Methodological and theoretical issues in neuropsychological assessment

While there are philosophical and theoretical differences between neuropsychologists and behavior therapists, it is suggested that a significant reconciliation can be achieved in regard to assessment and treatment of the brain-damaged patient. While brain damage is often viewed as an irreversible disorder, there is evidence that substantial recovery of function can occur, particularly when adequate retraining is provided. There are practical and empirical considerations that suggest that neuropsychological tests are currently the best tools available for behavioral assessment of brain-damaged patients. However, the results of these tests can be used not only diagnostically but also to identify target behavioral deficits that may be rehabilitated through systematic retraining efforts. Such rehabilitation efforts can be optimally planned, implemented, and evaluated through an alliance between the neuropsychologist, who identifies the ability and deficit pattern, and the behavior therapist, who devises and evaluates the retraining program. It is possible that the successes of behavior therapy in numerous clinical and educational applications can be repeated in the cases of brain-damaged patients. However, such success would appear to be contingent on appreciation of the high degree of specificity often seen in neurological deficit patterns and the great complexities involved in the relationships between brain function and behavior.     

Value systems and psychopathology in family therapy

Two sets of values—the continuity and the discontinuity—are readily apparent in family conflict. Pathogenic relating erupts after an impasse between the sets of values. Husband-wife conflict, parent-child conflict, and conflict between the family and neighborhood or community are described in terms of conflict in value systems. Family therapy is a method for influencing the value systems.Each of the three role functions of the family therapist—the go-between, the side-taker, and the celebrant—expresses both continuity and discontinuity values which are described. Depending on his assessment of pathogenic relating and other features of family dysfunction, the therapist selectively expresses values that serve to disrupt and then repair destructive family interaction.The process of engaging families in therapy is crucial because many families, especially those that are poor and uneducated, do not like to sit and talk about problems. Short-term therapy works best with the majority of poor, uneducated families; it even works best with middle-class families. Short-term therapy works mainly because it least violates value expectations the majority of families have about therapy.An invited presentation for the First International Congress of Family Therapy held in Tel Aviv, Israel, in February, 1976. A brief version of this paper is scheduled forPsychotherapy: Theory, Research and Practice, Vol. 15, No. 1, 1978, but due to an extraordinary delay in publication of the above-named journal, the lengthier version here may actually appear in print first. The possibility is mutually acknowledged by the editors of both journals.     

Observer orientation and actor-observer differences in attributions for failure

In a series of two experiments, male undergraduates either operated or watched another person operate a model racecar set. Instructions varied observers' expectancies about future involvement with the task. The drivers' causal attributions for their performance were compared with those of neutral observers as well as those of involved observers who anticipated running on the track. Predictions, derived from the Jones and Nisbett framework of actor/observer differences, were that actors should make more external than internal attributions and that neutral or “passive” observers should do the opposite. Moreover, the involved or “active” observer groups were expected to display attributional patterns similar to those of the actors. These predictions were confirmed. Results are discussed in terms of information and information-processing differences between groups.     

A comparison of operant licking and lever pressing in the rat

Two groups of rats were trained on a signaled, free-operant, avoidance procedure to lick or to lever press in order to avoid shock while water-deprived or satiated and, in the case of licking, while ingesting deionized water, isotonic saline, or 10% sucrose. The most effective avoidance licking occurred while the rats were water-deprived and ingesting 10% sucrose. Water deprivation level had no effect on lever pressing for shock avoidance. Two other groups of rats were operantly conditioned to lick or to lever press for food pellets while waterdeprived or satiated and, in the case of licking, while ingesting deionized water or 10% sucrose. The most effective licking for food reinforcement occurred while the rats were water-deprived and ingesting 10% sucrose. Water deprivation level had no effect on lever pressing for food reinforcement. The data indicated that effective operant licking must be supported by factors related to water regulation and taste palatability.     

Phonemic behavior of aphasic patients with posterior cerebral lesions

The investigation analyzed the phonemic paraphasic errors of 10 asphasic patients with posterior cerebral lesions. The results indicated that paraphasic speech is characterized by complex confusions, often occurring at the ends of words and often involving phonemic transpositions. Many of the unusual and unexpected phonemic errors appeared to be due to simultaneous semantic and phonologic confusions.     

Pastoral psychotherapy and the symbolic

The author points out and illustrates the interrelatedness of the capacity to think symbolically and a sense of self. Through a case study he describes the disclosure of hidden and unresolved personal concerns by symbolic references and the correspondence between personal myth and emotional concerns. A perspective of therapy is suggested—that it is a process of clarifying and demythologizing self-perceptions, conscious and unconscious, so that a person can move on to other representations of self and be liberated from restrictions imposed by undisclosed myths. Finally, the author examines what is pastoral or religious about a psychotherapeutic process and offers questions for further study.     

An hypothesis approach to the solution of anagrams

The attempts of subjects to reorganize the letters of an anagram were construed as a series of hypotheses about the correct letter order. It was predicted, consequently, that variables which reduce the number of tenable hypotheses or influence the order in which hypotheses are generated will affect problem difficulty. Five such variables, plus solution word frequency, were used to predict solution probabilities in two studies. The multiple Rs obtained were .92 and .82 and the two regression equations were effectively interchangeable. The process of anagram solution was described as entailing the retrieval of words from memory storage on the basis of letter order cues generated by the subject or, less usually, present in the anagram itself.     

Lump detection in simulated human breasts

Sixteen observers palpated silicone models of human breasts containing lumps 1.6-12.1 mm in diameter. Detectability depended on the size of the lump, producing a systematic psychometric function. In eight observers who participated in three or more sessions, performance improved with practice, with most improvement occurring within one or two 26-trial sessions. Three-week retention measures disclosed no appreciable decrease in performance, but a significant correlation was found between the number of lumps detected and duration of trial (p < .01). There was no difference in performance between four observers who used their preferred hands and four observers who used their nonpreferred hands. These data establish that examination of breast models for the detection of lumps simulating cancer is a task amenable to experimental analysis.     

A comparison of the predictive validity of typical and maximal personality measures

Most personality tests are based on concepts assessing typical performance, and tests of this sort have not been generally successful in predicting criterion behaviors with useful levels of efficiency. Ability tests, which call for maximal performance, have been much more successful as predictors of criterion outcomes. Following a model derived from ability tests, predictors requiring separate typical and maximal self-reports of emotional expressivity were compared to measures of typical and maximal emotional expression in the laboratory. For angry expression, self-reports of maximal expressivity tended to outpredict self-reports of typical expressivity for both typical and maximal laboratory measures of angry expression. Although similar trends were observed for elation, the advantage of maximal self-report measures over typical self-report measures was negligible. Results were discussed in terms of both experimental and clinical implications.
