Disinhibition of return: Unnecessary and unlikely

Recently, from data obtained with a temporal order judgment (TOJ) task, Gibson and Egeth (1994) concluded that inhibition of return (IOR; a response time effect that reveals slower responding to targets at previously cued versus uncued locations) reflects impaired perceptual processing. By replotting their data, we demonstrate that the perception of temporal order is influenced only by the facilitatory effect of a cue at short stimulus onset asynchronies (SOAs) and is unaffected by IOR at long SO As. The target paper proposed that, when extra stimuli are presented at task-relevant locations (i.e., in the TOJ task), IOR is prevented by a hypothetical process that is known as disinhibition of return (DOR). We argue that the assumptions that IOR affects perceptual processing and that DOR exists are unnecessary, as a more parsimonious response-based interpretation of IOR is consistent with their data. Further, we summarize recent results and present new data that demonstrate that DOR is unlikely.     

Interpersonal needs and functional area of management

This study examines a sample of first-semester MBA students to determine the relationship between their interpersonal needs and their preferences for a functional area of management. The students were categorized according to their preference for one of the following eight functional areas: accounting, systems analysis, finance, small business management, engineering, marketing, manufacturing management, and personnel management. Interpersonal needs were measured by the Fundamental Interpersonal Relations Orientation (FIRO-B) instrument developed by W. C. Schutz. Significant differences in interpersonal needs were found among students preferring different functional specialities. Implications of the results are discussed in terms of occupational choice processes.     

Nonverbal indicators of Affect and Deception in an Interview Setting1

A study was conducted to identify codes of nonverbal behavior which could be used by interviewers in a standard field interview to systematically assess deception and emotional states of respondents. Ten male and 10 female subjects were interviewed on topics that had been pretested to arouse in them pleasant involvement, passivity, and unpleasant involvement. Subjects were also instructed to lie to the interviewer on issues of importance to them. Eye contact was measured by observation through a one-way mirror. Smiles, gestures, self-manipulations and postural shifts were scored from videotapes of the interview. The most distinctive patterns of nonverbal cues occurred with unpleasant-involvement and deception questions. The former state was characterized by increases in smiling, self-manipulations, and postural shifts. Deception responses were marked by decreases in smiling and increases in self-manipulations and postural shifts. Results also suggested that eye contact functioned as an intensifier of affect.     

Sensitivity to sucrose in smokers and nonsmokers: A comparison of TSD and percent correct measures

Ten smokers and 10 nonsmokers were compared for taste sensitivity to sucrose on two discrimination tasks, one at near-threshold (NT) concentration level and one at suprathreshold (ST) concentration level. The data were analyzed using the d_s and area under ROC curve measures based on the theory of signal detection (TSD). and by using the percentage correct responses. Analysis of both TSD measures showed smokers to be significantly more sensitive than nonsmokers on the NT .task and more sensitive on the ST task, but not significantly so. Comparison of mean percent correct responses showed no significant differences. A reflexive enhancement phenomenon was suggested as a possible interpretation. A decreased sensitivity to the bitter taste in smokers apparently results in an increased sensitivity to the sweet taste.     

Behavioral techniques in the treatment of obesity: A comparative analysis

The relative efficacy of the major techniques typically used in behavioral treatment programs for weight reduction was investigated using obese adult volunteers. Study 1 compared the effects of self-monitoring, self-control procedures, monetary rewards, aversive imagery and relaxation training. These procedures resulted in significantly greater weight reduction than either a no treatment group or subjects who graphed and recorded daily weight. Self-monitoring of daily caloric intake was as effective as the other methods, both singly and combined, over a 4 week treatment period. Study 2 compared the long-term effects of self-monitoring vs the full complement of behavioral techniques used in Study 1. The full behavior management program was significantly more effective, both during the treatment period and at 3 and 12 week follow-ups, although self-monitoring again produced substantial weight loss.
