“work ethic” in pigeons: Reward value is directly related to the effort or time required to obtain the reward

Stimuli associated with less effort or with shorter delays to reinforcement are generally preferred over those associated with greater effort or longer delays to reinforcement. However, the opposite appears to be true of stimuli thatfollow greater effort or longer delays. In training, a simple simultaneous discrimination followed a single peck to an initial stimulus (S+_FR1 S−_FR1) and a different simple simultaneous discrimination followed 20 pecks to the initial stimulus (S+_FR20 S−_FR20). On test trials, pigeons preferred S+_FR20 over S+_FR1 and S−_FR20 over S−_FR1. These data support the view that the state of the animal immediately prior to presentation of the discrimination affects the value of the reinforcement that follows it. This contrast effect is analogous to effects that when they occur in humans have been attributed to more complex cognitive and social factors.     

Benefits of recreational dance and behavior analysis for individuals with neurodevelopmental disorders: A literature review

Dance can be an entertaining experience that offers multiple benefits for those who participate. Unlike typically developing populations, studies examining benefits of recreational dance for individuals with neurodevelopmental disorders are limited. In this review, we conducted a literature search, where “dance” was cross‐listed with all neurodevelopmental disorders across five databases, yielding 19 articles. Twelve studies involved children and youth with neurodevelopmental disorders aged 3–19 years, two studies included both adolescents and adults aged 14–22 years, and five studies included adults aged 20–65 years. Given the effectiveness of applied behavior analysis in enhancing skill development, it is encouraging that eight studies explicitly identified behavioral components. Results suggest potential benefits of recreational dance across studies using self‐report and objective measures, but limited research with sound methodology exists. There is a need for controlled research with measurable outcomes to evaluate programs tailored to these populations to improve core challenges and secondary outcomes such as quality of life.     

Risk for injury in preschoolers: relationship to attention deficit hyperactivity disorder.

Parental ratings of preschoolers' risk for injury, direct assessment of preschoolers' behavior thought related to risk for injury (e.g., Inattention, impulsivity) and number of documented injuries were examined in preschoolers with Attention Deficit Hyperactivity Disorder (ADHD) and their non-ADHD peers (Control). Of preschoolers with ADHD, 58.3% exhibited behavior which placed them at-risk for physical injury (0% Control), and their performance was significantly poorer on clinic-based tests. Nonetheless, preschoolers with ADHD did not actually sustain significantly more injuries which warranted medical treatment in an emergency department. Although preschoolers with ADHD may be at increased risk for minor injuries, further research is needed to determine whether they more frequently sustain more serious injuries.     

The efficacy of a pilot pediatric cognitive remediation summer program to prepare for transition of care

This study assessed the efficacy of a time-sensitive cognitive remediation summer program (CRSP) that provided patients and their families with tools to help mitigate neurocognitive deficits and promote independence to foster precursor transition of medical care skills. A total of 38 participants (aged 9–15) were included in one of the CRSPs offered yearly from 2013 to 2016. A longitudinal design was employed and at each evaluation time point, one week before start of the CRSP (pre-testing) and within three weeks after the end of the program (post-testing)), participants were administered measures of executive functioning in addition to parent ratings of behavior, executive functioning, and adaptive skills (Year 1–Year 4). In Year 4, additional measures were collected, including parenting style and parent engagement and involvement in the program. Results from Year 1 to Year 4 (n = 35) demonstrated that participants in the CRSP showed significant improvement on neuropsychological testing in sustained and selective attention, planning, and cognitive flexibility. Robust changes in parent ratings of adaptive functioning from pre- to post-treatment were also found. Specific to Year 4 (n = 13), results revealed that participants showed improvement in levels of independence with at least one of the individualized goals focused on during the program. This study provided a systematic method to gauge the levels of instruction necessary to reach goals, a crucial tool in skill-teaching. Overall, our study provides evidence for the efficacy of the CRSP and validates a feasible intervention that can be integrated into standard of care for pediatric medical populations.

Televised social interaction and object learning in 14- and 18-month-old infants

We examined object learning in infants who viewed a televised adult speaking about a novel toy in videos that varied in the social cues provided. Novelty preference in following test trials differed as a function of televised social cues in 18-month-old, but not 14-month-old infants.     

A Cognitive-Behavioral Mindfulness Group Therapy Intervention for the Treatment of Binge Eating in Bariatric Surgery Patients

Binge eating is a negative indicator of post-surgical weight loss and health outcome in bariatric surgery patients (Hsu, Bentancourt, Sullivan, 1996). Cognitive-behavioral techniques and mindfulness-based practices have been shown to successfully treat binge eating (Agras, Telch, Arnow, Eldredge, & Marnell, 1997; Kristeller & Hallett, 1999). This report describes the development and implementation of a 10-week cognitive-behavioral mindfulness-based group intervention designed to reduce binge eating and address the specific needs of bariatric surgery patients. Posttreatment data showed improvement in binge eating symptoms, depressive symptomatology, and emotion regulation skills and increased motivation to change maladaptive eating behavior.     

Differential effects of happy,neutral, and sad still‐faces on 2‐, 4‐ and 6‐month‐old infants

The role of facial expression in the determination of infants' reaction to the sudden still‐face of a social partner was investigated. In a within subject design, 2, 4 and 6‐month‐old infants were tested in periods of normal interaction interspersed with periods of prolonged still‐face episodes in which the female adult social partner adopted either a happy, neutral, or sad static facial expression while maintaining eye contact with the infant. Proportion of infants' smiling and gazing at the social partner as indices of reaction from the various still‐face episodes reveal that, in comparison with same age control groups, four and six‐month‐old infants did not demonstrate any differential responses depending on either happy, neutral, and sad still‐faced expression. In contrast, two‐month olds demonstrated some evidence of a reduced still‐face effect in the happy still‐face condition. These results point to early developmental changes in the mechanisms underlying the still‐face phenomenon. We propose that by 4 months, and not prior, the reaction to still‐face episodes are essentially based on the detection of social contingencies. Copyright © 2002 John Wiley & Sons, Ltd.     

Joint attention and object learning in 5‐ and 7‐month‐old infants

We examined the effects of joint attention for object learning in 5‐ and 7‐month‐old infants. Infants interacted with an adult social partner who taught them about a novel toy in two conditions. In the Joint Attention condition, the adult spoke about the toy while alternating gaze between the infant and the toy, while in the Object Only condition, the adult looked to the toy and to a spot on the ceiling, but never at the infant. In the test trials following each social interaction, we presented infants with the ‘familiarization’ toy and a novel toy, and monitored looking times to each object. We found that 7‐month‐olds looked significantly longer to the novel toy following the Joint Attention relative to the Object Only condition, while 5‐month‐old infants did not show a significant difference across conditions. We interpret these results to suggest that joint attention facilitated 7‐month‐old infants' encoding of information about the familiarization object. Implications for the ontogeny of infant learning in joint attention contexts are discussed. Copyright © 2007 John Wiley & Sons, Ltd.
