Figures & data
Figure 1. (a) Experiment 1 procedure. Participants carried out six trial blocks (i.e. each memory block type – colour, shape, binding – under each encoding time condition – 900, 1500 ms). (b) Experiment 3 procedure – suffix condition. Each participant carried out each memory type (colour, shape, binding) under each interference condition (control, suffix). The control condition was the same as the 900 ms condition of Experiment 1. In all experiments, stimuli were drawn from a pool of six different colours and shapes, and are not drawn to scale here. Fill effects represent different colours.
Table 1. Change sensitivity data (mean A′ scores; with standard deviations) for each condition across all three experiments.
Figure 2. Proportion correct data (±SE) from Experiment 2 sequentially presented target trials. (a) Interaction between age group and serial position. (b) Interaction between memory test type and serial position.
Figure 3. Interaction between age group and suffix condition in the Experiment 3 A′ data (±SE). (Data are collapsed across memory test type.)
Figure 4. Effect sizes (Cohen's d) for feature binding memory compared with shape memory, for the two age groups in each experiment.
