Activation of lexical and semantic representations without intention along GPC-sublexical and orthographic-lexical reading pathways in a Stroop paradigm.

Dual route models of reading suggest there are 2 pathways for reading words: an orthographic-lexical pathway, used to read familiar regular words and exception words, and a grapheme-to-phoneme-conversion-(GPC)-sublexical pathway, used to read unfamiliar regular words, pseudohomophones (PHs), and nonwords. It is unclear, however, whether PHs activate lexical and semantic representations without intention in the GPC-sublexical pathway to the same extent as words along the orthographic-lexical pathway. The present study explored this by introducing a novel condition, color pseudohomophone associates (CPHAs; e.g., "skigh"), in 3 experiments using the Stroop paradigm. Experiment 1 examined 4 types of stimuli: color words (CWs), color word associates (CWAs), color PHs (CPHs), and color PH associates (CPHAs), in a mixed list context. Significant Stroop effects were found for all 4 types of stimuli. To ensure the robustness of this effect, Experiment 2 was conducted using pure list contexts whereby participants received only word stimuli (e.g., CWs, CWAs) or only PH stimuli (e.g., CPHs, CPHAs). The results replicated those of Experiment 1, suggesting that CPHAs activate lexical and semantic representations without intention in the GPC-sublexical pathway. Experiment 3 added 2 novel conditions: color exception word associates (which can only be pronounced correctly using the orthographic-lexical pathway) to compare the effects obtained with color exception PH associates (which rely on the GPC-sublexical pathway for correct pronunciation). Stroop effects of similar magnitude were found for both types of stimuli, suggesting lexical and semantic representations are accessed without intention in either reading pathway to a similar degree. Implications for models of reading are discussed.

Contextual influences on the sequential congruency effect

The sequential congruency effect (SCE) refers to the reduction in the size of the congruency effect following incongruent, relative to congruent, trials. Prior evidence indicated that the SCE does not generalize across tasks or different conflict-producing feature dimensions. We present results from a Stroop task showing that when the local list context is such that all colors and words appear in the same proportion of congruent trials, the SCE is present, but when those same items vary in the proportions congruent, the SCE is absent. We suggest that if stimuli are sufficiently consistent in the informativeness of their dimensions for the responses, individuals will attempt to track such information and weight the dimensions accordingly. In this way, the SCE reflects sequential adjustments to the weights given to individual stimulus dimensions in an attempt to track this information.

Reducing False Memories via Context Reinstatement: The Roles of Encoding and Retrieval Contexts

Reinstatement of encoding strategies during recall was investigated in 3 experiments using the Deese-Roediger-McDermott paradigm (Deese, 1959; Roediger & McDermott, 1995). Participants studied lists using either elaborative or rote rehearsal encoding strategies. At test, participants either reinstated their original encoding strategies or used opposing strategies to recall. In Experiment 1, participants provided "think aloud" verbal reports during study and test, and elaborative encoding led to higher levels of correct recall, more instances of verbalizations of critical items, and lower false recall compared with rote encoding. Experiment 2 replicated the results of Experiment 1 without verbal reports. In Experiment 3, false recall was lower only after elaborative encoding and reinstatement of that encoding context. Results support the role of distinctiveness in false recall, which is sensitive to changes in list context and retrieval context after elaborative encoding.

Die Herausbildung des biblischen Kanons im antiken Judentum und im frühen Christentum

Abstract Starting with the observation that the canon of the Bible differs among the Christian denominations (Lutheran, Reformed, Roman Catholic), and that definitive decisions on the canon were not made before the 16th century, the author gives a brief account of the process of the development of both the Jewish and the bipartite Christian canon. Due to more recent textual discoveries, earlier views of the making of the Jewish or the Christian canon have undergone significant changes. For the Jewish canon, the discovery of the Dead Sea Scrolls (Qumran texts) provided the opportunity to study the making of the canon from manuscript evidence, and to alter the overall view from the pattern of a three stage canonization to the pattern of a “canonical process”, leading to the Hebrew canon and, later and in Christian circles, to the canon of the Septuagint. This pattern is also useful for studying the making of the bipartite Christian canon or the New Testament canon. Here, the author focuses on the challenge provided by Marcion’s “canon”, the early beginning of the canonical process and its late closure, and the various factors in the process, which can be studied by including the manuscript evidence and taking into account the character of several apocryphal texts and the context and intention of the various lists of canonical texts. The biblical canon as presupposed throughout the Middle Ages is the result of a complicated and variegated canonical process. But in spite of the problems of the criteria and factors involved, the biblical canon is theologically valuable and “well-chosen”.

Past tense route priming

The present research examined whether lexical (whole word) or more rule-based (morphological constituent) processes can be locally biased by experimental list context in past tense verb inflection. In Experiment 1, younger and older adults completed a past tense inflection task in which list context was manipulated across blocks containing regular past tense verbs (e.g. REACH-REACHED) or irregular past tense verbs (TEACH-TAUGHT). Critical targets, consisting of half regular and half irregular verbs, were embedded within blocks and participants’ inflection response latency and accuracy were assessed. The results yielded a cross-over interaction in response latencies for both young and older adults. In the regular context there was a robust regularity effect: regular target verbs were conjugated faster than irregular target verbs. In contrast, in the irregular context, irregular target verbs were conjugated faster than regular target verbs. Experiment 2 used the same targets but in the context of either standard nonwords or nonwords ending in “-ED” to test the possibility of a phonological basis for the effect. The effect of context was eliminated. The results support the notion that distinct processes in past tense verb production can be locally biased by list context and, as shown in Experiment 2, this route priming effect was not due to phonological priming.

Event-related brain potentials of masked repetition and semantic priming while listening to sentences

We combined for the first time electrophysiological measures and masked priming technique in sentential context, by setting up a cross-modal masked priming paradigm involving the auditory presentation of sentences. ERPs were time-locked to an auditorily presented word that was preceded by a repeated, related or unrelated pattern masked prime. We registered a two-way N400-difference between unrelated and related/repeated primes, followed by a late positive component (LPC) for repetition priming. Related primes appear to facilitate the lexical-semantic processing of the target to the same extent repeated primes do (equally attenuated N400). Repetition priming exerts additional demands (LPC), possibly related to enhanced recollection or to the construction of a discourse representation. This evidences that the sentential context interacts with masked priming in two vital ways, differing from word list contexts, and paves the way for future studies on the mechanisms of lexical/semantic processes beyond the word level.

How to say “no” to a nonword: A leaky competing accumulator model of lexical decision.

We describe a leaky competing accumulator (LCA) model of the lexical decision task that can be used as a response/decision module for any computational model of word recognition. The LCA model uses evidence for a word, operationalized as some measure of lexical activity, as input to the YES decision node. Input to the NO decision node is simply a constant value minus evidence for a word. In this way, evidence for a nonword is a function of time from stimulus onset (as in standard deadline models) modulated by lexical activity via the competitive dynamics of the LCA. We propose a simple mechanism for determining the value of this constant online during the first trials of a lexical decision experiment, such that the model can rapidly optimize speed and accuracy in discriminating words from nonwords. Further optimization is achieved via trial-by-trial adjustments in response criteria as a function of task demands and list context. We show that the LCA model can simulate mean response times and response distributions for correct and incorrect YES and NO decisions for a number of benchmark experiments that have been shown to be fatal for deadline models of lexical decision. Finally, using lexical activity calculated by a computational model of word recognition as input to the LCA decision module, we provide the first item-level simulation of both word and nonword responses in a large-scale database.

There goes the neighbourhood: Contextual control over the breadth of lexical activation when reading aloud

There are currently two computational accounts of how the time to read pseudohomophones (like BRANE) and their nonword controls (like FRANE) varies with changes in context. In Reynolds and Besner's (2005) account, readers vary the breadth of lexical activation in response to changes in context. A competing account proposed by Kwantes and Marmurek (2007) and independently by Perry, Ziegler, and Zorzi (2007) has readers varying their response criterion in response to changes in context. The present work adjudicates between these two accounts by examining how the effect of neighbourhood density changes as a function of list context when reading pseudohomophones aloud. The results of an experiment and simulations from a leading computational model support the lexical breadth account, but are inconsistent with the response criterion account.

List context manipulation reveals orthographic deficits in Italian readers with developmental dyslexia

We tested the influence of list context on word frequency and length effects on the reading aloud of Italian developmental dyslexics and skilled peers. The stimuli were presented either in mixed blocks (alternating words and nonwords) or in pure blocks. The analyses based on the rate-and-amount model (Faust et al., 1999) indicated that group differences in reaction times between dyslexic and skilled readers (a) were well accounted for in terms of global components and (b) were modulated by context in the case of words but not in the case of nonwords. ANOVAs on z-transformed reaction time data further indicated the influence of stimulus length. Importantly, the frequency effect interacted with context: Controls showed a list context effect for high- and low-frequency words, while dyslexics showed a list context effect only for high-frequency words. The effect of length on reading times remained unaffected by context manipulation. It is proposed that this pattern of results may be accounted for by hypothesizing two separate deficits: An early graphemic impairment affecting performance independently of context and a later inefficiency in activating entries in the orthographic lexicon as a function of context demands.

The effect of generation on long-term repetition priming in auditory and visual perceptual identification

Perceptual implicit memory is typically most robust when the perceptual processing at encoding matches the perceptual processing required during retrieval. A consistent exception is the robust priming that semantic generation produces on the perceptual identification test (Masson & MacLeod, 2002), a finding which has been attributed to either (1) conceptual influences in this nominally perceptual task, or (2) covert orthographic processing during generative encoding. The present experiments assess these possibilities using both auditory and visual perceptual identification, tests in which participants identify auditory words in noise or rapidly-presented visual words. During the encoding phase of the experiments, participants generated some words and perceived others in an intermixed study list. The perceptual control condition was visual (reading) or auditory (hearing), and varied across participants. The reading and hearing conditions exhibited the expected modality–specificity, producing robust intra-modal priming and non-significant cross-modal priming. Priming in the generate condition depended on the perceptual control condition. With a read control condition, semantic generation produced robust visual priming but no auditory priming. With a hear control condition, the results were reversed: semantic generation produced robust auditory priming but not visual priming. This set of results is not consistent with a straightforward application of either the conceptual-influence or covert-orthography account, and implies that the nature of encoding in the generate condition is influenced by the broader list context.

The sentence-composition effect: Processing of complex sentences depends on the configuration of common noun phrases versus unusual noun phrases.

In 2 experiments, the authors used an eye tracking while reading methodology to examine how different configurations of common noun phrases versus unusual noun phrases (NPs) influenced the difference in processing difficulty between sentences containing object- and subject-extracted relative clauses. Results showed that processing difficulty was reduced when the head NP was unusual relative to the embedded NP, as manipulated by lexical frequency. When both NPs were common or both were unusual, results showed strong effects of both commonness and sentence structure, but no interaction. In contrast, when 1 NP was common and the other was unusual, results showed the critical interaction. These results provide evidence for a sentence-composition effect analogous to the list-composition effect that has been well documented in memory research, in which the pattern of recall for common versus unusual items is different, depending on whether items are studied in a pure or mixed list context. This work represents an important step in integrating the list-memory and sentence-processing literatures and provides additional support for the usefulness of studying complex sentence processing from the perspective of memory-based models.

The revelation of the negative side of a mental number line depends on list context: Evidence from a sign priming paradigm

Two parity judgement experiments examined how the activation of spatial-numerical associations of a single, centrally presented digit, reflected by the Spatial-Numerical Association Response Codes (SNARC) effect, is modulated by a preceding + (plus) or − (minus) prime. The centrally presented prime prior to a digit presentation presumably triggers its positive or negative attributes. When the plus- and minus-primed trials were blocked, the left-small/right-large SNARC effects occurred regardless of prime type. When the plus- and minus-primed trials were randomly intermixed, this left-small/right-large SNARC effect occurred for plus-primed digits, but was reversed for minus-primed digits. The implications of this finding for context-dependent SNARC effects are discussed.

List context effects in reading Italian words and nonwords: Can the word frequency effect be eliminated?

It has been suggested that when words and nonwords are presented mixed in the same blocks in transparent scripts the word frequency effect can be eliminated. This is either because in reading mixed blocks the lexical route is deemphasised in favour of the nonlexical route (route deemphasis) or because a homogenisation of reaction times occurs for words and nonwords by adjustment of a time criterion for articulation (time criterion). In five experiments using different list manipulations and experimental designs, we assessed the effects of frequency and length in reading aloud words and nonwords in the Italian transparent orthography. The effect of word frequency remained constant irrespective of context manipulation and nonword characteristics. As reading nonwords may be easier in Italian than in English, control over reading processing may be unnecessary for Italian readers. The results are discussed with respect to current computational models of reading.

The Practice, Purpose, and Perils of List-Making

In spring 2009 issue of International Journal, John Kirton published his of important books on Canadian foreign He framed his as a response to what he believes to be one remaining unanswered question about field: Is Canadian foreign policy really a self-contained field with an intellectually coherent, progressive research tradition, defined by seminal books of creative inspiration and continuing relevance at its core?1 Although Kirton suggests that good reasons to doubt that (554), exercise of producing such a convinces him that there is, at long last, a single field of Canadian foreign policy, reflective of rich diversity that subject itself contains (564). In putting forward his list, Kirton invites others to offer their own suggestions and amendments, presenting as the beginning of a debate about what field is, on what its best books are(556), rather than as definitive statement ofthe best books in field. Despite this, Kirton does go on to argue that virtuaUy all scholars should accept of his selections as clear choices or credible candidates, and where readers' personal favourites have been omitted, these scholars should be able to mount a considered case to explain why personal favourite that has been omitted is better than one or more of Kirton's own personal favourites (555).In responding to Kirton's article, we talcing up invitation to interrogate what constitutes academic field of Canadian foreign policy. In doing so, is neither our intent nor our desire to produce an alternative of books in response to Kirton's top 10. Rather, we want to raise questions about entire enterprise of production, whether those lists of important books, of books, or of scholars.2 The act of defining a field based on what its best books are is an exercise that is inherently political, and not only for reason that Kirton identifies - that it is unlikely that aU scholars currently teaching and researching in [Canadian foreign policy] wul agree with every book on list (555). Whue we may (and wul) query selection of books that Kirton has included on his list, is not choice of individual books that causes us greatest consternation. Rather, our concern is with fact of producing such a in first instance, particularly when objective of effort is to demonstrate supposed self-contained and research existing in field. In this inherently political exercise, Kirton is tracing boundaries of field as he sees it, and in so doing, defining its important theoretical questions and traditions, thereby effectively marginalizing or dismissing other questions and traditions as less significant, perhaps irrelevant, and certainly not consistent with coherent research tradition that he believes now defines field. As such, practice, purpose, and perils ofthe list-making enterprise merit serious discussion, which we propose to undertake by looking both at Kirton's list, and at implicit messages behind list-making.THE PRACTICE OF LIST-MAKINGKirton begins his article by situating his own list-making effort within context of other lists. In particular, he looks at 2009 TRIP survey of top international relations /Canadian foreign policy scholars in order to establish a of scholars of Canadian foreign policy. He supplements this most influential with a of io books appearing on 25 undergraduate Canadian foreign policy 200809 syllabi available to him on web, which he deems most used textbook list. He then presents us with his of 10 important books on Canadian foreign policy. His criteria for selection of 10 important books, aside from being personal favourites, seem to include innovative ideas [that] stand at or near centre of field today (556). …

The centre is not in the middle: Evidence from line and word bisection

English and German readers have been shown to mark a position to the left of the true centre as the subjective midpoint in word bisection. This effect resembles a well-known phenomenon observed with the bisection of solid lines (pseudoneglect), although this behavioural similarity does not imply a common origin. The purpose of the present study was twofold: on the one hand, to investigate the perceptual and lexical features that influence the bisection of Italian orthographic strings and, on the other hand, to investigate whether identical or partially independent processing mediate bisection of line and orthographic stimuli. Five experiments were carried out to explore to what extent stimulus type (lines, words, pseudowords, consonant strings, symbols), stimulus length (from 3 to 13 characters), list context (pure and mixed), and written word frequency (high and low) affected the bisection performance. The results showed that list context modulated the processing similarities across different materials and that word frequency failed to influence the magnitude of the bisection bias. More critically, across all five experiments, the results showed different effects for solid lines versus orthographic material. Lines were always bisected to the left, independent of length and list context. By contrast, a crossover effect emerged with orthographic material; for long stimuli (above five letters) the bias was consistently to the left, while short stimuli showed a consistent rightward bias. The results indicate that manual bisection involved partly different cognitive mechanisms during word and line perception and that this may depend on the characteristics of the stimuli (words/discrete vs. lines/continuous).

Core Journal Lists: Classic Tool, New Relevance

Reviews the historical context of core journal lists, current uses in collection assessment, and existing methodologies for creating lists. Outlines two next generation core list projects developing new methodologies and integrating novel information/data sources to improve precision: a national-level core psychology list and the other a local institutional core list for the interdisciplinary field of urban studies and planning. The paper is based on the authors’ panel presentation at the 2009 ACRL National Conference (Seattle, Washington) titled “Core Journal Lists Re-viewed and Re-imagined.”

Pathway control in visual word processing: Converging evidence from recognition memory

The extent to which readers can exert strategic control over oral reading processes is a matter of debate. According to the pathway control hypothesis, the relative contributions of the lexical and nonlexical pathways can be modulated by the characteristics of the context stimuli being read, but an alternative time criterion model is also a viable explanation of past results. In Experiment 1, subjects named high- and low-frequency regular words in the context of either low-frequency exception words (e.g., pint) or nonwords (e.g., flirp). Frequency effects (faster pronunciation latencies for high-frequency words) were attenuated in the nonword context, consistent with the notion that nonwords emphasize the characteristics of the frequency-insensitive nonlexical pathway. Importantly, we also assessed memory for targets, and a similar attenuation of the frequency effect in recognition memory was observed in the nonword condition. Converging evidence was obtained in a second experiment in which a variable that was more sensitive to the nonlexical pathway (orthographic neighborhood size) was manipulated. The results indicated that both speeded pronunciation performance and memory performance were relatively attenuated in the low-frequency exception word context in comparision with the nonword context. The opposing influences of list context type for word frequency and orthographic neighborhood size effects in speeded pronunciation and memory performance provide strong support for the pathway control model, as opposed to the time criterion model.

Remembering words not presented in sentences: how study context changes patterns of false memories.

People falsely endorse semantic associates and morpheme rearrangements of studied words at high rates in recognition testing. The coexistence of these results is paradoxical: Models of reading that presume automatic extraction of meaning cannot account for elevated false memory for foils that are related to studied stimuli only by their visual form; models without such a process cannot account for false memory for semantic foils. Here we show how sentence and list study contexts encourage different encoding modes and consequently lead to different patterns of memory errors. Participants studied compound words, such as tailspin and floodgate, as single words or embedded in sentences. We show that sentence contexts led subjects to be better able to discriminate conjunction lures (e.g., tailgate) from old words than did list contexts. Conversely, list contexts led to superior discrimination of semantic lures (e.g., nosedive) from old words than did sentence contexts.

Integrative priming occurs rapidly and uncontrollably during lexical processing.

Lexical priming, whereby a prime word facilitates recognition of a related target word (e.g., nurse --> doctor), is typically attributed to association strength, semantic similarity, or compound familiarity. Here, the authors demonstrate a novel type of lexical priming that occurs among unassociated, dissimilar, and unfamiliar concepts (e.g., horse --> doctor). Specifically, integrative priming occurs when a prime word can be easily integrated with a target word to create a unitary representation. Across several manipulations of timing (stimulus onset asynchrony) and list context (relatedness proportion), lexical decisions for the target word were facilitated when it could be integrated with the prime word. Moreover, integrative priming was dissociated from both associative priming and semantic priming but was comparable in terms of both prevalence (across participants) and magnitude (within participants). This observation of integrative priming challenges present models of lexical priming, such as spreading activation, distributed representation, expectancy, episodic retrieval, and compound cue models. The authors suggest that integrative priming may be explained by a role activation model of relational integration. (PsycINFO Database Record (c) 2009 APA, all rights reserved).

Investing in movies

Investment managers are becoming increasingly interested in intellectual property as an asset class, and a large part of this intellectual property is filmed content created by the major movie studios. We have collected reliable information about the creative content and financial performance of feature films, and used this data to better understand the returns to investing in movies. We describe the valuation context of feature films and list the important factors influential in explaining financial returns. These factors are then used to build a quantitative, multiple factor valuation and risk model of the asset class.
