One of the evolutionary adaptive benefits of altruism may be that it acts as an honest (reliable) signal of men's mate quality. In this study, 285 female participants were shown one of three video scenarios in which a male target took £30 out of a cash machine (ATM) and gave either a lot (£30), a little (£1), or nothing to a homeless man. The participants rated the male target on his attractiveness, their short- and long-term mate preferences towards him, and the degree to which they thought he was likely to possess various parenting qualities. The results showed that, regardless of whether the man was described as rich or poor, participants rated him as being more attractive when he donated money, but only when the donation was costly (£30). In addition, altruism was shown to be important in long-term, but not short-term mate choice, and displays of altruism were associated with positive parenting qualities. It is argued that displays of altruism act as a reliable (honest) mate signal for a potential long-term parental partner. [ABSTRACT FROM AUTHOR]

The current study investigated the support that a facility dog can provide to survivors of sexual crimes when undergoing video-recorded police interviews. In total, 13 survivors of sexual offences, who were undergoing a video-recorded interview, were provided with a facility dog for the interview process. For each case, data were collected via interviews, observations and surveys. Using a multiple case study approach, qualitative data were analysed to identify patterns, with observational and survey data used to provide further support to these outcomes. A total of four main themes emerged from the data: (1) a change in focus for the survivor, (2) a difference in the survivors' engagement, (3) the dog as a comforter to keep the survivor calm and (4) a positive environment. Overall, the findings suggest that the facility dog provided a much needed and beneficial service to survivors, helping them feel calmer and more comfortable. The dog also provided survivors with a more positive environment, allowing them to focus on the interview and communicate more openly about their experiences. The current study, therefore, presents very positive findings relating to improving survivors' perspectives of justice within the framework of kaleidoscopic justice, bridging their perceived justice gap.
