficulties have been reported in children with attention-deficit/hyperactivity disorder (ADHD). Nevertheless, the question of how crossed (i.e. mixed preference) or uncrossed (i.e. same side preference) lateralisation impacts motor performance in children with ADHD has yet to be examined. In this study, previously validated observational measures of hand and foot preference were used to identify right-handed children with ADHD who display cross- (n = 29) and uncross-lateralisation (n = 31). An uncross-lateralised typically developing (TD) group (n = 32) was also identified, and included as a control. Motor performance was assessed with seven valid and reliable fine and gross motor tasks performed with both preferred and non-preferred limbs. Group, task and sex-related effects were examined. Findings revealed that male (but not female) cross-lateralised children with ADHD performed significantly worse, respectively, in two of the fine motor tasks (spiral tracing [p < .01], and dot filling [p < .05]). Results suggest that cross-lateralised hand and foot preference may affect complex motor skills in male children with ADHD. Furthermore, characteristics of ADHD may manifest differently in male and female children. Findings highlight the importance of considering both hand and foot preference when targeting motor interventions for children with ADHD.     

Hemispheric asymmetries in the perception of musical intervals as a function of musical experience and family handedness background

This study examines the effect of musical experience and family handedness background on the categorization of musical intervals (two-note chords). Right-handed subjects, who were divided into four groups on the basis of musical training and presence (or absence) of left-handed family members, categorized musical intervals which were monaurally presented to left or right ear. The results, based on consistency and discreteness of categorization, showed: (1) Musicians' performance is superior to nonmusicians'; (2) musicians and nonmusicians differ significantly on their ear of preference; (3) family handedness background significantly affects ear of preference among musicians but not among nonmusicians.     

Predicting changes in planning behaviour and physical activity among adults

Though the effect of action planning upon behavioural enactment is becoming well-established, adherence to planning interventions are modest. Motivations specific to action planning may predict planning behaviour. The primary purpose of the present study was to determine if theory of planned behaviour constructs operationalized for planning could predict change in planning behaviour. The secondary purpose was to determine if planning behaviour predicted changes in physical activity. Participants (n = 337, M_age = 31 ± 5) were adults with intentions to be more active who completed measures of affective and instrumental attitudes towards planning, subjective norms towards planning, perceived behavioural control over planning, intentions to plan, self-reported planning behaviour, intentions to be active and self-reported physical activity at baseline (T1) and after four weeks (T2). Affective attitudes towards planning (β = 0.10, p < .05), instrumental attitudes towards planning (β = 0.22; p < .01) subjective norms over planning (β = 0.12, p < .01) and perceived behavioural control over planning (β = 0.53, p < .01) predicted intentions to plan (adj. R² = 0.66). Intentions to plan (β = 0.16, p < .05) and intentions to be active (β = −0.25, p < .05) predicted change in planning behaviour (R²_change = 0.03). Planning behaviour (β = 0.27, p < .05) predicted change in physical activity (R²_change = 0.07). Planning behaviour appears to have its own motivations distinct from those of physical activity. Future interventions should target planning behaviour along with its motivations and control beliefs to increase rates of planning. The theoretical underpinnings of the TPB are of value for understanding both planning behaviour and physical activity.     

Theory of Planned Behavior: Implications for an email-based physical activity intervention

ObjectivesA 3-week study was conducted to determine the effect of persuasive messages sent via email on psychological constructs associated with Theory of Planned Behavior (TPB) and exercise behavior in sedentary college students (N=170).MethodsParticipants (105 M; 65 F; 94% Caucasian; 20.2±.9 years) completed the Godin Leisure Time Exercise Questionnaire (GLTEQ) and self-report measures of the TPB. Participants received persuasive messages every other day for 2 weeks. One randomly assigned group received positively framed messages (PFM; n=57); the other received negatively framed messages (NFM, n=57); and the control group (CG; n=56) received none. Participants completed the GLTEQ and TPB questionnaires following the 2-week treatment phase and again 1 week later.ResultsANCOVA results revealed that PFM reported higher exercise behavior levels than both NFM and CG at follow-up (p<.05) and retention (p<.05). For exercise intention, PFM and NFM reported significantly higher levels than CG at follow-up (p<.05), while PFM reported higher levels than NFM and CG at retention (p<.05). Also, pairwise comparisons revealed higher intention levels for NFM compared to CG at retention (p<.05). PFM reported higher levels of affective attitude compared to CG at follow-up (p<.05) and retention (p<.05), while NFM reported higher levels than CG at follow-up (p<.05). For instrumental attitude, all three groups were statistically different (p<.05) at retention (PFM>NFM, NFM>CG, PFM>CG).ConclusionsOnly positively framed persuasive messages sent via email improved exercise behavior. Both types of messages affected attitude, and intention in sedentary young adults. This research provides useful information for creating interventions to enhance exercise adherence.     

Match performance and physical capacity of players in the top three competitive standards of English professional soccer

The aim of this study was to compare the match performance and physical capacity of players in the top three competitive standards of English soccer. Match performance data were collected from players in the FA Premier League (n = 190), Championship (n = 155) and League 1 (n = 366) using a multiple-camera system. In addition, a selection of players from the Premier League (n = 56), Championship (n = 61) and League 1 (n = 32) performed the Yo-Yo intermittent endurance test level 2 (Yo-Yo IE2) to determine physical capacity. Players in League 1 and the Championship performed more (p < .01) high-intensity running than those in the Premier League (Effect Size [ES]: 0.4–1.0). Technical indicators such as pass completion, frequency of forward and total passes, balls received and average touches per possession were 4–39% higher (p < .01) in the Premier League compared to lower standards (ES: 0.3–0.6). Players also covered more (p < .05) high-intensity running when moving down (n = 20) from the Premier League to the Championship (ES: 0.4) but not when players moved up (n = 18) standards (ES: 0.2). Similar Yo-Yo IE2 test performances were observed in Premier League, Championship and League 1 players (ES: 0.2–0.3). Large magnitude relationships (p < .05) were observed between Yo-Yo IE2 test performances and the total and high-intensity running distance covered in both Championship (r = .56 and .64) and Premier League matches (r = .61 and .54). The data demonstrate that high-intensity running distance was greater in players at lower compared to higher competitive standards despite a similar physical capacity in a subsample of players in each standard. These findings could be associated with technical characteristics inherent to lower standards that require players to tax their physical capacity to a greater extent but additional research is still required to confirm these findings.     

Experiential avoidance in body dysmorphic disorder

Experiential avoidance (i.e., the attempt to avoid certain internal experiences including bodily sensations, thoughts, emotions, memories, and urges) has been studied in various psychological disorders. However, research examining experiential avoidance in individuals with body dysmorphic disorder (BDD) is limited and inconsistent. The present study compared experiential avoidance in individuals with primary BDD (n = 23) to healthy controls (n = 22). Standardized measures were used to assess baseline clinical characteristics as well as experiential avoidance. Compared to healthy controls, individuals with BDD presented with significantly greater experiential avoidance (p < .001, d = −2.51). In BDD, experiential avoidance was positively correlated with depressive symptoms (p < .01) and avoidant coping strategies (p < .01). Clinician sensitivity to experiential avoidance may serve to improve the course of treatment for BDD.     

Psychosocial correlates of depressive rumination

The study examined the relationship between brooding, the maladaptive sub-component of depressive rumination, an important cognitive mechanism implicated in the aetiology of depression, and a range of depressogenic psychosocial factors, including insecure attachment styles and maladaptive interpersonal behaviours. It was hypothesised that brooding (but not the more adaptive reflection component) is associated with an attachment pattern characterised by fear of rejection, and an interpersonal style characterised by submissiveness. Currently depressed (n = 29), previously depressed (n = 42) and never-depressed (n = 32) adults completed self-report measures assessing depressive symptoms, rumination (brooding and reflection), attachment orientation and maladaptive interpersonal behaviours. The study hypotheses were partially supported: After controlling for gender and depressive symptoms, brooding was significantly associated with one indicator of underlying rejection concerns (rejection sensitivity, p = .05), but was not associated with another indicator of underlying rejection concerns (anxious attachment style) or with avoidant attachment style. After controlling for depressive symptoms, brooding was uniquely associated with the submissive interpersonal style (p < .01). Brooding was not correlated with needy or cold interpersonal styles after controlling for depressive symptoms.     

Understanding action control of resistance training among adults

BackgroundRegular muscle and bone strengthening activities through resistance training (RT) have been associated with numerous health benefits, particularly as adults age, yet participation is low. Effective promotion is likely founded on an understanding of theory-based correlates, yet almost all RT research has focused on college-aged convenience samples and employed social cognition models, which do not consider the intention-behavior gap. The purpose of this study was to explore RT from the perspective of the multi-process action control (M-PAC) framework in a large Canadian adult sample.MethodCanadian adults (N = 1338) completed M-PAC measures of reflective (instrumental attitude, affective attitude, perceived capability and opportunity), regulatory (planning and self-monitoring), and reflexive (habit, identity) processes as well as intention to engage in RT at baseline and RT behavior two-weeks later.ResultsThree intention-behavior profiles emerged: a) non-intenders who were not active (41.4%), b) unsuccessful intenders who failed to enact their positive intentions (32.9%), and c) successful intenders who engaged in RT (23.5%). A discriminant function analysis (p < .01) showed that instrumental and affective attitude, perceived opportunity and planning/self-monitoring distinguished between all three intention-behavior profiles, while perceived capability predicted the intention-RT profiles of females but not males (p < .01). By comparison, identity was particularly important to younger/middle-aged adults than older females (p < .01), while habit was associated with the intention-RT profiles of older adults but not younger/middle-aged adults (p < .01).ConclusionsThe findings support the importance of considering both intention formation and translation in RT. Behavior change techniques aimed at reflective, regulatory, and reflexive processes appear necessary. Additional considerations of targeting specific constructs by age and sex may maximize the potential effectiveness of RT interventions.     

The Simple Copy Task: Detecting Higher Order Visual Processing Deficits in Schizophrenia,Dementia, and Movement Disorder Groups

The Simple Copy Task (SCT) is a figure copying test with inherent appeal due to its short administration time, graded task difficulty, varied stimuli, and potential to eliminate floor effects. Despite this, there is a lack of data regarding its construct validity and diagnostic utility. The present study compared SCT performance of schizophrenia (n = 29), dementia (n = 64), and movement disorder (n = 12) groups with that of unmatched healthy control participants (n = 49). Movement disorder patients committed a high degree of misplacement errors, whereas dementia patients tended to omit items, add extraneous detail, and perseverate. The schizophrenia group was most similar to the dementia group in their performance on the SCT, committing primarily omission and perseveration errors. The SCT was most closely related to the Rey Complex Figure Task (r = 0.68, p < .01) and the Block Design Task (r = 0.62, p < .01). Age (r = ?0.14, p < .01) and education (r = 0.35, p < .01) effects were present; however, there was no impact of gender and handedness. Taken together, these findings provide support for the utility of the task and directions for clinical interpretation.     

Teachers' perceptions of children's sport learning capacity predicts their fundamental movement skill proficiency

The intrapersonal mechanism that drives and explains individual differences in motor development is still a relatively underexplored area of research. In this study, we set out to determine whether in teachers' perceptions, higher sport-learning capacity (SLC) is associated with the level of fundamental movement skills, and the changes therein over 24 weeks in 7-year-olds. We assessed 170 children from eight primary schools in the Netherlands twice (T1, T2) in 24 weeks, using a tool to assess their FMS in applied settings (Platvoet, Elferink-Gemser, & Visscher, 2018). The schools' eight PE teachers used a digital questionnaire to score their perceptions of children's SLC (Platvoet, Elferink-Gemser, Baker, & Visscher, 2015). Based on their SLC, each child was then placed in the low (n = 33), average (n = 107), or high SLC-group (n = 30). We used a MANOVA to examine group differences, with the four subtests as dependent variables. The results revealed that regardless of SLC-group, children improved their FMS over 24 weeks (F(4,163) = 10.22, p < .05, Wilks Lamba = 0.800). An interaction effect was found for FMS assessment and SLC-group (F(8,326) = 2.23, p < 0,05, Wilks Lamba = 0.899). The children in the average and high groups improved more on the moving sideways subtest than those in the low group (p < .05). The MANOVA showed a main effect for SLC-group (F(4,163) = 4.69, p < .05, Wilks Lamba = 0.804). The average and high groups outperformed the low group on the measurements for walking backwards and moving sideways (p < .05). The high group also outperformed the low group on jumping sideways at both measurements, while the average group only achieved this at T1. The high group scored better on jumping sideways than the average group at T1 (p < .05). No differences in proficiency were found between the three groups on the hand-eye coordination assessment (p > .05). In sum, we found an association between children's SLC and level of FMS and changes therein; this was especially pronounced in children with a lower SLC, who had a lower proficiency and improved less on the subtest moving sideways.     

Positive Traits Linked to Less Pain through Lower Pain Catastrophizing

The present study examined the association between positive traits, pain catastrophizing, and pain perceptions. We hypothesized that pain catastrophizing would mediate the relationship between positive traits and pain. First, participants (n = 114) completed the Trait Hope Scale, the Life Orientation Test-Revised, and the Pain Catastrophizing Scale. Participants then completed the experimental pain stimulus, a cold pressor task, by submerging their hand in a circulating water bath (0 °C) for as long as tolerable. Immediately following the task, participants completed the Short-Form McGill Pain Questionnaire (MPQ-SF). Pearson correlation found associations between hope and pain catastrophizing (r = −.41, p < .01) and MPQ-SF scores (r = −.20, p < .05). Optimism was significantly associated with pain catastrophizing (r = −.44, p < .01) and MPQ-SF scores (r = −.19, p < .05). Bootstrapping, a non-parametric resampling procedure, tested for mediation and supported our hypothesis that pain catastrophizing mediated the relationship between positive traits and MPQ-SF pain report. To our knowledge, this investigation is the first to establish that the protective link between positive traits and experimental pain operates through lower pain catastrophizing.     

Prevalence,correlates, and psychosocial outcomes of sport participation in young adult cancer survivors

Young adult cancer survivors (YACS) face unique challenges from their disease and treatments that may influence their sport participation choices as well as their psychosocial response.ObjectivesTo examine the prevalence, correlates, and psychosocial outcomes of sport participation in YACS.DesignA provincial, population-based mailed survey of 588 YACS in Alberta, Canada, was completed in May 2008 and included measures of sport participation, psychosocial health (depression, self-esteem, and stress), quality of life (QoL), and medical and demographic variables.ResultsOne third (32.5%) of YACS reported participating in a sport in the past month with the most common being golf (40.8%) and ice hockey (8.3%). YACS participating in sport reported an average frequency of 1.7 (SD = 1.0) days/week and an average duration of 119 min/session (SD = 68) for a total of 189 (SD = 164) min/week. Independent t-tests showed that YACS who participated in sport reported better psychosocial health and QoL including physical QoL (p < 0.001), mental QoL (p < 0.001), self-esteem (p < 0.001), depression (p < 0.001), and stress (p < 0.001). In multivariate regression analysis, 8.5% (p < 0.001) of the variance in sport participation was explained by being male (β = 0.17, p < 0.001), Caucasian (β = 0.15, p = 0.001), in better general health (β = 0.15, p < 0.001), and having a normal body mass index (β = ?0.10, p = 0.024).Discussion/conclusionsSport participation is associated with better psychosocial health and QoL in YACS but only a third participated in the past month. Randomized controlled trials examining sport as an intervention strategy to increase physical activity and improve health outcomes in YACS are warranted.     

Clarifying relationships among work and family social support, stressors, and work-family conflict

Although work and family social support predict role stressors and work-family conflict, there has been much ambiguity regarding the conceptual relationships among these constructs. Using path analysis on meta-analytically derived validity coefficients (528 effect sizes from 156 samples), we compare three models to address these concerns and clarify relationships. Results revealed that social support, controlling for role involvement, is best viewed as an antecedent of role stressors and subsequent work-family conflict. Controlling for work and family involvement, work and family social support were most related to same domain role conflict (β = −.46, p < .05; β = −.43, p < .05) and role ambiguity (β = −.28, p < .05; β = −.33, p < .05). Subsequently, work role conflict and time demands were most related to work-to-family conflict (β = .39, p < .05; β = .21, p < .05), while family role conflict and role ambiguity were most related to family-to-work conflict (β = .22, p < .05; β = .24, p < .05). Implications for research and practice, along with suggestions for theoretical advances, are discussed.     

Gender differences in rumination: A meta-analysis

Starting in adolescence and continuing through adulthood, women are twice as likely as men to experience depression. According to the response styles theory (RST), gender differences in depression result, in part, from women’s tendency to ruminate more than men. A meta-analysis was performed to evaluate gender differences in rumination in adults (k = 59; N = 14,321); additionally, an analysis of subtypes of rumination – brooding and reflection – was conducted (k = 23). Fixed effects analyses indicated that women scored higher than men in rumination (d = .24, p < .01, SEd = .02), brooding (d = .19, p < .01, SEd = .03) and reflection (d = .17, p < .01, SEd = .03); there was no evidence of heterogeneity or publication bias across studies for these effect sizes. Although statistically significant, the effect sizes for gender differences in rumination were small in magnitude. Results are discussed with respect to the RST and gender differences in depression.     

The effects of lemon taste on attention,perceived exertion,and affect during a stepping task

ObjectivesTo better understand the effects of taste cues on delaying the attention shift from an external focus (dissociative) towards an internal focus (associative) as exercise intensity increases.DesignA between subjects' experimental design with random assignment to three groups: taste (lemon-flavored mouth guards), placebo (unflavored mouth guards), or control group (no mouth guards) was used. Participants reported perceived exertion, affect (i.e., pleasantness and arousal), and attention allocation before, during, and after performing a weighted stepping task.ResultsPerforming the task resulted in a gradual increase of perceived exertion, F (1.87, 74.89) = 63.05, p < .05, η_p² = .61, along with a shift from dissociative to associative attention, F (2.17, 86.68) = 35.57, p < .05, η_p² = .47 across all conditions. Additionally, participants reported feeling less pleasant and more aroused after task completion in all conditions. The lemon-flavored mouth guard failed to affect attention, F (4.33, 86.68) = 1.41, p = .23, η_p² = .07, perceived exertion, F (3.74, 74.86) = .38, p = .81, η_p² = .02, pleasantness, F (2, 40) = .126, p = .88, η_p² = .01, and arousal, F (2, 40) = 2.40, p = .10, η_p² = .10, differently than the other two conditions.ConclusionsThe study was one of the first to examine the effects of taste during an exertive task. Despite the non-significant effects of using a lemon-taste mouth guard on various cognitive variables (perception of exertion, attention allocation, pleasantness, and arousal), more scientific effort is needed to explore the effects of other tastes (e.g., sweet, bitter) and delivery methods (e.g., sprays, drops).     

Sleep disturbance and emotion dysregulation as transdiagnostic processes in a comorbid sample

Sleep disturbance and emotion dysregulation have been identified as etiologic and maintaining factors for a range of psychopathology and separate literatures support their relationships to anxiety, depression, PTSD, and alcohol dependence (AD) symptom severity. Previous studies have examined these relationships in isolation, failing to account for the high rates of comorbidity among disorders. It is not yet known whether these processes uniquely predict symptom severity in each of these domains. Participants were 220 patients in residential substance abuse treatment, who had experienced a potentially traumatic event and exceeded screening cutoffs for probable PTSD and problematic alcohol use. Controlling for emotion dysregulation and the interrelationships among the outcome variables, insomnia was uniquely associated with anxiety (B = .27, p < .001), depression (B = .25, p < .001), PTSD (B = .22, p < .001), and AD (B = .17, p = .01) symptom severity. Similarly, controlling for insomnia, emotion dysregulation was uniquely associated with anxiety (B = .40, p < .001), depression (B = .47, p < .001), PTSD (B = .38, p < .001), and AD (B = .26, p < .001) symptom severity. Insomnia and emotion dysregulation appear to be transdiagnostic processes uniquely associated with symptom severity across a number of different domains and might be important treatment targets for individuals with PTSD and AD.
