Effect of Short-Term Training on Reaching Behavior in Infants: A Randomized Controlled Clinical Trial

The purpose of this study was to test the effect of short-term training on reaching behavior in infants at the onset of reaching. The study was a single-blind, parallel group design, randomized controlled clinical trial. Thirty healthy infants were randomly assigned to a social control group (n = 15) or a reaching training group (n = 15). Infants began the study up to 3 days after the onset of reaching and were assessed three times across 2 days: pretraining (before training), posttraining 1 (after 1 session of training), and posttraining 2 (after 3 sessions of training). The reaching training group received 3 sessions of training by a physical therapist while the control group received a similar amount of time sitting in the therapist's lap. The data were analyzed using repeated-measures analyses of variance, and independent-samples tests with Bonferroni adjustments. Short-term training resulted in increased frequency of object contacts, shorter and smoother reaches, and improved hand positioning. The few short training sessions likely provided opportunities for infants to explore and learn to select movements from their existing movement repertoire. These results demonstrate that adaptive changes in infants' novel behaviors can emerge rapidly, and highlight the need for increased understanding of how to most effectively time early interventions.     

Predicting early emotion knowledge development among children of colour living in historically disinvested neighbourhoods: consideration of child pre-academic abilities,self-regulation,peer relations and parental education

ABSTRACT

Emotion knowledge, the ability to accurately perceive and label emotions, predicts higher quality peer relations, higher social competence, higher academic achievement, and fewer behaviour problems. Less is known, however, about predictors of early development of emotion knowledge. This study examines emotion knowledge development among children attending pre-Kindergarten and Kindergarten programmes in high-poverty urban schools. The study considers child pre-academic abilities, self-regulation, peer relations and parental education as predictors of emotion knowledge development over two years. The sample (n?=?1034) of children living in historically disinvested neighbourhoods was primarily Black (85%) and low-income (～61%). The sample was part of a longitudinal follow-up study of a cluster (school) randomised controlled trial in ten public elementary schools. Children’s emotion knowledge was assessed with a series of tasks three times over a two-year period. At baseline, parents and teachers reported on peer relations, children completed a test of pre-academic abilities, independent observers rated child self-regulation, and parents reported on their educational attainment. Results demonstrate that emotion knowledge increases over time, and pre-academic abilities, self-regulation, peer relations, and parent education independently predict children’s emotion knowledge. This study highlights multiple factors that predict emotion knowledge among primarily Black children living in historically disinvested neighbourhoods.     

The effect of very brief exposure on experienced fear after in vivo exposure

Two experiments tested the effect of exposure to masked phobic stimuli at a very brief stimulus onset asynchrony on reducing the subjective experience of fear caused by in vivo exposure to a feared object. In the main experiment, 35 spider-fearful and 35 non-fearful participants were identified with a questionnaire and a Behavioural Avoidance Test (BAT) with a live tarantula. One week later, they were individually administered one of two continuous series of masked images: spiders or flowers. They engaged in the BAT again immediately thereafter. They provided ratings of subjective fear at the end of each BAT (pre- and post-manipulation). Very brief exposure to images of spiders reduced the fearful group's and not the non-fearful group's experience of fear at the end of the BAT. This effect was replicated with another sample of 26 spider-fearful participants from the same population. Theoretical implications are discussed.     

Identification as a Focal Point in Couple Therapy

It is impossible to speak meaningfully about a couple's relationship without giving full consideration to the way the partners' childhood experiences have influenced their identities. Each partner is affected by his or her relationships with both parents and by intimacy beliefs shaped through observations of the parents' marriage. Often, unconscious identifications underlie the interactions that lead distressed couples to seek therapy. This paper explores two concepts that can assist therapists in repairing the present in the context of the past—projective identification and disidentification. Consideration is given to the power of the parents' marriage and to identifications based on individual parents.     

Transitioning Between Systems of Care: Missed Opportunities for Engaging Adults with Serious Mental Illness and Criminal Justice Involvement

Individuals with serious mental illness are overrepresented in the criminal justice system and face difficulties accessing mental health services both during incarceration and upon re‐entry into the community. This study examines how such individuals describe their experiences receiving care both during and after their time in custody and explores the perspectives of mental health service providers who treat this population upon re‐entry. Semi‐structured interviews were conducted with 43 individuals identified as having a history of serious mental illness and criminal justice involvement, as well as with 25 providers who have worked with this population. Clients noted the stress of transitioning to criminal justice settings, the uneven availability of services within jail and prison, and the significant challenges faced upon re‐entry. Providers reported barriers to working with this population, including minimal coordination with the criminal justice system and challenging behaviors and attitudes on the part of both clients and providers. Findings identify potential target areas for improved care coordination as well as for additional provider education regarding the unique needs of this population.

An Application of the LC-LSTM Framework to the Self-esteem Instability Case

The present research evaluates the stability of self-esteem as assessed by a daily version of the Rosenberg (Society and the adolescent self-image, Princeton University Press, Princeton, 1965) general self-esteem scale (RGSE). The scale was administered to 391 undergraduates for five consecutive days. The longitudinal data were analyzed using the integrated LC-LSTM framework that allowed us to evaluate: (1) the measurement invariance of the RGSE, (2) its stability and change across the 5-day assessment period, (3) the amount of variance attributable to stable and transitory latent factors, and (4) the criterion-related validity of these factors. Results provided evidence for measurement invariance, mean-level stability, and rank-order stability of daily self-esteem. Latent state-trait analyses revealed that variances in scores of the RGSE can be decomposed into six components: stable self-esteem (40 %), ephemeral (or temporal-state) variance (36 %), stable negative method variance (9 %), stable positive method variance (4 %), specific variance (1 %) and random error variance (10 %). Moreover, latent factors associated with daily self-esteem were associated with measures of depression, implicit self-esteem, and grade point average.     

Voting and Values: Reciprocal Effects over Time

Two studies investigated reciprocal effects of values and voting. Study 1 measured adults' basic values and core political values both before (n = 1379) and following (n = 1030) the 2006 Italian national election. Both types of values predicted voting. Voting choice influenced subsequent core political values but not basic values. The political values of free enterprise, civil liberties, equality, law and order, military intervention, and accepting immigrants changed to become more compatible with the ideology of the chosen coalition. Study 2 measured core political values before (n = 697) and following (n = 506) the 2008 Italian national election. It largely replicated the reciprocal effects of voting and political values of Study 1. In addition, it demonstrated that left‐right ideology mediated the reciprocal effects of voting and political values. Moreover, voter certainty moderated these effects. Political values predicted vote choice more weakly among undecided than decided voters, but voting choice led to more value change among undecided voters.     

Artifacts as Conventional Objects

What underlies children's understanding of artifacts? Studies suggest that beginning around age 7, people reason about artifacts in terms of the inventor's purpose—termed the design stance. Our two studies emphasize another component of artifact understanding—the cultural nature of artifacts—by demonstrating people's sensitivity to an artifact's conventional use. In past studies participants were shown a novel artifact and told that someone invented it for a certain purpose and that later another person used it for a different purpose. Here we demonstrate that if participants are told that many people, as opposed to just one person, use an artifact differently, 5-year-olds, 7-year-olds, and adults do not strictly judge the artifact in terms of its invented purpose. We conclude that people's conceptions of artifacts are more complex and dynamic than has been suggested.
