The aim of the current research was to identify conditions under which choice blindness in facial recognition decisions occurs. In five experiments, participants watched four mock‐crime videos and made choices that were either evaluative (Experiment 1) or absolute in nature (Experiments 2a–c and 3). When participants were subsequently asked to motivate their choice, they were sometimes presented with choices they had not made. For evaluative decisions, concurrent (27%) and retrospective blindness rates (21%) were relatively low compared with previous studies. For absolute decisions, choice‐blindness rates varied, depending on when exposure to the manipulated outcome took place (immediate: concurrent 32–35%, retrospective 0–6% [Experiments 2a–c]; 48 hours' delay: concurrent 68%, retrospective 39% [Experiment 3]). We argue that blindness for facial recognition decisions is more likely for evaluative decisions and for longer intervals between decision and manipulation and also for conditions of increased task complexity, which we interpret in terms of ambiguity.

Researchers in comparative psychology often use different food rewards in their studies, with food values defined by a pre-experimental preference test. While this technique rank orders food values, it provides limited information about value differences because preferences may reflect not only value differences, but also the degree to which one good may “substitute” for another (e.g., one food may substitute well for another food, but neither substitutes well for water). We propose scaling the value of food pairs by a third food that is less substitutable for either food offered in preference tests (cross-modal scaling). Here, Cebus monkeys chose between four pairwise alternatives: fruits A versus B; cereal amount X versus fruit A and cereal amount Y versus fruit B where X and Y were adjusted to produce indifference between each cereal amount and each fruit; and cereal amounts X versus Y. When choice was between perfect substitutes (different cereal amounts), preferences were nearly absolute; so too when choice was between close substitutes (fruits); however, when choice was between fruits and cereal amounts, preferences were more modest and less likely due to substitutability. These results suggest that scaling between-good value differences in terms of a third, less-substitutable good may be better than simple preference tests in defining between-good value differences.  相似文献

In a previous study (Péron et al. in Anim Cogn, doi:10.1007/s10071-012.05640, 2012), Grey parrots, working in dyads, took turns choosing one of four differently coloured cups with differing outcomes: empty (null, non-rewarding), selfish (keeping reward for oneself), share (sharing a divisible reward), or giving (donating reward to other). When the dyads involved three humans with different specific intentions (selfish, giving, or copying the bird’s behaviour), birds’ responses only tended towards consistency with human behaviour. Our dominant bird was willing to share a reward with a human who was willing to give up her reward, was selfish with the selfish human, and tended towards sharing with the copycat human; our subordinate bird tended slightly towards increased sharing with the generous human and selfishness with the selfish human, but did not clearly mirror the behaviour of the copycat. We theorized that the birds’ inability to understand the copycat condition fully—that they could potentially maximize reward by choosing to share—was a consequence of their viewing the copycat’s behaviour as erratic compared with the consistently selfish or giving humans and thus not realizing that they were indeed being mirrored. We suggested that copycat trials subsequently be performed as a separate experiment, without being contrasted with trials in which humans acted consistently, in order to determine if results might have differed. We have now performed that experiment, and shown that at least one Grey parrot—our dominant—responded in a manner suggesting that he deduced the appropriate contingencies.  相似文献

Factors influencing the abilities of different animals to use cooperative social cues from humans are still unclear, in spite of long-standing interest in the topic. One of the few species that have been found successful at using human pointing is the African elephant (Loxodonta africana); despite few opportunities for learning about pointing, elephants follow a pointing gesture in an object-choice task, even when the pointing signal and experimenter’s body position are in conflict, and when the gesture itself is visually subtle. Here, we show that the success of captive African elephants at using human pointing is not restricted to situations where the pointing signal is sustained until the time of choice: elephants followed human pointing even when the pointing gesture was withdrawn before they had responded to it. Furthermore, elephants rapidly generalised their response to a type of social cue they were unlikely to have seen before: pointing with the foot. However, unlike young children, they showed no sign of evaluating the ‘rationality’ of this novel pointing gesture according to its visual context: that is, whether the experimenter’s hands were occupied or not.  相似文献

Given worldwide prevalence of low-stakes testing for monitoring educational quality and students’ progress through school (e.g., Trends in International Mathematics and Science Study, Program for International Student Assessment), interpretability of resulting test scores is of global concern. The nonconsequential nature of low-stakes tests can undermine students’ test-taking motivation, artificially deflating performance and thus jeopardizing validity of test-based inferences, whether they pertain to programs, institutions, or nations (Eklöf, 2007, 2010; Stanat & Lüdtke, 2013; Wise & DeMars, 2005). Moreover, students in countries such as the United States, where academic progress over the course of K–12 (kindergarten through Grade 12) is systematically assessed, are likely to develop antagonistic attitudes toward low-stakes testing by the time they enter college. The relationship between such attitudes, test-taking motivation, and performance on a low-stakes university accountability test was modeled via path analysis. Results indicated the effects of attitudes were indirect (via test-taking motivation) and minimal, suggesting the influence of attitudes on test performance is negligible, further supporting the validity of inferences made from such low-stakes tests. Implications for international assessment are discussed.  相似文献

This study focused on the effects of family type, family relationships and socialization on alcohol consumption and delinquent behaviour among Flemish adolescents. Data came from the second round of the Leuven Adolescents and Families Study and were collected in 2010 by paper-and-pencil questionnaires in 10 different secondary schools (N = 1,688). The results show that children living in non-intact families are more likely to be delinquent and to drink alcohol at an age it is not legally allowed (below 16 years old). High delinquent behaviour is found among boys in single parent families and among girls in stepfamilies. For alcohol use the reverse is true. A good relationship with the same-sex parent is negatively associated with delinquency. High interparental conflict increases delinquency for boys and alcohol use for girls. Parental role models are highly important, since drinking behaviour of parents, and especially the same-sex parent, are positively associated with externalising problems of children.  相似文献

The significant role of psychosocial factors in the management of type 1 diabetes in youth has been well documented. The International Society for Pediatric and Adolescent Diabetes (ISPAD) therefore published the Clinical Practice Consensus Guidelines for psychological care of young patients. However, it is unclear if and how these guidelines are being implemented. A questionnaire was created to assess implementation of the guidelines and directed to physicians through the ISPAD listserve via a web-based survey. One hundred fifty-five participants from 47 countries completed the survey. Ninety-six percent of respondents reported that they work in a team with other professionals, and 95 % of teams discuss psychological difficulties associated with diabetes management. Seventy-two percent of respondents reported having “easy access” to a mental health specialist (MHS). In 56 % of practice settings, the MHS is considered to be part of the team; 43 % participate in routine clinic visits and 26 % see all patients. Seventy percent screen for psychological problems and 57 % assess family functioning. Psychosocial or behavioral interventions addressing psychosocial and regimen adherence difficulties are offered by 79 % of teams. Psychological care is available for many children with diabetes worldwide. Yet, nearly 30 % of teams do not have access to a MHS. More training in the recognition of psychosocial problems and counseling skills is warranted. More advocacy is needed to increase availability and utilization of psychological services in routine diabetes care.  相似文献

Maternal guilt     
The recent emphasis on humans as cooperative breeders invites new research on human family dynamics. In this paper we look at maternal guilt as a consequence of conditional maternal investment. Solicited texts written by Finnish mothers with under school-aged children in 2007 (n = 63) described maternal emotions perceived as difficult and forbidden. Content analysis of guilt-inducing situations showed that guilt arose from diverging interest and negotiations between the mother and child (i.e., classic parent- offspring conflict). Also cultural expectations of extensive and perpetual high-quality maternal investment or the "motherhood myth" induced guilt in mothers. We argue that guilt plays an important role in maternal-investment regulation. Maternal guilt is predicted to vary with social and cultural context but also to show universal characteristics due to parent-offspring conflict and allomaternal manipulation. Results are preliminary and intended to stimulate research into the mechanisms, gender differences and cultural variations of guilt and other social emotions in human parenting.  相似文献

Brain activation associated with anhedonic depression and co-occurring anxious arousal and anxious apprehension was measured by fMRI during performance of an emotion word Stroop task. Consistent with EEG findings, depression was associated with rightward frontal lateralization in the dorsolateral prefrontal cortex (DLPFC), but only when anxious arousal was elevated and anxious apprehension was low. Activity in the right inferior frontal gyrus (IFG) was also reduced for depression under the same conditions. In contrast, depression was associated with more activity in the anterior cingulate cortex (dorsal ACC and rostral ACC) and the bilateral amygdala. Results imply that depression, particularly when accompanied by anxious arousal, may result in a failure to implement top-down processing by appropriate brain regions (left DLPFC, right IFG) due to increased activation in regions associated with responding to emotionally salient information (right DLPFC, amygdala).  相似文献
