Head orientation was investigated in a longitudinal study of 37 infants, who were observed at ages 2, 4, 8, and 12 weeks, during a 60-second period that followed each of four (60 second) midline or lateral holds. When newborn, the infants tended to lie with their heads to the right, but this bias weakened over the first 3 postnatal months. This rightward motor bias was constrained further by such factors as sex and holding position; both factors had their strongest effect at 8 weeks. Finally, evidence was found for behavioral reorganization of postural orientation such that head orientation was less influenced by prior head positioning after than prior to 8 weeks. 相似文献

We investigated whether adult learners' knowledge of phonotactic restrictions on word forms from their first language impacts their ability to use statistical information to segment words in a novel language. Adults were exposed to a speech stream where English phonotactics and phoneme co-occurrence information conflicted. A control where these did not conflict was also run. Participants chose between words defined by novel statistics and words that are phonotactically possible in English, but had much lower phoneme contingencies. Control participants selected words defined by statistics while experimental participants did not. This result held up with increases in exposure and when segmentation was aided by telling participants a word prior to exposure. It was not the case that participants simply preferred English-sounding words, however, when the stimuli contained very short pauses, participants were able to learn the novel words despite the fact that they violated English phonotactics. Results suggest that prior linguistic knowledge can interfere with learners' abilities to segment words from running speech using purely statistical cues at initial exposure. 相似文献

A randomized between-group design was used to evaluate the efficacy of a video intervention to reduce post-traumatic stress disorder (PTSD) and other mental health problems, implemented prior to the forensic medical examination conducted within 72 h post-sexual assault. Participants were 140 female victims of sexual assault (68 video/72 nonvideo) aged 15 years or older. Assessments were targeted for 6 weeks (Time 1) and 6 months (Time 2) post-assault. At Time 1, the intervention was associated with lower scores on measures of PTSD and depression among women with a prior rape history relative to scores among women with a prior rape history in the standard care condition. At Time 2, depression scores were also lower among those with a prior rape history who were in the video relative to the standard care condition. Small effects indicating higher PTSD and Beck Anxiety Inventory (BAI) scores among women without a prior rape history in the video condition were observed at Time 1. Accelerated longitudinal growth curve analysis indicated a videoxprior rape history interaction for PTSD, yielding four patterns of symptom trajectory over time. Women with a prior rape history in the video condition generally maintained the lowest level of symptoms. 相似文献

The Step it UP! Game is an interdependent group reinforcement contingency based on the Good Behavior Game. We evaluated the effects of the Step it UP! Game on the number of steps taken by 3rd-grade students during physical-education (PE) classes at a local public elementary school. We divided the class into 2 teams and awarded a “Step it UP! Champ” badge to the members of the team with the highest mean step totals at the end of each game. We used a reversal design to compare the mean number of steps taken while playing the game and during regular PE classes. Overall, participants took more steps while playing the game than they did during class periods without the game. When given the opportunity to choose playing the Step it UP! Game or having regular PE class during a follow-up session, 16 of 18 participants voted to play the game. 相似文献

This study examined the disciplinary patterns and practices of 121 African American parents. Results indicated that the context of the disciplinary episode influenced how African American parents disciplined their children. Implications for counselor education and practice are discussed. 相似文献
