Lexicality, morphological structure, and semantic transparency in the processing of German ver-verbs: The complementarity of on-line and off-line evidence

Two types of experiments investigate the visual on-line and off-line processing of German ver-verbs (e.g., verbittern ‘to embitter'). In Experiments 1 and 2 (morphological priming), latency patterns revealed the existence of facilitation effects for the morphological conditions (BITTER-VERBITTERN and BITTERN-VERBITTERN) as compared to the neutral conditions (SAUBER-VERBITTERN and SÄUBERN-VERBITTERN). In Experiments 3 and 4 (rating tasks) participants had to judge whether the target (VERBITTERN) “comes from,” “contains a form of,” or “contains the meaning of” the root (BITTER) or the root+en substring (BITTERN). Taken together, these studies revealed the combined influence of the three factors of lexicality (real word status), morphological structure, and semantic transparency.     

Inward, Outward, and Upward: Cognitive Aspects of Prayer

Recent investigations concerning ways people employ prayer typically suffer from either a fundamentally atheoretical approach or an indiscriminant mixing of affective, behavioral, and cognitive components. The present study examines the theory that a general concept of prayer–as–connection contains prayers of inward (connection with oneself), outward (human–human connection), or upward (human–divine connection) foci. Participants rated words or phrases according to what they "thought about" while praying. Factor analysis revealed eight primary factors: two inward, four outward, and two upward. Three second–order factors emerged (two outward and one upward). However, no general factor appeared.     

Phase correction, phase resetting, and phase shifts after subliminal timing perturbations in sensorimotor synchronization.

Recent studies of synchronized finger tapping have shown that perceptually subliminal phase shifts in an auditory sequence are rapidly compensated for in the motor activity (B. H. Repp, 2000a). Experiment 1 used a continuation-tapping task to confirm that this compensation is indeed a phase correction, not an adjustment of the central timekeeper period. Experiments 2-5 revealed that this phase correction occurs even when there is no ordinary sensorimotor asynchrony--when the finger taps are in antiphase or arbitrary phase relative to the auditory sequence (Experiments 2 and 3) or when the tap coinciding with the sequence phase shift is withheld (Experiments 4 and 5). The phase correction observed in the latter conditions was instantaneous, which suggests that phase resetting occurs when the motor activity is discontinuous. A prolonged phase shift suggestive of overcompensation was observed in some conditions, which poses a challenge to pure phase correction models.     

Orthographic and Morphological Masked Priming Effects in Arabic: Evidence from Lexical Decision Task in Children with and Without Dyslexia

In this study, we conducted a lexical decision test using masked priming paradigm to examine the morphological and orthographic priming effects in word recognition. Morphologically related word pairs can be derivational, sharing the same root or not (pseudo derivational). However, the orthographically related pairs share the same letters in different positions. Two groups of native Arabic-speaking children (N?=?57) from grade 4 and 5 participated in this study: typical readers (n?=?39) and dyslexic readers (n?=?18). To examine whether a potential morphological priming effect is driven by semantic or orthographic properties of shared morphemes, we compared prime-target pairs with derivation morphology and pseudo-derivation word related pairs. Between groups comparisons showed that a priming effect occurred only in typical readers. Comparisons between conditions revealed that a priming effect only occurred for accuracy in derivational morphology. No priming effect occurred in reaction times (RTs) between groups or conditions. These results provide evidence for root-based word recognition in Arabic children and give support to semantically rather than orthographically driven lexical access.     

Morphological priming: Dissociation of phonological, semantic, and morphological factors

Previous experiments based on a masked-priming paradigm revealed robust morphological priming effects induced by two derivational morphemes in Hebrew: the root and the verbal pattern. However, considering the special characteristics of the masked-priming paradigm, the possible contributions of phonological and/or semantic factors to these morphological effects could not be firmly assessed. In the present study, the role of these factors in morphological priming was examined, using cross-modal presentation. Experiment 1 revealed that priming between morphologically related words in Hebrew is determined by higher level linguistic characteristics and cannot be reduced to phonological overlap. Experiment 2 confirmed that morphological priming occurs in Hebrew even when primes and targets are not semantically related but, nevertheless, increases with semantic similarity. The results support the claim that morphological priming cannot be accounted for by considering semantic and phonological factors alone, and they exemplify the potential of using both masked and cross-modal priming to examine morphological processing.     

Judging response-outcome relations: The role of response-outcome contingency,outcome probability,and method of information presentation

A series of four experiments investigated college students’ judgments of interevent contingency. Subjects were asked to judge the effect of a discrete response Itapping a wire) on the occurrence of a brief outcome (a radio’s buzzing). Pairings of the possible event-state combinations (response-outcome, response-no outcome, no response-outcome, no response-no outcome) were presented in a summary-table (Experiments 2 and 4), in an unbroken-time-line (Experimente 1, 2, and 4), or in a broken-time-line format (Experiment 3). Subjects judged the extent to which the response caused the outcome or prevented it from occurring. Across all methods of information presentation, judgments were a positive function of response-outcome contingency and outcome probability. In the unbroken-time-line condition, judgments of negative response-outcome contingencies were less extreme than judgments of equivalent positive contingencies. This asymmetry was smaller in the broken-time-line condition and in those conditions in which subjects were encouraged to segment an unbroken time line into discrete response outcome units. Finally, judgments of positive and negative relationships were generally symmetrical in the summary-table condition. Relative to the two time-line portrayals, summary table judgments were also less influenced by the overall probability of outcome occurrence. These judgment differences among format conditions suggest that, depending on the method of information presentation, subjects differently partition event sequences into discrete event pairings.     

The revelation effect: when disguising test items induces recognition

Documented here is a bias whereby items are more likely to be judged as having been presented beforehand if they are disguised in some way and so have to be discovered or "revealed." The bias was found for test words that were unfolded letter by letter (Experiments 1 and 3), presented with their letters either transposed (Experiments 2 and 3), or individually rotated (Experiments 4 and 5), or rotated as a whole (Experiment 5), and for test numbers that were presented in the form of roman numerals (Experiment 6) or equations (Experiment 7). The bias occurred both for items that were presented beforehand and for those that were not. No bias was found when words were judged, not for prior occurrence, but for typicality as category instances (Experiment 8), lexicality (Experiment 9), frequency of general usage (Experiment 10), or number of times encountered during the preceding week (Experiment 11).     

Cognate status and cross-script translation priming

Greek-French bilinguals were tested in three masked priming experiments with Greek primes and French targets. Related primes were the translation equivalents of target words, morphologically related to targets, or phonologically related to targets. In Experiment 1, cognate translation equivalents (phonologically similar translations) showed facilitatory priming, relative to matched phonologically related primes, in conditions in which morphologically related primes showed no effect (50-msec prime exposure). Cross-language morphological priming emerged at longer prime exposure durations (66 msec), but cognate primes continued to generate more priming than did those in the morphological condition. In Experiments 2 and 3, the level of phonological overlap across translation equivalents was varied, and priming effects were measured against those for matched phonologically related primes and those in an unrelated prime condition. When measured against the unrelated baseline, cognate primes showed the typical advantage over noncognate primes. However, this cognate advantage disappeared when priming was measured against the phonologically related prime condition. The results are discussed in terms of how translation equivalents are represented in bilingual memory.     

Recollection, fluency, and the explicit/implicit distinction in artificial grammar learning

In this article, the authors propose that both implicit memory and implicit learning phenomena can be explained by a common set of principles, in particular via participants' strategic use of recollective and fluency heuristics. In a series of experiments, it was demonstrated that manipulating processing fluency had an impact on classification decisions in an artificial grammar learning task (Experiments 1, 2, 4, and 7), showing that participants were using a fluency heuristic. Under identical conditions, however, this manipulation had no effect on recognition decisions (Experiments 3 and 5), consistent with a greater default reliance on recollection. Most significant, the authors also showed that a fluency effect can be induced in recognition (Experiments 4-6) and can be eliminated in classification (Experiment 7).     

The contribution of morphological and semantic relatedness to repetition priming at short and long lags: Evidence from hebrew

The effect of morphological repetition at lag 0 and at lag 15 on lexical decision was investigated in Hebrew with three types of relation between prime and target. In the semantic-plus-morphological condition (SM), the prime and the target in each pair were two semantically related derivatives of the same root. In the “pure morphological” condition (M), the prime and the target derived from the same root, but their semantic association was very low, or nonexistent. In the semantic priming condition (S), primes and targets were semantically associated but were not morphologically related. The pure semantic relationship produced a significant facilitation at lag 0 that disappeared completely at lag 15. The pure morphological relation produced (smaller but) significant facilitation at lag 0 that was not attenuated at lag 15. When prime and target were semantically as well as morphologically related, the facilitation at lag 0 was similar to semantic priming, whereas at lag 15 it was similar to the pure morphological effect. Significant repetition effects at both lags were also found with non-words that shared the same (nonsensical) root and differed with respect to real derivational affixes. The differential time course for facilitation due to semantic and morphological relatedness suggests distinct underlying processes, although at lag 0 it is possible that semantic relatedness may augment the morphological repetition effect. Morphological repetition probably facilitates the retrieval of lexical information that, under certain circumstances, is necessary for lexical decision.     

Describing a group in positive terms reduces prejudice less effectively than describing it in positive and negative terms

In a series of five experiments, we demonstrate that exposure to information related to an out-group's heterogeneity reduces prejudice more effectively than exposure to only positive characteristics of the out-group. We exposed participants to a poster that associated both positive and negative traits with an out-group (mixed condition), to a poster that associated only positive traits with the out-group (positive condition), or to no poster (control condition). Results revealed that participants in the mixed condition expressed less explicit prejudice (Experiments 1–2) and less implicit bias (Experiments 3–4) than participants in the other two conditions. The last experiment demonstrated that the mixed poster was more acceptable and created less reactance than the positive poster. The results suggest that a persuasive message highlighting both the positive and negative characteristics of the out-group reduces prejudice more effectively because it is easily acceptable and yet effectively modifies people's representation of the out-group.     

List context fosters semantic processing: parallels between semantic and morphological facilitation when primes are forward masked

The authors examined patterns of facilitation under forward-masked priming conditions across 3 list contexts (Experiments 1-3) that varied with respect to properties of filler trials -- (a) mixed (morphological, orthographic, semantic), (b) identity, and (c) semantic -- but held the relatedness proportion constant (75%). Facilitation for targets that were related morphologically to their prime occurred regardless of filler context, but facilitation for semantically related pairs occurred only in the context of identity and semantic fillers. Facilitation was absent for orthographically similar prime-target pairs in all 3 filler contexts when matching numbers of orthographically similar word-word and word-nonword prime-target pairs rendered orthographic similarity uninformative with respect to lexicality of the target. Enhanced semantic and morphological facilitation in the context of identity and semantic relative to mixed fillers support a semantically attuned, as contrasted with a purely form-based, account of early morphological processing.     

Dissociative prime-probe contextual similarity effects on negative priming and repetition priming: a challenge to episodic retrieval as a unified account of negative priming

This study examined the dependence of repetition priming (RP) and negative priming (NP) as a function of prime-probe contextual similarity in a paradigm in which participants were required to respond to a letter flanked by incompatible distractor letters (e.g., ABA). Experiment 1 used prime and probe displays containing a pair of "+" symbols that were presented horizontally or vertically. Experiments 2 and 3 manipulated whether the letter triplets contained the "!" symbol. In all experiments, regardless of whether the RP trials were intermixed with the NP trials (Experiment 2) or not (Experiment 3), RP was stronger in the prime-probe similar conditions than in the prime-probe dissimilar conditions, but NP was independent of prime-probe contextual similarity. These findings suggest that NP is not necessarily stronger in conditions in which episodic retrieval of the prime is more likely.     

Social exclusion and the deconstructed state: time perception, meaninglessness, lethargy, lack of emotion, and self-awareness

The authors hypothesize that socially excluded individuals enter a defensive state of cognitive deconstruction that avoids meaningful thought, emotion, and self-awareness, and is characterized by lethargy and altered time flow. Social rejection led to an overestimation of time intervals, a focus on the present rather than the future, and a failure to delay gratification (Experiment 1). Rejected participants were more likely to agree that "Life is meaningless" (Experiment 2). Excluded participants wrote fewer words and displayed slower reaction times (Experiments 3 and 4). They chose fewer emotion words in an implicit emotion task (Experiment 5), replicating the lack of emotion on explicit measures (Experiments 1-3 and 6). Excluded participants also tried to escape from self-awareness by facing away from a mirror (Experiment 6).     

Recognition of letters traced in the right and left palms: Evidence for a process-oriented tactile asymmetry

Three experiments were conducted to examine the relative ability of the cerebral hemispheres to identify capital letters traced in the palms of the hands. In Experiment 1, letters were presented either right side up or upside down, and the subject's task was to name the letter aloud or point to an identical letter using the stimulated hand. Analysis of the accuracy data revealed that the left palm/right hemisphere (LP/RH) performed this task significantly better than did the right palm/left hemisphere (RP/LH), particularly when the stimuli were presented in the upside-down orientation. In Experiments 2 and 3, subjects performed the same letter identification task; however, on half the trials, they were required to maintain either a spatial or verbal concurrent memory load (i.e., a 24-point Vanderplas & Garvin form or six low-imagery nouns, respectively). In the no-load condition of Experiment 2 (spatial forms), the previously observed LP/RH advantage was replicated. However, in the load condition, this LP/RH superiority was no longer in evidence. In Experiment 3 (low-imagery nouns), the presence of a concurrent verbal task had minimal impact on the previously observed performance asymmetry as the LP/RH advantage was obtained in both the no-load and load conditions. The results of the three studies taken in composite suggest that (1) the operations utilized to identify letters traced in the palms of the hands are primarily spatial in nature and (2) that the observed performance asymmetry may be attributed to a right hemisphere superiority for the analysis and codification of information along a spatial dimension. These findings are discussed in terms of a "process-oriented" model of hemispheric asymmetry.     

The Thermometer of Social Relations: Mapping Social Proximity on Temperature

ABSTRACT— "Holding warm feelings toward someone" and "giving someone the cold shoulder" indicate different levels of social proximity. In this article, we show effects of temperature that go beyond these metaphors people live by. In three experiments, warmer conditions, compared with colder conditions, induced (a) greater social proximity, (b) use of more concrete language, and (c) a more relational focus. Different temperature conditions were created by either handing participants warm or cold beverages (Experiment 1) or placing them in comfortable warm or cold ambient conditions (Experiments 2 and 3). These studies corroborate recent findings in the field of grounded cognition revealing that concrete experiences ground abstract concepts with which they are coexperienced. Our studies show a systemic interdependence among language, perception, and social proximity: Environmentally induced conditions shape not only language use, but also the perception and construal of social relationships.     

Transposed-Letter Priming Across Inflectional Morpheme Boundaries

This study reports findings from two experiments testing whether a transposed-letter (TL) priming effect can be obtained when the transposition occurs across morphological boundaries. Previous studies have primarily tested derivationally complex words or compound words, but have not examined a more rule-based and productive morphological structure, i.e., inflectionally complex words, using masked priming. Experiment 1 tested TL priming with nonword primes and inflected targets (FOCUSING). Nonword primes were formed by transposing letters either within the root morpheme (fcousing) or across two morphemes (focuisng). Experiment 2 used the same nonword primes, but had the root words as targets (FOCUS). Both experiments showed similar TL priming effects for within-morpheme and across-boundary positions, indicating that morphological decomposition takes place only after letter positions in a word have been assigned. This finding provides additional evidence to previous research testing derived and compound words showing TL priming regardless of the position of transposition.     

Inflection,frequency, and the word superiority effect

Summary It has been known for nearly 100 years that single words presented tachistoscopically are better recognized than arbitrary letter strings. The present experiments investigate the impact of the morphological structure of words and of word frequency on the word superiority effect. It has been shown that inflected word forms show higher reaction time and error scores in the lexical decision task and higher error scores in the Reicher-Wheeler paradigm. Word frequency also determines lexical decision time. However, no frequency effect in the Reicher-Wheeler paradigm could be found. The results are discussed in the framework of McClelland and Rumelhart's (1981) model of context effects in letter search.This paper is mainly (Experiments I and III) based on the first author's Habilitationsschrift from October, 1982 (cf. Günther 1983a).     

On-line processing of social stereotypes during spoken language comprehension

Four experiments investigated stereotype processing during the on-line comprehension of spoken sentences. Participants listened to a critical prime (terrorist) embedded in a sentence and then made lexical decisions to visually presented standard-related (bomb) or stereotype-related targets (Arab) or unrelated controls for both conditions. For Experiments 1A and 1B, the preceding context provided no contextual information about the critical prime. Targets were presented at prime offset (Experiment 1A) or 300 ms after prime offset (Experiment 1B). In Experiments 2A and 2B, the preceding context was biased towards the stereotype meaning of the critical prime. Visual targets were presented at prime offset (Experiment 2A) or 300 ms after prime offset (Experiment 2B). Experiment 1A revealed a priming effect, but only for the standard meaning (i.e., bomb) of the critical prime. This effect was further replicated in Experiments 1B, 2A and 2B; however, for these experiments, unlike Experiment 1A, the results revealed lexical inhibition for the stereotype meaning of the critical prime. That is, lexical decisions to the stereotype-related targets were actually slower than the stereotype-unrelated controls. The results are discussed in terms of current social cognitive models of stereotype processing.
