While searching for objects, we combine information from multiple visual modalities. Classical theories of visual search assume that features are processed independently prior to an integration stage. Based on this, one would predict that features that are equally discriminable in single feature search should remain so in conjunction search. We test this(More)
Grasping an object rather than pointing to it enhances processing of its orientation but not its color. Apparently, visual discrimination is selectively enhanced for a behaviorally relevant feature. In two experiments we investigated the limitations and targets of this bias. Specifically, in Experiment 1 we were interested to find out whether the effect is(More)
The purpose of this study was to assess the relative contribution of personality and emotional experience to self-reported eating attitudes in a group of patients with clinically diagnosed eating disorders, a weight-reduction training group (Weight Watchers), and a control group without body weight problems. Participants in this study (N = 114) completed(More)
The purpose of the present study was to investigate a theory of planned behavior model for the prediction of physical activity in adolescent girls using a 1-yr. longitudinal design. A secondary purpose was to examine the moderating influence of intention stability and past behavior on intention-behavior relationships. Participants were 236 12- to(More)
INTRODUCTION The aim was to compare the average and the days method in exploring the compliance of children with physical activity guidelines and describe their physical activity patterns in different school day segments. METHODS Physical activity was objectively measured in 472 children aged 6-13 for one school week. Children were compliant when(More)
A common approach to visualise multidimensional data sets is to map every data dimension to a separate visual feature. It is generally assumed that such visual features can be judged independently from each other. However, we have recently shown that interactions between features do exist [Hannus et al. 2004; van den Berg et al. 2005]. In those studies, we(More)
