Inducing blindsight in normal observers.

We attempted to induce blindsight in normal observers, in an effort to replicate and extend the findings of Kolb and Braun (1995). In that demonstration, observers were able to localize a target in the absence of visual awareness, indicated by the lack ...

Sequential modulations of stimulus-response correspondence effects depend on awareness of response conflict.

In two experiments, sequential modulations of prime-target correspondence effects were investigated in a metacontrast paradigm. Primes were either unmasked and thus consciously discriminable, or entirely masked and thus indiscriminable. Mirroring similar ...

Analysis of group differences in processing speed: Brinley plots, Q-Q plots, and other conspiracies.

Researchers in a growing number of areas (including cognitive development, aging, and neuropsychology) use Brinley plots to compare the processing speed of different groups. Ratcliff, Spieler, and McKoon (2000) argued that a Brinley plot is a ...

The effect of feature frequency on short-term recognition memory.

We report two experiments using Sternbergs (1969) multitrial recognition-memory paradigm. We used colored shapes as stimuli and manipulated the frequency of the shapes (but not of the colors) across trials. For lures containing an extralist shape (i.e., ...

A context-dependent representation model for explaining text repetition effects.

The purpose of this article is to review abstract and episodic models of text repetition effects, describe the research supporting these types of models, and propose a new model called the context-dependent representation model, which can explain both ...

Effect of ball size on player reaction and racket acceleration during the tennis volley.

The purpose of this study was to examine the effect of ball size on reaction time (from ball projection to initial racket movement), movement time (from ball projection to ball-racket impact), mean rectified acceleration and vibration frequency of the ...

Comparison of thermal threshold tests to assess small nerve fiber function: limits vs. levels.

OBJECTIVE: The method of limits (MLI) and the method of levels (MLE) are psychophysical stimulus procedures most commonly applied to quantify warm and cold sensation thresholds in humans. This paper evaluates basic methodological properties of both ...

Exaggerated auditory startle responses in multiple system atrophy: a comparative study of parkinson and cerebellar subtypes.

OBJECTIVE: Auditory startle responses (ASRs) have recently been reported to be exaggerated in cranial and peripheral nerve supplied muscles of patients with multiple system atrophy (MSA). ASRs displayed increased probability, amplitude and duration, ...

A transient dominance of theta event-related brain potential component characterizes stimulus processing in an auditory oddball task.

OBJECTIVE: Following external stimulation, electroencephalographic (EEG) responses from different frequency bands occur simultaneously, but little is known about whether and how concurrent multi-frequency responses depend on each other during stimulus ...

Event-related slow-wave activity in two subtypes of attention-deficit/hyperactivity disorder.

OBJECTIVE: Previous time-frequency studies have indicated that event-related low-frequency activity has important effects on component topography and developmental effects in auditory event-related potentials (ERPs) of children and adolescents. This ...
