Look, no hands: A perceptual task shows that number magnitude induces shifts of attention

Look, no hands: a perceptual task shows that number magnitude induces shifts of attention.

The mental representation of numbers along a line oriented left to right affects spatial cognition, facilitating responses in the ipsilateral hemispace (the spatial-numerical association of response codes [SNARC] effect). We investigated whether the number/space association is the result of an attentional shift or response selection. Previous research has often introduced covert left/right resp...

Look 'Ma, No Hands: Part-Task Training of Perceptual-Cognitive Skills to Accelerate Psychomotor Expertise

Emerging sports science research reveals that expert performance in rapid and reactive skills such as baseball batting, return-of-serve in tennis, and goalie play in hockey and soccer is based on superior perceptual-cognitive skills that allow a competitor to perceive predictive cues in an opponent's actions. Situational decision-making, such as the pass/dribble/shoot decision of soccer or bask...

"Look Ma, No Hands!" A Parameter-Free Topic Model

It has always been a burden to the users of statistical topic models to predetermine the right number of topics, which is a key parameter of most topic models. Conventionally, automatic selection of this parameter is done through either statistical model selection (e.g., cross-validation, AIC, or BIC) or Bayesian nonparametric models (e.g., hierarchical Dirichlet process). These methods either ...

Look Ma , No Hands ! Aspects of Autonomous Vehicle Control

Perceptual reversals need no prompting by attention.

Many ambiguous patterns elicit spontaneous alternations of phenomenal appearance. Attention is known to influence these phenomenal reversals, as do several other factors. We asked whether a shift of attention individually prompts each reversal of phenomenal appearance. By combining intermittent presentation with a proven method of attention control, we monitored phenomenal alternations in the c...
