Distal rhythm influences whether or not listeners hear a word in continuous speech: Support for a perceptual grouping hypothesis

Due to extensive variability in the phonetic realizations of words, there may be few or no proximal spectro-temporal cues that identify a word’s onset or even its presence. Dilley and Pitt (2010) showed that the rate of context speech, distal from a to-be-recognized word, can have a sizeable effect on whether or not a word is perceived. This investigation considered whether there is a distinct role for distal rhythm in the disappearing word effect. Listeners heard sentences that had a grammatical interpretation with or without a critical function word (FW) and transcribed what they heard (e.g., are in Jill got quite mad when she heard there are birds can be removed and Jill got quite mad when she heard their birds is still grammatical). Consistent with a perceptual grouping hypothesis, participants were more likely to report critical FWs when distal rhythm (repeating ternary or binary pitch patterns) matched the rhythm in the FW-containing region than when it did not. Notably, effects of distal rhythm and distal rate were additive. Results demonstrate a novel effect of distal rhythm on the amount of lexical material listeners hear, highlighting the importance of distal timing information and providing new constraints for models of spoken word recognition.     

Shadow People: A Counter Visual of Those Who Use Methamphetamine

This photo essay offers a counter visual to the common images of people who use methamphetamine (meth). Images of meth users found in the media and in anti-meth campaigns typically paint them as one-dimensional actors who have sacrificed their health, families, and lives for their drug of choice. Such depictions contribute to the stigmatization and demonization of users, which can ultimately impede their recovery. Here, we provide photographs of men who previously cooked methamphetamine but who were in treatment at the time the photographs were taken. The photographs are captioned with quotes from the men to show some of the range of attractions for using, the hazards of chronic use, and the struggles to live free from meth. Our hope is that these images and brief quotes will help to show the complexity of these peoples’ lives.     

What Happens When Therapists Feel Bored or Anxious? A Qualitative Study of Distracting Self-Awareness and Therapists' Management Strategies

Using a qualitative methodology, we investigated novice and experienced therapists' experiences of and strategies for managing distracting self-awareness. We found that novice therapists were most aware of anxiety and critical self-talk, whereas experienced therapists were most aware of boredom and outside distracters. In addition, although therapists tended to manage distracting self-awareness through self-coaching and refocusing on the client, novice therapists specifically mentioned managing problematic self-awareness through self-disclosure. In contrast, experienced therapists tended to manage problematic self-awareness by using thought stopping techniques. The results provide new avenues for examining therapists' in-session experiences and for investigating the effectiveness of different management strategies.     

Altering the rhythm of target and background talkers differentially affects speech understanding

Three experiments investigated listeners’ ability to use speech rhythm to attend selectively to a single target talker presented in multi-talker babble (Experiments 1 and 2) and in speech-shaped noise (Experiment 3). Participants listened to spoken sentences of the form “Ready [Call sign] go to [Color] [Number] now” and reported the Color and Number spoken by a target talker (cued by the Call sign “Baron”). Experiment 1 altered the natural rhythm of the target talker and background talkers for two-talker and six-talker backgrounds. Experiment 2 considered parametric rhythm alterations over a wider range, altering the rhythm of either the target or the background talkers. Experiments 1 and 2 revealed that altering the rhythm of the target talker, while keeping the rhythm of the background intact, reduced listeners’ ability to report the Color and Number spoken by the target talker. Conversely, altering the rhythm of the background talkers, while keeping the target rhythm intact, improved listeners ability to report the Color and Number spoken by the target talker. Experiment 3, which embedded the target talker in speech-shaped noise rather than multi-talker babble, similarly reduced recognition of the target sentence with increased alteration of the target rhythm. This pattern of results favors a dynamic-attending theory-based selective-entrainment hypothesis over a disparity-based segregation hypothesis and an increased salience hypothesis.
