Two experiments asked whether resistance to change depended on variable-ratio as opposed to variable-interval contingencies of reinforcement and the different response rates they establish. In Experiment 1, pigeons were trained on multiple random-ratio random-interval schedules with equated reinforcer rates. Baseline response rates were disrupted by intercomponent food, extinction, and prefeeding. Resistance to change relative to baseline was greater in the interval component, and the difference was correlated with the extent to which baseline response rates were higher in the ratio component. In Experiment 2, pigeons were trained on multiple variable-ratio variable-interval schedules in one half of each session and on concurrent chains in the other half in which the terminal links corresponded to the multiple-schedule components. The schedules were varied over six conditions, including two with equated reinforcer rates. In concurrent chains, preference strongly overmatched the ratio of obtained reinforcer rates. In multiple schedules, relative resistance to response-independent food during intercomponent intervals, extinction, and intercomponent food plus extinction depended on the ratio of obtained reinforcer rates but was less sensitive than was preference. When reinforcer rates were similar, both preference and relative resistance were greater for the variable-interval schedule, and the differences were correlated with the extent to which baseline response rates were higher on the variable-ratio schedule, confirming the results of Experiment 1. These results demonstrate that resistance to change and preference depend in part on response rate as well as obtained reinforcer rate, and challenge the independence of resistance to change and preference with respect to response rate proposed by behavioral momentum theory.
<p>Play is a universal and innate disposition that is believed to be one of the most significant components to holistic wellbeing and development during the foundational years of childhood. Research and literature examining the topic of play in early childhood suggests that while unstructured and child directed play is valued, its existence is under threat. Instead, it is being replaced by structured, educational, and adult directed activities which aim to accelerate young children’s learning. Due to these conflicting paradigms, and a lack of research exploring parental values in this area, this quantitative study examined parental perceptions towards structured and unstructured play for children under the age of three years. In order to investigate this topic, 255 New Zealand parents, with children not in full-time childcare and under the age of three years, participated in an anonymous online survey. The survey was designed specifically for this study due to a lack of pre-existing measures. The main finding was that parental perception influenced the way in which infants and toddlers spent their time. The majority of parents perceived unstructured play to best support early development and, consequently, offered children a large amount of daily time to become involved in freely chosen unstructured play. The study also identified that: the more weekly activities a child engaged in, the higher structured play was valued by parents; older parents did not value structured play as highly as younger parents; parents with a tertiary level qualification valued unstructured play more than those parents with a school qualification or less; screen time was perceived to be more appropriate the older the child. These findings were discussed in relation to the implications they raise for the role of the parent, early childhood education, parent education, and child development and wellbeing.</p>
