Salience is only briefly represented: Evidence from probe-detection performance.

Salient objects in the visual field tend to capture attention. The present study aimed to examine the time-course of salience effects using a probe-detection task. Eight experiments investigated how the salience of different orientation singletons affected probe reaction time as a function of stimulus onset asynchrony (SOA) between the presentation of a singleton display and a probe display. The results demonstrate that salience consistently affected probe reaction time at the shortest SOA. The effect of salience disappeared as SOA increased. These results suggest that contrary to the assumption of major theories on visual selection, salience is transiently represented in our visual system allowing the effects of salience on attentional selection to be only short-lived.

Associative priming in bilinguals: Some limits of interlingual facilitation effects.

Examined how the prior visual presentation of a word from one of a bilingual S's languages can facilitate the identification of an associated word from the other language. Results from performance on lexical decision tasks with 72 Ss show a different pattern of effects for intra- and interlingual conditions at 2 different stimulus onset asynchronies (SOAs). At a short SOA, no facilitation effect was observed between associated words from different languages. At a long SOA, facilitation was observed for both between- and within-language conditions, but the between-language effect was weaker. Results do not suggest direct interlingual links in the bilingual lexicon. (French abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reading aloud is not automatic: Processing capacity is required to generate a phonological code from print.

The present experiments tested the claim that phonological recoding occurs "automatically" by assessing whether it uses central attention in the context of the psychological refractory period paradigm. Task 1 was a tone discrimination task and Task 2 was reading aloud. The joint effects of long-lag word repetition priming and stimulus onset asynchrony (SOA) were underadditive in Experiment 1, suggesting that an early component of lexical processing does not use central attention. In contrast, nonword letter length and grapheme-phoneme complexity yielded additive effects with SOA in Experiments 2, 3, and 4, suggesting that assembled phonology uses central attention. Further, orthographic neighborhood density also yielded additive effects with SOA in Experiments 5, 6, and 7, suggesting that lexical contributions to phonological recoding use central attention. Taken together, the results of these experiments are inconsistent with the widespread claim that phonological codes are assembled and/or addressed automatically. It is suggested that "automaticity" should be replaced by accounts that make more specific claims about how processing unfolds. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Conditioned preferences in the rat with an unnatural need state: Morphine withdrawal.

Placed 30 morphine addicted and 15 nonaddicted female albino rats on a 21-day conditioning regimen which involved the daily alternation of access to either water, sucrose-octa-acetate (SOA), or no liquid for 1 hr. The addicted Ss received injections of morphine after either the SOA sessions or the no-liquid sessions. Nonaddicted Ss were injected with morphine after the SOA sessions. Following the last injection, Ss were given a 2-bottle preference test between SOA and water. Results show that the addicted Ss that received morphine-SOA pairings had an increased preference for SOA, whereas the nonaddicted Ss showed a decrease in SOA preference after the same conditioning treatments. Addicted Ss that received the morphine injections on the no-liquid days showed no change in SOA preference. (21 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Concurrent response-selection processes in dual-task performance: Evidence for adaptive executive control of task scheduling.

This article reports 4 experiments that used the psychological refractory period procedure to characterize how people perform multiple tasks concurrently. For each experiment, a primary choice-reaction task was paired with a secondary choice-reaction task that had two levels of response-selection difficulty. Experiments 1 and 2 varied secondary-task response-selection difficulty by manipulating the number of stimulus-response (S-R) pairs. The effect of this factor on secondary-task reaction times (M) decreased reliably as the stimulus onset asynchrony (SOA) decreased. Experiments 3 and 4 varied secondary-task response-selection difficulty by manipulating S-R compatibility. Again, the effect of this factor on secondary-task M decreased reliably as SOA decreased. These results raise doubts about the existence of an immutable structural response-selection bottleneck and suggest that response selection for 2 concurrent tasks may overlap temporally.

Cue search and comparison processes in visual search for letters.

In 2 experiments, each with 16 college students and laboratory staff members, Ss searched 4- and 8-letter arrays for the presence of a T or an F. The position of the target was indicated by a bar marker presented at 1 of 7 stimulus onset asynchronies (SOAs): –200, –25, 50, 125, 200, 275, or 350 msec. In Exp I, SOA conditions were blocked; in Exp II, SOA conditions varied randomly from trial to trial. In both experiments array size and SOA interacted. With 8-letter arrays, reaction time (RT) increased linearly with SOA with a slope less than 1. With 4-letter arrays, RT increased with SOA but reached asymptote at the level of no-cue control RTs at the 125-msec SOA. Results support the notion that cue search and comparison processes may function concurrently. (French summary) (18 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Exploiting degrees of inflectional ambiguity: Stem form and the time course of morphological processing.

The authors compared sublexical and supralexical approaches to morphological processing with unambiguous and ambiguous inflected words and words with ambiguous stems in 3 masked and unmasked priming experiments in Finnish. Experiment 1 showed equal facilitation for all prime types with a short 60-ms stimulus onset asynchrony (SOA) but significant facilitation for unambiguous words only with a long 300-ms SOA. Experiment 2 showed that all potential readings of ambiguous inflections were activated under a short SOA. Whereas the prime-target form overlap did not affect the results under a short SOA, it significantly modulated the results with a long SOA. Experiment 3 confirmed that the results from masked priming were modulated by the morphological structure of the words but not by the prime-target form overlap alone. The results support approaches in which early prelexical morphological processing is driven by morph-based segmentation and form is used to cue selection between 2 candidates only during later processing.

Phonological and semantic activation in reading kanji characters.

In a large proportion of the complex kanji characters resulting from the combination of two radicals, the left radical gives information about the meaning of the whole character, and the right one gives cues to pronunciation. In this study, this feature was exploited to investigate the relative contribution of semantic and phonological information in the process of recognizing a word written in kanji. In 2 experiments, a technique was used in which part of the target character (i.e.. the left radical, carrying the semantic information; the right, phonetic radical, or a fragment) was presented shortly (60 or 180 ms stimulus onset asynchrony [SOA]) before the exposure of the whole character, which had to be named as fast as possible. Earlier exposure of the phonetic radical produced facilitation of the naming response, which was stronger at the 180-ms SOA than at the 60-ms SOA, whereas preexposure of the semantic radical had a weak facilitatory effect at the 60-ms SOA and some inhibition at the 180-ms SOA.

Better to take one long or two quick looks? Independent processing of evidence from discrete visual presentations.

Should we prefer one long look to two quick looks of equal overall duration? The authors systematically compared conditions in which a circular letter array was available either for a single look of 2d ms duration (onset asynchrony [SOA] from target to mask) or for two separate looks of d ms each. On the basis of the geometry of the underlying psychometric function relating the SOA to the probability of target identification, separate activation models with peaked hazard functions predict that for short SOAs single long looks would lead to better identification performance and that this advantage decreases (and may turn into a disadvantage) with increasing SOA. These predictions were tested, confirmed, and extended in 5 letter-identification experiments that focused on the mechanism by which information extracted from single arrays is integrated across different looks.

Response latency of gerbils and hamsters to nuts flavoured with bitter-tasting substances

The unconditioned reactions of Mongolian gerbils to peanuts rolled in sucrose octa-acetate (SOA) or denatomium benzoate (Bitrex) were studied in Experiment 1. Although SOA evokes as high a bitterness rating among humans as quinine salts, the gerbils' latency to ingest a nut flavoured with the former was similar to that to an unflavoured nut. Their oral latency to a nut that was flavoured with Bitrex was longer than to either an unflavoured one or one flavoured with SOA. However, the fact that they ingested a nut flavoured with the "most bitter substance known to man" within 70 sec after contact is surprising. Experiment 2 dealt with the effects of a peanut that was either unflavoured or flavoured with SOA or quinine and then paired with a LiCl injection. The oral latency of these gerbils to a nut conveying such flavours was assessed for six days after this conditioning. A nut flavoured with quinine acquired aversive properties but not ones that were flavoured with SOA or were unflavoured. Similar results were observed in Experiment 3, when hamsters were tested under comparable conditions. The theoretical implications of these results are discussed.
