When smiling back helps and scowling back hurts: individual differences in emotional mimicry are associated with self-reported interaction quality during conflict interactions

Motivation and Emotion - Conflicts or disagreements during which negative, antagonistic emotions are expressed are perceived as uncomfortable. By contrast, disagreements accompanied by positive,...     

Human listeners provide insights into echo features used by dolphins (Tursiops truncatus) to discriminate among objects

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.     

Can defendants with mental retardation successfully fake their performance on a test of competence to stand trial?

The purpose of this study was to determine whether criminal defendants with mental retardation can feign poor performance on a test of competence to stand trial. Four groups of adjudicated criminal defendants were given a test of competence to stand trial. In the experimental condition, defendants with mental retardation (MR) and mentally typical defendants (non-MR) were given instructions to fake their performance on the test. In the control, MR defendants and non-MR defendants took the test under standard conditions. The results indicated that both the MR and non-MR fakers scored significantly lower than the MR and non-MR controls. There was no significant difference in the scores of the MR and non-MR fakers. The results suggest that defendants with mental retardation may be able to successfully fake their performance in certain circumstances. Implications of these findings are discussed.     

The Children's Automatic Thoughts Scale in a clinical sample: psychometric properties and clinical utility

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.     

Interlinking physical beliefs: children's bias towards logical congruence

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.     

Father-infant interaction, paternal ideas about early child care, and their consequences for the development of children's self-recognition

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.     

The association between life events and suicide intent in self-poisoners with and without a history of deliberate self-harm: a preliminary study

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.     

A threat in the computer: the race implicit association test as a stereotype threat experience

Three experiments test whether the threat of appearing racist leads White participants to perform worse on the race Implicit Association Test (IAT) and whether self-affirmation can protect from this threat. Experiments 1 and 2 suggest that White participants show a stereotype threat effect when completing the race IAT, leading to stronger pro-White scores when the test is believed to be diagnostic of racism. This effect increases for domain-identified (highly motivated to control prejudice) participants (Experiment 2). In Experiment 3, self-affirmation inoculates participants against stereotype threat while taking the race IAT. These findings have methodological implications for use of the race IAT and theoretical implications concerning the malleability of automatic prejudice and the potential interpersonal effects of the fear of appearing racist.
