Attentional scanning and space errors

Using the method of paired comparisons, pairs of simultaneous horizontal or vertical lines, with one line above and one below or one on the left and one on the right of a fixation point, respectively, were presented tachistoscopically for length comparison. Space errors were found to have a pattern similar to that of time errors. The tendency to guess the comparative response from the absolute magnitude of stimuli is proposed as a basis for time and space errors. Manipulation of attentional scanning, which implies a more frequent usage of this guessing strategy for one of the two lines in a pair, was shown to affect space errors.     

Conditioned tilt naming: A modified absolute judgment method is used to measure the oblique effect

Two naive human observers were conditioned to report on the slant of a 3.8-cpd sinusoidal grating viewed monocularly with a light-adapted eye and presented at various orientations extending from ?45 to +135 deg. The procedures used yielded a baseline measure of performance and measures obtained during conditioning, extinction, and reconditioning of the tilt-naming response. Both subjects learned rapidly, achieving a level of performance that permits efficient measurement of meridional differences in perceived orientation Ithe oblique effect) at a large number of angles.     

‘Just leave it blank’ non-religious children and their negotiation of prayer in school

ABSTRACT

This article examines how non-religious children experience acts of collective worship and prayer in primary school settings and analyses how they negotiate religion and their non-religious identities in these events. Drawing on ethnographic fieldwork examining non-religious childhoods and collective worship in three English primary schools, the authors explore how non-religious children demonstrate their agency when confronted with particular boundaries and concepts related to religion and non-religion in school contexts. Attending to the experiences, perspectives, and practices of non-religious children adds to our understanding of the varieties of non-religion, which has to date largely focused on elite, adult populations. Focusing on non-religious children’s experiences of prayer reveals how these children did not experience tensions between praying to God and their non-religious identities and articulated their own interpretations of these practices, deepening understanding of the lived realities of non-religious cultures and identities.     

Awareness growth and dispositional attitudes

Synthese - Richard Bradley and others endorse Reverse Bayesianism as the way to model awareness growth. I raise a problem for Reverse Bayesianism—at least for the general version that Bradley...     

Training sequence effects on emergent conditional discriminations: Replication and extension to selection-based training

We examined the replicability and generality of a previously reported training sequence effect on emergent conditional discriminations in the intraverbal naming task. In Experiment 1, a tact–intraverbal (TI) group learned first to vocally label 6 visual patterns and then to intraverbally relate pairs of verbal labels, whereas an intraverbal–tact (IT) group received the same training in the opposite sequence. Emergent conditional discriminations among pattern stimuli were assessed in match-to-sample (MTS) format. Experiment 2 was identical, except vocal tact and intraverbal training were replaced with selection-based training in which the verbal labels were text stimuli. Compared to the IT sequence, the TI sequence resulted in greater mean accuracy at test (Experiment 1), higher yields (Experiment 2), and shorter reaction times (Experiment 2). Experiment 2 data suggested the TI group's performance might be less dependent on intact intraverbal relations relative to the IT group, but related to participants' reports of visualization during intraverbal training. The results suggest the sequence effect is replicable and occurs in experimental preparations commonly used to study derived stimulus relations. They also provide novel support for the hypothesis that participant behavior during training alters sources of stimulus control available at test.     

The Role of Executive Function and Theory of Mind in Pragmatic Computations

In sentences such as “Some dogs are mammals,” the literal semantic meaning (“Some and possibly all dogs are mammals”) conflicts with the pragmatic meaning (“Not all dogs are mammals,” known as a scalar implicature). Prior work has shown that adults vary widely in the extent to which they adopt the semantic or pragmatic meaning of such utterances, yet the underlying reason for this variation is unknown. Drawing on theoretical models of scalar implicature derivation, we explore the hypothesis that the cognitive abilities of executive function (EF) and theory of mind (ToM) contribute to this observed variation. In Experiment 1, we show that individuals with better ToM are more likely to compute a scalar implicature and adopt the pragmatic meaning of an utterance; however, EF makes no unique contribution to scalar implicature comprehension after accounting for ToM. In Experiment 2, we replicate this finding and assess whether it generalizes to the comprehension of other pragmatic phenomena such as indirect requests (e.g., “It's hot in here” uttered to ask for something to be done) and metaphor (e.g., “to harvest courage”). This is the first evidence that differences in ToM are associated with pragmatic competence in neurotypical adults across distinct pragmatic phenomena.
