The role of general and number-specific order processing in adults’ arithmetic performance

Digit order processing is highly related to individual differences in arithmetic performance. To examine whether serial scanning or associative mechanisms underlie order processing, order tasks (i.e. deciding whether three digits were presented in an order or not) were administered in two experiments. In the first experiment, digits were presented in different directions namely ascending, descending and non-ordered. For each direction, close and far distance sequences were presented. Results revealed reversed distance effects for ordered sequences, but ascending sequences elicited faster performance and stronger reversed distance effects than descending sequences, suggesting that associative mechanisms underlie order processing. In the second experiment, it was examined to which extent the relation between order processing and arithmetic is number-specific by presenting order tasks with digits, letters and months. In all order tasks similar distance effects were observed and similar relations with arithmetic were found, suggesting that both general associative mechanisms and number-specific mechanisms contribute to arithmetic.

Specific conditions for a selective deficit in memory for order in children with dyslexia

Short-term memory (STM) models distinguish between item and order memorization. The present study aims to explore how item and order STM are affected by the nature of the stimuli, the sequential versus simultaneous mode of presentation, the visual versus auditory presentation modality, the possibility of verbal recoding. A total of 20 children with dyslexia were matched one-by-one with 20 typically reading children on sex, age (8–14 years), and grade. Computerized STM tasks were administered while manipulating type (item vs. order), stimuli (letters vs. colors), sequentiality, input and output modality, as well as the presence/absence of articulatory suppression and distractors. General Linear Model analyses were conducted on accuracy scores for item and order STM. Both item and order recall scores were lower for children with dyslexia. Although order STM in the visual input condition turned out to be more impaired than item STM in the dyslexic group, both item and order memory impairments become evident when verbal recoding is prevented through articulatory suppression. Moreover, dyslexic children, unlike typical readers, were not facilitated by the linguistic nature of the stimuli to be remembered. The present findings suggest that the often-reported selective impairment of serial memory in dyslexia is restricted to stimuli that are verbal in nature or can be verbally recoded, whereas both item and order memory impairments become evident when verbal recoding is prevented through articulatory suppression. The presence of distractors is particularly detrimental to STM in the dyslexic group. The sensitivity to distractors, suppression, and stimuli in STM is predictive of reading performance.

Order effects in sequentially judged options due to the direction of comparison

Many real-world judgment tasks present options in sequence. Typically, these judgments are made step-by-step, immediately after considering each option, or end-of-sequence, after all have been seen. We report similar order effects in both procedures, due to direction of comparison. It appears that judges form an impression of each new option by comparing it to those that preceded it. Using that option’s features as a “checklist,” more weight is given to unique ones than to ones shared with previous options. This unidirectional comparison process produces increasing ratings in options with unique positive features, and decreasing ratings when options have unique negative features. By manipulating the barriers to making multiple comparisons, we show that the direction-of-comparison effect is not limited to judgment tasks with sequential presentation. Even simultaneously presented options may show order effects, if they are judged one at a time—in sequence. Possible explanations and implications are discussed.     

Inferring the importance of arguments: Order effects and conversational rules

This paper investigates order effects in one-sided and two-sided communications. While most theorizing attributes both primacy and recency effects to cognitive processes (e.g., attention decrement), we propose that, in addition, communicative aspects play a central role in the emergence of order effects. We postulate that individuals—drawing on conversational norms—hold expectations about the order in which arguments are presented. Depending on these expectations, arguments presented first or last will be highly influential. The results of three studies indicate that recipients hold such expectations, which lead to order effects. Arguments were most influential when they were presented at a position where participants expected the most important arguments. Moreover, these effects were eliminated when the applicability of participants’ expectations was experimentally reduced.     

Practicing the Order of Widows: A New Call for an Old Vocation

This essay argues for a renewed institution of an ancient Christianpractice, the Order of Widows. Drawing on the Roman Catholictradition's recent writings on the elderly, particularly the1998 document from the Pontifical Council for the Laity entitled"The Dignity of Older People and their Mission in the Churchand in the World," I argue that we find within the Roman Catholictradition advocacy for a renewed understanding of the vocationof the elderly within the Church. Building on this, I then tracein the broadest of outlines some elements of what a renewalof the Order of Widows might look like. In doing so, it becomesclear how this new ecclesial practice addresses health issuesof older women (devaluation, marginalization, loss of voice,impoverishment, debilitation, loneliness, isolation, and euthanasia).More importantly, such a practice moves beyond principles todemonstrate a concrete alternative. As such it would providea powerful witness to the very culture the Church seeks to transform.     

Single-probe serial position recall: Evidence of modularity for olfactory,visual, and auditory short-term memory

The present study examined and compared order memory for a list of sequentially presented odours, unfamiliar faces, and pure tones. Employing single-probe serial position recall and following a correction for a response bias, qualitatively different serial position functions were observed across stimuli. Participants demonstrated an ability to perform absolute order memory judgments for odours. Furthermore, odours produced an absence of serial position effects, unfamiliar faces produced both primacy and recency, and pure tones produced recency but not primacy. Such a finding is contrary to the proposal by Ward, Avons, and Melling (2005) that the serial position function is task, rather than modality, dependent. In contrast, the observed functions support a modular conceptualization of short-term memory (e.g., Andrade & Donaldson, 2007; Baddeley & Hitch, 1974), whereby separate modality-specific memorial systems operate. An alternative amodal interpretation is also discussed wherein serial position function disparities are accommodated via differences in the psychological distinctiveness of stimuli (Hay, Smyth, Hitch, & Horton, 2007).     

A model for the time-order error in contrast discrimination

Trials in a temporal two-interval forced-choice discrimination experiment consist of two sequential intervals presenting stimuli that differ from one another as to magnitude along some continuum. The observer must report in which interval the stimulus had a larger magnitude. The standard difference model from signal detection theory analyses poses that order of presentation should not affect the results of the comparison, something known as the balance condition (J.-C. Falmagne, 1985, in Elements of Psychophysical Theory). But empirical data prove otherwise and consistently reveal what Fechner (1860/1966, in Elements of Psychophysics) called time-order errors, whereby the magnitude of the stimulus presented in one of the intervals is systematically underestimated relative to the other. Here we discuss sensory factors (temporary desensitization) and procedural glitches (short interstimulus or intertrial intervals and response bias) that might explain the time-order error, and we derive a formal model indicating how these factors make observed performance vary with presentation order despite a single underlying mechanism. Experimental results are also presented illustrating the conventional failure of the balance condition and testing the hypothesis that time-order errors result from contamination by the factors included in the model.     

Deus or Darwin: Randomness and belief in theories about the origin of life

A simple reminder of the fact that we do not always control life's outcomes reduced people's belief in Darwin's Theory of Evolution. This control-threat resulted in a relative preference for theories of life that thwart randomness, either by stressing the role of a controlling God (Intelligent Design) or by presenting the Theory of Evolution in terms of predictable and orderly processes. Moreover, increased preference for Intelligent Design over evolutionary theory disappeared when the latter was framed in terms of an orderly process with inevitable outcomes. Thus, psychological threat enhances belief in God, but only in the absence of other options that help to create order in the world.
