Does sunshine prime loyal? Affective priming in the naming task

Recent work has found an affective priming effect using the naming task: In pronouncing target words, pronunciation latencies were consistently shorter when the target (e.g., loyal) was preceded by an evaluatively congruent (e.g., sunshine) rather than incongruent prime word (e.g, rain). Using the naming task, no affective priming was found in the present studies irrespective of prime-set size and target-set size (Experiment 1), irrespective of stimulus-onset asynchrony (Experiment 2), and even when a nearly exact replication of previous work that demonstrated the effect was conducted (Experiment 3). Finally, bilingual German/English speakers exhibited strong associative priming, but no affective priming, in both the English as well as the German language (Experiment 4). The results show that priming for evaluatively related words is not a general finding.     

Facilitation versus inhibition in the masked priming same–different matching task

In the past years, growing attention has been devoted to the masked priming same–different task introduced by Norris and Kinoshita (2008 Norris, D. and Kinoshita, S. 2008. Perception as evidence accumulation and Bayesian inference: Insights from masked priming. Journal of Experimental Psychology: General, 137: 433–455. [Crossref], [Web of Science ®] , [Google Scholar], Journal of Experimental Psychology: General). However, a number of researchers have raised concerns on the nature of the cognitive processes underlying this task—in particular the suspicion that masked priming effects in this task are mostly inhibitory in nature and may be affected by probe–prime contingency. To examine the pattern of facilitative/inhibitory priming effects in this task, we conducted two experiments with an incremental priming paradigm using four stimulus–onset asynchronies (13, 27, 40, and 53 ms). Experiment 1 was conducted under a predictive-contingency scenario (probe–prime–target; i.e., “same” trials: HOUSE–house–HOUSE vs. house–water–HOUSE; “different” trials: field–house–HOUSE vs. field–water–HOUSE), while Experiment 2 employed a zero-contingency scenario (i.e., “same” trials: HOUSE–house–HOUSE vs. house–water–HOUSE; “different” trials: field–field–HOUSE vs. field–water–HOUSE). Results revealed that, for “same” responses, both facilitation and inhibition increased linearly with prime duration in the two scenarios, whereas the pattern of data varied for “different” responses, as predicted by the Bayesian Reader model.     

A short‐term perceptual priming account of spacing effects in explicit cued‐memory tasks for unfamiliar stimuli

Memory for repeated items improves when presentations are spaced during study. This effect is found in explicit memory tasks using different types of material, different experimental paradigms, and in different subject populations. Two experiments are described where the spacing effect was assessed on a yes/no recognition memory task using words and nonwords as targets. The main results showed that changing the font between repeated occurrences of targets at study did not affect the spacing effect for words, even under shallow encoding conditions, but effectively removed the spacing effect with nonwords. In both experiments, the font manipulation was made between subjects, ruling out explanations in terms of differential attention to particular font conditions. These results provide further support for short‐term perceptual priming accounts of the spacing effect: Semantically‐based repetition priming affects memory for words; perceptual priming mechanisms affect memory for nonwords.     

Revisiting the prime–probe contextual similarity effect on negative priming: The impact of cue variability

In previous studies on negative priming, the effect of prime–probe contextual similarity was not stable. On occasions, negative priming was greater when similar rather than different contexts were presented in a prime and a probe trial; however, at other times, negative priming was not affected by such manipulation. The current study demonstrates that the effect of contextual similarity can be optimised when cue variability is high. Cue variability was manipulated between-subject across Experiments 1a and 1b and as a within-subject variable in Experiment 2. Symbols were presented as contextual cues. The results indicated that when cue variability was high, the prime–probe contextual similarity effect was observed on negative priming; however, when cue variability was low, the contextual similarity effect and the negative priming effect were absent.     

Effect of articulatory suppression on task‐switching performance: Implications for models of working memory

In a series of experiments, we examine some effects of articulatory suppression in task switching. The results from Experiments 1a and 2a showed that switch costs in the articulatory suppression condition were larger than those in the control and tapping conditions when the switching cues were not provided. On the other hand, articulatory suppression did not have any effect on switch costs in Experiments 1b and 2b, where the switching cues were provided. In Experiment 3, using a computer‐assisted experimentation, this pattern of data was replicated in a two‐factor design with articulatory suppression and switching cues factors. The results indicate that a specific component in working memory, the phonological loop, might contribute to the performance in task switching, at least in situations where the external task cues were not available. The data reported here suggest that the phonological loop plays an important role in one of the executive control processes, and challenge the traditional idea that the slave systems are simply governed by the central executive in the working memory.     

Does test‐induced priming play a role in the creation of false memories?

We investigated the role of test‐induced priming in creating false memories in the Deese/Roediger‐McDermott (DRM) paradigm, in which subjects study lists of related words (bed, rest, awake) and then falsely recall or recognise a related word (sleep) on a later test. However, in experiments using three different procedures, we found that the number of related words tested prior to the critical word had surprisingly little impact on false recall and recognition. We manipulated the location of the critical item in tests of yes/no recognition, word‐stem cued recall, and part‐set cued recall. We consistently obtained high probabilities of false recall and recognition, but the probability was unaffected by the number of related items presented prior to the test of the critical item. Surprisingly, test‐induced priming of the critical item does not seem to play a large role in this memory illusion.     

Repetition priming in task switching: Do the benefits dissipate?

In task-switching research, one process that has been implicated as a possible source of switch cost is repetition priming. In four experiments, an examination was made of the claim that repetition priming dissipates over the interval between trials and thereby causes switch cost to decrease with increases in the response-cue interval (RCI). In Experiments 1 and 2, RCI was manipulated within participants, producing the standard RCI effect on switch cost. In Experiments3 and 4, RCI was manipulated between participants and had no effect on switch cost. The role of experimental design and the mixed pattern of effects on switch and repeat trials in Experiments1 and 2 suggest that a passive architectural process such as priming dissipation is not responsible for the RCI effect on switch cost. Repetition priming may still be responsible for some or all of switch cost, but it appears to be more stable over time than was previously thought.     

Implications of the Islamic revival for Christian‐Muslim dialogue in Asia

Abstract

After a review of the demographic balance between Christians and Muslims in Asia, this article looks at the different factors which influence the relations between them. A review of the growth of Christianity in Asia is then followed by an outline of the four phases of the spread of Islam and a survey of the causes of the contemporary Islamic revival in the region. Particular attention is devoted to the influence of Wahhabi ideas from what is now Saudi Arabia, the hopes engendered by the creation of Pakistan in 1947, the influence of the Palestinian struggle, the legacy of the Iranian Revolution of 1979, the consequences of the Gulf War of 1991, and the impact of al‐Qa'ida and the events of 11 September 2001. Recent tensions between Christians and Muslims in Indonesia and the Philippines are discussed, and the significance of the revivalist critique of modernity and the clash of values between anthropocentric liberalism and the theocentric system of revivalist Islam is assessed.     

Doesconal prime canal more thancinal? Masked phonological priming effects in Spanish with the lexical decision task

Evidence for an early involvement of phonology in word identification usually relies on the comparison between a target word preceded by a homophonic prime and an orthographic control (rait-RATE vs. raut-RATE). This comparison rests on the assumption that the two control primes are equally orthographically similar to the target. Here, we tested for phonological effects with a masked priming paradigm in which orthographic similarity between priming conditions was perfectly controlled at the letter level and in which identification of the prime was virtually at chance for both stimulus onset asynchronies (SOAs) (66 and 50 msec). In the key prime-target pairs, each prime differed from the target by one vowel letter, but one changed the sound of the initial c, and the other did not (cinal-CANAL vs. conal-CANAL). In the control prime-target pairs, the primes had the identical vowel manipulation, but neither changed the initial consonant sound (pinel-PANEL vs. ponel-PANEL). For both high- and low-frequency words, lexical decision responses to the target were slower when the prime changed the sound of the c than when it did not, whereas there was no difference for the controls at both SOAs. However, this phonological effect was small and was not significant when the SOA was 50 msec. The pattern of data is consistent with an early phonological coding of primes that occurs just a little later than orthographic coding.     

Adults’ perception of native and nonnative vowels: Implications for the perceptual magnet effect

Two experiments were conducted to evaluate the perceptual magnet effect. In Experiment 1, Amer-ican English speakers representing diverse dialects were presented with a fine-grained set of stimuli (varying in just noticeable differences forF1 andF2) and indicated whether they heard “/i/” or “not /i/,” thus delimiting the /i/ portion of the vowel space for individual subjects. Then these same subjects selected their own /i/ prototype with a method-of-adjustment procedure. The data from this experiment were used to synthesize customized prototype and nonprototype stimulus sets for Experiment 2. In Experiment 2,24 of our original 37 subjects completed a discrimination task for each of three conditions, in which vector stimuli varied from the subject’s prototype, the nonprototype, or a foreign vowel (/y/) in 15-mel steps. Subjects displayed higher discrimination, as indexed byd′, for the nonprototype condition than they did for both the prototype and the foreign conditions. In addition, discrimination was better for variants further away from the referent in each condition. However, discrimination was not especially poor for stimuli close to subjects’ individual prototypes—a result that would have yielded the strongest support for the operation of a magnet effect. This negative finding, together with other aspects of our results, raises problems for any theory of vowel perception that relies solely on “one-size-fits-all” prototype representations.     

Accounting for sequential trial effects in the flanker task: Conflict adaptation or associative priming?

The conflict-control loop theory proposes that the detection of conflict in information processing triggers an increase in cognitive control, resulting in improved performance on the subsequent trial. This theory seems consistent with the robust finding that conflict susceptibility is reduced following correct trials associated with high conflict: the conflict adaptation effect. However, despite providing favorable conditions for eliciting and detecting conflict-triggered performance adjustments, none of the five experiments reported here provide unequivocal evidence of such adjustments. Instead, the results corroborate and extend earlier findings by demonstrating that the conflict adaptation effect, at least in the flanker task, is only present for a specific subset of trial sequences that is characterized by a response repetition. This pattern of results provides strong evidence that the conflict adaptation effect reflects associative stimulus-response priming instead of conflict-driven adaptations in cognitive control.     

Does sunshine prime loyal … or summer? Effects of associative relatedness on the evaluative priming effect in the valent/neutral categorisation task

After 30 years of research, the mechanisms underlying the evaluative priming effect are still a topic of debate. In this study, we tested whether the evaluative priming effect can result from (uncontrolled) associative relatedness rather than evaluative congruency. Stimuli that share the same evaluative connotation are more likely to show some degree of non-evaluative associative relatedness than stimuli that have a different evaluative connotation. Therefore, unless associative relatedness is explicitly controlled for, evaluative priming effects reported in earlier research may be driven by associative relatedness instead of evaluative relatedness. To address this possibility, we performed an evaluative priming study in which evaluative congruency and associative relatedness were manipulated independently from each other. The valent/neutral categorisation task was used to ensure evaluative stimulus processing in the absence of response priming effects. Results showed an effect of associative relatedness but no (overall) effect of evaluative congruency. Our findings highlight the importance of controlling for associative relatedness when testing for evaluative priming effects.     

Prolonged development of auditory skills: A role for perceptual anchoring?

Many auditory skills continue to develop beyond infancy and even into adolescence, but the factors underlying this prolonged development remain poorly understood. Of interest here is the contribution of on-line statistical learning of stimulus repetitions (anchoring) to the development of auditory spectral and temporal discrimination, as well as the potential contributions of auditory attention and working memory. Children, aged 6–13 years, as well as adults (age range: 21–33 years) were tested on auditory frequency and duration discrimination. Each type of discrimination was measured in two conditions (XAB and XXXAB) designed to afford different levels of anchoring by varying the number of repetitions of a standard stimulus (X) prior to the presentation of the test tone (A or B) in each trial. Auditory attention and working memory were also assessed. Whereas duration and frequency discrimination in either condition did not reach adult level prior to 11 years of age, the magnitude of the anchoring effect was similar across ages. These data suggest that perceptual anchoring matures prior to the attainment of adult-like discrimination thresholds. Likewise, neither attention nor working memory could account for the observed developmental trajectories. That auditory discrimination and anchoring follow dissociable developmental trajectories suggests that different factors might contribute to the development of each. We therefore conclude that although anchoring might be necessary for attaining good auditory discrimination, it does not account for the prolonged development of auditory frequency and duration discrimination in school-aged children.     

The role of visual-auditory “compellingness” in the ventriloquism effect: Implications for transitivity among the spatial senses

A magnitude estimation response procedure was used to evaluate the strength of visualauditory intersensory bias effects under conditions of spatial discrepancy. Maj or variables were the cognitive compellingness of the stimulus situation and instructions as to the unity or duality of the perceptual event. With a highly compelling stimulus situation and single-event instructions, subjects showed a very high visual bias of audition, a significant auditory bias of vision, and a sum of bias effects that indicated that their perception was fully consonant with the assumption of a single perceptual event. This finding reopens the possibility that the spatial modalities function as a transitive system, an outcome that Pick, Warren, and Hay (1969) had expected but did not obtain. Furthermore, the results support the model for intersensory interaction proposed by Welch and Warren (1980) with respect to the susceptibility of intersensory bias effects to several independent variables. Finally, a new means of assessing intersensory bias effects by the use of spatial separation threshold was demonstrated.     

The role of task rules and stimulus–response mappings in the task switching paradigm

Switch costs occur whenever participants are asked to switch between two or more task sets. In a typical task switching experiment, participants have to switch between two task sets composed of up to four different stimuli per task set. These 2 (task sets) x 4 (stimuli) contain only 8 different stimulus-response (S-R) mappings, and the question is why participants base their task performance on task sets instead of S-R mappings. The current experiments compared task performance based on task rules with performance based on single stimulus-response mappings. Participants were led to learn eight different S-R mappings with or without fore-knowledge about two underlying task sets. Without task set information no difference between shifts and repetitions occurred, whereas introducing task sets at the beginning led to significant switch costs. Most importantly, introducing task sets in the middle of the experiment also resulted in significant switch costs. Furthermore, introducing task rules at the beginning of the experiment lead to slower RTs when simple stimuli (Experiment 1) had to be processed. This detrimental effect disappeared with more complex stimuli (Experiment 2). Results will be discussed with respect to cognitive control.     

When do primes prime? The moderating role of the self-concept in individuals’ susceptibility to priming effects on social behavior

Using cooperative behavior in economic decision-making settings, we predicted and found that people’s susceptibility to priming influences is moderated by two factors: people’s chronic accessibility to a behavioral repertoire and people’s self-concept activation. In Experiment 1, we show that individuals highly consistent in their social value orientation (SVO) assimilate their behavior to their dispositions rather than to the primes, whereas the opposite effect is obtained among individuals with a low consistent SVO. In Experiment 2, we show that low consistent SVO individuals become less susceptible to priming influences when their self-concept is activated. These studies shed new light on individuals’ susceptibility to priming influences on social behavior.     

Load theory of selective attention and the role of perceptual load: Is it time for revision?

Perceptual load hypothesis is proposed as a compromise between early and late theory of selective attention which states that the selection will operate early when the load on perception is high and it will operate late when the load on perception is low. Experimental findings have shown that the perceptual load hypothesis is too simplistic in nature as perceptual load is not the only determinant of selection processes. It is difficult to apply the load hypothesis to explain the occurrence of early selection in low load displays as well as the selection processes that operate on distractor and target stimuli that are a part of the same object. Factors like spatial proximity, cues that manipulate the spatial extent of attentional focus, salience of targets as well as the distractors, and perceptual grouping between the target and the distractors should be taken into account while explaining the selective control of attention. Thus, the perceptual load of the display is one such factor that affects selective attention and goal-directed behaviour, but it is not the only factor to affect the selective control of attention.     

Screen Christologies: An evaluation of the role of Christ‐figures in film

Throughout the course of Christian history, the nature and identity of Jesus Christ has been interpreted in a wide variety of ways. In this article, I will suggest that the root tensions between the divine and human natures of Christ, as epitomized in the Alexandrian and Antiochene controversies of the Patristic Church, find a contemporary expression in the abundance of Christ‐figures that have emerged in contemporary film. Attention will be given to the functions that such figures perform, and their relationship to the Person of Christ as understood by the respective ‘high’ (Alexandrian) and ‘low’ (Antiochene) schools of Christology. I will conclude that, provided sufficient emphasis is placed on the humanity of the Christ‐figure, a process of redemption analogous to that found in traditional Christian accounts of the Person of Christ is operative through such films.     

Does test-induced priming play a role in the creation of false memories?

We investigated the role of test-induced priming in creating false memories in the Deese/Roediger-McDermott (DRM) paradigm, in which subjects study lists of related words (bed, rest, awake) and then falsely recall or recognise a related word (sleep) on a later test. However, in experiments using three different procedures, we found that the number of related words tested prior to the critical word had surprisingly little impact on false recall and recognition. We manipulated the location of the critical item in tests of yes/no recognition, word-stem cued recall, and part-set cued recall. We consistently obtained high probabilities of false recall and recognition, but the probability was unaffected by the number of related items presented prior to the test of the critical item. Surprisingly, test-induced priming of the critical item does not seem to play a large role in this memory illusion.     

Exploring the time course of semantic interference and associative priming in the picture–word interference task

The picture–word interference (PWI) task is a widely used technique for exploring effects of semantic context on lexical access. In this task, printed words are superimposed over pictures to be named, with the timing of the interfering word relative to the picture systematically manipulated. Two experiments (N = 24 adults in each) explored the time course of effects of associates (e.g., CARROT superimposed on a picture of a rabbit) versus coordinates (e.g., CHIPMUNK superimposed on a picture of a rabbit) on naming latencies. Associates led to faster picture naming than did unrelated words, with facilitative effects occurring at stimulus onset asynchronies (SOAs, in ms) ranging from –450 to 0. Coordinates led to slower naming latencies, with the interference effect restricted to SOAs of –150 and 0. The overlapping time course of associative priming and coordinate interference provides important constraints on models of lexical access in speech production.
