REVIEW
Mathijs Franssen, Nathalie Claes, Bram Vervliet, Tom Beckers, Dirk Hermans, Frank Baeyens
In two experiments, using an online conditioned suppression task, we investigated the possibility of reinstatement of extinguished feature-target compound presentations after sequential feature-positive discrimination training in humans. Furthermore, given a hierarchical account of Pavlovian modulation (e.g., Bonardi, 1998; Bonardi and Jennings, 2009), we predicted A-US reinstatement to be stronger than US-only reinstatement. In Experiment 1, participants learned a sequential feature-positive discrimination (X→A(+)|A(-)), which was subsequently extinguished (X→A(-))...

Recent theoretical and experimental studies suggest that in multisensory conditions, the brain performs a near-optimal Bayesian estimate of external events, giving more weight to the more reliable stimuli. However, the neural mechanisms responsible for this behavior, and its progressive maturation in a multisensory environment, are still insufficiently understood. The aim of this letter is to analyze this problem with a neural network model of audiovisual integration, based on probabilistic population coding-the idea that a population of neurons can encode probability functions to perform Bayesian inference...

In an operant serial feature-positive procedure, an occasion setter (OSX) signals that a response will be reinforced in the presence of second stimulus (e.g., a discriminative stimulus, A). During a transfer test, the OS is paired with a different discriminative stimulus. Experiment 1a tested transfer effects in a touchscreen-based spatial occasion setting task with pigeons. During training, four OSs (OSW, OSX, OSY, and OSZ) were paired on separate trials with landmark A (LMA) or B (LMB) and the opportunity for a reinforced response one location to the immediate left (R1) or right (R2) of the LM (OSW→LMA:R1, OSX→LMA:R2, OSY→LMB:R1, OSZ→LMB:R2)...

Clostridium difficile is an emerging cause of healthcare associated infections. In nine hospitals of an Italian Local Health Authority the episodes of C. difficile infection (CDI) were identified using the data registered by the centralized Laboratory Information System, from 2010 to 2015. CDI incidence (positive patients for A and/or B toxins per patients-days) was analysed per year, hospital, and ward. A number of cases approximately equivalent to the mean of identified cases per year were studied retrospectively to highlight the risk factors associated to CDI and their severity...

One of the key issues pertaining to the control of memory is to respond to a consistently changing environment or microbial niche present in it. Human cyclic AMP response element binding protein (CREB) transcription factor which plays a crucial role in memory has a homolog in C. elegans, crh-1. crh-1 appears to influence memory processes to certain extent by habituation of the host to a particular environment. The discrimination between the pathogen and a non-pathogen is essential for C. elegans in a microbial niche which determines its survival...

Sleep problems in toddlers occur in ∼40% of children and increase the likelihood of postnatal depression. Most sleep training in toddlers requires contact with a trained professional, and requires a parent to ignore their child's cries, causing distress to many children and parents, increasing attrition and leaving families untreated and at risk. This case study reports success in significantly ameliorating sleep reluctance and bedtime fears in a sleep disturbed toddler with a history of trauma. It uses a novel use of bedtime behaviour management with some positive reinforcement techniques, called the Boss of My Sleep book: a non-cry, online (thus readily and cheaply available without a trained professional) sleep intervention...

There is evidence for impaired selective learning mechanisms in individuals high in schizotypy. Overshadowing provides a direct test of selective learning based on cue salience and has previously been reported to be impaired in relation to schizotypy scores. The present study tested for overshadowing using food allergy and Lego construction task variants. Both variants used the same number of conditioned stimulus (CS) cues and the same number of learning trials. CS cues were trained in compound pairs or in isolation and overshadowing was subsequently tested on trials followed by negative versus positive outcomes...

Vasectomy is a highly effective and safe contraceptive method for couples who want to stop childbearing, but only 2.4% of men around the world use this method. We conducted an extensive review of the vasectomy research literature and programmatic reports, published between April 2005 and April 2015, to synthesize barriers and facilitators to vasectomy adoption. Of the more than 230 documents initially retrieved in our search, we ultimately included 75 documents in our review and synthesized the findings according to the Supply-Enabling Environment-Demand (SEED) Programming Model...

In several laboratory meetings, we discussed the challenges that face trainees in behavioral pharmacology. Major concerns, such as a difficult funding climate and limited academic job prospects were discussed at first. However, we decided to concentrate on ways to meet these challenges; versus focusing on negatives and listing gripes. Within this more constructive framework, we identified the importance of broadening training to aligned areas to enhance the capacity of behavioral pharmacologists to collaborate in multidisciplinary teams...

Laurel A Screven, Micheal L Dent
Mice often produce ultrasonic vocalizations (USVs) that sweep upwards in frequency from around 60 to around 80 kHz and downwards in frequency from 80 to 60 kHz. Whether or not these USVs are used for communication purposes is still unknown. Here, mice were trained and tested using operant conditioning procedures and positive reinforcement to discriminate between synthetic upsweeps and downsweeps. The stimuli varied in bandwidth, duration, and direction of sweep. The mice performed significantly worse when discriminating between background and test stimuli when the stimuli all occupied the same bandwidths...

Juliana Lopez Marulanda, Olivier Adam, Fabienne Delfour
Bottlenose dolphins are highly social cetaceans with an extensive sound production including clicks, burst-pulsed sounds, and whistles. Some whistles, known as signature whistles, are individually specific. These acoustic signatures are commonly described as being emitted in contexts of stress during forced isolation and as group cohesion calls. Interactions between humans and captive dolphins is largely based on positive reinforcement conditioning within several training/feeding sessions per day. Vocal behavior of dolphins during these interactions might vary...

BACKGROUND: Wearable activity trackers (trackers) are increasingly popular devices used to track step count and other health indicators. Trackers have the potential to benefit those in need of increased physical activity, such as adults who are older and face significant health challenges. These populations are least likely to purchase trackers and most likely to face challenges in using them, yet may derive educational, motivational, and health benefits from their use once these barriers are removed...

Aaron J Gruber, Rajat Thapa
The propensity of animals to shift choices immediately after unexpectedly poor reinforcement outcomes is a pervasive strategy across species and tasks. We report here that the memory supporting such lose-shift responding in rats rapidly decays during the intertrial interval and persists throughout training and testing on a binary choice task, despite being a suboptimal strategy. Lose-shift responding is not positively correlated with the prevalence and temporal dependence of win-stay responding, and it is inconsistent with predictions of reinforcement learning on the task...

BACKGROUND: Community health workers (CHWs) have the potential to reduce child mortality by improving access to care, especially in remote areas. Uganda has one of the highest child mortality rates globally. Moreover, rural areas bear the highest proportion of this burden. The optimal performance of CHWs is critical. In this study, we assess the performance of CHWs in managing malaria, pneumonia, and diarrhea in the rural district of Lira, in northern Uganda. DESIGNS: A cross-sectional mixed methods study was undertaken to investigate the performance of 393 eligible CHWs in the Lira district of Uganda...

CONTEXT: Patients with attention-deficit/hyperactivity disorder (ADHD) can be noncompliant, impulsive, and disruptive in an athletic training or physical rehabilitation facility. Athletic trainers (ATs) are valuable and essential health care providers for active patients with ADHD. However, for a patient with ADHD to have a successful outcome in a busy athletic training environment, the AT or health care provider must tailor the treatment setting to the patient's needs. OBJECTIVE: To educate and raise awareness among ATs about patients with ADHD and to provide ATs with strategies and tools that will allow them to treat patients with ADHD more effectively...

This study aimed to obtain an understanding of the self-rated health among community-dwelling elderly people in the north of Minas Gerais, identifying factors associated with negative self-rated health. We conducted a population-based cross-sectional study with two-stage random sampling. Data collection was carried out in the home of elderly people by trained staff who used questionnaires that had already been validated. To identify the variables associated with negative self-rated health, bivariate analyses were performed, followed by Poisson regression analysis...

Three experiments explored the utility of considering mechanisms of occasion setting for understanding patterning and biconditional discriminations - two more complex conditional discriminations in which the stimulus-outcome relations of occasion setting are embedded. In Experiment 1, rats were trained in an appetitive conditioning task with either a biconditional or a patterning discrimination using relatively brief CSs (10s) and differential outcomes as USs. In this study, rats learned the positive patterning task before they had learned negative patterning, and the biconditional task was the most difficult...

Anna J Swan, Matthew M Carper, Philip C Kendall
Stokes and Osnes (1989) outlined three principles to facilitate the generalization and maintenance of therapeutic gains. Use of functional contingencies, training diversely, and incorporating functional mediators were recommended. Our review, with most illustrations from studies of youth, updates Stokes and Osnes's original paper with a focus on evidence-based strategies to increase generalization of therapeutic gains across settings, stimuli, and time. Research since 1989 indicates that training for generalization by increasing the frequency of naturally occurring reinforcers for positive behaviors, and altering maladaptive contingencies that inadvertently reinforce problem behaviors, are associated with favorable treatment outcomes...
