Effects of Grammatical Categories on Letter Detection in Continuous Text

The present study focuses on the interplay between the linguistic principles and the psycholinguistic processes involved in reading. Results from 56 participants on a letter detection task reveal that readers do not process all function words in the same manner. Omission rates were highest for function words occupying the head of maximal projections such as complementizers and determiners. Prepositions were shown to occupy an intermediary position between content and function words, with omission rates varying depending on their semantic load. Together these results appear to bolster and offer a finer grained picture of the role of function words within the framework of both the Guidance Organization (Greenberg et al. in Psychon Bull Rev 11(3):428–433, 2004) and Attentional Disengagement (Roy-Charland et al. in Percept Psychophys 69(3):324–337, 2007) reading models. The results of the present study are discussed using an X-bar theory approach with the goal of refining the structural account of letter detection errors.     

Project DyAdd: Visual attention in adult dyslexia and ADHD

In this study of the project DyAdd, three aspects of visual attention were investigated in adults (18–55 years) with dyslexia (n = 35) or attention deficit/hyperactivity disorder (ADHD, n = 22), and in healthy controls (n = 35). Temporal characteristics of visual attention were assessed with Attentional Blink (AB), capacity of visual attention with Multiple Object Tracking (MOT), and spatial aspects of visual attention with Useful Field of View (UFOV) task. Results showed that adults with dyslexia had difficulties performing the AB and UFOV tasks, which were explained by an impaired ability to process dual targets, longer AB recovery time, and deficits in processing rapidly changing visual displays. The ADHD group did not have difficulties in any of the tasks. Further, performance in the visual attention tasks predicted variation in measures of phonological processing and reading when all of the participants were considered together. Thus, difficulties in tasks of visual attention were related to dyslexia and variation of visual attention had a role in the reading ability of the general population.     

Incomplete understanding of complex numbers Girolamo Cardano: a case study in the acquisition of mathematical concepts

In this paper, I present the case of the discovery of complex numbers by Girolamo Cardano. Cardano acquires the concepts of (specific) complex numbers, complex addition, and complex multiplication. His understanding of these concepts is incomplete. I show that his acquisition of these concepts cannot be explained on the basis of Christopher Peacocke’s Conceptual Role Theory of concept possession. I argue that Strong Conceptual Role Theories that are committed to specifying a set of transitions that is both necessary and sufficient for possession of mathematical concepts will always face counterexamples of the kind illustrated by Cardano. I close by suggesting that we should rely more heavily on resources of Anti-Individualism as a framework for understanding the acquisition and possession of concepts of abstract subject matters.     

The effect of visual complexity and word frequency on eye movements during Chinese reading

Eye movements of native Chinese readers were monitored when they read sentences containing single-character target words orthogonally manipulated for frequency and visual complexity (number of strokes). Both factors yielded strong main effects on skipping probability but no interaction, with readers skipping visually simple and high frequency words more often. However, an interaction between frequency and complexity was observed on the fixation times on the target words with longer fixations for the low frequency, visually complex words. The results demonstrate that visual complexity and frequency have independent influences on saccadic targeting behaviour during Chinese reading but jointly influence fixation durations and that these two factors differently impact fixation durations and saccade targeting during reading.     

Updating and feature overwriting in short-term memory for timbre

Previous research has demonstrated a potent, stimulus-specific form of interference in short-term auditory memory. This effect has been interpreted in terms of interitem confusion and grouping, but the present experiments suggested that interference might be a feature-specific phenomenon. Participants compared standard and comparison tones over a 10-sec interval and were required to determine whether they differed in timbre. A single interfering distractor tone was presented either 50 msec or 8 sec after the offset of the standard (Experiment 1) or 2 sec prior to its onset (Experiment 2). The distractor varied in the number of features it shared with the standard and comparison, and this proved critical, since performance on the task was greatly impaired when the distractor either consisted of novel, unshared features (Experiment 1) or contained the distinguishing feature of the comparison tone (Experiments 1 and 2). These findings were incompatible with earlier accounts of forgetting but were fully explicable by the recent timbre memory model, which associates interference in short-term auditory memory with an "updating" process and feature overwriting. These results suggest similarities with the mechanisms that underlie forgetting in verbal short-term memory.     

The perceptual origins of the abstract same/different concept in human infants

Very few experiments have studied the two item same/different relation in young human infants. This contrasts with an extensive animal literature. We tested young infants with two novel tasks designed specifically to provide convergent comparative measures. Each infant completed both tasks allowing an assessment of their understanding of the abstract concept rather than task-specific abilities. In a looking time task with photographic stimuli, we found that 8-month-olds are sensitive to the relation but 4-month-olds are not. The second task used an anticipatory eye movement paradigm with simple geometric stimuli. On each trial, two colored shapes appear and moved upwards behind an occluder. They reappeared on either the upper left or right depending on the relation between them. Infants at both ages learned and generalized the dependency but only for the different relation. These results show that human infants can learn the same/different concept but that, in strong continuity with animal results, their abilities are firmly grounded in perception.     

Beyond individual justice facets: How (Mis)alignment between justice climates affects customer satisfaction through frontline customer extra-role service behavior

ABSTRACT

This study examines the combined effect of organizational justice facets on store-level customer extra-role service behavior, and subsequently on customer satisfaction. Hypotheses were tested on a sample of 1,951 employees in 121 business units from four countries, and on 55,731 customers of an international retailer. The results of polynomial regression and response surface analysis revealed that unit customer service performance and customer satisfaction are higher when justice facets are aligned at high levels, compared to when they are aligned at low levels. Moreover, we found evidence that the consequences of misalignment between justice facets are asymmetrical. Unit outcomes were higher when distributive justice (DJ) and procedural justice (PJ) climates were both higher than the interpersonal justice climate, compared to when the inverse was true. Conversely, unit outcomes increased when informational justice (INF-J) climate was higher than DJ and PJ climates, compared to when DJ and PJ climates were higher than INF-J climates. The observed effects of misalignment between justice facets were non-linear, as complex curvilinear relationships were moderator-dependent. Customer satisfaction was higher in stores with higher team customer service behavior, and team service behavior was found to be a significant conduit by which justice facets (mis)alignment influence customer satisfaction.     

Christology in the Meeting Between Science and Religion. A Tribute to Ian Barbour

While Ian Barbour's methodological contributions to science and religion and his use of process metaphysics are often noted, it is also important to consider his own theology of nature as a significant contribution to Christian theology. This article calls attention to both his reformulation of Christology and to the way Christology functions in his understanding of divine action. It goes on to suggest that Christology is important for three aspects of continuing work in science and theology     

Prediction of dietary adherence in cholesterol reduction: Relative contribution of personality variables and health attitudes

Abstract

The purpose of this study was to identify personality and health attitude variables that might predict adherence to a cholesterol-reducing diet.

After taking a battery of psychological inventories, 66 subjects entered a 26 week diet program. Adherence indices included attendance rate at scheduled appointments, changes in diet, and changes in serum cholesterol levels.

Of the 55 subjects with complete data, 7 dropped out, 7 attended inconsistently, and 41 completed the program. Drop-outs scored significantly lower on the Health Belief measures of seriousness, susceptibility, and benefits. Improvement in serum cholesterol was positively correlated with the Health Belief Benefits Scale and negatively correlated with the Health Locus of Control chance scale. Dietary reduction in saturated fat was positively associated with the Health Belief Seriousness and Benefits Scales.

Health attitudes and beliefs were better predictors of adherence than personality trait measures.
