Recency effects in direct and indirect memory tasks

In three experiments, subjects learned two lists under incidental conditions and were then given either a part-word or a word (extralist associate) cue. Each cue was related to one word in each list. Half the subjects were given production instructions (an indirect memory test), and half were given cued recall instructions (a direct memory test). When the interval between List 2 and the test was shortened, recency effects were found for part-word cues for both cued recall and production instructions. Little or no recency effects were found with word cues. These results are incompatible with a simple distinction between the types of memory trace or information that are tapped by direct as opposed to indirect memory tasks. Possible causes for the recency effect and for the difference between word and part-word cues are discussed.     

Development of a structured psychiatric interview for children: Agreement between child and parent on individual symptoms

To test the reliability of children's reporting as compared with that of their mothers, a highly structured psychiatric diagnostic interview was used with 307 subjects, ages 6 through 16. Another interviewer gave each mother a similar interview about the child. Responses of each mother-child pair to 168 questions were compared using the kappa statistic. Highest agreement was found on questions concerning symptoms that are concrete, observable, severe, and unambiguous. Mothers tended to report significantly more behavioral symptoms, and children more subjective symptoms. Reasons for low kappas and asymmetrical reporting of symptoms are discussed.     

Trauma exposure and post-traumatic stress symptoms among Syrian refugee youth in Jordan: Social support and gender as moderators

This study assessed relations between exposure to trauma and post-traumatic stress (PTS) symptoms, and whether perceived social support from family and friends and gender moderated these associations. Syrian refugee youth (N = 418, 55.0% female) attending public schools in Jordan participated. Boys reported more age-adjusted PTS symptoms than girls. Analyses revealed that family support and gender moderated the association of trauma on PTS symptoms. For males, the benefits of family support were most evident under conditions of high traumatic stress exposure, while for females, benefits of family support were evident when no loss or injury to family members had been reported. Support from friends was not helpful for either gender. School- or family-based interventions designed to treat PTS symptoms need to consider the different needs of boys and girls, particularly within the Syrian Muslim cultural context.

Effects of Stimulant Medication Treatment on Mothers' and Children's Attributions for the Behavior of Children with Attention Deficit Hyperactivity Disorder

Participants were 55 children with attention deficit hyperactivity disorder (ADHD) who were receiving ongoing treatment with stimulant medications and their mothers, and 31 children with ADHD who were beginning stimulant medication and their mothers. Mothers and children offered attributions for child behaviors that occurred when the child was medicated and not medicated. Mothers rated child compliance and prosocial behavior as more global and stable when the child was medicated and rated noncompliance, ADHD symptoms, and oppositional behavior as more externally caused, less global and stable, but more controllable by the child when the child was medicated. Children rated both their compliance and noncompliance as more controllable in the medicated condition. On a forced-choice measure, both mothers and children selected ability, effort, and task attributions for compliance more in the not-medicated condition, and pill-taking attributions more in the medicated condition. This was reversed for noncompliance, which was attributed more to effort, task, or ability in the medicated condition and more to not taking a pill in the not-medicated condition. The potential risks and benefits for parent–child interactions and children's self-perceptions of these medication-related differences in attributions are discussed.     

Neural mechanisms of affective interference in schizotypy

Negatively valenced stimuli foster cognitive impairment in schizotypy and schizophrenia. To identify relevant brain mechanisms, the authors had 16 positive-schizotypy and 16 control participants perform an emotional Stroop task, judging the ink color of negative and neutral words during functional magnetic resonance imaging (fMRI) of regional brain activity. Schizotypy individuals showed increased right and decreased left activity in dorsolateral prefrontal cortex, indicating a deficit in maintenance of attentional set in the presence of negative emotional distractors. They also showed abnormal activity in ventral limbic areas, including decreased activity in nucleus accumbens and increased activity in hippocampus and amygdala, a circuit involved in the integration of cognitive and affective processes. These results indicate that aspects of emotion-cognition processes and the brain mechanisms that implement them are similar in schizotypy and schizophrenia.
