Temperature reinforcement for visual discrimination training in baby chicks

A fully automated training apparatus, using thermoregulation as performance incentive, was constructed to train baby chicks on visual discrimination and reversal problems. In the base condition, the S is bathed in cold air in a small training cubicle. Two stimuli are back-projected onto two display windows according to a pseudorandom balanced schedule. A peck at the positive stimulus gives convective as well as radiant heat reward with adjustable temperature and duration. A peck at the negative stimulus merely advances the program to the next trial. Permanent printout records give trial-to-trial information on response choice and latency. Performance data of 64 Ss are reported.     

Maternal Depression and Parent Management Training Outcomes

This study examines the impact of maternal depression on reductions in children’s behavior problems severity following implementation of the Brief Behavioral Intervention—a brief, manualized parent management training treatment. The parents of 87 children aged 2–6 years of age received parent management training at a metropolitan hospital. Parents of participants completed measures of externalizing behavior and maternal depression. The association between pre-post treatment change in externalizing behavior and maternal depression was examined using an autoregressive cross-lagged model. Results showed that self-reported maternal depressive symptoms at pre-treatment negatively influenced the overall magnitude of reduction of reported externalizing behaviors in children following treatment. Results indicate that aspects of family functioning not specifically targeted by parent management training, such as maternal depression, significantly affect treatment outcomes. Clinicians providing parent management training may benefit from assessing for maternal depression and modifying treatment as indicated.     

Evaluation of a conflict-resolution and problem-solving programme to enhance adolescents' self-concept

The effectiveness of an intervention programme, initially designed to enhance the self-concept and motivation of gifted underachieving girls, was evaluated for students identified as having a low self-concept and social relationship difficulties. Twenty male and female secondary-school students were randomly assigned to either a treatment or a control group. The programme, called ABLE (Attribution, Behaviour, Life skills Education), incorporates problem-solving, conflict resolution, and a multidimensional framework to investigate adolescents' self-concept formation. The adolescents in the study made significant improvements in the areas of general self-concept, physical appearance self-concept, and total self-concept. Teaching conflict-resolution and problem-solving skills had a beneficial influence on self-concept. The results are discussed in terms of the relevance of the programme and its application to school and counselling interventions.     

Demystifying infant vocal imitation: The roles of mouth looking and speaker’s gaze

Vocal imitation plays a fundamental role in human language acquisition from infancy. Little is known, however, about how infants imitate other's sounds. We focused on three factors: (a) whether infants receive information from upright faces, (b) the infant's observation of the speaker's mouth and (c) the speaker directing their gaze towards the infant. We recorded the eye movements of 6‐month‐olds who participated in experiments watching videos of a speaker producing vowel sounds. We found that an infants’ tendency to vocally imitate such videos increased as a function of (a) seeing upright rather than inverted faces, (b) their increased looking towards the speaker's mouth and (c) whether the speaker directed their gaze towards, rather than away from infants. These latter findings are consistent with theories of motor resonance and natural pedagogy respectively. New light has been shed on the cues and underlying mechanisms linking infant speech perception and production.     

Encouraging children to mentalise about a perceived outgroup increases prosocial behaviour towards outgroup members

We investigated whether encouraging young children to discuss the mental states of an immigrant group would elicit more prosocial behaviour towards them and impact on their perception of a group member's emotional experience. Five‐ and 6‐year‐old children were either prompted to talk about the thoughts and feelings of this social group or to talk about their actions. Across two studies, we found that this manipulation increased the extent to which children shared with a novel member of the immigrant group who was the victim of a minor transgression. The manipulation did not lead to greater sharing towards a victim from the children's own culture and did not influence their perception of a victim's negative emotions. These results may ultimately have implications for interventions aimed at fostering positive intergroup relations within the context of immigration.     

Associations of Parent-Adolescent Discrepancies in Family Cohesion and Conflict with Adolescent Impairment

Family cohesion and family conflict are important protective and risk factors respectively in the development of child psychopathology. Our study examines parent-adolescent discrepancy of the family environment constructs, family cohesion and family conflict, and their associations with adolescent impairment. The sample consists of 141 parent-adolescent dyads evaluated at an outpatient behavioral health clinic. The mean adolescent age is 14.8 (range 11–18) while the mean parent age is 48.9 (range 32–67). Findings show that adolescents report significantly less family cohesion but do not differ significantly in reports of family conflict. Greater family cohesion is associated with less adolescent impairment by multiple reporters. Nonetheless, greater family conflict is associated with more adolescent impairment by the same reporter. The results show that both adolescent and parent reports of family cohesion and conflict are important to consider when integrating information gathered in a clinical assessment.
