Situation-Behavior Profiles as a Locus of Consistency in Personality

Traditional approaches have long considered situations as "noise" or "error" that obscures the consistency of personality and its invariance. Therefore, it has been customary to average the individual's behavior on any given dimension (e.g., conscientiousness) across different situations. Contradicting this assumption and practice, recent studies have demonstrated that by incorporating the situation into the search for consistency, a new locus of stability is found. Namely, people are characterized not only by stable individual differences in their overall levels of behavior, but also by distinctive and stable patterns of situation-behavior relations (e.g., she does X when A but Y when B ). These if . . . then . . . profiles constitute behavioral "signatures" that provide potential windows into the individual's underlying dynamics. Processing models that can account for such signatures provide a new route for studying personality types in terms of their shared dynamics and characteristic defining profiles.     

A Brief History of Jungian Splits in the United Kingdom

The institutionalizing of analytical psychology in the United Kingdom has its origins in the Analytical Psychology Club founded on 15 September 1922. It became increasingly apparent that professionalization of the Jungian movement was essential and this led to the formation of the Society of Analytical Psychology in 1946. This was followed in 1951 by the founding of the British Association of Psychotherapists. The Association of Jungian Analysts split off from the Society of Analytical Psychology in 1975–6, and this was followed in 1982 by the split between the Association of Jungian Analysts and the Independent Group of Analytical Psychologists. The Berlin Congress of 1986 saw the beginnings of a liaison body for the four London societies, which came to be called the Umbrella Group. This has organized joint conferences and workshops, but the split in 1992 between the United Kingdom Council for Psychotherapy and the British Confederation of Psychotherapists has posed a new threat to the growing harmony between the London societies. In the face of this threat, the Umbrella Group has not been able to articulate a common policy and strategy about the Jungian presence in the United Kingdom.     

The use of expectancy theory in the explanation of turnover in ROTC

A questionnaire was administered to 142 mate students who were enrolled in ROTC and 18 male students who had dropped out of ROTC. Several months later seven of the above 142 subjects dropped out of ROTC. A ratio expectancy theory model was developed from the questionnaire as an operational definition of motivation to remain in ROTC. The results indicated that the 25 dropouts had a significantly lower (p < .001) score on this motivational measure than the 135 subjects who were still enrolled in ROTC, and also that these latter subjects were as strongly attracted to a civilian job as they were to an Army job. The implications of these findings relative to the ability of the Army to attract career officers were discussed.     

The interaction of memories in the rat: Effects on short-term retention performance

In four experiments, rats were tested for short-term retention of a target spatial location either with or without prior exposures to alternate spatial locations in a T-maze. In all cases, exposure to alternate locations prior to exposure to the target location impaired retention of the target. This impairment increased as the number of exposures to the alternate location was increased, and the impairment decreased as the interval between alternate and target exposures was increased. In no case was the magnitude of the impairment found to increase as the retention interval was lengthened.     

Language and speech recovery in a case of viral encephalitis

The speech and language recovery course of a 47-year-old man with viral encephalitis is described. Over a 3-month period, the patient was evaluated six times using the same selected battery of tests. Results show that viral encephalitis can deleteriously affect communicative performance and that improvement in medical status is accompanied by rapid and dramatic gains on most standard speech and language measures. For this case changes appeared related to improved auditory attention and retention, increased efficiency in word retrieval, and improved mental status.     

Food-searching behavior of cats in a multiple-choice elimination problem

Twelve cats were individually exposed to a four-point elimination problem for 50 consecutive days. The problem for the animals consisted of choosing a series of different points where they found, and were allowed to eat, a piece of meat, without returning to any previously visited point. The order of elimination was not controlled in any way by the experimenter. Results indicated that cats were able to solve this problem. All subjects showed a strong tendency to make successive runs toward points situated as far apart as possible. Moreover, a relation was shown between performance and the tendency to follow this high divergence principle. This result is discussed in terms of subjects' ability to process information about the spatial characteristics of the experimental situation. This ability might in fact be related to the behavioral plasticity of animals in spatial problems according to the difficulty of the task.     

A study of spelling in aphasia

To secure systematic information on spelling abilities following damage to the dominant hemisphere, a test probing performance in three modalities of response was administered to a group of aphasic patients. Except for a predictable deficit among anterior aphasics in oral spelling, anterior and posterior aphasics exhibited comparable performances on the measures of spelling. However, anterior and posterior aphasics differed from one another on the kinds of words they most accurately spelled, the errors they were prone to make, and certain strategies which they characteristically adopted. These results suggest two alternative approaches to spelling: one approach, common in posterior aphasics, entails choosing letter combinations on the basis of their customary sounds; a second approach, common among anterior aphasics, appears to rely on a partially preserved image of the word's appearance.     

Group differences in intelligence and speed of information-processing

Three samples of different levels of mental ability, but each of average or above- average intelligence, were administered a battery of reaction time test which measure the speed with which persons can execute various elementary cognitive processes. Discriminant analyses revealed significant differences between the groups in reaction times and intraindividual standard deviations, and univariate analyses indicated that higher ability groups tended to obtain significantly faster mean reaction times and to show significantly less intraindividual variability than lower ability groups. Groups which differed the most in mental ability differed to the greatest extent on the more complex reaction time tests but this pattern was reversed for groups which were relatively close in mean IQ. Generally, the results support the hypothesis that speed- of-processing is an important factor unferlying intelligence, but a number of puzzling findings indicate the need for continued research in this area.     

Sex differences in realization of individual potential for achievement

Data from 4035 participants in Project TALENT were analyzed to examine the extent to which known sex differences in achievement held up when early potential for achievement was contolled. Original TALENT data, consisting of information on socioeconomic background, cognitive abilities, and educational and occupational aspirations, were collected in 1960 when members of the study sample were in Grade 9. Follow-up surveys measuring participants' educational and occupational attainment were conducted at 1, 5, and 11 years after the date of participants' expected graduation from high school. Women had higher high school grades and scored higher on a composite of academic ability tests taken in Grade 9 than did men. However, by 11 years after high school, men had acquired more education and were earning more money on the job. Sex differences in realization of achievement potential were found across all socioeconomic levels. At least part of the reason behind women's relative failure to translate potential into achievement may lie in the greater conflict, for women, between the roles of spouse/parent and the roles of student/worker: variables measuring the onset, duration, and extent of family-related commitments were more strongly related to female than to male realization of potential. Sex differences in achievement grew larger between the 5- and 11-year follow-ups as a greater proportion of women in the study sample became wives and mothers. The widening of the sex gap in achievement during this period was particularly pronounced among the subgroup of individuals who were in the top quartile of potential in Grade 9.     

Electroencephalographic and dichotic indices of cerebral laterality in stutterers

To test the hypothesis that stuttering is the product of faulty cerebral laterality four experiments were performed on each of five adult stutterers and five fluent speakers. These tests were: (1) dichotic listening with consonant-vowel pairs, (2) alpha recording over both hemispheres during the performance of cognitive tasks intended to engage preferentially the left or right hemispheres, (3) contingent negative variation with either an articulatory or bilaterally symmetrical response, and (4) readiness potential with the same responses. The results fail to disconfirm the null hypothesis regarding stutterers and their fluent peers. All subjects showed consistent patterns of cerebral laterality indicative of localization of speech function in the left hemisphere. Suggestions are made regarding a possible contribution of deficient sensorimotor integration in stuttering.     

The role of cue additivity in salience in taste aversion conditioning

In toxiphobia conditioning certain cues are more easily associated with malaise (i.e., more salient) than others. The present experiments show that cue additivity can account for previously found differences in salience of certain fluids. The relative salience of saccharin, saline and casein hydrolysate was tested in normal rats and in animals rendered anosmic by treatment of their nasal passages with zinc sulphate. The normally more salient casein was reduced in salience to the same level as saccharin and saline in the anosmic animals, while anosmia did not affect the relative salience of saccharin and saline. A second study tested the cue properties of vanilla, a fluid of very low salience. Anosmic animals could not show a conditioned aversion to vanilla. Normal animals readily learned the aversion but could not show it following a later anosmia treatment. Anosmia did not disrupt a saccharin aversion previously conditioned in normal animals. The data show that some of the “tastes” used in toxiphobia conditioning have olfactory components, and some are purely olfactory. Further, olfactory cues can summate with taste cues to form a more salient stimulus.     

Distraction effects in tasks of varying difficulty: Methodological issues in measuring development of distractibility

Effects of distraction on 5- and 8-year-old children's performance on a short-term memory task were examined. Tasks at three difficulty levels were employed to determine whether a floor effect could account for the lack of an age difference reported in an earlier study. A floor effect does not appear to be a key factor; the absolute amount of performance decrement was roughly equal for the two ages here regardless of task difficulty, and performance was well above chance under all conditions. The children adapted somewhat to the presence of distraction as shown in greater performance impairment for the first trial under distraction than for remaining trials. Use of a proportional, rather than an absolute, decrement index was considered, and the relevance of the present data to this issue was discussed.     

Contingent reinforcement of lowered blood-alcohol levels in an outpatient chronic alcoholic

Recently. the proposition that alcohol abuse is an operant behavior and thus functionally related to its consequences has been investigated under experimental conditions. In controlled laboratory settings, in which inpatient chronic alcoholics are allowed access to alcoholic beverages, alcohol consumption has been markedly altered via operant strategies. Monetary rewards (Cohen et al., 1971), the opportunity to participate in an enriched environment (Cohen et al., 1971). and visits to a girlfriend (Bigelow et al., 1973) have been used as reinforcers for decreased drinking.Other investigators (Sulzer, 1965; Miller, 1972: Hunt and Azrin, 1973) have successfully applied similar contingency management techniques to alcoholics in the natural environment. However, failure to control for the influence of extraneous therapeutic variables (e.g., attention-placebo factors, job counseling) together with reliance on self-report measures of drinking behavior seriously limit the conclusiveness of these results. Objective assessment is particularly essential with operant techniques since consequent events must be systematically scheduled upon the occurrence or non-occurrence of drinking. Documentation of drinking in the natural environment is a difficult task since the alcoholic frequently consumes alcohol when he is alone. In lieu of direct observation, blood alcohol concentrations are an obvious means of objective assessment. Such data are most conveniently obtained via breath tests similar to the ones that law enforcement officers utilize to identify intoxicated motorists.The purpose of the present study was to investigate the influence of reinforcement contingencies on lowering blood alcohol concentrations obtained in an alcoholic's natural environment.     

Event-related potentials in neuropsychological studies of language

Experiments are described in which event-related potentials (ERPs) are employed to study the specialization of functions between and within the cerebral hemispheres during the performance of language and nonlanguage tasks by normal adults. Similar studies of deaf subjects suggest that the functional organization of the brain may be altered after different early language and sensory experiences. Studies of patients with alexia without agraphia suggest that the ERP may be a valuable tool with which to study cerebral reorganization after brain damage.     

The multiple roles of Broca's discovery in the development of the modern neurosciences

Using the classical clinico-anatomical correlation method of the French clinical school, Paul Broca confirmed the localization of "language" in the frontal lobe. He actually discovered the lateralization of language in the left hemisphere. These contributions eventually led to the demise of the older concept of the "sensorium commune," because Broca's ideas implied the presence of motor functions in the hemispheres. Although Broca worked within the theoretical motif of the "faculty" psychology, the reflex-oriented "associationist" psychology soon became the predominant theoretical framework of localization, because it accommodated the motor aspect of hemispheric function. Since Broca's time, the study of the biology of language has proceeded along two parallel but sometimes separate lines in the experimental and clinical traditions.     

Organization of short-term verbal memory in language areas of human cortex: Evidence from electrical stimulation

Short-term verbal memory (STVM) performance was measured during electrical stimulation of human left frontal-parietal-temporal cortex, at craniotomy under local anesthesia for the treatment of medically intractable epilepsy. The areas of cortex where stimulation alters language, as measured by object naming, are separate but adjacent to the areas where stimulation alters STVM. There are differential effects of stimulation during input, storage, and output phases of STVM at different cortical sites. These suggest that cortex adjacent to the posterior language area is a site of storage of STVM, while cortex adjacent to anterior language area is involved in retrieval from STVM.
