“…The second measure, referred to as preference change , takes into account any initial biases by comparing the proportion of time spent with the two objects in Trial 1 to the proportion of time spent with the two objects in Trial 2. Previous research has reported that individual rats exhibit side‐biases in behavioral tests and that rotational behavior differs between ages and sexes (e.g., Becker, Robinson, & Lorenz, 1982; Hyde & Jerussi, 1983; Schwarting & Borta, 2005). To take into account any biases that could affect the time spent with either object in Trial 1 (including individual preferences for a specific object), a side preference was calculated for both Trials 1 and 2 [(Time with right object − Time with left object)/(Total time with both objects) × 100], with a negative value representing a left‐side preference, and a positive value indicating a right‐side preference.…”

In humans, novelty-seeking behavior peaks in adolescence and is higher in males than females. Relatively, little information is available regarding age and sex differences in response to novelty in rodents. In this study, male and female Lister-hooded rats were tested at early adolescence (postnatal day, pnd, 28), mid-adolescence (pnd 40), or early adulthood (pnd 80) in a novel object recognition task (n = 12 males/females per age group). Males displayed a higher preference for the novel object than females at mid-adolescence, with no sex difference at early adolescence. Adult females interacted with the novel object more than adult males, but not when side biases were removed. Sex differences at mid-adolescence were not found in other measures, suggesting that the difference at this age was specific to situations involving choice of novelty. The results are considered in the context of age- and sex-dependent interactions between gonadal hormones and the dopamine system. © 2011 Wiley Periodicals, Inc. Dev Psychobiol 53:670–676, 2011.

“…Research in rats using the plus-maze or T-maze demonstrated asymmetries in turning direction in favor of the right/clockwise (Andrade, Alwarshetty, Sudha, & Chandra, 2001; Schwarting, & Borta, 2005). The findings in rodents have been supported by the findings of studies in fishes.…”

Reviewing the relevant literature in visual psychophysics and visual neuroscience we propose a three-stage model of directionality bias in visuospatial functioning. We call this model the ‘Perception-Action-Laterality’ (PAL) hypothesis. We analyzed the research findings for a wide range of visuospatial tasks, showing that there are two major directionality trends: clockwise versus anticlockwise. It appears these preferences are combinatorial, such that a majority of people fall in the first category demonstrating a preference for stimuli/objects arranged from left-to-right rather than from right-to-left, while people in the second category show an opposite trend. These perceptual biases can guide sensorimotor integration and action, creating two corresponding turner groups in the population. In support of PAL, we propose another model explaining the origins of the biases– how the neurogenetic factors and the cultural factors interact in a biased competition framework to determine the direction and extent of biases. This dynamic model can explain not only the two major categories of biases, but also the unbiased, unreliably biased or mildly biased cases in visuosptial functioning.

“…The data concerning spatial preference are, however, rather ambiguous even for laboratory mammals such as rats or hamsters [17,22]. Most evidence concerning motor bilateral asymmetries in laboratory mammals is from the study of paw preference in "reaching" reactions [8].…”

The crayfish, Procambarus cubensis, placed in the central area of a plus-maze preferred to go forward in about 50% of trials; they chose the right or left arm in 20.7 and 18.9% of the trials, respectively. In a T-maze, the difference between right and left directions was also insignificant. When exploring a plus-maze, the crayfish turned to 180 degrees at the end of the arms, then turned to 90 degrees going to the next arm. The mean difference between the right and left U-turns, and the right and left turns was insignificant though some animals demonstrated a left or right preference. There was a strong correlation between the direction of U-turns and following turns ensuring the clockwise or anti-clockwise movements of the crayfish. Also we examined a possible preference of the right or left claw in the feeding behavior of the crayfish. The crayfish caught a small bloodworm given from above equally with the right or left claw. The crayfish conditioned to take a bloodworm with a claw did not demonstrate any stable preference of left or right claw in the course of the experiments. The question of bilateral asymmetries within the decapod crustaceans is discussed.
