A technique for controlling behavior in natural life settings

A behavior control technique is presented, consisting primarily of having a patient give up some portion of his reinforcers (usually money) with the understanding that he must behave in therapeutically prescribed ways in his natural environment to re-earn the reinforcers. The critical features and requirements of the technique are discussed, various applications are suggested, and implications for research are drawn.     

Psychojargon in the psycholegal report: Ratings by judges,psychiatrists, and psychologists

Questionnaires designed to measure the perceived value of technical terminology for psycholegal reports were completed by 67 judges, 78 forensic psychiatrists, and 126 forensic psychologists. Judges were asked for ratings of the degree to which each term aids their understanding, and clinicians were asked for ratings of the likelihood that they would use each term in a report for the court. Rank-ordered ratings of the 45 terms were highly correlated among the three respondent groups, suggesting that forensic clinicians are generally aware of the problem of using incomprehensible psychojargon. Empirical ratings can be helpful in distinguishing between comprehensible and incomprehensible psychojargon for psycholegal use.     

Psychological re-evaluations: A survey of practices and perceptions of school psychologists

The practice of psychologically re-evaluating students receiving special education services has been mandated by P.L. 94–142 and further operationalized by state departments of education. Intuitively, such a requirement appears sound, for psychologists occasionally make mistakes, children change over time, and efficacy of special education services is variable. Yet given the other mandated practices, such as yearly IEP updates, and the fact that many school psychologists spend a majority of their time testing, we wondered how important three-year psychological re-evaluations are considered by school psychologists. In the present study 40 psychologists across four states were surveyed concerning their perceptions and practices regarding re-evaluations. The psychologists' responses to a 16-item questionnaire indicated that re-evaluations comprised a substantial portion of their evaluations, involved a considerable amount of time, and were perceived as an important check on a child's diagnosis and placement. Re-evaluations and initial evaluations were described as involving nearly identical tests and related activities.     

Problem-Solving Appraisal and the Prediction of Depression During Pregnancy and in the Postpartum Period

Based on the presumed mood-regulatory properties of the problem orientation component delineated in the social problem-solving model, a positive problem orientation was predicted to influence ongoing levels of positive and negative affect during pregnancy. Higher levels of positive affect and lower levels of negative affect would then in turn predict depression during pregnancy and in the postpartum period. This hypothesis was tested in 100 women. Path analyses supported the predicted relation of the problem orientation components to trait affectivity, and indirectly to peripartum and postpartum depression. Trait negative and positive affectivity was also associated with peripartum depression, and indirectly with postpartum depression, as expected. Implications for the integrated social problem-solving model are discussed. Recommendations for assessment and counseling interventions with expectant women are offered.     

Changes in Behaviour and Body Weight Following a Single or Double Social Defeat in Rats

In a series of experiments, the consequences of a single and double social conflict on various behaviours and body weight in rats were studied. Animals were subjected to social defeat by placing them into the territory of an aggressive male conspecific for one hour, either once, or twice at the same time on two consecutive days. To assess the consequences of social defeat, three experiments were performed with independent groups of rats. In the first experiment, an open field test was performed two days after the last conflict. Locomotor activity was strongly reduced after social defeat. There were no differences between the single and double defeat group. To assess the effects of social defeat on subsequent social behaviour, a second experiment was performed in which experimental animals were confronted with an unfamiliar non-aggressive rat two days after a single or double conflict. Social defeat resulted in a reduction of social contact with the unfamiliar conspecific. There was no difference between the single and double conflict group. In the third experiment, the effects of social conflict on food intake, body weight and saccharine preference were measured. Food intake was not affected after a single conflict, but in the double conflict group food intake was decreased for several days. Body weight gain was decreased after both single and double social defeat. The decrease was stronger in the double conflict group. Water intake and saccharine preference were not significantly affected. This study revealed that social defeat in rats causes pronounced changes in various behaviours and body weight. Different aspects of behaviour are differentially affected by defeat with respect to the magnitude and time course of the changes induced. Moreover, different behavioural parameters are differentially sensitive to repetition of the stressor.     

Self-appraised problem-solving skills and the prediction of secondary complications among persons with spinal cord injuries

Secondary complications following spinal cord injury (SCI) include decubitus ulcers and recurrent urinary tract infections. These conditions can significantly impair quality of life and prove life-threatening; it is also believed that these conditions are mediated by behavioral pathways. According to the social problem-solving model, persons who report effective problem-solving skills should be capable of adhering to long-term therapeutic regimens of self-care necessary to prevent these complications. We tested this assumption in the present study. Discriminant function analyses revealed self-appraised skills in approaching and defining problems contributed to the prediction of secondary complications among 53 persons with SCI. Results are discussed in light of the social problem-solving model, and the utility of problem-solving interventions in rehabilitation is explored.     

Personality correlates of self-appraised problem solving abilities

We examined the relations between the components of self-appraised problem solving abilities and personality constructs measured by a popular instrument. Results indicated that the Approach-Avoidance and Problem-Solving Confidence factors of the Problem Solving Inventory (PSI; Heppner, 1988) were significantly associated with the judging, perceiving, and feeling scales of the Myers-Briggs Type Indicator (Myers & McCaulley, 1985) among 112 undergraduates. Our results elucidate the relations between problem-solving appraisal, emotional predispositions, Willfulness, and preferences for structure. Implications for theoretical models of social problem solving and counselling interventions are discussed.     

The neuropsychological profile in unipolar depression

There is a wealth of empirical data pertaining to the issue of neuropsychological impairment in depression. However, a coherent and comprehensive framework for understanding the disorder remains elusive. This review will briefly consider some of the important issues on which recent research has focused. It would be premature to derive firm conclusions in an area characterized by considerable confusion, so the aim of this review is to highlight the key areas that must be addressed. Three distinct questions are considered. The first concerns the neuropsychological specificity of the deficits associated with depression; whether they represent selective deficits or a more general profile of impairment. The second question is to determine how cognitive deficits might relate to clinical and demographic factors, including symptom severity, hospitalization, medication and ageing. Finally, a comprehensive theory of depression must also relate impairments to neuropathology, and evidence is now available from imaging studies that have attempted to elucidate neural substrates of neuropsychological deficits.     

Interference of Sentence and Picture Contexts on Learning Prepositions

The effects of extra stimulus cues, such as pictures and sentences, on learning of preposition words were examined in two experiments. A one-way repeated-measures design was applied in the study. The results show that both sentences and pictures interfered with and blocked the learning of these context-dependent words in the simultaneous presentations. The superiority of feedback presentations over simultaneous presentations indicate that feedback techniques neutralize the blocking effect. More interestingly, however, the prepositions were learned more quickly in the absence of any context cues and this suggested that it is better to teach basic preposition words either by the presentation of them alone or if extra stimulus cues are to be used they should be presented as feedback.
