Understanding Envelopes in Synthesis (Intermediate)

Author(s):  
Misty Jones Simpson

Understanding how synthesizers generate sounds is an important aspect of learning how to produce electronic music. In this game-based activity designed for undergraduate students, I outline how to use analogies to help students understand how ADSR (attack, decay, sustain, release) envelopes work as they relate to synthesis. Starting with a piece of paper and a letter envelope, learners start by understanding the concept visually with physical objects. Following, learners are provided opportunities to apply these analogies when working with envelope modules on synthesizers. By applying this knowledge, students can use envelope parameters more effectively to achieve the sound they wish to create.

It is well recognised in psychology that music has affective connotations and that musical stimuli can modify affective states. The aim of this study was to assess the affective connotations of 120 fifteen-second musical excerpts, covering both modern musical genres such as pop, rock, jazz, rap/R&B and electronic music (5 x N = 20), and classical music ( N = 20). Expert judges used predetermined criteria to select excerpts with positive or negative valence that induced high arousal or low arousal. The excerpts were assessed by 50 undergraduate students (25 women) from different academic departments, aged between 18 and 28 years ( M = 21.46 years, SD = 1.85). They listened to all 120 fragments and rated them with respect to six dimensions: valence, arousal, dominance, origin, subjective significance and imageability. Analyses showed that ratings were reliable, with high split-half correlations and Cronbach’s alpha estimates. We did not identify any gender differences concerning affective reactions to the music. Some music genre specificity was found for all measures, and initial music preference appeared to shape affective ratings. The results presented here will be of interest to researchers working on musical perception and the influence of music on affective outcomes and emotional regulation.

PurposeAn important predictor of postsecondary academic success is an individual's reading comprehension skills. Postsecondary readers apply a wide range of behavioral strategies to process text for learning purposes. Currently, no tools exist to detect a reader's use of strategies. The primary aim of this study was to develop Read, Understand, Learn, & Excel, an automated tool designed to detect reading strategy use and explore its accuracy in detecting strategies when students read digital, expository text.MethodAn iterative design was used to develop the computer algorithm for detecting 9 reading strategies. Twelve undergraduate students read 2 expository texts that were equated for length and complexity. A human observer documented the strategies employed by each reader, whereas the computer used digital sequences to detect the same strategies. Data were then coded and analyzed to determine agreement between the 2 sources of strategy detection (i.e., the computer and the observer).ResultsAgreement between the computer- and human-coded strategies was 75% or higher for 6 out of the 9 strategies. Only 3 out of the 9 strategies–previewing content, evaluating amount of remaining text, and periodic review and/or iterative summarizing–had less than 60% agreement.ConclusionRead, Understand, Learn, & Excel provides proof of concept that a reader's approach to engaging with academic text can be objectively and automatically captured. Clinical implications and suggestions to improve the sensitivity of the code are discussed.Supplemental Materialhttps://doi.org/10.23641/asha.8204786

Abstract A study by Yaruss and Quesal (2002), based on responses from 134 of 239 ASHA accredited graduate programs, indicated that approximately 25% of graduate programs in the United States allow students to earn their degree without having coursework in fluency disorders and 66% of programs allow students to graduate without clinical experience treating people who stutter (PWS). It is not surprising that many clinicians report discomfort in treating PWS. This cross-sectional study compares differences in beliefs about the cause of stuttering between freshman undergraduate students enrolled in an introductory course in communicative disorders and graduate students enrolled and in the final weeks of a graduate course in fluency disorders.

Purpose Future speech-language pathologists are often unprepared in their academic training to serve the communicative and cognitive needs of older adults with dementia. While negative attitudes toward older adults are prevalent among undergraduate students, service learning has been shown to positively affect students' attitudes toward older adults. TimeSlips is an evidence-based approach that has been shown to improve health care students' attitudes toward older adults. The purpose of this study is to explore the change in attitudes in speech-language pathology students toward older adults using TimeSlips in service learning. Method Fifty-one students participated in TimeSlips service learning with older adults and completed the Dementia Attitude Scale (DAS) before and after service learning. In addition, students completed a reflection journal. The DAS data were analyzed using nonparametric statistics, and journal entries were analyzed using a qualitative analysis approach. Results The service learners exhibited a significant increase in positive attitude as indexed on the DAS. The reflective journal entries supported the positive change in attitudes. Conclusions A noticeable attitude shift was indexed in reflective journals and on the DAS. TimeSlips is an evidence-based, patient-centered approach well suited to address challenges in the preparation of Communication Sciences and Disorders students to work with the growing population of older adults.

To better prepare the professionals and scholars of tomorrow in the field of communication sciences and disorders (CSD), a research project in which undergraduate students collected and analyzed language samples of child-parent dyads is presented. Student researchers gained broad and discipline-specific inquiry skills related to the ethical conduct of research, the literature review process, data collection using language assessment techniques, language sample analysis, and research dissemination. Undergraduate students majoring in CSD developed clinical research knowledge, skills, and dispositions necessary for future graduate level study and professional employment. In addition to the benefits of student growth and development, language samples collected through this project are helping to answer research questions regarding communicative turn-taking opportunities within the everyday routines of young children, the effects of turn-taking interactions on language development, and the construct validity of language sampling analysis techniques.

There is a growing demand for bilingual services in speech-language pathology and audiology. To meet this growing demand, and given their critical role in the recruitment of more bilingual professionals, higher education institutions need to know more about bilingual students' impression of Communication Sciences and Disorders (CSD) as a major. The purpose of this qualitative study was to investigate bilingual and monolingual undergraduate students' perceptions of the CSD major. One hundred and twenty-two students from a large university located in a highly multicultural metropolitan area responded to four open-ended questions aimed at discovering students' major areas of interest (and disinterest) as well as their motivations for pursuing a degree in CSD. Consistent with similar reports conducted outside the United States, students from this culturally diverse environment indicated choosing the major for altruistic reasons. A large percentage of participants were motivated by a desire to work with children, but not in a school setting. Although 42% of the participants were bilingual, few indicated an interest in taking an additional course in bilingual studies. Implications of these findings as well as practical suggestions for the recruitment of bilingual students are discussed.

Background: Deliberate self-harm (DSH) occurs with high frequency among clinical and nonclinical youth populations. Although depression has been consistently linked with the behavior, not all depressed individuals engage in DSH. Aims: The current study examined maladaptive coping strategies (i.e., self-blame, distancing, and self-isolation) as mediators between depression and DSH among undergraduate students. Methods: 202 students from undergraduate psychology courses at a private university in Southern California (77.7% women) completed anonymous self-report measures. Results: A hierarchical regression model found no differences in DSH history across demographic variables. Among coping variables, self-isolation alone was significantly related to DSH. A full meditational model was supported: Depressive symptoms were significantly related to DSH, but adding self-isolation to the model rendered the relationship nonsignificant. Limitations: The cross-sectional study design prevents determination of whether a casual relation exists between self-isolation and DSH, and obscures the direction of that relationship. Conclusions: Results suggest targeting self-isolation as a means of DSH prevention and intervention among nonclinical, youth populations.

Background: Our laboratory recently confronted this issue while conducting research with undergraduate students at the University of Waterloo (UW). Although our main objective was to examine cognitive and genetic features of individuals with schizotypal personality disorder (SPD), the study protocol also entailed the completion of various self-report measures to identify participants deemed at increased risk for suicide. Aims and Methods: This paper seeks to review and discuss the relevant ethical guidelines and legislation that bear upon a psychologist’s obligation to further assess and intervene when research participants reveal that they are at increased risk for suicide. Results and Conclusions: In the current paper we argue that psychologists are ethically impelled to assess and appropriately intervene in cases of suicide risk, even when such risk is revealed within a research context. We also discuss how any such obligation may potentially be modulated by the research participant’s expectations of the role of a psychologist, within such a context. Although the focus of the current paper is on the ethical obligations of psychologists, specifically those practicing within Canada, the relevance of this paper extends to all regulated health professionals conducting research in nonclinical settings.
