Simulating social interaction to address deficits of autistic spectrum disorder in children.

Autistic spectrum disorder (ASD) is diagnosed on the basis of impairment in reciprocal social interaction and language, and rigidity of behavior. This brief paper describes the development of an experimental intervention for preschool children newly diagnosed with ASD. The rationale for this intervention is the hypothesis that failure to attend to social cues in very early life, of itself, may bear a large share of responsibility for core social and communicative deficits. The intervention, therefore, uses eye-tracking to monitor and trigger rewards for attention to facial expression and direction of gaze.

Analogical reasoning in a capuchin monkey (Cebus apella)

Previous evidence has suggested that analogical reasoning (recognizing similarities among object relations when the objects themselves are dissimilar) is limited to humans and apes. This study investigated whether capuchin monkeys (Cebus apella) can use analogical reasoning to solve a 3-dimensional search task. The task involved hiding a food item under 1 of 2 or 3 plastic cups of different sizes and then allowing subjects to search for food hidden under the cup of analogous size in their own set of cups. Four monkeys were exposed to a series of relational matching tasks. If subjects reached criterion on these tasks, they were exposed to relational transfer tasks involving novel stimuli. Three of the monkeys failed to reach criterion on the basic relational matching tasks and therefore were not tested further. One monkey, however, revealed above-chance performance on a series of transfer tasks with 3 novel stimuli. This evidence suggests that contrary to previous arguments, a member of a New World monkey species can solve an analogical problem.     

Move it! Visual feedback enhances validity of preferential looking as a measure of individual differences in vocabulary in toddlers

Forty toddlers aged 20 to 24 months were presented with 32 pairs of images with the auditory stimulus Look followed by the name of the target image (e.g. Look . . . tree) in an intermodal preferential looking (IPL) paradigm. The same series of 16 items was presented first with one image as target and then with the other member of the pair as target. Half the children were given feedback, in the form of movement of the target image at the end of the trial, while the other half were presented with static images. IPL performance was quantified in terms of number of words showing at least 15% increase in proportion of looking time in the post-naming interval. Looking preference for the named item was correlated with parental report of vocabulary, this effect being stronger for those receiving feedback. The correlation with parental report of vocabulary comprehension was .65 for those receiving feedback, but only .37 for those with no feedback. It is concluded that the preferential looking task, which has been widely used in group studies, has the potential to act as a reliable index of comprehension level in individual children, especially when movement feedback is used to maintain attention.     

The contribution of temperament,popularity, and physical appearance to children’s happiness

The relation between the happiness of 9–12 year old children and their temperament, popularity, and physical appearance was examined. Participants included 432 children and their parents and teachers. Happiness in children was assessed using a self-rating scale, parents’ ratings, teachers’ ratings, and the Happiness and Satisfaction Subscale of the Piers-Harris Children’s Self-Concept Scale 2 (Piers-Harris 2) [Piers, E. V., & Herzberg, D. S. (2002). Manual for the Piers-Harris Children’s Self-Concept Scale, 2nd ed. Los Angeles: Western Psychological Services]. Estimates of children’s temperament, popularity, and physical appearance included parents’ ratings, individual items on the Piers-Harris 2, and three domain scales from the Piers-Harris 2: the Freedom From Anxiety Subscale, Popularity Subscale, and Physical Appearance and Attributes Subscale. Children’s happiness was correlated with and predicted by ratings of their temperament, popularity, and appearance. Demographic variables did not account for appreciable variance in children’s happiness. The results parallel the common finding that internal factors (e.g., personality), but not external factors (e.g., demographics), predict adults’ happiness.     

Implicit Theories of Organizational Power and Priming Effects on Managerial Power‐Sharing Decisions: An Experimental Study1

Over 60 years of research on participative leadership has documented the many benefits of power sharing in organizations. However, a common obstacle to power sharing is the unwillingness of those with power to share it. An experimental study is presented that investigated the effects of managers' implicit theories of power in organizations on their willingness to share power with subordinates. The study proposed that chronic differences in implicit power theories (the degree of competitive vs. cooperative beliefs and ideals regarding organizational power relations) would affect managers' decisions to share or withhold power. Subliminal priming was predicted to temporarily enhance the accessibility of these differences in implicit power theories, thereby fostering or inhibiting spontaneous decisions to share power. Results indicate that the subliminal priming of competitive theories of organizational power negatively influenced managers' immediate, spontaneous decisions to share power, whereas chronic differences in their implicit theories similarly affected their more systematic decisions to share power. The theoretical and applied contributions of the study are discussed.
