CONTINGENT REINFORCEMENT FOR CARBON MONOXIDE REDUCTION: WITHIN-SUBJECT EFFECTS OF PAY AMOUNT

The relationship between reinforcer amount and daytime smoking reduction in smokers offered money for reduced afternoon breath carbon monoxide (CO) levels was examined. Twenty-three hired regular smokers with average baseline CO levels of about 30 ppm were exposed in random order to five sliding scale payment schedules that changed daily or weekly. Money was available for afternoon CO readings between 0 and 21 ppm with pay amount inversely related to the absolute CO reading obtained. Maximum pay amount for readings below 7 ppm varied among $0, $1.50, $3, $6, and $12 per day. Contingent reinforcement promoted CO and daytime cigarette reduction within individuals with the amount of behavior change related to the amount of payment available. Average CO levels decreased from 30 to 15 ppm as a function of pay amount whereas self-reported daytime cigarettes decreased from 12 to 5 per day. Average minutes of cigarette abstinence prior to the afternoon study contact increased from 62 to 319 minutes as a function of pay amount, whereas the percentage of available money earned increased from 22% to 48%. Nontargeted evening cigarette use also decreased during periods of daytime smoking reduction. The orderly effects of this contingent reinforcement intervention on daytime smoking of regular smoker volunteers suggest that this is a sensitive model for continued evaluation of factors that influence smoking reduction and cessation.     

Fear of success as a situational phenomenon

This study was designed to determine whether different arousing situations will generate different responses in fear-of-success (FOS) and performance behavior. Female subjects were given instructions stating that the tasks they were going to complete would later be evaluated by a panel of males, females, or persons in order to determine whether the panel would select them as a potential friend, co-worker, or acquaintance. Results indicated that no significant differences in FOS were due to the different situations. However, there was evidence to conclude that level of performance behavior depends on the situation in which it is measured. Possible explanations for the failure to find FOS situational are discussed, as well as the inability to explain the significant interaction in performance behavior.     

Progressive relaxation exercises and human gastric acid output—A study using telemetric measurements

The effect of progressive muscle relaxation exercises on human gastric acid output was examined using a modification of the Heidelburg Capsule pH telemetering equipment. Fourteen healthy subjects practiced the exercises eight times before the post-exercise acidity measures were compared with control periods in the same session. No mean difference in acidity was observed. It is suggested that gastric acid secretion is more related to cognitive rather than somatic activity. Eleven of the 14 subjects reported feeling physically relaxed yet 7 of these increased acidity. Gastric acid secretion is vagally mediated through the parasympathetic nervous system. Muscle relaxation is associated with lowered sympathetic arousal. It is possible that the relaxation exercises led to increased parasympathetic arousal concomitant with sympathetic lowering since the two systems frequently act antagonistically. Progressive relaxation training does not appear to be an effective method of decreasing gastric acid output.     

An adolescent symptom checklist for juvenile deliquents

A rating instrument was developed to assess the personality functioning of problem adolescents who have a brief history of official delinquency. Subjects were 186 residents at a short-term diagnostic detention facility. The instrument that emerged from a factor analysis was tested for reliability, validity, and cross-situational generality. Two major orthogonal factors emerged, Apathy-Withdrawal (I) and Anger-Defiance (II). Each factor was found to be congruent with the corresponding dimension on behavior rating instruments that had previously yielded two orthogonal factors and that had been shown to be relevant to a large number of psychological and educational issues. Significant correlations between the factors and a series of global ratings measuring behavior and measures indicative of the frequency and seriousness of official delinquency provided further evidence of construct and discriminant validity as well as evidence of cross-setting consistency of personality functioning.

Is academic buoyancy anything more than adaptive coping?

Academic buoyancy refers to a positive, constructive, and adaptive response to the types of challenges and setbacks experienced in a typical and everyday academic setting. In this project we examined whether academic buoyancy explained any additional variance in test anxiety over and above that explained by coping. Two hundred and ninety-eight students in their final two years of compulsory schooling completed self-report measures of academic buoyancy, coping, and test anxiety. Results suggested that buoyancy was inversely related to test anxiety and unrelated to coping. With the exception of test-irrelevant thoughts, test anxiety was positively related to avoidance coping and social support. Test-irrelevant thoughts were inversely related to task focus, unrelated to social support, and positively related to avoidance. A hierarchical regression analysis showed that academic buoyancy explained a significant additional proportion of variance in test anxiety when the variance for coping had already been accounted for. These findings suggest that academic buoyancy can be considered as a distinct construct from that of adaptive coping.     

Achievement goals as mediators of the relationship between competence beliefs and test anxiety

Background. Previous work suggests that the expectation of failure is related to higher test anxiety and achievement goals grounded in a fear of failure. Aim. To test the hypothesis, based on the work of Elliot and Pekrun (2007) , that the relationship between perceived competence and test anxiety is mediated by achievement goal orientations. Sample. Self‐report data were collected from 275 students in post‐compulsory education following courses in A Level Psychology. Results. Competence beliefs were inversely related to the worry and tension components of test anxiety, both directly and indirectly through a performance‐avoidance goal orientation. A mastery‐avoidance goal orientation offered an indirect route from competence beliefs to worry only. Conclusion. These findings provide partial support for Elliot and Pekrun's (2007) model. Although significant mediating effects were found for mastery‐avoidance and performance‐avoidance goals, they were small and there may be other mechanisms to account for the relations between competence beliefs and test anxiety.     

The death of a mind: a study of Shakespeare's Richard III

Some of the most difficult aspects of our work involve our encounters with states of mind which are steeped in and spread violence. In these circumstances, we experience our best efforts to offer empathic presence and thought to avoid being assaulted and obliterated. In these instances, a figure from literature depicting the details in question may come to our aid. In the play popularly known as Richard III,William Shakespeare depicts how the state of mind which is etched by grievance and committed to revenge may impose the 'winter of (its) discontent' upon the sunny dispositions of others' healthy, integrated functioning. Shakespeare masterfully depicts Richard's cunning and malice, but he also illustrates how this vengeful state uses guile and 'changes of shape' to seduce its way past protective boundaries, utilizing the human qualities of trust, open-heartedness and longing as pathways for invasion, betrayal and emotional devastation. This paper will view excerpts of the play's text from a psychoanalytic perspective which suggests that several clear lessons about this obliterative state of mind may be gleaned: that grievance can only operate to spread grievance and destruction; that our open-hearted and trusting qualities do make us vulnerable to such invasion and betrayal, but that our humanity is also the only avenue for rescue from this plight. In addition a clear lesson is offered about the value of protected 'sanctuary', that is, mental space where our most potent tool in these circumstances, our discerning minds, might find residence.     

Depth of ankle inversion and discrimination of foot positions

Ankle inversion injuries are common, yet little is known about the error associated with different positions as inversion depth increases. In this study, absolute judgments made without feedback were used to measure discrimination of different extents of ankle inversion which arose from active movements made to physical stops by 20 self-reported right side-dominant participants. Testing was conducted over three sets of five inversion depths that were within a range of 1.4 degrees and centered around mean depths of 8,11, and 14 degrees. Discrimination of ankle inversion movements decreased linearly with depths of movement further into inversion, both within and across the sets of inversion depths. Thus, error in assessing movement position increased with inversion depth. Inversion movements that were made with the left foot were significantly better discriminated at all depths than those made with the right foot.
