Because of coding errors in the data collected from Spain (Varnum et al., 2019), the original values recorded for breakup concern, mate retention, and kin care (family) were not accurate. Consequently, some of the effect sizes calculated from those data and reported in the article are incorrect. On page 177, left column, the sentence beginning “Furthermore,” near the bottom of the page, should read as follows: “Furthermore, women scored significantly higher on mate retention (for the Neel et al. data, d = 0.41; for the Varnum et al. data, d = 0.23), kin care (family; for the Neel et al. data, d = 0.47; for the Varnum et al. data, d = 0.32), and kin care (children; for the Neel et al. data, d = 0.28; for the Varnum et al. data, d = 0.18) than did men.” Also on page 177, right column, the last sentence in the section should read as follows: “The effect sizes were indeed quite large for paired comparisons between mate seeking and kin care (family; for the Neel et al. data, d = 1.78; for the Varnum et al. data, d = 1.62) and between mate seeking and kin care (children; for the Neel et al. data, d = 3.21; for the Varnum et al. data, d = 1.67).”
These errors require Figures 3, 4, and 6 to be corrected as well. The corrected figures appear below. The overall findings, inferences, and conclusions of the article were not substantially affected by these errors.
Fundamental Social Motive Inventory results. The plot in (a) shows results from an Amazon Mechanical Turk sample (N = 1,560; Neel et al., 2016). The plot in (b) shows results from ongoing global data collection from 27 countries (N = 7,296; Varnum, Kenrick, Pick, & Ko, 2019) aggregated across all countries. The plots in (c) show the same data broken down by country. Breakup-concern and mate- retention questions were asked only of participants in relationships. Kin-care (children) questions were asked only of participants who had children. For the box-and-whiskers plots, the horizontal bar and circle within each box represent the median and mean, respectively. The top and bottom of the box represent the interquartile range, and the ends of the whiskers represent the maximum (top) and minimum (bottom) values. The dashed line indicates the scale midpoint. Red plots show mate-seeking and breakup-concern goals, and blue plots show goals linked to long-term familial bonds. SPO = self-protection; DIS = disease avoidance; AFG = affiliation (group); AFI = affiliation (independence); AFX = affiliation (exclusion concern); STA = status; MAT = mate seeking; MRB = breakup concern; MRT = mate retention; KCF = kin care (family); and KCC = kin care (children).
Box-and-whiskers plots of self-rated motivations related to mate seeking and breakup concern (red) and familial bonds (blue), separately for female (yellow shading) and male (no shading) participants. The horizontal bar and circle within each box represent the median and mean, respectively. The top and bottom of the box represent the interquartile range, and the ends of the whiskers represent the maximum (top) and minimum (bottom) values. The dashed line indicates the scale midpoint. Data for (a) are from Neel, Kenrick, White, and Neuberg’s (2016) focal study and data for (b) are from an ongoing global data collection from 27 countries (Varnum, Kenrick, Pick, & Ko, 2019).
Fundamental Social Motive Inventory results from all participants who provided data depicted in Figures 1, 3, and 5, presented separately for participants who were in a long-term relationship (green shading; n = 6,869) and participants who were not (no shading; n = 5,177). Breakup-concern and mate-retention items were not relevant to individuals not in relationships, and such individuals were asked not to complete them. The vertical bar and circle within each box represent the median and mean, respectively. The left and right sides of the box represent the interquartile range, and the ends of the whiskers represent the maximum (right) and minimum (left) values. The dashed line indicates the scale midpoint. Red plots show mate-seeking and breakup-concern goals, and blue plots show goals linked to long-term familial bonds.
