Echolocating bottlenose dolphins (Tursiops truncatus) discriminate between objects on the basis of the echoes reflected by the objects. However, it is not clear which echo features are important for object discrimination. To gain insight into the salient features, the authors had a dolphin perform a match-to-sample task and then presented human listeners with echoes from the same objects used in the dolphin's task. In 2 experiments, human listeners performed as well or better than the dolphin at discriminating objects, and they reported the salient acoustic cues. The error patterns of the humans and the dolphin were compared to determine which acoustic features were likely to have been used by the dolphin. The results indicate that the dolphin did not appear to use overall echo amplitude, but that it attended to the pattern of changes in the echoes across different object orientations. Human listeners can quickly identify salient combinations of echo features that permit object discrimination, which can be used to generate hypotheses that can be tested using dolphins as subjects. 相似文献

The associations between life events in the 12 months preceding an episode of self-poisoning resulting in hospital attendance (the index episode), and the suicide intent of this episode were compared in individuals for whom the index episode was their first, episode and in individuals in whom it was a recurrence of DSH. Results indicated a significant interaction between independent life events, repetition status, and gender in the prediction of suicide intent, the association between life events and intent being moderated by repetition status in women only. The results provide preliminary evidence to suggest the presence of a suicidal process in women, in which the impact of negative life events on suicide intent diminishes across episodes. 相似文献

In this longitudinal study, the authors addressed intracultural variation on fathers' interactions with their 3-month-old infants, their ideas about parental care, and the timing of their children's self-recognition at the age of 18-20 months. Participants were 24 middle-class German fathers and their firstborn children. Two behavioral clusters emerged: a more proximal parenting style with extensive body contact and a more distal parenting style with extensive object stimulation. Fathers in the distal cluster had significantly more education than did fathers in the proximal cluster. Children who had experienced more distal parenting were more likely to recognize themselves in a mirror than were children with more proximal parenting. The authors discuss the results with respect to fathers' influence on child development and patterns of intracultural variation. 相似文献

The aim of this study was to examine the psychometric properties and clinical utility of the Children's Automatic Thoughts Scale (CATS; Schniering, C. A., & Rapee, R. M. (2002). Development and validation of a measure of children's automatic thoughts: The Children's Automatic Thoughts Scale. Behaviour Research and Therapy, 40, 1091-1109) in a large sample of anxious youth. The participants were 891 referred children and adolescents. Participants completed the CATS and a wide range of symptom measures, and were assessed via a structured diagnostic interview. Previous community-based psychometric properties were confirmed. The scale was highly sensitive to treatment change, and showed evidence of cognitive specificity with reductions in threat and failure beliefs, but not in hostility beliefs following treatment. The CATS demonstrated good convergent validity with related anxiety and depression scales, and moderate discriminant validity was found across anxious, anxious-depressed and anxious-oppositional groups. Implications for the assessment of child anxiety, and difficulties around children "faking good" on anxiety measures are discussed. 相似文献

Young children's na?ve beliefs about physics are commonly studied as isolated pieces of knowledge. The current paper takes a different approach. It asks whether preschoolers interlink individual beliefs into larger configurations or Gestalts. Such Gestalts bring together knowledge such as how an object's mass relates to its sinking speed, how an object's volume relates to its sinking speed, and how mass and volume are correlated. The particular form of organization explored here is referred to as logical congruence, the logical correspondence in directions among three physical relations. Are children's guesses about one physical relation congruent with their beliefs about the other two relations? And can they learn a congruent set of relations more readily than an incongruent set? Two different physical domains were explored, one in which children commonly hold pre-existing beliefs, and one in which they are likely to lack such beliefs. The results in both domains show a strong bias towards congruent knowledge configurations in young children. These findings may explain children's difficulties learning inherently incongruous concepts such as density. 相似文献

This essay acknowledges the seminal contribution of the founders of attachment theory and research as a paradigm shift in
understanding the importance of the socioemotional foundation of developmental processes. However, it is surprising that attachment
theory has been treated as a closed system by its students with remarkable resistance to change and further development of
theory and methodology. Especially three dimensions are identified that would help to advance attachment theory as a valid
conception also for the future. The context specificity of evolutionary theorizing, the different socialization goals and
parenting strategies across cultures and the new insights in infant development need to be taken into consideration in order
to develop a valid theory of socioemotional development as the culturally informed solution of universal developmental tasks.

Obtaining a job as a college graduate is partly dependent on interview performance. We used a multiple baseline design across skills to evaluate the effects of behavioral skills training with self‐evaluation for five college students. Training effects were evaluated using simulated interviews as baseline and posttraining assessments. All participants acquired targeted skills, but we observed some individual differences. Participants were satisfied with training outcomes and rated the procedures as acceptable. Furthermore, ratings from university staff who provide interview training indicated that training improved performance across several skills for the majority of participants. 相似文献

As public awareness of implicit bias has grown in recent years, studies have raised important new questions about the nature of implicit bias effects. First, implicit biases are widespread and robust on average, yet are unstable across a few weeks. Second, young children display implicit biases indistinguishable from those of adults, which suggests to many that implicit biases are learned early. Yet, if implicit biases are unstable over weeks, how can they be stable for decades? Third, meta-analyses suggest that individual differences in implicit bias are associated weakly, although significantly, with individual differences in behavioral outcomes. Yet, studies of aggregate levels of implicit bias (i.e., countries, states, counties) are strongly associated with aggregate levels of disparities and discrimination. These puzzles are difficult to reconcile with traditional views, which treat implicit bias as an early-learned attitude that drives discrimination among individuals who are high in bias. We propose an alternative view of implicit bias, rooted in concept accessibility. Concept accessibility can, in principle, vary both chronically and situationally. The empirical evidence, however, suggests that most of the systematic variance in implicit bias is situational. Akin to the “wisdom of crowds” effect, implicit bias may emerge as the aggregate effect of individual fluctuations in concept accessibility that are ephemeral and context-dependent. This bias of crowds theory treats implicit bias tests as measures of situations more than persons. We show how the theory can resolve the puzzles posed and generate new insights into how and why implicit bias propagates inequalities. 相似文献
