The Influence Of Schizotypal Traits On Active Display Recognition, Lucinda V. Rohde
The Influence Of Schizotypal Traits On Active Display Recognition, Lucinda V. Rohde

Accurate recognition of changes in scene layout is necessary to function in everyday life. Self-motion sensitivity, comprised of efference copy and afferent signals, is employed to respond to these changes, however little is known about how these signals may influence active display recognition. Previous spatial perception experimentation has shown that individuals with high schizotypal traits perform differently than those with low schizotypal traits while estimating walked distance in non-visual walking and imagined walking tasks (Rohde & Yamamoto, 2013). It is postulated that this result could be attributed to a presumable dysfunction of efference copy associated with schizotypy. It was hypothesized …

McLennan and Luce (2005) found no significant cost associated with changing which talker produced a particular word from the first block of trials to the second (no talker effects) when participants responded relatively quickly (easy lexical decision), and that talker effects emerged when participants responded relatively slowly (hard lexical decision). In a lexical decision task, participants hear words and nonwords and reaction times to correct responses are measured. In the current study, we examined whether social factors would lead to talker effects in an easy lexical decision task. In Experiment 1, participants were told that they have a chance to …
Perceived Difficulty In A Fitts Task, Suzanne M. Grilli
Perceived Difficulty In A Fitts Task, Suzanne M. Grilli

This study provided a detailed investigation of perceived difficulty (PD) in a Fitts task. The Fitts task has been used to study Fitts's law, which shows that movement time (MT) is related to the information constraints of the movement (Fitts's Index of Difficulty, ID) such that there is a positive, linear relationship between MT and ID and MTs are similar when the scale of the movement requirements vary but ID is equal (scale invariance). According to Fitts's law, Fitts's ID provides an index of objective difficulty does Fitts's ID also provide an index of subjective difficulty? The main goal of …
