Information search and choice accuracy as a function of task complexity and task structure

Previous research has consistently shown that subjects switch to noncompensatory information search behaviour when task complexity increases. However, a rather specific class of tasks was used in these studies for which complete information search is not necessary to attain accurate task performance. In the present study information search behaviour, choice accuracy, subjective difficulty and confidence were registered under various task complexity conditions in two different task environments. In the first task, subjects had to make a choice between apartments; in the second task, a choice was required between baskets containing groceries of different prices. Forty subjects made choices by means of computerized information boards. The results showed effects of both complexity and type of task on information search behaviour. The lowest proportion of requested information and the most variable search pattern was observed for the apartments task in the complex task condition. However, accuracy remained constant over all complexity conditions. Together, the results suggest that under high task complexity levels subjects try to work smarter rather than harder. In the context of a choice requirement the specific task structure may allow them to switch to noncompensatory strategies while maintaining accuracy and avoiding the integration of large amounts of information.     

Anxiety responses to a divergent production task among high and low divergent performers

Undergraduate psychology students (4 men, 17 women) completed the Spielberger State-Trait Anxiety Inventory, wrote down as many uses as they could think of for each of a list of 30 items, and completed the anxiety inventory again. Divergent performance was defined as the total number of uses a subject listed. The hypothesis that divergent performance would be correlated with a reduction in state anxiety was confirmed.     

Task self-efficacy and task interest as a function of performance on a gender-neutral task

This study experimentally investigates several hypotheses about the relationships between performance on a gender-neutral task and gender, self-efficacy, performance attributions, and task interest. Ninety-two subjects were randomly assigned to a success or failure condition and attempted to solve a series of easy or difficult anagrams. Results indicated that changes in self-efficacy expectations as a result of task success or failure were in accordance with predictions from self-efficacy theory; 2 × 2 × 4 ANCOVAs, with the pretest as the covariate, were conducted on self-efficacy strength, level, and task interest. Subjects decreased their ratings of self-efficacy and task interest as a result of the failure experience, and the same ratings increased as a result of the success experience. Few gender differences were found, supporting the hypothesis that the sex linkage of the task significantly influences gender differences in self-efficacy. Analyses of global verbal and mathematical ability ratings resulted in the same trends. Finally, women in the success condition were significantly more likely than men in that condition to attribute their performance to luck; women in the failure condition were significantly more likely than men or women in any other group to attribute their failure to their lack of ability. Implications of these results for future research on career self-efficacy were discussed.     

Convergent and divergent thinking in verbal analogy

Individual differences in convergent and divergent thinking may uniquely explain variation in analogical reasoning ability. Across two studies we investigated the relative influences of divergent and convergent thinking as predictors of verbal analogy performance. Performance on both convergent thinking (i.e., Remote Associates Test) and divergent thinking (i.e., Alternative Uses Task) uniquely predicted performance on both analogy selection (Studies 1 and 2) and analogical generation tasks (Study 2). Moreover, convergent and divergent thinking were predictive above and beyond creative behaviours in Study 1 and a composite measure of crystallised intelligence in Study 2. Verbal analogies in Study 2 also varied in semantic distance, with results demonstrating divergent thinking as a stronger predictor of analogy generation for semantically far than for semantically near analogies. Results thus further illuminate the link between analogical reasoning and creative cognition by demonstrating convergent and divergent thinking as predictors of verbal analogy.     

Primary process thinking, divergent thinking, and coping in children

The relationships among primary process thinking, divergent thinking, and coping were investigated in fifth-grade children. Specifically, it was hypothesized from psychodynamic theory that access to and integration of primary process thinking would be positively related to divergent thinking and that both integration of primary process and divergent thinking would be predictive of coping ability. The Rorschach (Holt's scoring system) and Alternate Uses Test (spontaneous flexibility score) were administered to 53 fifth-grade children. Zeitlin's Coping Inventory, a teacher's rating scale, was the coping measure. Results confirmed the hypotheses for boys in that the percentage of primary process and the Adaptive Regression score on the Rorschach were significantly related to divergent thinking, r(27) = .33, p less than .05 and r(27) = .34, p less than .05, respectively. Divergent thinking was significantly related to teachers' ratings of coping ability for boys, r(27) = .58, p less than .01. There were no significant relationships among the variables for girls. These sex differences in the pattern of correlations are consistent with previous findings.     

Cue enhancement as a function of task set

The hypothesis was tested that the intention to use a particular cue relation would enhance the effectiveness of that particular cue in determining the resulting perception. For this purpose, a situation was presented in which the apparent depth position of an object in a configuration of objects would differ depending upon which of two possible cue relations (size cues) were used. The results support the conclusion that the perceived depth position of the object differed in the expected directions as a function of the task set. The data of the study are discussed with respect to the “adjacency principle” which states that cue efficiency is determined by the relative adjacency of objects between which the cues occur. Although the effect of cue set upon the perception seems to be small compared with that of adjacency, it cannot completely be ignored.     

Conformity as a function of task generalization and relative competence

Subject correctness and group agreement were varied for college subjects engaged in a light discrimination task. On another task, employing multiple-choice questions about Canada, the dependent variable of conformity was assessed to examine generalization of relative competence formed on the light discrimination task. It was seen that (1) relative competence was seen to mediate conformity for a specific task (Canadian Knowledge Inventory), but did not generalize across tasks (i.e. from the light discrimination task to the Canadian Knowledge Inventory); (2) with respect to the Canadian Knowledge Inventory, subjects who perceived themselves as more competent than the group did not conform as much as those who either perceived themselves as less competent than or as competent as the group; (3) the experimental manipulations did not affect conformity, further supporting the findings that perceived competence does not generalize across classes of tasks; (4) females conformed more than males: and (5) nonsuspicious subjects conformed more than suspicious subjects.     

Emergent leadership as a function of sex and task type

Emergent leadership was examined in relation to sex and task type; 120 subjects participated in four-person mixed-sex groups. Three task conditions (masculine, neutral, and feminine gender orientations) were tested with 10 groups in each condition. It was predicted and found that more men than women would emerge as leaders in the masculine and neutral task conditions, while more women would assume the leadership role in the feminine task condition. The effects of the gender orientation of a task are discussed. It is suggested that expertise with a task may explain the task type effect found.This study is based on the senior author's master's thesis, conducted at Wayne State University under the direction of the second author.     

Recall as a function of orienting task and retrieval cue

Abstract.— In an incidental learning experiment, a 40 word list with 4 words representing each of 10 taxonom-ic categories and beginning with each of 10 first letters was presented to 120 subjects. Half the subjects sorted the words according to category, half according to initial letter. After an interval of either 1 or 6 min, retention was measured with cued or free recall tests. The subjects in the Category sort-Category cue condition obtained higher recall than the subjects in the Category sort-Letter cue condition, whereas level of recall did not differ between the Letter sort-Letter cue and Letter sort-Category cue conditions. These results together with other results from the experiment were considered as arguments against the Encoding Specificity Principle but in favor of a theory separating encoding from retrieval.     

Uric acid and divergent thinking: a possible relationship.

An exploratory investigation of the relationship between serum uric acid levels in male university students and their scores on tests of convergent and divergent thinking was carried out. The data suggested that uric acid levels are lower in highly divergent thinkers than in less divergent. This led to the speculation that uric acid may be an important biochemical precursor of intellectual functioning. If it does affect intellectual functioning, this may result from the action of uric acid as an endogenous cortical stimulant, or possibly from its action as a facilitator of learning.     

Incidental learning as a function of anticipated task difficulty

Three experiments were conducted to demonstrate the effects of motivational arousal, due to anticipated task difficulty, on retention of familiar and unfamiliar incidental materials. Brehm, Wright, Solomon, Silka, and Greenberg (1983) have provided evidence that motivational arousal in immediate anticipation of a task is a nonmonotonic function of task difficulty, with difficult tasks producing a relatively higher level of motivational arousal than easy or impossible tasks. It was predicted that increased motivational arousal would facilitate retention of incidentally presented familiar materials (presumably more easily retained) and interfere with retention of incidentally presented unfamiliar materials (presumably less easily retained). In Study 1, subjects anticipating either an easy or a difficult task were exposed to familiar and unfamiliar first names. The predicted interaction between task difficulty and familiarity on recall of the first names was reliably supported. In Study 2, an impossible task condition was added. The results indicated that an effective impossible condition had not been created. In a third study designed as a procedural modification of Study 2, the predicted nonmonotonic interaction was found. Theoretical implications are discussed.These experiments were ably conducted by Ralph Young, whose help is gratefuly acknowledged. We would like to express our gratitude to Jack Brehm for invaluable suggestions concerning this research.     

Proactive inhibition as a function of orienting task characteristics

Two release from proactive inhibition experiments were conducted, in which orienting tasks were employed to direct subjects' attention to particular features of words. Experiment 1 employed two such tasks which emphasized either semantic or nonsemantic features, while both orienting tasks in Experiment 2 directed attention to semantic features of words. Although significant release was obtained with a change in task in these experiments, the level was considerably lower in Experiment 2 than in Experiment 1. The data were interpreted in terms of a theoretical orientation that emphasizes item differentiation as a major determinant of retrieval probability. It was argued that the degree of differentiation depends to some extent on the specific tasks employed and the extent to which they direct attention to different word features.
