Bingyi Liu; Keke Yu; John W. Schwieter; Peiling Sun; Ruiming Wang – International Journal of Bilingual Education and Bilingualism, 2024
The relationship between language switching and task switching has been well studied in bilingualism literature. This study employs novel experiments involving magnitude-parity switching and transparency-orientation switching and compares the costs associated with these two types of task switching with language switching. Switching costs and the…

Spinelli, Elsa; Kandel, Sonia; Guerassimovitch, Helena; Ferrand, Ludovic – Language and Cognitive Processes, 2012
"AU" /o/ and "AN" /a/ in French are both complex graphemes, but they vary in their strength of association to their respective sounds. The letter sequence "AU" is systematically associated to the phoneme /o/, and as such is always parsed as a complex grapheme. However, "AN" can be associated with either one…

Moriya, Hiroki; Nittono, Hiroshi – Neuropsychologia, 2011
In order to determine the processing stage that is responsible for the effect of mood states on the breadth of attentional focus, we recorded event-related potentials from 18 students who performed a flanker task involving adjacent letters. To induce a specific mood state, positive, neutral, or negative affective pictures were presented repeatedly…

Middlebrooks, Paul G.; Sommer, Marc A. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2011
This study investigated whether rhesus monkeys show evidence of metacognition in a reduced, visual oculomotor task that is particularly suitable for use in fMRI and electrophysiology. The 2-stage task involved punctate visual stimulation and saccadic eye movement responses. In each trial, monkeys made a decision and then made a bet. To earn…

Pontifex, Matthew B.; Raine, Lauren B.; Johnson, Christopher R.; Chaddock, Laura; Voss, Michelle W.; Cohen, Neal J.; Kramer, Arthur F.; Hillman, Charles H. – Journal of Cognitive Neuroscience, 2011
The influence of cardiorespiratory fitness on the modulation of cognitive control was assessed in preadolescent children separated into higher- and lower-fit groups. Participants completed compatible and incompatible stimulus-response conditions of a modified flanker task, consisting of congruent and incongruent arrays, while ERPs and task…

Renoult, Louis; Debruille, J. Bruno – Journal of Cognitive Neuroscience, 2011
The N400 ERP is an electrophysiological index of semantic processing. Its amplitude varies with the semantic category of words, their concreteness, or whether their meaning matches that of a preceding context. The results of a number of studies suggest that these effects could be markedly reduced or suppressed for stimuli that are repeated.…

Kamienkowski, Juan E.; Pashler, Harold; Dehaene, Stanislas; Sigman, Mariano – Cognition, 2011
Does extensive practice reduce or eliminate central interference in dual-task processing? We explored the reorganization of task architecture with practice by combining interference analysis (delays in dual-task experiment) and random-walk models of decision making (measuring the decision and non-decision contributions to RT). The main delay…

Donk, Mieke; Soesman, Leroy – Journal of Experimental Psychology: Human Perception and Performance, 2010
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…

Adams, Zachary W.; Roberts, Walter M.; Milich, Richard; Fillmore, Mark T. – Psychological Assessment, 2011
Increased intraindividual variability in response time (RTSD) has been observed reliably in attention-deficit/hyperactivity disorder (ADHD) and has often been used as a measure of inattention. RTSD is assumed to reflect attentional lapses and distractibility, though evidence for the validity of this connection is lacking. We assessed whether RTSD…

Unsworth, Nash; Redick, Thomas S.; Lakey, Chad E.; Young, Diana L. – Intelligence, 2010
A latent variable analysis was conducted to examine the nature of individual differences in lapses of attention and their relation to executive and fluid abilities. Participants performed a sustained attention task along with multiple measures of executive control and fluid abilities. Lapses of attention were indexed based on the slowest reaction…

Carroll, Susanne E. – International Review of Applied Linguistics in Language Teaching (IRAL), 2012
Sentence position and word length have been claimed to contribute to the perceptual salience of words. The perceptual salience of words in turn is said to predict L2 developmental sequences. Data for such claims come from sentence repetition tasks that required perceptual re-encoding of input and that did not control for focal accent. We used a…

Cappelletti, Marinella; Lee, Hwee Ling; Freeman, Elliot D.; Price, Cathy J. – Journal of Cognitive Neuroscience, 2010
Neuropsychological and functional imaging studies have associated the conceptual processing of numbers with bilateral parietal regions (including intraparietal sulcus). However, the processes driving these effects remain unclear because both left and right posterior parietal regions are activated by many other conceptual, perceptual, attention,…

Roivainen, Eka – Learning and Individual Differences, 2011
A review of recent large-scale studies on gender differences in processing speed and on the cognitive factors assumed to affect processing speed was performed. It was found that females have an advantage in processing speed tasks involving digits and alphabets as well as in rapid naming tasks while males are faster on reaction time tests and…

Back, Elisa; Apperly, Ian A. – Cognition, 2010
A recent study by Apperly et al. (2006) found evidence that adults do not automatically infer false beliefs while watching videos that afford such inferences. This method was extended to examine true beliefs, which are sometimes thought to be ascribed by "default" (e.g., Leslie & Thaiss, 1992). Sequences of pictures were presented in which the…

Shin, Jacqueline C. – Brain and Cognition, 2011
The ability to learn temporal patterns in sequenced actions was investigated in elementary-school age children. Temporal learning depends upon a process of integrating timing patterns with action sequences. Children ages 6-13 and young adults performed a serial response time task in which a response and a timing sequence were presented repeatedly…
