Five types of personality continuity in childhood and adolescence

This study examines 5 types of personality continuity--structural, mean-level, individual-level, differential, and ipsative--in a representative population (N=498) and a twin and sibling sample (N=548) of children and adolescents. Parents described their children on 2 successive occasions with a 36-month interval using the Hierarchical Personality Inventory for Children (I. Mervielde & F. De Fruyt, 1999). There was evidence for structural continuity in the 2 samples, and personality was shown to be largely differentially stable. A large percentage had a stable trait profile indicative of ipsative stability, and mean-level personality changes were generally small in magnitude. Continuity findings were explained mainly by genetic and nonshared environmental factors.     

How reading acquisition changes children’s spoken language network

To examine the influence of age and reading proficiency on the development of the spoken language network, we tested 6- and 9-years-old children listening to native and foreign sentences in a slow event-related fMRI paradigm. We observed a stable organization of the peri-sylvian areas during this time period with a left dominance in the superior temporal sulcus and inferior frontal region. A year of reading instruction was nevertheless sufficient to increase activation in regions involved in phonological representations (posterior superior temporal region) and sentence integration (temporal pole and pars orbitalis). A top-down activation of the left inferior temporal cortex surrounding the visual word form area, was also observed but only in 9 year-olds (3 years of reading practice) listening to their native language. These results emphasize how a successful cultural practice, reading, slots in the biological constraints of the innate spoken language network.     

Occupationally Embedded Exercise Versus Rote Exercise and Psychosocial Response in College-Aged Females

Community integration through occupational engagement is an integral tenet of occupational therapy. However, little is known about how pets may assist this process. This study explores community integration through pet ownership as a meaningful, lifelong, occupation for one person with bipolar illness receiving Assertive Community Treatment. Using a case study approach, eight qualitative interviews, as well as observation and analysis of pet photos, were conducted with the mental health consumer and also with members of her social network. Data were analyzed inductively according to the constant comparative approach. The findings reveal that pet ownership assisted the person to counterbalance and move beyond stigma through pets as enablers of: “continuity,” “belonging,” “action and self-construction,” “acceptance,” and “participation.” This process was influenced by the “severity of illness,” “view of community,” and “supports and resources.” The results contribute to our understanding of pet ownership as a means to community integration. The study indicates that to enable persons with a mental illness to engage in pet ownership, occupational scientists need to examine and understand this occupation in the broader context of recovery, health, and well-being. A perspective of pet ownership as meaningful occupation challenges occupational therapists to develop strategies to actively engage clients and their pets in their community.     

Semantic processing in auditory lexical decision: Ear-of-presentation and sex differences

In this study we examined the interplay between appetitive (approach) and defensive (avoid) responses in spoken word recognition. Ninety-two right-handed participants (half women) took part in an auditory lexical decision experiment in which speech was presented to only one ear. The danger and usefulness of the word referents interacted in predicting RTs, as in previous (binaural) studies with poorer control of psycholinguistic covariates. Specifically, higher danger ratings were associated with faster RTs for words rated low on usefulness; but higher danger ratings were associated with slower RTs for words rated high on usefulness. In addition to this primary finding, men showed more lateralised performance, as indicated by significant interactions of sex and ear of presentation with word frequency, and with the animacy of the word referents. For both sexes, word frequency had a stronger effect on accuracy for speech presented to the right ear. Finally, men's but not women's RTs were related to the danger dimension. This last finding provides an intriguing avenue for future research in the area of sex differences and emotion.     

Parenting stress and marital relationship as determinants of mothers' and fathers' parenting

Using the actor–partner interdependence model, we explore how various sources of stress and support experienced by fathers and mothers influence their own parenting styles and the parenting styles of the partner. Data from 227 couples were analyzed, with mothers and fathers rating their parenting stress and marital relationship and children rating the parenting styles of both mothers and fathers. Structural equation models revealed actor effects of parenting stress on demanding and responsive parenting styles, as well as partner effects between positive aspects of marital relationship and responsive parenting style. The results further indicate that the strength of these pathways is similar for both mothers and fathers and do not support the hypothesis that the parenting of fathers is more vulnerable than the parenting of mothers.     

The Influence of Mothers' and Fathers' Parenting Stress and Depressive Symptoms on Own and Partner's Parent‐Child Communication

This study examines how parenting stress and depressive symptoms experienced by mothers and fathers influence their own (actor effects) and the partner's (partner effects) parent–child communication. Based on the Actor‐Partner Interdependence Model, data from 196 families were analyzed, with both parents rating their parenting stress and depressive feelings, and parents as well as children rating the open parent–child communication. Actor effects were found between parenting stress and open parent–child communication, whereas partner effects were prominent between depressive symptoms and open parent–child communication. The results provide no evidence for gender differences in the strength of the pathways to open parent–child communication. Our findings demonstrate the need to include both parents in studies on parent–child communication to enhance our understanding of the mutual influence among family members.     

Assessment of Pretend Play in Preschool-Aged Children: Validation and Factor Analysis of the Affect in Play Scale–Preschool Version

The Affect in Play Scale–Preschool (APS–P) and Affect in Play Scale–Preschool–Brief Rating (APS–P–BR) versions assess cognitive and affective play processes during a 5-min standardized play task. In this study, construct validity, external validity, and factor analyses for each scale were examined in 107 preschoolers. Reliability and validity were supported. Unlike results found with school-aged samples, positive affect loaded with the cognitive variables on factor analyses of the APS–P and APS–P–BR, suggesting that negative and undefined affect might represent a separate factor in preschool-aged children. Developmental significance and implications for use of the 2 scoring versions are discussed.     

Does visual expertise improve visual recognition memory?

In general, humans have impressive recognition memory for previously viewed pictures. Many people spend years becoming experts in highly specialized image sets. For example, cytologists are experts at searching micrographs filled with potentially cancerous cells and radiologists are expert at searching mammograms for indications of cancer. Do these experts develop robust visual long-term memory for their domain of expertise? If so, is this expertise specific to the trained image class, or do such experts possess generally superior visual memory? We tested recognition memory of cytologists, radiologists, and controls with no medical experience for three visual stimulus classes: isolated objects, scenes, and mammograms or micrographs. Experts were better than control observers at recognizing images from their domain, but their memory for those images was not particularly good (D’ ~ 1.0) and was much worse than memory for objects or scenes (D’ > 2.0). Furthermore, experts were not better at recognizing scenes or isolated objects than control observers.
