A new look at “the hard problem” of bilingual lexical access: evidence for language-switch costs with univalent stimuli

Considerable work has used language-switching tasks to investigate how bilinguals manage competition between languages. Language-switching costs have been argued to reflect persisting inhibition or persisting activation of a non-target language. However, these costs might instead reflect the use of bivalent stimuli (i.e. pictures or digits that can be responded to in either language). That is, language-switching costs may simply reflect a cost of selecting the task-appropriate response for a given item and so may not be reflective of bilingual lexical access [Finkbeiner, M., Almeida, J., Janssen, N., & Carramaza, A. (2006). Lexical selection in bilingual speech production does not involve language suppression. Journal of Experimental Psychology: Learning, Memory, and Cognition, 32(5), 1075–1089]. The present study addresses this concern by having Chinese/English bilinguals switch between languages in response to inherently univalent stimuli (English words and Chinese Characters) as well as lexically univalent, but orthographically bivalent, stimuli (English words and Chinese Pinyin). Speakers showed switch costs when naming both univalent and orthographically bivalent stimuli, showing that switch costs can be found even with inherently univalent stimuli.     

The moment‐to‐moment pitch dynamics of child‐directed speech shape toddlers’ attention and learning

Young children have an overall preference for child‐directed speech (CDS) over adult‐directed speech (ADS), and its structural features are thought to facilitate language learning. Many studies have supported these findings, but less is known about processing of CDS at short, sub‐second timescales. How do the moment‐to‐moment dynamics of CDS influence young children's attention and learning? In Study 1, we used hierarchical clustering to characterize patterns of pitch variability in a natural CDS corpus, which uncovered four main word‐level contour shapes: ‘fall’, ‘rise’, ‘hill’, and ‘valley’. In Study 2, we adapted a measure from adult attention research—pupil size synchrony—to quantify real‐time attention to speech across participants, and found that toddlers showed higher synchrony to the dynamics of CDS than to ADS. Importantly, there were consistent differences in toddlers’ attention when listening to the four word‐level contour types. In Study 3, we found that pupil size synchrony during exposure to novel words predicted toddlers’ learning at test. This suggests that the dynamics of pitch in CDS not only shape toddlers’ attention but guide their learning of new words. By revealing a physiological response to the real‐time dynamics of CDS, this investigation yields a new sub‐second framework for understanding young children's engagement with one of the most important signals in their environment.     

Effective remote staff training of objective session notes

Session notes are a required component of documenting behavior analytic sessions. The direct training of writing objective session notes is important to the success of direct line staff completing adequate documentation and meeting requirements set forth by agencies, certification boards, and insurance funders. However, in‐person training is not always immediately available due to contextual restrictions. This study evaluated the effectiveness of implementing the teaching interaction procedure when training staff remotely to objectively document client progress within session notes. Three Registered Behavior Technicians? (RBT®s) were trained via telehealth to complete session notes objectively. Results showed that all 3 participants met the mastery criterion during probes measuring the objective documentation of home‐based behavior analytic sessions. These findings suggest that a training package, such as the teaching interaction procedure, can be effectively implemented remotely when conducting staff training.

Using a chaser to decrease packing in children with feeding disorders

Packing is a problematic mealtime behavior that is characterized by pocketing or holding solids or liquids in the mouth without swallowing. In the current study, we examined the effects of a chaser, a liquid or solid consistently accepted and swallowed by the child, to decrease packing of solid foods in 3 children with feeding disorders. During the chaser procedure, the therapist presented the chaser immediately for 2 children or 15 s after each bite presentation for 1 child. The chaser was effective in decreasing packing for all 3 children. The results are discussed in terms of the clinical importance of the findings and directions for future research.     

Childhood Psychological Trauma and First‐Year College Students' Substance Dependence

First‐year college students (N= 143) completed the Substance Abuse Subtle Screening Inventory‐3 and a questionnaire about childhood traumatic experiences. As the number of traumatic experiences increases, so does the likelihood of substance use in college.     

“I Fired My Last Doctor for Not Taking Me Seriously”: Collaborating With a Difficult Medical Patient in a Multidisciplinary Primary Care Facility

We present the case of a multidisciplinary primary care assessment of a 32-year-old woman with multiple medical and psychological complaints. Following the collaborative care model, this assessment was conducted by a team consisting of a clinical health psychologist, Dr. J. L. Skillings, and a family physician, Dr. W. J. Murdoch. We describe the primary care environment in which this referral was made including the methods that were utilized to insure a successful professional collaboration. We report the results and recommendations from a comprehensive biopsychosocial assessment; we place emphasis on the psychological diagnosis and pain symptoms. We also describe the feedback session in which the assessment results were provided to the patient and her spouse by both physician and psychologist. Multiperspective commentary about the assessment is offered by the patient and her husband as well as the physician and psychologist assessors.     

Psychotherapy Appointment No-Shows: Clinicians’ Approaches

Missed psychotherapy appointments and eleventh hour cancellations contribute to financial burdens, reduced scheduling efficiency, and lowered effectiveness of the therapeutic services delivered. This paper attempts to explore more specific clinical process factors related to patient no-shows. Psychotherapists and their patients in the outpatient psychiatry department of a public safety-net hospital were surveyed to examine how frequently patients missed scheduled psychotherapy appointments and for what reasons. Clinicians with the lowest rates of patient no-shows (n = 12) were asked to discuss their approaches to psychotherapy attendance and provided clinical examples. Clinicians’ responses were thematically grouped into five aspects of negotiating missed appointments and no-shows. Clinicians identified the importance of improving patient motivation, developing a positive therapeutic alliance, setting an established treatment frame, communicating about no-shows throughout the course of treatment, and maintaining their own scheduling accountability as important factors in their approaches to managing patient non-attendance.     

Vocal learning of a communicative signal in captive chimpanzees, Pan troglodytes

We hypothesized that chimpanzees could learn to produce attention-getting (AG) sounds via positive reinforcement. We conducted a vocal assessment in 76 captive chimpanzees for their use of AG sounds to acquire the attention of an otherwise inattentive human. Fourteen individuals that did not produce AG sounds during the vocal assessment were evaluated for their ability to acquire the use of an AG sound through operant conditioning and to employ these sounds in an attention-getting context. Nine of the 14 chimpanzees were successfully shaped using positive reinforcement to produce an AG sound. In a post-training vocal assessment, eight of the nine individuals that were successfully trained to produce AG sounds generalized the use of these newly acquired signals to communicatively relevant situations. Chimpanzees possess the ability to acquire the use of a communicative signal via operant conditioning and can generalize the use of this newly acquired signal to appropriate communicative contexts.
