The attentional myopia model of behavioral control was tested in a study of food consumption by chronic dieters. According to the model, when individuals' attentional capacity is limited, their behavior will be disproportionately influenced by highly salient internal and external cues to the exclusion of more distal stimuli. In situations that normally feature conflicting behavioral pressures, such a state of narrowed attention is likely to result in abnormally disinhibited behavior when cues promoting action are more salient and to result in abnormally restrained behavior when inhibiting cues are more salient. In addition to supporting the predictions of the model, this study provided the first evidence for enhanced behavioral control under conditions of limited attention. Participants' responses to a thought-reporting measure also provided evidence for the role played by attentional myopia in the control of eating. Implications for a broad array of regulatory successes and failures are discussed. 相似文献

Borderline personality disorder (BPD) is often characterized by multiple low lethality suicide attempts triggered by seemingly minor incidents, and less commonly by high lethality attempts that are attributed to impulsiveness or comorbid major depression. The relationships among life events, impulsiveness, and type of suicidal behavior has hardly been studied in BPD and mood disorders. This study compared depressed attempters with and without BPD to identify specific suicide precipitants and risk factors in BPD and their relationship to severity of suicidal behavior. Attempters with comorbid BPD and major depressive disorder (MDD) had a higher number of lifetime suicide attempts; made their first attempt at a younger age; reported more interpersonal triggers; and had higher levels of lifetime aggression, hostility, and impulsivity, compared with attempters with major depression only. Environmental triggers of attempts in BPD are more likely to be interpersonal stressors. Lethality of attempts in BPD plus MDD is equal to that in MDD only, indicating that the seriousness of precipitants is unrelated to the lethality of the suicidal behavior. The differences between groups suggest that risk assessment and treatment should target both depression and personality disorder in those with combined illness. 相似文献

Adolescent bonnet macaques nursed as infants by mothers facing unpredictable requirements for food procurement (variable foraging demand, VFD) display persistent neurobiological disturbances. This study examined the long-term neurochemical and behavioral effects of adverse rearing initiated later in infancy than in previous cohorts of subjects to test the hypothesis that the timing of an early adverse experience would influence patterns of biobehavioral outcome. Cisternal cerebrospinal fluid (CSF) monoamine and corticotropin-releasing factor (CRF) concentrations were obtained from 20 bonnet macaques (11 VFD-reared and 9 normally reared controls) approximately 2 years after the end of differential rearing. VFD-reared primates displayed on multiple samplings significantly lower CSF CRF concentrations and higher CSF 5-hydroxyindoleacetic acid (5-HIAA) concentration compared to controls. In the VFD-reared, significant inverse correlations between CRF and all three monoamines were found (5-HIAA, 3-methoxy-4-hydroxyphenethyleneglycol and homovanillic acid), most prominently for 5-HIAA. In controls, but not VFD-reared subjects, CSF CRF was positively correlated with changes in "gregariousness" upon presentation of a fear stimulus. VFD-reared subjects displayed greater baseline hierarchical engagement than controls. In contrast to prior findings, in which rearing under VFD conditions at an earlier age led to increased CSF CRF compared with controls, CSF CRF was lower after later exposure to VFD rearing than in controls. Thus, the timing of exposure to VFD conditions early in life evidently determines whether CSF CRF was found to be elevated or decreased, within the context of increased serotonin metabolism, during the course of primate maturation. 相似文献

Past research has shown that strong emotional or motivational states can cause normally restrained eaters to overeat. In this article it is argued that simple cognitive load can also disinhibit eating by restrained eaters. Two studies examined this disinhibition effect. In Study 1, restrained and unrestrained eaters were given the opportunity to consume high-calorie food while performing either a high cognitive-load or low cognitive-load task. Restrained eaters consumed more food when under high cognitive load than when under low cognitive load; unrestrained eaters showed the opposite pattern. Study 2 replicated the disinhibition effect and ruled out stress, diminished awareness of food consumption, and ironic rebound as probable mediators. Results suggest that cognitive load may disinhibit consumption by preventing restrained eaters from monitoring the dietary consequences of their eating behavior. Implications for theories of self-regulation are discussed. 相似文献

This study investigated the impact of recent life events and social adjustment on suicide attempter status in 34 patients with major depression, 24 patients with borderline personality disorder, and 22 patients with co-morbid major depression and borderline personality disorder. Suicide attempters reported more recent life events and scored lower on a measure of social adjustment in their families and overall social adjustment, compared with non-attempters. Borderline disordered and borderline or depressed patients were more likely to have attempted suicide than patients with major depression only. Recent life events did not predict attempter status. Lower social adjustment in the immediate family and lower overall social adjustment were predictive of suicide attempter classification, regardless of diagnosis. Borderline disordered patients low on overall social adjustment were over 16 times more likely to have attempted suicide than patients diagnosed with major depression only. Recent life events may elevate suicide risk in groups already at high risk for suicide completion, whereas high levels of social adjustment may be protective against stress-related suicidal behavior. 相似文献

Researchers have developed an array of highly adaptable intervention packages with well‐documented efficacy for staff and teacher training. As indicated by Parsons, Rollyson, and Reid (2012) in their article on best practices in staff training, behavior analysts must use methods that are both effective and efficient given the limited resources of many human service settings (e.g., low trainer‐to‐staff ratios). The purpose of this paper is to summarize research on practical innovations for staff and teacher training, including the use of video‐based technology and self‐instruction materials that may help trainers to operate effectively despite limited time and personnel. Results are discussed in terms of the current state of the evidence for each practical innovation and considerations for integrating these strategies with best practices in staff training.
