Ambiguity,cubist works of art,and preference

Number of one sec views and verbal judgements of interestingness and pleasingness of Cubist paintings were found to be a function of subjective ambiguity, defined in terms of the Shannon-Wiener average information measure, especially when an expectancy had been established regarding the identity of the main object or person in the paintings. Viewing behaviour was found to increase with subjective ambiguity; verbal judgements were found to decrease. Titles corresponding to varying degrees to the content of the paintings or instructions involving guessing were used to manipulate expectancy. An attempt was made to explain these findings and those involving recall of titles by making reference to Berlyne's point of view and the experimental literature.     

Multiple meanings,number of related meanings,frequency of occurrence,and the lexicon

A series of experiments was conducted examining lexical access of words with multiple meanings. Words with many meanings were accessed faster than words with few meanings. This effect was obtained independently of word frequency. Furthermore, while words may have several etymological derivations, the number of derivations does not affect access. Finally, among words with an equal number of derivations and an equal number of meanings, those whose meanings tend to be associated with only one derivation are also accessed faster. The relation between number of meanings and word frequency is discussed, especially with respect to the role number of meanings may have played in other research.     

The effect of anxiety,reinforcement, and intelligence on the learning of a difficult task

The effects of anxiety, reinforcement, and intelligence were studied on the learning of a difficult task (paired associates with 1% association values) in 252 subjects studying in class IX in Chandigarh schools (mean age, 14.7 years). A 2 × 3 × 3 factorial design was used with two anxiety groups (high and low), three reinforcement conditions (praise, reproof, and praise + reproof), and three levels of intelligence (high, middle, and low). In general, the results were in line with the Sarasonian theoretical framework that anxiety shows its debilitating effects under certain conditions, but not all. At upper levels of intelligence, neither anxiety nor reinforcement was found significant. At lower levels of intelligence, anxiety was found to interfere with learning under all the reinforcement conditions. It was found further that the most affected group was the middle intelligencehigh anxiety group. This group performed better under praise than under praise + reproof and reproof alone.     

Verbs,time, and modality

In the first part of this paper it is argued that Vendler's classification of verbs into aspectual categories, called activities, accomplishments, achievements, and states, is better seen as classifying the meanings of sentences, and a recursive scheme for describing the aspectual character of sentences is presented. In the second part, this scheme is applied to the discussion of the epistemic and deontic meanings of the modal verbs must, will, and may. In particular, the relation between the “future” and “nonfuture” senses of epistemic will is examined.     

Locus of control,historical context,and black physical self-perception

Effects of locus of control on physical self-perception of black men were examined in 1968 and 1975. Externally oriented subjects were hypothesized to perceive themselves to be more Negro in appearance than they were judged to be by observers. The hypothesis was tested by comparing the subjects' own appearance judgments with the mean judgment of three observers on a scale of 15 faces which changed incrementally from Negro to Caucasian. The hypothesis was contradicted in the 1968 study and supported in the 1975 study. These discrepant results were interpreted in terms in historical events at the time of data collection.     

Father identification,achievement, and occupational behavior of rural youth

Comparisons were made between the post high school plans and the adequacy of father identification of male adolescents from rural economically deprived areas. The subjects were divided into two groups, low identification males (LIM) and high identification males (HIM) based on independent evaluators' judgments of the adequacy of their fathers. Each group's responses to a questionnaire concerning future plans and aspirations were compared. In general, the hypotheses predicting that HIM subjects have higher levels of aspiration, more self-confidence and greater satisfaction with school experiences were confirmed by the data.     

Effects of long- and variable-duration signals for food on activity,instrumental responding,and eating

Incentive-motivation theories typically assume that the conditioning of appetitive motivation involves the same parameters as Pavlovian salivary conditioning. In contrast, the Soltysik-Konorski model asserts that drive is inhibited by stimuli closely associated with food (salivary CSs) and augmented by stimuli more loosely associated with food (long and variable CS-US interval). Experiment 1 examined this latter proposition. Sixty-four rats were given extensive exposure to each of four environmental CSs, two while hungry and two while satiated. Within each deprivation condition, food was given 30–300 sec after placement of the rats in one environment, and was not given in the other environment. Performance on three separate measures—activity, lever-pressing, and food consumption—was higher in the environments previously associated with food. Experiment 2 examined the effects of discrete stimuli presented in advance of eating; in accord with the results of Experiment 1, food consumption was greater after a stimulus (1- to 9-min duration) previously paired with food than after no stimulus or after a stimulus unpaired with food. The overall results indicate (a) that stimuli associated with food become capable of facilitating a variety of food-directed behaviors, possibly via the conditioning of a common appetitive system, and (b) that a close association between the stimuli and food is not essential for such conditing to occur.     

Crowding,contagion, and laughter

The phenomenon of contagion is analysed in terms of the intensification explanation of the effect of crowding (high density) on humans. According to the analysis, high density should be expected to increase contagion of a model's behavior. Groups of three subjects and a confederate listen to humorous tapes under low or high density conditions. In half of the groups the confederate smiles and laughs a good deal during the tapes; in the other half, she does not laugh and smiles only a few times. The subjects are filmed and their reactions to the tapes are rated. As predicted, high density combined with a laughing model results in more laughter by the subjects, while the other three conditions do not differ appreciably. The lack of effect of high density when the model does not laugh is seen as supporting the intensification explanation of crowding as opposed to an arousal explanation.     

Calibration of probability assessments by professional blackjack dealers, statistical experts, and lay people

The question addressed in this study is whether experts are better calibrated than lay people. We investigated how well people are calibrated when they assess the probabilities of card combinations in the game of blackjack. Three groups of subjects were used: professional dealers, statistical experts, and control subjects. The results showed that experience and statistical expertise do not make people better calibrated in this task. It is argued that the concept of calibration is not wholly appropriate to describe the obtained deviations from the normatively correct responses. This is illustrated by a discriminant analysis performed on the signed deviation scores, which resulted in an almost perfect separation of the three groups, although they were overlapping with respect to calibration.     

Leisure,materialism, well-being and the environment

Introduction

There are increasing concerns that people in modern societies spend too much of their leisure time on activities such as shopping and watching television and that this undermines human well-being and damages the environment.

Congruency,consistency, and differentiation as predictors of job satisfaction within the nursing occupation

Holland's (Making vocational choices: A theory of careers, Englewood Cliffs, N.J.: Prentice-Hall, 1973) congruency, consistency, and differentiation terms were used as independent variables to predict job satisfaction (JS) within the scope of a single occupation, rather than on the comparison between occupations. Based on the responses of 126 registered nurses on the specially designed List of Courses in Nursing (LCN) Inventory the congruence hypothesis was confirmed, while the consistency and differentiation hypotheses were only partially supported. The hypothesis on the additive relationship among congruence, consistency, and differentiation with JS was confirmed. The theoretical and practical implications are discussed.     

Semantic field,naming, and auditory comprehension in aphasia

The status of semantic fields for 16 target nouns was compared in high and low comprehension aphasics, brain damaged, and normal controls, by measuring latency and miss rate for recognition of six classes of associates, which were presented orally on tape. The ability to name each target was also examined as a function of the integrity of the subject's semantic field for that word. Low comprehension aphasics showed both quantitative and qualitative changes in semantic fields, while milder aphasics showed only mild quantitative impairment, as compared to controls. Both latency and miss rate measures indicated that failure to name a word is associated with reduced semantic field for that word. This result is interpreted as supporting the view that nameing is, in part, determined by the convergence of associations.     

Faith,Fact, and Behaviorism

David Hume argued that ought cannot be derived from is. That is, no set of facts, no amount of scientific knowledge, is by itself sufficient to urge us to action. Yet generations of well-meaning scientists (more and more as secular influences grow in the West) seem to have forgotten Hume''s words of wisdom. All motivated action depends ultimately on beliefs that cannot be proved by the methods of science, that is, on faith.     

Escape conditioning and goal punishment: Effects of acquisition trials,initial punishment trials,and CS extent

In the first of three experiments in which albino rats were given spaced shockescape trials in a straight runway, groups of 6 animals were given 6 or 24 trials followed by extinction, with or without goal-box punishment. Punishment facilitated behavior after 24 trials but did not significantly affect it after 6. Both punishment and 24 trials led to more “abrupt” extinction. In the second experiment, 6 groups of 6 animals received 6, 12, or 24 trials followed by 54 extinction trials with or without goal punishment on the first 18. All punished groups ran self-punitively, and acquisition trials effects were apparent during and after punishment. In the third experiment, buzzer extent, or duration, was manipulated, and longer extents produced stronger self-punitive effects. The results of all three experiments were interpreted in the context of presumed directive effects of aversive and conditioned aversive stimuli.     

Values,preferences, needs,work ethics,and orientations to work: Toward a conceptual and empirical integration

There have been comparatively few attempts on either the conceptual or empirical level to integrate values, preferences, needs, work ethics, and orientations to work. A rationale outlining the way these concepts can be related to each other, is presented. It is maintained that these concepts are categories of relations between humans and work. These categories are qualitatively similar and differ principally in the level of generality of the characteristics of work considered. Complete-link cluster analysis is suggested as a method of analysis compatible with the proffered rationale. Two studies are presented with data gathered during the development of two versions of Work Aspect Preference Scale (WAPS). The samples for the two studies both comprised senior high school students, controlled for sex and age, who were administered the WAPS. Study 1 had a sample of 532 while Study 2 had a sample size of 482. Both sets of data were cluster analyzed. Results indicated a very substantial amount of agreement between the two samples, particularly at the more general levels of clustering. The bipartite and tripartite groupings of vocational needs suggested by L. H. Lofquist and R. V. Dawis (Journal of Vocational Behavior, 1978, 12, 12–19) were confirmed as were the findings of J. Mortimer (Sociology of Work and Occupations, 1975, 2, 29–53). Other clusters were also identified with findings from previous research. It is concluded that the investigation of preferences at different levels of generality and the interrelation between these levels shows great promise for both the researcher and the counselor and therefore merits more research effort.     

Cognitive flexibility-rigidity, repetition effects, and memory

This experiment examined the role of cognitive flexibility-rigidity in memory. On the basis of several personality tests, subjects were classified as flexible, intermediate, or rigid, using a postexperimental blocking procedure. All subjects were given a perceptual grouping task, which masks the meaningful structure of the material. Subjects have the option of discovering the more meaningful structure consisting of word pairs, or alternatively, processing less meaningful chunks of letters. Results were that flexible subjects recalled substantially more items than intermediate and rigid subjects, in that order. In addition, subjects given different (varied) groupings of the letter chunks recalled substantially more than subjects given repeated presentations of the same grouping structure. Transfer tests indicated that subjects acquired different coding strategies under varied and constant input. Repetitious input led subjects to adopt inefficient strategies in processing the material to be remembered, whereas varied input led subjects to adopt efficient encoding strategies.     

Symmetry,scale types,and generalizations of classical physical measurement

A review is presented of a number of recent results concerning fundamental measurement structures with a particular emphasis on generalizations of physical measurement. Relational structures are classified in terms of richness and redundancy of their automorphism groups (i.e., in terms of their symmetries). By means of this classification, the possible types of measurement scales are described, and the possibilities for structures with concatenation operations (either associative or nonassociative and either positive or intensive) and for conjoint structures whose automorphisms factor into component automorphisms are explicitly spelled out. Certain conjoint structures with concatenation operations on components are viewed as generalizations of classical physical measurement and some of their most important algebraic and representational properties are explored.     

Commitment,ego-involvement,and resistance to attack

Subjects with initially extreme or moderate positions (based on a median split) recorded a consonant speech under public, private, or no commitment and later received a strong, mild, or no attack on their position. Extremes were more ego-involved in terms of wider latitudes of rejection, narrower latitudes of non-commitment, and greater resistance to attack, relative to moderates. Commitment had no effect for extremes, suggesting a ceiling effect on changes in the latitudes and resistance to attack for initially high levels of ego-involvement. For moderates, commitment resulted in narrower latitudes of noncommitment, wider latitudes of rejection (greater rejection of discrepant positions), and greater resistance to attack, suggesting that commitment may elevate ego-involvement with the issue. Commitment and ego-involvement may increase the salience of one's attitude position in later situations, thereby increasing the probability of attitudeconsistent behavior.     

Psychosis,symbol, affectivity 2: another perspective on the treatment of psychotic disorder

This is the second of two papers concerning our study into an integrated approach to psychotic disorders conducted at the University Psychiatry Unit of Palermo’s Polyclinic over approximately 15 years; this paper concentrates on the clinical phenomena. The study aimed to find the best possible treatment and to improve the prognosis of this patient group. We have explored the efficacy of a range of psycho-therapeutic (cognitive-behavioural, systemic-relational, psychodynamic, group and others), psycho-pharmaceutical, psychiatric rehabilitative and psycho-educational treatments, with a hermeneutic approach instead of a systematic one. The study’s conclusions, described in the paper, are that all psychotic functions start with a nuclear psychic issue connected to emotional development. We describe how the most significant symptoms of acute psychotic manifestations (delusions and misperceptions) make use of an encrypted psychological meaning that can be decoded through the patient’s symbolic language. This language is a key element in diagnosis and in the choice of treatment. The paper describes how we revised our understanding of psychosis from being a brain disease to being a process aimed at the rearrangement of psychic functioning. Our significant results are described.
