Inducing strategies to solve a mental rotation task is possible: evidence from a sex-related eye-tracking analysis.

The study of spatial skills is gaining importance due to their relevance in everyday activities and their critical role in developing competencies across various academic disciplines. The main goal of this study was to explore whether mental rotation strategies, such as the so-called holistic -rotating an entire object- and piecemeal -rotating individual parts of the object- approaches, can be induced, and whether sex differences emerge during the process of strategy induction. This objective holds a pivotal role as it could lead to the enhancement of mental rotation abilities and the development of effective interventions.

Intersaccadic drift velocity is sensitive to short-term hypobaric hypoxia.

Hypoxia, defined as decreased availability of oxygen in the body's tissues, can lead to dyspnea, rapid pulse, syncope, visual dysfunction, mental disturbances such as delirium or euphoria, and even death. It is considered to be one of the most serious hazards during flight. Thus, early and objective detection of the physiological effects of hypoxia is critical to prevent catastrophes in civil and military aviation.

Thermal sensitivity and cardiovascular reactivity to stress in healthy males.

This paper examines the association of cardiovascular reactivity with thermal thresholds (detection and unpleasantness). Heart period (HP), systolic (SBP) and diastolic (DBP) blood pressure of 42 health young males were recorded during a cardiovascular reactivity task (a videogame based upon Sidman's avoidance paradigm). Thermal sensitivity, assessing detection and unpleasantness thresholds with radiant heat in the forearm was also estimated for participants.

Pupillary dilation as an index of task demands.

To analyze how pupillary responses reflect mental effort and allocation of processing resources under several load conditions, the pupil diameter of 18 participants was recorded during an auditory digit-span recall task under three load conditions: Low (5 digits), Moderate (8 digits), and Overload (11 digits). In previous research, under all load conditions a significant linear enlargement in pupil diameter was observed as each digit was presented. Significant dilations from the end of the presentation phase to the beginning of the recall phase were also observed but only under low and moderate loads.

Differences in duration of eye fixation for conditions in a numerical stroop-effect experiment.

Durations of eye fixation were recorded for a numerical Stroop effect experiment. Participants (6 men, 19 women; M age=22 yr.) reported the number of characters present in sequences of variable length (2 to 5 characters) while attempting to ignore the identity of the character.
