Data for behavioral results and brain regions showing a time effect during pair-association retrieval.

The current data article provides behavioral and neuroimaging data for the research article "Relatedness-dependent rapid development of brain activity in anterior temporal cortex during pair-association retrieval" (Jimura et al., 2016) [1]. Behavioral performance is provided in a table. Fig. 2 of the article is based on this table. Brain regions showing time effect are provided in a table. A statistical activation map for the time effect is shown in Fig. 3C of the article.

Value of the data

Behavioral results can be used to see performance of the pair association task.

List of coordinates in standard space are used to see brain regions showing the time effect.

The data can be used for any meta-analytic purpose.

Data

Behavioral results for the performance of the pair association task are shown in Table 1. Brain regions showing significant time effect are listed in Table 2.

Experimental design, materials and methods

Group-level mean and standard errors of the mean (SEM) were calculated for behavioral performance of the pair-association task [1]. The performance was calculated for each experimental condition. Brain regions were identified showing voxel-level significant effect of time in a group analysis (P<.05, corrected for multiple comparisons across the whole brain with family-wise error rate). Coordinates are listed in the order of statistical significance level. Full descriptions are available in the article.
