Influence of tonal and temporal expectations on chord processing and on completion judgments of chord sequences

Pitch and time are two principal form-bearing dimensions in Western tonal music. Research on melody perception has shown that listeners develop expectations about "What" note is coming next and "When" in time it will occur. Our study used sequences of chords (i.e., simultaneously sounding notes) to investigate the influence of these expectations on chord processing (Experiments 1 and 4) and subjective judgments of completion (Experiments 2 and 3). Both tasks showed an influence of tonal relations and temporal regularities: expected events occurring at the expected moment were processed faster and led to higher completion judgments. However, pitch and time dimensions interacted only for completion judgments. The present outcome suggests that for chord perception the influence of pitch and time might depend on the required processing: with a more global judgment favoring interactive influences in contrast to a task focusing on local chord processing.     

Attentional cues in real scenes, saccadic targeting, and Bayesian priors

Performance finding a target improves when artificial cues direct covert attention to the target's probable location or locations, but how do predictive cues help observers search for objects in real scenes? Controlling for target detectability and retinal eccentricity, we recorded observers' first saccades during search for objects that appeared in expected and unexpected locations within real scenes. As has been found with synthetic images and cues, accuracy of first saccades was significantly higher when the target appeared at an expected location rather than an unexpected location. Observers' saccades with target-absent images make it possible to distinguish two mechanisms that might mediate this effect: limited attentional resources versus differential weighting of information (Bayesian priors). Endpoints of first saccades in target-absent images were significantly closer to the expected than the unexpected locations, a result consistent with the differential-weighting model and inconsistent with limited resources being the sole mechanism underlying the effect.     

Depression, Marital Satisfaction and Communication in Couples: Investigating Gender Differences

The correlation between depression and dysfunctional marital interaction is well documented, but only a few studies have examined gender-related differences in marital interaction patterns of couples with a depressed partner. In this paper we examined differences in observed marital communication in a sample of 62 Swiss couples presenting for treatment of depression. There were 16 maritally distressed couples with a depressed wife, 21 maritally nondistressed couples with a depressed wife, 18 maritally distressed couples with a depressed husband, and 7 maritally nondistressed couples with a depressed husband. Marital interaction behavior was found to depend on gender, depression, marital distress, as well as gender of the depressed partner. Our results suggest the need for a gender-sensitive model of the link between marital interaction and depression.     

Cognitive-behavioral treatment of childhood obsessive-compulsive disorder in community-based clinical practice: clinical significance and benchmarking against efficacy

Objective

To evaluate the feasibility and outcomes of evidence-based (EB) manualized, cognitive-behavioral treatment (CBT) for childhood obsessive-compulsive disorder (OCD), when delivered in an outpatient community-based specialist clinic.

Method

This study, conducted in an outpatient private clinic in South-East Queensland Australia, involved thirty-three children and adolescents with OCD. Children were assessed at pre- and post-treatment, by means of diagnostic interviews, symptom severity interviews, and self-report. Treatment involved 12 sessions CBT delivered either individually or in small groups and included parental involvement.

Results

Manualized CBT could be transported to the community setting effectively, with 63% of the current sample responding positively, based on post-treatment diagnosis. Significant change was evident across a wide-range of outcomes; including, diagnostic severity, symptom severity, child reported depression and anxiety, and both child and parent reported OCD functional impairment.

Conclusions

This study provides evidence for the transportability of manualized CBT in clinical community practice for pediatric OCD. The next important step is larger community based dissemination and effectiveness studies to advance both research and clinical practice outcomes.     

Telling perfectionists about their perfectionism: Effects of providing feedback on emotional reactivity and psychological symptoms

A randomized, controlled clinical trial was conducted to determine the efficacy of receiving feedback in a sample of maladaptive perfectionists. A total of 60 young adults were randomly assigned to a feedback intervention or control group. Hierarchical Linear Modeling was utilized to analyze the effects of perfectionism over time, as well as the effects of treatment condition on the relationship between perfectionism and outcomes. Measures of interest included emotional reactivity, self-esteem, and psychological distress. Findings revealed that providing feedback to maladaptive perfectionists reduced self-reported global symptomatic distress as well as emotional reactivity. The results are discussed in light of treatment implications, especially with regard to the manner in which perfectionists respond to therapeutic interventions. Overall, study findings suggest that a brief, low-cost feedback intervention is effective at decreasing psychological distress in maladaptive perfectionists and may serve as a beneficial precursor to individual therapy or counseling.     

Spirituality,Anger, and Stress in Early Adolescents

The purpose of this study was to explore the relationship of spiritual beliefs and involvement with anger and stress in early adolescents. Early adolescents (n = 53) completed the Spiritual Involvement and Beliefs Scale (Hatch et al. 1998), the State-Trait Anger Expression Inventory (Spielberger 1999), and the Perceived Stress Scale (Cohen and Williamson 1988). Contrary to expectations, spirituality was significantly and positively related to anger and stress. Implications and possible explanations for the unanticipated findings in this study are discussed.     

Leader power and leader self-serving behavior: The role of effective leadership beliefs and performance information

In this research we investigated the role played by leader power in determining leader self-serving behavior. Based on an integration of insights from research on the determinants of leader behavior and the power-approach theory, we hypothesized that with higher leader power leader self-serving behavior is determined more by internal states like effective leadership beliefs and less by external cues like performance information. We found support for this prediction across two experiments and one organizational survey assessing leader behavior along a self-serving–group-serving continuum. Overall, these results suggest that whether leaders benefit the collective or act self-servingly is not a function of their power per se but rather that leader power determines the extent to which internal belief states or external cues influence leader self- versus group-serving behavior.     

When Sibling Becomes Competitor: A Qualitative Investigation of Same-Sex Sibling Competition in Elite Sport

Abstract

The effects of performance strategies, goal setting, and self-evaluative recording on the acquisition of a novel motoric skill were studied with 90 high school girls. It was hypothesized that greater acquisition would occur when (a) an analytic strategy was used instead of imaginal strategy, (b) practice goals were shifted dynamically during learning instead of remaining unchanging or fixed, and (c) self-evaluative recording of strategic performance processes was present rather than absent. Support for all three hypotheses was found. In addition to improving motoric skill acquisition, these same self-regulatory processes significantly enhanced three sources of learners' motivation: self-efficacy beliefs, self-satisfaction, and intrinsic interest. Additional analyses revealed that self-evaluative recording enhanced strategy attributions during learning which were predictive of improved self-efficacy, self-satisfaction, and intrinsic interest during posttesting. Self-efficacy was highly predictive of subsequent dart-skill performance. The results were discussed in terms of a strategic cycle view of self-regulation of motoric learning.     

Psychology,Religion, and Spirituality

This study focused on the relation between the manner in which pray-ers perceive God (God concept) and their tendencies to choose various prayer types. A sample of 114 Jewish Israeli religious men responded to multidimensional measures of God concept (Benevolent, Evaluation, Omniness, Guiding, and Deisticness) and of prayer type (Adoration, Confession, Thanksgiving, Supplication, Reception). Canonical correlation analysis uncovered a significant canonical model. Two canonical functions, explaining a total of 36.5% of the variance, were selected for interpretation. Function 1 indicated a perception of God as a benevolent and guiding God together with supplicative prayer. Function 2 indicated a perception of God as a meaningful and close God with active thanksgiving prayer. These results provide support for the notion that the manner in which an individual perceives God and the manner in which that individual chooses to pray to God are indeed related.
