Active and passive observers' attraction to a self-disclosing other

Active observer (participant) subjects were induced to make either a high or a low intimacy disclosure about themselves to a partner. Their (videotaped confederate) partner then disclosed either intimately or non-intimately in return. The impressions and attributions of these subjects were compared to the predictions of passive observer subjects (non-participants) who were each furnished with the original instructions, heard a tape recording of a different active observer's disclosure, and watched the same videotape of the confederate that person had seen. As expected, both active observers' responses and passive observers' predictions indicated a preference for the intimate partner. In addition, passive observers' attraction predictions were less positive than active observers' reports. But contrary to the hypotheses, passive observers predicted that active observers would attribute the partner's disclosure more to personalistic causes than was actually the case, and guessed inaccurately that active observers would interpret the partner's intimacy as an indicator of attraction. The methodological implications of these active-passive observer differences for research in self-disclosure and relationships are discussed.     

Encoding specificity and modality effects in episodic memory

Summary A modified Brown-Peterson paradigm was employed to determine the extent to which proactive interference effects of a sensory nature would influence the occurrence of sensory encoding specificity effects in episodic memory. Subjects presented with an auditory or a visual study list of five to-be-remembered (TBR) words engaged in either an auditory or a visual arithmetic distractor task for 30 s, and then received the first word in the study list as an auditory or visual intralist retrieval cue or received no cue. Presentation of the intralist retrieval cue in the modality of the study list enhanced the effectiveness of the retrieval cue, whereas presentation of the retrieval cue in the modality of the distractor task decreased the effectiveness of the retrieval cue. Sensory encoding specificity effects were largest when the distractor task occurred in the modality opposite to the modality in which both the study list and the retrieval cue were presented.     

Interviewee perceptions of an organisational careers guidance scheme

A study was carried out during the early stages of the introduction of a career development scheme in a large government department. Information relating to aspects of various careers counselling issues was gathered from staff who had received such counselling and from personnel staff responsible for its provision. The study shows, amongst other things, that the interviewers were perceived to use some counselling skills, that the interviewers claimed they experienced few problems of role conflict, but that the staff tended to identify the interviewers with management. The findings are discussed relation to the appropriateness of interviewing style and to the broader context of how individuals might influence their career development within the opportunities provided by the organisation.     

Experimental assessment of tinnitus aurium

A 32-year-old male volunteer with an eight year history of chronic unilateral tinnitus (ear-ringing) participated in a behavioral assessment strategy that included a series of measurement and modification procedures. A psychophysical matching technique was employed throughout a planned combination of procedures to assess and manipulate the intensity or loudness of tinnitus responses. Following baseline assessment, measurements were conducted at varying times of the day, concomitant with exposure to music, during progressive relaxation training, and under conditions of caffeine consumption. The value of careful assessment to describe cues and conditions associated with tinnitus and its reduction are discussed with implications for behavior treatment design and evaluation.     

BAND AID: First steps toward an ICAI system

BANDAID is an intelligent computer-assisted instruction (ICAI) system designed for students learning to program in BASIC. The major thesis is that beginning students need a friendly environment, that is, one in which information about the language and the system are immediately available. The system accepts most commands without switching levels: BASIC lines are parsed on input with very specific error messages. An editor allows corrections of BASIC lines. The program can be traced while running, and an indefinite number of HELP comments can be written for the system. Without leaving the BASIC environment, the user can interact with the CMS monitor of the main machine running the program. Although no English language comments or questions are allowed, the system is modular so that additions of restrictive dialogue interaction and guided tutoring are possible. Illustrations are presented showing the capabilities of the system. The paper also presents some of the implementation details of BANDAID. A flexible system requires implementation in LISP, so examples of how the system programmer interacts with LISP during debugging are given. Although still incomplete, the system runs satisfactorily and can be used easily by beginning students and by psychologists interested in how people learn complex subjects.     

A two-stage detection model applied to skilled visual search by radiologists

Harvard Medical School and Peter Bent Brigham Hospital, Boston, Massachusetts 02115 The model treats the detection of targets in a visual search task as a concatenation of two serial detection stages. Preattentive visual mechanisms in the initial stage function as a filter, selecting specific features of a visual pattern for the observer’s explicit attention and final cognitive evaluation. The model uses bivariate normal distributions to represent the decision variables for the two serial stages, assuming different parameters for the target and nontarget features in a test set. The model is applied to the detection performance of radiologists interpreting chest x-rays under various conditions of search. It accounts for the substantial improvement in radiologists’ ability to distinguish between target and nontarget test features when they had to search the x-ray images, compared to their performance without visual search. A change in the ROC curve between two different search tasks could be interpreted as a shift in the selection cutoff used by the preattentive filter.     

Picture perception: An analysis of visual compensation

Although geometric information is altered when a picture’s viewing point is changed, such changes often do not affect perception. Two experiments assessed pictorial perception relative to the distortions introduced by viewing point dislocation. Results provide a psychophysical demonstration of pictorial compensation and suggest that it is based on the discrepancy between the actual and an assumed-correct viewing position. An explanation of pictorial compensation is offered that could be applied to direct picture perception and to picture-in-a-picture perception.
