A rational approach to rational suicide.

Suicide is a reaction to internal and external sources of stress and the impact of life events. In the elderly these situations are prevalent in many who are not suicidal and instead choose life. They represent what may be called rational nonsuicide. They are far more frequent than rational suicide. Nevertheless, considerably more is written about rational suicide than its alternative. The reasons for this phenomenon are reviewed, and suggestions are made for a rational approach to the affirmation of life rather than its rejection, even to the very end.     

Imagery, encoding specificity, and prose recall in 6-year-old children

Partial pictures depict only selected portions of prose passages. Partial pictures hypothetically aid retention by inducing young children to generate imagery for nonpictured prose. Results from two hundred eighty-eight 6-year-old children indicated that (a) partial pictures at study facilitate recall, (b) identical study and retrieval prompts facilitate recall, and (c) imagery instructions and training do not affect retention. Partial pictures apparently help children to encode information more efficiently at study, but there is no evidence that young children generate images with the aid of the partial picture cues, nor that they have a retrieval deficit for these images as suggested by M. Ruch and J. Levin.     

The effect of standard, motivation, and strategy instructions on the facial processing accuracy of internal and external subjects

In the present study, it was hypothesized that poorer performance of externals in cognitive and interpersonal tasks also would be found in the processing of nonverbal information in the form of a facial affect recognition task. It was further hypothesized that the poorer nonverbal processing performance of externals was due to either their lower motivation or their use of less effective processing strategies. Subjects (N = 70) were divided into internal and external groups and then further subdivided into groups that received standard, motivational, or strategy instructions. Analysis of subjects' responses to the facial affect recognition task showed internals performed significantly better than externals under standard conditions. However, neither motivational nor strategy instructions improved the performance of externals. The implications for interpersonal functioning of the poorer nonverbal processing ability of extenrals was discussed from both theoretical and methodological perspectives.     

Spontaneous alternation behavior in animals: A review

Factors affecting spontaneous alternation behavior (SAB) in animals, for example, age, gender and species studied; type of apparatus and cues employed; and neuro-anatomical, neuro-chemical and motivational status of the organism, were reviewed. Despite a myriad of experiments showing interesting main effects of such variables, little research has been performed assessing the interactive affects of these factors on alternation behavior. For example, psychologists test rats in central nervous system (CNS) lesion studies, whereas psychopharmacologists tend to assess SAB in mice. Most importantly, studies have not been reported investigating the possible interactions among species, brain lesions and drugs. This is an unfortunate omission since several important alternation models include propositions relating to cholinergic and/or serotonergic coding in the hippocampus. Examination of behavioral studies revealed the primary cue for alternation among invertebrates to be body turn, whereas vertebrates rely primarily on directional and odor cues. Reference to the seeking of stimulus change remains the most compelling motivational account of why animals manifest this ubiquitious and reliable behavior pattern. This review and the unpublished studies were supported by Research Grants MH16962, MH21288, and MH36491 from the National Institute of Mental Health and the Wake Forest University Research and Publication Fund.     

CHOICE-MAKING TREATMENT OF YOUNG CHILDREN'S SEVERE BEHAVIOR PROBLEMS

The choice-making behavior of 5 young children with developmental disabilities who engaged in aberrant behavior was studied within a concurrent operants framework. Experimental analyses were conducted to identify reinforcers that maintained aberrant behavior, and functional communication training packages were implemented to teach the participants to gain reinforcement using mands. Next, a choice-making analysis, in which the participants chose one of two responses (either a mand or an alternative neutral response) to obtain different durations and qualities of reinforcement, was conducted. Finally, treatment packages involving choice making via manding were implemented to decrease inappropriate behavior and to increase mands. The results extended previous applications of choice making to severe behavior disorders and across behaviors maintained by positive and negative reinforcement.     

A comparison of multiple reinforcer assessments to identify the function of maladaptive behavior

Functional analysis results indicated that maladaptive behaviors displayed by a 25-year-old man with profound mental retardation were maintained by attention from caregivers and possibly, to a lesser degree, by access to tangible items. A concurrent-schedules procedure was then used to study the relative reinforcing value for maladaptive behavior of attention versus tangible items. Results of the concurrent-schedules assessment and subsequent functional communication training indicated that preference for attention versus access to a tangible object varied.     

The Mackworth Clock Test: a computerized version

The Mackworth Clock Test (MCT; N. H. Mackworth, 1948) was developed to evaluate vigilance in British Air Force radar technicians during World War II. Homemade versions of the MCT have since varied with respect to both the characteristics of the device and the procedures of its administration. This article is a report on a computerized version of the MCT developed by the authors to closely emulate Mackworth's test. MCT data were collected from 25 undergraduate students; their performance was found to be equivalent to Mackworth's participants' data. This is the first MCT version that has been validated against the original.     

Is Workplace Harassment Hazardous to Your Health?

We examined cross-sectional and lagged effects of sexual harassment (SH) and generalized workplace harassment (GWH) on incidence of self-reported illness, injury, or assault in a sample of over 1,500 university employees. SH and GWH, but not other job stressors, were related to increased odds of illness, injury, or assault. This was true when SH, GWH, and illness, injury, or assault were measured at the same time point, as well as when SH and GWH were measured in year prior to illness, injury, or assault.The data presented here are part of an ongoing longitudinal study of workplace harassment conducted at the Department of Psychiatry of the University of Illinois at Chicago. This research was supported by the National Institute on Alcohol Abuse and Alcoholism (grants AA09989 and AA13332). Portions of this paper were presented at the annual meeting of the Society for Industrial and Organizational Psychology, April 2004, Chicago, Illinois. The data were collected by the Survey Research Laboratory at the University of Illinois at Chicago.
