In the present cohort study we have the ability to carry out the transmission-disequilibrium test (TDT), which is a simultaneous test for linkage and association.
Third (C, D), two tools the functional one that had been used for the training and a nonfunctional one that had the plate of the tool raised by wire so that food could not be retrieved were given to the degus in a simultaneous choice test to see which tool they selected first.
Additionally, Joyce et al. (2009) found a significant female preference for large males compared to small males in a simultaneous choice test in the solitary parasitoid Cotesia marginiventris Cresson (Braconidae); large and small males were equally likely to attempt copulation first but females more frequently accepted large males.
The recent demonstration that honeybee nurse bees, infected with the microsporidian gut parasite Nosema ceranae, show different preferences for various types of honeys in a simultaneous choice test, preferring honeys with a higher antibiotic activity (Gherman et al., 2014), suggests that such behaviours may be widespread in social pollinators.
In fact, it is difficult for the method of Berry et al. to calculate the confidence intervals of certain complex statistics involved in joint simultaneous testing, such as the joint positive predictive value (PPV JE ), joint sensitivity (Se JE ), and joint specificity (Sp JE ), which are important in evaluating model fitting in this type of study.
A conventional DSWHS with the same dimensions and geometry than the PCS was installed to compare their performance in simultaneous tests.
The biomicrosystem carries out 98 in situ different simultaneous tests without specialized equipment or personnel.
The first stage is a joint simultaneous testing consisting of two dependent binary tests.
However, many of these findings have been recently challenged by a study of Minini and Jeffery [146], who concluded that rats, when tested in a simultaneous (i.e., a two-alternative forced-choice) discrimination task, do not spontaneously rely on a shape-based recognition strategy, at least when other lower-level visual cues are available to successfully accomplish the task.
