Further examination of the treatment of multiply controlled inappropriate mealtime behavior

We systematically replicated Bachmeyer et al. (2009) by examining extinction procedures matched to each function, individually and in combination, to treat the food or liquid refusal of 4 children diagnosed with a feeding disorder whose inappropriate mealtime behavior was maintained by multiple functions (i.e., escape and attention). Previous research suggests that adding differential reinforcement to extinction procedures may result in better treatment outcomes. Therefore, we added differential reinforcement to extinction procedures matched to each function. Differential reinforcement and extinction matched only to escape or attention resulted in low rates of inappropriate mealtime behavior and high, stable levels of acceptance for only 1 child. Consistent with Bachmeyer et al., inappropriate mealtime behavior decreased, and acceptance increased for the remaining 3 children only after we matched differential reinforcement and extinction procedures to both escape and attention.     

奖惩对注意缺陷多动障碍儿童情感决策的影响

采用简化版儿童赌博任务,其中操纵了奖励和惩罚的强度,探察两种亚型（注意缺陷型和混合型）ADHD儿童的情感决策能力,同时采集儿童在任务中的皮肤电活动以探析ADHD儿童在情感决策中的生理机制。结果发现,在不同的奖惩强度下,ADHD儿童情感决策模式不同,在即刻奖励条件下,ADHD儿童情感决策的能力明显弱于正常对照组儿童,倾向于不利选择,所产生的预测性皮电振幅也明显低于正常对照组;在即刻惩罚条件下,ADHD儿童的情感决策能力未见异常。两种亚型ADHD儿童的表现模式相似。上述结果证明,ADHD儿童仅存在对奖励的异常敏感性,并确实影响了其决策能力,而其回避惩罚的能力正常。两种亚型ADHD儿童存在的问题相似     

Utilizing in-vivo feedback for caregiver training of pediatric feeding protocols

Researchers have used multicomponent behavioral skills training packages including written and verbal instructions, modeling, rehearsal, and feedback when teaching caregivers to implement pediatric feeding treatment protocols (e.g., Anderson & McMillan, 2001; Seiverling et al., 2012). Some investigators have shown that fewer behavioral skills training components may be necessary for effective training (e.g., Mueller et al., 2003; Pangborn et al., 2013). We examined the use of in-vivo feedback following written instructions to train caregivers to implement pediatric feeding treatment protocols using a multiple baseline design across 3 caregiver dyads. Correct implementation of the feeding treatment procedures was low during baseline (written instructions only), increased with only the addition of in-vivo feedback, and remained high during follow-up sessions for all caregivers. Results are discussed in terms of clinical implications and caregiver satisfaction.     

Further evaluation of modified‐bolus‐placement methods during initial treatment of pediatric feeding disorders

Children with feeding disorders might pack or expel food when they lack the oral‐motor skills, the motivation, or both, to swallow. Bolus placement directly on the tongue with a Nuk (e.g., Milnes et al., 2019) or flipped spoon (e.g., Sharp et al., 2010) is a treatment that researchers generally implement after such behavior emerges (e.g., Girolami et al., 2007). However, Wilkins et al. (2014) tested the relative efficacy of Nuk presentation and upright‐spoon presentation during initial treatment of pediatric feeding disorders. In the current study, we compared the effects of (a) upright‐spoon presentation; (b) Nuk presentation; and (c) flipped‐spoon presentation on two product measures of swallowing: 15‐ and 30‐s mouth clean, and expulsion during the initial treatment of feeding disorders with 5 children. We also monitored lip closure during bite presentation and following bolus placement. Nuk presentation produced the highest levels of mouth clean and the lowest rates of expels relative to upright‐spoon presentation and flipped‐spoon presentation. We discuss potential reasons why modified‐bolus‐placement methods improved feeding behavior and how measures of oral‐motor skills might predict its necessity during initial treatment.     

Bottom-up and top-down dynamics in young children's executive function: Labels aid 3-year-olds’ performance on the Dimensional Change Card Sort

Executive function (EF) improves between the ages of 3 and 5 and has been assessed reliably using the Dimensional Change Card Sort (DCCS), a task in which children first sort bivalent cards by one dimension (e.g., shape) and then are instructed to sort by a different dimension (e.g., color). Three-year-olds typically perseverate on the pre-switch dimension, whereas 5-year-olds switch flexibly. Labeling task stimuli can facilitate EF performance (0110 and 0060), but the nature of this effect is unclear. In 3 experiments we examined 2 hypotheses deriving from different theoretical perspectives: first, that labels facilitate performance in a more bottom-up fashion, by biasing attention to relevant task rules (Kirkham et al., 2003); and second, that labels aid performance in a more top-down fashion by prompting reflection and an understanding of the hierarchical nature of the task (Zelazo, 2004). Children performed better on the DCCS when labels referred to the relevant sorting dimension (Experiment 1). This was a function of the content of the labels rather than the change in auditory signal across phases (Experiment 2). Furthermore, labeling the opposite dimension only did not have a symmetrically negative effect on performance (Experiment 3). Together, these results suggest external, verbal labels bias children to attend to task-relevant information, likely through interaction with emerging top-down, endogenous control.     

Developmental differences in children’s interpersonal emotion regulation

Previous research on interpersonal emotion regulation (ER) in childhood has been rather unsystematic, focusing mainly on children’s prosocial behaviour, and has been conducted in the absence of an integrative emotion theoretical framework. The present research relied on the interpersonal affect classification proposed by Niven et al. (Emotion, 9:498–509, 2009) to investigate children’s use of different interpersonal ER strategies. The study drew on two samples: 180 parents of children aged between 3 and 8 years reported about a situation where their child was able to change what another person was feeling in order to make them feel better. In addition, 126 children between 3- and 8-years old answered two questions about how they could improve others’ mood. Results from both samples showed age differences in children’s use of interpersonal ER strategies. As expected, ‘affective engagement’ (i.e., focusing on the person or the problem) and ‘cognitive engagement’ (i.e., appraising the situation from a different perspective) were mainly used by 7–8 years-old, whereas ‘attention’ (i.e., distracting and valuing) was most used by 3–4 and 5–6 years-old. ‘Humor’ (i.e., laughing with the target) remained stable across the different age groups. The present research provides more information about the developmental patterns for each specific interpersonal emotion regulation strategy.     

The effects of variable-time delivery of food items and praise on problem behavior reinforced by escape

Prior research indicates that reinforcement of an appropriate response (e.g., compliance) can produce concomitant reductions in problem behavior reinforced by escape when problem behavior continues to produce negative reinforcement (e.g., Lalli et al., 1999). These effects may be due to a preference for positive over negative reinforcement or to positive reinforcement acting as an abolishing operation, rendering demands less aversive and escape from demands less effective as negative reinforcement. In the current investigation, we delivered a preferred food item and praise on a variable-time 15-s schedule while providing escape for problem behavior on a fixed-ratio 1 schedule in a demand condition for 3 participants with problem behavior maintained by negative reinforcement. Results for all 3 participants showed that variable-time delivery of preferred edible items reduced problem behavior even though escape continued to be available for these responses. These findings are discussed in the context of motivating operations.     

The effectiveness of and preschoolers' preferences for variations of multiple-schedule arrangements

Multiple schedules of reinforcement have been used to teach children to recruit attention only when it is available, thereby minimizing disruptive requesting during instructional activities. This procedure involves alternating periods of continuous reinforcement (CRF) with periods of extinction and correlating each period with a distinct and continuous discriminative stimulus. The present study evaluated the effectiveness of and children's preferences for multiple schedules in which (a) two different stimuli, one correlated with reinforcement (S+) and another correlated with extinction (S-), were presented; (b) only an S+ was presented (i.e., no stimulus was correlated with extinction), and (c) neither an S+ nor an S- was presented (i.e., a mixed schedule). S+/S- and S+ arrangements were similarly effective for 7 children, but 3 preferred the S+/S- condition and 4 preferred the S+ condition. Correlational analyses suggested that children who responded more effectively given the S- (discrimination indexes were relatively high) preferred the S+/S- condition, whereas children who responded less effectively given the S- preferred the S+ condition. The implications of these findings for arranging multiple schedules for social responses are discussed.     

Universality and context-specificity in early executive function development

A renewed interest in early executive function (i.e., EF or the conscious control of thought and behavior) development has led several research groups to suggest that EF may be emerging and is less coordinated (e.g., showing few relations between tasks) in the first few years (Devine et al., 2019; Gago Galvagno et al., 2021; Johansson et al., 2016; Miller & Marcovitch, 2015; Ribner et al., 2022). This potentially universal development in EF does not exclude the possibility that EF may also differ across context (e.g., Gago Galvagno et al., 2021; Lohndorf et al., 2019; Tran et al., 2015) reflecting unique strengths and development built within one’s sociocultural environment. The present paper explores potential universal and context-specific early EF developments by focusing on three aims: (1) reviewing work on EF within the first two years of life that may speak to potential universality in the measurement, structure, growth, stability, and conceptualization of early EF (2) reviewing research that may speak to how the sociocultural context may play a role in context-specific development within early EF and (3) examining potential developmental EF frameworks for understanding universal and context-specific developments of early EF within context.     

Evaluation of the rate of problem behavior maintained by different reinforcers across preference assessments

The rates of problem behavior maintained by different reinforcers were evaluated across 3 preference assessment formats (i.e., paired stimulus, multiple-stimulus without replacement, and free operant). The experimenter administered each assessment format 5 times in a random order for 7 children with developmental disabilities whose problem behavior was maintained by attention, tangible items, or escape. Results demonstrated different effects related to the occurrence of problem behavior, suggesting an interaction between function of problem behavior and assessment format. Implications for practitioners are discussed with respect to assessing preferences of individuals with developmental disabilities who exhibit problem behavior.     

Evaluating backward chaining methods on vocational tasks by adults with developmental disabilities

Backward chains are widely used to teach complex skills to individuals with developmental disabilities. Implementation of chaining procedures may vary regarding untaught steps and there is little to guide practitioners in the selection of chaining procedures. Moreover, there is a dearth of research evaluating effectiveness and efficiency of procedural variations of behavior chains. The purpose of this study was to extend previous research by evaluating the effectiveness, efficiency, and preference for four procedural variations (i.e., teacher‐completion, participant‐completion, no‐completion, and a control condition) of backward chains across vocational tasks with adults with developmental disabilities. Although procedural variations effectively established vocational skills, the participant‐completion procedure (in which the instructor implemented a least‐to‐most prompt hierarchy during all untrained steps in the chain) was the most efficacious backward chaining procedural variation and efficient in terms of sessions to mastery. The no‐completion procedure (in which the instructor completed all untrained steps in the chain out of view of the participant) was least efficient across trials, sessions, errors, and total duration to mastery. One participant preferred the no‐completion condition while the other two participants showed an initial preference for the teacher‐completion condition that changed to preference for the no‐completion condition. Vocational skills maintained 1‐ and 4‐weeks postmastery. Stakeholders rated goals, procedures, and outcomes as socially valid.     

Teaching children with autism to mand for social information

We replicated Shillingsburg et al. (2018) by teaching children with autism to mand for social information while analyzing the variables influencing the emission of mands. We presented questions about a social partner that were known and observable (e.g., “What is Robin doing?”), known but unobservable (i.e., questions for which an intraverbal response had previously been taught, such as, “Where does Robin work?”), or unknown (e.g., “What is Robin's favorite food?”). Correct answers were reinforced across all conditions. During treatment, we prompted children to mand for information from the social partner following only unknown questions. All children acquired mands for social information and answered previously unknown questions correctly after manding for social information and 3 of 4 participants emitted mands to novel social partners, including a peer with autism.     

Idiosyncratic effects of interviewer behavior on the accuracy of children's responses

Children are interviewed to provide information about past events in various contexts (e.g., police interviews, court proceedings, therapeutic interviews). During an interview, various factors may influence the accuracy of children's responses to questions about recent events. However, behavioral research in this area is limited. Sparling et al. (2011) showed that children frequently provided inaccurate responses to questions about video clips they just watched depending on the antecedents (i.e., the way a question was asked) and consequences (i.e., the response of the interviewer to their answers). In the current study, we replicated and extended the procedures reported by Sparling et al. and found that two of five children were sensitive to the various antecedents and consequences that we manipulated. Our findings indicate a need for more research in this area to determine the relevant environmental variables that affect children's response accuracy.     

The effects of a behavioral skills training and general‐case training package on caregiver implementation of a food selectivity intervention

We used behavioral skills training with general‐case training to teach 3 caregivers to implement a behavioral feeding intervention with their children. The percentage of correctly performed steps of the feeding intervention increased for all 3 caregivers and was maintained at follow‐up. For all 3 children, the number of bites consumed increased and the number of bites with inappropriate mealtime behavior decreased across treatment. Increases in bites consumed and bites without behavior problems were maintained for 2 participants at follow‐up.     

Effects of two levels of procedural fidelity with constant time delay on children's learning

The purpose of this study was to compare the effects of constant time delay delivered with high procedural fidelity to constant time delay with high procedural fidelity on all variables except delivery of the controlling prompt (i.e., on a mean of 44% of the trials, the controlling prompt was not delivered when it should have been provided). Six preschool children with disabilities were taught to identify photographs in two alternating conditions (e.g., high procedural fidelity and low procedural fidelity). An adapted alternating treatments design was used to evaluate the instructional conditions on the effectiveness and efficiency of instruction. In addition, daily measures were taken of the teacher's implementation of each step of the constant time delay procedures which indicated that the two conditions were implemented as planned. The results indicate that both conditions were effective for four children; for three of these, the high procedural fidelity condition resulted in more efficient learning. For the fifth child, the high-fidelity condition resulted in criterion level responding, but the low fidelity condition did not. However, when the high fidelity procedure and trial-by-trial reinforcement were used for the low-fidelity stimuli, these also were acquired. For the sixth child, neither procedure was effective; thus, the high fidelity condition was used alone and resulted in learning. The results are discussed in terms of using the constant time delay procedure and studying the procedural fidelity of other strategies.     

An evaluation of parent preference for prompting procedures

Parent participation in intervention can enhance intervention efficacy and promote generalization of skills across settings. Thus, parents should be trained to implement behavioral interventions. The purpose of the current investigation was to evaluate parent preference for and acceptability of 3 commonly used prompting procedures. We trained parents of children with disabilities to use 3 empirically validated prompting strategies (i.e., least-to-most, most-to-least, and a progressive-prompt delay). Once the parent reached the mastery criteria with each prompting procedure, we evaluated his/her preference for each of the procedures using a concurrent-chains arrangement. We also measured treatment acceptability of all procedures throughout the study. All participants met the mastery criteria for each of the prompting procedures and showed a preference for least-to-most prompting. Results suggest parents' acceptability of procedures prior to training were different than posttraining/post-child practice. In addition, acceptability rating scores obtained at the end of the investigation corresponded to preference of intervention during the concurrent-chains arrangement. The results demonstrate the benefits of objective measures for studying preference for behavioral, skill-acquisition procedures.     

Noncontingent and differential reinforcement in the treatment of pediatric feeding problems

We conducted functional analyses of the inappropriate mealtime behavior of 5 children diagnosed with feeding problems. Then, we compared the effects of differential and noncontingent reinforcement, and the relative effects of escape extinction with and without differential or noncontingent reinforcement, when escape extinction appeared necessary. Both reinforcement procedures were effective without escape extinction to treat food refusal for 1 child, but only differential reinforcement was effective without escape extinction to treat the child's liquid refusal. Escape extinction was necessary for 4 of 5 children. The addition of positive reinforcement resulted in beneficial effects (i.e., more stable acceptance, decreased inappropriate mealtime behavior or negative vocalizations) with 3 of 4 children. With escape extinction, differential reinforcement was more effective to treat food refusal for 2 children and noncontingent reinforcement was more effective for 1 child.     

A comparison of isolated and synthesized contingencies in functional analyses

Recently, researchers have compared the utility of isolated versus synthesized contingencies in functional analysis (FA) methodology (e.g., Fisher et al., 2016; Slaton et al., 2017). A limitation of these studies is that there were other differences across FA methodologies (e.g., design, contingency) that did not allow for isolation of the influence of isolated versus synthesized contingencies. Therefore, the current study compared outcomes of FAs that involved isolated versus synthesized contingencies for problem behavior of 5 children while controlling for these other differences across FAs (Experiment 1). Next, the current study compared the effects of interventions based on the functions identified in the isolated and synthesized contingencies for each participant (Experiment 2). Results indicated isolated contingency FAs produced differentiated responding for 1 or both functions for all 5 participants, and there were little to no differences between treatments informed by isolated and synthesized contingency FAs.     

Further investigation of increasing vocalizations of children with autism with a speech-generating device

We replicated and extended the findings of Gervarter et al. (2016) by using prompting and reinforcement to produce increased vocal speech with 3 young children diagnosed with autism spectrum disorder (ASD) who used a speech generating device (SGD). We extended Gervarter et al. by adopting a more robust experimental design, conducting session-by-session preference assessments, and measuring the emergence of novel vocalizations. The frequency of vocalizations increased for all 3 participants after the introduction of an echoic prompt. These results suggest that SGD-based interventions may lead to increased vocal output for children with ASD.     

Work Status Congruence’s Relation to Employee Attitudes and Behaviors: The Moderating Role of Procedural Justice

Purpose  

The purpose of this study is to explore procedural justice as a boundary condition of work status congruence’s (WSC) relationships with organizational commitment and organizational citizenship behavior (OCB). WSC is defined as the degree to which an employee’s schedule, shift, full-time or part-time status, and number of working hours, match his or her preferences (Holtom et al. in J Appl Psychol 86:80–93, 2002). This exploration is grounded in the outcome favorability–procedural justice interaction literature (e.g., Brockner in Acad Manag Rev 27:58–76, 2002).
