subliminal mere exposure effect does not generalize to structurally related stimuli, The

subliminal mere exposure effect does not generalize to structurally related stimuli, The Newell, Ben R Abstract R.F. Bornstein (1994) questioned whether subliminal mere exposure effects might generalize to structurally related stimuli, thereby providing evidence for the existence of implicit learning. Two experiments examined this claim using letter string stimuli constructed according to the rules of […]

Interkey timing in piano performance and typing

Interkey timing in piano performance and typing Schmuckler, Mark A Abstract In typing, when the fingers executing two successive movements are on the same hand, the time between keystrokes is longer than when the fingers are on different hands. Biomechanical limitations of the hands are thought to account for this difference. The generality of this […]

Semantics turns back the clock

Word recognition and temporal order judgments: Semantics turns back the clock Jennifer A Stolz Abstract This paper examines the consequences that codes activated during reading have on activities unrelated to reading by investigating the effects of semantics on temporal order judgments. Participants judged which of two word targets appeared first. Targets appeared either synchronously, or […]

Multiple object tracking and attentional processing

Multiple object tracking and attentional processing Christopher R Sears Abstract How are attentional priorities set when multiple stimuli compete for access to the limited-capacity visual attention system? According to Pytyshyn (19 89) and Yantis and Johnson (1990), a small number of visual objects can be preattentively indexed or tagged and thereby accessed more rapidly by […]

Newborns discriminate schematic faces from scrambled faces

Newborns discriminate schematic faces from scrambled faces Megan A Easterbrook Abstract Newborn attention to, and discrimination of, facelike patterns was examined in three experiments employing 35 one- to three-day-old infants. Differential eye tracking and head turning to three moving stimuli (a schematic face, a scrambled face, and a luminance-matched blank) were measured in two of […]

Representing quantity beyond whole numbers: Some, none, and part

Representing quantity beyond whole numbers: Some, none, and part Ellen Bialystok Abstract Previous research has demonstrated how children develop the ability to use notational representations to indicate simple quantities. These studies have shown a developmental shift from the use of idiosyncratic, to analogical, to conventional, numerical notations. The present paper extends these findings by reporting […]

Contrast, spatial frequency, and luminance effects, The

age deficit on photopic counterphase flicker: Contrast, spatial frequency, and luminance effects, The Jody C Culham Donald W Kline Abstract This study evaluated the contribution of reduced contrast sensitivity and retinal illuminance to the age-related deficit on the temporal resolution of suprathreshold spatial stimuli. The discrimination of counterphase flicker was measured in optimally refracted young […]

Journeying Beyond Classical Somatosensory Cortex

Journeying Beyond Classical Somatosensory Cortex Sathian, K Abstract Visual cortical areas are involved in a variety of somatosensory tasks in the sighted, including tactile perception of two-dimensional patterns and motion, and haptic perception of three-dimensional objects. It is still unresolved whether visual imagery or modality-independent representations can better explain such cross-modal recruitment. However, these explanations […]

Effects of acute and prolonged opiate abstinence on extinction behaviour in rats

Effects of acute and prolonged opiate abstinence on extinction behaviour in rats Kim G C Hellemans Abstract We examined the role of withdrawal in relapse to drug-seeking and drug-taking by testing the effects of opiate abstinence on extinction behaviour in rats trained to self-administer heroin. Male Long-Evans rats responded for IV heroin under a heterogeneous […]
