Timing in trace conditioning of the nictitating membrane response of the rabbit (Oryctolagus cuniculus): scalar, nonscalar, and adaptive features

Using interstimulus intervals (ISIs) of 125, 250, and 500 msec in trace conditioning of the rabbit nictitating membrane response, the offset times and durations of conditioned responses (CRs) were collected along with onset and peak latencies. All measures were proportional to the ISI, but only onset and peak latencies conformed to the criterion for scalar timing. Regarding the CR's possible protective overlap of the unconditioned stimulus (US), CR duration increased with ISI, while the peak's alignment with the US declined. Implications for models of timing and CR adaptiveness are discussed.     

Developing student social skills using restorative practices: a new framework called H.E.A.R.T

Students attending schools today not only learn about formal academic subjects, they also learn social and emotional skills. Whole-school restorative practices (RP) is an approach which can be used to address student misbehaviour when it occurs, and as a holistic method to increase social and emotional learning in students. The aim of this study was to explore the impact of RP on student behaviour from the perspectives of students and teachers. Six schools participated in interviews and focus groups. Students and teachers were asked about the use of RP and the impact on behaviour. Students and teachers identified five main themes: greater harmony, increased empathy towards others, awareness of one’s own behaviour and being accountable for that, increased respect, and reflective thinking. These aspects increase students’ social skills. This paper discusses a new framework which describes the positive impact of RP on student behaviour and thinking. The findings have broad implications for school communities and highlight the need to move towards more relational behaviour management approaches.     

REVITALIZATION MOVEMENTS AND THE HOPE OF PEACE

Abstract. Anthropological analysis of religion, following Bronislaw Mahowski, is founded in empirical observational data gained at least in part by participant observation. Malinowski described religion as a "sociological charter" which is a "retrospective moral pattern of behavior," constructed as a myth after the fact of behavior. Anthony F. C. Wallace's revitalization model provides the mechanism through which the Malinowskian charter is developed. Jack Wilson's Ghost Dance religion is briefly described as an example of a revitalization movement, and it is suggested that both contemporary peace movements and militant Christian movements are revitalization movements.     

Classical conditioning of the rabbit's nictitating membrane response under fixed and mixed CS-US intervals

The rabbit's nictitating membrane response was classically conditioned to a tone CS, followed by an electric shock US, at two randomly alternating CS-US interstimulus intervals (ISIs). Different groups were exposed to different proportions of 200- and 700-msec ISIs. The study revealed: (a) CR percentage was a direct function of the proportion of 200-msec ISIs; (b) trials to the first test-trial CR were an inverse function of the proportion of 200-msec ISIs; (c) CR onset latencies decreased over training; (d) CR peak latencies coincided with the temporal loci of the US; and (e) groups exposed to both ISIs acquired double-peaked CRs. Moreover, the amplitudes of nictitating membrane responses in the present experiment paralleled certain quantitative aspects of the free operant key peck response rates of pigeons trained under two mixed inter-reinforcement intervals. The results were discussed with respect to the micromolar response shaping and macromolecular CS-trace accounts of classical conditioning.     

Commentary on Pareto‐Optimality as a Rationale for Adverse Impact Reduction: What would organizations do?

This paper offers an organizational perspective about the Pareto‐optimality of trade‐offs between selection quality and adverse impact reduction described by De Corte, Lievens and Sackett. Based on considerations of culture and human resource strategy, the need to understand the impact of any trade‐off, and a desire to compare this approach to alternatives, it is concluded that organizations may be strategically disinclined to implement such trade‐offs and, if interested, organizations would desire more information than is available from the accumulated research in this domain. In particular, validity differences between Pareto‐optimal composites are not likely to be good indicators of selection quality differences and the comparative effectiveness of alternative approaches is not clear.     

Apparatus exposure produces profound declines in conditioned nictitating-membrane responses to discrete conditioned stimuli by the rabbit (Oryctolagus cuniculus)

The present experiments demonstrated that in the rabbit (Oryctolagus cuniculus) nictitacing-membrane (NM) preparation, exposure to the experimental apparatus produces profound declines in conditioned responding to a discrete conditioned stimulus (CS; Experiments 1, 2A, and 3). Moreover, this decremental effect is at most attenuated in only a minor way when the unconditioned stimulus (US) is presented during exposure to the apparatus (Experiment 2B). Controls for retention loss (Experiments 1 and 3) and for handling and placement in a different context (Experiment 3) did not produce significant declines in responding. These findings challenge theories of extinction that rely primarily on context-US associations but are more consistent with theories that assume context-CS-US associations.     

Overexpectation: response loss during sustained stimulus compounding in the rabbit nictitating membrane preparation

Rabbits were given reinforced training of the nictitating membrane (NM) response using separate conditioned stimuli (CSs), which were a tone, light, and/or tactile vibration. Then, two CSs were compounded and given further pairings with the unconditioned stimulus (US). Evidence of both overexpectation and summation effects appeared. That is, responding to the individual CSs declined despite their continued pairing with the US on compound trials (overexpectation), and responding on the compound trials was greater than responding to the individual CSs (summation). The response loss appeared regardless of the testing regime, that is, whether the test presentations of the individual CSs were themselves reinforced (Experiment 2), not reinforced (Experiment 1), or deferred until the end of compound training (Experiment 2). The results are discussed with respect to the roles of excitatory versus inhibitory processes, elemental versus configural processes, and the possible roles of cerebellar and hippocampal pathways.

Transfer and Counterconditioning of Conditional Control in the Rabbit Nictitating Membrane Response

Two experiments using the rabbit nictitating membrane response investigated whether training in one conditional discrimination (A X+, B X-), enabled the feature cues (A and B) to modulate responding to another CS (Y) trained as a target stimulus in a second conditional discrimination (C Y+, D Y-). There was near-complete transfer of the feature cue's conditional control, indicating that the feature cue's ability to modulate responding is not based on an association specific to the training target. Experiment 2 also revealed that the role of a stimulus to act as a conditional cue is affected by its ability to act as a simple conditioned excitor or inhibitor. Following initial acquisition of two conditional discriminations, two feature cues were reinforced in a pattern consistent with the initial conditional discrimination (A +, B-), whereas the other two feature cues were reinforced in the reverse pattern to that of the original conditional discrimination (C-, D +). Subsequent tests revealed that the reversed training of the feature cues interfered with the original conditional discriminations. The results are consistent with theories that the feature cue gains an association with a representation of the emotional attributes of the US, which acts to modulate responding to the target stimulus through a diffuse change in motivational level. However, hierarchical theories of conditional discriminations that assume a lack of CS-specificity may also be able to explain the findings.
