II—Jerrold Levinson

ABSTRACT Being an aesthetic realist is hard work. Derek Matravers has raised a number of concerns for the brand of aesthetic realism that I have defended in the past, and that I continue to defend, albeit with modification. Much turns on the nature of aesthetic properties, and on the reasons for acknowledging their existence. I here try to provide further illumination on both scores, suggesting in particular that many aesthetic properties can be viewed as manifest higher-order ways of appearing. Toward the end of my discussion the question of whether or not aesthetic properties are response-dependent is addressed, and I offer the tentative conclusion that some are, and some are not.     

Dual and non-dual ontology in Satre and Mahāyāna Buddhism

The role of emotion control and emotional rumination in stress management training

The present paper reports on three outcome studies evaluating the effectiveness of a new stress management training program. In contrast to conventional stress management, which tends to emphasize life-events, the symptoms of stress and relaxation, the new program is based on emotional rumination, emotion control, and attention control. The training developed from a series of experimental studies on the role of emotional inhibition and rumination in prolonging physiological recovery from stress, and the findings reported here were obtained from a series of applied studies involving police officers from a police force in the North of England. The first two studies employed both self-reported and objective measures of change to demonstrate that the training produced significant increases in job satisfaction and reduced absenteeism, while the results of the final study showed that the benefits of the program were enhanced by follow-up training.     

Psychopharmacological treatment of unipolar depression within the elderly: A discussion paper

Depressive disorders are known to affect all aspects of a person's functioning and are often associated with significant psychosocial impairment. What is unclear is whether these psychosocial issues are consequences or causes of depression; what is known is that these problems do not disappear when the biological symptoms resolve. Existing data on the treatment course and outcome of depression are not generally considered as representative of the older depressed person. Discussion will take place as to whether later life depression should be conceptualized not as a categorical disorder, but as a geriatric syndrome, with multiple aetiologies requiring a combination of treatment interventions. There is general consensus that when intensive psychotherapy is directed towards appropriate patients, geriatric clientele are as able to deal with the viscitudes of intensive therapy as well as any age group. An examination will be undertaken regarding the utilization of psychotherapeutic interventions, namely psychodynamic, interpersonal and cognitive behavioural. Comparative studies have demonstrated all three to be effective, particularly in the treatment of depression. There is a great need for further understanding and research into the appropriateness and efficacy of an integration of psychotherapeutic and pharmacotherapeutic intervention in the treatment of depression, particularly within the elderly. A tantalizing array of research possibilities emerge. If we accept that unipolar depression is a bio-psychosocial phenomena, then we need to understand more about which psychopharmacological treatment paradigms need to be employed, and that perhaps the way forward inclines towards pragmatic integrationism rather than puritanist intervention.     

Gerbils in space: performance on the 17-arm radial maze.

In Experiment 1 six hungry gerbils received six trials per day on a 17-arm radial maze. During each trial the subjects were allowed to choose freely among the arms, each of which contained a food pellet, until each arm had been visited once or until eight minutes had elapsed. An error was recorded when the subject entered a previously visited arm. The gerbils quickly learned not to re-enter previously visited arms and generally made errors on fewer than 15% of entries, performance comparable to that of the rat and superior to that of other species tested in the radial arm maze. The intertrial-interval duration did not affect accuracy of arm choices during acquisition but did influence asymptotic accuracy. Accuracy did not change systematically over the six trials. A high proportion of arm entries were to nearby arms. Errors occurred most often towards the end of a trial. Odor cues were not important. When the number of trials per day was reduced from six to one, accuracy deteriorated slightly. In Experiment 2 neither the transposition of extramaze cues nor the placement of the maze in a different room had large disruptive effects on accuracy. In Experiment 3 the addition of three explicit intramaze brightness cues aided accuracy, perhaps by permitting the subjects to decompose the large maze into three smaller mazes, although there was no direct evidence that this was the case. Implications of a number of these results for models of spatial maze performance were discussed.

Errorless discrimination established by differential autoshaping

In Experiment I, pigeons exposed to a differential autoshaping procedure pecked a key in the presence of the stimulus associated with reinforcement but did not peck, or pecked infrequently, in the presence of the stimulus associated with nonreinforcement. In Experiment II, pigeons were exposed to a differential autoshaping procedure in which one stimulus was associated with reinforcement and two stimuli were associated with nonreinforcement. The birds initially responded in the presence of one stimulus associated with nonreinforcement but never responded in the presence of the second stimulus associated with nonreinforcement. They were subsequently exposed to an autoshaping procedure in which reinforcement followed both these stimuli. The number of stimulus-reinforcement pairings required to establish pecking in the presence of the stimulus during which responses had not previously occurred suggested that such stimuli are inhibitory. These findings have implications for autoshaping, errorless discrimination, inhibition, and theories of discrimination byproducts.     

Attention in the pigeon: a reevaluation

During training sessions, pigeons were successively exposed to compounds consisting of a white triangle on a red background and a white circle on a green background. Key pecking intermittently produced grain reinforcers in the presence of one form-color compound. Once key pecking was confined to the compound associated with reinforcement, the elements—red, green, triangle, and circle—were presented during a test in which no reinforcement was available. Each bird pecked nearly exclusively in the presence of the color previously associated with reinforcement, a result that might be interpreted as indicating that the subjects had attended to color, but not form during training. Pecking was next reinforced when either the triangle or the circle was present. Pecking in the presence of the form previously associated with reinforcement was acquired more rapidly. This result suggests that the birds had learned about the forms during training, and that conclusions about attention based on the lack of differential pecking in the nonreinforcement test may not be appropriate.
