Previous research has described the significant role that social interaction plays in both the acquisition and use of speech by parrots. The current study analyzed the speech of one home-raised African Grey parrot (Psittacus erithacus erithacus) across three different social contexts: owner interacting with parrot in the same room, owner and parrot interacting out of view in adjacent rooms, and parrot home alone. The purpose was to determine the extent to which the subject’s speech reflected an understanding of the contextual substitutability (e.g., the word street can be substituted in context for the word road) of the vocalizations that comprised the units in her repertoire (i.e., global co-occurrence of repertoire units; Burgess in Behav Res Methods Instrum Comput 30:188–198, 1998; Lund and Burgess in Behav Res Methods Instrum Comput 28:203–208, 1996). This was accomplished via the human language model hyperspace analog to language (HAL). HAL is contextually driven and bootstraps language “rules” from input without human intervention. Because HAL does not require human tutelage, it provided an objective measure to empirically examine the parrot’s vocalizations. Results indicated that the subject’s vocalization patterns did contain global co-occurrence. The presence of this quality in this nonhuman’s speech may be strongly indicative of higher-order cognitive skills. 相似文献

Suicide research remains fraught with ethical and methodological issues, including researchers’ reservations about conducting intensive suicide research protocols due to potential iatrogenic effects and liability concerns. Such issues significantly impede scientific inquiry related to suicide. To date, no research has explored potential iatrogenic effects of intensive, nontreatment suicide research among Veterans. This study aimed to fill this gap. It was hypothesized that participation in suicide‐specific protocols would not significantly increase risk among Veterans. Veterans completed self‐reports, structured interviews, and rigorous suicide‐specific tasks (Study A, N = 34; Study B, N = 18; Study C, N = 119). Findings indicated there were no significant differences in pre‐ and postassessment suicide risk variables (all ps > .05). Estimated mean change for “urge to harm self” was ?0.24 (95% confidence interval [CI]: ?0.60, 0.13), ?0.28 (CI: ?0.56, 0.01), and ?0.01 (CI: ?0.09, 0.07) and “intent to harm self” was ?0.18 (95% CI: ?0.45, 0.10), 0 (CI: ?0.17, 0.17), and 0.01 (CI: ?0.04, 0.06) for Studies A, B, and C, respectively. Results indicated the respective protocols did not produce iatrogenic effects. The current findings are discussed with attention to safety‐monitoring techniques that may reduce iatrogenic effects and considerations for future researchers. 相似文献

We explored 10 novice school counselors’ experiences working to close the achievement gap with low-income adolescents through interpretative phenomenological analysis. Results suggest that school counselors experienced their role in closing the achievement gap with low-income adolescents as one of (a) systemic discouragement, (b) interactions with students’ home environment, and (c) parallel process advocacy. Implications for school counselors, counselor educators, and future research are included. 相似文献

Health locus of control has been shown to influence how individuals approach their health and health-related decisions. The
present study examined the variables predictive of older adults’ health locus of control. A total of 261 adults aged 54–84 years
completed a questionnaire about their health, approach to health, and background information about themselves. The results
revealed that demographic indicators, health-related variables, and psychological variables—particularly health risk tolerance,
future time perspective, health self-efficacy, and emotional instability—were related to older adults’ health locus of control.
Findings have implications for programs aimed at modifying older adults’ health locus of control. 相似文献

The provision of information appears to be an important property of self-esteem as evidenced by previous research concerning the status-tracking and status-signaling models of self-esteem. The present studies examine whether there is an implicit theory of self-esteem that leads individuals to assume targets with higher levels of self-esteem possess more desirable characteristics than those with lower levels of self-esteem. Across 6 studies, targets with ostensibly higher levels of self-esteem were generally rated as more attractive and as more desirable relationship partners than those with lower levels of self- esteem. It is important to note, however, that this general trend did not consistently emerge for female targets. Rather, female targets with high self-esteem were often evaluated less positively than those with more moderate levels of self-esteem. The present findings are discussed in the context of an extended informational model of self-esteem consisting of both the status-tracking and status-signaling properties of self-esteem. 相似文献

Functional analysis (FA) methodology is the most precise method for identifying variables that maintain problem behavior. Occasionally, however, results of an FA may be influenced by idiosyncratic sensitivity to aspects of the assessment conditions. For example, data from several studies suggest that inclusion of a tangible condition during an FA may be prone to a false-positive outcome, although the extent to which tangible reinforcement routinely produces such outcomes is unknown. We examined susceptibility to tangible reinforcement by determining whether a new response was acquired more readily when exposed to a tangible contingency relative to others commonly used in an FA (Study 1), and whether problem behavior known not to have a social function nevertheless emerged when exposed to tangible reinforcement (Study 2). Results indicated that inclusion of items in the tangible condition should be done with care and that selection should be based on those items typically found in the individual's environment. 相似文献

This study used daily diary data to model trait and state Positive Affect (PA) and Negative Affect (NA) using the Positive and Negative Affect Schedule (PANAS; Watson, Clark, & Tellegen, 1988). Data were collected from 364 college students over five days. Intraclass correlation coefficients suggested approximately equal amounts of variability at the trait and state levels. Multilevel factor analysis revealed that the model specifying two correlated factors (PA, NA) and correlated uniqueness terms among redundant items provided the best fit. Trait and state PA and NA were generally associated with stress, anxiety, depression, and three types of self-esteem (performance, academic, social). The coefficients describing these relationships differed somewhat, suggesting that trait and state measurement may have different predictive utility. 相似文献

Using seven waves of data, collected twice a year from the 8th through the 11th grades in a low-resource community in Cape Town, South Africa, we aimed to describe the developmental trends in three specific leisure experiences (leisure boredom, new leisure interests, and healthy leisure) and substance use (cigarettes, alcohol, and marijuana) behaviors and to investigate the ways in which changes in leisure experiences predict changes in substance use behaviors over time. Results indicated that adolescents' substance use increased significantly across adolescence, but that leisure experiences remained fairly stable over time. We also found that adolescent leisure experiences predicted baseline substance use and that changes in leisure experiences predicted changes in substance use behaviors over time, with leisure boredom emerging as the most consistent and strongest predictor of alcohol, cigarette, and marijuana use. Implications for interventions that target time use and leisure experiences are discussed. 相似文献

Disorganized/controlling attachment in preschool has been found to be associated with maternal and child maladjustment, making it of keen interest in the study of psychopathology. Additional work is needed, however, to better understand disorganized/controlling attachment occurring as early as age three. The primary aims of this study were to evaluate risk factors and outcomes associated with disorganized/controlling behavior at age three and to evaluate the risk factors and outcomes differentiating the four subtypes of disorganized/controlling attachment. Analyses were conducted with the first two phases of the NICHD Study of Early Child Care and Youth Development, a prospective study of 1,364 children from birth. At 36 months of age, across the attachment-relevant domains of maternal well-being, mother-child interactions, and child social adaptation, the disorganized/controlling group evidenced the most maladaptive patterns in comparison to both secure and insecure-organized groups. At 54 months of age, the disorganized/controlling group displayed the highest levels of internalizing and externalizing behavior problems, as rated by mothers and teachers, and the lowest quality relationships with teachers. Significant differences found among the disorganized/controlling subtypes indicated that the behaviorally disorganized and controlling-punitive subtypes had more maladaptive patterns across variables than did the controlling-caregiving and controlling-mixed subtypes. 相似文献

The present investigation examined the mediating role of distress tolerance in the association between impulsivity and alcohol use coping motives among trauma-exposed individuals. Participants were 86 adults (64.3% women; M(age) = 23.4, SD = 9.3) who met the DSM-IV-TR posttraumatic stress disorder (PTSD) criterion A for at least one traumatic life event and endorsed alcohol use in the past month. Distress tolerance at least partially mediated the association between impulsivity and alcohol use coping motives, after controlling for the variance explained by PTSD symptom severity and alcohol use problems. Clinical implications and future directions related to this line of inquiry are presented and discussed. 相似文献
