Effects of positive and negative adult-child interactions on children's task performance and task preferences

In individual sessions, an adult directed three boys to work on each of three different tasks. Within a given session the on-task behavior for one task was praised, the off-task behavior for another task was verbally reprimanded, and all behavior was ignored with the third task. Using a multielement baseline design, the manner in which the adult interacted with the children on a given task varied from day to day. Across 18 sessions, verbal reprimands produced the highest task rates, with praise producing only a slightly higher rate of responding than noninteraction. After each session the children were given the choice of which of the three tasks they wished to work on when the adult left the room for a few minutes. Tasks associated with verbal reprimands of off-task behavior were never chosen. The first and second choices were always the task associated with praise for on-task behavior or the task where the children were ignored. These preferences generalized to similar tasks.     

Ear asymmetries on a selective attentional task

To ascertain whether there are ear-hemisphere asymmetries of selective attention, signal stimuli (tonal sequences) were presented monaurally with and without complex maskers (music and speech). The right ear-left hemisphere was more disrupted by language maskers; the left ear-right hemisphere was more disrupted by music maskers. These results suggest that there are hemispheric asymmetries of selective attention and that the ear hemisphere that usually processes a class of stimuli has greater difficulty filtering out those stimuli than does the nonspecialized hemisphere.     

Recognition memory in mentally retarded persons

The continuous recognition memory of retarded and normal subjects was assessed. The stimuli were magazine pictures, arranged so that lags of up to 250 pictures occured. The overall performance of the retarded subjects was poorer, in terms of hit rate or d′. However, the differences were present at 0 lag and the slopes of the forgetting curves were similar in both groups. It was concluded that differences between these subjects were due to a perception related process and not to memory.     

A modern assessment of the basic forms of aphasia

A brief survey of the field of aphasia is presented. Many of the facts described in the neurological classics remain valid, but the interpretation of these facts must be altered. The basic principles of aphasia are reassessed in the light of neuropsychology. Neuropsychological analysis shows sensory (acoustico-gnostic) aphasia to be based upon an impairment in phonemic hearing. Motor aphasia breaks down into afferent (kinesthetic) and efferent (kinetic) aphasia. The former is based upon an impaired kinesthetic input into the speech functions, which results in a special type of oral apraxia. Efferent (kinetic) aphasia is based upon a breakdown in the kinetic organization of speech motor acts. Nominative (amnestic) aphasia consists of a number of forms, each based on either a weakness of visual or auditory analysis or difficulty in selection between evoked memory traces. “Transcortical motor aphasia” proves to be either perseverative aphasia, i.e., aphasia in which the dynamics of plasticity are impaired, or the result of the impairment of internal speech. The basic defect underlying “conduction” aphasia is beginning to be understood as a weakened acoustico-gnostic function or difficulties in retarding sideline associations.     

Enhancing parental reflective functioning through early dyadic interventions: A systematic review and meta‐analysis

Parental reflective functioning (PRF) is an important predictor of infant attachment, and interventions that target parent–infant/toddler dyads who are experiencing significant problems have the potential to improve PRF. A range of dyadic interventions have been developed over the past two decades, some of which explicitly target PRF as part of their theory of change, and some that do not explicitly target PRF, but that have measured it as an outcome. However, no meta‐analytic review of the impact of these interventions has been carried out to date. The aim of this review was to evaluate the effectiveness of dyadic interventions targeting parents of infant and toddlers, in improving PRF and a number of secondary outcomes. A systematic review and meta‐analysis was conducted in which key electronic databases were searched up to October 2018. Eligible studies were identified and data extracted. Data were synthesised using meta‐analysis and expressed as both effect sizes and risk ratios. Six studies were identified providing a total of 521 participants. The results of six meta‐analyses showed a nonsignificant moderate improvement in PRF in the intervention group (standardised mean difference [SMD]: –0.46; 95% confidence interval [CI] [–0.97, 0.04]) and a significant reduction in disorganised attachment (risk ratio: 0.50; 95% CI [0.27, 0.90]). There was no evidence for intervention effects on attachment security (odds ratio: 0.71; 95% CI [0.19, 2.64]), parent–infant interaction (SMD: –0.10; 95% CI [–0.46, 0.26]), parental depression (SMD: –1.55; 95% CI [–3.74, 0.64]) or parental global distress (SMD: –0.19, 95% CI [–3.04, 22.65]). There were insufficient data to conduct subgroup analysis (i.e. to compare the effectiveness of mentalisation‐based treatment with non‐mentalization‐based treatment interventions). Relational early interventions may have important benefits in improving PRF and reducing the prevalence of attachment disorganisation. The implications for future research are discussed.     

Developmental patterns of emotion regulation in toddlerhood: Examining predictors of change and long‐term resilience

Emotion regulation is critical for optimal functioning across a wide range of domains and may be even more important for individuals in high‐risk environments. While evidence suggests that childhood is generally a period of emotion regulation growth and development, research is needed to examine factors that may contribute to deviations from a typical trajectory. In a prospective study of 1,905 children, latent class growth analysis (LCGA) was used to identify trajectory groups of emotion regulation across toddlerhood (age 14–36 months), examine predictors of those trajectory groups from child temperament, parenting behaviors, and environmental risk, and explore predictions of resilience in 5th grade from the identified groups. LGCA supported a three‐class model, with a Stable Incline group, a Decline group, and a Catch‐Up group. Child negative emotionality, positive and negative parenting, and environmental risk predicted group membership. These trajectory groups in toddlerhood were predictive of child resilient functioning in the 5th grade. Our findings highlight the importance of utilizing developmental models of emotion regulation and provide implications for prevention and early intervention services to enhance emotion regulation development in early childhood.
