Motivated remembering efforts during tip-of-the-tongue states

Hart (1965) argues that the feeling of knowing in tip-of-the-tongue (TOT) states monitors memory content and motivates retreival efforts. Although a number of studies have examined the memory-monitoring accuracy of feelings of knowing and not-knowing, no studies have focused directly on the hypothesized motivational function of these feeling states. This second function of memory feeling states is investigated in this study by assessing the degree to which TOT and Don't Know (DK) states interfere with a subject's ability to perform well on a concurrent task. Subjects studied a list of arbitrary word pairs for 3, 5, or 7 seconds and then provided Recall, TOT, or DK reports in an immediate recall test. Performance on the simple number-probe task that followed each memory report was poorer on TOT trials than on DK trials. This effect did not vary as a function of encoding time. Since covert memory searches were possible on both TOT and DK trials, it is concluded that the performance decrement observed on TOT trials is due to the fact that covert TOT target searches command processing capacity that might otherwise go to the concurrent number-probe task. The absence of an encoding time effect suggests that TOT states do not monitor the associative strength of target traces as Hart (1967) has proposed. The findings in this study are interpreted as providing support for the proposition that the feeling of knowing in the TOT state influences the setting of capacity-allocation priorities in the memory system.     

Life history and vocational interests

To obtain some information concerning the antecedents of various forms of vocational interests, scores on the 22 basic interest scales of the Strong Vocational Interest Blank (SVIB) were correlated with 389 life history or autobiographical data items. Items yielding significant correlations were clustered on the basis of item content. The clusters obtained for the business management, science, and adventure scales are presented and discussed. Subsequently, certain general conclusions are drawn concerning the life history correlates of inventoried vocational interests.     

Rule learning in children: Multiple-set training and intermediate-size transposition

Two experiments were conducted in which the subjects were trained to choose the middle-size stimulus in either a single stimulus set or in each of two nonoverlapping stimulus sets. Following criterion, each subject was presented with a series of 12 test trials involving a new stimulus set. In Experiment 1, kindergarten children tended to choose the middle-size test stimulus if the test set consisted of stimuli intermediate in size to the stimuli in the smaller and larger training sets. When the test stimuli were all larger than any of the training stimuli, the probability of choosing the middle-size stimulus increased as the distance between the two training sets increased. Three groups of children participated in Experiment 2: a kindergarten group, a first-grade group, and a first-grade group that experienced middle-size training a year earlier. The distance between training sets and two training procedures affected the three groups in a similar manner during acquisition, but several interactions were obtained during the test. The findings were discussed in terms of the Lane and Rabinowitz (D. M. Lane & F. M. Rabinowitz, Child Development, 1977, 48, 412–426) rule based theory of intermediate-size transposition and suggestions were made as to how children acquire the concept of middle.     

Measuring the importance of cues in judgment for individuals: Subjective theories of IQ as a function of heredity and environment

To measure the relative subjective importance attached to heredity and environment, undergraduates, graduate students, and faculty were asked to predict the IQ scores of hypothetical adopted children based on the IQs of the biological mother and father, the IQs of the adoptive parents, and the socioeconomic status of the adoptive parents. Intuitive predictions of IQ were inconsistent with additive, multiple regression models. Rather, the data for individual subjects were consistent with a configural-weight averaging model. Weights derived from this model were correlated with ratings of the relative importance of cues. Judges who rated the environment more important not only had greater weights for the environmental variables, but also placed greater weight on high rather than low scores. The judges who rated heredity more important than environment had greater estimated weights for heredity information and for lower-valued information. Results were thus consistent with the hypothesis that model-derived relative weights and individuals ratings of the relative importance of cues are both measures of the importance that individuals attach to these cues.     

Dimensional separability or flexibility of attention? Age trends in perceiving configural stimuli

The hypothesis that perceptual development proceeds from less to greater dimensional separability was tested by giving a speeded classification task to first and fouth graders. In Experiment 1, children sorted line drawings of a cartoon figure into two piles according to his eyes (open or closed) or his mouth (smiling or frowning). First graders exhibited the pattern characteristic of integral dimensions: An interference effect was found when dimensions were combined orthogonally and a facilitation effect when dimensions were correlated, relative to a condition in which only one dimension varied. Fourth graders exhibited an optional separable pattern: There was facilitation in the correlated condition but no interference in the orthogonal condition. These results support the hypothesis that development proceeds toward greater flexibility of attention rather than simply toward increasing separability. A flexible field hypothesis of visual attention was suggested to explain how older children can exercise such optional separability. This hypothesis correctly predicted the asymmetrical relation between dimensions found in Experiments 2 and 3: For both first and fourth graders, the eyes of a cartoon figure (open or closed) and his location (right or left) were nonseparable when the eyes were relevant and separable (or optional separable) when location was relevant.     

Self-focused attention and reactions to fear

Two studies were conducted to study the effect of self-focused attention on behavioral responses to fear. In Experiment 1, phobics and nonphobics were asked to approach and hold a snake either in the presence of a mirror or with no mirror. In Experiment 2, high and low private self-conscious subjects were asked to submit to a series of either mild or strong electric shock for humanitarian reasons. In each case, self-directed attention caused increased responsivity to the fearful affect and made subjects more likely to withdraw from the situation, regardless of the fact that a behavioral standard existed which called for an opposite response. The theoretical and behavioral implications of the findings were discussed.     

Acoustic measures of stutterers'' speech following an intensive therapy program

Characteristics of consonant-vowel duration and vocal fundamental frequency (F₀) are reported for 12 school-age stuttering males. Subjects' speech was recorded pre- and post- therapy and at 2-mo follow-up. Mean F₀ and voice onset time values remained stable from pretherapy to 2-mo follow-up, and an increase of 12% vocalized time was maintained across all posttherapy samples. It is suggested that increases in speech fluency may not be accompanied by changes in fundamental timing gestures. Increased speech fluency may be accomplished through increases in vocalized time permitting adjustments in motor sequencing which accompany stuttering.
