Boredom: Practical consequences and a theory

Boredom is defined as a unique psychophysiological state possessing interrelated and inseparable emotional, motivational, perceptual and cognitive concomitants. Practical consequences of boredom are reviewed, including diminished performance efficiency, general life satisfaction and health. Finally, the outline of a theoretical model is presented.     

Odor production and utilization under conditions of nonreward and small reward

A series of five experiments was conducted to examine odor production and utilization under conditions of contrasting large and small reward. Using daily, eight-trial double-alternation sequences of reward (L)-nonreward (N) or small reward (S), i.e., LLNNLLNN and LLSSLLSS, appropriate patterning was shown only when an empty goalbox was initially encountered on N or S trials (Experiments 1–5). Manipulations designed to increase frustration, for example, preceding double-alternation training with a block of large-reward trials in Experiment 2, or increasing the L vs S ratio in Experiment 3, failed to yield patterning when small reward was presented at the start of the S-trial confinement period. Patterning was shown when small reward was presented at the end of the S-trial confinement (Experiments 4 and 5). Immediate vs delayed (30 sec) S or N trial goalbox removal failed to result in differences in patterning (Experiments 1 and 2). To distinguish odor production from odor use, subjects trained on an LLSSLLSS pattern preceded subjects trained on an LLNNLLNN pattern (Experiment 5). Because patterning failed to develop in the LLSSLLSS subjects and the first subject in the LLNNLLNN group, it was concluded that a discriminably different cue was not produced on S trials under the LLSSLLSS sequence when small reward was delivered at the beginning of the goalbox confinement period. Shifting small-reward delivery to the end of goalbox confinement resulted in the immediate display of patterning by the first LLNNLLNN subject, and the subsequent development of patterning by the LLSSLLSS subjects.     

Internal-External Control and beliefs about automobile travel

It was hypothesized that the Internal-External Locus of Control dimension (Rotter, 1966) would predict reported feelings about automobile travel and attribution of responsibility for automobile accidents. Relative to Externals, Internals were found (a) to attribute responsibility for automobile accidents more to internal, controllable causes; (b) to report less anxiety when travelling via automobile; (c) to report wearing seatbelts more often; and (d) to experience automobile travel as more interesting and involving.     

Relationship of vocational maturity to work values

This study examined the relationship of vocational maturity to work values. Two hypotheses were tested: (1) Vocational maturity is positively related to differentiation of work values within subjects. (2) Vocational maturity is positively associated with intrinsic work values and negatively associated with extrinsic work values. Sixty-two subjects enrolled in remedial reading at a community college were administered the Vocational Development Inventory-Attitude Scale and the Work Values Inventory. Data analyses supported hypothesis 1 for females, but not for males, and partially supported hypothesis 2.     

Some characteristics of concurrent discrimination and retention by monkeys

Before and after learning-set training, 12 rhesus monkeys were tested on the acquisition and retention of tasks consisting of eight concurrent object discrimination problems. Training on the concurrent discrimination was administered unitil a fairly stringent acquisition criterion was met. Under these procedures, retention, unlike acquisition, was little influenced by initial object preferences. Excellent retention was observed both before and after learning-set training. In a second experiment, these same monkeys were tested on a series of concurrent tasks which provided different numbers of objects as the sets of correct and incorrect discriminanda. Task solutions depended largely upon acquiring and retaining a list of correct objects despite designation of the large or small sets as the correct one. The animals seemed not to use “exclusion” strategies even when this might have provided an efficient task solution. It was considered that the monkeys' performances were based on stimulus sampling characteristics like those seen in other discrimination testing situations.     

Syntactic presupposition in sentence comprehension

Two experiments investigated the role of syntactic presupposition in sentence comprehension. In Experiment I subjects verified cleft, pseudocleft and factive complement sentences with respect to preceding context paragraphs, which contradicted either the assertion or the presupposition of the target sentence. Subjects took significantly longer to verify sentences with false presuppositions than sentences with false assertions. In Experiment II subjects verified cleft and pseudocleft sentences with respect to subsequently presented pictures. Once again, verification times for sentences with false presuppositions were significantly longer than verification times for sentences with false assertions. It was argued that these findings are more adequately explained by a “structural” hypothesis, than in terms of strategies designed to locate given and new information.
