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.     

Semantic specificity in cued recall

In three cued recall experiments, extralist retrieval cues that were congruous in meaning to an encoded target pair of words produced better recall of the targets than wh6n the cuetarget relation was incongruous. However, this result, which differs from that of other experiments, depended in some cases on scoring recall of a target pair when either member of the pair was recalled. It is argued that (1) pairs of words are typically stored as higher order units, (2) the best test procedure is to request recall of both members of the pair when an extralist cue is presented, and (3) semantic features provide an important dimension in the mnemonic representation of word events.     

A challenge to vocational psychology: How important are aspirations in determining male career development?

Nationally representative longitudinal data on 1394 employed white men aged 15 to 24 in 1966 were used to assess whether job opportunities or vocational aspirations are the more important determinants of later job held. Support was found for two hypotheses: (a) men more often achieve congruence between their aspiration and their field of employment by changing aspirations to match the job rather than vice versa; and (b) aspirations for field of work generally are not as useful as actual job field for predicting the field of jobs held 1 to 5 years later. Contrary to expectation, middle-class young men were no more able to attain their aspirations either for field of employment or for status level of occupation than were lower-class male youths. These results suggest that although aspirations have some predictive power, the opportunity structure—which both conditions aspirations to narrow ranges early in life and affects the direction of early career development—is too often neglected by vocational psychology. One suggestion for counseling practice is that interest and maturity assessments be used as sources of information to both client and counselor about past influences. Attempts to actually counteract those influences should be clearly specified as such and separated from the assessment process.     

The dilution effect: Nondiagnostic information weakens the implications of diagnostic information

In a series of studies, subjects were asked to make predictions about target individuals. Some subjects were given information about the target which pretest subjects had judged to be “diagnostic”—that is, had judged to be usefully predictive of the outcome. Other subjects were given a mix of information judged to be diagnostic and information judged to be “nondiagnostic” by pretest subjects—that is, judged to be of little value for predicting the outcome. Subjects given mixed information made much less extreme predictions than did subjects given only diagnostic information. It was argued that this “dilution effect” occurs because people make predictions by making simple similarity judgments. That is, they compare the information they have about the target with their conception of outcome categories. The presence of individuating but nondiagnostic information about the target reduces the similarity between the target and those outcomes that are suggested by the diagnostic information. One of the major implications is that stereotypes and other “social knowledge structures” may be applied primarily to abstract, undifferentiated individuals and groups and may be largely set aside when judgments are made about concrete, individuated people.     

Selective information use and perseveration in the search behavior of infants and young children

Two experiments examined the early development of selective information use in search. The first experiment tested 9- and 16-month-olds on a modification of Piaget's Stage IV object permanence task. It examined infants' use of information from previous experiences with an object (prior information) and from the most recent hiding (current information) to locate a hidden object. In the second experiment, 2-, $\text{2}\text{1}\text{2}$-, and 4-year-old children received these same sources of information along with new forms of prior and current information: information about the typical locations of objects (location specificity) and verbal information. No systematic perseveration was observed at 9 months, although previous findings related to perseveration were replicated. Perseveration was found at 16 months, but there was also evidence of selectivity at that age. When errors occurred, they tended to be to the prior location, but they were infrequent in comparison to correct searches at the current location. The preschoolers, while continuing to show perseveration, were more consistently selective than the infants. They also showed considerable generality in extending their selectivity to new sources of information.     

Irrelevant thoughts,emotional mood states,and cognitive task performance

In two experiments, we investigated the relationship shared by irrelevant thoughts, emotional mood states, and cognitive task performance. At an empirical level, irrelevant thoughts were defined as thoughts that did not facilitate successful task performance. We used the same general procedure for both experiments: three groups of college students received happy-, neutral-(control), or sad-mood inductions and performed a memory task. The procedure for obtaining thoughts varied between experiments. The subjects in Experiment 1 listed their thoughts after the memory recall task. In Experiment 2, the subjects were tape-recorded while performing a memory task and producing concurrent verbal protocols. The subjects in both experiments then judged their thoughts in terms of frequency, intensity, and irrelevance. We found a similar pattern of results in both experiments: (1) The proportions of irrelevant thoughts and recall performance were negatively related, and (2) happy and sad students produced reliably greater proportions of irrelevant thoughts than did neutral (control) students.     

Organizational and family systems factors in stress among ministers

Forty-one Protestant ministers completed measures of stress-related symptoms, family of origin contact, church governing body density, history of pastor-parish conflict in the church, and a measure of Bowen's (1959b/1985) concept of emotional triangles. A denominational executive provided ratings of each church's history of pastor-parish conflict. Path analysis using multiple regression showed support for a model in which governing body density and history of conflict predicted emotional triangles, and emotional triangles predicted stress symptoms. Contact with the pastor's family of origin moderated the relationship between emotional triangles and stress symptoms. Results suggest that the organizational and family ecology of the ministerial role can be important in understanding occupational stress among ministers.     

The relationship of estimated comprehensibility to the rate of connected speech

The relationship between subjective estimates of the comprehensibility of connected, freerunning speech and rate of speech was investigated for each of two types of time-compressed speech: pitch-varying speeded speech and pitch-normalized compressed speech. The midpoints of the resulting functions approximated the values obtained by a previously described speechrate tracking method. For equivalent degrees of comprehensibility, rates were higher for compressed speech than for speeded speech, indicating that estimates are sensitive to the intelligibility of speech. Subjective estimates of comprehensibility of time-compressed speech provide a means of assessing the itelligibility of connected speech.     

Behavior analysis of cigarette smoking

Patterns of cigarette smoking, treated as series of discrete events in time, were investigated with a variety of quantitative techniques designed to characterize individual subject smoking series and to illuminate the relationship between cigarette smoking and environmental events. Data were collected from a total of 35 subjects who were either participants in residential laboratory studies or in a smoking cessation program. Cigarette smoking events were found to be fairly irregularly distributed with respect to time within individual subject series. However, strong dependencies were found between the occurrence in time of individual acts of cigarette smoking and coffee drinking. In addition, the distribution and frequency of smoking events throughout one-hour activity sequences were found to be dependent upon the nature of the activity, and the temporal scheduling of activities was found to affect several quantitative indices of smoking patterns.     

The general psychophysical differential equation: A comparison of three specifications

The general psychophysical differential equation, dy/dx = W₂(y)/W₁(x), with the solution y = f(x), where x and y are subjective variables and W₁ and W₂ their subjective Weber functions, is (a) compared with a corresponding functional equation, and (b) studied from a stochastic point of view by error calculus, Methods for evaluating and handling divergences are proposed and illustrated for a number of combinations of Weber functions. It is shown that either the differential: and the functional equations have the same solution or the difference between the solutions is negligible compared to empirical scatter. The error calculus gives the same result: either no error at all or a negligible one.
