A new approach to problems of multiple significance testing was presented in Benjamini and Hochberg (1995), which calls for controlling the expected ratio of the number of erroneous rejections to the number of rejections–the False Discovery Rate (FDR). The procedure given there was shown to control the FDR for independent test statistics. When some of the hypotheses are in fact false, that procedure is too conservative. We present here an adaptive procedure, where the number of true null hypotheses is estimated first as in Hochberg and Benjamini (1990), and this estimate is used in the procedure of Benjamini and Hochberg (1995). The result is still a simple stepwise procedure, to which we also give a graphical companion. The new procedure is used in several examples drawn from educational and behavioral studies, addressing problems in multi-center studies, subset analysis and meta-analysis. The examples vary in the number of hypotheses tested, and the implication of the new procedure on the conclusions. In a large simulation study of independent test statistics the adaptive procedure is shown to control the FDR and have substantially better power than the previously suggested FDR controlling method, which by itself is more powerful than the traditional family wise error-rate controlling methods. In cases where most of the tested hypotheses are far from being true there is hardly any penalty due to the simultaneous testing of many hypotheses.

The Difference

Background. Here we report on a meta-analysis of the attentional blink (AB) research focussed on specific reading impairment, commonly referred to as developmental dyslexia. The AB effect relates to a limitation in the allocation of attention over time and examined in a dual-target rapid serial visual presentation paradigm. When the second target appears in close temporal proximity to the first target, the second target is reported less accurately. Method. A Web of Science search with terms 'dyslexia attentional blink' returned 13 AB experiments (11 papers) conducted with developmental dyslexia (9 were included in this meta-analysis). The main pattern of performance was lower overall accuracy in groups of individuals with dyslexia relative to typically reading peers. That is, a between-group main effect. This meta-analysis examined the size of the between-group effect in relation to physical presentation characteristics, which differed between and within experiments. Results. Four noteworthy variables were related to the between group effect-size; fixation duration (positive relationship, R2 = .89, p <.01, n = 6), maximum temporal position of T2 (negative relationship, R2 = .46, p <.05, n = 9), the difference between the minimum and maximum temporal position of T2 (negative relationship, R2 = .53, p <.05, n = 9), and the stimulus onset asynchrony (negative relationship, R2 = .46, p <.05, n = 9). Discussion. These are discussed with respect to the preparation of task-set, temporal orienting, and speed of processing, recommending these as considerations for future research.
