UNLABELLED This paper describes a new instrument for evaluating the experience of the stuttering disorder from the perspective of individuals who stutter. Based on the World Health Organization's International Classification of Functioning, Disability, and Health [World Health Organization (2001). The International Classification of Functioning, Disability, & Health. Geneva: World Health Organi...

We investigated the influence of processing relevant spatial information on learning a probabilistic sequence of irrelevant locations. Using the SRT design of Remillard (2003), we found that spatial perceptual learning occurs with paired but not with single targets. The pairs of targets consisted of the same stimuli, but in a different order, so that responses could have been based on the left-...

Many auditory displays use acoustic attributes such as frequency, intensity, and spectral content to represent different characteristics of multidimensional data. This study demonstrated a perceptual interaction between dynamic changes in pitch and loudness, as well as perceived asymmetries in directional acoustic change, that distorted the data relations represented in an auditory display. Thr...

A spin glass is a type of magnetic ordering that can emerge, most transparently, when a system is both frustrated and has quenched disorder. This paper will review some of the basics of such systems, and then touch on some of the experimental results that served as a guide for the theory. In exploring the theory it will focus on one particular framework, the replica approach, that has been used...

Eisemann Martin: ’Psychosocial aspects of depressive disor­ ders’. From the Department of Psychiatry, Umeå University,

This randomized trial of a family-focused preventive intervention for Mexican American middle schoolers examined internalizing, externalizing, and substance use outcomes in late adolescence, 5 years after completing the intervention. Parent-adolescent conflict was tested as a mediator of these effects. The role of parent and adolescent acculturation in these pathways was also examined. There we...

Humans share with non-human animals perceptual biases that might form the basis of complex cognitive abilities. One example comes from the principles described by the iambic-trochaic law (ITL). According to the ITL, sequences of sounds varying in duration are grouped as iambs, whereas sequences varying in intensity are grouped as trochees. These grouping biases have gained much attention becaus...

Objects that are briefly flashed around the time of saccades are mislocalized. Previously, robust interactions between saccadic perceptual distortions and stimulus contrast have been reported. It is also known that crowding depends on the contrast of the target and flankers. Here, we investigated how stimulus contrast and crowding interact with pre-saccadic perception. We asked observers to rep...

Auditory event-related potentials (AERPs) were recorded concurrently with behavioral responses to dichotic CVs in 16 young, normal, right-handed, female subjects. The results showed the expected behavioral right-ear advantage and an N105-P184 complex of significantly greater amplitude over the left temporal region than over the right. In another normal individual showing a consistent behavioral...
