A demonstration of higher‐order response class development in children

We evaluated a procedure for teaching two children, one typically developing and one with autism, a higher‐order generalized operant response class of unscrambling sight words. The procedures were efficacious in teaching the participants to unscramble words appearing in isolation and in the context of a sentence, with 98% of the presented discriminative stimuli novel to the participants.     

A comparison of prompting tactics to establish intraverbals in children with autism

We compared the efficacy of tact-to-intraverbal (i.e., using picture prompts) and echoic-to-intraverbal transfer-of-stimulus-control procedures to establish intraverbal responding in 3 boys (4 years old) with autism. For all 3 participants, the picture prompts resulted in fewer trials to criterion, but both prompting tactics were eventually effective.     

Resurgence of temporal patterns of responding

The resurgence of temporal patterns of key pecking by pigeons was investigated in two experiments. In Experiment 1, positively accelerated and linear patterns of responding were established on one key under a discrete-trial multiple fixed-interval variable-interval schedule. Subsequently, only responses on a second key produced reinforcers according to a variable-interval schedule. When reinforcement on the second key was discontinued, positively accelerated and linear response patterns resurged on the first key, in the presence of the stimuli previously correlated with the fixed- and variable-interval schedules, respectively. In Experiment 2, resurgence was assessed after temporal patterns were directly reinforced. Initially, responding was reinforced if it approximated an algorithm-defined temporal pattern during trials. Subsequently, reinforcement depended on pausing during trials and, when it was discontinued, resurgence of previously reinforced patterns occurred for each pigeon and for 2 of 3 pigeons during a replication. The results of both experiments demonstrate the resurgence of temporally organized responding and replicate and extend previous findings on resurgence of discrete responses and spatial response sequences.     

Age-Related and Situation-Related Social Desirability Responding Among Chinese Teachers

ABSTRACT

Social desirability responding (SDR) was affected by situation and age. However, most research is only concerned with overall SDR without considering the separation of impression management and self-deception. The purpose of this article is to explore the possible different effects of age and situation on the different components of SDR. A total of 158 teachers completed the BIDR at a 2 (high vs. low SDR situation) × 2 (20–29 vs. 30–39 years old) between-group experiment. The results of multivariate analyses, with gender and tenure controlled, suggested that the effects of age and situation on the four specific components were mixed. Impression management enhancement (IME) and denial (IMD) were significantly affected by situations. The older group had significantly higher self-deception enhancement (SDE) and IME scores than the younger one. Females had significantly higher IME scores than males. More age stages and the main effect of gender should be considered in the future.     

Relative preference for distinct reinforcers maintaining destructive behavior

The literature offers few recommendations for sequencing exposure to treatment conditions with individuals with multiply maintained destructive behavior. Identifying relative preference for the functional reinforcers maintaining destructive behavior may be one means of guiding that decision. The present study presents a preliminary attempt at developing a robust relative preference and reinforcer assessment for individuals with multiply maintained destructive behavior. Guided and free-choice trials were implemented in which participants chose between two multiple-schedule arrangements, each of which programmed signaled periods of isolated reinforcer availability and unavailability. Consistent participant choice and responding during free-choice trials was then used to thin the corresponding schedule of reinforcement. The results demonstrated a strong preference for one of the two functional reinforcers for all four participants, yet preferences differed across participants and were not well predicted by responding in prior analyses.     

Good design as design for good: exploring how design can be ethically and environmentally sustainable by co-designing an eco-hostel within a Mayan community

Designers acknowledge that their skills can assist the visualization and materialization of a desirable future and have gone as far as proposing that design can achieve societal change. Designing for a better world is associated with decreasing environmental depletion impacts while making good for both people and the environment, if possible. Evidently, this is a space where design deals with ethical matters, defining what is good or questioning if good has a universal meaning. This paper discusses the case of Aalto LAB Mexico's (ALM) Eco-hostel project, a practical and ethical design exploration. It shares the impressions of the design team when co-designing with(in) the Mayan community of ‘20 de Noviembre’ (20 Nov), located in Calakmul, Campeche, México. The Eco-hostel project was proposed as an element which can play a central role in achieving betterment of several aspects of the community's daily life. Several of those aspects were communicated by the inhabitants of 20 Nov, and some others were identified by ALM's experts. Whereas some universal principles were applicable to the construction, the context-centred approach of ALM generated a unique proposal, conceptualized to achieve harmony with the local environmental and cultural conditions.     

Evaluation of a treatment package to reduce rapid eating

We replicated and extended treatment procedures described by Lennox, Miltenberger, and Donnelly (1987) designed to reduce rapid eating. The participant was a 17-year-old girl with developmental disabilities who engaged in dangerously high rates of food ingestion. The procedure involved an adjusting differential-reinforcement-of-low-rate-responding (DRL) schedule, response blocking, and prompts. We evaluated a continuation of the treatment despite initial negative side effects that were similar to those reported by Lennox et al. Results showed that the treatment package was effective and negative side effects eventually decreased.     

The effects of magnitude and quality of reinforcement on choice responding during play activities

Three boys with autism participated in a study of the effects of magnitude and quality of reinforcement on choice responding. Two concurrent response alternatives were arranged: (a) to play in an area where a peer or sibling was located, or (b) to play in an area where there was no peer or sibling. During one condition, the magnitude (i.e., duration of access to toys) or quality (level of preference) of reinforcement provided for both responses was equal. During the other condition, the magnitude or quality of reinforcement was relatively greater for choosing the play area where the peer or sibling was located than the area where the peer or sibling was not located. Results showed that after repeated exposure to the unequal magnitude or quality condition, the participant increasingly allocated his responses to the play area where the peer or sibling was located. For 2 participants, this pattern of responding was maintained in the subsequent equal magnitude or quality condition. Overall, the analysis suggests that the dimensions of magnitude and quality of reinforcement can be arranged to influence choice responding in favor of playing near a peer or sibling rather than playing alone.     

GENERALIZED IMITATION AND RESPONSE-CLASS FORMATION IN CHILDREN WITH AUTISM

An experimental analysis of imitation was conducted to examine the influence of response topography on generalization of imitation across three response types. Four children with autism were presented with both reinforced training trials and nonreinforced probe trials of models from vocal, toy-play, and pantomime response types. The probe trials were used to examine generalization within each response type. A multiple baseline design was used to analyze percentage of matching and nonmatching responses to models across response types. This study, the first to analyze imitative response classes in children with autism, showed that imitation generalized from reinforced training models to nonreinforced probe models within a response type, but it did not generalize across response types. Thus, functional response classes determined by topographical boundaries were exhibited within generalized imitation.
