Absolute and relative pitch: Global versus local processing of chords

Absolute pitch (AP) is the ability to identify or produce notes without any reference note. An ongoing debate exists regarding the benefits or disadvantages of AP in processing music. One of the main issues in this context is whether the categorical perception of pitch in AP possessors may interfere in processing tasks requiring relative pitch (RP). Previous studies, focusing mainly on melodic and interval perception, have obtained inconsistent results. The aim of the present study was to examine the effect of AP and RP separately, using isolated chords. Seventy-three musicians were categorized into four groups of high and low AP and RP, and were tested on two tasks: identifying chord types (Task 1), and identifying a single note within a chord (Task 2). A main effect of RP on Task 1 and an interaction between AP and RP in reaction times were found. On Task 2 main effects of AP and RP, and an interaction were found, with highest performance in participants with both high AP and RP. Results suggest that AP and RP should be regarded as two different abilities, and that AP may slow down reaction times for tasks requiring global processing.     

Facilitation of attitude formation through communication: how perceived source expertise enhances the ability to achieve cognitive closure about complex environmental topics

Attitudes on which people have achieved cognitive closure are better predictors of future attitudes and behavior than open attitudes. In two experiments, we found that factors in communication (source identity, source consensus) can enhance people's ability to achieve cognitive closure on complex environmental topics through an increase in perceived source expertise. Results showed that participants perceived higher levels of source expertise and felt better able to achieve cognitive closure on the environmental technology of carbon dioxide capture and storage (CCS) when the information source had an expert identity compared to a non‐expert identity. The communication of consensus by the information source increased the level of expertise ascribed to the non‐expert source, resulting in an enhanced ability to achieve closure.     

Improved Parental Emotional Functioning After Circle of Security 20-Week Parent–Child Relationship Intervention

This study examined the effectiveness of the attachment-based Circle of Security 20-week intervention (COS) in improving parent emotional functioning in 83 families referred to a community clinical service with concerns about their young children’s behavior. Parenting stress and parent psychological symptoms were assessed pre and post intervention and mixed design repeated measures ANOVAs were used to assess change. Severity of presenting problems was considered as a moderator. Results showed clinically significant improvements in both aspects of parent emotional functioning, with changes accounted for by for those with more severe problems at the outset. Improvements for parents were associated with improved child behavior and more positive parent representations of the child and of parenting capacity. Findings suggest the intensive COS intervention is effective in reducing parenting stress and psychological symptoms in parents of children from aged 1–7 years. Questions remain about the mechanisms of change and the direction of effects.
