Child-Directed Speech Produced by Mothers with Symptoms of Depression Fails to Promote Associative Learning in 4-Month-Old Infants

Child-directed (CD) speech segments produced by 20 mothers who varied in self-reported symptoms of depression, recorded during a structured play interaction with their 2- to 6-month-old infants, were used as conditioned stimuli with face reinforcers in a conditioned attention paradigm. After pairings of speech segments and faces, speech segments were assessed for their ability to increase time spent looking at a novel checker-board pattern (summation test) using 225 4-month-old infants of nondepressed mothers. Significant positive summation, an index of associative learning, was obtained in groups of infants tested with speech produced by mothers with comparatively fewer self-reported symptoms of depression (Beck Depression Inventory or BDI < or = 15). However, significant positive summation was not achieved using speech samples produced by mothers with comparatively more symptoms of depression (BDI > 15). These results indicate that the CD speech produced by mothers with symptoms of depression does not promote associative learning in infants.     

Extended Visual Fixation in Young Infants: Look Distributions, Heart Rate Changes, and Attention

Visual fixation in in ants from 3 to 6 months of age was examined for its fit to the theory of "attentional inertia." This theory posits that during the progression of a look there is increasing attention toward the stimulus and an "inertia" to continue looking. An extended audiovisual stimulus was presented for 20 min to infants while fixation was videotaped and heart rate (HR) was recorded. Consistent with the attentional inertia theory, look duration toward the stimulus had a lognormal distribution. Hazard functions describing these distributions showed a decreasing conditional probability of looking away with increases in look duration. Look onset and stimulus changes that occurred within a look were accompanied by HR deceleration. The average HR level continued to decrease over the duration of a look and returned to prestimuls level immediately look and returned to prestimulus level immediately prior to the fixation offset. Infant fixation has characteristics similar to fixation in children and adults, and attention appears to increase over to the course of a look in young infants.     

Do Infants Use Their Own Images to Locate Objects Reflected in a Mirror?

The ability of infants to locate a toy from a mirror reflection was investigated in 3 experiments. In the first, it was found that a minority of 22-month-old infants turned to locate the toy that was the source of the reflection, and that localization of the toy occurred regardless of whether the infants' own image was visible in the mirror. The results of 2 further experiments indicated that younger infants aged 14 and 18 months rarely use mirror information to locate a toy. When they do so, they also turn whether or not images of themselves are visible. It is concluded that tasks involving the localization of objects or events from mirror images are not direct indices of self-recognition. Rather, they indicate the skill of infants in using the mirror as a perceptual tool.     

Visual Short‐Term Memory for Complex Objects in 6‐ and 8‐Month‐Old Infants

Infants' visual short‐term memory (VSTM) for simple objects undergoes dramatic development: Six‐month‐old infants can store in VSTM information about only a simple object presented in isolation, whereas 8‐month‐old infants can store information about simple objects presented in multiple‐item arrays. This study extended this work to examine the development of infants' VSTM for complex objects during this same period (N = 105). Using the simultaneous streams change detection paradigm, Experiment 1 confirmed the previous developmental trajectory between 6 and 8 months. Experiment 2 showed that doubling the exposure time did not enhance 6‐month‐old infants' change detection, demonstrating that the developmental change is not due to encoding speed. Thus, VSTM for simple and complex objects appears to follow the same developmental trajectory.

Cortisol Release in Infants in Response to Inoculation

Using a cross-sectional design, salivary cortisol was obtained from infants aged 2, 4, and 6 months, prior to and 15 min following an inoculation. Cortisol rose significantly following inoculation. Behavioral responses to inoculation were consistent with the observed patterns of cortisol release. Cortisol base level was significantly and negatively related to the cortisol change score. At 6 months the basal levels also were influenced by an adult-like circadian rhythm; infants tested shortly after awakening had higher basal levels than those tested later in the day. These data provide strong evidence that studies of stress and cortisol release in infants must be sensitive to basal level, circadian rhythm, and behavioral effects, and that appropriate statistical procedures should be employed.     

Field Dependence-Field Independence in 5- to 10-Year-Old Children

Abstract

A final random sample of 160 Provo, Utah, elementary school children ages 5 to 10, was included in a balanced cell format to investigate the effects of school as reflective of socioeconomic level, age, sex, and intelligence on performance on the Children’s Embedded Figures Test (CEFT), a measure of Witkin’s field-dependence-independence hypothesis appropriate for use with young children. Results implied that (1) there may be differences on criterion performance according to relative social class; (2) age is the single best predictor of criterion performance, as significant differences proceeding from relative field-dependence to greater field-independence with increasing age were found; (3) there is a similar developmental pattern to increase in verbal intellectual power and increase in relative field-independence when all ages are considered together; (4) there were no significant similarities between field-dependence-independence and verbal intelligence within three of four specific ages investigated; (5) no sex differences in criterion performance were found.

英语教学中paraphrase的对象

从调研中引出讨论的问题,进而分析paraphrase的含义及在英语教学中的重要作用,然后通过实例,重点对教学中paraphrase的对象进行论述。笔者认为paraphrase的对象是一些难于理解的词或词组、一些不同的句式、一些特殊形式虚拟语气句子和一些修辞句。只有弄清楚了paraphrase的对象,才能进行正确的paraphrase教学,切实提高学生的综合语言能力。
