Reading aloud: spelling-sound translation uses central attention

Contrary to the received view that reading aloud reflects processes that are "automatic," recent evidence suggests that some of these processes require a form of attention. This issue was investigated further by examining the effect of a prior presentation of exception words (words whose spelling-sound translation are atypical, such as pint as compared with mint, hint, or lint) and pseudohomophones (nonwords that sound identical to words, such as brane from brain) on reading aloud in the context of the psychological refractory period paradigm. For exception words, the joint effects of repetition and stimulus onset asynchrony (SOA) yielded an underadditive interaction on the time to read aloud, replicating previous work -- a short SOA between Task 1 and Task 2 increased reaction time (RT) and reduced the magnitude of the repetition effect relative to the long SOA. For pseudohomophones, in contrast, the joint effects of repetition and SOA were additive on RT. These results provide converging evidence for the conclusion that (a) processing up to and including the orthographic input lexicon does not require central attention when reading aloud, whereas (b) translating lexical and sublexical spelling to sound requires the use of central attention.     

Facial affect and temporal order judgments: emotions turn back the clock

The influence of facial affect on the perception of temporal order was examined in the context of the temporal order judgment (TOJ) paradigm. Two schematic faces were presented either simultaneously, or separated by varying stimulus onset asynchronies (SOAs; -100 ms, -34 ms, -17 ms, 17 ms, 34 ms, 100 ms), and participants had to judge which face appeared first. Each schematic face displayed one of three emotions; happy, neutral, or angry. Facial affect was found to influence judgments of temporal order at short SOAs (-17 ms, 0 ms, and 17 ms) but not at the longest SOAs (-100 ms and 100 ms), consistent with the hypothesis that facial affect influences relative onset judgments when they are difficult to make.     

Disengaging attention: on the locus of the cue-duration effect in partial report.

Increasing cue duration impairs performance in bar-probe partial report when cues are presented peripherally, but not centrally (P. Dixon, R. Gordon, A. Leung, & V. Di Lollo, 1997). Three experiments examined whether this cue-duration effect reflects processes of exogenous attention. The effect of cue duration on partial report performance with peripheral, but not central, cues was replicated (Experiment 1). Further experiments manipulated the degree that exogenous versus endogenous modes of selection were favored and found that the cue-duration effect for peripheral cues was reduced (a) when blocks contained a high proportion of central cues (Experiment 2) and (b) when the color of the cue indicated the location of the target (Experiment 3). These findings challenge the view that the cue-duration effect is restricted to exogenous attention and are discussed in terms of the process of disengaging attention from the cue to reallocate attention to the target representation.

Spatial attention modulates feature crosstalk in visual word processing

One major idea about spatial attention is that it serves to modulate crosstalk between features during reading. Two reading aloud experiments are reported in which a cue-validity manipulation was combined with manipulations that are thought to increase the likelihood of feature-level crosstalk: interletter spacing and the presence or absence of irrelevant features. Both experiments yielded an interaction between the effects of spatial cuing and each of these factors. These results are taken to support the hypothesis that when spatial attention is focused on the word, it provides protection against crosstalk among features in the context of reading aloud.     

Dissociative effects of stimulus quality on semantic and morphological contexts in visual word recognition.

Semantic and morphological contexts were manipulated jointly with stimulus quality under conditions where there were few related prime-target pairs (i.e., low relatedness proportion) in a lexical decision experiment. Additive effects of semantic context and stimulus quality on RT were observed, replicating previous work. In contrast, morphological context interacted with stimulus quality. This dissociation is discussed in the context of Besner and colleagues' evolving multistage framework. The essence of the account is that 1) stimulus quality affects feature and letter levels, but not later levels, 2) feedback from semantics to the lexical level is inoperative under low relatedness proportion conditions (hence stimulus quality and semantic context yield additive effects), whereas 3) feedback from the lexical level to the letter level is intact, hence stimulus quality and morphological context produce an interaction by virtue of them affecting a common stage of processing.     

Implications of measures of reliability for theories of priming: Activity in semantic memory is inherently noisy and uncoordinated

In experiments on semantic priming, participants vary substantially in the absolute magnitude of priming they produce. Are these individual differences systematic or do they arise from random processes, and does the answer carry theoretical implications? To find out, we examined split‐half and test–retest reliability of semantic priming in a series of two‐session experiments that crossed relatedness proportion (RP, at .25, .50, and .75) with stimulus–onset asynchrony (SOA, at 200, 350, and 800 ms). Low reliability would indicate little coherence of activity within semantic memory, so that the degree to which any given association influences performance is uncorrelated from one association and time of testing to the next. High reliability would indicate that each person tends to harness his or her semantic knowledge consistently, applying semantic relations among words in much the same way from one word to the next and one time of testing to the next to help task performance, resulting in systematic individual differences. What we observed was low reliability—often zero. When conditions highlighted “automatic activation” (low RP, short SOA), priming was completely uncorrelated from item to item and session to session. Both split‐half and test–retest reliability increased to significant levels under conditions that raised the probability that an activated or retrieved episode of prime experience would help with target recognition, and the probability of intentionally generating the target from the prime. Thus, task‐relevant" utility imposes a modicum of order on semantic associations that are otherwise noisy and uncoordinated. Harnessing semantic memory is like herding cats—without considerable constraint, associations tend to come and go their own ways in independent fashion.
