Deficits in other-race face recognition: No evidence for encoding-based effects.
The other-race effect (ORE) in face recognition is typically observed in tasks which require long-term memory. Several studies, however, have found the effect early in face encoding (Lindsay, Jack, & Christian, 1991; Walker & Hewstone, 2006). In 6 experiments, with over 300 participants, we found no evidence that the recognition deficit associated with the ORE reflects deficits in immediate encoding. In Experiment 1, with a study-to-test retention interval of 4 min, participants were better able to recognise White faces, relative to Asian faces. Experiment 1 also validated the use of computer-generated faces in subsequent experiments. In Experiments 2 through 4, performance was virtually identical to Asian and White faces in match-to-sample, immediate recognition. In Experiment 5, decreasing target-foil similarity and disrupting the retention interval with trivia questions elicited a re-emergence of the ORE. Experiments 6A and 6B replicated this effect, and showed that memory for Asian faces was particularly susceptible to distraction; White faces were recognised equally well, regardless of trivia questions during the retention interval. The recognition deficit in the ORE apparently emerges from retention or retrieval deficits, not differences in immediate perceptual processing.

Featuring familiarity: How a familiar feature instantiation influences categorization.
We demonstrate that a familiar looking feature can influence categorization through 2 different routes, depending on whether a person is reliant on abstract feature representations or on concrete feature representations. In 2 experiments, trained participants categorized new category members in a 3-step procedure: Participants made an initial categorization, described the rule-consistent features indicated by the experimenter, and then recategorized the item. Critical was what happened on the second categorization after participants initially categorized an item based on a familiar, but misleading, feature. Participants who were reliant on abstract features most commonly reversed themselves after the rule-consistent features were pointed out, suggesting that the familiar feature had biased attention. Participants who were reliant on concrete feature representations, however, most commonly persisted with the initial response as if the familiar feature were more important than its rivals—the familiar feature biased decision making.

Difficulté des jeunes enfants à comprendre la dissimulation des émotions.
The authors investigated the understanding of emotion dissimulation in school-age children. Sixty participants were read short stories in which a main character expressed an emotion or hid an emotion from other characters. The participants were asked to identify the emotion felt by the main characters and to indicate the facial expressions they would display. Then they were asked what emotions the main characters felt while they were displaying these expressions, and what the beliefs of the other story characters would be as to the emotion felt by the main characters. The results revealed that children from 5 to 6 years of age have a partial understanding of emotion dissimulation. They were accurate in finding the emotion felt by the main characters when questioned the first time. They were also accurate in choosing the expressions the main characters would display to hide their emotions. However, they were often inaccurate as to the felt emotions of the main characters when questioned the second time. Compared with 9- and 10-year-olds, the younger children had more difficulty understanding the simultaneous character of felt and displayed emotions. Five- and 6-year-olds were also less accurate than the older children when asked to indicate the beliefs of the other characters in stories where felt emotions were hidden.

Further evidence that congenitally blind participants react faster to auditory and tactile spatial targets.
Congenital blindness is one of the rare human models to explore the role of experience-driven cross-modal compensation after early sensory deprivation. We re-examined spatial attention abilities in congenitally blind participants and sighted controls using a paradigm comparable to the one of our previous study (Collignon, Renier, Bruyer, Tranduy, & Veraart, 2006), except that this time the auditory and tactile stimuli were now presented in sequence. Although both groups performed the task with similar accuracy, we observed that blind participants had shorter reaction times than sighted controls for the detection of spatial targets in both sensory modalities. Moreover, this finding held true for both the selective and divided attention conditions. These results not only confirm previous reports on the superiority of the blind during auditory and tactile attention tasks, but also broaden our knowledge of the mechanisms underlying cross-modal compensation.

Illusions of competence for phonetically, orthographically, and semantically similar word pairs.
Illusions of competence are thought to arise when judgements of learning (JOLs) made in the presence of intact cue-target pairs during study create a “foresight bias,” such that JOLs are inflated by the apparent association between a cue and a target, despite the lack of benefit this association has for recall performance. For example, Castel, McCabe, and Roediger (2007) recently demonstrated an illusion of competence for identical word pairs (mouse—mouse). In two experiments, the authors examined possible sources for this overconfidence, including phonetic, semantic, and orthographic similarity. An illusion of competence was found for homophones, synonyms, orthographically similar, and unrelated items, whereas no illusion of competence was found for word pairs with a relatively high forward-semantic association. Self-paced study times indicated that encoding fluency was not closely associated with the magnitude of overconfidence. Error data revealed participants may have been engaging in strategic responding in order to maximise correct recall. Our results underscore the importance of considering factors that influence both JOLs and recall performance when considering sources of (mis)calibration in absolute accuracy.

L’amorçage orthographique masqué dans la reconnaissance des mots écrits: Données empiriques et perspectives théoriques.
The present paper reviews the main studies that have been conducted on the effects of masked orthographic priming in written word recognition. Empirical data accumulated over the last two decades are exposed by considering three factors that play a role in the effects of orthographic priming: prime lexicality, prime duration, and target and/or prime orthographic neighbourhood. The theoretical implications of these data are discussed in light of the two major frameworks of visual word recognition, the serial search and the interactive activation. As a whole, the interactive activation hypothesis seems to be more appropriate to account for the empirical data. (PsycINFO Database Record (c) 2009 APA, all rights reserved)
Flicker is a primitive visual attribute in visual search.
At the earliest processing stages, visual stimuli are decomposed by a set of filters tuned to specific values of such attributes as colour, orientation, and motion. These filters have been characterised both neurophysiologically and behaviourally. The single exception is the attribute of flicker that has been characterised neurophysiologically but not behaviourally. Using a visual search paradigm, the authors provide the first behavioural demonstration that flicker is indeed a primitive attribute used by the visual system in stimulus encoding. Consistent with the temporal contrast-sensitivity function, sensitivity to flicker was highest at about 10 Hz and decreased as the flicker rate was either increased or decreased.

Increasing the difficulty of response selection does not increase the switch cost.
Several theories of task switching assume that basic task processes such as stimulus identification and response selection do not contribute to task-switch costs. This conclusion is mainly based on the finding that stimulus-identification manipulations have no influence on the size of the switch cost. The present study tested the influence of response-selection manipulations on the size of the switch cost. The authors manipulated the difficulty of response selection by using a semantically based response-side effect that is associated with numerical-judgement tasks, namely the Spatial Numerical Association of Response Codes (SNARC) effect. The authors observed a SNARC effect and a switch cost, but no interaction between the two: the task-switch cost did not differ between SNARC-compatible and -incompatible responses. The authors conclude that response selection does not contribute to the switch cost on the current trial, which provides further support for the idea that basic task processes and task-switch processes are separate.

The optic tectum of birds: Mapping our way to understanding visual processing.
Over the past few decades there has been a massive amount of research on the geniculo-striate visual system in primates. However, studies of the avian visual system have provided a rich source of data contributing to our understanding of visual processing. In this paper we review the connectivity and function of the optic tectum (homolog of the superior colliculus) in birds. We highlight the retinotopic projections that the optic tectum has with the isthmal nuclei, and the functional topographic projections that the optic tectum has with the nucleus rotundus and entopallium (homologs of the pulvinar and extrastriate cortex, respectively) where retinotopy has been sacrificed. This work has been critical in our understanding of basic visual processes including attention, parallel processing, and the binding problem.
