Children's eyewitness reports after exposure to misinformation from parents.

This study examined how misleading suggestions from parents influenced children's eyewitness reports. Children (3 to 8 years old) participated in science demonstrations, listened to their parents read a story that described experienced and nonexperienced events, and subsequently discussed the science experience in two follow-up interviews. Many children described fictitious events in response to open-ended prompts, and there were no age differences in suggestibility during this phase of the interview. Accuracy declined markedly in response to direct questions, especially for the younger children. Although the older children retracted many of their false reports after receiving source-monitoring instructions, the younger children did not. Path analyses indicated that acquiescence, free recall, and source monitoring all contribute to mediating patterns of suggestibility across age. Results indicate that judgments about the accuracy of children's testimony must consider the possibility of exposure to misinformation prior to formal interviews.

Prenatal diagnosis of total arhinia.

Complete or total arhinia, in which there is absence of the soft tissue of the nose, is extremely rare. The embryological origin of the defect is thought to be maldevelopment of the paired nasal placodes. Available neonatal case descriptions have reported the frequent coexistence of other facial anomalies. This report is the first to describe the antenatal diagnosis of total arhinia confirmed after delivery. Sonographic views of the fetal profile, showing an absence of the nose led to consideration of the diagnosis.

Efficient coding of eyewitness narratives: a comparison of syntactic unit and word count procedures.

Researchers rely on two types of coding systems to evaluate eyewitness narratives. Features-of-events checklists offer coding simplicity but are impractical when target events are complex. Units-of-information (UOI) systems score all information reported, regardless of event complexity, but are difficult to implement. To test whether simpler systems would alter conclusions about memory performance, transcripts from children (3-8 years of age) who participated in an eyewitness study, originally coded using a UOI system called syntactic units (SU), were recorded using two word count procedures. Correlations between SU, modified word count, and raw word count values were high, and the proportion of information that was inaccurate was comparable across systems. Considering their high interrater reliability, procedural simplicity, and convergence with SU coding, word count procedures are efficient alternatives to UOI coding.

Psychotherapy and the recovery of memories of childhood sexual abuse: U.S. and British practitioners' opinions, practices, and experiences.

Licensed U.S. doctoral-level psychotherapists randomly sampled from the National Register of Health Service Providers in Psychology (Surveys 1 and 2, n = 145; Council for the National Register of Health Service Providers in Psychology, 1992) and British psychologists sampled from the Register of Chartered Clinical Psychologists (Survey 2, n = 57; British Psychological Society, 1993) were surveyed regarding clients' memories of childhood sexual abuse (CSA). The 3 samples were highly similar on the vast majority of measures. Respondents listed a wide variety of behavioral symptoms as potential indicators of CSA, and 71% indicated that they had used various techniques (e.g., hypnosis, interpretation of dreams) to help clients recover suspected memories of CSA. Across samples, 25% of the respondents reported a constellation of beliefs and practices suggestive of a focus on memory recovery, and these psychologists reported relatively high rates of memory recovery in their clients.

Induction of parturition in dairy cows with dexamethasone.

Sixty Holstein cows were paired by parity and sire, and one of each pair was allocated at random to treatment or control; 17 cows were injected with 7.5 mg/100 kg dexamethasone trioxa undecanoate 14 days before the predicted date of calving, 13 cows received the same dose five days before term and 30 cows were left untreated. The treatment significantly advanced parturition and 29 of the 30 induced cows calved within 72 hours of the injection. Induction at day 14 before term was safe for calf and dam, the calves were 3.2 kg lighter than control calves and there was a high incidence of retained placenta. Treatment for this condition resulted in increased veterinary costs of 14.50 pounds per cow exclusive of dexamethasone treatment. Treatment at this stage was also associated with low pregnancy rates in the next breeding season. Calves born after induction at five days before term were not significantly lighter than calves from control cows, the problem of retained placenta was less marked and there were no subsequent effects on fertility. There were no significant effects of induction on milk yield or milk quality up to 200 days of lactation.

A comparative study of black South African children from three different contexts.

This study compares family characteristics and developmental outcomes of black children (N = 300) from 3 rural contexts in South Africa: the homeland, the resettlement, and the white-owned farms. Parents in the homeland were more likely to be married and had more education, less household crowding, and lower mobility than parents in the other 2 areas, and higher occupational status than parents from the farms. Child outcomes paralleled these differences in material resources and family stability. Children from the homeland scored higher than children from the resettlement or farms on head circumference, vocabulary, quantitative skill, and self-concept, with no significant differences between the latter 2 areas on these outcome variables. Children from the homeland also scored higher than resettlement children on weight, copying skill, and height, with children from the farms measuring lowest on height. Child outcomes were highly intercorrelated in all 3 residence areas, but correlations among family variables, and between family and child variables, showed different patterns across areas. Parent education, occupation, and crowding were the most consistent predictors of physical development, cognitive development, and self-concept. Family mobility and marital status, however, showed different relationships to other family variables and to child outcomes across the 3 environments. These results highlight the importance of studying children in multiple environmental contexts, because family characteristics are not associated uniformly across residence areas.

Accuracy of respiratory inductive plethysmographic cross-sectional areas.

The present study was undertaken to evaluate whether the respiratory inductive plethysmograph (RIP) 1) reflects changes of cross-sectional area enclosed by its transducer band in the presence of deformations of shape or whether it 2) has a stable base line. Testing of RIP was carried out with a device incorporating a thermally compensated oscillator and digital demodulatory circuitry. This system, introduced to commerce in 1983, superceded the nonthermal compensated oscillatory and analog demodulator circuitry first used in 1977. Testing the effects of changing cross-sectional area was accomplished by stretching a standard RIP transducer band around wooden dowels placed in holes on a peg board grid to form 23 curved and 5 rectangular shapes. The output voltage from RIP was linear for both the curved and rectangular shapes for changes of cross-sectional area within a physiological range. However, the regression line of voltage vs. cross-sectional area for the rectangular shapes was parallel and slightly displaced from the regression line for the curved shapes due to mutual coupling of inductance in the corners. Base-line drift from a RIP transducer band stretched to enclose an elliptical shape was less than 2.5 mV over a 12-h observation period. Current RIP technology accurately reflects changes of cross-sectional area of physiological shapes and has a stable base line.
