The effects of an escape extinction procedure using protective equipment on self‐injurious behavior 下载免费PDF全文
While escape extinction has shown to be successful in reducing escape maintained self‐injurious behavior, there is limited research on the use of escape extinction with protective equipment for escape maintained self‐injurious behavior. The purpose of this investigation was to examine the effects of an escape extinction procedure paired with the application of protective equipment on the escape maintained self‐injurious behavior of an 8‐year‐old boy diagnosed with autism. Results suggested that escape extinction using protective equipment for safety is an effective approach to decrease head hitting. Rates of self‐injurious behavior during an 18‐month follow‐up were comparable to rates observed in the final intervention phase. 相似文献

Being able to recognize the faces of our friends and family members no matter where we see them represents a substantial challenge for the visual system because the retinal image of a face can be degraded by both changes in the person (age, expression, pose, hairstyle, etc.) and changes in the viewing conditions (direction and degree of illumination). Yet most of us are able to recognize familiar people effortlessly. A popular theory for how face recognition is achieved has argued that the brain stabilizes facial appearance by building average representations that enhance diagnostic features that reliably vary between people while diluting features that vary between instances of the same person. This explains why people find it easier to recognize average images of people, created by averaging multiple images of the same person together, than single instances (i.e. photographs). Although this theory is gathering momentum in the psychological and computer sciences, there is no evidence of whether this mechanism represents a unique specialization for individual recognition in humans. Here we tested two species, chimpanzees (Pan troglodytes) and rhesus monkeys (Macaca mulatta), to determine whether average images of different familiar individuals were easier to discriminate than photographs of familiar individuals. Using a two-alternative forced-choice, match-to-sample procedure, we report a behaviour response profile that suggests chimpanzees encode the faces of conspecifics differently than rhesus monkeys and in a manner similar to humans. 相似文献

According to the World Health Organization well-being has been defined as one outcome parameter indicating successful recovery from diseases. One disease causing significant psychosocial problems and distress is Gambling Disorder that is being characterized as a poorly controlled excessive engagement in gambling activities. While there are several studies investigating treatment-effects in patients with Gambling Disorder, the role of well-being as a complementary treatment outcome has not been studied so far. In our research project it was aimed to fill this gap by gathering data on changes of eudaimonic dimensions of well-being from 76 patients with Gambling Disorder before and 1 year after receiving inpatient treatment. At both waves (pretreatment and follow-up) we collected data regarding well-being (Ryff Scales of Well-being), psychopathological symptoms (SCL-9), and diagnostic criteria for Gambling Disorder (Lie/Bet-Questionnaire). We found some dimensions of well-being changing 1 year after treatment and that patients recovered from Gambling Disorder displayed significant increments in Autonomy and Environmental Mastery. In contrast, patients still meeting criteria for Gambling Disorder displayed well-being increments only in Environmental Mastery and decreases in Personal Growth and Positive Relations with Others. Only changes in Environmental Mastery and Self-Acceptance were significantly associated with decreases in psychosocial distress indicating that well-being is an additional indicator for treatment outcome. It was also intended to identify factors predicting increments in well-being. However, no relationships were found regarding demographics, clinical variables, or treatment parameters. It is proposed to acknowledge well-being as an additional indicator for treatment effects and suggested to implement therapeutic strategies for an early enhancement of well-being. 相似文献

Despite growing interest in the regionalization of immigration, comparative studies of the labor market outcomes of immigrants in traditional and non-traditional destinations remain limited in Canada. Using Atlantic Canada as a non-traditional destination and drawing data from the 2006 Census of Population, this study compares the determinants of immigrant earnings in this region with those of three major traditional destinations, Montreal, Toronto, and Vancouver (MTV). Results indicate the returns to postgraduate degrees and foreign credentials on earnings are higher in Atlantic Canada than MTV, although the costs of being visible minorities and speaking non-official language(s) at home are not statistically different between the two destinations. Results also show the earning disparities linked to employment in ethnic businesses are smaller in Atlantic Canada. This paper discusses implications of these findings for immigrant settlement policy. 相似文献

Injurious childhood experiences with one's personal father form the psychic bedrock of a negative father complex: never good enough. This complex has a part that is exciting and uses hope as its hook, and a part that disappoints and persecutes. The negative father complex can be imaged as the ghostly lover, as depicted in the fairy tale “The Singing, Springing Lark” and in Charlotte Brontë's life and famous novel, Jane Eyre. The ghostly lover holds a woman's creative energies hostage to the tantalizing possibility of being the special one who can redeem the negative masculine and win his love.To heal a complex, its contents must be personified, or imaged, so that an individual can come into conscious relationship with it. The tale of the “Singing, Springing Lark” illustrates collective roots and images of healing a wounded relationship with the masculine. Charlotte Brontë transformed her relationship with the ghostly lover through her novel Jane Eyre, with Mr. Rochester as the image of her own wounded, bewitching masculine energy. Brontë herself was subsequently able to marry, despite her father's objection, overcoming her negative father complex. The fairy tale, novel, and Brontë's life show that several attempts are usually necessary to bring the complex to light. Although consciousness seeks redemption through its pursuit of the masculine, the complex also—mysteriously—seeks its own transformation. Ego alone cannot fulfill the mission of individuation; the Self must aid the process. 相似文献

Perceived stress,recurrent pain,and aggregate salivary cortisol measures in mid‐adolescent girls and boys 下载免费PDF全文

Measures of perceived stress have been criticized for theoretical inconsistency. However, the validated pressure activation stress scale has been suggested as a theoretically sound alternative. But it is unclear how pressure and activation stress relate to objective and subjective measures including commonly used aggregate cortisol measures and health complaints respectively. Specifically, this study aimed at investigating how pressure and activation stress were related to aggregate salivary cortisol measures and recurrent pain in mid‐adolescent girls and boys. Mid‐adolescents (119 girls and 56 boys) provided self‐reports in questionnaires on activation and pressure stress and recurrent pain (headache, stomach ache, neck/shoulder and back pain). Additionally, adolescents sampled saliva during an ordinary school day: (1) immediately at awakening; (2) 30 minutes after waking up; (3) 60 minutes after waking up, and (4) at 8 p.m. These samples were analyzed for cortisol. Hierarchical regressions showed no statistically significant associations between activation and pressure stress and cortisol, neither for girls nor for boys. However, activation and pressure stress were significantly associated with recurrent pain but only for girls. The findings may relate to subjective and objective measures reflecting distinct aspects of stress‐related functioning. However, the study participants included mid‐adolescents whose bodily systems are flexible and still relatively unaffected by the strain of their daily stress perceptions. To conclude, the non‐significant relationships between activation and pressure stress and commonly used aggregate measures of cortisol adds to the understanding of how perceived stress may relate to physiological functioning in the daily life of adolescents when using such aggregate measures. 相似文献

This investigation focused on elementary-aged (first and fourth grade) children's individual preferences for narrative and expository text and perceptions of what their same-aged peers would like to read. Preferences and perceptions of text were examined through the lenses of social constructivist and engaged reading theories. The overall purpose of this study was to examine elementary students' preferences for and perceptions about narrative and expository text. This study was a systematic replication and extension of Chapman, Filipenko, McTavish, and Shapiro's (2007) research in British Columbia with first graders. Two individually administered book preference (Open and Closed) tasks and interviews were administered to 84 students. Findings revealed gender and grade level profiles in terms of preferences, perceptions, and rationales for their book choices. As expected, both first and fourth grade boys demonstrated a strong preference for expository text, however, the fourth grade boys also showed a growing preference for narrative text as well. In contrast, both first and fourth grade girls demonstrated a strong preference for both narrative and expository text. For both boys and girls, book topic and pictures/illustrations were the two top categories that drew the children's interest and resulted in the most conversations. Results are discussed in light of implications for instruction, assessment, and future research. 相似文献
