Paradigm shift in religious education: a reply to Jackson,or why religious education goes to war

This article provides a defence of my theoretical analysis of paradigm shift in contemporary religious education, particularly in light of Robert Jackson’s (2015) article published in this journal: ‘Misrepresenting religious education’s past and present in looking forward: Gearon using Kuhn’s concepts of paradigm, paradigm shift and incommensurability’. The core of Jackson’s concerns is my adaptation of Kuhn’s concepts of paradigm, paradigm shift and incommensurability to religious education. Defending in turn my use of these concepts – of paradigm, paradigm shift and incommensurability – I conclude that Jackson’s critique is in and of itself an apt demonstration of the position he seeks to attack. Drawing wider parallels with the methodological ‘paradigm wars’ in the social sciences I argue that the paradigms are why religious education too goes to ‘war’.     

An item/order trade‐off explanation of word length and generation effects

The item‐order hypothesis suggests that under certain conditions increased item processing can lead to deficits in order processing, and that this produces a dissociation in performance between item and order tasks. The generation effect is one such example. The word length effect is seen as another instance where this trade‐off might be observed. The following experiments compare word length and generation effects under serial recall and single item recognition conditions. Short words are better recalled than long words on the serial recall task but long words were better recognised than short words. The results are consistent with the item‐order approach and support a novel explanation for the word length effect.     

Stressing the Flesh: In Defense of Strong Embodied Cognition

In a recent paper, Andy Clark (2008) has argued that the literature on embodied cognition reveals a tension between two prominent strands within this movement. On the one hand, there are those who endorse what Clark refers to as body‐centrism, a view which emphasizes the special contribution made by the body to a creature’s mental life. Among other things, body centrism implies that significant differences in embodiment translate into significant differences in cognition and consciousness. On the other hand, there are those who endorse what Clark calls extended functionalism, a view which sees the mind as the joint product of the computational resources presented by (i) intracranial processing, (ii) bodily input, and (iii) environmental scaffolding. As such, extended functionalism allows for the possibility that any contribution of the body to cognition and consciousness can be compensated for by the other two contributing factors. While Clark’s sympathies lie with the latter approach, we argue in favour of the former. In particular, we focus on consciousness and argue that the unique contribution the body makes to a creature’s manifold of phenomenal experience cannot be compensated for, in the manner, and on the scale, that Clark envisages.     

An investigation of spatial representation of pitch in individuals with congenital amusia

Spatial representation of pitch plays a central role in auditory processing. However, it is unknown whether impaired auditory processing is associated with impaired pitch–space mapping. Experiment 1 examined spatial representation of pitch in individuals with congenital amusia using a stimulus–response compatibility (SRC) task. For amusic and non-amusic participants, pitch classification was faster and more accurate when correct responses involved a physical action that was spatially congruent with the pitch height of the stimulus than when it was incongruent. However, this spatial representation of pitch was not as stable in amusic individuals, revealed by slower response times when compared with control individuals. One explanation is that the SRC effect in amusics reflects a linguistic association, requiring additional time to link pitch height and spatial location. To test this possibility, Experiment 2 employed a colour-classification task. Participants judged colour while ignoring a concurrent pitch by pressing one of two response keys positioned vertically to be congruent or incongruent with the pitch. The association between pitch and space was found in both groups, with comparable response times in the two groups, suggesting that amusic individuals are only slower to respond to tasks involving explicit judgments of pitch.     

Facial expressions of singers influence perceived pitch relations

In four experiments, we examined whether facial expressions used while singing carry musical information that can be “read” by viewers. In Experiment 1, participants saw silent video recordings of sung melodic intervals and judged the size of the interval they imagined the performers to be singing. Participants discriminated interval sizes on the basis of facial expression and discriminated large from small intervals when only head movements were visible. Experiments 2 and 3 confirmed that facial expressions influenced judgments even when the auditory signal was available. When matched with the facial expressions used to perform a large interval, audio recordings of sung intervals were judged as being larger than when matched with the facial expressions used to perform a small interval. The effect was not diminished when a secondary task was introduced, suggesting that audio-visual integration is not dependent on attention. Experiment 4 confirmed that the secondary task reduced participants’ ability to make judgments that require conscious attention. The results provide the first evidence that facial expressions influence perceived pitch relations.     

Dynamical agents: Consciousness, causation, and two specters of epiphenomenalism

The aim of this paper is to defend the causal efficacy of consciousness against two specters of epiphenomenalism. We argue that these challenges are best met, on the one hand, by rejecting all forms of consciousness-body dualism, and on the other, by adopting a dynamical systems approach to understanding the causal efficacy of conscious experience. We argue that this non-reductive identity theory provides the theoretical resources for reconciling the reality and efficacy of consciousness with the neurophysiology of the brain and body.

Periodic Reinforcement and Second-Order Schedules

In two experiments, rats were trained initially on a recycling conjunctive schedule in which a food pellet was delivered after 30 s provided at least one response had occurred; otherwise the next cycle began immediately. This produced low rate responding characterized by either a pause-respond-pause pattern or else a pause-respond pattern. The schedule then was changed so that half of the intervals ended with the presentation of a brief stimulus instead of food. Patterning after food was little affected, whereas patterning after the brief stimulus varied across rats. Generally, a short pause after the brief stimulus was followed by an initial increase in responding that led to either a fairly constant rate, or else to a decrease in rate throughout the interval. In later conditions, when the incidence of response-food and response- stimulus contiguity were manipulated separately, only the former increased response rate; this was so even when the brief stimulus was paired with food in some conditions. Rate increases were accompanied by changes in patterning across all intervals. These results do not support a simple conditioned reinforcement interpretation of the control acquired by a brief stimulus on a second-order schedule with fixed-interval components. Rather, they suggest that a number of interrelated variables combine to maintain responding. These variables include response-reinforcer contiguity, the temporal location of the response dependency, and the contingency between the brief stimulus and the reinforcer.

     

The subjective size of melodic intervals over a two-octave range

Musically trained and untrained participants provided magnitude estimates of the size of melodic intervals. Each interval was formed by a sequence of two pitches that differed by between 50 cents (one half of a semitone) and 2,400 cents (two octaves) and was presented in a high or a low pitch register and in an ascending or a descending direction. Estimates were larger for intervals in the high pitch register than for those in the low pitch register and for descending intervals than for ascending intervals. Ascending intervals were perceived as larger than descending intervals when presented in a high pitch register, but descending intervals were perceived as larger than ascending intervals when presented in a low pitch register. For intervals up to an octave in size, differentiation of intervals was greater for trained listeners than for untrained listeners. We discuss the implications for psychophysical pitch scales and models of music perception.
