The Effect of Server Posture on the Tips of Whites and Blacks

This study examined the effects on tips left by Black and White restaurant patrons of having a White waitress sit down or lean over at the table during the service encounter. A significant server posture by patron race interaction was obtained. Sitting at the table significantly increased the tips left by White patrons and marginally significantly decreased the tips left by Black patrons. Potential explanations for this interaction are discussed along with its practical implications.     

Assessment and treatment of problem behavior occasioned by interruption of free-operant behavior

The current study describes the assessment and treatment of the problem behavior of 3 individuals with autism for whom initial functional analysis results were inconclusive. Subsequent analyses revealed that the interruption of free-operant behavior using "do" requests (Study 1) as well as "do" and "don't" requests (Study 2) occasioned problem behavior. Initially, treatment involved differential and noncontingent reinforcement without interruption. To make the intervention more sustainable in the natural environment (where interruptions are unavoidable), a two-component multiple-schedule arrangement was used to progressively increase the period of time in which ongoing activities would be interrupted. During generalization sessions, the intervention was applied across a variety of contexts and therapists.     

The assessment of alexithymia in medical settings: implications for understanding and treating health problems

The construct of alexithymia encompasses the characteristics of difficulty identifying feelings, difficulty describing feelings, externally oriented thinking, and a limited imaginal capacity. These characteristics are thought to reflect deficits in the cognitive processing and regulation of emotions and to contribute to the onset or maintenance of several medical and psychiatric disorders. In this article, we review recent methods for assessing alexithymia and examine how assessing alexithymia can inform clinical practice. Alexithymia is associated with heightened physiological arousal, the tendency to notice and report physical symptoms, and unhealthy compulsive behaviors. Alexithymic patients may respond poorly to psychological treatments, although perhaps not to cognitive-behavioral techniques, and it is unclear whether alexithymia can be improved through treatment. Interpretive problems regarding alexithymia include its overlap with other traits, whether it is secondary to illness or trauma, the possibility of subtypes, and low correlations among multiple measures. Nonetheless, we encourage the assessment of alexithymia in applied settings.     

Aging and a benefit of distractibility

Under instructions to ignore distraction, younger and older adults read passages with interspersed distracting words. Some of the distractors served as solutions to a subsequent set of verbal problems in which three weakly related words could be related by retrieving a missing fourth word (i.e., the Remote Associates Test [RAT]; Mednick, 1962). Older adults showed significant priming from the distraction, whereas younger adults did not. In this study, we present a case in which age-related reductions in attentional control over information that was not initially relevant can actually lead to superior performance for older adults.

Stress administered prior to encoding impairs neutral but enhances emotional long-term episodic memories

Stressful events frequently comprise both neutral and emotionally arousing information, yet the impact of stress on emotional and neutral events is still not fully understood. The hippocampus and frontal cortex have dense concentrations of receptors for stress hormones, such as cortisol, which at high levels can impair performance on hippocampally dependent memory tasks. Yet, the same stress hormones can facilitate memory for emotional information, which involves interactions between the hippocampus and amygdala. Here, we induced psychosocial stress prior to encoding and examined its long-term effects on memory for emotional and neutral episodes. The stress manipulation disrupted long-term memory for a neutral episode, but facilitated long-term memory for an equivalent emotional episode compared with a control condition. The stress manipulation also increased salivary cortisol, catecholamines as indicated by the presence of alpha-amylase, heart rate, and subjectively reported stress. Stressed subjects reported more false memories than nonstressed control subjects, and these false memories correlated positively with cortisol levels, providing evidence for a relationship between stress and false memory formation. Our results demonstrate that stress, when administered prior to encoding, produces different patterns of long-term remembering for neutral and emotional episodes. These differences likely emerge from differential actions of stress hormones on memory-relevant regions of the brain.     

Effectiveness of Dialectical Behavior Therapy in a Community Mental Health Center

Dialectical behavior therapy (DBT) has been shown to be effective in randomized controlled trials with women with borderline personality disorder and histories of chronic self-inflicted injury including suicide attempts. The present study is a pre-post replication of a comprehensive DBT program in a community mental health center for individuals who chronically injure themselves and/or have experienced multiple treatment failures. Twenty-four subjects were given the Treatment History Interview to obtain information regarding medically treated self-inflicted injuries and the use of crisis services. After 1 year of treatment, DBT showed a significant reduction in the number and severity of self-inflicted injuries, psychiatric-related emergency room visits, psychiatric inpatient admissions and days, and the number of crisis treatment systems engaged. Results are compared to benchmarks from 3 other clinical trials of DBT. While this pre-post comparison has threats to internal validity, it supports the feasibility of DBT when fully implemented in a community mental health clinic.     

Academia, Aristotle, and the Public Sphere – Stewardship Challenges to Schools of Business

In this paper we suggest that the ethical duties of business schools can be understood as representing stewardship in the Aristotelian tradition. In Introduction section we briefly explain the nature of ethical stewardship as a moral guideline for organizations in examining their duties to society. Ethical Stewardship section presents six ethical duties of business schools that are owed to four distinct stakeholders, and includes examples of each of those duties. Utilizing this Framework section identifies how this framework of duties can be used in the process of self-examination and transformation within business schools. Why It Matters section concludes by explaining why the process of examining ethical duties at business schools is vitally important for both business schools and the larger communities that they serve.

Investigating the dynamics of affect: Psychological mechanisms of affective habituation to pleasurable stimuli

Affective habituation (i.e., reductions in stimulus-evoked affective reactions as a result of previous exposure) may serve a functional purpose. However, little is know about the psychological mechanisms underlying this process. To elucidate the characteristics of affective habituation, two experiments that examined affective reactions to repeated exposures of pleasurable stimuli were conducted. Results of these experiments indicated that habituation trajectories are characterized by linear decreases in affect. Results also demonstrated that habituation can be slowed by the introduction of novel stimuli (i.e., “novelty effects”), effects that are dimensional (rather than taxonic) in nature. Experiment 2 demonstrated that habituation is mediated by conceptual rather than perceptual processes. Depressed and anhedonic individuals were not more susceptible to habituation in either experiment. The current findings and previous theorizing suggest that habituation may be an important component of an adaptive affective processing system that promotes effective responses to salient stimuli and prevents compulsive reward-seeking behavior.

Use of an analog task to study effects of diazepam on taste perception, consummatory behaviors, and risk taking in a social context

In the present study, the authors examined the effects of diazepam (Valium) on various physical, social, and emotional variables within the framework of a task designed to test risk-taking behavior. Participants received either 10 mg of diazepam or a placebo. After the participants tasted strong-flavored liquids, they were able to engage in a risky behavior (i.e., drinking from a confederate's "used" water bottle). Half the participants received additional verbal pressure to drink from the bottle. The authors expected that diazepam would increase health-risk behavior, but the results were inconsistent with that prediction. The second goal of the experiment was to explore diazepam's effects on arousal, mood, social anxiety, and taste. Diazepam users exhibited differences in taste perception and social anxiety, which might in part explain the health-risk results.
