Task and Dimension Switching Data Set
<p>This data set contains the data of 8 experiments concerned with the question how multi-component task sets are organised. Four different views on task set organisation were tested in these experiments. Experiments 1-4 were used in Vandierendonck, A., Christiaens, E., & Liefooghe, B. (2008). On the representation of task information in task switching: Evidence from task and dimension switching. <em>Memory & Cognition, 36</em>(7), 1248-1261. doi: 10.3758/mc.36.7.1248. The entire data set was used for a test of the utility of integrated measures of speed and accuracy. This is currently a submitted paper: Vandierendonck, A. Further tests of the utility of integrated speed-accuracy measures in task switching. Journal of Cognition.</p>
Processing differences in Explicit and Transition Cues in Task Switching
<p>This dataset consists of 5 experiments that compare cue and task processing performance in task switching with explicit and transition cues. Experiments 1-3 have been published in Van Loy, Liefooghe and Vandierendonck (2010). The entire data set is used in a study on the utility of integrated measures of speed and accuracy (Vandierendonck, submitted).</p>

Data from: Histone acetyltransferases and external demands influence task switching in Temnothorax ants
<p><span>In social hymenopterans, workers specialize on different tasks. Whether a worker nurses the brood or forages is influenced by the responsiveness for task-related cues which in turn is determined by gene expression. Task choice is dynamic and changes throughout a worker's life, e.g. with age or in response to increased demands for certain tasks. Behavioral switches require the ability to adjust gene expression but the mechanisms regulating such transcriptional adaptations remain elusive. We investigated the role of histone acetylation in task specialization and behavioral flexibility in <em>Temnothorax longispinosus</em> ants. By inhibiting p300/CBP histone acetyltransferases (HAT) and manipulating colony composition, we found that HAT inhibition impairs the ability of older workers to switch to brood care. Yet, HAT inhibition increased the ability of young workers to accelerate their behavioral development and switch to foraging. Our data suggest that HAT in combination with social signals indicating task demands play an important role in modulating behavior. Elevated HAT activity may contribute to keeping young brood carers from leaving the nest, where they would be exposed to high mortality. These findings shed light on the epigenetic processes underlying behavioral flexibility in animals and provide insight into the mechanisms of task specialization in social insects.</span></p>

Data from: Task-switching is associated with temporal delays in Temnothorax rugatulus ants
The major evolutionary transitions often result in reorganization of biological systems, and a component of such reorganization is that individuals within the system specialize on performing certain tasks, resulting in a division of labor. Although the traditional benefit of division of labor is thought to be a gain in work efficiency, one alternative benefit of specialization is avoiding temporal delays associated with switching tasks. While models have demonstrated that costs of task switching can drive the evolution of division of labor, little empirical support exists for this hypothesis. We tested whether there were task-switching costs in Temnothorax rugatulus. We recorded the behavior of every individual in 44 colonies and used this dataset to identify each instance where an individual performed a task, spent time in the interval (i.e., inactive, wandering inside, and self-grooming), and then performed a task again. We compared the interval time where an individual switched task type between that first and second bout of work to instances where an individual performed the same type of work in both bouts. In certain cases, we find that the interval time was significantly shorter if individuals repeated the same task. We find this time cost for switching to a new behavior in all active worker groups, that is, independently of worker specialization. These results suggest that task-switching costs may select for behavioral specialization.
