Convergence among multiple methods of measuring positivity and negativity in the family environment: relation to depression in mothers and their children

The present study addressed the following questions: (a) To what extent do different methods of measuring the family environment converge onto a single latent construct? (b) How are the constructs of positive and of negative family environment related? (c) Do the associations among various methods of measuring the family environment differ as a function of children's gender or of risk? and (d) How are the latent constructs of family environment related to depression in mothers and their children? Participants were 240 children (mean age = 11.86 years, SD = 0.57) and their mothers, who varied with regard to their history of depression. Family environment was measured with self-report questionnaires completed separately by mothers and by children, observations of mother-child interactions, and a 5-min speech sample of each mother talking about her child. Confirmatory factor analyses revealed that different methods for assessment of the family environment converged and that the constructs of positive and of negative family environments were significantly related to each other and to depression in both mothers and their children. These findings may help inform future intervention efforts by highlighting specific parenting dimensions that are strongly associated with maternal and with child depression.     

Individual differences in delay discounting: relation to intelligence, working memory, and anterior prefrontal cortex

Lower delay discounting (better self-control) is linked to higher intelligence, but the basis of this relation is uncertain. To investigate the potential role of working memory (WM) processes, we assessed delay discounting, intelligence (g), WM (span tasks, 3-back task), and WM-related neural activity (using functional magnetic resonance imaging) in 103 healthy adults. Delay discounting was negatively correlated with g and WM. WM explained no variance in delay discounting beyond that explained by g, which suggests that processes through which WM relates to delay discounting are shared by g. WM-related neural activity in left anterior prefrontal cortex (Brodmann's area 10) covaried with g, r= .26, and delay discounting, r=-.40, and partially mediated the relation between g and delay discounting. Overall, the results suggest that delay discounting is associated with intelligence in part because of processes instantiated in anterior prefrontal cortex, a region known to support the integration of diverse information.     

What determines auditory similarity? The effect of stimulus group and methodology

Two experiments on the internal representation of auditory stimuli compared the pairwise and grouping methodologies as means of deriving similarity judgements. A total of 45 undergraduate students participated in each experiment, judging the similarity of short auditory stimuli, using one of the methodologies. The experiments support and extend Bonebright's (1996) findings, using a further 60 stimuli. Results from both methodologies highlight the importance of category information and acoustic features, such as root mean square (RMS) power and pitch, in similarity judgements. Results showed that the grouping task is a viable alternative to the pairwise task with N > 20 sounds whilst highlighting subtle differences, such as cluster tightness, between the different task results. The grouping task is more likely to yield category information as underlying similarity judgements.     

Parental Depression and Child Externalizing and Internalizing Symptoms: Unique Effects of Fathers’ Symptoms and Perceived Conflict as a Mediator

Although a developing body of literature suggests that depressive symptoms in fathers are related to child psychopathology, little evidence suggests that paternal depression plays a unique role in children’s symptoms. We used a high-risk design involving children of mothers with and without histories of depression to test the unique mediating role of father–child conflict in the relations between fathers’ depressive symptoms and child externalizing and internalizing symptoms. In all regression analyses, mothers’ history of depression and current depressive symptoms were controlled. Depressive symptoms in fathers were associated with child externalizing and internalizing symptoms, and father–child conflict. Father–child conflict mediated relations between fathers’ depressive symptoms and child externalizing symptoms above and beyond the effects of maternal depression history and depressive symptoms. The results suggest that negative interpersonal consequences of parental depression on child psychopathology may not be limited to mothers.     

Affect, Social Behavior, and the Brain in Williams Syndrome

ABSTRACT— Williams syndrome (WS) is a rare genetic disorder characterized by intellectual impairment and a distinctive physical and neuropsychological profile. Relative to their level of intellectual functioning, individuals with WS exhibit strengths in language and face recognition, with deficits in visual-spatial cognition. A heightened appetitive drive toward social interaction is a strong behavioral feature. Relative to other neurodevelopmental disorders, WS has a clearly defined genetic basis, together with a consistent neurocognitive profile of strengths and deficits. Thus, this disorder offers unique opportunities for elucidating gene–brain–behavior relationships. We focus on manifestations of the unusual social profile in WS, by examining data within and across levels of cognition, brain, and molecular genetics.     

Semantic interference on a phonological task in illiterate subjects

Previous research suggests that learning an alphabetic written language influences aspects of the auditory-verbal language system. In this study, we examined whether literacy influences the notion of words as phonological units independent of lexical semantics in literate and illiterate subjects. Subjects had to decide which item in a word- or pseudoword pair was phonologically longest. By manipulating the relationship between referent size and phonological length in three word conditions (congruent, neutral, and incongruent) we could examine to what extent subjects focused on form rather than meaning of the stimulus material. Moreover, the pseudoword condition allowed us to examine global phonological awareness independent of lexical semantics. The results showed that literate performed significantly better than illiterate subjects in the neutral and incongruent word conditions as well as in the pseudoword condition. The illiterate group performed least well in the incongruent condition and significantly better in the pseudoword condition compared to the neutral and incongruent word conditions and suggest that performance on phonological word length comparisons is dependent on literacy. In addition, the results show that the illiterate participants are able to perceive and process phonological length, albeit less well than the literate subjects, when no semantic interference is present. In conclusion, the present results confirm and extend the finding that illiterate subjects are biased towards semantic-conceptual-pragmatic types of cognitive processing.     

Young children's use of scale models: testing an alternative to representational insight

Using a symbolic object such as a model as a source of information about something else requires some appreciation of the relation between the symbol and what it represents. Representational insight has been proposed as essential to success in a symbolic retrieval task in which children must use information from a hiding event in a scale model to find a toy hidden in a room. The two studies reported here examine and reject a proposed alternative account for success in the model task. The results with 2.5-year-olds and 3-year-olds show that children's successful use of a scale model cannot be attributed to the simple detection of the correspondences between the objects in the two spaces. A higher-level representation of the model-room relation (i.e. representational insight) is required. The results are discussed with respect to the coalescence of multiple factors in determining performance in the model task.     

The BUFFET Program: Development of a Cognitive Behavioral Treatment for Selective Eating in Youth with Autism Spectrum Disorder

Selective eating (often referred to as “picky” eating) is common in individuals with autism spectrum disorder (ASD) across the lifespan. Behavioral interventions are widely used to treat selective eating; however, most of these programs are time intensive, have not been evaluated for use in outpatient settings, and do not typically include youth beyond early childhood. Despite the functional impact and risk for negative outcomes associated with selective eating, there are no empirically supported treatments available for older children, adolescents, or adults, either with or without ASD. To address this treatment gap, we developed BUFFET: the Building Up Food Flexibility and Exposure Treatment program. BUFFET is a 14-week, multi-family group cognitive behavioral treatment for selective eating in children (8–12 years) with ASD. In this paper, we will (1) discuss the theoretical conceptualization of BUFFET, (2) describe the treatment content and structure, (3) present feasibility data from the initial pilot trial, and (4) consider next steps in treatment development.     

Caregiving representations of mothers of behaviorally inhibited and uninhibited preschool children

This study examined differences in the caregiving representations of mothers of 3- to 4-year-old behaviorally inhibited and uninhibited children with secure or insecure attachments. Mothers of inhibited children perceived their children as more vulnerable than did mothers of uninhibited children, and they acknowledged difficulties associated with their children's inhibited temperament. However, mothers of insecure inhibited children were less likely than mothers of secure inhibited children to validate their children's emotional experiences and to be aware of their children's internal states and perspectives, and they showed higher levels of boundary violation and defense against negative affect. Implications of the more problematic caregiving representations of mothers of insecure inhibited children for parent-child relationships are discussed.
