Switching in the cocktail party: exploring intentional control of auditory selective attention

Using a novel variant of dichotic selective listening, we examined the control of auditory selective attention. In our task, subjects had to respond selectively to one of two simultaneously presented auditory stimuli (number words), always spoken by a female and a male speaker, by performing a numerical size categorization. The gender of the task-relevant speaker could change, as indicated by a visual cue prior to auditory stimulus onset. Three experiments show clear performance costs with instructed attention switches. Experiment 2 varied the cuing interval to examine advance preparation for an attention switch. Experiment 3 additionally isolated auditory switch costs from visual cue priming by using two cues for each gender, so that gender repetition could be indicated by a changed cue. Experiment 2 showed that switch costs decreased with prolonged cuing intervals, but Experiment 3 revealed that preparation did not affect auditory switch costs but only visual cue priming. Moreover, incongruent numerical categories in competing auditory stimuli produced interference and substantially increased error rates, suggesting continued processing of task-relevant information that often leads to responding to the incorrect auditory source. Together, the data show clear limitations in advance preparation of auditory attention switches and suggest a considerable degree of inertia in intentional control of auditory selection criteria.     

Response to MacIntosh’s Systematic Review of Psychoanalytic Couple Therapy: A Brief Note from the Classical Perspective

ABSTRACT

Working with couples from a classical perspective can be thought of as an oxymoron, unlike working from object relations and relational viewpoints, often seen to be the more natural fits. This article offers a fresh look at those parts of the classical perspective that relate very clearly to working with two partners in a couple. Freud’s theories in Three Essays on the Theory of Sexuality (1905) and On Narcissism (1914a) provide theoretical background for the work. Concepts such as transference (between partners, between the partner[s] and the therapist) and countertransference are shown to be manifested in complex ways with couples. Being mindful of unresolved developmental issues—for example, Oedipal and separation-individuation issues—which may have played a part in partner choice and in the resulting problems, allows the therapist to offer deep interpretations of within- and between-partner conflicts. Interestingly, unresolved Oedipal issues, particularly, may form an important part of the countertransference.     

People and objects affect the quality of vocalizations in infants with down syndrome

The vocalizations of eight infants with Down syndrome were recorded longitudinally in relation to different social and non-social contexts. The infants were observed biweekly from 8 to 24 weeks and monthly up to 40 weeks. At each visit the infants were presented with their mother, a female stranger, and a rattle puppet, each alternately active and passive. Each condition lasted 60 sec. The results showed that by 4 months of age, the infants produced different types of vocal sounds in relation to environmental contexts. They produced significantly more melodic (speechlike) sounds, vocalic (non-speechlike) sounds, and emotional (crying, laughing and fussing) sounds when facing people than objects. By 6 months of age, these utterances began to be distinguished between mother and female stranger and active and passive adults. However, within the communicative context the overall amount of vocalic (non-speechlike) sounds produced was larger than the amount of melodic (speechlike) sounds. It is suggested that this low output of melodic sounds in the overall vocal production of these infants may adversely affect the development of more appropriate vocal behaviour.

Ethics in Community-University-Artist Partnered Research: Tensions,Contradictions and Gaps Identified in an ‘Arts for Social Change’ Project

Academics from diverse disciplines are recognizing not only the procedural ethical issues involved in research, but also the complexity of everyday “micro” ethical issues that arise. While ethical guidelines are being developed for research in aboriginal populations and low-and-middle-income countries, multi-partnered research initiatives examining arts-based interventions to promote social change pose a unique set of ethical dilemmas not yet fully explored. Our research team, comprising health, education, and social scientists, critical theorists, artists and community-activists launched a five-year research partnership on arts-for-social change. Funded by the Social Science and Humanities Research Council in Canada and based in six universities, including over 40 community-based collaborators, and informed by five main field projects (circus with street youth, theatre by people with disabilities, dance for people with Parkinson’s disease, participatory theatre with refugees and artsinfused dialogue), we set out to synthesize existing knowledge and lessons we learned. We summarized these learnings into 12 key points for reflection, grouped into three categories: community-university partnership concerns (n?=?3), dilemmas related to the arts (n?=?5), and team issues (n?=?4). In addition to addressing previous concerns outlined in the literature (e.g., related to consent, anonymity, dangerous emotional terrain, etc.), we identified power dynamics (visible and hidden) hindering meaningful participation of community partners and university-based teams that need to be addressed within a reflective critical framework of ethical practice. We present how our team has been addressing these issues, as examples of how such concerns could be approached in community-university partnerships in arts for social change.     

小学生调节聚焦对生活满意度的影响:压力应对方式的中介作用

采用调节聚焦问卷、压力应对方式问卷和生活满意度问卷对北京市五所学校1174名小学生进行调查, 考察调节聚焦对小学生压力应对方式、生活满意度的影响, 并检验应对方式在调节聚焦和生活满意度之间的中介作用。结果发现:(1)促进定向对小学生生活满意度有显著正向预测作用, 预防定向对生活满意度有显著负向预测作用;(2)积极应对和促进定向更相关, 消极应对和预防定向更相关;(3)积极应对在促进定向和生活满意度之间起着完全中介的作用, 积极应对、消极应对均在预防定向和生活满意度之间起着部分中介的作用。     

Second language vocabulary level is related to benefits for second language listening comprehension under lower reverberation time conditions

The acoustic qualities of a room can have a deleterious effect on the quality of speech signals. The acoustic measurement of reverberation time (RT) has shown to impact second language (L2) speech comprehension positively when lower due to release from spectral and temporal masking effects as well as top-down processing factors. This auralization experiment investigated the benefits of better L2 vocabulary and executive function (updating) skills during L2 listening comprehension tests under shorter versus longer RT conditions (0.3 and 0.9?s). 57 bilingual university students undertook L2 vocabulary, number updating and L2 listening comprehension tests. After splitting groups into high/low vocabulary and updating groups, a mixed ANOVA was conducted. The high number updating group showed no significant differences or interactions in L2 listening comprehension than the lower number updating group across RT conditions. The high vocabulary group had 22% better L2 listening comprehension than the low vocabulary group in long RT, and 9% better in short RT. A significant benefit in L2 listening comprehension due to release from reverberation was only evident in the high vocabulary group. Results indicate that the benefit of good room acoustics for listening comprehension is greatest for those with better language (vocabulary) ability.     

Sculpting Present and Future: A Systemic Intervention Model Applied to Psychosomatic Families

We present a therapeutic intervention model for use with psychosomatic families. This method, the result of our extensive research on various psychosomatic disorders, uses family sculptures of the "present" and "future": each family member is requested to represent the family as it now "is," and how it "will be" in the future. We discuss the theoretical reasons for our choice of this method: (a) the opportunity to use a therapeutic language that is similar to the nonverbal language of the psychosomatic symptom, and (b) the usefulness of reinserting temporal dimensions into family systems that seem to have lost their evolutionary potential and to be in a sort of "time lock." Two clinical cases are discussed (a child with chronic asthma and an anorexic adolescent); the use of sculptures in both cases revealed the underlying problems and made positive therapeutic interventions possible. Finally, we point out how the use of sculpture as a therapeutic technique enables therapists to deal with multiple systemic levels.
