Letter search does not affect semantic priming in a probe naming task

The normally robust semantic priming effect observed in lexical decision is usually reduced to the point of being absent, when a letter search has to be performed on the prime. It has been argued that semantic activation is thus not an automatic process but rather cognitively controlled and therefore adaptable to task demands. We examined the effects of letter search priming on pronunciation times and found a reliable semantic priming effect, following letter search that was not affected at all relative to a standard condition, where participants silently read the prime. Thus the nature of the prime task did not seem to affect the processing mode employed, semantic access occurred even though attention was focused on surface properties of the prime.     

Egocentric and allocentric visual cues influence the specification of movement distance and direction

The authors investigated whether visuomotor transformations that support the computation of movement distance (i.e., extent) and movement direction rely differentially on integration of egocentric and allocentric visual information. To accomplish that objective, the authors factorially arranged 17 participants' open-loop reaching movements from 2 movement-start locations with mediolateral (ML) and anteroposterior (AP) variants of the induced Roelofs effect (IRE). The 2 movement-start locations in combination with the 2 IRE configurations enabled the authors to examine the impact of illusory movement pertaining to distance (i.e., AP-IRE) and direction (i.e., ML-IRE) information. AP-IRE and ML-IRE configurations across the 2 movement-start locations reliably influenced reaching endpoints in a direction consistent with the perceptual effects of the illusion. These findings suggest that unitary visual information involving interactive egocentric and allocentric visual cues supports the specification of both movement distance and movement direction.     

Domus Ecclesiae: Rethinking a Category of Ante-Pacem Christian Space

Historians of religion, art, and archaeology often invoke theterm domus ecclesiae (oo ) as a technical category to denotea house or building that had been materially adapted for Christianritual during the ante-pacem period. Most employ the term inthe belief that it is genuinely pre-Constantinian, and thatChristians in this period described their cult spaces as renovatedhouses. This essay demonstrates the inaccuracy of both assumptions,and shows that the first attested literary use of the term datesno earlier than 313 CE, when Eusebius of Caesarea (d. 339) usedit in his writings to designate a church building without anyindication of its architectural form or history. Following adiscussion of the term's modern history and an analysis of theancient literary evidence, the essay concludes with a brieflook at the material evidence for domus ecclesiae, which, withone exception (the complex at Dura-Europos), also dates to thepost-Constantinian period.     

How skin and object temperature influence touch sensation

Twenty subjects made magnitude estimations of the apparent heaviness of metallic stimulators of various masses and temperatures (cold, neutral, and warm). The stimulators were placed on the forearm at normal skin temperature (about 33°C), at elevated skin temperature (38°C), and at lowered skin temperature (25°C). Under neutral conditions, we replicated earlier studies: cold objects felt considerably heavier than neutral ones, warm objects somewhat heavier than neutral objects. Warming the skin essentially obliterated the intensifying effect of the warm objects but left unaltered the intensifying effect of the cold objects. Cooling the aim also essentially obliterated the intensifying effect of warm objects. It also diminished, but far from eliminated, the intensifying effect of cold objects. Cold intensification of touch sensation is a large and robust phenomenon and, unlike warm intensification, appears to characterize all body regions.     

Stability of teacher temperament ratings over 6 and 12 months

Six and 12-month stability of teacher ratings of temperament was studied in four samples. For the two samples retested after a 6-month interval, the same teacher provided the original and retest ratings. For the two samples retested after a 12-month interval, different teachers provided the retest ratings than provided the original ratings. Four indices of stability were investigated for each sample: (a) cross-rank stability, (b) within-person stability (c) absolute score stability, and (d) factorial stability. Factorial stability was demonstrated for all samples. For the other three indices of stability, 6-month stability was moderate to high, and significantly higher than the 12-month stability. The general pattern of results is comparable to temperament rating data from parents, with specific coefficients being somewhat higher.     

Effects on WAIS-III performance IQ (PIQ) and full scale IQ (FSIQ) when object assembly is substituted for each standard performance scale subtest

According to the WAIS-III Administration and Scoring Manual, Object Assembly (OA) may be substituted for any spoiled Performance subtest. This assertion has not been evaluated in a clinical sample. The present investigation reports differences that resulted in Performance IQ (PIQ) and Full Scale IQ (FSIQ) when OA replaced each of the Performance subtests. Participants were 47 referrals for neuropsychological assessment (age M = 45.98 years, SD = 9.82; education M = 13.82 years, SD = 2.78). Results indicated that OA may replace any Performance subtest without seriously altering the summary scores. Differences between the standard IQs and OA-based composites were < 2 points for PIQ and < 1 point for FSIQ. More than 90% of the OA-based composites fell within the 90% confidence limits of the corresponding IQ.     

The role of part structure in the perceptual localization of a shape

The process of object localization may be accomplished with respect to a particular reference location, such as the center of gravity, COG (eg Vishwanath and Kowler, 2003 Vision Research 43 1637-1653). Here, we investigated how part structure affects an object's reference location. The reference location was evaluated with a measure of the illusory displacement of an internal target element embedded within a larger object (Morgan et al, 1990 Vision Research 30 1793-1810). To examine whether the reference location is different for shapes with part structure, two shapes were tested: circle (small and large; no part structure) and bell (shape with two parts, one larger than the other). Results were examined with respect to two predictions: either the location of an object is based on its shape as a whole, disregarding part structure (ie a single, overall COG), or the parts are processed separately (different COGs). With the circles, the results showed a systematic illusory displacement of the internal target toward the COG. With the bell, the illusion was significantly weaker than with both circles--even though the main part of the bell had the same size as the small circle, and its horizontal axis had the same extent as the large circle. Moreover, the distance judgments for the bell were consistent with a (weaker) reference point being located at the COG of the larger part, rather than at the COG of the entire bell. These results show that the part structure of a shape plays a role in the representation of its location, and that for complex shapes the perceived location of an embedded element depends more on the parts within which it is embedded, rather than on the whole shape.     

Implicit policies about relations between personality traits and behavioral effectiveness in situational judgment items

This paper develops the concept of implicit trait policy (ITP), which is a variant of the accentuation effect described by Tajfel (1957). ITPs are implicit beliefs about causal relations between personality traits and behavioral effectiveness. Studies reported here tested the hypotheses (a) that personality traits affect ITPs so that agreeable people, for instance, believe the relation between agreeableness and effectiveness is more strongly positive than disagreeable people do and (b) that ITPs can predict behavior that expresses associated personality traits. Two studies with undergraduate research participants supported the first hypothesis for traits of agreeableness and extraversion (the average correlation between traits and associated ITPs was .31 for agreeableness and .37 for extraversion) but not for conscientiousness. A 3rd study with student participants found that individual differences in ITPs for agreeableness predicted agreeable behavior (the average correlation was .33) in simulated work settings. These results suggest that ITPs may be useful for predicting work behavior that expresses personality traits even though ITPs may not be strongly correlated with the personality traits themselves.     

Three steps to open science for qualitative research in psychology

Principles and applications of open science (also referred to as open research or open scholarship) in psychology have emerged in response to growing concerns about the replicability, transparency, reproducibility, and robustness of psychological research alongside global moves to open science in many fields. Our objective in this paper is to inform ways of collectively constructing open science practices and systems that are appropriate to, and get the best out of, the full range of qualitative and mixed-method approaches used in psychology. We achieve this by describing three areas of open research practice (contributorship, pre-registration, and open data) and explore how and why qualitative researchers might consider engaging with these in ways that are compatible with a qualitative research paradigm. We argue it is crucial that open research practices do not (even inadvertently) exclude qualitative research, and that qualitative researchers reflect on how we can meaningfully engage with open science in psychology.
