Harmonic,melodic, and frequency height influences in the perception of multivoiced music

Two experiments addressed the influences of harmonic relations, melody location, and relative frequency height on the perceptual organization of multivoiced music. In Experiment 1, listeners detected pitch changes in multivoiced piano music. Harmonically related pitch changes and those in the middle-frequency range were least noticeable. All pitch changes were noticeable in the high-frequency voice containing the melody (the most important voice), suggesting that melody can dominate harmonic relations. However, the presence of upper partials in the piano timbre used may have accounted for the harmonic effects. Experiment 2 employed pure sine tones, and replicated the effects of Experiment 1. In addition, the influence of the high-frequency melody on the noticeability of harmonically related pitches was lessened by the presence of a second melody. These findings suggest that harmonic, melodic, and relative frequency height relationships among voices interact in the perceptual organization of multivoiced music.     

Constraints on strategy construction in a speeded discrimination task

In three experiments, subjects reported the identity of a word (above or below) that appeared above or below a fixation point. On some trials, a cue presented 100, 200, 400, 600, 800, or 1,000 msec before the word indicated the relation between position and identity (i.e., whether the dimensions were compatible, e.g., above/above and below/below, or conflicted, e.g., above/below and below/above). On the other trials, the cue was withheld (Experiment 2) or it bore no information about the relation between dimensions (Experiment 1 and 3). In each experiment, the cue reduced reaction time below the level of no-cue or neutral-cue controls, indicating strategic use of the relation between dimensions. Experiments 1 and 2 manipulated the number of potential cues that could occur in a block. A stronger cuing effect was found when one cue could occur (Experiment 2) than when two cues could occur (Experiment 1). Experiment 3 manipulated practice; it revealed that with practice the cuing effect reached asymptote at shorter delays. The asymptote itself did not change. Experiment 4 showed that cue-delay effects were independent of warning interval (warning interval and cue delay confounded in Experiment 1, 2, and 3). The experiments demonstrate construction and utilization of strategies; they show that construction is sensitive to constraints imposed by the subject's goals and abilities and by the structure of the task environment.     

Children in family therapy

The distinctive skills of child psychotherapy can be utilized in the development of a form of conjoint family therapy especially applicable to the field of child psychiatry. It is suggested that the engagement of children in the process particularly enhances the specific characteristics and potentialities of this form of treatment.     

Rural High School Students' Perceptions of the Basic Values and Educational Philosophies of Significant Secondary School Role Models

This research investigated rural high school students' perceptions of two major secondary school role models' (teachers and popular peers) solutions to five ontological and axiological problem spheres. The Values Orientation Questionnaire (VOQ), an operationalization of F. Kluckhohn's theory of intra-cultural value variation, was completed each of three times during three months: initially for the self and then according to the way the respondent felt the models would respond. Achievement, an index of successful school encounters, was entered as the between-persons factor in a multivariate-model repeated-measures ANCOVA. Generally, the students believe that teachers and popular peers endorse that set of values that forms the foundation of progressive counseling and educational philosophies and practices and is, to a large extent, our middle-class system. Students perceive teachers as overendorsing (relative to self) those ontological choices that form the valuational basis of authoritarian counseling and educational theories. These seemingly contradictory teachers' attributions are discussed in terms of the teachers' roles and of institutional demands that often force teachers to model behaviors that neither they nor society deems desirable.     

Virtual Reality One-Session Treatment of Child-Specific Phobia of Dogs: A Controlled,Multiple Baseline Case Series

Specific phobia (SP) typically onsets in childhood and frequently predicts other mental health disorders later in life. Fortunately, childhood SP can be effectively treated with cognitive behavior therapy (CBT), including the exposure-based one-session treatment (OST) approach. Despite empirical support for CBT and OST, clinicians, for various reasons, frequently fail to implement exposure-based therapy in routine clinical practice, including perceived difficulties in implementing exposure. Virtual reality (VR) exposure therapy may overcome some of these challenges and provides an alternative modality of therapy. This preliminary study examined the efficacy of VR OST for 8 children with a SP of dogs (aged 8–12 years) (M = age 10.25; SD = 2.11) using a multiple-baseline controlled case series. Following a stable baseline period of either 2, 3, or 4 weeks, it was expected that specific phobia severity would significantly decline after VR OST and remain improved over the 3-week maintenance phase. Assessments were conducted posttreatment and at 1-month follow up (study end-point). It was found that phobia symptoms remained relatively stable across the baselines, with significant reductions from pretreatment to posttreatment and to follow-up on clinician severity ratings (pre- to post- g = 1.12; pre- to follow-up g = 2.40), target symptom ratings (g = 1.14; 1.29), and behavioral avoidance (g = -1.27; -1.96). The treatment was also associated with clinically significant outcomes, whereby at one-month follow up, 75% of children were considered “recovered” and 88% completed the BAT (interacted with their feared stimuli). This study provides support for the effectiveness of VR OST.     

Trauma exposure and post-traumatic stress symptoms among Syrian refugee youth in Jordan: Social support and gender as moderators

This study assessed relations between exposure to trauma and post-traumatic stress (PTS) symptoms, and whether perceived social support from family and friends and gender moderated these associations. Syrian refugee youth (N = 418, 55.0% female) attending public schools in Jordan participated. Boys reported more age-adjusted PTS symptoms than girls. Analyses revealed that family support and gender moderated the association of trauma on PTS symptoms. For males, the benefits of family support were most evident under conditions of high traumatic stress exposure, while for females, benefits of family support were evident when no loss or injury to family members had been reported. Support from friends was not helpful for either gender. School- or family-based interventions designed to treat PTS symptoms need to consider the different needs of boys and girls, particularly within the Syrian Muslim cultural context.     

Dynamic relationships between phonological memory and reading: A five year longitudinal study from age 4 to 9

We reconcile competing theories of the role of phonological memory in reading development, by uncovering their dynamic relationship during the first 5 years of school. Phonological memory, reading and phoneme awareness were assessed in 780 phonics‐educated children at age 4, 5, 6 and 9. Confirmatory factor analyses demonstrated that phonological memory loaded onto two factors: verbal short‐term memory (verbal STM; phonological tasks that loaded primarily on serial order memory) and nonword repetition. Using longitudinal structural equation models, we found that verbal STM directly predicted early word‐level reading from age 4 to 6, reflecting the importance of serial‐order memory for letter‐by‐letter decoding. In contrast, reading had no reciprocal influence on the development of verbal STM. The relationship between nonword repetition and reading was bidirectional across the 5 years of study: nonword repetition and reading predicted each other both directly and indirectly (via phoneme awareness). Indirect effects from nonword repetition (and verbal STM) to reading support the view that phonological memory stimulates phonemically detailed representations through repeated encoding of complex verbal stimuli. Similarly, the indirect influence of reading on nonword repetition suggests that improved reading ability promotes the phoneme‐level specificity of phonological representations. Finally, the direct influence from reading to nonword repetition suggests that better readers use orthographic cues to help them remember and repeat new words accurately.
