Young children interpret number gestures differently than nonsymbolic sets

Researchers have long been interested in the origins of humans’ understanding of symbolic number, focusing primarily on how children learn the meanings of number words (e.g., “one”, “two”, etc.). However, recent evidence indicates that children learn the meanings of number gestures before learning number words. In the present set of experiments, we ask whether children's early knowledge of number gestures resembles their knowledge of nonsymbolic number. In four experiments, we show that preschool children (n = 139 in total; age M = 4.14 years, SD = 0.71, range = 2.75–6.20) do not view number gestures in the same the way that they view nonsymbolic representations of quantity (i.e., arrays of shapes), which opens the door for the possibility that young children view number gestures as symbolic, as adults and older children do.

Highlights

• Children were more accurate when enumerating briefly-presented number gestures than arrays of shapes, with a shallower decline in accuracy as quantities increased.
• We replicated this finding with arrays of shapes that were organized into neat, dice-like configurations (compared to the random configurations used in Experiment 1).
• The advantage in enumerating briefly-presented number gestures was evident before children had learned the cardinal principle.
• When gestures were digitally altered to pit handshape configuration against number of fingers extended, children overwhelmingly based their responses on handshape configuration.

     

The Impact of Participating in Suicide Research Online

The impact of participation in online mixed‐methods suicide research was investigated. Participants, who described feeling suicidal, completed an 18‐item questionnaire before and after taking part (n = 103), and answered open‐ended questions about participation (n = 97). Overall, participation reduced negative experiences and had no effect on positive experiences. Feelings of calm increased, but participants felt less supported. Some participants did experience distress, but some also reported this distress to be manageable. Anonymously sharing experiences of suicidality was viewed as important, had therapeutic benefits, and engendered hopes for recovery. The findings suggest a need to ensure vulnerable participants in online studies are well supported while protecting their anonymity.
