Habituating effects of nonhydrational oral stimulation on ingestive behaviors

The role of oral stimulation in the control of ingestive behavior was investigated using an airlicking procedure. It was hypothesized that the oral experience of airlicking would inhibit subsequent ingestive activity (water intake), possibly via an habituation process as suggested by recent research (Swithers, 1996). Rats were implanted with gastric cannulas and trained to lick at a stream of air. Experimental conditions con-sisted of combinations of airlicking and intragastric hydration followed by oral intake of water. In support of the main hypothesis, airlicking did reduce subsequent ingestive activity. While the role of habituation was not tested directly, the results lend support to the proposal that oral stimulation does control ingestion, and this control could act through an habituation process.     

Inferences about others from their reports about themselves

Subjects in this study were asked to infer an attribute of a target person on the basis of his report about himself: Two informational determinants of such inferences were varied: (a) reliability of the report, i.e. the belief that the target person would correctly report events that had actually occurred and (b) diagnosticity of the actual events, i.e. the belief that the actual events are indicative of the attribute. Normative considerations require that the effect of diagnosticity be dependent on reliability so that as reliability increases, judgment should become less regressive, i.e. vary more as a function of events' diagnosticity. The results indicate that subjects employed a simple but inappropriate averaging rule in combining reliability and diagnosticity information. This rule, like many other simplifying judgmental heuristics, resulted in inferences that were more extreme than warranted by normative models. The inappropriate combination of reliability and diagnosticity information may thus contribute to observers' tendency to over-attribute personal characteristics to others.     

Facilitating parental participation in preparing the therapy component of the stutterer's individualized education program

An eight-step evaluation and therapy enrollment process for the school-age stutterer to facilitate parental involvement in the development of the therapy component of the stutterer's Individualized Education Program (IEP) is described. Various evaluation tools that may be used in the process are noted, as is a resulting parent-clinician note of agreement, which may serve as the stutterer's therapy component of the IEP.     

Aversive conditioning in the sociopath

Results of two experiments on differential conditioning of the skin conductance (SCR) in sociopaths and normal control subjects are described. In the first experiment it was found that an equal number of sociopaths and control subjects were aware of the conditioning contingency. However, only the normal subjects displayed reliable differential SCR conditioning. Sociopaths showed a dissociation between verbal learning and conditioning of a physiological change. The second experiment examined the differential conditioning of normal subjects and sociopaths in partial remission. The number of aware subjects in the two groups did not differ. Aware subjects in both groups showed differential SCR conditioning. Differential conditioning in sociopaths did not persist over trials as it did in control subjects. A deficiency in ACTH 4–10 as well as neurological dysfunctions were considered possible factors in the etiology of sociopathy. Further research on the relation of neuropeptides to the etiology and treatment of sociopathy is suggested.     

Interest Inventories and the Developmental Framework

Interest inventories are of greatest usefulness for educational and vocational planning when the counselor is satisfied that the student is “ready” to indicate his interests. Since interests develop over time as the adolescent broadens his experiences, counselors are cautioned that more individual counseling is often necessary before interest inventories can be used as the basis of career decision-making. Viewed from this developmental point of view, interest inventories are examined as they are affected by the subject's age, social class, ego-strength, shift in major field, and ability. Judicious counseling could provide experiences to assist in raising career goals.     

College Adjustment and Performance of Low-Income Freshman Males

To examine the effects of an impoverished background on the college adjustment and performance of low-income freshman males, 36 entering freshmen from the lower income groups at a state university and a junior college were matched on American College Test scores and college of attendance with 36 control freshman males. A battery of tests of the personal characteristics important to college adjustment and success and of the level of aspiration was given both groups at the beginning of the first semester in college and at the end of this semester. The low-income group showed personal characteristics similar to those which have appeared in studies of college dropouts. One semester of college accentuated these characteristics. Nonetheless, the low-income group had as good or better college performance as measured by grade-point average at the end of one semester and possessed levels of aspiration equal to those of the control group.     

Mimics: A symbolic conflict/cooperation simulation program,with embedded protocol recording and automatic psychometric assessment

This paper describes an interactive software environment designed as a social interaction simulator with embedded comprehensive recording and flexible assessment facilities. Using schematized visual sketches similar to cross-cultural facial universals (Ekman, 1999), Mimics (Shmelyov & Aidman, 1997) employs a computer-game-like scenario that requires the subject to identify with anavatar and navigate it through a playing field inhabited byhosts who display a range of facial expressions. From these expressions (which are highly consequential), the player has to anticipate the hosts’ reactions to the avatar (which may vary from friendly to obstructing or aggressive) and choose between negotiating with a host (by altering the avatar’s facial expression), attacking it, or searching for an escape route. Comprehensive recording of player moves and interactions has enabled computation of several finegrained indices of interactive behavior, such as aggressive response styles, efficiency, and motivation in conflict/cooperation contexts. Initial validation data and potential applications of the method in the assessment of personality and social behavior are discussed.     

Intuition: A fundamental bridging construct in the behavioural sciences

The concept of intuition has, until recently, received scant scholarly attention within and beyond the psychological sciences, despite its potential to unify a number of lines of inquiry. Presently, the literature on intuition is conceptually underdeveloped and dispersed across a range of domains of application, from education, to management, to health. In this article, we clarify and distinguish intuition from related constructs, such as insight, and review a number of theoretical models that attempt to unify cognition and affect. Intuition's place within a broader conceptual framework that distinguishes between two fundamental types of human information processing is explored. We examine recent evidence from the field of social cognitive neuroscience that identifies the potential neural correlates of these separate systems and conclude by identifying a number of theoretical and methodological challenges associated with the valid and reliable assessment of intuition as a basis for future research in this burgeoning field of inquiry.
